[0022] Hereinafter, an embodiment of the vehicle lamp of the present application will be described based on the drawings. Furthermore, the present application is not limited to this embodiment. In addition, the constituent elements in the following embodiment include elements that can be and are easily replaced by those skilled in the art, or substantially identical elements. In the following description, each direction of front and back (front, back), up and down (upper, lower), and left and right (left, right) is the direction in a state where the vehicle lamp is installed in a vehicle, and indicates the direction when the front is viewed in a state of sitting on a driver's seat. Furthermore, in this embodiment, the up-and-down direction is parallel to the vertical direction, and the left-and-right direction is the horizontal direction.

[0023] Figure 1 is a plan view showing an example of the vehicle lamp 100 of this embodiment. Figure 2 and Figure 3 is a view showing an example of a structure of the vehicle lamp 100 viewed from the front side (front). In addition, Figure 3 shows a state where the projection lens 30 is omitted in Figure 2 . Figure 4 is a view schematically showing a structure along the A-A section in Figure 2 . Figure 5 is a perspective view showing an example of the vehicle lamp 100. Figure 5 shows a state where the vehicle lamp 100 is viewed from the back and upper side.

[0024] Figures 1 to 5The vehicle lamp 100 shown is used as a headlight for a vehicle. The vehicle lamp 100 is mounted, for example, on the left or right front of the vehicle. Hereinafter, the vehicle lamp 100 mounted on the left front of the vehicle will be described as an example. Therefore, in the vehicle lamp 100, the left side in the left-right direction is the inner side of the vehicle, and the right side in the left-right direction is the outer side of the vehicle. Furthermore, the vehicle lamp mounted on the right front of the vehicle can be configured with a structure that is symmetrical about the left and right sides of the vehicle lamp 100.

[0025] like Figure 1 As shown, the vehicle lamp 100 includes a light source 10, a reflector 20, a projection lens 30, and a heat dissipation component 40. The vehicle lamp 100 forms an illumination pattern in front of the vehicle. The vehicle lamp 100 has a so-called unilateral light distribution structure. That is, the vehicle lamp 100 forms the right side of the ADB pattern as the illumination pattern. Furthermore, the ADB pattern is formed by combining a vehicle lamp mounted on the right front of the vehicle and a vehicle lamp mounted on the left front of the vehicle. In this case, the vehicle lamp on the right front of the vehicle forms the right side portion from the center portion of the ADB pattern in front of the vehicle, and the vehicle lamp on the left front of the vehicle forms the left side portion from the center portion of the ADB pattern in front of the vehicle.

[0026] The light source 10 is, for example, a semiconductor light source such as an LED. Multiple light sources 10 are arranged in the left-right direction. Each light source 10 has a light-emitting surface 11 that emits light. When the vehicle lamp 100 is installed in a vehicle, the light-emitting surface 11 is arranged, for example, facing downwards and parallel to the horizontal plane. The light source 10 is mounted on a substrate 12. The substrate 12 is held in place by a heat sink 40. Circuits for supplying power and electrical signals to the light source 10 are formed on the substrate 12.

[0027] The reflector 20 has a first reflective portion 21 and a second reflective portion 22. The first reflective portion 21 is provided for each light source 10, for example. The first reflective portions 21 are arranged in a left-right direction corresponding to each light source 10.

[0028] The second reflector 22 reflects light from the light source 10 in a direction different from the front of the vehicle. The second reflector 22 functions as a light-dark boundary forming part for forming the ADB pattern, and also as a glare suppressing part by reflecting light in a way that prevents it from incident on the lens part 31. Detailed structures of the first reflector 21 and the second reflector 22 will be described later.

[0029] The projection lens 30 projects light reflected by the first reflecting portion 21 toward the front of the vehicle to form an irradiation pattern. The projection lens 30 is formed, for example, in a quadrangular shape as viewed from the front (front direction). Note that the shape of the projection lens 30 as viewed from the front is not limited to a quadrangular shape. The projection lens 30 is inclined rearward from the inner side of the vehicle to the outer side of the vehicle (see Figure 1 ). In addition, the projection lens 30 is inclined upward from the inner side of the vehicle to the outer side of the vehicle as viewed from the front (see Figure 2 ). The projection lens 30 has a plurality of lens portions 31. The plurality of lens portions 31 are arranged in a state of being aligned in the left-right direction. The plurality of lens portions 31 are integrally connected. Each lens portion 31 has an incident surface 31a on which light reflected by the first reflecting portion 21 is incident. In addition, the plurality of lens portions 31 have a common exit surface 31b from which light incident from each incident surface 31a is emitted.

