Embodiments for Carrying Out the Invention

[0010] Hereinafter, the present invention will be described with reference to the drawings based on preferred embodiments. The embodiments are illustrative rather than limiting the invention, and all features and combinations thereof described in the embodiments are not necessarily essential to the invention. The same or equivalent components, members, and processes shown in each drawing are denoted by the same reference numerals, and redundant descriptions are omitted as appropriate. Also, the scales and shapes of the respective parts shown in each figure are set for convenience in order to facilitate the explanation, and are not to be construed in a limited manner unless otherwise specified. Further, when terms such as "first" and "second" are used in this specification or claims, unless otherwise specified, these terms do not represent any order or importance, but are for distinguishing one configuration from another. Also, some members that are not important in explaining the embodiments are omitted from the drawings.

[0011] FIG. 1 is a perspective view of a vehicle lamp 1 according to the embodiment. FIG. 2 is an exploded perspective view of the vehicle lamp 1. The vehicle lamp 1 is a rear lamp disposed at the rear of a vehicle as an example. In the figure, "front" means the front of the lamp (the rear of the vehicle), "rear" means the rear of the lamp (the front of the vehicle), "inner" means the inner side in the vehicle width direction, "outer" means the outer side in the vehicle width direction, "up" means the upper side in the vertical direction, and "down" means the lower side in the vertical direction. Note that the posture of the vehicle lamp 1 is not limited to the illustrated state.

[0012] The vehicle lamp 1 includes a plurality of first light sources 2, a plurality of second light sources 4, and an optical member 6. The vehicle lamp 1 also includes a lamp body and a light-transmitting cover (outer lens) (not shown). The plurality of first light sources 2, the plurality of second light sources 4, and the optical member 6 are housed in a lamp chamber formed by the lamp body and the light-transmitting cover.

[0013] Each of the first light sources 2 and each of the second light sources 4 are, for example, composed of LEDs (light-emitting diodes). Note that each of the first light sources 2 and each of the second light sources 4 may be semiconductor light-emitting elements other than LEDs, such as LDs (laser diodes), organic or inorganic ELs (electroluminescence). Further, each of the first light sources 2 and each of the second light sources 4 may be an incandescent bulb, a halogen lamp, a discharge bulb, or the like.

[0014] The plurality of first light sources 2 and the plurality of second light sources 4 are mounted on a common control board 8 as an example. The control board 8 of the present embodiment is long in the vehicle width direction. The control board 8 controls the lighting and extinguishing of each of the first light sources 2 and each of the second light sources 4. The control board 8 has a hardware configuration (not shown) such as elements and circuits including a CPU and a memory of a computer. Further, it has a software configuration realized by a computer program or the like. The control board 8 is mounted on the lamp body.

[0015] The optical member 6 is plate-shaped and fixed to the light source mounting surface of the control board 8. The optical member 6 has a plurality of diffusion portions 10 and a plurality of openings 12. The optical member 6 is composed of a resin such as polycarbonate, polypropylene, acrylic, ASA (acrylonitrile-styrene-acrylate), or ABS (acrylonitrile-butadiene-styrene), for example. Further, the optical member 6 of the present embodiment is composed of an inner lens portion 14 and a reflector portion 16. The inner lens portion 14 is disposed closer to the front side of the lamp than the reflector portion 16 and is attached to the surface of the reflector portion 16 facing the front side of the lamp.

[0016] The inner lens part 14 has a plurality of diffusion parts 10 and a support frame 18. Each diffusion part 10 has a box shape with an opening on the rear side of the lamp. When viewed from the front of the lamp, each diffusion part 10 is a rectangular shape that is long in the vehicle width direction. The support frame 18 is a rod-shaped body that extends in the vehicle width direction. Each diffusion part 10 is connected to the support frame 18 and thus connected to each other. In the present embodiment, the plurality of diffusion parts 10 are integrally molded products. That is, the plurality of diffusion parts 10 and the support frame 18 are integrally molded.

[0017] In the present disclosure, "integrally molded" means that each diffusion part 10 and the support frame 18, which were originally separate bodies, are not joined together by a known fixing method such as welding or adhesion, but rather each diffusion part 10 and the support frame 18 are formed into one member by a known molding process such as injection molding.

