    DETAILED DESCRIPTION
    [0036] Illustrative embodiments of the invention will be described in detail below with reference to the drawings.
    Fig. 1 is a vertical sectional view showing a schematic structure of a vehicle light according to an illustrative embodiment of the invention, and Fig. 2 is a front view of a light source unit of the illustrative embodiment.
    A vehicle light 1 of the first exemplary embodiment is a fire unit for a road surface pattern (road surface patterning device) mounted on at least one headlight of a pair of headlights provided on right and left sides of a front of a vehicle. Figure 1 shows a structure of the fire unit for the road surface pattern mounted on a headlight, as a vehicle light 1.
    As shown in Figure 1, the vehicle light 1 comprises a fire body 2 having an opening formed on a front side of the vehicle and a transparent cover 4 fixed so as to cover the opening of the body of fire 2. The transparent cover 4 is formed of resin, glass or the like having a transparency. In a fire chamber 3 formed by the fire body 2 and the transparent cover 4 are received a light source unit 10, a projection lens 20 and a mask 30. The respective constituent elements are fixed on the fire body 2 by a support mechanism (not shown).
    As shown in FIGS. 1 and 2, the light source unit 10 comprises a printed circuit 11 and a first light source group 12 and a second light source group 15 mounted on the printed circuit board. 11. The first light source group 12 is configured by a plurality of light emitting diodes (eight light emitting diodes here) (an example of a first light emitting element) disposed along a right and left direction of the vehicle light. 1. Similarly, the second light source group 15 is configured by a light emitting diode (an example of a second light emitting element) disposed above the first light source group 12, for example. At the same time, the first and second light source groups 12, 15 may be configured by semiconductor light emitting elements other than the light emitting diodes. Similarly, the numbers of light-emitting diodes configuring the first and second light source groups 12, 15 are not limited to the example shown. As shown in Fig. 2, each of the light emitting diodes configuring the first light source group 12 and the second light source group 15 has a generally square light emission surface. At the same time, each light-emitting diode may have a light emitting surface other than the square shape, such as a rectangular shape. A light source image to be formed by light from each light emitting diode preferably has a size of 0.5 to 1.5, which is a ratio of a width in an upper and a lower direction over a width in the right and left direction, when a width of the vehicle in the right and left direction is set to 1. Similarly, the respective light-emitting diodes can be turned on and off individually, in response to a control signal from a control device 40.
    As shown in Figure 1, the projection lens 20 has an incident surface 20a and an outlet surface 20b. The incident surface 20a is provided to face the light emitting surfaces of the first light source group 12 and the second light source group 15, and the exit surface 20b is provided to face the front of the light source traffic light. The exit surface 20b of the projection lens 20 is formed to have a non-spherical outer shape such that light from the first light source group 12 and light from the second light source group 15 are to be emitted. by being refracted continuously in predetermined directions with respect to incident angles of the lights. When an area of the projection lens 20 through which the light of the first light source group 12 is to pass is called the first area 20A and an area of the projection lens 20 through which the light of the second group of light sources 15 must pass is called second zone 20B, the projection lens 20 is configured as a lens whose first zone 20A and the second zone 20B have different light distribution control functions on the exit surface 20b. The projection lens 20 may have a desired light distribution characteristic by appropriately determining an outer shape of the incident surface 20a or the exit surface 20b, for example. For example, in the illustrative embodiment, the projection lens 20 serves as a diffusion lens in the upper and lower direction and the right and left direction to diffuse the light in the upper and lower direction of the light and in the direction right and left of the fire, in the first zone 20A, and as diffusion lens in the upper and lower direction to diffuse the light in the upper and lower direction of the fire, in the second zone 20B. At the same time, the projection lens 20 of the illustrative embodiment is preferably configured such that a position of a rear focal point fl of the first area 20A and a position of a rear focal point f2 of the second zone 20B are different from each other and the first light source group 12 and the second light source group 15 are respectively provided at the rear focal points f1, f2.