[0030] The lens portion 31 disposed at the innermost side of the vehicle of the projection lens 30 is configured to have the least spread of the emitted light to the inner side. According to this configuration, the space in front of the projection lens 30 and on the inner side of the vehicle can be effectively used to dispose other structures, and the degree of freedom of the layout is increased. The lens portion 31 disposed at the outermost side of the vehicle of the projection lens 30 is configured to have the least spread of the emitted light to the outer side. According to this configuration, the space in front of the projection lens 30 and on the outer side of the vehicle can be effectively used to dispose other structures, and the degree of freedom of the layout is increased.

[0031] The above-described first reflecting portion 21 has a reflecting surface 21a that is recessed downward from both sides to the central portion in the left-right direction. The first reflecting portion 21 is provided in correspondence with the lens portion 31. Specifically, the first reflecting portion 21 is disposed to reflect light toward the corresponding lens portion 31 through the reflecting surface 21a.

[0032] The first reflecting portion 21 is disposed at a position where the optical axis AX with respect to the corresponding lens portion 31 becomes the inner side of the vehicle. Therefore, it is possible to form an ADB pattern in such a manner as to irradiate toward the outer side of the vehicle in front of the vehicle. Note that the first reflecting portion 21 can also be disposed so as to straddle the optical axis of the corresponding lens portion 31 in the left-right direction. In the present embodiment, the first reflecting portion 21 is provided with a plurality of, for example, two, for one lens portion 31. The two first reflecting portions 21 are disposed in a state of being connected to each other in the left-right direction.

[0033] The aforementioned second reflective portion 22 has a reflective surface 22a that is recessed downwards from both sides to the center in the left-right direction. One second reflective portion 22 is provided for each lens portion 31. That is, in this embodiment, a plurality of (two) first reflective portions 21 and one second reflective portion 22 are arranged in a left-right direction, corresponding to one lens portion 31. Furthermore, the second reflective portion 22 is disposed on the outer side of the vehicle in the left-right direction relative to the first reflective portion 21. And, three such structures, corresponding to the first reflective portion 21 and the second reflective portion 22, are arranged in the left-right direction. Hereinafter, when describing the relationship between the first reflective portion 21 and the second reflective portion 22 corresponding to one lens portion 31, it is sometimes referred to as the second reflective portion 22 corresponding to the first reflective portion 21, or the first reflective portion 21 corresponding to the second reflective portion 22. The second reflective portion 22 reflects light through the reflective surface 22a in a manner that prevents it from incident on the lens portion 31.

[0034] The second reflective portion 22 is disposed in the left-right direction between the first reflective portion 21 corresponding to it and the lens portion 31 adjacent to it on the outer side of the vehicle in the left-right direction. In this case, the second reflective portion 22 can be configured, for example, to be disposed between the optical axes AX of the adjacent lens portions 31 in the left-right direction. When forming a unilateral light distribution pattern, space is needed between the adjacent lens portions 31 in the left-right direction for forming a light-dark boundary forming portion, etc. In the structure of this embodiment, by distributing the second reflective portion 22 at the position of the light-dark boundary forming portion, it is possible to suppress the reflection of light from the position of the light-dark boundary forming portion toward the lens portion 31, and to suppress the generation of glare. In this embodiment, the second reflective portion 22 is disposed at a position on the outer side of the vehicle relative to the optical axis AX of each lens portion 31. With this structure, the second reflective portion 22 can be formed efficiently.

[0035] The boundary between the second reflective portion 22 and the first reflective portion 21 is formed as a light-dark boundary forming portion 22R along the optical axis AX (in Figure 4 (Represented by a dotted area). In the light-dark boundary forming section 22R, the second reflective section 22 has a rear end portion 22b that extends rearward from the first reflective section 21 in the front-rear direction. This structure makes it difficult for reflected light from the reflective surface 22a of the second reflective section 22 to enter the lens section 31. The rear end portion 22b can be straight or curved. The second reflective section 22 has a knurled portion 22c on its outer side. The knurled portion 22c scatters light.

