[0050] Hereinafter, based on the accompanying drawings, eight examples of embodiments (examples) of the vehicle lamp of the present invention will be described in detail. In this specification, front, rear, top, bottom, left, and right refer to the front, rear, top, bottom, left, and right sides of the vehicle lamp of the present invention mounted on the rear of a vehicle. Furthermore, in the accompanying drawings, since they are simplified diagrams, only the main components are shown, and the illustrations of components other than the main components are omitted. Also, some of the shaded lines on the components are omitted.

[0051] (Explanation of the structure of Implementation Method 1)

[0052] Figures 1 to 4 Embodiment 1 of the vehicle lamp of the present invention is shown. Hereinafter, the structure of the vehicle lamp of Embodiment 1 will be described.

[0053] (Explanation of Vehicle V)

[0054] Figures 1 to 4 In this diagram, the symbol V represents a vehicle. The vehicle V utilizes body panels P and window glass G to form the passenger compartment R. For example, an opening O is provided in the body panel P at the rear of the vehicle V. A window glass G is inserted into the opening O, thus forming the passenger compartment R. A person H rides inside the passenger compartment R.

[0055] Rear combination lights are installed on the left and right sides of the rear of vehicle V. Front combination lights (not shown) are also installed on the left and right sides of the front of vehicle V. Additionally, other vehicle lights (not shown) are installed on the exterior and interior (inside the passenger compartment R) of vehicle V.

[0056] (Instructions for vehicle lighting fixture 1)

[0057] Figures 1 to 4 In this embodiment, symbol 1 refers to the vehicle lamp 1. In this example, the vehicle lamp 1 is a taillight constituting the rear combination lamp. In addition to the taillight, the vehicle lamp 1 can also be a brake light or a rear brake light. The vehicle lamp 1 is installed on the left and right sides of the rear of the vehicle V.

[0058] The following description will focus on the vehicle light fixture 1 installed on the left side of the vehicle. Furthermore, the vehicle light fixture installed on the right side of the vehicle is approximately symmetrical in structure to the vehicle light fixture 1 installed on the left side. Therefore, the description of the vehicle light fixture installed on the right side of the vehicle will be omitted.

[0059] The vehicle lamp 1 includes a lamp housing 10, a lamp lens 11, a light source 2, a reflector 3, and a shielding component (in this example, a vehicle body panel P).

[0060] The lamp housing 10 is made of, for example, a non-transparent component (resin component, etc.).

[0061] The lamp lens 11 is, for example, a transparent outer cover or an outer lens. In this example, the lamp lens 11 is made of a light-transmitting resin component such as PC or PMMA. The raw material for the lamp lens 11 is preferably a material with high transmittance in the visible light region. In this example, the lamp lens 11 is red. However, if the light L1 from the light source 2 is red light, the lamp lens 11 may also be colorless and transparent.

[0062] The lamp lens 11 is mounted on the lamp housing 10. Thus, the lamp housing 10 and the lamp lens 11 form the lamp chamber 12.

[0063] (Explanation of Light Source Section 2)

[0064] The light source unit 2 is disposed within the lamp housing 12. The light source unit 2 is mounted to at least one of the lamp housing 10 or the lamp lens 11 via a mounting member (not shown). The light source unit 2 is mounted to the inner side of the roof portion of the vehicle body panel P via the lamp housing 10. Furthermore, the lamp housing 10 is mounted to the vehicle body panel P directly or via a mounting member (not shown).

[0065] Furthermore, the light source 2, along with the lamp housing 10 and the lamp lens 11, is covered by part of the roof portion of the vehicle body panel P, which serves as a shielding component. Therefore, when viewed from the rear of the vehicle V, as... Figure 1 and Figure 2 As shown by the dotted line, the light source 2, lamp housing 10, and lamp lens 11 are obscured by the body panel P and cannot be seen.

[0066] That is, the vehicle lamp 1 includes a portion of the roof panel P as a shielding component, which shields the light source 2 from a line of sight (L4) in the opposite direction to the light emission direction (emitted light L3) of the reflector 3. As a result, the light source 2 is not visible because it is shielded from the light emission direction (L4) of the reflector 3 by the portion of the roof panel P as a shielding component. In other words, the light source 2 is positioned in a location where it is physically invisible when not illuminated. Furthermore, as... Figure 3 As shown by the double-dotted line, by installing a decorative ceiling panel P1 on the ceiling inside the vehicle compartment R, the light source unit 2 is not physically visible from inside the vehicle compartment R.

[0067] The light source unit 2 includes a light source 20 and an optical substrate 21. In this example, the light source 20 is an LED that emits light L2. The light source 20 is mounted on the lamp housing 10 via a circuit board 22 and the like. In this example, the light L2 from the light source 20 is red light, but if the lamp lens 11 is a red lens, it could also be white light.

[0068] The number of light sources 20 can be one or more. When there are multiple light sources 20, the lighting and extinguishing of each light source 20 can be controlled separately.

[0069] The optical substrate 21 is supported on the circuit board 22 by a support member 23, etc. The optical substrate 21 is disposed between the light source 20 and the lamp lens 11. In this example, the optical substrate 21 is made of a light-transmitting resin component such as PC or PMMA, or glass. The raw material for the optical substrate 21 is preferably a material with high transmittance in the visible light region. The optical substrate 21 is optically designed to meet the light distribution requirements of the taillight function.

[0070] A design section 24 is provided on the optical substrate 21. The design section 24 designs the pattern of the light L3 (hereinafter referred to as "emitted light L3") emitted from outside the lamp chamber 12 and to the rear side of the vehicle V outside the vehicle chamber R. That is, the design section 24 designs the light L2 from the light source 20 into a pattern that functions as a taillight, and emits it towards the reflector 3 as light L1 from the light source 2.

