Abstract

An image-generating member (40) for generating an image serving as a basis for a rendering light distribution pattern is arranged between a light-emitting element (20) and a projection lens (30). The image-generating member (40) is constituted by a light-transmitting member, and a portion of an emission surface (42a) is configured as a light-transmitting region (42aA), and a peripheral region is configured as a light-shielding region (42aB) in which a plurality of corner cubes (50) are formed. As a result, an image serving as a basis for a rendering light distribution pattern is generated by the light-transmitting region (42aA), while light reaching the light-shielding region (42aB) is retroreflected toward an incident surface (42b) side of the image-generating member (40) by the plurality of corner cubes (50) so as not to be emitted into a space on a front side of the lamp.

Description

TECHNICAL FIELD

[0001] The present disclosure relates to a rendering lamp configured to form a rendering light distribution pattern.BACKGROUND ART

[0002] In the related art, as a rendering lamp for forming a rendering light distribution pattern (i.e., a light distribution pattern for rendering a character, a symbol, or the like on a road surface ahead of a lamp), a lamp configured to irradiate light emitted from a light-emitting element toward a front of the lamp through a projection lens has been known.

[0003] Patent Literature 1 describes, as a configuration of an in-vehicle rendering lamp, a configuration in which a light-shielding plate is arranged between a light-emitting element and a projection lens as an image-generating member for generating an image serving as a basis for a rendering light distribution pattern. That is, in the rendering lamp described in Patent Literature 1, the image is generated by an opening portion formed in the light-shielding plate.

[0004] In addition, Patent Literature 2 describes, as a configuration of such a rendering lamp, a configuration in which a light guide member is arranged between a light-emitting element and a light-shielding plate.CITATION LISTPATENT LITERATURE

[0005] Patent Literature 1: International Publication No. WO2022 / 019231 Patent Literature 2: JP2019-192350A SUMMARY OF INVENTIONTECHNICAL PROBLEM

[0006] In such an in-vehicle rendering lamp, by forming a rendering light distribution pattern by the irradiated light therefrom, it is possible to indicate intention of an own vehicle to surroundings during traveling of a vehicle at night or the like, thereby making it possible to prompt attention of other vehicles, pedestrians, or the like.

[0007] As in the rendering lamp described in Patent Literature 2, when a configuration is adopted in which a light guide member is arranged between a light-emitting element and a light-shielding plate, it becomes possible to increase utilization efficiency of light emitted from the light-emitting element. However, the addition of the light guide member increases the cost of the rendering lamp.

[0008] On the other hand, in such a rendering lamp, when, as a configuration of a distal end surface of the light guide member, a light diffusion treatment such as embossing is applied to a region other than a region for generating an image serving as a basis for a rendering light distribution pattern, it becomes possible to provide the light guide member itself with an image-generating function. This makes it possible to eliminate the light-shielding plate and to reduce the cost of the rendering lamp.

[0009] However, when such a configuration is adopted, the distal end surface of the light guide member is also seen to glow faintly in a region other than the region for generating the image due to transmission of diffused light, making it impossible to form a clear rendering light distribution pattern.

[0010] Such a problem may similarly arise also in rendering lamps other than in-vehicle rendering lamps.

[0011] An object of the present disclosure is to provide a rendering lamp configured to form a rendering light distribution pattern and capable of increasing utilization efficiency of light emitted from a light-emitting element by a low-cost configuration, and also forming a clear rendering light distribution pattern.SOLUTION TO PROBLEM

[0012] The present disclosure seeks to achieve the above-described object by conceiving a configuration of an image-generating member.

[0013] That is, a rendering lamp according to the present disclosure is a rendering lamp configured to form a rendering light distribution pattern, the rendering lamp including: a light-emitting element; a projection lens configured to irradiate light emitted from the light-emitting element toward a front of the lamp; and an image-generating member arranged between the light-emitting element and the projection lens, and configured to generate an image that serves as a basis for the rendering light distribution pattern by shielding a portion of the light emitted from the light-emitting element, wherein the image-generating member is constituted by a light-transmitting member having an incident surface on which light emitted from the light-emitting element is incident and an emission surface from which the incident light from the incident surface is emitted, the emission surface includes a partial region configured as a light-transmitting region for generating the image, and a peripheral region of the partial region configured as a light-shielding region, and the light-shielding region includes a plurality of corner cubes formed on the emission surface.

