    [0001] This disclosure relates to a vehicle light forming a plurality of light distributions. A fire of this type comprises a first fire unit configured to form mainly a low beam and a second fire unit configured to primarily form a high beam, to form two types of light distributions, for example, a low beam light distribution and a high beam light distribution. With the current demand for reduced footprint, a fire is known that includes first and second light sources that are disposed above and below a plate-shaped support member to share a projection lens. so as to form a plurality of light distributions with a single fire unit (see, for example, Japanese Patent Laid-Open Publication No. 2005-108554).
    [0002] The structure described in Japanese Patent Application Laid-open No. 2005-108554 has a problem, the light sources are close to each other so that the fire can be easily saturated with heat generated at from sources of light. The present disclosure has been proposed to solve the problems described above and must provide a vehicle light that forms a plurality of light distributions with a single fire unit, from which light sources can be arranged to be spaced apart. others. In order to solve the problem described above, one aspect of the present disclosure provides a vehicle light comprising: a first lens that has a positive refractive power on a front surface and a back surface thereof; a second lens which is positioned behind the first lens and which comprises a plurality of positive refractive zones each having a positive refractive power; and a plurality of light sources which are respectively disposed in a plurality of locations, behind the second lens, which respectively correspond to the plurality of positive refractive zones of the second lens.
    [0003] In other words, the second lens converges light from each of the focal points of the plurality of positive refractive zones to different areas of the first lens. The first lens converges light from the second lens and emits light in the form of parallel light. In this aspect, the light emitted from each of the focal points of the plurality of positive refractive zones of the second lens is caused to converge by the second lens to a positive refractive area on which the light is incident. , and is distributed to different areas of the first lens. The light is then caused to converge by the first lens to be emitted outwardly in the form of parallel light. In this aspect, since the light sources are disposed near the focal points of the positive refraction zones, the light sources may be provided to be spaced from each other. In addition, a single fire unit can form a plurality of light distributions depending on the number of positive refractive zones of the second rear lens. The second lens is in the form of an integrated body comprising a plurality of convex front surface lenses 30 which are formed integrally, and a front surface of the first lens may be formed by a substantially convex surface having a continuous curvature vertically and transversely.
    [0004] The positive refractive zones of the second lens may have an upper zone and a lower zone. The light sources may be a dipped beam light source positioned to correspond to the upper zone and a road light source positioned to correspond to the lower zone. Each of the first lens and the second lens may have a flange and the flange of the first lens and the flange of the second lens may both be positioned and secured to a support member of the light sources via a lens support member configured to secure the two flanges. According to the present disclosure, it is possible to provide a vehicle light in which a single fire unit forms a plurality of light distributions, and light sources can be arranged to be spaced apart from each other. The foregoing summary is illustrative only and is not intended to be limiting in any way.

Exemplary embodiments of the present disclosure will be described hereinafter with reference to the accompanying drawings. (First exemplary embodiment) FIG. 1 is a front view of a light 1 according to a first exemplary embodiment. Fig. 2 is a vertical sectional view of the light 1 according to the first exemplary embodiment (a sectional view along line II-II of Fig. 1). The light 1 is a headlight installed in the left or right side of a front part of a vehicle. The arrow LR indicates a left-right direction when the light 1 is seen from the front side, the UD arrow indicates a high-low direction when the light 1 is seen from the front side, and the arrow FB indicates a forward direction. back when the fire 1 is seen from the front side. The fire 1 comprises a fire chamber which is defined by a box-shaped fire body 2 having an opening, and a cabochon 15 3 fixed to the opening. The cabochon is formed of transparent resin, glass, or equivalent. In the fire chamber are arranged a fire unit 5, a fire support 6, and an extension 7. The extension 7 is positioned in front of the fire unit 5 and has an opening to allow light emitted to from the fire unit 5 to move towards the front side of the fire. The fire support 6 has four (4) corners, including three corners fixed to the fire body 2 by adjusting screws 8, and allows an optical axis of the fire unit 5 to be adjusted vertically and