[0071] In this example, design section 24 is composed of a diffuse surface. Therefore, as... Figure 2 As shown in the additional grid pattern section, the emitted light L3 designed in design section 24 has a quadrilateral emitting surface. However, the emitting surface pattern of the emitted light L3 can also be a pattern of a emitting surface other than the quadrilateral shape used in this example.

[0072] Furthermore, since the design section 24 needs to take the haze rate into account according to the design, there are no special requirements for the surface roughness of the design section 24.

[0073] Furthermore, the light source unit 2 can also be the light source units 2C, 2D, and 2F of the vehicle lamps 1C, 1D, and 1F described in embodiments 4, 5, and 7 below. In this case, the lamp lens 11 can also be a lamp lens made of a colorless light-transmitting component.

[0074] Furthermore, the light source 2E of the vehicle lamp 1E described in Embodiment 6 can also be used as the light source 2. In this case, it is preferable to use a lamp lens (a red lamp lens) that is composed of a light-transmitting component that absorbs the color of the excitation light L6 of the light source 2E as the lamp lens 11.

[0075] (Explanation of reflector 3)

[0076] The reflector 3 and the lamp lens 11 are integrally formed. Alternatively, the reflector 3 and the lamp lens 11 can be separate structures. The reflector 3 is disposed outside the lamp chamber 12 facing the lamp lens 11. The reflector 3 is disposed below the light source 2. That is, the light source 2 and the reflector 3 are disposed vertically.

[0077] The reflector 3 reflects the light L1 emitted from the lamp lens 11 to the outside of the lamp chamber 12 from the light source 2, and emits the reflected light L3 as the outgoing light L3 again in a predetermined direction (the direction of light distribution that satisfies the taillight function) to the outside of the lamp chamber 12 and to the rear side of the vehicle V outside the vehicle chamber R.

[0078] Furthermore, the reflector 3 reflects light L4 (hereinafter referred to as "external light L4") from the rear side of the vehicle V, which originates from outside the lamp chamber 12 and outside the vehicle compartment R. (See reference...) Figure 3 The solid arrow L4 in the middle extends out of the lamp compartment 12 and into the front of the vehicle V inside the vehicle compartment R.

[0079] In this example, similar to the lamp lens 11, the reflective part 3 is made of a light-transmitting resin component such as PC or PMMA, or glass. The reflective part 3 is made of a transparent component with a refractive index greater than 1, at least in the visible light region. Furthermore, the reflective part 3 can be colorless or colored.

[0080] In this example, the reflector 3 is part of the window glass G, which forms the rear of the vehicle compartment R as a transparent wall component. That is, the reflector 3 is a portion of the window glass G. The reflector 3 is composed of a single sheet component. The reflector 3, together with the window glass G, is positioned at the opening O of the body panel P at the rear of the vehicle V.

[0081] Similar to the optical substrate 21, the reflector 3 is optically designed to provide light distribution for the taillight function. Furthermore, light distribution control can be performed on either the reflector 3 or the optical substrate 21. Additionally, light distribution control can also be performed on the lamp lens 11.

[0082] Furthermore, in this example, the reflective part 3 is a transparent wall component forming the vehicle compartment R and constitutes part of the window glass G. However, the reflective part 3 can also be a transparent wall component other than the window glass G. That is, it is also possible that a part of the body panel P of any part of the vehicle V is formed by a transparent wall component, and the reflective part 3 constitutes part of that transparent wall component. In this case, the inner side of the reflective part 3 may not be the vehicle compartment R. For example, it could be the luggage compartment, etc.

[0083] (Explanation of the function of Implementation Method 1)

[0084] The vehicle lamp 1 of this embodiment 1 is constructed according to the above structure, and its function will be explained below.

[0085] When the light source 20 of the light source unit 2 is not lit, it is in a state of... Figure 1 and Figure 3 The state shown indicates that the light distribution does not illuminate the taillights. In this state, the reflector 3 is part of the window glass G and is composed of a transparent component. Therefore, as... Figure 3As shown by the solid arrow in the image, line L5 indicates that a person H inside the vehicle compartment R can see the scenery outside the vehicle compartment R from eye point IP1 through the reflector 3 and the window glass G.

[0086] On the other hand, such as Figure 3 As shown by the solid arrow, external light L4 enters the vehicle compartment R from the rear side of the vehicle V outside the compartment R through the reflector 3. At this time, the external light L4 is not reflected towards the light source 2 in the reflector 3. Therefore, as... Figure 3 As shown by the solid arrow L4, when the interior of the vehicle R is viewed from the rear viewpoint IP2 outside the vehicle R via the reflector 3 and the window glass G, it appears that neither the light source 2 nor the reflector 3 is visible. In particular, since the light source 2 is partially covered by the roof portion of the body panel P, which serves as a shielding component, it is positioned in a physically invisible location. Therefore, when viewed from inside or outside the body panel P when not illuminated, the light source 2 is not visible. Furthermore, Figure 3 In the diagram, the symbol “L4” for external light and the symbol “L4” for the line of sight from eye point IP2 outside the cabin R use the same symbol.

[0087] Light source 20 of light source section 2 is turned on. Thus, as... Figure 2 and Figure 4 As shown, light (red light) L2 emitted from light source 20 passes through optical substrate 21 and design section 24. At this time, the optical substrate 21 and design section 24 perform light distribution control and design on light L2.

[0088] The light L1, which is controlled and designed by the light source unit 2, is emitted from the lamp lens 11 as light (red light) L1 and is emitted from the upper side of the vehicle V downwards towards the outside of the lamp housing 12. The light L1 emitted outside the lamp housing 12 is also reflected in the reflector 3 by the light distribution control to a predetermined direction. This reflected light L3 is emitted again as outgoing light L3 from the front side of the vehicle V towards the rear side towards the outside of the lamp housing 12 and towards the outside of the vehicle compartment R. That is, the light distribution is used to illuminate the rear side of the vehicle V for the purpose of taillights.