[0014] The "rendering lamp" may be an in-vehicle lamp, or may be a lamp used for applications other than in-vehicle use.

[0015] The "image-generating member" is constituted by a light-transmitting member, but specific shapes of an incident surface and an emission surface thereof are not particularly limited.

[0016] The "light-shielding region" is formed by forming a plurality of corner cubes on the emission surface of the image-generating member, but a specific arrangement of the plurality of corner cubes, and a size, a shape, and the like of each corner cube are not particularly limited.ADVANTAGEOUS EFFECTS OF INVENTION

[0017] The rendering lamp according to the present disclosure is configured to form a rendering light distribution pattern by irradiating light emitted from the light-emitting element toward the front of the lamp through the projection lens. The image-generating member arranged between the light-emitting element and the projection lens is constituted by the light-transmitting member having an incident surface configured to cause light emitted from the light-emitting element to be incident thereon and an emission surface configured to cause the incident light from the incident surface to be emitted therefrom. The emission surface of the image-generating member includes a portion configured as a light-transmitting region and a peripheral region includes configured as a light-shielding region, and furthermore, the light-shielding region is formed by forming the plurality of corner cubes on the emission surface. As a result, the following effects can be obtained.

[0018] That is, in the rendering lamp according to the present disclosure, an image serving as a basis for a rendering light distribution pattern is generated by the light-transmitting region of the emission surface of the image-generating member, but the peripheral light-shielding region is formed by forming the plurality of corner cubes on the emission surface of the image-generating member. As a result, light that reaches the light-shielding region becomes light that is retroreflected toward the incident surface side, and is not emitted into a space on the front side of the lamp.

[0019] Accordingly, the image generated on the emission surface of the image-generating member becomes clear, and the rendering light distribution pattern is also formed as a clear light distribution pattern. Furthermore, such a clear light distribution pattern can be achieved while reducing the cost of the rendering lamp by eliminating the light-shielding plate of the related art.

[0020] In this way, according to the present disclosure, in a rendering lamp configured to form a rendering light distribution pattern, utilization efficiency of light emitted from the light-emitting element can be increased by a low-cost configuration, and a clear rendering light distribution pattern can be formed.

[0021] In addition, in the above configuration, when a boundary line between the light-transmitting region and the light-shielding region of the emission surface of the image-generating member is fomred by ridge lines of the plurality of corner cubes, an image generated on the emission surface of the image-generating member can be made clearer. As a result, the rendering light distribution pattern can also be formed as a clearer light distribution pattern.

[0022] In the above configuration, further, when the light-emitting element is mounted on a white substrate, the following operational effects can be obtained.

[0023] That is, light that is incident on the image-generating member and then reaches the light-shielding region of the emission surface is retroreflected toward the incident surface side, and then most of the light is emitted from the incident surface into a space on a rear side of the lamp, but this emitted light becomes light directed toward a vicinity of the light-emitting element.

[0024] Therefore, when the substrate on which the light-emitting element is mounted is configured as a white substrate, it becomes possible to reflect the retroreflected light reaching the white substrate in a region in the vicinity of the light-emitting element and to reuse the reflected light as light directed toward the incident surface of the image-generating member.

[0025] By causing the reflected light from the white substrate to be incident on the image-generating member, an image serving as a basis for the rendering light distribution pattern can be brightened, thereby increasing a brightness of the rendering light distribution pattern.

[0026] In the above configuration, when the emission surface of the image-generating member is formed to extend along a plane, the plurality of corner cubes can be formed with high precision. Therefore, light reaching the light-shielding region can be reliably retroreflected by the plurality of corner cubes, thereby facilitating clear formation of an image generated on the emission surface of the image-generating member and a rendering light distribution pattern.