transversely. . The fire unit 5 comprises a first lens 12, a second lens 14, a low beam light source 16 and a low beam reflector 17 for a passing beam, a mask 15, a source of traffic light 18 and a traffic light reflector 19 for a driving beam, and a heat sink 20, in that order from the front side. The heat sink 20 is a metal block made by casting aluminum and serves as a support member for elements of the fire unit 5. A thermal radiation fin (not shown) is formed on the surface back of the heat sink 20 so as to allow heat from the dipped beam light source 16 and the road light source 18 to be radiated into the space in the chamber of traffic light. The heat sink 20 is attached to the front surface of the fire support 6. The description will first be given to the two lenses, which form a main part of this disclosure, i.e. the first and second lenses 12 and 14. Figures 3A and 3B are views illustrating light beams formed by the fire unit 5 according to the first exemplary embodiment. Figure 3A is a vertical sectional view of the first and second lenses 12 and 14 (a sectional view in the up-down direction). Figure 3B is a horizontal sectional view of the first and second lenses 12 and 14 (a sectional view in the left-right direction). The arrows in Figures 3A and 3B represent the beams of light. The first lens 12 is a plano-convex lens having a front surface 12f with a continuous curvature vertically and transversely and a flat rear surface 12b. The first lens 12 has a positive refractive power to converge incident light from the rear surface 12b and emit light from the front surface 12f as parallel light. Furthermore, the front surface 12f can have 30 different curvatures in the up-down direction and in the left-right direction (non-symmetrical in rotation). In the description, the term "back surface" for a lens is understood to mean the surface through which light enters the lens, and "front surface" for a lens means the surface through which light emerges from the lens. The second lens 14 is positioned behind the first lens 12. The second lens 14 comprises two (2) positive refractive zones of an upper zone 14u and a lower zone 14d, which have a positive refractive power to converge the incident light from the back surface and emit light from the front surface. Each of the upper zone 14u and the lower zone 14d has a shape obtained by dividing a plano-convex lens into two parts. The upper zone 14u has a convex front surface 14uf which has a continuous curvature vertically and transversely so that the upper end 15 of the upper zone 14u becomes thicker, and a flat rear surface 14ub. This upper zone 14u therefore forms a first convex front surface lens. The lower zone 14d has a convex front surface 14df which has a continuous curvature vertically and transversely so that the lower end of the lower zone 14d becomes thicker, and a flat rear surface 14db. This lower zone 14d therefore forms a second convex front surface lens. Therefore, in the second lens 14, the incident light on the upper area 14u is subjected to a refractive power which causes the light to converge upward, and the light incident on the lower area 14d is subjected to a refractive power which makes converge the light down. The upper zone 14u and the lower zone 14d are interconnected by a connecting portion 14c to form an integrated lens. The connecting portion 14c may have a flat plate shape having no lens characteristics, but may have an edge with a discontinuous curvature.
    [0006] The second lens 14 has upper and lower rear focal points, which are symmetrical with respect to each other about the optical axis Axl of the first lens 12. That is to say, the second lens 14 has lens 14 has a rear focal point A of the upper zone 14u and a rear focal point B of the lower zone 14d (hereinafter simply referred to as the "focal point A" and the "focal point B"). The second lens 14 converges, in its upper zone 14u, the light emitted from the focal point A to an upper zone 12A of the first lens 12 and converges, in its lower zone 14d, the light emitted from the point focal point B to a lower zone 12B of the first lens 12 to distribute upwards and downwards the lights 15 emitted from the focal points A and B. The first lens 12 also converges the incident light from the upper zone 12A for emitting light towards the front side of the lamp in the form of parallel light, and also converging the incident light from the lower area 12B to emit light towards the front side of the lamp in the form of parallel light . In addition, light source images of the focal points A and B formed on a rear focal plane of the first lens 12 are projected towards the front side of the lamp in the form of inverted images. The periphery of the light sources will then be described, but the light sources are not particularly limited with respect to their type in the present disclosure. In addition to the light-emitting diodes 30 described below, an incandescent lamp, a discharge lamp, or other diodes may be used for the light sources. In addition, the following description relates to a suitable example in a case where it is intended to form two types of light distributions, for example, a passing beam and a driving beam using the first and second lenses 12 and 14 which form a main part of this disclosure.
