Detailed Description
The present invention will be described below based on preferred embodiments with reference to the accompanying drawings. The embodiments are not intended to limit the present invention but to exemplify the present invention, and all the features or combinations thereof described in the embodiments are not necessarily essential to the present invention. The same or equivalent constituent elements, members, and processes shown in the respective drawings are denoted by the same reference numerals, and overlapping descriptions are appropriately omitted. The scale and shape of each portion shown in each drawing are appropriately set for ease of description, and are not to be construed as limiting unless otherwise specified. In the present specification and claims, the terms "first", "second", and the like are used for distinguishing a certain structure from other structures without any order or importance unless otherwise specified. In the drawings, a part of a member which is not important in describing the embodiment is omitted.
Fig. 1 is a perspective view of a vehicle lamp 1 according to an embodiment. Fig. 2 is an exploded perspective view of the vehicle lamp 1. As an example, the vehicle lamp 1 is a rear lamp disposed at the rear of a vehicle. In the drawings, "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 inside in the vehicle width direction, "outer" means the outside in the vehicle width direction, "upper" means the upper side in the vertical direction, and "lower" means the lower side in the vertical direction. The posture of the vehicle lamp 1 is not limited to the illustrated state.
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 includes a lamp body and a light-transmitting cover (outer lens), which are 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 a lamp body and a translucent cover.
Each of the first light sources 2 and each of the second light sources 4 is formed of, for example, an LED (light emitting diode). 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 LD (laser diode) and organic or inorganic EL (electroluminescence). The first light sources 2 and the second light sources 4 may be incandescent bulbs, halogen lamps, discharge bulbs, or the like.
For example, the plurality of first light sources 2 and the plurality of second light sources 4 are mounted on a common control board 8. The control board 8 of the present embodiment is long in the vehicle width direction. The control board 8 controls turning on and off of the first light sources 2 and the second light sources 4. The control board 8 has a hardware configuration (not shown) such as elements and circuits represented by a CPU and a memory of a computer. In addition, the present invention has a software configuration realized by a computer program or the like. The control board 8 is mounted on the lamp body.
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 diffusing portions 10 and a plurality of openings 12. The optical member 6 is made of a resin such as polycarbonate, polypropylene, acrylic, ASA (acrylonitrile-styrene-acrylate), ABS (acrylonitrile-butadiene-styrene), or the like. 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 on the front side of the lamp with respect to the reflector portion 16, and is attached to the surface of the reflector portion 16 facing the front side of the lamp.
The inner lens portion 14 includes a plurality of diffusion portions 10 and a support frame 18. Each diffuser 10 has a box shape having an opening on the lamp rear side. Each diffuser portion 10 is rectangular in shape that is long in the vehicle width direction when viewed from the front of the lamp. The support frame 18 is a rod-shaped body extending in the vehicle width direction. The respective diffusing portions 10 are connected to each other by being connected to a support frame 18. In the present embodiment, the plurality of diffusing portions 10 are integrally formed pieces. That is, the plurality of diffusing portions 10 are integrally formed with the support frame 18.
The term "integrally molded" in the present disclosure means that the diffuser portions 10 and the support frames 18, which are originally separate bodies, are not formed as one member as a result of being fixed to each other by a known fixing method such as welding or bonding, but the diffuser portions 10 and the support frames 18 are formed in one member by a known molding process such as injection molding.
Each diffuser portion 10 is disposed 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 corresponds to each diffusion portion 10 one-to-one, and each diffusion portion 10 covers one first light source 2. Each diffusion portion 10 may cover a plurality of first light sources 2. That is, each diffusion portion 10 covers one or more first light sources 2. The number of the first light sources 2 covered by each diffusion portion 10 may be different from each other.
Each diffusion portion 10 can diffuse the light emitted from the covered first light source 2. For example, each diffuser 10 is made of a resin material that is translucent to the light of the first light source 2, that is, allows a part of the light of the first light source 2 to pass through. The resin material is composed of, for example, a transparent resin base material and particles dispersed in the resin base material and having a refractive index different from that of the resin base material. The light transmittance of the translucent resin can be set as appropriate based on experiments and simulations performed by a designer. When the plurality of diffusing portions 10 are formed as an integral body, the entire inner lens portion 14 is made of a translucent resin.