[0027] In the above configuration, further, when the plurality of corner cubes are formed so as to be recessed portions with respect to the emission surface of the image-generating member, it becomes easy, as a structure of a mold for forming the image-generating member, to configure a portion corresponding to the light-shielding region as an insert. As a result, the image-generating member can be formed at low cost.

[0028] In the above configuration, further, when the light-transmitting member is constituted by a colored transparent resin member, a rendering light distribution pattern can be formed as a colored light distribution pattern even in a case in which the light-emitting element is configured as a white light-emitting diode or the like.

[0029] When the rendering lamp is configured to be turned on in synchronization with turning on of a turn signal lamp, and the light-transmitting member is constituted by an amber-colored resin member, a rendering light distribution pattern having the same amber color as a light-emitting color of the turn signal lamp can be formed.

[0030] In the above configuration, further, when the light-transmitting member is configured such that the light-transmitting region of the emission surface thereof is formed in a concave curved surface shape, an image serving as a basis for a rendering light distribution pattern can be formed as an image with less influence of field curvature, thereby making it possible to form the rendering light distribution pattern as a clearer light distribution pattern.BRIEF DESCRIPTION OF DRAWINGS

[0032] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.

[0033] Fig. 1 is a front view illustrating a rendering lamp 10 according to one embodiment of the present disclosure. Fig. 2 is a cross-sectional view taken along line II-II of Fig. 1, and Fig. 3 is a cross-sectional view taken along line III-III of Fig. 1.

[0034] In Figs. 1 and 3, a direction indicated by X is the "front of the lamp," a direction indicated by Y is a "leftward direction" (or a "rightward direction" when viewed from the front of the lamp) orthogonal to the "front of the lamp," and a direction indicated by Z is an "upward direction." The same applies to the drawings other than Figs. 1 to 3.

[0035] Before describing the specific configuration of the rendering lamp 10 according to the present embodiment, an outline thereof will be described.

[0036] Figs. 5 and 6 are a side view and a plan view illustrating the rendering lamp 10 mounted on a vehicle 100.

[0037] As illustrated in Figs. 5 and 6, the rendering lamp 10 is mounted at an end portion, in a vehicle width direction, of a front end portion of the vehicle 100, and is configured to irradiate light obliquely downward toward the outside in the vehicle width direction. The rendering lamp 10 is configured to be turned on in synchronization with turning on of a front turn signal lamp 12 and to form a rendering light distribution pattern PA on a road surface 2 ahead of the vehicle. Note that Fig. 6 illustrates a state in which the left rendering lamp 10 and the front turn signal lamp 12 are lit.

[0038] Note that, as illustrated in Figs. 5 and 6, when the rendering lamp 10 is mounted on the vehicle 100, the front of the lamp is set to be inclined obliquely downward with respect to a front-rear direction of the vehicle, but as illustrated in Figs. 1 to 3, when the rendering lamp 10 is in a standalone state, the front of the lamp is set to face in a horizontal direction.

[0039] Next, a specific configuration of the rendering lamp 10 will be described.

[0040] As illustrated in Figs. 1 to 3, the rendering lamp 10 is configured to irradiate light emitted from a light-emitting element 20 toward the front of the lamp through a projection lens 30.

[0041] The projection lens 30 includes a projection lens portion 32 serving as a lens body, and an outer peripheral flange portion 34 surrounding the projection lens portion 32.

[0042] The projection lens portion 32 is a plano-convex lens having a front surface 32a configured as a convex curved surface, and has an optical axis Ax extending in the front-rear direction of the lamp. The projection lens portion 32 has a rectangular external shape (specifically, a substantially square shape) when viewed from the front of the lamp.

[0043] The outer peripheral flange portion 34 is formed to be flush with a rear surface 32b of the projection lens portion 32 and to extend along a vertical plane orthogonal to the optical axis Ax, and is provided with a pair of attachment flange portions 36 formed on both left and right sides thereof. The pair of left and right attachment flange portions 36 has an L-shaped horizontal cross-sectional shape, and rear end surfaces thereof extend along the vertical plane orthogonal to the optical axis Ax so as to pass through a rear focus F of the projection lens 30.

