Description

[Technical Field]

[0001] The present invention relates to a vehicle lamp. [Background technology]

[0002] A known vehicle lamp has a substrate on which a light emitter is mounted and a reflector attached to a heat sink, and a light-shielding wall protruding from the heat sink is disposed between the light emitter and a projection lens (see, for example, Patent Documents 1 and 2). In the vehicle lamps described in Patent Documents 1 and 2, the light-shielding wall blocks direct light traveling from the light emitter to the projection lens.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2024-18691 [Patent Document 2] Japanese Patent Application Publication No. 2018-190717 Summary of the Invention [Problem to be solved by the invention]

[0004] In the vehicle lamps described in Patent Documents 1 and 2, the light emitter, the light-shielding wall, and the reflector's reflecting surface are arranged close to one another in a narrow space partitioned by the reflecting surface of the reflector and the substrate, which makes it easy for the light emitter to rise in temperature. In particular, because the light-shielding wall rises at a right angle from the heat sink, the distance between the light emitter and the light-shielding wall is short, making it even more easy for the light emitter to rise in temperature.

[0005] In view of the above circumstances, the present invention aims to suppress the temperature rise of an illuminant in a vehicle lamp in which the illuminant, a shading portion, and the reflective surface of the reflector are arranged close to each other in a narrow space partitioned by the reflective surface of the reflector and a substrate. [Means for solving the problem]

[0006] The vehicle lamp of the present invention comprises a light emitter, a substrate on which the light emitter is mounted, an attachment portion to which the substrate is attached, a reflector that reflects light emitted from the light emitter toward the front of the lamp, and a shading portion that is arranged forward of the lamp than the light emitter and protrudes from the attachment portion side toward the reflector side, and blocks light emitted from the light emitter toward the front of the lamp, and the shading portion rises from the attachment portion side toward the reflector so as to be inclined toward the front of the lamp, and has an inclined surface that blocks light emitted from the light emitter toward the front of the lamp. [Effects of the Invention]

[0007] According to the present invention, in a vehicle lamp in which the light emitter, the light-shielding portion, and the reflector's reflective surface are arranged close to each other in a narrow space partitioned by the reflector's reflective surface and the substrate, the temperature rise of the light emitter can be suppressed.

DETAILED DESCRIPTION OF THE INVENTION

[0009] The present invention will be described below in accordance with preferred embodiments. Note that the present invention is not limited to the embodiments shown below and can be modified as appropriate without departing from the spirit of the present invention. In addition, in the embodiments shown below, some components are omitted from illustration and description, but for the details of the omitted technologies, publicly known or well-known technologies are applied as appropriate within the scope of the content described below.

[0010] FIG. 1 is a perspective view showing a vehicle lamp 1 according to one embodiment of the present invention. The vehicle lamp 1 shown in this figure is a low-beam headlamp that projects a low-beam light distribution pattern ahead of the vehicle. The vehicle lamp 1 is housed in a headlight housing (not shown) together with a high-beam headlamp (not shown). While a low-beam headlamp will be described as one embodiment of the present invention, other vehicle lamps, such as a high-beam headlamp or a side lamp, may also be used as one embodiment of the present invention. Furthermore, since a headlamp will be described as one embodiment of the present invention, the longitudinal direction of the vehicle and the longitudinal direction of the lamp coincide. However, if a side lamp is used as one embodiment of the present invention, the vehicle width direction and the longitudinal direction of the lamp will coincide. Furthermore, if a lamp that illuminates an intermediate position between the illumination position of the headlamp and the illumination position of the side lamp is used as one embodiment of the present invention, the illumination direction will coincide with the longitudinal direction of the lamp.

Furthermore, a reflective surface 351 of the fifth reflector unit 35 is provided so as to cover the fifth light emitter 415, and the reflective surface 351 reflects the light emitted from the fifth light emitter 415 toward the condensing lens unit 14.

[0033] The reflecting surface 311 of the first reflector portion 31, the reflecting surface 321 of the second reflector portion 32, the reflecting surface 331 of the third reflector portion 33, the reflecting surface 341 of the fourth reflector portion 34, and the reflecting surface 351 of the fifth reflector portion 35 are formed by aluminum deposition, high-reflection coating, etc. Furthermore, the reflecting surfaces 311, 321, 331, 341, and 351 are formed in a three-dimensional free-form surface shape based on an ellipse or a combination of an ellipse and a parabola.