The light emitted from the first light source 2 enters at least a surface of the diffusion portion 10 facing the front side of the lamp, and is reflected by the particles, transmitted through the surface, and irradiated to the front side of the lamp. Therefore, the surface of each diffusion portion 10 facing the front side of the lamp constitutes a light diffusion surface. Instead of forming the diffusing portions 10 of a translucent resin, the light from the first light source 2 can be diffused by roughening the surfaces of the diffusing portions 10 of a translucent resin by texturing.
The reflector portion 16 is a plate-like body that expands in a direction intersecting the front-rear direction of the lamp. The reflector portion 16 is long in the vehicle width direction, and has an inclined edge portion 16a inclined so as to be positioned more upward in the vertical direction as it goes outward in the vehicle width direction at an end portion on the outer side in the vehicle width direction. The reflector 16 has a plurality of openings 12. The plurality of openings 12 are provided to penetrate the reflector 16 in the front-rear direction of the lamp. Each opening 12 is disposed so as to expose the second light source 4 when viewed from the front of the lamp. In the present embodiment, each second light source 4 corresponds to each opening 12 one-to-one, and each opening 12 exposes one second light source 4. Each of the openings 12 may expose a plurality of second light sources 4. That is, each opening 12 exposes one or more second light sources 4. The number of the second light sources 4 exposed to each opening 12 may be different from each other.
Each second light source 4 can directly irradiate light to the front of the lamp through each opening 12. The reflector 16 of the present embodiment has a reflection surface 20 for reflecting the light of the second light source 4 around each opening 12. Part of the light emitted from each second light source 4 is reflected by the reflecting surface 20 and irradiated to the front of the lamp. For example, the reflector 16 is made of the translucent resin or the transparent resin described above, and has a metal film around each opening 12. The metal film constitutes the reflecting surface 20. The metal film can be formed by vapor deposition of a metal such as aluminum. The reflector 16 may be made of an opaque resin, and the surface around each opening 12 may directly constitute the reflecting surface 20. The reflector 16 made of an opaque resin may be provided with a metal film constituting the reflecting surface 20. When the inner lens portion 14 and the reflector portion 16 are made of the same resin material, the entire optical member 6 may be integrally molded.
The reflector portion 16 further includes a plurality of first light source openings 22 that overlap the first light sources 2 when viewed from the front of the lamp. The plurality of first light source openings 22 are holes for preventing light from entering from the first light sources 2 into the diffusion sections 10. In a state where the inner lens portion 14 and the reflector portion 16 are assembled with each other, the respective first light source apertures 22 are covered by the respective diffusion portions 10. The light emitted from each first light source 2 passes through the reflector 16 via the first light source opening 22 and enters each diffusion 10.
The vehicle lamp 1 has a plurality of first light emitting portions 24 and a plurality of second light emitting portions 26. Each of the first light-emitting portions 24 is formed by a combination of the first light source 2 and the diffuser 10. In the present embodiment, one first light-emitting portion 24 is formed by one combination of the first light source 2 and the diffusion portion 10. The combination of the first light source 2 and the diffuser 10 is composed of one or more first light sources 2 and one diffuser 10. A plurality of combinations of the first light sources 2 and the diffusion sections 10 may be combined to form one first light-emitting section 24. That is, each of the first light-emitting portions 24 is formed by a combination of one or more first light sources 2 and diffusion portions 10.
Each second light emitting unit 26 is formed by a combination of the second light source 4 and the 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. A plurality of combinations of the second light source 4 and the opening 12 may be combined to form one second light emitting unit 26. That is, each second light emitting unit 26 is formed by a combination of one or more second light sources 4 and the opening 12. In the present embodiment, the optical member 6 includes the 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.
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. In the present embodiment, the plurality of first light-emitting portions 24 are arranged in a staggered manner in a plane intersecting the front-rear direction of the lamp. Similarly, the second light emitting units 26 are also arranged in a staggered manner in a plane intersecting the front-rear direction of the lamp. In addition, the plurality of first light-emitting portions 24 arranged in a staggered manner and the plurality of second light-emitting portions 26 arranged in a staggered manner are combined. That is, the second light-emitting portion 26 is disposed between the adjacent first light-emitting portions 24. Alternatively, the first light-emitting portion 24 is disposed between the adjacent second light-emitting portions 26. Thus, the plurality of first light-emitting portions 24 and the plurality of second light-emitting portions 26 are arranged in a checkered pattern.