[0089] In this way, the optical axis of the emitted light L1 (from the upper side of the vehicle V to the lower side) emitted from the lamp lens 11 of the light source section 2 located on the upper side, and the optical axis of the emitted light L3 (from the front side of the vehicle V to the rear side) emitted from the reflector section 3 located on the lower side relative to the light source section 2, change in the medium of the reflector section 3. Moreover, the light L1, which is light-distributed and designed, is also reflected in the reflector section 3 in a predetermined direction by light distribution control.

[0090] The emitted light L3 enters the eye point IP2 of a person located at the rear of the vehicle V, outside the passenger compartment R. Therefore, the luminous surface of the taillight function ( Figure 2 The portion of the window glass G containing the checkered pattern is illuminated and visible.

[0091] Furthermore, even when light source section 2 is lit, it is as follows: Figure 4 As shown by the solid arrow in the image, line L5 indicates that a person H inside the vehicle compartment R can see the scenery outside the vehicle compartment R from eye point IP1 through the reflector 3 and the window glass G.

[0092] (Explanation of the effects of Implementation Method 1)

[0093] The vehicle lamp 1 of this embodiment 1 has the structure and function described above, and its effects will be explained below.

[0094] In the vehicle lamp 1 of this embodiment 1, the light source 2 is disposed at a position offset upwards from the emission direction (horizontal direction) of the emitted light L3 from the reflector 3. That is, in the vehicle lamp 1 of this embodiment 1, the light source 2 is disposed at a position that is not visible from a line of sight (L4) in the direction opposite to the emission direction of the emitted light L3 emitted from the reflector 3. As a result, in the vehicle lamp 1 of this embodiment 1, when the light source 2 is not lit, when viewed from a line of sight (L4) in the direction opposite to the emission direction of the emitted light L3 from the reflector 3, the reflector 3 of the transparent component can be seen, resulting in a transparent appearance.

[0095] Furthermore, in the vehicle lamp 1 of this embodiment 1, when the light source 2 is lit, the light from the light source 2 is reflected in the reflector 3 and emitted in a predetermined direction. As a result, in the vehicle lamp 1 of this embodiment 1, when the light source 2 is lit, when viewed from a line of sight (L4) in the opposite direction to the emission direction of the emitted light L3 from the reflector 3, the light (emitted light L3) can be seen from the transparent portion of the reflector 3 of the transparent component.

[0096] In the vehicle lamp 1 of this embodiment 1, since the reflector 3 is made of a transparent component with a refractive index greater than 1 at least in the visible light region, the light L1 from the light source 2 can be reliably reflected by the reflector 3 and emitted in a predetermined direction. As a result, the vehicle lamp 1 of this embodiment 1 obtains the predetermined light distribution for the lamp function (taillight function).

[0097] The vehicle lamp 1 of this embodiment 1 includes a line of sight (L4) from the opposite direction to the emission direction of the emitted light L3 emitted from the self-reflecting part 3, which blocks a portion of the roof portion of the vehicle body panel P, which serves as a shielding member, of the light source part 2. As a result, in the vehicle lamp 1 of this embodiment 1, since the light source part 2 is shielded (covered) by a portion of the roof portion of the vehicle body panel P, it is not visible when the light source part 2 is not lit. Furthermore, in the vehicle lamp 1 of this embodiment 1, since the reflecting part 3 reflects the light L1 from the light source part 2 and causes it to be emitted in a predetermined direction, the reflecting part 3 of the transparent member emits light and becomes visible when the lamp is lit. Thus, in the vehicle lamp 1 of this embodiment 1, the light source part 2 is not visible when it is not lit, and the light L1 from the light source part 2 is visible when it is lit. That is, in the vehicle lamp 1 of this embodiment 1, when the light source part 2 is not lit, a transparent appearance can be reliably obtained, and when the light source part 2 is lit, light (emitted light L3) can be reliably seen from the transparent part.

[0098] In the vehicle lamp 1 of this embodiment 1, the light source 2 is disposed inside the lamp chamber 12 formed by the lamp housing 10 and the lamp lens 11, and the reflector 3 is disposed outside the lamp chamber 12 facing the lamp lens 11. As a result, in the vehicle lamp 1 of this embodiment 1, when the light source 2 is not lit, light from outside the lamp chamber 12, i.e., external light L4, passes through the reflector 3, so the reflector 3 outside the lamp chamber 12 remains transparent and cannot be seen, and the light source 2 inside the lamp chamber 12 is also physically invisible.

[0099] Thus, the vehicle lamp 1 of this embodiment 1 becomes a vehicle lamp that functions as an invisible lamp when the light source 2 is not lit. Furthermore, the vehicle lamp 1 of this embodiment 1 is, in appearance, a vehicle lamp without a lamp lens that does not use a lamp lens.

[0100] The vehicle lamp 1 of this embodiment 1 utilizes a reflector 3 to reflect light L1 emitted from the lamp lens 11 and directed towards the lamp chamber 12 from the light source 2, causing the reflected light L3 to be emitted again as outgoing light L3 towards the lamp chamber 12. As a result, when the light source 2 is lit, the reflector 3 outside the lamp chamber 12 of the vehicle lamp 1 of this embodiment 1 emits light and becomes visible.

[0101] Furthermore, in the vehicle lamp 1 of this embodiment 1, the light source section 2 and the reflector section 3 are arranged vertically, and the emission direction of the emitted light L1 (from the upper side of the vehicle V to the lower side) emitted from the lamp lens 11 of the light source section 2 and the emission direction of the emitted light L3 (from the front side of the vehicle V to the rear side) emitted from the reflector section 3 are varied in the reflector section 3. As a result, the vehicle lamp 1 of this embodiment 1 is a vehicle lamp whose depth dimension is equal to the thickness of the reflector section 3, which is smaller than the depth dimension from the lamp housing to the lamp lens of conventional vehicle lamps. That is, the vehicle lamp 1 of this embodiment 1 is a compact vehicle lamp.

