[0009] Embodiments of vehicle lighting devices according to this disclosure will be described below with reference to the drawings. However, this embodiment does not limit the present invention. Furthermore, in the following embodiments, if there are multiple configuration examples, the elements of each configuration example can be combined as appropriate. The components in the following embodiments include those that are easily substituted or substantially identical to those that are easily substituted by those skilled in the art.

[0010] In this embodiment, the front and rear directions are defined as the directions when the device is mounted on a vehicle (vehicle-mounted state). For example, when mounted on the front of a vehicle, the front is forward and the rear is backward. When mounted on the rear of a vehicle, the rear is forward and the front is backward. When mounted on the side of a vehicle, the outside of the vehicle is forward and the inside of the vehicle is backward.

[0011] Figure 1 shows an example of the rear of a vehicle 1 according to this embodiment. As shown in Figure 1, the vehicle 1 comprises a vehicle body 2, a running gear 3, and vehicle lighting equipment 100. The vehicle body 2 has a driver's cab where the driver sits. The vehicle body 2 is supported by the running gear 3. The running gear 3 has wheels on which tires 4 are mounted, a steering device for changing the direction of travel of the vehicle 1, and a braking device for decelerating or stopping the running gear 3. The vehicle 1 comprises passenger doors provided on the sides of the vehicle body 2 and a back door 7 provided at the rear of the vehicle body 2. The passenger doors and the back door 7 are each movably supported by the vehicle body 2 via a hinge mechanism.

[0012] In this embodiment, the vehicle lights 100 are provided on the left and right sides of the rear of the vehicle body 2. In this embodiment, the vehicle lights 100 are provided at the rear of the vehicle body 2. Therefore, the rear side in the front-rear direction will be described as the front side of the vehicle lights 100, and the front side in the front-rear direction will be described as the rear side of the vehicle lights 100.

[0013] The vehicle lighting equipment 100 includes functional lamps. Examples of functional lamps include tail lamps located at the rear of the vehicle body 2 that illuminate in conjunction with the illumination of the headlights, stop lamps located at the rear of the vehicle body 2 that illuminate in conjunction with the operation of the brake device, and rear turn signal lamps located at the rear of the vehicle body 2 that illuminate to indicate the direction of travel of the vehicle 1 to the surroundings.

[0014] The vehicle lights 100 are, for example, positioned on the vehicle body 2 side. In this embodiment, the vehicle body 2 is a fixed part. The back door 7 is a movable part. The structure of the vehicle light 100 provided on the left side of the rear of the vehicle body 2 and the structure of the vehicle light 100 provided on the right side of the rear of the vehicle body 2 are symmetrical in the left-right direction and are substantially the same structure. The vehicle light 100 provided on the left side of the rear of the vehicle body 2 will be mainly described below, and the description of the vehicle light 100 provided on the right side of the rear of the vehicle body 2 will be simplified or omitted.

[0015] Figure 2 shows an example of a vehicle lighting fixture 100 according to this embodiment. Figure 2 shows a cross-sectional view as seen from above. The vehicle lighting fixture 100 shown in Figure 2 is, for example, a signal light such as a taillight. In this embodiment, the front direction is the rear direction, and the rear direction is the front direction. Also, the left direction is the outside of the vehicle, and the right direction is the inside of the vehicle. As shown in Figure 2, the vehicle lighting fixture 100 comprises an excitation light source 10, an optical member 20, a light conversion unit 30, an outer lens 40, and a housing 50.

[0016] The excitation light source 10 has a light source such as an LED or an organic EL. The excitation light source 10 emits light with a wavelength of 440 nm to 460 nm as excitation light in the forward direction. In this embodiment, multiple excitation light sources 10 (for example, three) are arranged in the left-right direction. Multiple excitation light sources 10 are mounted on a light source substrate 11. The light source substrate 11 is fixed to the housing 50.

[0017] The optical member 20 is disposed on the front side of the excitation light source 10. The optical member 20 guides the light emitted from the excitation light source 10 and emits it to the front side. In the present embodiment, the optical member 20 is provided, for example, for each excitation light source 10. Note that the optical member 20 may be provided across a plurality of excitation light sources 10. The optical member 20 has an incident surface 21 and an exit surface 22. The incident surface 21 faces the excitation light source 10 side. The light emitted from the excitation light source 10 enters the incident surface 21. The exit surface 22 emits the light incident from the incident surface 21. The optical member 20 is supported, for example, by the inner panel 60. The inner panel 60 is disposed in a lamp chamber formed by the housing 50.

