[0009] Hereinafter, with reference to the accompanying drawings, embodiments for carrying out the present invention (hereinafter referred to as "embodiments") will be described in detail. Throughout the description of the embodiments, the same elements are denoted by the same numbers or signs.

[0010] However, considering the clarity of the drawings, not all of the same elements are denoted by numbers or signs, and it should be noted that there are also elements for which numbers or signs are not given. In addition, for the sake of easy understanding of the explanation, there are also parts where the configuration is drawn emphasizing, and dimensions etc. are different from the actual ones.

[0011] <<First Embodiment>> The vehicle lamp 100 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 5.

[0012] FIG. 1 is a perspective view showing the vehicle lamp 100 according to the first embodiment of the present invention. Note that the longitudinal direction (length direction) of the vehicle lamp 100 may be described as the Z direction. FIG. 2 is an exploded perspective view of the vehicle lamp 100 according to the first embodiment of the present invention.

[0013] FIG. 3 is a cross-sectional view taken along line A - A of FIG. 1, showing only the light source unit 2, the inner lens 3, and the outer lens 4. In FIG. 3, for the sake of clarity, there are also parts where the illustration of the light source unit 2, the inner lens 3, and the outer lens 4 is omitted.

[0014] Also, in FIG. 3, the light irradiation direction of the vehicle lamp 100 is taken as the X direction, the front side (front side) in the light irradiation direction is taken as X1, and the rear side (rear side) in the light irradiation direction is taken as X2, and the same applies hereinafter. Note that in the vehicle lamp 100 of the first embodiment, the light irradiation direction (X direction) and the longitudinal direction (Z direction) of the vehicle lamp 100 shown in FIG. 1 are substantially the same, but it is not necessarily required to be the same.

[0015] Furthermore, in Figure 3, when the vehicle lighting fixture 100 is attached to the vehicle, the vertical direction (also called the vertical direction) is defined as Y, the upper side in the vertical direction (Y direction) is defined as Y1, and the lower side is defined as Y2, and the same applies hereafter.

[0016] Figure 4 is a perspective view showing a light source unit 2 of a first embodiment according to the present invention.

[0017] The vehicle light fixture 100 of the first embodiment is a light fixture installed on the front of a vehicle and comprises, for example, an upper light emitting section 2U that functions as a clearance lamp, daytime running lamp, etc., and a lower light emitting section 2L that functions as a turn signal lamp, etc., and is designed to reduce the visibility of the portion corresponding to the lower light emitting section 2L when it is not illuminated.

[0018] As shown in Figure 2, the vehicle light fixture 100 comprises a main body 1, a light source unit 2 attached to the main body 1, an inner lens 3 attached to the main body 1 so as to cover the light source unit 2, and an outer lens 4 attached to the main body 1 so as to cover the inner lens 3.

[0019] As shown in Figure 3, the vehicle light fixture 100 comprises a light source unit 2 consisting of an upper light emitting section 2U that emits light, a lower light emitting section 2L provided below the upper light emitting section 2U Y2 that emits light, and a partition section PT that separates the upper light emitting section 2U and the lower light emitting section 2L.

[0020] Furthermore, as shown in Figure 2, the vehicle light fixture 100 includes an inner lens 3 with a light-transmitting lens portion 30, and as shown in Figure 3, the lens portion 30 is provided in front of the upper light-emitting portion 2U and the lower light-emitting portion 2L in the direction of light emission X1.

[0021] [Upper light irradiation section 2U] As shown in Figure 3, the upper light irradiation section 2U includes an upper light source 21L provided at a distance Y1 above the partition section PT, and an upper reflector 21LR provided between the upper light source 21L and the partition section PT, which reflects light from the upper light source 21L in the light irradiation direction X.

[0022] In the first embodiment, the upper reflector 21LR is shown to be integrally molded with the partition PT, but the upper reflector 21LR and the partition PT may be separate components.

[0023] However, integrally molding the upper reflector 21LR and the partition PT is preferable because it reduces manufacturing costs and eliminates the need for an assembly process, thereby suppressing positional misalignment during assembly.

[0024] (Upper light source 21L) The upper light source 21L comprises an upper substrate 21B and an upper light-emitting chip 21LC provided on the lower surface 21B1 of the upper substrate, which is the lower surface Y2 of the upper substrate 21B. The upper light source 21L may also include a sealing resin to seal the upper light-emitting chip 21LC, and if the upper light-emitting chip 21LC is a blue LED, the sealing resin may contain a phosphor that emits yellow fluorescence.

