    TECHNICAL AREA
    The present invention relates to a vehicle light which is equipped with a fire unit having a plurality of light sources.
    PRIOR ART
    Vehicle lights that are equipped with a fire unit having a plurality of light sources are known. A fire unit of such a vehicle fire is disclosed in JP-A-2013-243080.
    This fire unit is configured to form a horizontally long light distribution pattern or a portion thereof by selectively illuminating one or more of the light sources.
    By using the vehicle light disclosed in the above patent document, the necessary forward visibility is provided for the driver of his own vehicle without bringing the driver of a vehicle approaching or departing. a vehicle to be dazzled.
    However, even when such a vehicle light is used, to further improve the forward visibility of the driver of his own vehicle, we want a configuration that can form a light distribution pattern that is brighter in its main area.
    SUMMARY OF THE INVENTION
    The present invention has been made in view of the above circumstances, and an object of the present invention is therefore to provide a vehicle light which comprises a fire unit having a plurality of light sources and which can improve the forward visibility of the driver of his own vehicle without causing the driver of an approaching vehicle or a vehicle to be dazzled.
    The present invention provides a vehicle light comprising a first fire unit having a plurality of first light sources, characterized in that: the vehicle light further comprises a second fire unit having a second light source; the first fire unit is configured to form a first horizontally long light distribution pattern or part thereof when one or more of the first light sources are selectively illuminated; the second fire unit is configured to form a second light distribution pattern which is smaller and brighter than the first light distribution pattern when the second light source is turned on; and at least the second fire unit of the first fire unit and the second fire unit is configured to be able to pivot in a horizontal plane.
    The type and specific configuration of the first light sources and the second light source are not limited to particular types and configurations.
    The first light distribution pattern and the second light distribution pattern may be such that they are capable of forming a high beam light distribution pattern when they are combined or are capable of forming, when they are combined, an additional light distribution pattern which is added to a low beam light distribution pattern by forming a traffic light distribution pattern.
    There are no particular limitations to the positional relationship between the first unit of fire and the second unit of fire. For example, they can be arranged in two stages in the vertical direction or be arranged side by side in the left-right direction.
    In the vehicle light according to the present invention, a first horizontally long light distribution pattern or part thereof is formed by selecting the ignition of one or more of the first light sources of the first unit. of fire.
    This makes it possible to ensure a necessary forward visibility of the driver of his own vehicle without bringing the driver of a vehicle approaching or a vehicle in front to be dazzled.
    The second light distribution pattern which is smaller and brighter than the first light distribution pattern is further formed by turning on the second light source of the second fire unit. The first light distribution pattern and the second light distribution pattern are combined so that an area of high light intensity is formed as an overlap thereof.
    Since at least the second unit of fire among the first unit of fire and the second unit of fire is configured to be able to rotate in a horizontal plane, the area of high light intensity can be shifted in the left-right direction depending on a vehicle traveling situation.
    This makes it possible to improve the forward visibility of the driver of his own vehicle without bringing the driver of an approaching vehicle or a vehicle to be dazzled.
    The present invention thus provides a vehicle light which is equipped with a fire unit having a plurality of light sources and which can improve the visibility towards the front of the driver of his own vehicle without bringing the driver of the vehicle. a vehicle approaching or a vehicle to be dazzled.
    In the above configuration, the first light sources may be light emitting diodes, in which case a first horizontally long light distribution pattern or a portion thereof may be formed with high positional accuracy. The second light source may be such that it uses a laser diode, in which case a second light distribution pattern that is smaller and brighter than the first light distribution pattern can be formed easily.
    In the above configuration, the first fire unit and the second fire unit may be configured to be able to pivot together in a horizontal plane, in which case the area of high light intensity may be shifted into the left-right direction according to a vehicle traveling situation while maintaining the positional relationship between the first light distribution pattern and the second light distribution pattern constant.
    The above configuration may be modified so that the first unit of fire further has a reflector which reflects, towards the front side of a vehicle, beams of light emitted by the first light sources, and the first light sources are arranged side by side in the vehicle width direction. In this case, a first horizontally long light distribution pattern or part thereof can be formed by a simple configuration.
    In the above configuration, two sets of a first unit of fire and a second unit of fire may be provided. In this case, two sets of a first pattern of light distribution and of a second light distribution pattern can be formed. By combining these light distribution patterns, a control to improve the driver's forward visibility of his own vehicle can be meticulously performed without causing the driver of an approaching vehicle or a vehicle to be dazzled. .

    DETAILED DESCRIPTION
    Embodiments of the present invention are described below with reference to the drawings.