    The mask 30 is a flat plate-shaped element disposed between the light source unit 10 and the projection lens 20. The mask 30 is provided in a position in which light from the first source group of light 12 and the light of the second light source group 15 do not intersect each other before entering the projection lens 20. That is, in the vertical sectional view of 1, the mask 30 has a width greater than a parallel width of the first light source group 12 consisting of the plurality of light emitting diodes of a predetermined magnitude or more and is provided to extend from an area between the first light source group 12 and the second light source group 15 to the vicinity of the incident surface 20a of the projection lens 20. A lower surface 31 and an upper surface 32 of the mask 30 have been subjected to a matte black coating or equivalent for low reflectivity treatment. The lights from the first light source group 12 and the second light source group 15 are thus absorbed respectively on the upper and lower surfaces 31, 32 of the mask 30.
    The switching on and off of the respective light emitting diodes configuring the first light source group 12 and the second light source group 15, the emission intensity adjustment of the respective light emitting diode lights and the setting Flashing speed of the light-emitting diodes are made by the controller 40. The controller 40 can thus change the individual switching on and off of the respective light-emitting diodes and the intensities and flash rates of the respective light-emitting diodes. The controller 40 is implemented by a device and a circuit such as a computer central processing unit, a storage unit and the like, as a hardware configuration, and is implemented by a computer program or the like. as a software configuration. At the same time, the control device 40 is provided outside the fire chamber 3, as shown in FIG. 1. However, the control device 40 can be provided inside the control chamber. 3. The controller 40 is configured to receive signals from a light switch and the like (not shown) and to transmit a variety of control signals to the respective light-emitting diodes in response to the received signals.
    As shown in FIG. 3, the lights L1 emitted by each light-emitting diode of the first light source group 12 pass through an area below the lower surface 31 of the mask 30, are incident on the incident surface 20a. of the projection lens 20 and are then emitted by the exit surface 20b. That is, the light L1 emitted from the first light source group 12 passes through the first area 20A of the projection lens 20.
    Since the first zone 20A of the projection lens 20 serves as a diffusion lens in the upper and lower direction and the right and left direction, a light source image which is to be formed by the light L1 passes through the first zone 20A. , so that it extends equally in the upper and lower direction and in the right and left direction. At the same time, since the light L2 emitted upwardly from the first light source group 12 is absorbed by the lower surface 31 of the mask 30, the light L2 has little incident on the projection lens 20.
    As also shown in FIG. 3, the light L3 emitted from the second light source group 15 passes through an area above the upper surface 32 of the mask 30, is incident on the incident surface 20a. of the projection lens 20, and is then emitted by the exit surface 20b. That is, the light L3 emitted from the second light source group 15 is incident on the second area 20B of the projection lens 20. Since the second area 20B of the projection lens 20 serves as a lens in the upper and lower direction, a light source image to be formed by the light L3 passes through the second area 20B, so that it extends further in the upper and lower direction than in the right and left direction. At the same time, since the L4 light emitted downwards from the second light source group 15 is absorbed by the upper surface 32 of the mask 30, the light L4 has little incident on the projection lens 20.
    Fig. 4 shows an example of respective light distribution patterns, which are formed by light emitted from the first light source group and light emitted from the second light source group.
    As described above, the light L1 from each light emitting diode of the first light source group 12 is diffused to form a light source image extending equally in the upper and lower direction and in the right and left direction and is projected to the front of the fire. That is, the light source image of each light emitting diode of the first light source group 12 forms a light distribution pattern P having a substantially quadrangular shape on a virtual screen in front of the vehicle. Since the respective light-emitting diodes of the first light source group 12 are provided along the right and left direction of the vehicle light 1, when all the light-emitting diodes are lit, it is possible to form a horizontally long light distribution pattern. Ph (for example a traffic light distribution pattern) whose light distribution patterns P having an essentially quadrangular shape are provided in parallel in the right and left direction. Further, when the respective light emitting diodes of the first light source group 12 are individually turned on and off by the control signal of the controller 40, it is possible to extinguish a light only in an area in which a vehicle which VA approach exists, as shown in Figure 4, so that it is possible to prevent dazzling the approaching vehicle VA.