[0025] Furthermore, in the first embodiment, as shown in Figure 3, the upper light irradiation unit 2U is provided between the upper substrate 21B and the upper reflector 21LR, and is equipped with a cover CV having an opening that allows light from the upper light source 21L to pass through at a position corresponding to the upper light-emitting chip 21LC.

[0026] Furthermore, the inner lens 3 has an opaque portion above the first upper light transmission 31UE of the first lens 31, which will be explained later, by two-color molding or painting. As a result, the upper light source 21L is positioned between this opaque portion and the cover CV, so the upper light source 21L is not visible from the outside, resulting in a good appearance.

[0027] On the other hand, in the first embodiment, the vehicle light fixture 100 is a slim, elongated shape as shown in Figure 1, and therefore the upper light source 21L is provided with multiple upper light-emitting chips 21LC that are spaced apart in the longitudinal direction Z of the vehicle light fixture 100 and are located on the lower surface 21B1 of the upper substrate, and as shown in Figure 4, multiple upper reflectors 21LR are provided in the longitudinal direction Z of the vehicle light fixture 100, corresponding to each upper light-emitting chip 21LC (not shown).

[0028] [Lower light irradiation section 2L] As shown in Figure 3, the lower light irradiation section 2L includes a lower light source 20L provided at a distance Y2 from the partition section PT, and a lower reflector 20LR provided between the lower light source 20L and the partition section PT, which reflects light from the lower light source 20L in the light irradiation direction X.

[0029] In the first embodiment, the lower reflector 20LR is shown to be integrally molded with the partition PT, but the lower reflector 20LR and the partition PT may be separate components.

[0030] However, integrally molding the lower reflector 20LR and the partition PT is preferable because it reduces manufacturing costs and eliminates the need for an assembly process, thereby suppressing positional misalignment during assembly.

[0031] (Lower light source 20L) The lower light source 20L comprises a lower substrate 20B and a lower light-emitting chip 20LC provided on the upper surface 20B1 of the lower substrate, which is the upper surface Y1 of the lower substrate 20B. The upper surface 20B1 of the lower substrate is black.

[0032] For example, the lower reflector 20LR is designed to reflect light, so its reflective surface is made of a color that easily reflects light, such as silver or white, making it easily visible from the outside even when not illuminated.

[0033] Therefore, in the first embodiment, the upper surface 20B1 of the lower substrate is made black so that the black color is reflected on the reflective surface of the lower reflector 20LR, making it difficult to see when not lit.

[0034] Furthermore, the lower reflector 20LR is positioned so that its entire surface is spaced apart from the front edge PTF on the forward X1 side in the light irradiation direction of the partition PT, and is spaced apart from the rear X2 side in the light irradiation direction. Thus, the lower reflector 20LR, which is easily visible from the outside even when not illuminated, is positioned so as to be hidden beneath the partition PT, making it difficult to see when not illuminated.

[0035] Furthermore, the lower substrate 20B is positioned X2 behind the leading edge PTF of the partition PT in the light irradiation direction. Therefore, the lower circuit board 20B is positioned so as to be hidden beneath the partition PT, making it difficult to see from the outside and resulting in a visually appealing design.

[0036] On the other hand, as explained earlier, in the first embodiment, the lamp is designed to be slim and elongated. Therefore, as shown in Figure 4, the lower light source 20L is provided with multiple lower light-emitting chips 20LC on the upper surface 20B1 of the lower substrate, spaced apart in the longitudinal direction Z of the vehicle lamp 100, and multiple lower reflectors 20LR are provided in the longitudinal direction Z of the vehicle lamp 100, corresponding to each of the lower light-emitting chips 20LC.

[0037] [Lens section 30] As shown in Figure 3, the lens section 30 includes a first lens 31 that corresponds to the upper light-emitting section 2U and transmits light from the upper light-emitting section 2U, and a second lens 32 that corresponds to the lower light-emitting section 2L and transmits light from the lower light-emitting section 2L.