    A first embodiment of the present invention is described below.
    Figure 1 is a front view of a vehicle fire assembly 10 according to the first embodiment.
    As shown in FIG. 1, the vehicle light assembly 10 is equipped with a pair of fire modules (left and right) 20L and 20R, a control unit 50, a on-vehicle camera 52 for filming a scene in front of the vehicle, a vehicle speed sensor 54, and a steering angle sensor 56.
    The modules of the pair of fire modules 20L and 20R are arranged at the front-left and front-right corners of a vehicle and are configured to be symmetrical from left to right with respect to the other. Each of the light modules 20L and 20R is housed in a lamp chamber which is formed by a body of fire and a transparent panel (neither of which is shown).
    Each of the fire modules 20L and 20R is equipped with a first fire unit 22A and a second fire unit 22B which are arranged side by side in the left-right direction, a support frame 24 which supports, a pivot mechanism 26 for pivoting the first fire unit 22A and the second fire unit 22B about a vertical axis Ax with the support frame 24.
    A signal of the image data captured by the camera on board the vehicle 52, a vehicle speed signal generated by the vehicle speed sensor 54, and a steering angle signal generated by the sensor of the vehicle steering angle 56 are entered into the control unit 50. On the basis of these input signals, the control unit 50 carries out drive commands on the pivot mechanisms 26 in an individual manner and performs start / stop commands on the first fire units 22A and the second fire units 22B of the fire modules 20L and 20R in an individual manner.
    Since, as has been described above, the pair of fire modules 20L and 20R are symmetrical from left to right relative to each other, the configurations of the first fire unit 22A and of FIG. the second fire unit 22B of the left fire module 20L (right when seen from the front side) will be described below.
    Figures 2A and 2B are sectional views along line IIa-IIa and line IIb-IIb in Figure 1, respectively.
    As can be seen from these figures, the first fire unit 22A and the second fire unit 22B are parabolic fire units.
    The first fire unit 22A is equipped with a light source unit 30A having four first light sources 32A, a reflector 34A for reflecting forward of the output light of the source unit 30A, and a base member 36A which supports the light source unit 30A and the reflector 34A.
    In the first fire unit 22A, the first light sources 32A of the light source unit 30A are white light emitting diodes. That is, the first four light sources 32A, each of which is a light emitting chip of a white light emitting diode, are arranged side by side in the vehicle width direction with their light emitting surfaces facing upward. .
    The reflector 34A is arranged to cover the light source unit 30A from above. A reflective surface 34Aa of the reflector 34A is formed by a plurality of reflection elements 34As which reflect, in a controlled manner, light from each of the first four light sources 32A.
    The base member 36A is a plate-shaped member and extends in a horizontal plane.
    On the other hand, the second fire unit 22B is equipped with a light source unit 30B having a second single light source 32B, a reflector 34B for reflecting outwardly from the exit light of the light source. second light source 32B, and a base member 36B which supports the light source unit 30B and the reflector 34B.
    In the second fire unit 22B, a laser diode 32C is used for the second light source 32B of the light source unit 30B. That is, the second light source 32B is phosphor which emits white light when irradiated with laser light emitted by the laser diode 32C. The second light source 32B is arranged in such a way that its light-emitting surface is directed upwards.
    The reflector 34B is arranged to cover the second light source 32B from above. A reflective surface 34Ba of the reflector 34B is formed by a plurality of reflection elements 34Bs which reflect, in a controlled manner, the light from the second light source 32B.
    The base element 36B is a plate-shaped element and extends in a horizontal plane. The base member 36B is formed with an opening 36Ba through which laser light emitted by the laser diode 32C passes to irradiate the second light source 32B.
    Each of the light modules 20L and 20R is configured such that the first four light sources 32A are turned on or off together or a selected portion thereof is turned on or off under control of the light. The second light source 32B is configured to be turned on or off with an appropriate timer.
    FIG. 3A is a transparent view showing a PHI road light distribution pattern which is formed by the illumination light emitted by the vehicle light assembly 10 according to the embodiment on a screen virtual vertical located 25 meters in front of the vehicle.
    The PHI road light distribution pattern is a light distribution pattern which is formed in a state such that the fire modules 20L and 20R are directed directly forward (i.e. that the pivot mechanisms 26 are not driven, hereinafter referred to as the reference state) and the first fire units 22A and the second fire units 22B of the fire modules 20L and 20R are all on.
    The PHI road light distribution pattern is a composite light distribution pattern of a PL light distribution pattern shown in FIG. 3B and a PR light distribution pattern shown in FIG. 3C.