[0034] The reflector 30 includes a first partition 310, a pillar 312, and a second partition 313. The first partition 310 is a wall-like member that separates the space in front of the second reflector section 32 and the third reflector section 33 into left and right sections, and blocks light traveling from the first irradiation unit U1 side to the second irradiation unit U2 side and light traveling from the second irradiation unit U2 side to the first irradiation unit U1 side. The pillar 312 is a pillar-like member that separates the space in back of the first diffusing lens section 11 and the third diffusing lens section 13, and blocks light traveling from the first irradiation unit U1 side to the third irradiation unit U3 side and light traveling from the third irradiation unit U3 side to the first irradiation unit U1 side.

[0035] The projection lens 10 is disposed on the vehicle front side of the reflector 30 and is attached to the heat sink 20 while being sandwiched between the reflector 30 and the heat sink 20. In the projection lens 10, the first diffusing lens unit 11 is disposed in front of the first reflector unit 31 and the second reflector unit 32 and projects light reflected by the reflective surface 311 of the first reflector unit 31 and the reflective surface 321 of the second reflector unit 32 toward the front of the vehicle. The second diffusing lens unit 12 is disposed in front of the third reflector unit 33 and projects light reflected by the reflective surface 331 of the third reflector unit 33 toward the front of the vehicle. The third diffusing lens unit 13 is disposed in front of the fourth reflector unit 34 to the right and projects light reflected by the reflective surface 341 of the fourth reflector unit 34 toward the front right of the vehicle. Furthermore, the condenser lens portion 14 is disposed in front of the fifth reflector portion 35, and projects the light reflected by the reflecting surface 351 of the fifth reflector portion 35 in front of the vehicle.

[0036] In the projection lens 10, the exit surfaces of the condenser lens portion 14, the second diffusing lens portion 12, and the first diffusing lens portion 11 are formed as continuous curved surfaces that extend in the vehicle width direction. In contrast, the exit surface of the third diffusing lens portion 13 extends diagonally rearward and to the right of the vehicle from the boundary with the exit surface of the first diffusing lens portion 11. As a result, the projection lens 10 as a whole has a slanted shape that extends rearward as it moves from the inside to the outside in the vehicle width direction.

[0037] The incident surface of the condensing lens unit 14 is a convex surface that bulges toward the fifth reflector unit 35, and the condensing lens unit 14 is a condensing lens (convex lens). The incident surface of the second diffusing lens unit 12 is a concave surface that recesses toward the exit surface, and the second diffusing lens unit 12 is a diffusing lens (concave lens). The incident surface of the first diffusing lens unit 11 is a concave surface that recesses toward the exit surface, and the first diffusing lens unit 11 is a diffusing lens (concave lens). The incident surface of the third diffusing lens unit 13 is a concave surface that recesses toward the exit surface, and the third diffusing lens unit 13 is a diffusing lens (concave lens).

[0038] A step portion 352 for forming a cutoff line is formed at the end portion on the vehicle rear side of the fifth reflector portion 35. Light emitted from the fifth light emitter 415 toward the vehicle rear side and reflected by the lower end of the reflecting surface 351 of the fifth reflector portion 35 is projected by the condensing lens portion 14 toward the front of the vehicle, whereby a light distribution pattern with a cutoff line formed is irradiated toward the front of the vehicle.

[0039] Here, the projection lens 10 is formed with an area (hereinafter referred to as the light distribution control area) having a light distribution control function for the first diffusing lens section 11, a light distribution control area for the second diffusing lens section 12, a light distribution control area for the third diffusing lens section 13, and a light distribution control area for the condensing lens section 14. One light emitter (third light emitter 413, fourth light emitter 414, or fifth light emitter 415) is provided corresponding to each of the light distribution control areas of the second diffusing lens section 12, the third diffusing lens section 13, and the condensing lens section 14. The third light emitter 413 is housed in a space partitioned by the third reflector section 33, the substrate 42, and the first base section 21A. The fourth light emitter 414 is housed in a space partitioned by the fourth reflector section 34, the substrate 42, and the first base section 21A. The fifth light emitter 415 is housed in a space defined by the fifth reflector portion 35, the substrate 42, and the first base portion 21A.