[0018] Each diffusion part 10 is arranged so as to cover the first light source 2 when viewed from the front of the lamp. In the present embodiment, each first light source 2 and each diffusion part 10 are associated with each other one-to-one, and each diffusion part 10 covers one first light source 2. Note that each diffusion part 10 may cover a plurality of first light sources 2. That is, each diffusion part 10 covers one or more first light sources 2. Also, the number of first light sources 2 covered by each diffusion part 10 may be different from each other.

[0019] Each diffusion part 10 can diffuse the light emitted from the first light source 2 that it covers. For example, each diffusion part 10 is made of a resin material that is translucent with respect to the light of the first light source 2, that is, a part of the light of the first light source 2 can pass through. This resin material is composed of, for example, a transparent resin base material and particles that are dispersed in the resin base material and have a refractive index different from that of the resin base material. The light transmittance of the translucent resin can be appropriately set based on experiments or simulations by the designer. When the plurality of diffusion parts 10 are integrally molded products, the entire inner lens part 14 is made of a translucent resin.

[0020] The light emitted from the first light source 2 is incident on at least the surface of the light fixture facing the front side of the diffusion part 10, and while being reflected by particles, it passes through the surface and irradiates the front of the light fixture. Therefore, the surface of each diffusion part 10 facing the front side of the light fixture constitutes a light diffusion surface. Instead of forming each diffusion part 10 with a translucent resin, the light of the first light source 2 can also be diffused by subjecting the surface of each diffusion part 10 made of a transparent resin to a roughening treatment such as embossing.

[0021] The reflector part 16 is a plate-like body that extends in a direction intersecting the front-rear direction of the light fixture. The reflector part 16 is long in the vehicle width direction and has an inclined edge part 16a at the end on the outer side in the vehicle width direction that is inclined so as to be positioned vertically upward as it goes toward the outer side in the vehicle width direction. Further, the reflector part 16 has a plurality of openings 12. The plurality of openings 12 are provided so as to penetrate the reflector part 16 in the front-rear direction of the light fixture. Each opening 12 is arranged so as to expose the second light source 4 when viewed from the front of the light fixture. In the present embodiment, each second light source 4 and each opening 12 are associated with each other one-to-one, and each opening 12 exposes one second light source 4. Note that each opening 12 may expose a plurality of second light sources 4. That is, each opening 12 exposes one or more second light sources 4. Also, the number of second light sources 4 exposed by each opening 12 may be different from each other.

[0022] Each second light source 4 can directly irradiate light forward of the lamp through each opening 12. Further, the reflector portion 16 of the present embodiment has a reflecting surface 20 that reflects the light of the second light source 4 around each opening 12. A part of the light emitted from each second light source 4 is reflected by the reflecting surface 20 and irradiated forward of the lamp. For example, the reflector portion 16 is made of the above-described translucent resin or transparent resin and has a metal film around each opening 12. And this metal film constitutes the reflecting surface 20. The metal film can be formed by vapor deposition of a metal such as aluminum. Further, the reflector portion 16 may be made of an opaque resin, and the surface around each opening 12 may directly constitute the reflecting surface 20. In addition, a metal film constituting the reflecting surface 20 may be provided on the reflector portion 16 made of an opaque resin. When the inner lens portion 14 and the reflector portion 16 are each made of the same resin material, the entire optical member 6 may be integrally formed.

[0023] Further, the reflector portion 16 also has a plurality of openings 22 for the first light source that overlap with the respective first light sources 2 when viewed from the front of the lamp. The plurality of openings 22 for the first light source are holes for preventing the light from each first light source 2 from advancing to each diffusing portion 10. In a state where the inner lens portion 14 and the reflector portion 16 are assembled to each other, each opening 22 for the first light source is covered by each diffusing portion 10. The light emitted from each first light source 2 passes through the reflector portion 16 through the opening 22 for the first light source and enters each diffusing portion 10.

[0024] The vehicle lamp 1 has a plurality of first light emitting portions 24 and a plurality of second light emitting portions 26. Each first light emitting portion 24 is formed by a combination of the first light source 2 and the diffusing portion 10. In the present embodiment, one combination of the first light source 2 and the diffusing portion 10 forms one first light emitting portion 24. The combination of the first light source 2 and the diffusing portion 10 is composed of one or more first light sources 2 and one diffusing portion 10. Note that a plurality of combinations of the first light source 2 and the diffusing portion 10 may be assembled to form one first light emitting portion 24. That is, each first light emitting portion 24 is formed by one or more combinations of the first light source 2 and the diffusing portion 10.