    As shown in Fig. 4, the light L3 from the second light source group 15 is scattered to form a light source image extending further in the upper and lower direction than in the direction right and left and is projected to the front of the fire. That is, the light source image of the second light source group 15 can form a rectangular (linear) light distribution pattern extending further in the upper and lower direction than in the right direction and left. The linear light distribution pattern has a size of 5 or more, which is a ratio of a width in a forward and a backward direction to a width in the right and left direction, when a width of the vehicle in the right and left direction is set to 1, for example. With regard to the format of the linear light distribution pattern Pr, the ratio of the width in the forward and backward direction over the width in the right and left direction is more preferably 1: 10 or more. As a result, for example, the linear light distribution pattern Pr can illuminate a range of 10 m to 100 m in front of the vehicle. When a vertically long linear light distribution pattern having a size larger than the format illustrated above is required, it is possible to cope with the requirement by increasing the format of the light source image, in addition to a method of changing a magnification of the light source image of the projection lens 20. For example, when the width of the vehicle in the right and left direction is set to 1, the image format of light source, which is to be formed by the light from the light emitting diode configuring the second light source group 15, i.e. the ratio of the width in the upper and lower direction over the width in the direction right and left, can be set to 1.5 to 5, for example. As a method of changing the size of the light source image, the above format may be implemented by one form of the light emitting diode of the second light source group 15 or by arranging a plurality of light emitting diodes in parallel. .
    At the same time, the second light source group 15 may be configured by two light emitting diodes and two linear light distribution patterns Pr may be formed by the two light emitting diodes. Thus, as shown in Figure 4, it is possible to draw two parallel lines corresponding to a width of the vehicle on the road surface. The vehicle light 1 may also be respectively mounted on the right and left headlights of the vehicle and the linear light distribution patterns Pr may be formed to draw two lines through the respective lights 1.
    As described above, according to the illustrative embodiment, the vehicle light 1 comprises the first light source group 12 for forward lighting, the second light source group For a road surface pattern, the projection lens 20 through which the lights emitted by the first light source group 12 and the second light source group 15 must pass, and the mask 30 disposed between the first group of the light source 12 and the second light source group 15 and the projection lens 20 so that the light L from the first light source group 12 and the light L from the second light source group 15 do not do not intersect each other before entering the projection lens 20. The light distribution control function of the first zone 20A of the projection lens 20 and the distraction control function light emission from the second zone 20B are different from each other. According to this configuration, since it is possible to form the light distribution pattern for the forward illumination Ph and the light distribution pattern for the road surface pattern Pr with a single unit, it is possible to save space while satisfying both forward lighting and road surface layout functions. Likewise, the mask 30 is provided between the light source unit 10 and the projection lens 20 so that the light L1 from the first light source group 12 and the light L3 from the second source group light 15 do not intersect each other before entering the projection lens 20. Therefore, it is possible to prevent an unexpected light distribution, which is caused when the light of the first source group of light 12 is incident on the second zone 20B of the projection lens 20 or the light of the second light source group 15 is incident on the first zone 20A of the projection lens 20.
    In addition, in the illustrative embodiment, since the exit surface 20b of the projection lens 20 has a non-spherical outer shape, the position of the rear focal point fl of the first zone 20A and the position of the rear focal point f2 of the second zone 20B are different from each other. For this reason, it is possible to obtain the clear light distribution patterns Ph, Pr by providing the first light source group 12 mounted on the printed circuit 11 in the vicinity of the rear focal point f1 of the first area 20A, and positioning the second light source group 15 in the vicinity of the rear focal point f2 of the second area 20B.
    FIG. 5 shows an example where the vehicle light of the illustrative embodiment is mounted on a vehicle.
    As shown in Fig. 5, a vehicle V has a pair of SOL, 50R headlights disposed on right and left sides of the front thereof. For example, the vehicle light 1 having the two functions of distributing traffic light and road surface pattern according to the first illustrative embodiment and a light for the dipped beam 55 configured to form a distribution. Low beam light are mounted in the right headlight 50R. Furthermore, a fire for the low beam 55 and a fire for the high beam 57 configured to form a distribution of high beam light are mounted in the left headlight SOL. In this way, the multi-purpose vehicle light 1 having high beam and road surface features is mounted in any of the left and right headlights SOL, 50R, so that it is possible to miniaturize the headlights 50L, 50R, compared to the prior art where a fire for high beam and a fire for the road surface layout are provided separately. Similarly, the fire for the low beam 55 and the fire for the high beam 57 are mounted in the lighthouse (the left headlight 50L in this example) in which the vehicle light 1 is not mounted. The left headlamp 50L therefore satisfies the required light intensity of the traffic light distribution.