[0038] (First lens 31) The first lens 31 includes a first upper light-transmitting portion 31U extending from the upper side Y1 to the lower side Y2, and a first lower light-transmitting portion 31L extending from the lower end 31UL of the first upper light-transmitting portion 31U toward the lower side Y2, and inclined toward the rear X2 in the direction of light irradiation.

[0039] More specifically, the first upper light-transmitting portion 31U of the first embodiment is formed to be inclined forward X1 in the light irradiation direction from the upper Y1 to the lower Y2, as shown in Figure 3.

[0040] Furthermore, the first lens 31 is equipped with a first upper light transmission 31UE that slopes in the direction of light irradiation, rearward X2, from the upper end 31UU of the first upper light transmission portion 31U toward the upper Y1, and as can be seen in Figure 2, the first lens 31 has a shape that protrudes outward overall.

[0041] Furthermore, the partition PT is positioned in the vertical direction (Y direction) near the lower end 31LL of the first lower light-transmitting section 31L, so that the lower light-emitting section 2L is not visible from the first lens 31 side.

[0042] (Second lens 32) As shown in Figure 3, the second lens 32 includes a second light-transmitting portion 321 that is inclined in the direction of light irradiation, backward X2, from the lower end 31LL of the first lower light-transmitting portion 31L toward the lower Y2, and a second lower light-transmitting portion 322 that is inclined backward X2 in the direction of light irradiation from the lower end of the second light-transmitting portion 321.

[0043] Then, the second light-transmitting section 321 is directed downward Y2 at a steep angle from the first lower light-transmitting section 31L, so that the light from the lower light-irradiating section 2L is appropriately irradiated from the second light-transmitting section 321 forward X1 in the light irradiation direction.

[0044] As explained earlier, this second lens 32 is a lens that corresponds to the lower light-emitting section 2L, which functions as a turn signal lamp or the like, and is not intended to be conspicuous when not illuminated.

[0045] Furthermore, the vehicle lighting fixture 100, which has lighting functions such as clearance lamps and daytime running lamps, is positioned at a height lower than a person's waist on the front of the vehicle, so when a person looks at the vehicle lighting fixture 100, they will be looking down at it.

[0046] When the vehicle light fixture 100 is viewed from above in this manner, a person's line of sight is directed towards the outward-protruding shape of the upper first lens 31, and when the lower light-emitting section 2L is not emitting light and is not illuminated, the second lens 32 located below the first lens 31 is difficult to recognize.

[0047] Furthermore, in the vehicle light fixture 100, the second light-transmitting portion 321 of the second lens 32 is inclined to the rear X2 in the light irradiation direction, so that it is recessed from the lower end 31LL of the first lower light-transmitting portion 31L which is the lower end of the first lens 31. This further reduces the visibility of the second lens 32 when it is not illuminated.

[0048] Figure 5 is a perspective view showing the inner lens 3 of the first embodiment according to the present invention. As shown in Figure 5, the second light-transmitting portion 321 has a vertical width smaller than the vertical (Y-direction) width of the first lens 31, making it less visible when not illuminated.

[0049] Furthermore, as can be seen from the fact that the second light-transmitting portion 321 extends without change in the longitudinal direction (Z direction) of the vehicle lamp 100, the second light-transmitting portion 321 extends in the longitudinal direction Z of the vehicle lamp 100 so as to correspond to all of the lower reflectors 20LR that are provided in the longitudinal direction Z of the vehicle lamp 100 as described above.

[0050] Therefore, when the lower light-emitting section 2L is lit, a long, slender, and aesthetically pleasing line of light is formed.

[0051] On the other hand, as shown in Figure 3, the inner lens 3 having the lens portion 30 includes a first design portion 33 provided on the lower side of the second lens 32.

[0052] Specifically, the first design portion 33 is an opaque portion that is black and does not transmit light, and in the first embodiment, the first design portion 33 is formed by applying black paint.

[0053] Furthermore, if we consider the case where the first design portion 33 is provided up to the immediate vicinity of the second light-transmitting portion 321, a mask would be placed on the second light-transmitting portion 321 and painted. However, if there is a gap between the mask and the second light-transmitting portion 321, there is a risk that paint may adhere to the second light-transmitting portion 321.

[0054] Therefore, the second lower light-transmitting section 322, as explained earlier, is provided, and the masking extends to the second lower light-transmitting section 322.