[0102] In the vehicle lamp 1 of this embodiment 1, the reflector 3 is composed of a portion of the window glass G that forms the transparent wall component of the vehicle cabin R. As a result, in the vehicle lamp 1 of this embodiment 1, when the light source 2 is not lit, a person H inside the vehicle cabin R can see the scenery outside the vehicle cabin R through the reflector 3 and the window glass G. On the other hand, when the vehicle cabin R is observed from the rear of the vehicle V outside the vehicle cabin R through the reflector 3 and the window glass G, it appears as if the light source 2 and the reflector 3 are not present.

[0103] In the vehicle lamp 1 of this embodiment 1, since the reflector 3 is composed of a single plate component, the reflector 3 can be manufactured cheaply and is applicable to a single window glass G.

[0104] In the vehicle lamp 1 of this embodiment 1, since the light source unit 2 has a light source 20 and an optical substrate 21, the light distribution control of the emitted light L3 emitted from the reflector 3 can obtain the light distribution of the predetermined lamp function (taillight function in this example).

[0105] In the vehicle lamp 1 of this embodiment 1, since the optical substrate 21 is provided with a design portion 24 for designing the pattern of the emitted light L3 emitted towards the lamp chamber 12, it is possible to obtain light distribution with a predetermined lamp function (taillight function in this example) and light distribution with an arbitrary pattern. Moreover, since the design portion 24 is composed of a diffuse surface, it is possible to obtain surface-emitting light distribution.

[0106] In the vehicle lamp 1 of this embodiment 1, when there are multiple light sources 20 in the light source section 2, the lighting and extinguishing of each of the multiple light sources 20 can be controlled individually, thus achieving dynamic light-emitting surface and light distribution. Furthermore, the reflector section 3 becomes a component with display function.

[0107] (Explanation of the structure, function, and effects of Implementation Method 2)

[0108] Figure 5Embodiment 2 of the vehicle lamp of the present invention is shown. Hereinafter, the structure, function, and effects of the vehicle lamp 1A of Embodiment 2 will be described. In the accompanying drawings, [the following text is incomplete and likely refers to a different embodiment of the invention]. Figures 1-4 The same symbol represents the same item.

[0109] The vehicle lamp 1A of this embodiment 2 is a variation of the vehicle lamp 1 of embodiment 1 described above. Furthermore, the light source section 2A of the vehicle lamp 1A of this embodiment 2 has the same structure as the light source section 2 of the vehicle lamp 1 of embodiment 1 described above.

[0110] The reflector 3 of the vehicle lamp 1 in Embodiment 1 described above is composed of a single plate component. In contrast, the reflector 3A of the vehicle lamp 1A in Embodiment 2 is composed of multiple plate components, specifically three plate components in this example. Furthermore, the reflector 3A can be composed of two or more plate components.

[0111] A light-transmitting portion 30A is provided between the three reflective portions 3A. The light-transmitting portion 30A can be made of a transparent component or it can be a space. In the case of a space, the three reflective portions 3A are supported by supporting components such as line components and rod components.

[0112] In the vehicle lamp 1A of this embodiment 2, since the reflector 3A is composed of three plate components, a portion of the light L1 from the light source 2A is reflected by the first reflector 3A as emitted light L3, and the remaining portion of the light L1 from the light source 2A passes through the first reflector 3A.

[0113] A portion of the light L1 from the light source 2A that has passed through the first reflector 3A is reflected by the second reflector 3A as emitted light L3, while the remainder passes through the second reflector 3A. Furthermore, a portion of the light L1 from the light source 2A that has passed through the second reflector 3A is reflected by the third reflector 3A as emitted light L3.

[0114] The vehicle lamp 1A of this embodiment 2 has the structure and function described above, and therefore can achieve the same effect as the vehicle lamp 1 of embodiment 1 described above. In particular, in the vehicle lamp 1A of this embodiment 2, since the reflector 3A is composed of a three-plate component, a novel light distribution function can be obtained.

[0115] (Explanation of the structure, function, and effects of Implementation Method 3)

[0116] Figure 6 Embodiment 3 of the vehicle lamp of the present invention is shown. Hereinafter, the structure, function, and effects of the vehicle lamp 1B of Embodiment 3 will be described. In the accompanying drawings, [the following text is incomplete and likely refers to a different embodiment of the invention]. Figures 1-5 The same symbol represents the same item.

[0117] The vehicle lamp 1B of this embodiment 3 is a variation of the vehicle lamp 1 of embodiment 1 described above. Furthermore, the light source part 2B and the reflector part 3B of the vehicle lamp 1B of this embodiment 3 are constructed with the same structure as the light source part 2 and the reflector part 3 of the vehicle lamp 1 of embodiment 1 described above.

[0118] The vehicle lamp 1 of this embodiment 3 includes a patterned component 4. The pattern is provided on at least one of the front (the rear side of the vehicle V) or the back (the front side of the vehicle V) of the patterned component 4.

[0119] Pattern component 4 is positioned relative to reflective portion 3B on the side that reflects light L1 from light source portion 2B in the direction of reflective portion 3B. Figure 4 and Figure 5 The side of the emitted light L3 that is emitted is the rear side of the vehicle V (hereinafter referred to as the "front side of the reflector 3"). The opposite side is the front side of the vehicle V (hereinafter referred to as the "rear side of the reflector 3").

[0120] In this example, the pattern component 4 is arranged throughout the window glass G and the reflective part 3. Alternatively, the pattern component 4 can also be arranged correspondingly to a part of the window glass G and the reflective part 3.

[0121] The front side of the patterned component 4 faces the reflective part 3B. Furthermore, the back side of the patterned component 4 faces the opposite side of the vehicle compartment R, relative to the reflective part 3B.