[0044] The light-emitting element 20 is a white light-emitting diode and has a rectangular (specifically, square) light-emitting surface 20a. The light-emitting element 20 is mounted on a substrate 22 with the light-emitting surface 20a facing a frontward direction of the lamp and a light-emitting center thereof (i.e., a center point of the light-emitting surface 20a) positioned on the optical axis Ax. The substrate 22 is supported on a heat sink 60 in an arrangement in which the substrate extends along the vertical plane orthogonal to the optical axis Ax.

[0045] An image-generating member 40 configured to generate an image serving as a basis for the rendering light distribution pattern PA by blocking a portion of light directed from the light-emitting element 20 toward the projection lens portion 32 is arranged between the light-emitting element 20 and the projection lens 30. The image-generating member 40 is constituted by a light-transmitting member, and includes a lens portion 42 that deflects and controls light emitted from the light-emitting element 20 and a flat plate portion 44 surrounding the lens portion. The light-transmitting member is configured as a colored transparent resin member. Specifically, the light-transmitting member is configured as a resin member having the same amber color as a light-emitting color of the turn signal lamp 12.

[0046] The lens portion 42 is configured as a plano-convex lens and has a circular external shape centered on the optical axis Ax when viewed from the front of the lamp. Specifically, the lens portion 42 has a rear surface configured as an incident surface 42b having a convex curved surface shape that deflects light emitted from the light-emitting center of the light-emitting element 20 to be incident toward the frontward direction of the lamp (i.e., a direction parallel to the optical axis Ax). In addition, the lens portion 42 has a front surface configured as an emission surface 42a that causes the incident light from the incident surface 42b to be emitted as it is toward the frontward direction of the lamp.

[0047] The emission surface 42a is configured such that a partial region thereof is configured as a light-transmitting region 42aA for generating an image serving as a basis for a rendering light distribution pattern PA, and a peripheral region thereof is configured as a light-shielding region 42aB. The light-shielding region 42aB is constituted by a plurality of corner cubes 50 formed on the emission surface 42a.

[0048] The image-generating member 40 is configured such that the light-transmitting region 42aA of the emission surface 42a of the lens portion 42 and the front surface of the flat plate portion 44 pass through the rear focus F of the projection lens 30 and lie on the same vertical plane orthogonal to the optical axis Ax.

[0049] Note that the specific configuration of the image-generating member 40 will be described below.

[0050] The heat sink 60 includes a main body portion 62 extending along the vertical plane orthogonal to the front-rear direction of the lamp, a plurality of heat dissipation fins 64 extending along the vertical plane from the main body portion 62 toward the rear of the lamp, and a pair of attachment flange portions 66 formed on both left and right sides of the main body portion 62.

[0051] The substrate 22 is positioned and supported in surface contact with the main body portion 62 of the heat sink 60 by fastening screws 72 at two locations on a diagonal line thereof.

[0052] In addition, the projection lens 30 and the image-generating member 40 are positioned and supported by fastening screws 74 to the pair of left and right attachment flange portions 66 of the heat sink 60 at two locations on a diagonal line thereof. The screw fastening is performed by common fastening with the pair of left and right attachment flange portions 36 of the projection lens 30 and both left and right end portions of the flat plate portion 44 of the image-generating member 40 overlapped with the pair of left and right attachment flange portions 66 of the heat sink 60.

[0053] Note that, as illustrated in Fig. 1, positioning pins 36a are formed at two locations on the diagonal line of the pair of left and right attachment flange portions 36 of the projection lens 30. On the other hand, pin insertion holes 44a and 66a for inserting the positioning pins 36a are formed in both left and right end portions of the flat plate portion 44 of the image-generating member 40 and in the pair of left and right attachment flange portions 66 of the heat sink 60, respectively.

[0054] Next, the specific configuration of the image-generating member 40 will be described.

[0055] Fig. 4 is a perspective view illustrating a main portion of the image-generating member 40, viewed from an oblique downward direction.

[0056] As illustrated in Fig. 4, the planar light-transmitting region 42aA of the emission surface 42a of the lens portion 42 is formed as a substantially V-shaped region substantially centered on the optical axis Ax, and the light-shielding region 42aB surrounding the light-transmitting region 42aA is formed such that the plurality of corner cubes 50 are formed to be recessed portions with respect to the emission surface 42a.