[0025] Each second light-emitting unit 26 is formed by a combination of a second light source 4 and an opening 12. In the present embodiment, one second light-emitting unit 26 is formed by one combination of the second light source 4 and the opening 12. The combination of the second light source 4 and the opening 12 is composed of one or more second light sources 4 and one opening 12. Note that a plurality of combinations of the second light source 4 and the opening 12 may be assembled to form one second light-emitting unit 26. That is, each second light-emitting unit 26 is formed by one or more combinations of the second light source 4 and the opening 12. Further, in the present embodiment, the optical member 6 includes a reflecting surface 20. Therefore, each second light-emitting unit 26 is formed by the second light source 4, the opening 12, and the reflecting surface 20.

[0026] At least a part of the plurality of first light-emitting units 24 and at least a part of the plurality of second light-emitting units 26 are alternately arranged. In the present embodiment, the plurality of first light-emitting units 24 are arranged in a zigzag pattern in a plane intersecting the front-rear direction of the lamp. Similarly, the plurality of second light-emitting units 26 are also arranged in a zigzag pattern in a plane intersecting the front-rear direction of the lamp. Further, the plurality of first light-emitting units 24 arranged in a zigzag pattern and the plurality of second light-emitting units 26 arranged in a zigzag pattern are combined. That is, a second light-emitting unit 26 is arranged between adjacent first light-emitting units 24. Alternatively, a first light-emitting unit 24 is arranged between adjacent second light-emitting units 26. Therefore, the plurality of first light-emitting units 24 and the plurality of second light-emitting units 26 are arranged in a checkered pattern.

[0027] Viewed differently, the vehicle lamp 1 of the present embodiment has a structure in which horizontally long light-emitting lines in which the first light-emitting units 24 and the second light-emitting units 26 are alternately arranged in the vehicle width direction are stacked vertically in a plurality. Adjacent horizontally long light-emitting lines are arranged such that the first light-emitting units 24 of one horizontally long light-emitting line and the second light-emitting units 26 of the other horizontally long light-emitting line are aligned. Alternatively, the vehicle lamp 1 has a structure in which vertically long light-emitting lines in which the first light-emitting units 24 and the second light-emitting units 26 are alternately arranged in the vertical direction are arranged in a plurality in the vehicle width direction. Adjacent vertically long light-emitting lines are arranged such that the first light-emitting units 24 of one vertically long light-emitting line and the second light-emitting units 26 of the other vertically long light-emitting line are aligned.

[0028] Note that the number of horizontal light-emitting lines and vertical light-emitting lines can be set as appropriate. For example, the vehicle lamp 1 may have only one horizontal light-emitting line or only one vertical light-emitting line. Also, the number of the first light-emitting portions 24 and the second light-emitting portions 26 included in each horizontal light-emitting line, as well as the number of the first light-emitting portions 24 and the second light-emitting portions 26 included in each vertical light-emitting line, can be set as appropriate.

[0029] FIG. 3(A) is a photograph of the vehicle lamp 1 in a state where both the first light source 2 and the second light source 4 are not lit. FIG. 3(B) is a photograph of the vehicle lamp 1 in a state where only the first light source 2 is lit. FIG. 3(C) is a photograph of the vehicle lamp 1 in a state where both the first light source 2 and the second light source 4 are lit. Note that in the vehicle lamp 1 shown in FIGS. 3(A) to 3(C), as an example, the light diffusion surfaces of the diffusion portions 10 in the left two columns are made of a white translucent resin, and the light diffusion surfaces of the remaining diffusion portions 10 are made of a dimpled surface. Also, the number of the first light-emitting portions 24 and the second light-emitting portions 26 is slightly different from that shown in FIGS. 1 and 2.