    At the same time, a pivot mechanism configured to rotate a light distribution direction of the vehicle light 1 in the left and right direction can be provided and the pivot mechanism can be configured to mechanically rotate the fire. of vehicle 1, so that it is possible to move the light distribution direction (the direction of the optical axis Ax of the projection lens 20) in the right and left direction. It is thus possible to arbitrarily change the lighting directions of the lights intended to form the light distribution pattern for the high beam Ph and the linear light distribution configuration Pr. For this reason, for example, it is possible to plot the linear light distribution pattern Pr on the road surface to a direction in which a target such as a pedestrian is detected.
    Figures 6 and 7 show light distributions of light distribution patterns projected on a virtual screen provided in front of the vehicle light 1 and formed by the vehicle light 1. Figure 6A shows a lighting distribution on the virtual screen of a light distribution pattern, which is formed by the light from the first light source group when the high reflectivity processing has not been performed for the mask, and Fig. 6B shows a light distribution on the virtual screen of a light distribution pattern, which is formed by the light from the first light source group when the high reflectivity processing has been performed for the mask. Fig. 7A shows a light distribution on the virtual screen of a light distribution pattern, which is formed by the light from the second light source group when the high reflectivity processing has not been performed for the mask, and FIG. 7B shows a light distribution on the virtual screen of a light distribution pattern, which is formed by the light from the second light source when the high reflectivity processing has been performed for The mask.
    In the illustrative embodiment, the low reflectivity processing has been performed for the lower surface 31 and the upper surface 32 of the mask 30. The invention is however not limited thereto. For example, the high reflectivity processing such as vapor phase metal deposition can be performed for the lower surface 31 and the upper surface 32 of the mask 30. In this case, the light emitted by the first light source group 12 and reflected on the lower surface 31 of the mask 30 is incident on the first area 20A of the incident surface 20a of the projection lens 20. Thus, in the light distribution pattern for the high beam shown in Fig. 6B, which is obtained when the high reflectivity processing has been performed, the range of the light distribution can be widened downward, compared to the light distribution pattern for the high beam shown in Fig. 6A, which is obtained when the High reflectivity treatment was not performed. In addition, the light emitted by the second light source group 15 and reflected on the upper surface 32 of the mask 30 is incident on the second area 20B of the incident surface 20a of the projection lens 20. Thus, in the configuration of light distribution for the road surface pattern shown in Fig. 7B, which is obtained when the high reflectivity processing has been performed, the range of the light distribution can be widened downward, compared to the distribution pattern of the light distribution pattern. light for the road surface pattern shown in Fig. 6A, which is obtained when the high reflectivity processing has not been performed. On the other hand, the lower surface 31 of the mask 30 can be subjected to the high reflectivity treatment and the upper surface 32 can be subjected to the low reflectivity treatment. Alternatively, the treatments can be performed in an inverted manner.
    Fig. 8 is a vertical sectional view showing a schematic structure of a vehicle light according to a first modified embodiment of the illustrative embodiment.
    As shown in Fig. 8, a vehicle light LA of the first modified embodiment comprises a light source unit 10A having a printed circuit 11A, the first light source group 12 and the second source group of 15. The printed circuit board IIA is folded in the form of stairs in the upper and lower direction of the fire, and has a first surface 11A1 and a second surface 11A2 continuously bent from the first surface 11A1 in the rear direction of the fire. The second light source group 15 is mounted on the first surface 11A1, and the first light source group 12 is mounted on the second surface 11A2. In the vehicle light 1A, the light emitting surface of the second light source group 15 is provided in the vicinity of the rear focal point f2 of the second area 20B of the projection lens 20. On the other hand, the surface the light source of the first light source group 12 is positioned on a rear side with respect to the rear focal point f1 of the first zone 20A of the projection lens 20.
    In the illustrative embodiment, as shown in FIG. 4, the light distribution pattern P having a substantially quadrangular shape is formed by the light L1 from each light emitting diode of the first source group of the light source. light 12 aligned in the right and left direction, and the plurality of light distribution patterns P having a substantially quadrangular shape is provided in parallel in the right and left direction, so that the light distribution pattern for the light of Ph route is formed. For this reason, a low light portion (called dark line) may be formed at a limit of the respective light distribution patterns P.