    The light distribution pattern PL shown in FIG. 3B is a light distribution pattern which is formed by the illumination light emitted by the left-hand fire module 20L, and is a composite light distribution pattern. a first PLI light distribution pattern which is formed by illumination light emitted by the first light unit 22A and a second light distribution pattern PL2 which is formed by illumination light emitted by the second fire unit 22B.
    The first PLI light distribution pattern is a horizontally long light distribution pattern which is relatively short on the right side of a vertical line VV which cuts a vanishing point HV located in front of the set of light. 10, and is relatively long on the left side of the vertical line VV. In the vertical direction, the first PLI light distribution pattern is wider above a horizontal line H-H which intersects the H-V point than below the horizontal line H-H.
    The first PLI light distribution pattern is a light distribution pattern that is formed when the first four light sources 32A of the light source unit 30A are simultaneously illuminated, and therefore consists of four patterns. PLla, PLlb, PLlc, and PLld.
    The four light distribution patterns PLa1, PL1b, PL1c, and PLld have approximately rectangular contours and are approximately the same size. The adjacent distributions of these light distribution patterns PLa1, PL1b, PL1, and PLld overlap each other in the left-right direction, and the vertical line VV intersects the second right light distribution pattern PL1b in a position that is a little closer to its right edge than to its left edge.
    The second light distribution pattern PL2 is a light distribution pattern which is smaller and brighter than the first PLI light distribution pattern, and is a dot-shaped light distribution pattern which is a slightly longer in the horizontal direction than in the vertical direction and is centered on the point HV. The horizontal width of the second light distribution pattern PL2 is provided approximately the same or a little larger than that of each of the light distribution patterns PLla to PLld.
    Since the 32C laser diode is used for the second light source 32B of the second fire unit 22B, the second light distribution pattern PL2 is a very bright light distribution pattern.
    The light distribution pattern PR shown in FIG. 3C is a light distribution pattern which is formed by the illumination light emitted by the right light module 20R, and is a composite light distribution pattern. a first light distribution pattern PR1 which is formed by illumination light emitted by the first light unit 22A and a second light distribution pattern PR2 which is formed by illumination light emitted by the second fire unit 22B.
    The first light distribution pattern PR1 is symmetrical from left to right with the first PLI light distribution pattern with respect to the vertical line V-V and in the shape and distribution of light intensity. That is, the first light distribution pattern PR1 is composed of four light distribution patterns PR1a, PR1b, PR1c, and PRd1 which are symmetrical from left to right with the four light distribution patterns PLa1, PLlb, PLlc, and PLld, respectively, with respect to the vertical line VV.
    The second light distribution pattern PR2 is symmetrical from left to right with the second light distribution pattern PL2 with respect to the vertical line V-V in the shape and distribution of light intensity.
    As shown in FIG. 3A, the PHI road light distribution pattern, which is formed in such a way that the pair of PL and PR light distribution patterns (left and right) overlap each other, is, as a whole, a horizontally long light distribution pattern extending to the left and right of the vertical line VV.
    While the PHI road light distribution pattern is wider above a horizontal line HH than below the horizontal line HH, its area of high luminous intensity HZ which is centered on the point HV is of a very strong luminous intensity. This is because the pair of second light distribution patterns (left and right) PL2 and PR2 are small and bright and occupy the same area around the point H-V.
    With the formation of the PHI road light distribution pattern described above, the forward visibility of the driver of his own vehicle is made sufficiently large when, for example, the vehicle moves in line right at high speed.
    In addition, by shifting the PHI road light distribution pattern to the left or to the right depending on a vehicle traveling situation, the forward visibility of the driver of his own vehicle is made sufficiently large even when, for example, the vehicle moves along a winding road.
    FIGS. 4A to 4C to 8A to 8C show light distribution patterns of each of which a portion of the light distribution patterns components of the PHI road light distribution pattern are missing. Figs. 4A to 4C and Figs. 5A to 5C show the light distribution patterns that are formed by examples of a first light distribution control. Figs. 6A-6C-8A-8C show light distribution patterns that are formed by examples of a second light distribution control.
    A description of light distribution patterns formed by the first light distribution control will first be made.
    FIG. 4A shows a PM1A light distribution pattern which is different from the PHI road light distribution pattern shown in FIG. 3A in that part of the first PLI light distribution pattern is missing in the first of the complete left light distribution pattern PL and part of the first light distribution pattern PR1 of the complete right light distribution pattern PR, and in that, in the first, the right light distribution pattern PR is slightly shifted to the left in relation to its position in the reference state.