[0036] The reflector 20 has a base plate 23, a partition wall 24, a light-shielding wall 25, and an outer frame 26. The base plate 23 is arranged, for example, along a horizontal plane and extends forward from the first reflector 21 and the second reflector 22. Figure 6 and Figure 7is a view showing an example of the reflector 20. Figure 6 is a perspective view as seen from the left rear and upper side, Figure 7 is a view showing a structure along Figure 1 of the B-B section in FIG. 10.

[0037] The partition wall 24 is provided in a manner of protruding upward from the bottom plate 23. The partition wall 24 is arranged along the front-rear direction between the lens portions 31 adjacent to each other in the left-right direction. The partition wall 24 is formed so that the height in the front-rear direction becomes higher toward the front. The partition wall 24 has an inclined portion 24s and a horizontal portion 24h. The inclined portion 24s is a portion in which the height gradually becomes higher toward the front from the rear end. The horizontal portion 24h is a portion in which the front end of the inclined portion 24s extends along a horizontal plane toward the front. According to this structure, it is possible to reliably shield the light traveling obliquely toward the front from the light source 10 toward the partition wall 24 on the front side of the partition wall 24. In addition, it is possible to reduce the material on the rear side of the partition wall 24, and thus it is possible to suppress the cost. In addition, the partition wall 24 is formed so that the side surface 24a is inclined toward the inside of the vehicle from the upper portion to the lower portion. According to this structure, when the reflector 20 is molded using a mold, it is possible to provide a space SP for pulling out the mold inside the partition wall 24.

[0038] The light-shielding wall 25 is arranged between the lens portions 31 adjacent to each other in the left-right direction. The light-shielding wall 25 shields the light traveling toward the outside of the vehicle from the light reflected by the first reflecting portion 21 toward the lens portion 31 adjacent to the lens portion 31 corresponding to the first reflecting portion 21. In the present embodiment, the light-shielding wall 25 is provided at the end portion of the partition wall 24 arranged on the outside of the vehicle, in front of the partition wall 24, with respect to each lens portion 31. In this case, the light-shielding wall 25 protrudes toward the inside of the vehicle. It is formed so that the amount of protrusion becomes larger from the upper portion to the lower portion. With this structure, it is possible to make the light-shielding amount of the light-shielding wall 25 be the minimum necessary amount.

[0039] The outer frame portion 26 is arranged at both ends in the left-right direction in the reflector 20. The outer frame portion 26 is formed so as to be curved upward from the bottom plate 23.

[0040] Next, the operation of the vehicle lamp 100 configured as described above will be described. Figure 8 is a view showing an example of the operation of the vehicle lamp 100. By lighting the light source 10 in the vehicle lamp 100, light is emitted from the light emitting surface 11. A part of the light emitted from the light emitting surface 11 reaches the reflecting surface 21a of the first reflecting portion 21. A part of the light reaching the reflecting surface 21a, the light L1, is reflected toward the front toward the corresponding lens portion 31, and is irradiated toward the front of the vehicle via the lens portion 31 to form an ADB pattern.

[0041] A portion of the light L2 reaching the reflecting surface 21a travels outward relative to the corresponding lens section 31. This light L2 is blocked by the light-shielding wall 25 at the front end of the partition wall 24. Therefore, the light L2 is suppressed from incident on the adjacent lens section 31 of the corresponding lens section 31.

[0042] Furthermore, a portion of the light L3 emitted from the light-emitting surface 11 reaches the reflecting surface 22a of the second reflecting section 22. The light L3 reaching the reflecting surface 22a is reflected in a direction different from that in front, for example, it is reflected or absorbed by the partition wall 24, or diffused by the knurled portion 22c. Therefore, the incident light L3 reaching the second reflecting section 22 onto the lens section 31 is suppressed. In this way, the light L3 can be suppressed from emitting in front of the vehicle, thus suppressing the generation of glare.

[0043] Figure 9 This is a diagram showing an example of the illumination pattern P of a vehicle lamp 100. Figure 9 In this context, HH lines represent horizontal lines, and VV lines represent lines parallel to the vertical direction (hereinafter referred to as vertical lines). For example... Figure 9 As shown, light L1 emitted from the exit surface 31b of the projection lens 30 forms an illumination pattern P in front of the vehicle. The illumination pattern P is arranged in a state where patterns P1 to P6 corresponding to each light source 10 are partially repeated in the left-right direction. Furthermore, in Figure 8 In this embodiment, the symbols for the light sources 10 corresponding to patterns P1, P2, P3, P4, P5, and P6 are respectively represented as S1, S2, S3, S4, S5, and S6. The vehicle lamp 100 of this embodiment is a so-called one-sided light distribution. Therefore, the illumination pattern P corresponds to the right part of the ADB pattern. The ADB pattern is formed by combining the illumination pattern of the vehicle lamp located on the left front of the vehicle. In each pattern P1, P2, P3, P4, P5, and P6, by providing a light-dark boundary forming part 22R, the left end of the pattern is formed into a straight, upright shape. That is, a clear light-dark boundary is formed. The patterns P4, P5, and P6 of the first reflector 21 adjacent to the second reflector 22 illuminate the vicinity of the VV line. Since the closer to the VV line, the stronger the light is, it can be said that the second reflector 22 is of great significance in suppressing glare.