[0040] In contrast, two light emitters (first light emitter 411 and second light emitter 412) are provided corresponding to the light distribution control area of ​​first diffusion lens unit 11. First light emitter 411 and second light emitter 412 are arranged adjacent to each other in the vehicle width direction and are housed in a space partitioned by first reflector unit 31, second reflector unit 32, substrate 42, and first base unit 21A. Therefore, the space housing first light emitter 411 and second light emitter 412 is more susceptible to temperature rise due to thermal energy of the light emitters than the spaces housing third light emitter 413, fourth light emitter 414, or fifth light emitter 415, respectively.

[0041] 4 is a plan view showing the vehicle lamp 1 of FIG. 1 etc. As shown in this figure, a connector housing portion 38 that houses a connector 43 is provided at the end portion of the reflector 30 on the vehicle rear side. The first reflector portion 31 and the second reflector portion 32 are arranged near the connector housing portion 38.

[0042] Fig. 5 is a VV cross-sectional view of Fig. 4. This figure shows a cross section cut along a vertical plane passing through the second light emitter 412. As shown in this figure, a board 42 on which the second light emitter 412 and the like are mounted is attached to the upper surface of the first base portion 21A, and the reflective surface 321 of the second reflector portion 32 is disposed so as to face the board 42 in the vehicle vertical direction. An end portion of the reflective surface 321 of the second reflector portion 32 on the vehicle rear side (hereinafter referred to as the rear end portion) is disposed further rearward of the second light emitter 412.

[0043] The reflecting surface 321 of the second reflector portion 32 is formed in a three-dimensional free-form surface shape that is curved so that its height from the substrate 42 gradually increases from the rear end to the end toward the front of the vehicle (hereinafter referred to as the front end), and the angle between the tangent of the reflecting surface 321 and the horizontal plane gradually decreases.

[0044] The second light-shielding wall 212 is a plate piece formed integrally with the first base portion 21A by bending, and protrudes from the first base portion 21A to the upper side of the substrate 42 through the first insertion hole 421. Here, the second light-shielding wall 212 is formed by bending at an obtuse angle, and protrudes obliquely upward from the first base portion 21A so as to be inclined toward the front side of the vehicle. The inclined surface 212A rises from the upper surface of the first base portion 21A so as to be inclined toward the front side of the vehicle.

[0045] 6 is a cross-sectional view taken along line VI-VI in FIG. 4. This figure shows a cross section cut along a vertical plane passing through first light emitter 411. As shown in this figure, reflective surface 311 of first reflector portion 31 is disposed so as to face substrate 42 in the vehicle vertical direction. An end portion of reflective surface 311 of first reflector portion 31 on the vehicle rear side (hereinafter referred to as rear end portion) is disposed further rearward of first light emitter 411.

[0046] The first light-shielding wall 211 is a plate piece formed integrally with the first base portion 21A by bending, and protrudes from the first base portion 21A to the upper side of the substrate 42 through the first insertion hole 421. Here, the first light-shielding wall 211 is formed by bending at an obtuse angle, and protrudes obliquely upward from the first base portion 21A so as to be inclined toward the front side of the vehicle.

[0047] The first light-shielding wall 211 has an inclined surface 211A, an end surface 211B, and an R-shaped portion 211C. The inclined surface 211A is a surface that rises from the upper surface of the first base portion 21A and is inclined toward the front of the vehicle. The inclined surface 211A blocks light emitted from the first light emitter 411 toward the front of the vehicle. The end surface 211B is a surface formed at the tip of the first light-shielding wall 211. The R-shaped portion 211C is an R-shaped portion formed at the boundary between the inclined surface 211A and the end surface 211B. The inclined surface 211A, the end surface 211B, and the R-shaped portion 211C are subjected to treatments such as anodizing or painting to reduce reflectivity. Note that, depending on the material of the first light-shielding wall 211, it is possible not to perform the anodizing treatment, but it is more preferable to perform the anodizing treatment.

[0048] A pin 391 that protrudes toward the substrate 42 is formed on the base portion 39 of the reflector 30. The pin 391 abuts against the upper surface of the substrate 42.

[0049] Fig. 7 is an enlarged cross-sectional view of a portion of Fig. 6. As shown in this figure, the angle α between the inclined surface 211A of the first light-shielding wall 211 and the horizontal plane is an acute angle (for example, 75 to 85°, more preferably 78 to 82°, and 80° in this embodiment). Also, the angle α' between the inclined surface 211A of the first light-shielding wall 211 and the vertical plane is an acute angle (for example, 5 to 15°, more preferably 8 to 12°, and 10° in this embodiment).