    [0007] As illustrated in FIG. 2, the low beam light source 16 is a white light emitting diode having a rectangular light emission surface. The cross-fire light source 16 is positioned behind the focal point A in correspondence with the upper zone 14u, and fixed on the upper surface of the heat sink 20 with the light-emitting surface facing upwards. The dipped beam reflector 17 has a curved surface shape of a generally elliptical shape, and is attached to the upper surface of the heat sink 20 so that the first focal point is at the center of light emission. The reflector 17 reflects the light emitted from the low beam light source 16 towards the front side of the light. The mask 15 has an upper end edge in a shape capable of partially obscuring the light that is emitted from the low beam light source 16 and reflected by the low beam reflector 17. The mask 15 is integrated in the heat sink 20 so that the upper end edge is located at the focal point A. The road light source 18 may include eleven (11) white light emitting diodes 30 each having a light emitting surface. rectangular light. The light emitting diodes in the traffic light light source 18 are disposed on the left and right sides of the focal point B at equal intervals in correspondence with the lower zone 14d, and 3032778 attached to the front surface of the heat sink 20 with the light emitting surfaces facing forward. Each white light-emitting diode in the traffic light light source 18 is independently controlled to be turned on / off by an ON / OFF control circuit (not shown) and an electronic light distribution control unit (not shown). ). The road light reflector 19 has a flat surface or a parabolic curved surface and is attached to the front surface of the heat sink 20 to extend below the row of white light emitting diodes in the light source of fire 18. The traffic light reflector 19 reflects the light emitted from the light source 18 towards the front side of the light. The description will relate to light distributions formed by the fire unit 5 having the configuration as described above. Fig. 4 is a view illustrating light distribution patterns obtained by the light 1 according to the first exemplary embodiment. Fig. 4 shows a virtual vertical screen positioned at a position 25 m from the front side of a vehicle, and illustrates a case where the low beam light source 16 and the high beam light source 18 are all both lit. When the light source 16 is turned on, a passing light light distribution pattern PL having clipping lines CL1 and CL2 is formed in a zone mainly below the line H-H of the virtual vertical screen. Since the shape of the passing beam light distribution pattern PL is well known, the description thereof will be omitted. When all the white light-emitting diodes in the traffic light light source 18 are on, a road fire light distribution pattern PH is formed by the combination of eleven (11) rectangular segments Ph, which are images projecting the white light-emitting diodes into the light source 18, in an area mainly above the line HH of the virtual vertical screen. The white light-emitting diodes in the traffic light light source 18 may be independently turned on / off as described above.
    [0008] Thus, although not illustrated, the road light distribution pattern PH may form an adaptive driving beam (ADB) to extinguish some of the Ph segments in Fig. 4, when the electronic control unit The light distribution detector detects the presence of other objects from, for example, an approaching vehicle sensor, a pedestrian sensor or the like mounted, for example, in a vehicle. The description will then be given to an exemplary method of fixing two (2) lenses 12 and 14 to suitably implement the function of the fire unit 5. FIG. 5 is a perspective view of the Fire unit 5 according to the first exemplary embodiment, and Fig. 6 is an exploded perspective view of a portion of the fire unit 5 according to the first exemplary embodiment. A pair of flanges 121 are formed integrally with the first lens 12, the flanges 121 extending from the left and right peripheral edges of the first lens 12 to the left and right directions, respectively. Each of the flanges 121 has through holes 122 open at two points, wherein the vertical distance between two points in one flange 121 is equal to that in the other flange 121. A positioning hole 123 is formed between the through holes. 122 in each of the flanges 121. Similarly, a pair of flanges 141 is formed integrally with the second lens 14, the flanges 141 extending from the left and right peripheral edges of the first lens 14 towards the left and right directions, respectively. Each of the flanges 141 has through holes 142 open at two points in which the vertical distance between two points in one flange 141 is equal to that in the other flange 141. A positioning hole 143 is formed between the through holes 142 in each of the flanges 141. The length of the flanges 141 in the left and right directions is shorter than that of the flanges 121 of the first lens 12. The two lenses 12 and 14 are positioned and fixed on the heat sink 20 by a pair of lens support members 40. Each of the lens support members 40 has a first stop portion 42, a second stop portion 44, and an arm portion 46. The second stop portion 44 has a flat plate, and includes mounting holes 441 on the vertical front end surface thereof which are aligned with the through holes 142 of the second lens 14. A positioning pin 442 is formed at a position corresponding to the positioning hole 123 between the mounting holes 441. The second lens 14 is first positioned by the positioning hole 123 and the positioning pin 442, and then fixed on the vertical front end surface by screw assemblies (not shown) through through holes 142 and mounting holes 441.