    More specifically, the rightmost light distribution pattern PLla of the four light distribution patterns PLla PLld constituting the first complete light distribution pattern PLI is missing in the left light distribution pattern PL represented in FIG. Figure 4B. In this left light distribution pattern PL, a right end portion of the second light distribution pattern PL2 protrudes to the right of the right edge of the light distribution pattern PLlb.
    On the other hand, the second left light distribution pattern PRlb and the third left light distribution pattern PRlc of the four light distribution patterns PRla to PRld constituting the first complete light distribution pattern PR1 are missing in the PR light distribution pattern shown in FIG. 4C. In this right light distribution pattern PR, more than the right half of the second light distribution pattern PR2 protrudes to the right with respect to the right edge of the light distribution pattern PR1a.
    As shown in FIG. 4A, in the light distribution pattern PM1A, the light distribution pattern PRld is placed in the vicinity of a vehicle that approaches relatively distantly 2 by shifting the distribution pattern of right light PR slightly to the left in relation to its position in the reference state.
    As described above, since the light distribution pattern PM1A is such that the second light distribution pattern PL2 of the left light distribution pattern PL and the light distribution pattern PRld of the light pattern PR right light distribution are located to the left and right of the approaching vehicle 2, respectively, a necessary visibility can be provided for the road ahead without bringing the driver of the vehicle approaching 2 to be dazzled.
    In addition, in the PM1A light distribution pattern, the second light distribution pattern PL2 and the light distribution pattern PL1b of the left light distribution pattern PL and the second light distribution pattern PR2 of the pattern The right-hand light distribution PR has an overlap around the point HV, so that a distant road zone in front can be strongly illuminated.
    The position of the approaching vehicle 2 is detected by the control unit 50 which calculates a width, a central position, and so on. of the approaching vehicle 2 on the image database of the approaching vehicle 2 which is inputted from the camera on board the vehicle 52. The control unit 50 shifts the right light distribution pattern PR to the left or right by driving the pivoting mechanism 26 of the fire module 20R.
    A light distribution pattern PM1B shown in Fig. 5A is different from the light distribution pattern PM1A shown in Fig. 4A in that the right light distribution pattern PR of the first is shifted to the right in some degree. measure relative to its position in the reference state (see Figure 5C).
    With this light distribution configuration PM1B in which the second light distribution pattern PR2 and the light distribution pattern PRld of the right light distribution pattern PR are located to the left and right of the approaching vehicle. 2, respectively, even when the approaching vehicle 2 arrives even closer to its own vehicle, necessary visibility can be provided for the road ahead without causing the driver of the approaching vehicle 2 to be dazzled.
    In addition, in the light distribution pattern PM1B, the second light distribution pattern PL2 and the light distribution pattern PL1b of the left light distribution pattern PL and the second light distribution pattern PR1a of the pattern right light distribution PR have an overlap around the point HV.
    The second light distribution pattern PR2 of the right light distribution pattern PR is immediately to the right of these light distribution patterns, so that a far-away road area can be strongly illuminated.
    A description of light distribution patterns formed by the second light distribution control will then be made.
    FIG. 6A shows a PM2A light distribution pattern which is different from the PHI road light distribution pattern shown in FIG. 3A in that in the first part a portion of the first PLI light distribution pattern is missing. of the complete left light distribution pattern PL and part of the first light distribution pattern PR1 of the complete right light distribution pattern PR, and in that in the first the right light distribution pattern PR is shifted to the right to a large extent in relation to its position in the reference state.
    More specifically, the rightmost light distribution pattern PLla of the four light distribution patterns PLla PLld constituting the first complete light distribution pattern PLI is missing in the left light distribution pattern PL represented in FIG. Figure 6B. On the other hand, the leftmost light distribution pattern PRla of the four light distribution patterns PRla to PRld constituting the first complete light distribution pattern PR1 is missing in the right light distribution pattern PR shown in FIG. 6C.
    In the PM2A light distribution pattern, the second light distribution patterns PL2 and PR2 are situated to the left and to the right of a vehicle that approaches relatively far away 2, respectively, by shifting the distribution pattern of PR right light to the right in a large measure relative to its position in the reference state.
    With this PM2A light distribution pattern, the necessary visibility can be ensured for the road ahead thanks to the second light distribution patterns PL2 and PR2 located to the left and to the right of the approaching vehicle 2 without bringing the driver of the vehicle approaching 2 to be dazzled.
    In addition, in the PM2A light distribution pattern, the second light distribution pattern PL2 and the light distribution pattern PL1b of the left light distribution pattern PL have an overlap around the point HV, so that a distant road zone ahead can be strongly lit.