[0122] The vehicle lamp 1B of this embodiment 3 is constructed with the above-described structure, therefore, as Figure 6 As shown by the solid arrow L4, when the interior of the vehicle compartment R is viewed from the rear of the vehicle V through the reflector 3B, the pattern on the front of the pattern member 4 can be seen. On the other hand, although not shown, when the rear of the vehicle V is viewed from inside the vehicle compartment R, the pattern on the back of the pattern member 4 can be seen.

[0123] The vehicle lamp 1B of this embodiment 3 has the structure and function described above, and therefore can achieve the same effect as the vehicle lamps 1 and 1A of embodiments 1 and 2 described above.

[0124] In particular, in the vehicle lamp 1B of this embodiment 3, since a pattern member 4 with a pattern is arranged on the back side of the reflector 3B, when the back side of the reflector 3 is viewed from the front side, the pattern on the front of the pattern member 4 can be seen, and the back side of the pattern member 4 can be covered and hidden.

[0125] (Explanation of the structure of Implementation Method 4)

[0126] Figure 7 and Figure 8Embodiment 4 of the vehicle lamp of the present invention is shown. Hereinafter, the structure of the vehicle lamp 1C of this embodiment 4 will be described. In the accompanying drawings, [the following text is incomplete and likely refers to a different document or model]. Figures 1-6 The same symbol represents the same item.

[0127] (Instructions for vehicle lighting fixtures 1C)

[0128] In the vehicle lamps 1-1B of embodiments 1-3 described above, the light source portions 2-2B are disposed inside the lamp chamber 12, and the reflector portions 3-3B are disposed outside the lamp chamber 12. In contrast, in the vehicle lamp 1C of this embodiment 4, the reflector portion 3C is disposed inside the lamp chamber 12. Furthermore, the vehicle lamp 1C of this embodiment 4 includes one or more excitation light sources 200.

[0129] The lamp chamber 102 is formed by a lamp housing 100 and a lamp lens 101. The lamp housing 100 and lamp lens 101 of this embodiment 4 are made of articles that are substantially the same as the lamp housing 10 and lamp lens 11 of embodiments 1 to 3 described above.

[0130] The lamp housing 100 and the lamp lens 101 are mounted directly or via a mounting component (not shown) to the vehicle body panel P. The lamp lens 101 is disposed in the opening O of the vehicle body panel P.

[0131] On the side of the lamp housing 100 facing the lamp chamber 102, there is an external light absorption layer 40 that absorbs light L4 that enters the lamp chamber 102 from outside through the lamp lens 101. The external light absorption layer 40 is preferably made of a material with a high light absorption coefficient in the visible light region (visible light). In this example, pure black paint is used.

[0132] The vehicle lamp 1C of this embodiment 4 is disposed inside the body panel P of the vehicle V. The lamp lens 101 is disposed in the opening of the body panel P and protrudes to the outside of the body panel P. In this example, the lamp lens 101 is made of a colorless light-transmitting component.

[0133] In the vehicle lamp 1C of this embodiment 4, the lamp housing 100 forming the lamp chamber 102 has an upper opening. A light source 2C is disposed at the upper opening of the lamp housing 100. That is, the light source 2C is disposed outside the lamp chamber 102 and faces the lamp chamber 102. Alternatively, it may be as follows... Figure 7 The lamp housing 100 is configured as shown by the double-dotted line, and the light source unit 2C is arranged inside the lamp chamber 102.

[0134] (Explanation of Light Source Section 2C)

[0135] The light source unit 2C is mounted directly or via a mounting component (not shown) to the lamp housing 100 and the lamp lens 101. The light source unit 2C includes a light conversion component 201, a light-emitting layer 202, and an excitation light blocking component 203.

[0136] In this example, the excitation source 200 uses an LED, LD (semiconductor laser), or similar device to illuminate excitation lights L6 and L7. Excitation lights L6 and L7 are short-wavelength lights, such as blue, violet, or ultraviolet light. Furthermore, the symbol "L6" indicates excitation light incident onto the light-emitting layer 202, while the symbol "L7" indicates excitation light that does not pass through the light-emitting layer 202.

[0137] When there are multiple excitation light sources 200, they can be the same as the light source 20 of the vehicle lamps 1 to 1B in embodiments 1 to 3 described above, and the multiple excitation light sources 200 can be controlled to be lit and extinguished separately.

[0138] The light-emitting layer 202 is composed of organic light-emitting materials, inorganic light-emitting materials, etc. The light-emitting layer 202 uses excitation light L6 emitted from the excitation light source 200 to perform photoluminescence. In this example, it produces red light with a wavelength longer than that of the excitation light L6 and L7.

[0139] The light conversion component 201 is disposed between the excitation light source 200 and the reflector 3C. Similar to the optical substrate 21 of the vehicle lamps 1 to 1B in Embodiments 1 to 3 described above, the light conversion component 201 is made of a transparent support substrate.

[0140] A light-emitting layer 202 is formed on a portion of the light conversion component 201. Alternatively, the light-emitting layer 202 may be formed on the entire light conversion component 201.

[0141] The light conversion component 201 is a component that directs the photoluminescence generated in the light-emitting layer 202 as light L8 from the light source unit 2C into the reflector unit 3C. The light conversion component 201 is optically designed to meet the light distribution requirements of the taillight function.

[0142] In the light conversion component 201, or in this example, in the light-emitting layer 202, a design portion 202 (using the same symbol "202" as the symbol "202" for the light emitted from the lamp chamber 102) is provided. In this example, the design portion 202 is located in an area approximately equal to the light-emitting layer 202. That is, the design portion 202 is located as a part of the light conversion component 201. Alternatively, the design portion 202 may be located throughout the entire light conversion component 201. The design portion (light-emitting layer 202) is composed of a diffuse surface.