[0018] The light conversion unit 30 converts the excitation light emitted from the optical member 20 to generate generated light and emits the generated light. The light conversion unit 30 includes a light emitting unit 31 and a support unit 32.

[0019] The light emitting unit 31 has a light emitting layer 33. The light emitting layer 33 generates generated light when irradiated with excitation light. The light emitting layer 33 emits the generated light from the emission surface 33a to the front side. The light emitting layer 33 includes, for example, particulate light emitters. As the light emitter, an organic material, a phosphor, or the like can be used. As the light emitter, for example, an organic material in which a guest material such as acetylacetone is doped at about 5% with respect to a host material such as polyvinylcarbazole can be used. In this case, the light emitting layer 33 emits red light as the generated light. The combination of the host material and the guest material is not limited to the above. Further, as the light emitter, for example, a semiconductor crystal having a diameter of about 2 nm to 10 nm such as a quantum dot may be used.

[0020] The support portion 32 is positioned on the back side of the light-emitting layer 33 and supports the light-emitting layer 33. The support portion 32 has a substrate 34. The substrate 34 is plate-shaped or sheet-shaped and transmits excitation light. The substrate 34 is positioned on the front side of the optical member 20 and on the back side of the light-emitting layer 33. Examples of light-transmitting resin materials for the substrate 34 include ABS (Acrylonitrile, Butadiene, Styrene), PC (Polycarbonate), PMMA (Polymethyl Methacrylate), PET (Polyethylene Terephthalate), and PVC (Polyvinyl Chloride).

[0021] The substrate 34 has a first surface 34a and a second surface 34b. The surface on the back side of the substrate 34 is the first surface 34a. Excitation light emitted from the optical member 20 is incident on this surface. The first surface 34a is arranged so as to intersect in the front direction. The second surface 34b emits excitation light. The surface on the front side of the substrate 34 is the second surface 34b. The light-emitting layer 33 is arranged on the second surface 34b. The second surface 34b is formed to be the same color as the light-emitting layer 33 when the vehicle light fixture 100 is viewed from the front.

[0022] Figures 3 and 4 schematically show an example of the light conversion unit 30. Figure 3 is a cross-sectional view similar to Figure 2, and Figure 4 is a view from the front. In Figure 3, the scale in the front-rear direction is enlarged compared to Figure 2.

[0023] As shown in Figures 3 and 4, in the light conversion unit 30, the support unit 32 has a same-color layer 35 formed on the second surface 34b of the substrate 34, which is the same color as the non-emitting light-emitting layer 33. Here, for example, using the parameter △E (color difference) that can be calculated from the CIELAB color space, in this embodiment, the range where △E ≤ 2.0 can be made the same color. The same-color layer 35 can have the same surface roughness as the light-emitting layer 33 when the vehicle light fixture 100 is viewed from the front. In this case, the invisible effect can be further enhanced. Specifically, the surface roughness can be made the same when the error in the ratio of the surface roughness Ra (arithmetic mean roughness) and Rz (maximum height) of the same-color layer 35 and the light-emitting layer 33 is within ±10 percent. The same-color layer 35 is arranged in a region of the second surface 34b of the substrate 34 that is different from the region where the light-emitting layer 33 is provided. In the example shown in Figures 3 and 4, the same-color layer 35 is arranged over the entire periphery of the light-emitting layer 33.

[0024] When forming this configuration, for example, the same-color layer 35 can be formed by first forming a layer that will be the same color layer 35 over the entire second surface 34b of the substrate 34, and then etching to create space for the light-emitting layer 33. Alternatively, a film with a space for the light-emitting layer 33 may be used as the same-color layer 35. The configuration can then be formed by placing the light-emitting layer 33 in the space of the same-color layer 35 using spray coating, screen printing, pad printing, etc. Furthermore, etching of the substrate 34 may be performed as needed when forming the same-color layer 35 and the light-emitting layer 33. Also, the space between the light-emitting layer 33 and the same-color layer 35 can be formed without gaps. Specifically, recesses can be created in the substrate 34 by etching, etc., and a solvent containing a fluorescent agent for forming the light-emitting layer 33 can be poured into these recesses to fill the space between the light-emitting layer 33 and the same-color layer 35 without gaps.