[0030] As shown in FIG. 3(A), in a state where both the first light source 2 and the second light source 4 are not lit, a checkered pattern composed of a plurality of diffusion portions 10 and a plurality of openings 12 is visible. As shown in FIG. 3(B), in a state where only the first light source 2 is lit, a staggered pattern of light emission by the plurality of first light-emitting portions 24 is visible. As shown in FIG. 3(C), in a state where both the first light source 2 and the second light source 4 are lit, light emission of the entire lamp by the plurality of first light-emitting portions 24 and the plurality of second light-emitting portions 26 is visible.

[0031] The vehicle lamp 1 can exhibit a first lamp function by the plurality of first light-emitting portions 24 and can exhibit a second lamp function different from the first lamp function by the plurality of first light-emitting portions 24 and the plurality of second light-emitting portions 26. As an example, the first lamp function is a tail lamp function, and the second lamp function is a stop lamp function. Therefore, the vehicle lamp 1 can emit light in a staggered pattern to exhibit the tail lamp function and can emit light as a whole to exhibit the stop lamp function.

[0032] In addition, known lighting functions such as a tail lamp, a stop lamp, a turn lamp, a clearance lamp, and a rear fog lamp can be appropriately assigned to the first lighting function and the second lighting function. Further, the vehicle lamp 1 may be used as a headlamp. In this case, known lighting functions such as a low beam, a high beam, a turn lamp, a positioning lamp, a daytime running lamp, and a fog lamp can be appropriately assigned to the first lighting function and the second lighting function. Further, depending on the first lighting function and the second lighting function, the types (the amount and color of emitted light) of the first light source 2 and the second light source 4 can be appropriately selected.

[0033] Further, the vehicle lamp 1 can also be configured to exhibit the first lighting function with a plurality of first light emitting portions 24 and exhibit the second lighting function with a plurality of second light emitting portions 26. In this case, the vehicle lamp 1 can emit light in a staggered pattern to exhibit the first lighting function, and emit light in a staggered pattern at a position shifted from the light emitting position when exhibiting the first lighting function to exhibit the second lighting function.

[0034] As described above, the vehicle lamp 1 according to the present embodiment includes a plurality of first light emitting portions 24 and a plurality of second light emitting portions 26. Each first light emitting portion 24 is formed by one or more sets of the first light source 2 and the diffusing portion 10, and each second light emitting portion 26 is formed by one or more sets of the second light source 4 and the opening portion 12. And at least a part of the plurality of first light emitting portions 24 and at least a part of the plurality of second light emitting portions 26 are alternately arranged.

[0035] In each first light-emitting unit 24, the light of the first light source 2 is diffused by the diffusion unit 10 and irradiated forward of the lamp. On the other hand, in each second light-emitting unit 26, the light of the second light source 4 is directly irradiated forward of the lamp from the opening 12. Further, when the optical member 6 has the reflecting surface 20, a part of the light of the second light source 4 is reflected by the reflecting surface 20 and irradiated forward of the lamp. Therefore, drivers of other vehicles, pedestrians, etc. will visually recognize the light-emitting units with different lighting patterns when the first light source 2 is lit and when the second light source 4 is lit. Further, they will visually recognize a state in which the light-emitting units with different lighting patterns are arranged alternately. Furthermore, when the first light source 2 and the second light source 4 are turned off, drivers of other vehicles, pedestrians, etc. will visually recognize a pattern in which the plurality of diffusion units 10 and the plurality of openings 12 are arranged alternately. Thereby, the conspicuity of the vehicle lamp 1 can be enhanced and the self-vehicle display function can be improved.

[0036] Further, in the present embodiment, the plurality of first light-emitting units 24 and the plurality of second light-emitting units 26 are arranged in a checkered pattern. Thereby, when the first light source 2 and the second light source 4 are turned off, the checkered pattern of the diffusion unit 10 and the opening 12 can be visually recognized by drivers of other vehicles, pedestrians, etc. Further, when only the first light source 2 is lit and when only the second light source 4 is lit, a staggered lighting can be realized respectively. Thereby, since the conspicuity of the vehicle lamp 1 is further enhanced, the self-vehicle display function can be further improved.