    On the other hand, as the modified embodiment shown in Fig. 8, when the first light source group 12 is provided on the rear side with respect to the rear focal point f1 of the first area 20A of the projection lens 20, a outer peripheral portion of the light distribution pattern P having a substantially quadrangular shape is broadened by a spreading effect caused by defocusing, so that it is possible to make the limit of each light distribution pattern P minus obvious.
    Fig. 9 is a vertical sectional view showing a projection lens according to a second modified embodiment of the illustrative embodiment.
    An exit surface 120b of a projection lens 120 shown in Fig. 9 has a linear non-transparent area 120C between a first area 120A through which light from the first light source group is to pass and a second area 120B to through which light from the second light source group must pass. The non-transparent area 120C is preferably formed as a vapor deposition surface on which a reflective material such as a metallic film is deposited in the vapor phase. The light incident on the non-transparent area 120C thus does not escape outside the exit surface 120b. For this reason, it is possible to prevent an unexpected light distribution, which is caused by incident light on a boundary between the first zone 120A and the second zone 120B.
    At the same time, the non-transparent area 120C may be provided on an incident surface 120a, not the exit surface 120b of the projection lens 120.
    Fig. 10 is a vertical sectional view showing a projection lens according to a third modified embodiment of the illustrative embodiment.
    As shown in FIG. 10, instead of the one-piece projection lens 20 shown in FIG. 1 and the like, a first projection lens 220A through which light from the first light source group 12 must pass and a second area 220B through which light from the second light source group 15 is to pass may be configured as separate projection lenses spaced with a predetermined interval. In this case, a lower surface 220A1 of the first projection lens 220A and an upper surface 220B1 of the second projection lens 220B can be formed with light-stopping surfaces composed of vapor-deposited metal surfaces, by example. In this way, the first projection lens 220A and the second projection lens 220B are provided separately, so that it is possible to easily design appropriate lens shapes so as to obtain the light distributions for illumination towards the front and the road surface layout. Also, since the first projection lens 220A and the second projection lens 220B are provided spaced apart, it is possible to prevent unexpected light distribution, which is caused by incident light on a boundary between the lenses. projection 220A, 220B.
    At the same time, the first projection lens 220A and the second projection lens 220B are not limited to the above configuration shown in Fig. 10 where they are provided with a predetermined interval. For example, the lower surface 220A1 of the first projection lens 220A and the upper surface 220B1 of the second projection lens 220B may be in contact with a light stopping surface consisting of a metal vapor deposition surface or equivalent that is interposed.
    Fig. 11 is a vertical sectional view showing a projection lens according to a fourth modified embodiment of the illustrative embodiment, and Fig. 12 is a sectional view taken along line AA of Fig. 11. .
    As shown in Fig. 11, an incident surface 320a of a projection lens 320 is formed with a plurality of diffusion stages, or steps, cylindrical SI (an example of the first diffusion stage) arranged in parallel along the upper and lower direction of the fire. Also, as shown in Fig. 12, an exit surface 320b of the projection lens 320 is formed in a first zone 320A with a plurality of cylindrical diffusion bearings S2 (an example of the second diffusion plateau) disposed in parallel along the right and left direction of the fire.
    Like this, in the first zone 320A of the projection lens 320, the incident surface 320a is formed with the cylindrical bearings SI arranged in parallel in the upper and lower direction, and the exit surface 320b is formed with the cylindrical bearings S2 disposed in parallel in the right and left direction. Similarly, in a second zone 320B of the projection lens 320, the incident surface 320a is formed with the cylindrical bearings SI arranged in parallel in the upper and lower direction but the exit surface 320b is not formed with the bearing broadcast or equivalent. Furthermore, the diffusion bearing, which must be formed on the projection lens 320, is not limited to the cylindrical shape and may be a bearing having a shape whose tangential lines are continuous (an irregular shape having a continuity of tangent) or a bearing having a shape whose curvatures are continuous (an irregular shape having a continuity of curvature). In addition, the diffusion bearing is not limited to the curved surface and may have a triangular shape or equivalent, for example.