[0025] Furthermore, the light-emitting portion 31 and the support portion 32 may be formed flush on their front sides. Specifically, the emission surface 33a of the light-emitting layer 33 and the front surface 35a of the same-color layer 35 may be formed flush (the dashed line in Figure 3). With this configuration, no step is formed at the boundary between the light-emitting layer 33 and the same-color layer 35, making the boundary less visible when viewed from the front.

[0026] The operation of the vehicle lighting device 100 configured as described above will now be explained. By turning on the excitation light source 10, excitation light L (see Figure 2) is emitted from the excitation light source 10 and incident on the optical member 20. The excitation light L incident on the optical member 20 is emitted by the optical member 20 and irradiates the substrate 34. Of the excitation light L that irradiates the substrate 34, a portion of the excitation light L passes through the substrate 34 and irradiates the light-emitting layer 33. When the light-emitting layer 33 is irradiated with excitation light L, the light-emitting layer 33 is excited and emits generated light L1. The generated light L1 generated in the light-emitting layer 33 is emitted backward (towards the front).

[0027] Furthermore, when the excitation light source 10 is turned off, the emission layer 33 is not irradiated with excitation light L, and the emission layer 33 is in a non-emitting state. When the vehicle light fixture 100 is viewed from the front in the non-emitting state, the light-emitting part 31 (emission layer 33) and the support part 32 (same-color layer 35) are visible, as shown in Figure 4. In this embodiment, since the non-emitting emission layer 33 and the same-color layer 35 are formed in the same color, the boundary between the emission layer 33 and the same-color layer 35 becomes difficult to see.

[0028] Figure 5 is a schematic diagram showing another example of the light conversion unit. As shown in Figure 5, the light conversion unit 30A has a light-emitting unit 31A and a support unit 32A. The light-emitting unit 31A has a light-emitting layer 33A. The light-emitting layer 33A has the same configuration as the light-emitting layer 33 described above. The support unit 32A has a light-shielding layer 36 below the same-color layer 35A in a region of the second surface 34b of the substrate 34 that is different from the region where the light-emitting layer 33A is provided. The light-shielding layer 36 shields the generated light emitted from the light-emitting layer 33A. By providing the light-shielding layer 36 below the same-color layer 35A, the generated light emitted from the light-emitting layer 33A that diffuses in the left-right and up-down directions can be shielded by the light-shielding layer 36. Therefore, it is possible to suppress the generated light emitted from the light-emitting layer 33A from being emitted to the front side from the same-color layer 35A. This makes it possible to clearly distinguish between the light-emitting and non-light-emitting regions when viewed from the front side while the light-emitting layer 33A is emitting light.

[0029] Figure 6 is a schematic diagram showing another example of the light conversion unit. As shown in Figure 6, the light conversion unit 30B has a light-emitting unit 31B and a support unit 32B. The light-emitting unit 31B has a light-emitting layer 33B. In the example shown in Figure 6, mixed light of generated light emitted from the light-emitting layer 33B and excitation light emitted from the excitation light source 10 is emitted to the front. For example, if the excitation light is blue light and the generated light is yellow light, the mixed light will be white light. In this case, the light-emitting layer 33B can be made of, for example, YAG (Yttrium Aluminum Garnet). Note that the excitation light and generated light are not limited to blue and yellow, respectively, and may be other colors. In this case, other materials may be used for the excitation light source 10 and the light-emitting layer 33B. The light-emitting unit 31B also has a color-mixing layer 37. The color-mixing layer 37 is a layer that has a mixed color, which is the mixed color of the color of the excitation light and the color of the generated light, i.e., the color of the mixed light. The color mixing layer 37 is positioned on the front side (upper layer, rear in Figure 6) of the light-emitting layer 33. In other words, the light-emitting section 31B has a structure in which the light-emitting layer 33 and the color mixing layer 37 are stacked. When the light-emitting section 31B is viewed from the front side in a non-light-emitting state, the color of the light-emitting section 31B is the color of the color mixing layer 37 (mixed color).