    A PM2B light distribution pattern shown in FIG. 7A is different from the PM2A light distribution pattern shown in FIG. 6A in that the first left light distribution pattern PR1b of the first distribution pattern is missing in the first light distribution pattern. PR1 and the second light distribution pattern PR2 of the right light distribution pattern PR, and in that the rightmost light distribution pattern PLa of the left light distribution pattern PL is restored in the first see Figures 7B and 7C).
    With this PM2B light distribution configuration, even when the approaching vehicle 2 arrives even closer to its own vehicle, a necessary visibility can be ensured for the road ahead thanks to the PLLA light distribution pattern of the first PLI light distribution pattern and the light distribution pattern PRlc of the first light distribution pattern PR1 which are to the left and to the right of the approaching vehicle 1, respectively, without bringing the driver of the approaching vehicle 2 to be dazzled.
    In addition, in the light distribution pattern PM2B, the second light distribution pattern PL2 and the light distribution pattern PL1b of the left light distribution pattern PL have an overlap around the point HV, so that a distant road zone ahead can be strongly illuminated.
    FIG. 8A shows a PM3A light distribution pattern which is different from the PHI road light distribution pattern shown in FIG. 3A in that a portion of the first PLI light distribution pattern of the complete left light distribution PL and part of the first light distribution pattern PR1 of the complete right light distribution pattern PR are missing in the first, and in that the left light distribution pattern PL and the light distribution pattern PR line are offset from their positions in the reference state in such directions that they deviate from each other.
    Specifically, the rightmost light distribution pattern PLla of the four light distribution patterns PLla PLld constituting the first complete light distribution pattern PLI is missing in the left light distribution pattern PL represented in FIG. Figure 8B. On the other hand, the leftmost light distribution pattern PRla of the four light distribution patterns PRla to PRld constituting the first complete light distribution pattern PR1 is missing in the right light distribution pattern PR shown in FIG. 8C.
    In the light distribution pattern PM2C, the second light distribution patterns PL2 and PR2 are situated to the left and to the right of a vehicle 4 in front, respectively, by shifting the left light distribution pattern PL towards the left to some extent with respect to its position in the reference state and shifting the right light distribution pattern PR to the right relative to its position in the reference state by the same distance as the distribution pattern left light PL.
    With this PM2C light distribution pattern, a necessary visibility can be provided for the road ahead without bringing the driver of the vehicle 4 in front to be dazzled.
    In addition, in the light distribution pattern PM2C, the second light distribution patterns PL2 and PR2 which are situated to the left and to the right of the vehicle 4 in front, respectively, are relatively close to the vertical line VV, so that a distant road zone ahead can be strongly lit.
    It should be noted that, by varying the interval between the left and right light distribution patterns PL and PR as a function of the distance between the own vehicle and a vehicle 4 in front, a forward visibility of the The driver of his own vehicle can be maximized without causing the driver of the vehicle 4 to be dazzled.
    The operation and advantages of the embodiment will then be described.
    Equipped with the pair of light modules 20L and 20R to form a pair of light distribution patterns (left and right) PL and PR, the vehicle light assembly 10 according to the embodiment can form the pattern PHI traffic light distribution system in the form of a composite light distribution pattern of the pair of light distribution patterns (left and right) PL and PR.
    Each of the fire modules 20L and 20R is equipped with the first fire unit 22A having the first four light sources 32A and the second fire unit 22B having the second single light source 32B. A first full length horizontal PLI or PR1 light distribution pattern or part thereof is formed by selectively illuminating one or more of the first four light sources 32A of each first unit. of fire 22A. As a result, a necessary forward visibility of the driver of his own vehicle can be ensured without causing the driver of an approaching vehicle or a vehicle to be dazzled.
    The second light source 32B of the second fire unit 22B of each of the fire modules 20L and 20R is further turned on to form a second light distribution pattern PL2 or PR2 which is smaller and brighter than the first PLI or PRl light distribution pattern. An area of high luminous intensity HZ may be formed as a superposition of the first light distribution pattern PL1 or PR1 and the second light distribution pattern PL2 or PR2.
    In addition, each of the fire modules 20L and 20R is configured in such a way that the first fire unit 22A and the second fire unit 22B can be pivoted in a horizontal plane, the area of high luminous intensity HZ can be shifted in the left-right direction according to a vehicle movement state, so that the driver's forward visibility of his own vehicle can be improved without bringing the driver of a vehicle approaching or a vehicle to be dazzled.
    Thus, the vehicle fire assembly 10 according to the embodiment which is equipped with the first fire units 22A each having the first four light sources 32A can improve the forward visibility of the driver of his own vehicle. without causing the driver of an approaching vehicle or a vehicle to be dazzled.