    In the fourth modified embodiment, since the incident surface 320a of the projection lens 320 is formed with the cylindrical bearings SI arranged in parallel along the upper and lower direction of the fire, the light L5 from the first group light source 312 is emitted outside the exit surface 320b in the form of a scattering light which diffuses in the upper and lower direction through the cylindrical bearings SI. In addition, as shown in Fig. 12, since the exit surface 320b of the projection lens 320 is formed in the first zone 320A with the cylindrical bearings S2 arranged in parallel along the right and left direction, the light L5 from the first light source group 312 is emitted outside the exit surface 320b in the form of a scattering light which diffuses in the right and left direction. The light source image of the first light source group 312 thus passes through the projection lens 320, thereby extending equally in the upper and lower direction and in the right and left direction.
    In addition, as shown in FIG. 12, the light L6 emitted by the second light source group 315 is emitted outside the exit surface 320b, in the form of a diffusion light. which diffuses in the upper and lower direction through the cylindrical bearings SI formed on the incident surface 320a of the projection lens 320. However, since the cylindrical bearings or equivalent are not formed in the second zone 320B of the exit surface 320b of the projection lens 320, the light L6 from the second light source group 15 is emitted outside the exit surface 320b, in the form of a substantially parallel light, without diffusing in the right and left direction . The light source image of the second light source group 315 thus passes through the projection lens 320, thereby extending further in the upper and lower direction than in the right and left direction.
    According to the configuration of the fourth modified embodiment, as the illustrative embodiment, it is possible to form the light distribution pattern for the forward illumination Ph extending equally in the right and left direction and in the upper and lower direction through the light L5 from the first light source group 312 and the light distribution pattern for the road surface pattern Pr extending further in the upper direction and lower than in the right and left direction by the light L6 from the second light source group 315 with a single unit.
    In the fourth modified embodiment, the incident surface 320a of the projection lens 320 is formed with the cylindrical bearings SI configured to diffuse light L5 from the first light source group 312 and light L6 from the second light source group 15 so as to further extend the lights in the upper and lower direction of the fire than in the right and left direction of the fire. The invention is however not limited to this. For example, the incident surface 320a of the projection lens 320 may not be provided with bearings and the exit surface 320b of the projection lens 320 may be formed in the second zone 320B with diffusion bearings (e.g. cylindrical bearings) arranged in parallel in the upper and lower direction. The exit surface 320b of the projection lens 320 is thus formed in an upper half portion, which is the second zone 320B, with the cylindrical bearings arranged in parallel in the upper and lower direction and is formed in a lower half portion which is the first zone 320A, with the cylindrical bearings S2 arranged in parallel in the right and left direction. In this case, the light source image of the second light source group 315 forms the light distribution pattern extending further in the upper and lower direction than in the right and left direction, as the third embodiment. modified, and the light source image of each light emitting diode of the first light source group 312 forms the light distribution pattern extending further in the right and left direction than in the upper and lower direction, unlike of the third modified embodiment.

The diffusion bearing S3 (an example of the third diffusion stage) is constituted by a plurality of bearings cylindrical arranged in parallel in the right and left direction, for example. The additional lens 130 thus serves as a diffusion lens in the right and left direction.
    In the fifth modified embodiment, the incident light L7 on the additional lens 130 of the first light source group 112 is emitted from the exit surface 130b of the additional lens 130, as substantially parallel light, in the vertical section shown in Fig. 13. Moreover, in the section in the right and left direction shown in Fig. 14, since the exit surface 130b is formed with the cylindrical bearings S3 arranged in parallel along the straight direction and left of the light, the light L7 is emitted from the exit surface 130b, in the form of a scattering light which diffuses in the right and left direction. That is, a light source image of the first light source group 112 passes through the additional lens 130, so that it becomes a light source image extending further into the light source image. right and left direction only in the upper and lower direction.