[0030] The support portion 32B has a light-shielding layer 36 and a same-color layer 38. The light-shielding layer 36 is provided in a region of the second surface 34b of the substrate 34 that is different from the region where the light-emitting layer 33B is provided. The light-shielding layer 36 blocks the generated light emitted from the light-emitting layer 33B. The same-color layer 38 is the same color as the light-emitting portion 31B in its non-emitting state and is a mixed color. The same-color layer 38 is positioned on the front side (upper layer, rear in Figure 6) of the light-shielding layer 36. In other words, the support portion 32B has a configuration in which the light-shielding layer 36 and the same-color layer 38 are laminated on the substrate 34.

[0031] When the mixed color is white, materials such as TiO2 are used for the mixed color layer 37 and the same-color layer 38. The mixed color layer 37 needs to transmit light emitted by the light-emitting layer 33. On the other hand, the same-color layer 38 needs to prevent the color of the underlying light-shielding layer 36 from being visible when viewed from the front. For this reason, the light transmittance of the mixed color layer 37 is formed to be higher than that of the same-color layer 38. The light transmittance of the mixed color layer 37 and the same-color layer 38 can be adjusted by adjusting the layer thickness of the mixed color layer 37 and the same-color layer 38 and the concentration of the material such as TiO2 within the layers. The same-color layer 38 may be formed as the same layer as the mixed color layer 37. That is, a single layer of the mixed color may be formed on the upper side of the light-emitting layer 33B and the light-shielding layer 36.

[0032] Figure 7 is a schematic diagram showing another example of the light conversion unit. As shown in Figure 7, the light conversion unit 30C has a light-emitting unit 31C and a support unit 32C. The light-emitting unit 31C has a light-emitting layer 33C. The support unit 32C has a same-color layer 39 over the entire second surface 34b of the substrate 34. The same-color layer 39 is formed to be the same color as the light-emitting layer 33C in its non-light-emitting state. The light-emitting layer 33C is placed on the front surface 39a of the same-color layer 39. In the example shown in Figure 7, the same-color layer 39 may be opaque. In this case, by placing an excitation light source on the front side (rear) of the light-emitting layer 33C and irradiating excitation light from the excitation light source toward the back side (front), generated light can be produced in the light-emitting layer 33C.

[0033] Figure 8 schematically shows another example of a vehicle lighting fixture. As shown in Figure 8, the vehicle lighting fixture 100D can be formed such that at least one of the surfaces 51D of the housing 50, the front surface 12D of the light source substrate 11, and the front surface 61D of the inner panel 60 is the same color as the non-emitting light-emitting portion 31 (light-emitting layer 33) when viewed from the front.

[0034] As described above, the vehicle light fixture 100 according to this embodiment comprises an excitation light source 10 that emits excitation light, light-emitting sections 31, 31A, 31B, 31C having light-emitting layers 33, 33A, 33B, 33C that generate and emit generated light upon irradiation with excitation light, and support sections 32, 32A, 32B, 32C having a substrate 34 arranged on the back side of the light-emitting layers 33, 33A, 33B, 33C to support the light-emitting layers 33, 33A, 33B, 33C, and the support sections 32, 32A, 32B, 32C are formed to be the same color as the light-emitting sections 31, 31A, 31B, 31C when viewed from the front side.

[0035] With this configuration, when viewed from the front, the support parts 32, 32A, 32B, and 32C are formed to be the same color as the non-illuminating light-emitting parts 31, 31A, 31B, and 31C, thus suppressing the visibility of the design of the light-emitting parts 31, 31A, 31B, and 31C from the outside when they are not lit.

[0036] In the vehicle lighting device 100 according to this embodiment, the support portion 32 has layers 35, 35A, 38, and 39 of the same color as the light-emitting portions 31, 31A, 31B, and 31C in the non-light-emitting state formed on the front side of the substrate 34.

[0037] With this configuration, by providing same-color layers 35, 35A, 38, and 39, it is possible to appropriately realize a configuration in which, when viewed from the front, the support parts 32, 32A, 32B, and 32C are the same color as the non-emitting light-emitting parts 31, 31A, 31B, and 31C.