[0050] An end surface 211B of the first light-shielding surface 211 is inclined downward toward the front of the vehicle. The angle β between the end surface 211B and the horizontal plane is an acute angle (for example, 5 to 15°, more preferably 8 to 12°, and 10° in this embodiment).

[0051] The angle θ between the tangent to the reflecting surface 311 of the first reflector part 31 and the vertical line gradually increases from the rear end to the front end of the reflecting surface 311. The angle θ is smallest at the rear end of the reflecting surface 311, and the minimum value of the angle θ is smaller than the angle α' between the inclined surface 211A of the first light-shielding wall 211 and the vertical line.

[0052] The second light-shielding wall 212 has the same configuration as the first light-shielding wall 211, and includes an inclined surface 212A similar to the inclined surface 211A, an end surface 212B similar to the end surface 211B, and an R-shaped portion 212C similar to the R-shaped portion 211C (see FIGS. 5, 9, and 10). The third light-shielding wall 213 and the fifth light-shielding wall 215 have the same configuration as the first light-shielding wall 211 and the second light-shielding wall 212, except for their different arrangements. The fourth light-shielding wall 214 has the same configuration as the first light-shielding wall 211 and the second light-shielding wall 212, except for their different arrangement and orientation.

[0053] 8 is a cross-sectional view taken along the line VIII-VIII of FIG. 4. This figure shows a cross section cut along a vertical plane passing through the first light-shielding wall 211. In the cross section shown in this figure, an opening is formed between the end of the reflector 30 on the vehicle rear side and the end of the heat sink 20 on the vehicle rear side, and a gap is formed from the opening to the first light-shielding wall 211 between the base portion 39 or the reflective surface 311 and the first base portion 21A or the substrate 42. As a result, convection occurs from the space defined by the reflective surface 311 and the substrate 42 to the rear of the vehicle lamp 1, as will be described in detail later.

[0054] Fig. 9 is a perspective view showing the inside of the vehicle lamp 1 of Fig. 1 etc. This figure shows the inside of the first illumination unit U1 with a part of the first reflector portion 31 and the entire bracket portion 22 cut away.

[0055] 9, the first light emitter 411 and the second light emitter 412 are arranged in a narrow space surrounded by the substrate 42 and the first and second reflector portions 31 and 32. The first light-shielding wall 211 protrudes through the first insertion hole 421 to the vicinity of the first light emitter 411 on the substrate 42, and the second light-shielding wall 212 protrudes through the first insertion hole 421 to the vicinity of the second light emitter 412 on the substrate 42. The first light-shielding wall 211 and the second light-shielding wall 212 are arranged side by side in the vehicle width direction with a gap between them. Note that one light-shielding wall may be provided for the first light emitter 411 and the second light emitter 412 arranged side by side in the vehicle width direction.

[0056] 10 is a perspective view showing the first light-shielding wall 211 and the second light-shielding wall 212, etc., of FIG. 2 etc. In this figure, the illustration of the substrate 42 is omitted except for the first insertion holes 421 indicated by dashed lines. As shown in FIG. 10, rectangular openings 216 are formed in the first base portion 21A by punching around the first light-shielding wall 211 and the second light-shielding wall 212. The openings 216 are punched holes formed in the first base portion 21A to form the first light-shielding wall 211 and the second light-shielding wall 212.

[0057] Here, the first insertion hole 421 formed in the substrate 42 is located on the inner circumferential side of the opening 216 formed in the first base portion 21 when viewed in the vehicle vertical direction. The opening 216 has an outer shape that is slightly larger than the outer shape of the first insertion hole 421 and goes around the outer circumferential side of the periphery of the first insertion hole 421.

[0058] Fig. 11 is a cross-sectional view for explaining convection currents that occur inside the vehicle lamp 1 of Fig. 1 etc. As shown in this figure, the first light-shielding wall 211 is inclined so as to gradually move away from the first light emitter 411 from the base end side to the tip end side, which makes it easier for convection currents to flow near the first light emitter 411. In addition, convection currents occur from the first light emitter 411 side through the left and right sides of the pin 391 to the rear of the vehicle lamp 1.

[0059] Furthermore, although not shown in the figure, the second light-shielding wall 212 is inclined so as to gradually move away from the second light-emitting body 412 from the base end side to the tip end side, which makes it easier for convection currents to flow near the second light-emitting body 412.