In other words, the vehicle lamp 1 of the present embodiment has a structure in which a plurality of horizontally long light-emitting lines, in which the first light-emitting portions 24 and the second light-emitting portions 26 are alternately arranged in the vehicle width direction, are stacked vertically. The adjacent laterally long light emitting lines are arranged such that the first light emitting portion 24 of one laterally long light emitting line and the second light emitting portion 26 of the other laterally long light emitting line are arranged in parallel. Alternatively, the vehicle lamp 1 has a structure in which a plurality of longitudinal light emitting lines, in which the first light emitting portions 24 and the second light emitting portions 26 are alternately arranged in the vertical direction, are arranged in the vehicle width direction. The adjacent longitudinal light emitting wires are arranged such that the first light emitting portion 24 of one longitudinal light emitting wire and the second light emitting portion 26 of the other longitudinal light emitting wire are juxtaposed.
The number of the horizontally long light-emitting lines and the vertically long light-emitting lines may be set as appropriate. For example, the vehicle lamp 1 may have only one horizontally long light emitting line or only one vertically long light emitting line. The number of the first light-emitting units 24 and the second light-emitting units 26 included in each of the horizontally long light-emitting lines and the number of the first light-emitting units 24 and the second light-emitting units 26 included in each of the vertically long light-emitting lines can be set as appropriate.
Fig. 3 (a) is a diagram of the vehicle lamp 1 in which both the first light source 2 and the second light source 4 are not lit. Fig. 3 (B) is a diagram of the vehicle lamp 1 in which only the first light source 2 is in a lit state. Fig. 3 (C) is a diagram of the vehicle lamp 1 in which the first light source 2 and the second light source 4 are both in an illuminated state. In the vehicle lamp 1 shown in fig. 3 (a) to 3 (C), the light diffusing surfaces of the diffusing portions 10 in the two left rows are formed of white translucent resin, and the light diffusing surfaces of the remaining diffusing portions 10 are formed of textured surfaces, as an example. The number of the first light-emitting portions 24 and the second light-emitting portions 26 is slightly different from that shown in fig. 1 and 2.
As shown in fig. 3 (a), when both the first light source 2 and the second light source 4 are not lit, a checkered pattern including the plurality of diffusion portions 10 and the plurality of openings 12 is visually recognized. As shown in fig. 3 (B), when only the first light source 2 is turned on, the light emission of the staggered pattern formed by the plurality of first light-emitting portions 24 is visually recognized. As shown in fig. 3 (C), in a state where both the first light source 2 and the second light source 4 are lit, the light emission of the entire lamp formed by the plurality of first light-emitting portions 24 and the plurality of second light-emitting portions 26 is visually recognized.
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 light fixture function is a tail light function and the second light fixture function is a stop light function. Therefore, the vehicle lamp 1 can emit light in a staggered pattern to function as a tail lamp, and can emit light as a whole to function as a stop lamp.
Note that known lamp functions such as a tail lamp, a stop lamp, a turn signal lamp, a width indicator lamp, and a rear fog lamp can be appropriately assigned to the first lamp function and the second lamp function. In addition, the vehicle lamp 1 may also be used as a headlamp. In this case, known lamp functions such as low beam, high beam, turn signal, position signal, daytime running light, and fog light can be appropriately assigned to the first lamp function and the second lamp function. Further, the types of the first light source 2 and the second light source 4 (the amount and the color of the emitted light) can be appropriately selected according to the first lighting function and the second lighting function.
The vehicle lamp 1 may be configured such that the plurality of first light emitting portions 24 perform the first lamp function and the plurality of second light emitting portions 26 perform the second lamp function. In this case, the vehicle lamp 1 can emit light in a staggered pattern to exhibit the first lamp function, and can emit light in a staggered pattern at a position shifted from the light emission position at the time of exhibiting the first lamp function to exhibit the second lamp function.
As described above, the vehicle lamp 1 according to the present embodiment includes the plurality of first light emission portions 24 and the plurality of second light emission portions 26. Each first light emitting portion 24 is formed by a combination of one or more first light sources 2 and the diffusing portion 10, and each second light emitting portion 26 is formed by a combination of one or more second light sources 4 and the opening portion 12. 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.