    In the fifth modified embodiment, as a projection lens (not shown), a projection lens (a diffusion lens in the upper and lower direction) having a light distribution control function for diffusing the lights from the first light source group 112 and the second light source group 115 in the upper and lower direction is preferably used. When the projection lens is used, a light source image (a horizontally long light source image extending more in the right and left direction than in the upper and lower direction) formed by the light emitted from the first group a light source 112 which has passed through the additional lens 130 passes through the projection lens, thus extending further in the upper and lower direction than in the right and left direction. That is, the light source image of the first light source group 112 passes through the additional lens 130, which is a diffusion lens in the right and left direction, and the projection lens, which is a diffusion lens in the upper and lower direction, thus forming the light distribution pattern Ph extending equally in the right and left direction and in the upper and lower direction. On the other hand, the light source image of the second light source group 115 passes through the projection lens, which is a diffusion lens in the upper and lower direction, thereby forming the light distribution pattern. Pr extending more in the upper and lower direction than in the right and left direction. According to this configuration, as the illustrative embodiment above, it is possible to form the light distribution pattern for the forward illumination Ph extending equally in the right and left direction and in the the upper and lower direction through the light source image of the first light source group 112 and the light distribution pattern for the road surface pattern Pr extending further in the upper and lower direction than in the right and left direction through the light source image of the second light source group 115, with a single unit.

The incident light L8 on the reflector 140 from the aperture 140a facing the first light source group 112 is reflected on a reflective surface 140c of the reflector 140 and is then emitted from the aperture 140b. At this time, since aperture 140b on the exit surface side has a horizontally long rectangular shape, light L8 from the first light source group 112 forms a light source image extending further into the right and left direction only in the upper and lower direction in the opening 140b.
    Although it is not shown in the sixth modified embodiment also, a projection lens (a diffusion lens in the upper and lower direction) having cylindrical bearings arranged in the upper and lower direction and formed on any of an incident surface and an exit surface thereof may be used. When the projection lens is used, the light emitted from the first light source group 112 and passed through the reflector 140 and the light from the second light source group 115 diffuse in the upper and lower direction. Therefore, it is possible to obtain the light distribution pattern for the forward illumination Ph and the light distribution pattern for the road surface pattern Pr by combining the reflector 140 and the projection lens.

The incident surface 150a is larger than the light emitting surfaces of the respective light emitting diodes of the first light source group 112, and the exit surface 150b has a horizontally long rectangular shape (wider in the right and left direction than in the upper and lower direction). The light emitted by the first light source group 112 and incident on the incident surface 150a of the light guide member 150 passes through an interior of the light guide member 150 and is then transmitted from the outlet surface 150b. At this time, since the exit surface 150b has a horizontally long rectangular shape, the light from the first light source group 112 forms a light source image extending further in the right and left direction than in the light source image. upper and lower direction on the exit surface 150b.
    In addition, a light guiding element 160 is provided in the vicinity of the second light source group 115.

The light emitted by the second light source group 115 and incident on the incident surface 160a of the light guide member 160 passes through an interior of the light guide member 160 and is then emitted from from the exit surface 160b. At this time, since the exit surface 160b has a vertically rectangular shape, the light from the second light source group 115 forms a light source image extending further in the upper and lower direction than in the right and left direction on the exit surface 160b.
    According to this configuration, light from the first light source group 112 may be incident on the projection lens, in the form of a light source image extending further in the right and left direction than in the upper and lower direction, and the light from the second light source group 115 may be incident on the projection lens, in the form of a light source image extending further in the upper and lower direction than in the right and left direction.

The cylindrical lens 170 is configured as a lens that has a curvature of a convex lens in the horizontal direction and has no curvature in the vertical direction. Thus, only the horizontal direction of the cylindrical lens 170 acts as a plano-convex lens, so that the light is refracted in a direction of focus of the light. When the cylindrical lens 170 is provided in the vicinity of the second light source group 115, for example, the light from the second light source group 115 is focused in the right and left direction, so that light can form a light source. a larger light source image in the upper and lower direction than in the right and left direction in a stage where light has passed through the cylindrical lens 170. In addition, when a cylindrical lens whose direction is turned from the direction of the cylindrical lens 170 around the optical axis of the fire of 90 ° is provided in the vicinity of each light-emitting diode of the first light source group 112, it is possible to form a light source image extending further into the left and right direction only in the upper and lower direction at the level of a stage where light has passed through the cylindrical lens. For this reason, it is possible to obtain the desired light distribution patterns for forward lighting and road surface layout by combining the cylindrical lens and the projection lens.
    At the same time, a toric lens can also be used in place of the cylindrical lens.