[0055] In this way, even if a small amount of paint adheres to the lower surface Y2 of the second lower light-transmitting section 322, there is no risk of it being visible, thus improving the paint yield. However, the first design portion 33 is not limited to being formed by painting, and may be formed by two-color molding or the like.

[0056] Furthermore, as shown in Figure 3, the outer lens 4 is provided with a light-transmitting portion 40 that is spaced forward X1 in the light irradiation direction from the lens portion 30.

[0057] As shown in Figure 2, the outer lens 4 is also provided with an extended light-transmitting portion 42 that extends from the upper end of the light-transmitting portion 40 and from the side end in the longitudinal direction Z (see Figure 1) to the rear X2 (see Figure 3) in the light irradiation direction.

[0058] As shown in Figure 3, the outer lens 4, like the inner lens 3, also includes a second design portion 41 provided on the lower side Y2 of the light-transmitting portion 40. Furthermore, this second design portion 41 is also an opaque black area that does not transmit light.

[0059] As can be seen in Figure 3, the upper Y1 end of the first design portion 33 is located higher Y1 than the lower substrate 20B, and the upper Y1 end 41A of the second design portion 41 is located further α higher Y1 than the upper Y1 end of the first design portion 33.

[0060] In other words, the upper end 41A of the second design portion 41 is located above the first design portion 33 and the lower substrate 20B.

[0061] In this way, by providing the second design portion 41 on the outer lens 4, when viewing the second lens 32 from the outer lens 4 side, the vertical width of the second lens 32 appears smaller to the extent that the second design portion 41 obstructs the field of view.

[0062] In other words, when the vehicle light fixture 100 is viewed from the front, the second lens 32 appears to be mounted in a narrower area, resulting in a better appearance.

[0063] Furthermore, because the second lens 32 picks up the black color of the second design portion 41, the second lens 32 appears black when not illuminated, further suppressing the perception of the second lens 32 as a lens.

[0064] As described above, the vehicle lighting fixture 100 of the first embodiment can suitably suppress the visibility of the part corresponding to the lower light-emitting section 2L, which is a part of the lighting fixture function that you do not want to stand out when it is not lit.

[0065] <<Second Embodiment>> Next, a vehicle lighting device 100 according to a second embodiment of the present invention will be described with reference to Figure 6.

[0066] The vehicle lighting fixture 100 of the second embodiment has the same basic configuration as the vehicle lighting fixture 100 of the first embodiment. Therefore, the following explanation will mainly focus on the differences from the first embodiment, and explanations of similar points may be omitted.

[0067] The difference between the vehicle lighting fixture 100 of the second embodiment and the vehicle lighting fixture 100 of the first embodiment lies in the configuration of the first lens 31 of the lens portion 30, and this point will be explained in detail below.

[0068] Figure 6 is a perspective view showing a part of the inner lens 3 of the second embodiment according to the present invention, and mainly shows only a part of the lens portion 30.

[0069] Since the first lens 31 will be located in a visible position, it may be better in terms of appearance to give it a novel design.

[0070] Therefore, in the second embodiment, as shown in Figure 6, the first lens 31 is provided as a set consisting of a first upper light-transmitting portion 31U, a first lower light-transmitting portion 31L, and a first upper light-transmitting portion 31UE, with multiple sets spaced apart in the longitudinal direction Z (see Figure 1) of the vehicle lamp 100, so that each of these sets corresponds to an upper reflector 21LR (not shown).

[0071] Although the present invention has been described above based on specific embodiments, the present invention is not limited to the above embodiments.

[0072] For example, in the above embodiment, the vehicle light fixture 100 was described as having a slim, elongated shape.

[0073] Therefore, the vehicle light fixture 100 had multiple upper light-emitting chips 21LC, upper reflectors 21LR, lower light-emitting chips 20LC, and lower reflectors 20LR provided in the longitudinal direction Z, but the number of these may be changed to match the shape required for the vehicle light fixture 100.

[0074] In other words, the upper light-emitting chip 21LC, the upper reflector 21LR, the lower light-emitting chip 20LC, and the lower reflector 20LR may each be present as just one of each.

[0075] Alternatively, the first upper light-transmitting portion 31UE of the first lens 31 may be omitted, and the first upper light-transmitting portion 31U may be tilted more towards the light irradiation direction (X direction) to achieve a more aesthetically pleasing design.