    In addition, according to the embodiment, since the first light sources 32A of each first fire unit 22A are light-emitting diodes, a first horizontally long light distribution pattern PLI or PR1 or a part thereof can be formed with high positional accuracy. Since the 32C laser diode is used for each second light source 32B, a second light distribution pattern PL2 or PR2 that is smaller and brighter than the first light distribution pattern PL1 or PR1 can be formed easily.
    According to the embodiment, since the first fire unit 22A and the second fire unit 22B of each of the fire modules 20L and 20R are pivoted together, the zone of high luminous intensity HZ can be shifted in the left direction -right depending on a state of vehicle movement while the positional relationship between a first light distribution pattern PLI or PR1 and a second light distribution pattern PL2 or PR2 is kept constant. This always projects a sufficient amount of light in a direction of vehicle travel.
    Furthermore, according to the embodiment, since in each first fire unit 22A beams of light emitted by the first four respective light sources 32A arranged in the vehicle width direction are reflected towards the front side of the vehicle. a first horizontally complete long light distribution pattern PLI or PR1 or part thereof may be formed by a simple configuration.
    In addition, since the vehicle fire assembly 10 according to the embodiment is equipped with two sets of a first fire unit 22A and a second fire unit 22B, by combining two sets of a first light distribution pattern PLI or PR1 and a second light distribution pattern PL2 or PR2 formed by them, the control for improving the forward visibility of the driver of the own vehicle can be carried out meticulously without bring the driver of an approaching vehicle or a vehicle in front to be dazzled.
    Although, in the embodiment, light-emitting diodes are used as first light sources 32A of each first fire unit 22A and a laser diode is used for the second light source 32B of each second fire unit 22B other types of light sources may be used.
    Although, in the embodiment, each first fire unit 22A is equipped with the first four light sources 32A, it can be equipped with three or less or five or more first light sources 32A.
    Although, in the embodiment, the first fire unit 22A and the second fire unit 22B of each of the fire modules 20L and 20R are both a parabolic fire unit, one of the two or both may be of another type of fire unit such as a projector type fire unit or a direct projection type fire unit.
    Although, in the embodiment, the pair of fire modules 20L and 20R is disposed at the front-left and front-right corners of the vehicle, it can be arranged in different positions.
    In the embodiment, the camera embedded in the vehicle 52, the vehicle speed sensor 54, and the steering angle sensor 56 are connected to the control unit 50. Another configuration is possible in which a navigation apparatus is connected to the control unit 50 in addition to these devices and the drive commands for the pivoting mechanisms 26 and the start / stop commands for the first fire units 22A and the second 22B fire units are performed using the navigation apparatus.
    A second embodiment of the present invention will next be described.
    Figure 9 is a front view of a vehicle fire assembly 110 according to the second embodiment.
    As can be seen from FIG. 9, while the vehicle light assembly 110 is of the same basic configuration as the vehicle light assembly 10 according to the first embodiment, the first is different from the last in some of the 120L and 120R fire module configurations.
    That is to say, while the first fire unit 22A and the second fire unit 22B of each of the fire modules 120L and 120R have the same configurations as those of each of the fire modules 20L and 20R of the first embodiment, the first are different from the last in the support structure.
    More specifically, in each of the fire modules 120L and 120R, the second fire unit 22B is supported by a support frame 124 via a pivoting mechanism 126 and the first fire unit 22A is supported. directly by the support frame 124. With this structure, only the second fire unit 22B can be pivoted about a vertical axis Ax by the pivoting mechanism 126. The support frame 124 is supported by a fire body (no represented), for example.
    Fig. 10A is a transparent view showing a road light light distribution pattern PH2 which is formed by illumination light emitted by the light assembly 110 according to the embodiment.
    The traffic light light distribution pattern PH2 is a light distribution pattern which is formed in a state such that the first fire units 22A and the second fire units 22B of the fire modules 120L and 120R which are in the reference state are all on.
    The traffic light light distribution pattern PH2 is a composite light distribution pattern of a light distribution pattern PL shown in FIG. 10B and a light distribution pattern PR shown in FIG. 10C.
    The light distribution pattern PL shown in FIG. 10B is a light distribution pattern which is formed by the illumination light emitted by the left light module 120L, and is a composite light distribution pattern. a first PLI light distribution pattern which is formed by illumination light emitted by the first fire unit 22A and a second light distribution pattern PL2 which is formed by illumination light emitted by the second fire unit 22B.