[0037] Further, the vehicle lamp 1 of the present embodiment exhibits the first lamp function only with the plurality of first light-emitting units 24, and exhibits a second lamp function different from the first lamp function with the plurality of first light-emitting units 24 and the plurality of second light-emitting units 26. In this case, the light-emitting shape can be made different when the vehicle lamp 1 exhibits the first lamp function and when it exhibits the second lamp function. Thereby, since the conspicuity of the vehicle lamp 1 is further enhanced, the self-vehicle display function of the vehicle lamp 1 can be further enhanced. Further, by exhibiting the second lamp function with the plurality of first light-emitting units 24 and the plurality of second light-emitting units 26, the light-emitting area when exhibiting the second lamp function can be increased. Also by this, the self-vehicle display function of the vehicle lamp 1 can be enhanced.

[0038] In addition, the vehicle lamp 1 can also exhibit the first lamp function only with a plurality of first light emitting portions 24 and exhibit the second lamp function only with a plurality of second light emitting portions 26. In this case, the light emitting positions can be shifted with a similar light emitting shape when the first lamp function is exhibited and when the second lamp function is exhibited. Thereby, since the visibility of the vehicle lamp 1 is further enhanced, the self-vehicle display function of the vehicle lamp 1 can be further improved.

[0039] In addition, the optical member 6 of the present embodiment has a reflecting surface 20 around each opening 12. And each second light emitting portion 26 is formed by the second light source 4, the opening 12, and the reflecting surface 20. Thereby, the light emitting area of each second light emitting portion 26 can be increased. Therefore, since the visibility of the vehicle lamp 1 is further enhanced, the self-vehicle display function can be further improved.

[0040] As an example, the optical member 6 is made of a translucent resin, a metal film laminated on the surface of the translucent resin constitutes the reflecting surface 20, and the translucent resin itself constitutes the diffusing portion 10. By forming the entire optical member 6 of a translucent resin, the inner lens portion 14 and the reflector portion 16 can be integrally formed. Thereby, the number of parts of the vehicle lamp 1 can be reduced, and the manufacturing process of the vehicle lamp 1 can be simplified. Further, by providing a metal film that functions as the reflecting surface 20, even when the optical member 6 is made of a translucent resin, the light reflectance of the reflecting surface 20 can be increased.

[0041] In addition, by forming the diffusing portion 10 of a translucent resin, uniform surface light emission can be realized more easily than in the case where the diffusing portion 10 is subjected to a roughening process such as embossing. Further, since the translucent resin itself can be used as a light diffusing surface, the manufacturing process of the vehicle lamp 1 can be simplified as compared with the case where a roughening process such as embossing is performed. As an example, the plurality of diffusing portions 10 are integrally molded products. Thereby, the number of parts of the vehicle lamp 1 can be reduced, and the manufacturing process of the vehicle lamp 1 can be simplified.

[0042] The embodiments of the present invention have been described in detail above. The above-described embodiments are merely specific examples for implementing the present invention. The content of the embodiments does not limit the technical scope of the present invention, and many design changes such as component changes, additions, deletions, etc. are possible without departing from the inventive concept defined in the claims. The new embodiments with design changes have the combined effects of the combined embodiments and the respective modifications. In the above-described embodiments, with regard to the content that allows such design changes, expressions such as "in this embodiment" and "in this embodiment" are used for emphasis, but design changes are also allowed for the content without such expressions. Any combination of the above components is also effective as an aspect of the present invention. The hatching attached to the cross-section of the drawing does not limit the material of the object to which the hatching is attached.

[0043] (Modification Example 1) FIG. 4 is a perspective view of the optical member 6 according to Modification Example 1. In the optical member 6 of this modification example, the brightness is different between the surfaces around each opening 12 and each diffusion part 10. For example, the inner lens part 14 is made of a white translucent resin or a transparent resin. When the inner lens part 14 is made of a transparent resin, the surface of the diffusion part 10 is roughened. On the other hand, the reflector part 16 is made of a black resin, and the surface around the opening 12 is the black resin itself. Alternatively, the surface around the opening 12 in the reflector part 16 is painted black. Thereby, the brightness of each diffusion part 10 becomes higher than the brightness of the surface around each opening 12. As a result, the checkered pattern of the vehicle lamp 1 in the state where both the first light source 2 and the second light source 4 are not lit can be made clearer. Therefore, the visibility of the vehicle lamp 1 is further enhanced, and the self-vehicle display function can be further improved.