[0060] That is, in the narrow space of the first irradiation unit U1 in which the first light emitter 411 and the second light emitter 412 and the first light-shielding wall 211 and the second light-shielding wall 212 are arranged close to each other, convection tends to flow near the first light emitter 411 and the second light emitter 412, and convection occurs that reaches the rear of the vehicle lamp 1. Therefore, it is possible to suppress a temperature rise in the narrow space in which the first light emitter 411 and the second light emitter 412 and the first light-shielding wall 211 and the second light-shielding wall 212 are arranged close to each other, and it is possible to suppress a temperature rise in the first light emitter 411 and the second light emitter 412.

[0061] In addition, the same effect as in the space of the first irradiation unit U1 occurs in the space of the second irradiation unit U2 in which the third light-emitting body 413 and the third light-shielding wall 213 are arranged, the space of the third irradiation unit U3 in which the fourth light-emitting body 414 and the fourth light-shielding wall 214 are arranged, and the space of the fourth irradiation unit U4 in which the fifth light-emitting body 415 and the fifth light-shielding wall 215 are arranged.

[0062] 12 is a cross-sectional view illustrating convection currents that occur inside a vehicle lamp of a comparative example. In the vehicle lamp of the comparative example shown in this figure, the first light-shielding wall 211′ is formed by bending at a right angle and protrudes at a right angle from the first base portion 21A toward the upper side of the vehicle.

[0063] 12, the first light-shielding wall 211' protrudes at a right angle from the first base portion 21A, which makes it difficult for convection currents to flow near the first light emitter 411. That is, in a narrow space in which the first light emitter 411 and the second light emitter 412 and the first light-shielding wall 211' and the second light-shielding wall 212' are arranged close to each other, convection currents do not flow easily near the first light emitter 411 and the second light emitter 412. Therefore, a temperature rise is likely to occur in the narrow space in which the first light emitter 411 and the second light emitter 412 and the first light-shielding wall 211' and the second light-shielding wall 212' are arranged close to each other, and the temperature of the first light emitter 411 and the second light emitter 412 is likely to rise.

[0064] 2 etc. and the relationship between the first light-shielding wall 211 and the light reflected by the first reflector unit 31. As shown in this figure, the reflecting surface 311 of the first reflector unit 31 is curved so as to extend forward from a point rearward and upward of the vehicle relative to the first light emitter 411, bulging out upward from the vehicle, and reflects the light emitted by the first light emitter 411 diagonally downward toward the front of the vehicle.

[0065] The area of ​​the reflective surface 311 of the first reflector portion 31 that is located rearward of the first light emitter 411 reflects the light emitted from the first light emitter 411 toward the rear and upper sides of the vehicle diagonally downward and forward of the vehicle.

[0066] 12, the end surface 211B of the first light-shielding wall 211' faces vertically upward. Therefore, light reflected diagonally downward and forward from the rear region of the reflecting surface 311 of the first reflector portion 31 is reflected by the end surface 211B of the first light-shielding wall 211', becoming harmful light that causes glare, light streaks, and the like.

[0067] In contrast, in this embodiment, the end surface 211B of the first light-shielding wall 211 is inclined downward toward the front of the vehicle. Therefore, light reflected diagonally downward toward the front of the vehicle by the rear region of the reflective surface 311 of the first reflector portion 31 is prevented from being reflected by the end surface 211B, thereby suppressing harmful light that causes glare, light streaks, etc. In particular, in this embodiment, the angle β between the end surface 211B and the horizontal plane is set to be equal to or greater than the angle γ between the light ray reflected by the rear region of the reflective surface 311 of the first reflector portion 31 and the horizontal plane, thereby improving the effect of suppressing harmful light that causes glare, light streaks, etc.

[0068] Furthermore, although not shown, the end surface 212B of the second light-shielding wall 212 is inclined downward toward the vehicle front. This prevents light reflected diagonally downward toward the vehicle front by the rear region of the reflective surface 321 of the second reflector portion 32 from being reflected by the end surface 212B, thereby suppressing harmful light that causes glare, light streaks, etc. In particular, in this embodiment, the angle β between the end surface 212B and the horizontal plane is set to be equal to or greater than the angle γ between the light ray reflected diagonally downward toward the vehicle front by the rear region of the reflective surface 321 of the second reflector portion 32 and the horizontal plane, thereby improving the effect of suppressing harmful light that causes glare, light streaks, etc.