    The first PLI light distribution pattern is the same as that of the first embodiment (see FIG. 3B) except that it is formed to the left of that of the first embodiment. The vertical line V-V intersects the rightmost light distribution pattern PLla in a position that is closer to its left edge than its right edge.
    The second light distribution pattern PL2 is the same as that of the first embodiment (see Figure 3C) including the position.
    The light distribution pattern PR shown in Fig. 10C is a light distribution pattern which is formed by illumination light emitted by the right light module 120R, and is a composite light distribution pattern. a first light distribution pattern PR1 which is formed by the illumination light emitted by the first fire unit 22A and a second light distribution pattern PR2 which is formed by the illumination light emitted by the second fire unit 22B.
    The first light distribution pattern PR1 and the second light distribution pattern PR2 are symmetrical from left to right with the first light distribution pattern PLI and the second light distribution pattern PL2 with respect to the vertical line VV in shape and luminous intensity distribution, respectively.
    As shown in FIG. 10A, the traffic light light distribution pattern PH2, which is formed in such a way that the pair of light distribution patterns (left and right) PL and PR are overlap each other and the pair of light distribution patterns (left and right) PLa and PRla overlap each other, is, as a whole, a horizontally long light distribution pattern which extends left and right of the vertical line VV.
    The traffic light light distribution pattern PH2 is thus a horizontally long light distribution pattern that extends to the left and to the right over distances even longer than the fire light distribution pattern. PHI road. of the first embodiment.
    In the traffic light distribution pattern PH2 also, since the pair of second light distribution patterns (left and right) PL2 and PR2 which are small and bright occupies the same area around the point HV, its zone of high luminous intensity HZ which is centered on the point HV is of a very strong luminous intensity.
    With the formation of the PH2 road light distribution pattern described above, the forward visibility of the driver of his own vehicle is made sufficiently large when, for example, the vehicle moves in line right at high speed.
    In addition, by shifting the second light distribution patterns PL2 and PR2 to the left or to the right depending on a vehicle traveling situation, the visibility towards the front of the driver of his own vehicle is made sufficiently large. even when, for example, the vehicle moves along a winding road.
    FIGS. 11A to 11C and FIGS. 12A to 12C show light distribution patterns in each of which a portion of the component light distribution patterns of the PH2 traffic light distribution pattern are missing.
    Fig. 11A shows a PM3A light distribution pattern which is different from the road light light distribution pattern PH2 shown in Fig. 10A in that part of the first PLI light distribution pattern of the light pattern. complete left light distribution PL and part of the first light distribution pattern PR1 of the complete right light distribution pattern PR is missing in the first, in that, in the first, the second light distribution pattern PL2 the left light distribution PL is shifted to the left to a small extent with respect to its position in the reference state, and in that, in the first, the second light distribution pattern PR2 of the right light distribution pattern PR is shifted to the right to a large extent relative to its position in the reference state.
    More specifically, the rightmost light distribution pattern PLla of the four light distribution patterns PLla PLld constituting the first complete light distribution pattern PLI is missing in the left light distribution pattern PL represented in FIG. Figure 11B. On the other hand, the second left light distribution pattern PRlb of the four light distribution patterns PRla to PRld constituting the first full light distribution pattern PR1 is missing in the right light distribution pattern PR shown in Fig. 11C.
    In the light distribution pattern PM3A, the second light distribution pattern PL2 of the left light distribution pattern PL is shifted to the left to a small extent relative to its position in the reference state, from so that its right edge is made to coincide with the right edge of the PRla light distribution pattern of the first light distribution pattern PR1. And the second light distribution pattern PR2 of the right light distribution pattern PR is shifted to the right to a large extent relative to its position in the reference state, so that its left edge is made to coincide with the left edge of the light distribution pattern PRlc of the first light distribution pattern PR1.
    With the PM3A light distribution pattern, a necessary visibility can be ensured for the road ahead by the combination of the second light distribution pattern PL2 and the light distribution pattern PRla and the combination of the second light distribution pattern PR2 light and PRlc light distribution pattern, the two combinations being located to the left and right of a vehicle that approaches relatively distant 2, respectively, without bringing the driver of the approaching vehicle 2 to be dazzled.
    In addition, in the PM3A light distribution pattern, the second light distribution pattern PL2 and the light distribution pattern PRla have an overlap around the point HV, so that a distant road zone ahead can to be strongly enlightened.