[0143] The excitation light blocking component 203 is disposed between the light conversion component 201 side and the reflector 3C and lamp lens 101 side. The excitation light blocking component 203 blocks the excitation light L7 (leakage excitation light L7) that has not passed through the light-emitting layer 202 of the light conversion component 201 in the excitation light L6 and L7.

[0144] The excitation light blocking component 203 is composed of a component that allows photoluminescence (red light L8) to pass through and absorbs excitation light L6 and L7. In this example, it is composed of a red transparent component.

[0145] (Explanation of reflector 3C)

[0146] The reflector 3C is mounted directly or via a mounting component (not shown) to the lamp housing 100 and the lamp lens 101. The reflector 3C is disposed within the lamp chamber 102 facing both the light source 2C and the lamp lens 101. The reflector 3C reflects the light L8 (photoluminescent red light) from the light source 2C, which then passes through the lamp lens 101 and is emitted out of the lamp chamber 102 in a predetermined direction.

[0147] Furthermore, the reflector 3C allows light (external light) L4 to pass through the lamp lens 101 from outside the lamp chamber 102 and into the lamp chamber 102.

[0148] In this example, the reflector 3C is composed of a single plate component. Alternatively, the reflector 3C may also be the same as the reflector 3A of the vehicle lamp 1A in Embodiment 2 described above, and be composed of multiple plate components.

[0149] (Explanation of the function of Implementation Method 4)

[0150] The vehicle lamp 1C of this embodiment 4 is constructed according to the above structure, and its function will be explained below.

[0151] When the excitation light source 200 is not lit, it is in Figure 7 The state shown indicates that the light distribution does not illuminate the taillights. At this time, as... Figure 7 As shown by the solid arrow, external light L4 enters the lamp housing 102 from the rear side of the vehicle V outside the lamp housing 102 through the lamp lens 101. Here, since the reflector 3C inside the lamp housing 102 is made of a transparent component, the external light L4 passes through the reflector 3C and is not reflected towards the light source 2C within the reflector 3C.

[0152] The result, such as Figure 7 As shown by the solid arrow L4, when the inside of the lamp chamber 102 is viewed through the lamp lens 101 from the eye point IP2 on the rear side of the vehicle V outside the lamp chamber 102, it appears that there is no light source part 2C and reflector part 3C.

[0153] Furthermore, the incoming light L4, after passing through the reflector 3C, is absorbed by the incoming light absorption layer 40 provided on the inner surface of the lamp housing 100. Therefore, there is no situation where the light source 2C or the like is visible from outside the lamp chamber 102 due to the incoming light L4 reflecting into the reflector 3C and passing through the lamp lens 101. That is, without the incoming light absorption layer 40, the incoming light L4 is reflected by the inner surface of the lamp housing 100 and enters the light source 2C or the like. Depending on the line of sight from the eyepoint IP2 outside the lamp chamber 102, sometimes the light source 2C or the like is reflected into the reflector 3C and can be seen from outside the lamp chamber 102 through the lamp lens 101. In contrast, by providing the incoming light absorption layer 40, the incoming light absorption layer 40 absorbs the incoming light L4, so there is no situation where the light source 2C or the like is visible from outside the lamp chamber 102 due to the incoming light L4 reflecting into the reflector 3C.

[0154] Turn on the excitation light source 200. In this way, as... Figure 8 As shown, a portion L6 of the excitation light (shorter wavelength blue light, violet light, ultraviolet light, etc.) L6 and L7 emitted from the excitation source 200 is directed into the light-emitting layer 202 (design part 202) of the light conversion component 201. The light-emitting layer 202 uses the excitation light L6 to generate photoluminescence.

[0155] Photoluminescence is controlled by light distribution in the light conversion component 201 and designed in the design section 202 of the light-emitting layer 202. The light-controlled and designed photoluminescence, as light (red light) L8 from the light source section 2C, is emitted from the light conversion component 201 outside the lamp chamber 102 through the excitation light blocking component 203 into the reflector section 3C inside the lamp chamber 102.

[0156] The light L8 incident on the reflector 3C is reflected in the reflector 3C in a predetermined direction by light distribution control. The reflected light L9 is emitted as the outgoing light L9 and passes through the lamp lens 101 from inside the lamp chamber 102, and then is emitted from the front side of the vehicle V to the rear side in a predetermined direction out of the lamp chamber 102. That is, the light distribution illuminates the rear side of the vehicle V for the purpose of taillights.

[0157] The emitted light L9 enters the eye point IP2 of a person located at the rear of the vehicle V outside the lamp chamber 102, thereby making the luminous surface of the taillight function visible by emitting light in the lamp lens 101.

[0158] Furthermore, the excitation light L7 that does not pass through the light-emitting layer 202 of the light conversion component 201 is absorbed by the excitation light blocking component 203. As a result, the excitation light L6 and L7 do not enter the lamp chamber 102. Therefore, within the lamp chamber 102, the light L8 and the emitted light L9 from the light source 2 can be seen, but the excitation light L6 and L7 cannot be seen. That is, within the lamp chamber 102, there is no sense of disharmony caused by the coexistence of light L8 and the emitted light L9 from the light source 2 and the excitation light L6 and L7, which have different colors.

[0159] (Explanation of the effects of Implementation Method 4)

[0160] The vehicle lamp 1C of this embodiment 4 has the structure and function described above. Hereinafter, its effects will be explained.

[0161] The vehicle lamp 1C of this embodiment 4 has the structure and function described above, and therefore can achieve the same effect as the vehicle lamps 1 to 1B of embodiments 1 to 3 described above.

[0162] In particular, in the vehicle lamp 1C of this embodiment 4, photoluminescence generated by irradiating the light-emitting layer 202 of the light-emitting member 201 with excitation light L6 from the excitation light source 200 is used as light L8 from the light source unit 2C. As a result, the vehicle lamp 1C of this embodiment 4 has a lower manufacturing cost than OLED (organic LED), can improve the reliability of the light source, and can achieve surface emission in the lamp lens 101 in the same way as OLED (organic LED).