[0069] In addition, since the third light-shielding wall 213, the fourth light-shielding wall 214, and the fifth light-shielding wall 215 are configured in the same manner as the first light-shielding wall 211 and the second light-shielding wall 212, the second irradiation unit U2, the third irradiation unit U3, and the fourth irradiation unit U4 also have the same effect of suppressing harmful light that causes glare, light streaks, etc. as the first irradiation unit U1.

[0070] As described above, in the vehicle lamp 1 of this embodiment, the substrate 42 on which the first light emitter 411 and the second light emitter 412 are provided is attached to the first base portion 21A, and the reflective surfaces 311, 321 of the reflector 30 reflect light emitted from the first light emitter 411 or the second light emitter 412 toward the front of the lamp. The light emitted from the first light emitter 411 toward the front of the vehicle is blocked by the first light-shielding wall 211, and the light emitted from the second light emitter 412 toward the front of the vehicle is blocked by the second light-shielding wall 212. This suppresses direct light emitted from the first light emitter 411 and the second light emitter 412 and reaching the projection lens 30 directly.

[0071] Here, the reflective surfaces 311, 321 of the reflector 30 are provided so as to extend from a position further rearward than the first light emitter 411 and the second light emitter 412 to a position further forward than the first light-shielding wall 211 and the second light-shielding wall 212, and a narrow space is defined by the reflective surfaces 311, 321 and the substrate 42, in which the first light emitter 411, the second light emitter 412, the first light-shielding wall 211, and the second light-shielding wall 212 are arranged close to each other. For this reason, a temperature rise is likely to occur in the space due to the thermal energy of the first light emitter 411 and the second light emitter 412.

[0072] In contrast, in the vehicle lamp 1 of this embodiment, the light-shielding surface of the first light-shielding wall 211 that blocks light emitted from the first light emitter 411 toward the front of the lamp is an inclined surface 211A that rises from the first base portion 21A side toward the reflector 30 so as to be inclined toward the front of the lamp. Also, the light-shielding surface of the second light-shielding wall 212 that blocks light emitted from the second light emitter 412 toward the front of the lamp is an inclined surface 212A that rises from the first base portion 21A side toward the reflector 30 so as to be inclined toward the front of the lamp. This facilitates convection near the first light emitter 411 and the second light emitter 412, and suppresses a temperature rise near the first light emitter 411 and the second light emitter 412 due to the thermal energy of the first light emitter 411 and the second light emitter 412 and the thermal energy of the light reflected by the reflecting surfaces 311, 321.

[0073] Furthermore, in the vehicle lamp 1 of this embodiment, an area (rear area) of the reflecting surface 311 of the reflector 30 that is rearward of the first light emitter 411 reflects light emitted from the first light emitter 411 diagonally downward and forward of the lamp. Furthermore, an area (rear area) of the reflecting surface 321 of the reflector 30 that is rearward of the second light emitter 412 reflects light emitted from the second light emitter 412 diagonally downward and forward of the lamp. In contrast, a top surface (end surface 211B) provided on the vehicle front side of the inclined surface 211A of the first light-shielding wall 211 is inclined downward and forward of the lamp. Furthermore, a top surface (end surface 212B) provided on the vehicle front side of the inclined surface 212A of the second light-shielding wall 212 is inclined downward and forward of the lamp. This prevents light reflected obliquely downward and forward of the vehicle by the rear region of the reflecting surface 311 of the reflector 30 from being reflected by the end surface 211B of the first light-shielding wall 211, thereby suppressing harmful light that causes glare, light streaks, etc. Furthermore, light reflected obliquely downward and forward of the vehicle by the rear region of the reflecting surface 321 of the reflector 30 from being reflected by the end surface 212B of the second light-shielding wall 212, thereby suppressing harmful light that causes glare, light streaks, etc.

[0074] In particular, in the vehicle lamp 1 of this embodiment, the depression angle (angle β) of the end surface 211B of the first light-shielding wall 211 is equal to or greater than the depression angle (angle γ) of light reflected obliquely downward and forward of the vehicle by the rear region of the reflecting surface 311 of the reflector 30. This further prevents the light reflected obliquely downward and forward of the vehicle by the rear region of the reflecting surface 311 of the reflector 30 from being reflected by the end surface 211B of the first light-shielding wall 211 and becoming harmful light that causes glare, light streaks, etc. Furthermore, the depression angle (angle β) of the end surface 212B of the second light-shielding wall 212 is equal to or greater than the depression angle (angle γ) of light reflected obliquely downward and forward of the vehicle by the rear region of the reflecting surface 321 of the reflector 30. This further prevents light reflected diagonally downward in front of the vehicle in the rear region of the reflecting surface 321 of the reflector 30 from being reflected by the end surface 212B of the second shading wall 212 and becoming harmful light that causes glare, light streaks, etc.