    On the other hand, in the embodiment, as indicated by a dashed line in Fig. 11C, the second light distribution pattern PL2 of the right light distribution pattern PR is shifted with respect to its position in the reference state to a position on the right of the approaching vehicle 2. In the embodiment, this is done in such a way that the second light source 32B of the second fire unit 22B of the 120R right light module is off when in the reference state, then the second fire unit 22B is rotated clockwise, and finally the second light source 32B is turned on again. With this measurement, the PM3A light distribution pattern can be formed without causing the driver of the approaching vehicle 2 to be dazzled involuntarily.
    A light distribution pattern PM3B shown in FIG. 12A is different from the light distribution pattern PM3A shown in FIG. 11A in that the third left light distribution pattern PR1c of the first light distribution pattern PR1 of FIG. PR light distribution pattern PR is furthermore missing in the first and second light distribution pattern PR2 of the right light distribution pattern is shifted further to the right (see FIG. 12C).
    With the PM3B light distribution configuration, even if the approaching vehicle 2 comes even closer to its own vehicle, a necessary visibility can be ensured for the road ahead by the second PL2 light distribution patterns and PR2 which are to the left and right of the approaching vehicle 2, respectively, without bringing the driver of the approaching vehicle 2 to be dazzled.
    In addition, in the light distribution pattern PM3B also, the second light distribution pattern PL2 and the light distribution pattern PRla have an overlap around the point HV, so that a distant road zone in front of can be strongly illuminated.
    FIGS. 13A to 13C and FIGS. 14A to 14C show exemplary modified traffic light distribution patterns which are formed by illumination light emitted by vehicle light 110 according to the second mode. of realization.
    Fig. 13A shows a PM3 traffic light distribution pattern which is different from the road light light distribution pattern PH2 shown in Fig. 10A in that the rightmost light distribution pattern PLa of the first PLI light distribution pattern of the left light distribution pattern PL and the leftmost light distribution pattern PRla of the first light distribution pattern PR1 of the right light distribution pattern PR (see Figs. 13B and 13C) of the first are brighter than those of the latter.
    The brighter light distribution patterns PLla and PRla are formed by increasing the current delivered to the first light source 32A 'to form the light distribution pattern PLla or PRla among the first four light sources 32A of each fire modules 20L and 20R.
    While the PM3 traffic light distribution pattern has the same shape as the traffic light light distribution pattern PH2 shown in FIG. 10A, the former is different from the latter in that the patterns of brighter light distribution PLla and PRla, in addition to the pair of second light distribution patterns (left and right) PL2 and PR2 which are small and bright, overlap around point HV. Thus, its zone of high luminous intensity HZ which is centered on the point H-V is of a very strong luminous intensity.
    Fig. 14A shows a PM4 road light distribution pattern which is different from the road light light distribution pattern PH2 shown in Fig. 10A in that the second light distribution patterns PL2 and PR2. of the left light distribution pattern PL and the right light distribution pattern PR of the first are shifted to the right in certain measurements with respect to their positions in the reference state (see FIGS. 14B and 14c), and in that that the second left light distribution pattern PR1b and the third left light distribution pattern PR1c of the first light distribution pattern PR1 of the right light distribution pattern PR of the first (see Fig. 14c) are brighter than those of the first light distribution pattern PR1c latest.
    The distance of the shift to the right with respect to the position in the reference state of the second light distribution pattern PR2 of the right light distribution pattern PR is a little longer than that of the second light distribution pattern. PL2 of the left light distribution pattern PL, so that the two second light distribution patterns PR2 and PL2 overlap each other by being spaced from each other in the left-right direction.
    With the PH4 road light distribution pattern described above, sufficient visibility can be ensured for the road ahead even if it is curved to the right.
    Since the second light distribution patterns PR2 and PL2 overlap each other while being separated from each other in the left-right direction, the visibility of the road ahead can be further improved.
    Sufficient visibility can always be ensured for the road ahead by correctly shifting the positions of the second light distribution patterns PR2 and PL2 or switching the light distribution pattern (s) in order to increase the brightness of the four patterns of light. light distribution PRla to PRld constituting the first complete light distribution pattern PR1 of the right light distribution pattern PR as a function of the curvature of the road ahead.
    Instead of the PM3A light distribution pattern shown in Fig. 11A, a PM4A light distribution pattern shown in Fig. 15A can be formed in which the PRla and PRlc light distribution patterns on the left and to the right of a vehicle approaching 2, respectively, are of increased brightness (see Figure 15C).
    With the light distribution pattern PM4A, the visibility of the road ahead can be further improved without causing the driver of the approaching vehicle 2 to be dazzled.
    Particular numerical values of dimensions used in the embodiments and their modifications are just examples, and it goes without saying that different values may be used instead as appropriate.
    The present invention is not limited to the embodiments and their modifications above and various other modifications are possible.