    [0009] The first abutment portion 42 is positioned outside the second abutment portion 44 and has a flat plate shape extending forwardly from the second abutment portion 44. The first abutment portion 42 includes mounting holes 421 on the vertical front end surface thereof aligned with the through holes 122 of the first lens 12. A positioning pin 422 is formed in a position corresponding to the positioning hole 123 between the The first lens 12 is first positioned by the positioning hole 123 and the positioning pin 422, and then affixed to the vertical front end surface by screw assemblies (not shown). through the through holes 122 and the mounting holes 421. The arm portion 46 extends rearwardly from the upper end surface of the first and second abutment portions 42 and 44, and is tightened by screw on the heat sink 20 using the mounting holes 461 formed at two points on the back side of the arm portion 46 and a locating hole 462 to be engaged with a positioning pin (not shown) protruding towards the top from the heat sink 20. As described above, each of the first lens 12 and the second lens 14 has on its outer peripheral edge a pair of flat flanges 121 or 141 having a shape and the lens support members 40 have stepped portions, the number of which corresponds to the number of lenses, in the front-to-back direction. Each of the first lens 12 and the second lens 14 is fixed and positioned as follows: the flanges 121 of the first lens 12 are brought into contact with and fixed on the vertical front end surfaces of the outer tiered portions (the first stop portions 42), and, within the flanges 121, the flanges 141 of the second lens 14 are brought into contact with and attached to the vertical front end surfaces of the stepped portions 5 (the second stop portions 44) which are formed to have a length to be shorter than the outermost stepped portions in the front-to-back direction. Then, the lens support members 40 are attached to the heat sink 20, on which the light sources 16 and 18 are fixed, so that the light sources 16 and 18, the first lens 12, and the second lens 14 are positioned. On the other hand, the lengths of the arm portions 45 and the first and second stop portions 42 and 44 in the front-rear direction are suitably designed based on the positions of the focal points of the first and second lenses 12 and 14. As described above, according to the fire unit 5, light emitted from the focal points A 20 and B of the second lens 14 is caused to converge on upper and lower areas 14u and 14d of the second lens 14, respectively, for distribution to the upper and lower regions 12A and 12B of the first lens 12, respectively, and further to converge by the first lens 12 to be projected as parallel light. When the light sources are arranged in effective positions in the fire unit 5, the light sources are arranged near the rear focal points A 30 and B of the upper and lower areas 14u and 14d. Thus, in the fire unit 5, the light sources may be provided to be spaced from each other. In addition, while the fire unit 5 is a single fire unit configured to project the low beam light source 16 and the road light source 18 using a single projection lens (the first lens 12), the fire unit 5 can form two types of light distributions, i.e., the low beam light distribution pattern PL formed through the upper zone 14u of the second lens 14 and the road fire light distribution pattern PH formed through the lower zone 14d of the second lens 14.