[0163] Furthermore, in the vehicle lamp 1C of this embodiment 4, an excitation light blocking member 203 is disposed between the excitation light source 200 side, the reflector 3C, and the lamp lens 101 side to block the excitation light L7 of the light-emitting layer 202 that does not pass through the light conversion member 201. As a result, in the vehicle lamp 1C of this embodiment 4, a colorless lamp lens (transparent lamp lens) can be used as the lamp lens 101 instead of a colored lamp lens that absorbs the excitation light L7. Thus, in the vehicle lamp 1C of this embodiment 4, when the light source 2C is not lit, when observing the lamp chamber 102 through the colorless lamp lens 101, the reflector 3C of the transparent component inside the lamp chamber 102 is not visible, and the lamp chamber 102 appears to be an almost completely transparent space. On the other hand, when the light source 2C is lit, the reflector 3C can be seen through the colorless lamp lens 101 as the light-emitting surface.

[0164] In the vehicle lamp 1C of this embodiment 4, the excitation light blocking component 203 is made of a component that allows photoluminescence (red light) to pass through and absorbs excitation light L6, L7 (especially leakage excitation light L7), so the structure is simple and the manufacturing cost is low.

[0165] In the vehicle lamp 1C of this embodiment 4, an external light absorption layer 40 is provided on the inner surface of the lamp housing 100 to absorb external light L4 after it passes through the reflector 3C. As a result, in the vehicle lamp 1C of this embodiment 4, when not lit, the following situation does not occur: external light L4 is reflected by the inner surface of the lamp housing 100, and the light source 2C and the like are reflected into the reflector 3C and can be seen according to the line of sight from the eyepoint IP2 outside the lamp chamber 102. That is, in the vehicle lamp 1C of this embodiment 4, when not lit, the reflector 3C inside the lamp chamber 102 is almost completely invisible.

[0166] In the vehicle lamp 1C of this embodiment 4, since the light conversion member 201 is provided with a design portion 202 (light-emitting layer 202) for designing the pattern of the emitted light L9 emitted towards the lamp chamber 12, it is possible to obtain light distribution with a predetermined lamp function and light distribution with arbitrary patterns. Moreover, since the design portion 202 (light-emitting layer 202) is composed of a diffuse surface, it is possible to obtain surface-emitting light distribution.

[0167] In the vehicle lamp 1C of this embodiment 4, when the reflector 3C is composed of a multi-plate component, a novel light distribution function can be obtained.

[0168] In the vehicle lamp 1C of this embodiment 4, when there are multiple excitation light sources 200, the lighting and extinguishing of each of the multiple excitation light sources 200 can be controlled, thus achieving dynamic light-emitting surface and light distribution. Furthermore, the reflector 3C becomes a component with display function.

[0169] (Explanation of the structure, function, and effects of Implementation Method 5)

[0170] Figure 9 Embodiment 5 of the vehicle lamp of the present invention is shown. Hereinafter, the structure, function, and effects of the vehicle lamp 1D of Embodiment 5 will be described. In the accompanying drawings, [the following text is incomplete and likely refers to a different embodiment of the invention]. Figures 1 to 8 The same symbol represents the same item.

[0171] The vehicle lamp 1D of this embodiment 5 is a variation of the vehicle lamp 1C of embodiment 4 described above. Furthermore, the light source portion 2D and the reflector portion 3D of the vehicle lamp 1D of this embodiment 5 are constructed with the same structure as the light source portion 2C and the reflector portion 3C of the vehicle lamp 1C of embodiment 4 described above.

[0172] The structure of the excitation light blocking member 204 of the vehicle lamp 1D in this embodiment 5 differs from the structure of the excitation light blocking member 203 of the vehicle lamp 1C in embodiment 4 described above. The excitation light blocking member 204 of the vehicle lamp 1D in this embodiment 5 has a transmissive portion 205 that allows photoluminescence (red light L8) to pass through, and an opaque portion 206 that prevents excitation light L6 and L7 (especially leakage excitation light L7) from passing through.

[0173] The vehicle lamp 1D of this embodiment 5 can achieve the same effect as the vehicle lamp 1C of embodiment 4 described above.

[0174] (Explanation of the structure, function, and effects of Implementation Method 6)

[0175] Figure 10 and Figure 11 Embodiment 6 of the vehicle lamp of the present invention is shown. Hereinafter, the structure, function, and effects of the vehicle lamp 1E of Embodiment 6 will be described. In the accompanying drawings, [the following text is incomplete and likely refers to a different embodiment]. Figures 1-9 The same symbol represents the same item.

[0176] The vehicle lamp 1E of this embodiment 6 is a variation of the vehicle lamps 1C and 1D of embodiments 4 and 5 described above. Furthermore, the light source 2E and the reflector 3E of the vehicle lamp 1E of this embodiment 6 are constructed with the same structure as the light source 2C and 2D and the reflector 3C and 3D of the vehicle lamps 1C and 1D of embodiments 4 and 5 described above.

[0177] In the vehicle lamps 1C and 1D of embodiments 4 and 5 described above, by using excitation light blocking components 203 and 204, a colorless lamp lens can be used as the lamp lens 101. As a result, when not lit, the lamp chamber 102 appears to be almost completely transparent without the reflective part 3C.

[0178] In contrast, in the vehicle lamp 1E of this embodiment 6, the excitation light blocking components 203 and 204 are not used. Instead, the lamp lens 103 uses a component that allows photoluminescence (red light L8) to pass through and absorbs excitation light L6 and L7 (especially leakage excitation light L7). In this example, the lamp lens 103 is made of a red transparent component.

[0179] As a result, the vehicle lamp 1E of this embodiment 6 can achieve the same effect as the vehicle lamps 1C and 1D of embodiments 4 and 5 described above.