[0075] Moreover, in the vehicle lamp 1 of this embodiment, the first base portion 21A to which the substrate 42 is attached, the first light-shielding wall 211, and the second light-shielding wall 212 are provided on the heat sink 20, which is a press-formed product formed integrally with the first base portion 21A, and the top surface of the first light-shielding wall 211 is an end surface 211B of a metal plate, and the top surface of the second light-shielding wall 212 is an end surface 212B of a metal plate. By bending the first light-shielding wall 211 so that the end surface 211B is inclined downward toward the front side of the lamp, light reflected at the rear region of the reflecting surface 311 of the reflector 30 is prevented from being reflected by the end surface 211B of the first light-shielding wall 211 and becoming harmful light that causes glare, light streaks, etc. In addition, the second light-shielding wall 212 is bent so that the end face 212B is inclined downward toward the front of the lamp, thereby preventing light reflected in the rear region of the reflective surface 321 of the reflector 30 from being reflected by the end face 212B of the second light-shielding wall 212 and becoming harmful light that causes glare, light streaks, etc.

[0076] Moreover, in the vehicular lamp of this embodiment, the first light-shielding wall 211 has an R-shaped portion 211C formed at the boundary between the inclined surface 211A and the end surface 211B. This facilitates convection near the end surface 211B of the first light-shielding wall 211, thereby suppressing a temperature rise in the first light emitter 411. Furthermore, light reflected obliquely downward and forward of the vehicle from the rear region of the reflecting surface 311 of the reflector 30 is prevented from being reflected by the end surface 211B of the first light-shielding wall 211 and becoming harmful light that causes glare, light streaks, etc. The R-shaped portion 211C includes an angular shape such as a C-face and any curved shape (such as an elliptical shape).

[0077] The second light-shielding wall 212 also has an R-shaped portion 212C formed at the boundary between the inclined surface 212A and the end surface 212B. This facilitates convection near the end surface 212B of the second light-shielding wall 212, thereby suppressing a temperature rise in the second light emitter 412. Furthermore, light reflected obliquely downward and forward of the vehicle from the rear region of the reflecting surface 321 of the reflector 30 is prevented from being reflected by the end surface 212B of the second light-shielding wall 212 and becoming harmful light that causes glare, light streaks, etc. The R-shaped portion 212C includes an angular shape such as a C-face and any curved shape (such as an elliptical shape).

[0078] Furthermore, in the vehicle lamp 1 of this embodiment, the reflective surface 311 of the reflector 30 is inclined so that the angle with respect to the vertical gradually increases from the rear side of the lamp relative to the first light emitter 411 to the front side of the lamp relative to the first light-shielding wall 211. Here, the minimum value of the angle (angle θ) of the reflective surface 311 of the reflector 30 with respect to the vertical is smaller than the angle α' of the inclined surface 211A of the first light-shielding wall 211 with respect to the vertical. In other words, the angle of the reflective surface 311 with respect to the vertical is minimum at the lower end of the reflective surface 311 of the reflector 30, so that the lower end is close to the first light emitter 411. On the other hand, the angle α' of the inclined surface 211A of the first light-shielding wall 211 with respect to the vertical is larger than the angle θ. Therefore, a larger space can be secured to surround the first light emitter 411 due to the space created by the angle α' being larger than the angle θ. This facilitates convection from the heat source, and the influence of thermal energy on the first light emitter 411 between the reflecting surface 311 of the reflector 30 and the inclined surface 211A of the first light-shielding wall 211 can be alleviated.

[0079] Furthermore, the reflecting surface 321 of the reflector 30 is inclined so that the inclination angle with respect to the vertical gradually increases from the rear side of the second light emitter 412 to the front side of the lamp of the second light-shielding wall 212. Here, the minimum value of the angle (angle θ) of the reflecting surface 321 of the reflector 30 with respect to the vertical is smaller than the angle α' of the inclined surface 212A of the second light-shielding wall 212 with respect to the vertical. That is, the angle of the reflecting surface 321 with respect to the vertical is minimum at the lower end of the reflecting surface 321 of the reflector 30, so that the lower end is close to the second light emitter 412. On the other hand, the angle α' of the inclined surface 212A of the second light-shielding wall 212 with respect to the vertical is larger than the angle θ. Therefore, the space surrounding the second light emitter 412 can be made larger due to the space created by the angle α' being larger than the angle θ. This facilitates convection from the heat source, and the influence of thermal energy on the second light emitter 412 between the reflecting surface 321 of the reflector 30 and the inclined surface 212A of the second light-shielding wall 212 can be alleviated.