[0044] Note that, for example, by forming the diffusion part 10 with a half mirror vapor deposition film, forming the reflector part 16 with a white resin, or applying white paint to the surface around the opening part 12, the brightness of the surface around each opening part 12 can be made higher than that of each diffusion part 10. The brightness difference between the surface around each opening part 12 and each diffusion part 10 may be realized by a combination of colors other than white and black. The degree of the brightness difference can be appropriately set by the designer in consideration of the degree of eye-catching property and the like.

[0045] (Modification Examples 2 to 4) FIG. 5(A) is a perspective view of the optical member 6 according to Modification Example 2. FIG. 5(B) is a perspective view of the optical member 6 according to Modification Example 3. FIG. 5(C) is a perspective view of the optical member 6 according to Modification Example 4. The shapes of the inner lens parts 14 of the optical members 6 in Modification Examples 2 to 4 are different from each other.

[0046] As shown in FIG. 5(A), in Modification Example 2, the diffusion part 10 and the support frame 18 protrude more forward of the lamp than in the embodiment. As shown in FIG. 5(B), in Modification Example 3, the amount of protrusion of the diffusion part 10 forward of the lamp is about the same as that in the embodiment, but the amount of protrusion of the support frame 18 forward of the lamp is small. Also, each diffusion part 10 in Modification Examples 2 and 3 is substantially square when viewed from the front of the lamp. Further, in Modification Examples 2 and 3, the number of diffusion parts 10 is larger and the individual size is smaller than in the embodiment.

[0047] As shown in FIG. 5(C), the diffusion part 10 of Modification Example 4 is inclined such that the outer and inner side surfaces in the vehicle width direction are substantially parallel to the inclined edge part 16a. That is, each side surface is inclined so as to be located more outward in the vehicle width direction as it goes upward in the vertical direction. Thus, various variations can be provided in the shape of the optical member 6. Thereby, it is easy to improve the eye-catching property of the vehicle lamp 1.

[0048] (Modification Example 5) FIG. 6(A) is an exploded perspective view of the vehicle lamp 1 according to Modification 5. FIG. 6(B) is an exploded perspective view of the vehicle lamp 1 according to the embodiment. FIG. 6(C) is a photograph of the vehicle lamp 1 according to Modification 5 in a state where only the first light source 2 is lit. FIG. 6(D) is a photograph of the vehicle lamp 1 according to the embodiment in a state where only the first light source 2 is lit. FIG. 6(E) is a photograph of the vehicle lamp 1 according to Modification 5 in a state where both the first light source 2 and the second light source 4 are lit. FIG. 6(F) is a photograph of the vehicle lamp 1 according to the embodiment in a state where both the first light source 2 and the second light source 4 are lit.

[0049] As shown in FIG. 6(A), in this modification, the reflector portion 16, the inner lens portion 14, and the control board 8 are arranged in this order from the front side of the lamp, and each is assembled to one another. Each diffusion portion 10 is inserted into each first light source opening 22. On the other hand, as shown in FIG. 6(B) (see also FIG. 2), in the embodiment, the inner lens portion 14, the reflector portion 16, and the control board 8 are arranged in this order from the front side of the lamp, and each is assembled to one another.

[0050] Therefore, in this modification, since the support frame 18 is arranged on the rear side of the lamp with respect to the reflector portion 16, it cannot be visually recognized from the front of the lamp. On the other hand, in the embodiment, since the support frame 18 is arranged on the front side of the lamp with respect to the reflector portion 16, it can be visually recognized from the front of the lamp. And depending on its shape, at least the light of the first light source 2 can enter the support frame 18 and emit light together with the diffusion portion 10.

[0051] Therefore, as shown in FIGS. 6(C) and 6(D), when only the first light source 2 is lit, the vehicle lamp 1 of this modified example has a clearer contour of each first light emitting portion 24 than the vehicle lamp 1 of the embodiment. Therefore, a clearer checkered pattern of light emission can be visually recognized. Further, as shown in FIGS. 6(E) and 6(F), even when the first light source 2 and the second light source 4 are lit, the vehicle lamp 1 of this modified example has a clearer contour of each first light emitting portion 24 than the vehicle lamp 1 of the embodiment. Therefore, a clearer plaid pattern of light emission can be visually recognized. Thus, by changing the positions of the inner lens portion 14 and the reflector portion 16 in the front-rear direction of the lamp, different light emission modes can be realized.