[0044] As described above, the vehicle lamp 100 of this embodiment includes: a plurality of light sources 10 arranged in the left-right direction when mounted on a vehicle; a reflector 20 arranged in the left-right direction with a first reflector 21 that reflects light from the light sources 10 toward the front of the vehicle and a second reflector 22 that reflects light from the light sources 10 in a direction different from the front of the vehicle; and a projection lens 30 having a plurality of lens portions 31 arranged in the left-right direction that emit light reflected by the first reflector 21 toward the front of the vehicle to form an ADB pattern.

[0045] According to this structure, the second reflecting portion 22 is provided in a manner that is aligned with the first reflecting portion 21 in the left-right direction, and thus in a case where light from the light source 10 deviates in the left-right direction from the first reflecting portion 21 and reaches the second reflecting portion 22, the light can be reflected in a direction other than the front of the vehicle. Thus, light that deviates in the left-right direction from the first reflecting portion 21 can be prevented from being incident on the lens portion 31 in an unintended manner, and thus generation of glare can be suppressed.

[0046] In the vehicle lamp 100 according to the present embodiment, on the reflector 20, the first reflecting portion 21 and the second reflecting portion 22 are provided corresponding to each lens portion 31, the first reflecting portion 21 is disposed at a position where the optical axis with respect to the corresponding lens portion 31 becomes the inside of the vehicle, and the second reflecting portion 22 is disposed at a position where the optical axis with respect to each lens portion 31 becomes the outside of the vehicle.

[0047] According to this structure, the first reflecting portion 21 is disposed at a position where the optical axis with respect to the corresponding lens portion 31 becomes the inside of the vehicle, and thus light from the first reflecting portion 21 can be efficiently irradiated toward the front of the vehicle outside via the lens portion 31. In addition, the second reflecting portion 22 is disposed at a position where the optical axis with respect to each lens portion 31 becomes the outside of the vehicle, and thus by providing the shape of the reflecting surface 22a as a concave shape and providing the rear end portion 22b of the second reflecting portion 22 as a shape that faces the rear from the first reflecting portion 21, generation of glare toward the front of the vehicle inside from the lens portion 31 can be suppressed.

[0048] In the vehicle lamp 100 according to the present embodiment, the second reflecting portion 22 is disposed in the left-right direction between the first reflecting portion 21 corresponding to the second reflecting portion 22 and the lens portion 31 adjacent in the left-right direction with respect to the lens portion 31 corresponding to the second reflecting portion 22.

[0049] In the structure in which the ADB pattern is formed, sometimes a space or the like for forming the bright-dark boundary forming portion needs to be disposed between the optical axes AX of the lens portions 31 adjacent in the left-right direction. In the structure according to the present embodiment, the second reflecting portion 22 is disposed in the left-right direction between the first reflecting portion 21 corresponding to the second reflecting portion 22 and the lens portion 31 adjacent on the outside of the vehicle in the left-right direction with respect to the lens portion 31 corresponding to the second reflecting portion 22, and thus by disposing the second reflecting portion 22 at the position of the bright-dark boundary forming portion, reflection of light from the position of the bright-dark boundary forming portion toward the lens portion 31 can be suppressed, and generation of glare can be suppressed.

[0050] In the vehicle lamp 100 according to the present embodiment, the boundary of the second reflecting portion 22 and the first reflecting portion 21 is formed as the bright-dark boundary forming portion 22R along the optical axis AX.

[0051] According to this structure, the boundary with the first reflection portion 21 is formed as the bright-dark boundary formation portion 22R along the optical axis AX, so it is possible to suppress reflection of light toward the lens portion 31 from the position of the bright-dark boundary formation portion, and it is possible to suppress generation of glare.