    [0010] In addition, since both lenses 12 and 14 are provided in the front-to-back direction, the fire resembles a single bulb fire which has only the first lens 12 disposed at the most forward position relative to the side. before the fire and has a continuous surface, when the fire is extinguished (see Figure 1). Thus, fire is also appropriate for the design of a fire. In addition, because of the refractive power of the foremost forward lens 12, the structure behind the first lens 12 is barely visible. In addition, since both lenses 12 and 14 are provided in the front-to-back direction, the refractive power can be dispersed over the lenses so that each of the lenses can be formed to be thin. Thus, the time required for injection molding of the lenses can be reduced. In addition, since the flanges 121 and 141 are formed on the first and second lenses 12 and 14 and the first and second lenses 12 and 14 are positioned and fixed on the heat sink 20, which is a support element for the sources of 16 and 18, by the lens support members 40, the first and second lenses 12 and 14 may be fixed in a state where the central axis of the first lens 12 (ie the axial axis Axl) and the central axis of the second lens 14 (the axis which passes through the center of the entire second lens 14, and in the present exemplary embodiment, the axis Ax2, around which the Rear focal point A of the upper zone 14u and the rear focal point B of the lower zone 14d are vertically symmetrical with respect to each other) are coaxially aligned with each other. (Second exemplary embodiment) The fire unit 5 according to the present disclosure can form a larger number of light distributions depending on the number of positive refractive zones of the second rear lens 14. The description will be made on this configuration. Fig. 7 is a vertical sectional view of a light 1 according to a second exemplary embodiment. Moreover, elements, which are identical to the elements of the first exemplary embodiment, will be designated by the same references, and the description thereof will be omitted.
    [0011] The first lens 12 is identical to that of the first exemplary embodiment. The second lens 14 has three (3) positive refractive zones that have positive refractive power to converge incident light from the back surface, and emit light from the front surface, i.e. the upper zone 14u, a median zone 14m, and the lower zone 14d. The upper zone 14u and the lower zone 14d are identical to those of the first exemplary embodiment. The middle zone 14m is a plano-convex lens having a convex front surface 14mf with a continuous curvature vertically and transversely and a flat rear surface 14mb. The upper zone 14u, the lower zone 14d and the central zone 14m therefore form respectively a first, a second and a third convex front surface lens. The middle zone 14m converges incident light from the 14mb rear surface, and emits light from the front surface 14mf. In the present exemplary embodiment, the central axis Ax2 of the second lens 14 corresponds to the optical axis of the central zone 14m. The focal point C of the median zone 14m appears on the optical axis Axl of the first lens 12, and the focal point A of the upper zone 14u and the focal point B of the lower zone 14d appear above and below. below the Axl optical axis, respectively, so as to be symmetrical with respect to each other. The upper zone 14u and the lower zone 14d are connected by the median zone 14m, thus being in the form of an integrated lens.
    [0012] In the present exemplary embodiment, the light, which is incident on the upper zone 14u of the second lens 14 from the focal point A and is caused to converge towards the upper zone 12AA of the first lens 12, the light, which is incident on the lower zone 14d of the second lens 14 from the focal point B, is caused to converge on the lower zone 12BB of the first lens 12, and the light, which is incident on the central zone 14m of the second lens 14 from the focal point C, is caused to converge on the central area 12CC of the first lens 12, so that the light is distributed to the upper zone, the lower zone, and the zone central of the first lens 12 and emitted from the first lens 12 to the front side of the light in the form of parallel light. The description will be directed to a peripheral example of suitable light sources for the fire unit 5 in the case where the present exemplary embodiment is adopted. The following description relates to an example of a case in which three types of light distributions are to be formed, for example a passing beam, a driving beam, and a beam. additional.
    [0013] The dipped beam light source 16 which forms the dipped beam, the dipped beam reflector 17 and the mask 15 are identical to those of the first exemplary embodiment, and the attachment positions of these they are also identical to those of the first exemplary embodiment. While the road light source 18 which forms the driving beam and the traffic light reflector 19 are also identical to those of the first exemplary embodiment, and the mounting positions thereof are also identical to those of the first exemplary embodiment, the white light-emitting diodes in the traffic light light source 18 are disposed on the left and right sides of the focal point C of the central zone 14m.