[0038] In the vehicle lighting device 100 according to this embodiment, the support portion 32 has a light-shielding layer 36 below the same-color layers 35A and 38 in a region on the front side of the substrate 34 that is different from the region where the light-emitting portions 31A and 31B are provided.

[0039] With this configuration, a light-shielding layer 36 is provided below the same-color layers 35A and 38, thereby blocking the generated light emitted from the light-emitting layers 33A and 33B that diffuses in the left-right and up-down directions. As a result, it is possible to suppress the emission of generated light from the light-emitting layers 33A and 33B from the same-color layers 35A and 38 towards the front. This makes it possible to clearly distinguish between the light-emitting and non-light-emitting regions when viewed from the front while the light-emitting layers 33A and 33B are emitting light.

[0040] In the vehicle lighting device 100 according to this embodiment, the light-emitting portion 31 and the support portion 32 are formed to be flush with each other on their front sides.

[0041] With this configuration, no step is formed at the boundary between the light-emitting part 31 and the support part 32, making it difficult to see the boundary when viewed from the front.

[0042] The vehicle lamp 100 according to this embodiment further comprises a housing 50 that forms a lamp chamber, a light source substrate 11 that supports an excitation light source 10, and an inner panel 60 disposed inside the lamp chamber, wherein at least one of the housing 50, the light source substrate 11, and the inner panel 60 has surfaces 51D, 12D, and 61D that are the same color as the light-emitting part 31 when it is not emitting light.

[0043] With this configuration, by making at least one surface 51D, 12D, 61D of the housing 50, light source substrate 11, and inner panel 60 the same color as the light-emitting part 31 when it is not lit, it is possible to more reliably suppress the visibility of the design of the light-emitting part 31 from the outside when it is not lit.

[0044] In the vehicle light fixture 100 according to this embodiment, the light-emitting section 31 has a color-mixing layer 37 on the front side of the light-emitting layer 33B, which is a mixed color of the color of the excitation light and the color of the generated light, and the color of the light-emitting section 31 in the non-emitting state is the mixed color of the color-mixing layer 37.

[0045] With this configuration, when the color of the light-emitting layer 33B differs between the non-light-emitting state and the light-emitting state, the color mixing layer 37 can be placed on the front side of the light-emitting layer 33B to match the color of the light-emitting section 31B in the non-light-emitting state to the color of the light-emitting layer 33B when it is emitting light.

[0046] In the vehicle lighting device 100 according to this embodiment, the support portion 32 has a same-color layer 38 of the same color as the light-emitting layer 33B, which is the light-emitting portion 31B in a non-light-emitting state, formed on the front side of the substrate 34, and the light transmittance of the mixed-color layer 37 is formed to be higher than the light transmittance of the same-color layer 38.

[0047] With this configuration, the light emitted by the light-emitting layer 33B can be transmitted through the color-mixing layer 37, and the color of the light-shielding layer 36, which is the base layer, can be made invisible from the front side compared to the same-color layer 38.

[0048] The technical scope of the present invention is not limited to the embodiments described above, and modifications can be made as appropriate without departing from the spirit of the invention. For example, in the embodiments described above, a configuration in which one set each of support parts 32, 32A, 32B, 32C and light-emitting parts 31, 31A, 31B, 31C is provided was given as an example, but the invention is not limited to this configuration. For example, a configuration in which multiple sets of combinations of support parts 32, 32A, 32B, 32C and light-emitting parts 31, 31A, 31B, 31C may be provided. In this case, multiple sets of support parts 32, 32A, 32B, 32C and light-emitting parts 31, 31A, 31B, 31C may be arranged in a front-to-back direction.

[0049] Furthermore, although the above embodiment was described using a configuration in which the vehicle lights 100 and 100D are provided at the rear of the vehicle body 2 as an example, the invention is not limited to this configuration. The vehicle lights 100 and 100D may also be provided at the front of the vehicle body 2. In this case, the vehicle lights 100 and 100D may be provided as headlamps (vehicle headlights), clearance lamps, daytime running lamps, front turn signal lamps, etc. [Explanation of Symbols]