[0180] In particular, since the vehicle lamp 1E of this embodiment 6 does not use the excitation light blocking components 203 and 204 used in the vehicle lamps 1C and 1D of the above embodiments 4 and 5, the structure is simple and the manufacturing cost is low.

[0181] Furthermore, in the vehicle lamp 1E of this embodiment 6, the lamp housing 100 and the external light-absorbing layer 40 may be omitted. In this case, the lamp lens 103 remains unchanged. Also, in this case, a patterned component (see reference) is provided. Figure 6 The pattern component 4) is positioned on the side opposite to the lamp lens 103, relative to the reflective part 3E.

[0182] Therefore, the pattern component of the vehicle lamp 1E in Embodiment 6 can achieve the same effect as the pattern component 4 of the vehicle lamp 1B in Embodiment 3 described above. That is, when the reflective portion 3E on the inner side of the lamp lens 103 is viewed from the outside of the lamp lens 103, the pattern on the front side of the pattern component can be seen, and the back side of the pattern component can be covered to hide it.

[0183] Furthermore, in the vehicle lamp 1E of this embodiment 6, the lamp lens 103, together with the reflector 3E, can cover the light source 2E to replace the vehicle body panel P, which is a shielding component.

[0184] (Explanation of the structure, function, and effects of Implementation Method 7)

[0185] Figure 12 Embodiment 7 of the vehicle lamp of the present invention is shown. Hereinafter, the structure, function, and effects of the vehicle lamp 1F of Embodiment 7 will be described. In the accompanying drawings, [the following text is incomplete and likely refers to a different embodiment of the invention]. Figures 1 to 11 The same symbol represents the same item.

[0186] The vehicle lamp 1F of this embodiment 7 is a variation of the vehicle lamp E of embodiment 6 described above. Furthermore, the reflector 3F of the vehicle lamp 1F of this embodiment 7 has the same structure as the reflector 3E of the vehicle lamp 1E of embodiment 6 described above.

[0187] In the vehicle lamp 1E of the above-described embodiment 6, the light source 2E is used as the light source unit 2E, which has a light conversion component 201 and a light-emitting layer 202 (design part 202), and the lamp lens 103 is used as the lamp lens 103, which is made of a red transparent component.

[0188] In contrast, in the vehicle lamp 1F of this embodiment 7, the light source 2F uses one or more light sources 210 (such as red LED 210, red LD (semiconductor laser) in this example) that emit light L10 (red light L10 in this example) and an optical substrate 208, and the lamp lens 104 uses a lamp lens 104 made of a colorless transparent component.

[0189] An optical substrate 208 is disposed between the light source 210 and the reflector 3F, and is optically designed thereon. The optical substrate 208 has a design portion 209 for designing the pattern of the outwardly emitted light L11 (red light L11). In this example, the design portion 209 is provided on a part of the optical substrate 208. Alternatively, the design portion 209 may be provided on the entire optical substrate 208. The design portion 209 is composed of a diffuse surface.

[0190] As a result, the vehicle lamp 1F of this embodiment 7 can achieve the same effect as the vehicle lamps 1C to 1E of embodiments 4 to 6 described above.

[0191] (Explanation of the structure, function, and effects of Implementation Method 8)

[0192] Figure 13 Embodiment 8 of the vehicle lamp of the present invention is shown. Hereinafter, the structure, function, and effects of the vehicle lamp 1G of Embodiment 8 will be described. In the accompanying drawings, [the following text is incomplete and likely refers to a different embodiment of the invention]. Figures 1-12 The same symbol represents the same item.

[0193] The vehicle lamp 1G of this embodiment 8 is a variation of the vehicle lamps 1E and 1F of embodiments 6 and 7 described above. Furthermore, the reflector 3G of the vehicle lamp 1G of this embodiment 8 has the same structure as the reflectors 3E and 3F of the vehicle lamps 1E and 1F of embodiments 6 and 7 described above.

[0194] In the vehicle lamp 1G of this embodiment 8, the light source unit 2G has multiple light sources, five in this example, 211, 212, 213, 214, and 215 (hereinafter referred to as "211 to 215"). The multiple light sources 211 to 215 are configured to be individually controlled to be lit and extinguished via a control unit (not shown).

[0195] The light source 2G of the vehicle lamp 1G in this embodiment 8 can be used as the light source 2A to 2F of the vehicle lamps 1A to 1F in the embodiments 1 to 7 described above.

[0196] The vehicle lamp 1G of this embodiment 8 can achieve the same effect as the vehicle lamps 1C to 1F of embodiments 4 to 7 described above. In particular, in the vehicle lamp 1F of this embodiment 8, since the lighting and extinguishing of the multiple light sources 211 to 215 of the light source section 2 can be controlled individually, dynamic light-emitting surface and light distribution can be obtained. Moreover, the reflector section 3G becomes a component with display function.

[0197] (Explanation of examples other than implementation methods 1 to 8)

[0198] Furthermore, in embodiments 1 to 8 described above, any one of the taillights, brake lights, or rear brake lights constituting the rear combination lamps was explained. However, the present invention can also be applied to vehicle lighting devices other than the aforementioned lamps or displays. For example, turn signals, rear fog lights, and reversing lights at the rear of a vehicle.

[0199] Furthermore, in embodiments 1 to 8 described above, the rear combination lamp equipped at the rear of the vehicle was explained. However, in addition to the rear combination lamp equipped at the rear of the vehicle, the present invention can also be applied to the front combination lamp, interior lamp, instrument lamp, decorative lamp, display, etc., equipped at the front of the vehicle. Examples of front combination lamps include headlights, fog lights, daytime running lights, vehicle width lights, and turn signals.

[0200] Furthermore, in embodiments 1 to 8 described above, the light source units 2 to 2G are mounted on the roof portion of the vehicle body panel P.