[0052] In the vehicle lamp 100 of this embodiment, the second reflection portion 22 has a knurl portion 22c.

[0053] According to this structure, it is possible to diffuse light reaching the knurl portion 22c of the second reflection portion 22 using the knurl portion 22c, so it is possible to suppress generation of glare.

[0054] In the vehicle lamp 100 of this embodiment, the lens portion 31 disposed at the innermost side of the vehicle of the projection lens 30 forms the patterns P1, P4 in which the diffusion on the inner side of the emitted light is the least.

[0055] According to this structure, when other structures or the like are disposed in the space in front of the projection lens 30 and on the inner side of the vehicle, it is possible to effectively use this space, and the degree of freedom of the layout is increased.

[0056] In the vehicle lamp 100 of this embodiment, the lens portion 31 disposed at the outermost side of the vehicle of the projection lens 30 forms the patterns P3, P6 in which the diffusion on the outer side of the emitted light is the least.

[0057] According to this structure, when other structures or the like are disposed in the space in front of the projection lens 30 and on the outer side of the vehicle, it is possible to effectively use this space, and the degree of freedom of the layout is increased.

[0058] In the vehicle lamp 100 of this embodiment, the projection lens 30 is inclined toward the rear from the inner side to the outer side of the vehicle.

[0059] According to this structure, by setting the shape of the projection lens 30 to be inclined toward the rear from the inner side to the outer side of the vehicle, it is easy to follow the shape of the surroundings, and the layout property is improved.

[0060] In the vehicle lamp 100 of this embodiment, the first reflection portion 21 corresponding to one lens portion 31 is provided in plurality in the left-right direction.

[0061] According to this structure, the first reflection portion 21 corresponding to one lens portion 31 is provided in plurality in the left-right direction, so it is possible to set the irradiation pattern P (ADB pattern) more finely.

[0062] In the vehicle lamp 100 of this embodiment, the light source 10 is disposed corresponding to the first reflection portion 21, and a corresponding light source 10 is not disposed in the second reflection portion 22.

[0063] According to this structure, by providing the second reflection portion 22 in which the corresponding light source 10 is not provided, the clear and dark boundary can be formed more reliably, and the quality of the irradiation pattern P can be improved.

[0064] In the vehicle lamp 100 of this embodiment, the lens portions 31 adjacent to each other in the left-right direction of the reflector 20 have the light shielding wall 25 toward the inside of the vehicle therebetween.

[0065] According to this structure, the light reflected by the first reflection portion 21 and advancing toward the adjacent lens portion 31 of the corresponding lens portion 31 can be shielded. Thus, the generation of the glare can be suppressed by suppressing the undesirable light from being incident on the lens portion 31.

[0066] In the vehicle lamp 100 of this embodiment, the lens portions 31 adjacent to each other in the left-right direction of the reflector 20 have the partition wall 24 along the front-rear direction therebetween, and the light shielding wall 25 is provided at the end portion of the partition wall 24 in front.

[0067] According to this structure, the light shielding wall 25 is provided at the end portion of the partition wall 24 in front, and thus the light reflected by the first reflection portion 21 and advancing toward the adjacent lens portion 31 of the corresponding lens portion 31 can be more reliably shielded by the light shielding wall 25.

[0068] In the vehicle lamp 100 of this embodiment, the partition wall 24 is formed in a manner that the height in the up-down direction thereof is higher toward the front.

[0069] According to this structure, the light advancing toward the obliquely front side of the partition wall 24 among the light emitted from the light source 10 can be reliably shielded on the front side of the partition wall 24. In addition, the material can be reduced on the rear side of the partition wall 24, and thus the cost can be suppressed.

[0070] In the vehicle lamp 100 of this embodiment, the partition wall 24 is formed to be inclined toward the inside of the vehicle from the upper portion to the lower portion.

[0071] According to this structure, when the reflector 20 is molded using a mold, the thickness of the resin can be prevented from being thickened.

[0072] In the vehicle lamp 100 of this embodiment, the light shielding wall 25 is formed to have a smaller amount of protrusion toward the inside of the vehicle from the lower portion to the upper portion.

[0073] According to this structure, by reducing the amount of protrusion toward the inside of the vehicle from the lower portion to the upper portion of the light shielding wall 25, the amount of shielding of the light shielding wall 25 can be made to be the minimum necessary.

[0074] The technical scope of the present application is not limited to the above-described embodiments, and can be appropriately changed without departing from the gist of the present application.