In each first light emitting portion 24, the light from the first light source 2 is diffused by the diffusion portion 10 and is emitted to the front of the lamp. On the other hand, in each of the second light emitting units 26, the light from the second light source 4 is directly emitted from the opening 12 toward the front of the lamp. In addition, when the optical member 6 has the reflecting surface 20, part of the light of the second light source 4 is reflected by the reflecting surface 20 and is irradiated to the front of the lamp. Therefore, the driver of another vehicle, a pedestrian, or the like visually recognizes the light emitting portions of different light emission modes at the time of lighting the first light source 2 and at the time of lighting the second light source 4. Further, the state in which the light emitting sections of different light emitting systems are alternately arranged is visually recognized. Further, when the first light source 2 and the second light source 4 are turned off, the driver, the pedestrian, or the like of another vehicle visually recognizes a pattern in which the plurality of diffusing portions 10 and the plurality of openings 12 are alternately arranged. This can improve the visibility of the vehicle lamp 1 and improve the display function of the vehicle.
In the present embodiment, the plurality of first light-emitting portions 24 and the plurality of second light-emitting portions 26 are arranged in a checkered pattern. Thus, when the first light source 2 and the second light source 4 are turned off, the driver, the pedestrian, or the like of another vehicle can visually recognize the checkered pattern of the diffusion portion 10 and the opening portion 12. In addition, when only the first light source 2 is turned on and when only the second light source 4 is turned on, light emission in the staggered pattern can be realized. This further improves the visibility of the vehicle lamp 1, and thus the vehicle display function can be further improved.
In the vehicle lamp 1 of the present embodiment, the plurality of first light emission portions 24 only serve as the first lamp function, and the plurality of first light emission portions 24 and the plurality of second light emission portions 26 serve as the second lamp function different from the first lamp function. In this case, the light emission shapes can be made different between when the vehicle lamp 1 performs the first lighting function and when the vehicle lamp 1 performs the second lighting function. This further improves the visibility of the vehicle lamp 1, and therefore the vehicle display function of the vehicle lamp 1 can be further improved. Further, the plurality of first light emitting units 24 and the plurality of second light emitting units 26 function as a second lamp, and thus the light emitting area when the second lamp function is performed can be increased. This also improves the display function of the vehicle lamp 1.
In the vehicle lamp 1, the first lamp function may be performed only by the plurality of first light emitting portions 24, and the second lamp function may be performed only by the plurality of second light emitting portions 26. In this case, the light emission positions can be shifted in a similar light emission shape between when the first lamp function is performed and when the second lamp function is performed. This further improves the visibility of the vehicle lamp 1, and therefore the vehicle display function of the vehicle lamp 1 can be further improved.
The optical member 6 of the present embodiment has a reflection surface 20 around each opening 12. Each second light emitting unit 26 is formed by the second light source 4, the opening 12, and the reflecting surface 20. This can increase the light-emitting area of each second light-emitting unit 26. Therefore, the visibility of the vehicle lamp 1 is further improved, and thus the vehicle display function can be further improved.
In addition, as an example, the optical member 6 is made of a translucent resin, the metal film laminated on the surface of the translucent resin constitutes the reflection surface 20, and the translucent resin itself constitutes the diffusion portion 10. By constituting the entire optical member 6 with a translucent resin, the inner lens portion 14 and the reflector portion 16 can be integrally molded. This can reduce the number of components of the vehicle lamp 1, and simplify the manufacturing process of the vehicle lamp 1. Further, by providing the metal film functioning 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 improved.
Further, by forming the diffusing parts 10 of a translucent resin, uniform surface emission can be achieved more easily than when roughening treatment such as texturing is performed on the diffusing parts 10. Further, since the translucent resin itself can be used as the light diffusing surface, the manufacturing process of the vehicle lamp 1 can be simplified as compared with the case where the roughening treatment such as the texturing is performed. In addition, the plurality of diffusion portions 10 are, for example, integrally formed pieces. This can reduce the number of components of the vehicle lamp 1, and simplify the manufacturing process of the vehicle lamp 1.
The embodiments of the present invention have been described in detail above. The above embodiments are merely specific examples for carrying out the present invention. The technical scope of the present invention is not limited to the contents of the embodiments, and various design changes such as changes, additions, and deletions of the components can be made without departing from the scope of the idea of the present invention defined in the claims. The new embodiment to which the design change is applied has both the combined embodiments and the effects of the modifications. In the above-described embodiment, the contents that can be subjected to such a design change are highlighted with a mark such as "in the present embodiment" or "in the present embodiment", but the design change is permitted even if the contents do not have such a mark. Any combination of the above components is also effective as an aspect of the present invention. The hatching indicated in the cross section of the drawings does not limit the material of the object marked with the hatching.