[0080] Furthermore, in the vehicle lamp 1 of this embodiment, a convection flow path is formed that guides convection from between the reflector 30 and the substrate 42 to the outside behind the lamp. This suppresses a temperature rise near the first light emitter 411 and the second light emitter 412 due to the thermal energy of the first light emitter 411 and the second light emitter 412 and the thermal energy of the light reflected by the reflecting surfaces 311, 321.

[0081] Furthermore, in the vehicle lamp 1 of this embodiment, the first base portion 21A to which the substrate 42 is attached, the first light-shielding wall 211, and the second light-shielding wall 212 are provided on the heat sink 20, which is a press-formed product formed integrally with these. The first base portion 21A is formed with an opening 216, which is a punched hole for forming the first light-shielding wall 211 and the second light-shielding wall 212, and the substrate 42 is formed with a first insertion hole 421, through which the first light-shielding wall 211 and the second light-shielding wall 212 are inserted.

[0082] Here, the opening 216 has an outer shape that is slightly larger than the outer shape of the first insertion hole 421 and that circles around the outer periphery of the first insertion hole 421 more outer than the peripheral edge of the first insertion hole 421. As a result, convection occurs around the first light-shielding wall 211 and the second light-shielding wall 212 through the first insertion hole 421 and the opening 216, so that a rise in temperature of the first light-shielding wall 421 and the second light-shielding wall 212 can be suppressed.

[0083] The vehicle lamp 1 of this embodiment is also provided with a projection lens 10 that irradiates light reflected by the reflective surfaces 311, 321 of the reflector 30 forward of the lamp. The projection lens 10 is provided with a first diffusing lens section 11 that controls the light distribution of light emitted from the first light emitter 411 and the second light emitter 412 and reflected by the reflective surfaces 311, 321 of the reflector 30, and a second diffusing lens section 12, a third diffusing lens section 13, and a condensing lens section 14 that control the light distribution of light emitted from other light emitters and reflected by other reflective surfaces of the reflector 30.

[0084] That is, a plurality of light emitters (first light emitter 411 and second light emitter 412), a plurality of light shielding walls (first light shielding wall 211 and second light shielding wall 212), and a plurality of reflecting surfaces 311, 321 are provided corresponding to one of a plurality of light distribution control areas of the projection lens 10. Therefore, the first light emitter 411, the second light emitter 412, the first light shielding wall 211, the second light shielding wall 212, and the reflecting surfaces 311, 321 have to be arranged close to each other, which makes it easy for the temperature of the first light emitter 411 and the second light emitter 412 to rise.

[0085] In contrast, the inclined surface 211A of the first light-shielding wall 211 and the inclined surface 212A of the second light-shielding wall 212 rise from the first base portion 21A side to the reflecting surfaces 311, 321 side so as to be inclined toward the front of the lamp. As a result, by being provided corresponding to one light distribution control area of ​​the projection lens 10, it is possible to suppress a rise in temperature of the first light emitter 411 and the second light emitter 412 that are arranged closely to each other.

[0086] In particular, since the first light-shielding wall 211 and the second light-shielding wall 212 are disposed apart from each other, a convection flow path that guides convection to the first light-emitting body 411 and the second light-emitting body 412 is formed between the first light-shielding wall 211 and the second light-shielding wall 212. This makes it possible to more effectively suppress the temperature rise of the first light-emitting body 411 and the second light-emitting body 412 that are disposed close to each other.

[0087] Although the present invention has been described above based on the above-mentioned embodiments, the present invention is not limited to the above-mentioned embodiments, and modifications may be made without departing from the spirit of the present invention, and techniques from the embodiments or well-known or publicly known techniques may be combined.

[0088] For example, in the above embodiment, the heat sink 20 is formed by press working, but the heat sink 20 may be formed by die casting. Also, the first light-shielding wall 211, the second light-shielding wall 212, the third light-shielding wall 213, the fourth light-shielding wall 214, and the fifth light-shielding wall 215 are formed by bending working, but they may be formed by die casting.