    [0014] The present exemplary embodiment further comprises an additional light source 26 and a reflector 27 for the additional light source 26. The additional light source 26 is, for example, a white light emitting diode having a surface area of 25. rectangular light emission. The additional light source 26 is positioned behind the focal point B of the lower zone 14d, and fixed on the bottom of the heat sink 20 with the light-emitting surface facing downwards. The additional reflector 27 has a generally elliptical curved surface, and is attached to the bottom of the heat sink 20 so that the first focal point is at the light emitting center of the additional light source 26. The reflector The additional light 27 reflects the light emitted from the additional light source 26 towards the front side of the light. Light distributions formed by the fire unit 5 will be described. Fig. 8 is a view illustrating light distribution patterns obtained by the fire according to the second exemplary embodiment. Figure 8 also shows a virtual vertical screen positioned at a position 25 m from the front side of a vehicle, and illustrates a case in which the low beam light source 16, the high beam light source 18 and the additional light source 26 are all on. In the present exemplary embodiment, in addition to the passing beam light distribution pattern PL by switching on the low beam light source 16 and the road fire light distribution pattern PH by turning on the source 19, an additional PH2 road light distribution pattern of an oval shape is formed around the crossing point of the HH line and the VV line by turning on the additional light source 26 to improve the visibility of a remote location. As described above, the fire unit 5 is a fire unit 25 that projects the low beam light source 16, the road light source 18 and the additional light source 26 to the light source. by means of a single projection lens (the first lens 12), and can form three types of light distributions, that is, the low beam light distribution pattern PL formed via the upper zone 14u, the road fire light distribution model PH formed via the lower zone 14d, and the additional road light distribution pattern PH 3032778 formed through the zone median 14m. As described above, the present disclosure can form light distribution patterns 5 in the same number as the positive refraction zones formed in the second rear lens 14. In the exemplary embodiments described above the description has been made of the examples in which the fire unit 5 is applied to a headlamp which forms a passing beam and a driving beam. However, the fire unit 5 may be applied to a rear light which forms a plurality of light distributions such as, for example, a turn signal light and a stop light. (Modifications) The first lens 12 and the second lens 14 may be subject to the modifications described hereinafter. Figs. 9A-9C illustrate modifications of the lenses according to the present disclosure. The modification will be described based on the first exemplary embodiment. The elements, which are identical to those of the first exemplary embodiment, will be designated by the same references, and their description will be omitted. In Fig. 9A, the rear surface 12b of the first lens 12 has a continuously curved V-shaped concave portion 31, which is V-shaped recessed at the center of the vertical direction of the first lens 12 towards the surface before 12f. Therefore, the light from the focal point A of the upper zone 14u of the second lens 14 and the light from the focal point B of the lower zone 14d of the second lens 14 can more easily be distributed to the upper and lower zones of the second lens 14. the back surface 12b. In addition, since the rear surface 12b is curved, the structure behind the first lens 12 is even more difficult to see. In Fig. 9B, the front surface 12f of the first lens 12 has a slightly concave portion 32, which is slightly recessed V-shaped at the center of the vertical direction of the first lens 12 towards the rear surface 12b. The rear surface 12b includes the V-shaped concave portion 31 as described above. Therefore, the light from the focal point 10A of the upper region 14u of the second lens 14 and the light from the focal point B of the lower zone 14d of the second lens 14 can also be easily distributed to the upper and lower regions of the lens 14. the front surface 12f. As described above, the front surface 12f of the first lens 12 may have a convex surface with a continuous curvature vertically and transversely, over which a concave portion is partially formed. In this case, the slightly concave portion 32 of the front surface 12f of the first lens 12 has a negative refractive power since diffusion occurs in the slightly concave portion 32. However, the case is interpreted as being included in the scope of the present disclosure since the entire first lens 12 has a positive refractive power for convergence. In Fig. 9C, the first lens 12 is in the form of a biconvex lens. The back surface 12b has a convex surface with the continuous curvature vertically and transversely, and the front surface 12f includes the slightly concave portion 32 as described above. On the other hand, the curvature of the second lens 14 may be properly determined depending on the first lens 12 of Figs. 9A-9C.
    [0015] With respect to other modifications, the second lens 14 may not be formed as a lens (an integrated lens). That is, a lens having the function of the upper zone 14u and a lens having the function of the lower zone 14d can be positioned and fixed individually.