(modification 1)
Fig. 4 is a perspective view of an optical member 6 according to modification 1. The optical member 6 of the present modification has a different luminance on the surface around each opening 12 from that of each diffusion 10. For example, the inner lens portion 14 is made of white translucent resin or transparent resin. When the inner lens portion 14 is made of a transparent resin, the surface of the diffuser portion 10 is roughened. On the other hand, the reflector 16 is made of black resin, and the surface around the opening 12 is made of black resin itself. Alternatively, the surface of the reflector 16 around the opening 12 is black-painted. Thus, the brightness of each diffusion portion 10 is higher than the brightness of the surface around each opening 12. As a result, the checkered pattern of the vehicle lamp 1 in which 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 improved, and the vehicle display function can be further improved.
For example, the diffusion portions 10 are formed of a half mirror deposited film, the reflector portions 16 are formed of a white resin, or the surfaces around the openings 12 are coated with a white paint, whereby the brightness of the surfaces around the openings 12 can be made higher than the brightness of the diffusion portions 10. The luminance difference between the surface around each opening 12 and each diffusion 10 can be realized by a combination of colors other than white and black. The degree of brightness difference can be set by the designer as appropriate in consideration of the degree of saliency and the like.
(modification examples 2 to 4)
Fig. 5 (a) is a perspective view of the optical member 6 according to modification 2. Fig. 5 (B) is a perspective view of the optical member 6 according to modification 3. Fig. 5 (C) is a perspective view of the optical member 6 according to modification 4. The shapes of the inner lens portions 14 of the optical members 6 of the modifications 2 to 4 are different from each other.
As shown in fig. 5 (a), in modification 2, the diffuser 10 and the support frame 18 protrude further toward the front of the lamp than in the embodiment. As shown in fig. 5 (B), in modification 3, the amount of projection of the diffuser 10 to the front of the lamp is the same as that of the embodiment, but the amount of projection of the support frame 18 to the front of the lamp is small. Each diffusion portion 10 of modification examples 2 and 3 has a substantially square shape when viewed from the front of the lamp. In modification 2 and modification 3, the number of diffusing portions 10 is larger than that in the embodiment, and the sizes of the diffusing portions are smaller.
As shown in fig. 5 (C), the diffusing portion 10 of modification 4 is inclined such that the vehicle-width-direction outer and inner side surfaces are substantially parallel to the inclined edge portion 16a. That is, each side surface is inclined so as to be located outward in the vehicle width direction as it goes upward in the vertical direction. In this way, the shape of the optical member 6 can be variously changed. This can easily improve the visibility of the vehicle lamp 1.

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 diagram of the vehicle lamp 1 according to modification 5 in which only the first light source 2 is in a lit state. Fig. 6 (D) is a diagram of the vehicle lamp 1 according to the embodiment in which only the first light source 2 is in a lit state. Fig. 6 (E) is a diagram of the vehicle lamp 1 according to modification 5 in which both the first light source 2 and the second light source 4 are in a lit state. Fig. 6 (F) is a diagram of the vehicle lamp 1 according to the embodiment in which both the first light source 2 and the second light source 4 are in the lit state.
As shown in fig. 6 (a), in the present 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 are assembled with each other. Each diffusion portion 10 is inserted into each first light source opening 22. On the other hand, as shown in fig. 6B (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 are assembled with each other.
Therefore, in the present modification, since the support frame 18 is disposed on the lamp rear side of the reflector portion 16, it cannot be visually recognized from the lamp front side. On the other hand, in the embodiment, since the support frame 18 is disposed on the lamp front side of the reflector portion 16, it can be visually recognized from the lamp front side. The support frame 18 is configured to allow at least the light from the first light source 2 to enter and emit light together with the diffusion portion 10.
Therefore, as shown in fig. 6 (C) and 6 (D), when only the first light source 2 is turned on, the outline of each first light emitting portion 24 is clearer in the vehicle lamp 1 of the present modification as compared with the vehicle lamp 1 of the embodiment. Therefore, the light emission of the interlaced pattern can be visually recognized more clearly. As shown in fig. 6 (E) and 6 (F), when the first light source 2 and the second light source 4 are turned on, the outline of each first light emitting portion 24 is clearer in the vehicle lamp 1 of the present modification as compared with the vehicle lamp 1 of the embodiment. Therefore, the light emission of the checkered pattern can be visually recognized more clearly. In this way, 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.