[0057] That is, each of the plurality of corner cubes 50 is formed to protrude in a triangular pyramidal shape toward the front side of the lamp from a position displaced by one step toward the rear side of the lamp with respect to the emission surface 42a. Each of the plurality of corner cubes 50 is set such that an apex position thereof is substantially flush with the emission surface 42a, and a length of one side (i.e., a ridge line) of an outer peripheral edge thereof is set to a value of substantially 1 to 3 mm.

[0058] As illustrated in Fig. 1, the plurality of corner cubes 50 are arranged two-dimensionally in a continuous manner such that, when viewed from the front of the lamp, upright equilateral-triangular corner cubes 50 and inverted equilateral-triangular corner cubes 50 are vertically adjacent to each other.

[0059] The light-transmitting region 42aA is configured by arranging two small upright equilateral triangles side by side along an upper side of a large inverted equilateral triangle, and is thereby set as the substantially V-shaped region. In addition, the light-shielding region 42aB surrounding the light-transmitting region 42aA is set as a hexagonal region slightly larger than the external shape of the incident surface 42b of the lens portion 42.

[0060] A boundary line L1 between the light-transmitting region 42aA and the light-shielding region 42aB is constituted by the ridge lines of the plurality of corner cubes 50. In addition, an outer peripheral edge L2 of the light-shielding region 42aB is also constituted by the ridge lines of the plurality of corner cubes 50.

[0061] As illustrated in Figs. 2 and 3, the image-generating member 40 is configured such that, among light incident from the incident surface 42b of the lens portion 42 and reaching the emission surface 42a, light reaching the light-transmitting region 42aA is emitted as it is toward a front space of the lamp. On the other hand, the image-generating member 40 is configured such that light reaching the light-shielding region 42aB is totally reflected (that is, is retroreflected) in a reverse direction toward the incident surface 42b by the plurality of corner cubes 50.

[0062] Note that, since the light-shielding region 42aB is set as a region larger than the external shape of the incident surface 42b of the lens portion 42, among light incident from the incident surface 42b of the lens portion 42 and reaching the emission surface 42a, all light other than light reaching the light-transmitting region 42aA is retroreflected.

[0063] Next, the rendering light distribution pattern PA illustrated in Figs. 5 and 6 will be described.

[0064] As described above, the rendering light distribution pattern PA is formed by light irradiated from the rendering lamp 10, but the rendering light distribution pattern PA is formed as a light distribution pattern having a substantially inverted V shape (i.e., a shape pointed toward the front of the lamp).

[0065] An image (i.e., an image serving as a basis for the rendering light distribution pattern PA) generated in the light-transmitting region 42aA of the emission surface 42a of the image-generating member 40 by light emitted from the light-emitting element 20 is formed in a substantially V shape, and the rendering light distribution pattern PA is formed as an inverted projected image of the image.

[0066] Next, operations of the present embodiment will be described.

[0067] The rendering lamp 10 according to the present embodiment is configured to form the rendering light distribution pattern PA by irradiating light emitted from the light-emitting element 20 toward the front of the lamp through the projection lens 30. The image-generating member 40 arranged between the light-emitting element 20 and the projection lens 30 is constituted by a light-transmitting member having the incident surface 42b configured to cause light emitted from the light-emitting element 20 to be incident thereon and the emission surface 42a configured to cause the incident light from the incident surface 42b to be emitted therefrom. The emission surface 42a of the image-generating member 40 is configured such that a portion thereof is configured as the light-transmitting region 42aA and the peripheral region thereof is configured as the light-shielding region 42aB, and further, the light-shielding region 42aB is constituted by the plurality of corner cubes 50 formed on the emission surface 42a. As a result, the following effects can be obtained.

[0068] That is, in the rendering lamp 10 according to the present embodiment, an image serving as a basis for the rendering light distribution pattern PA is generated by the light-transmitting region 42aA of the emission surface 42a of the image-generating member 40, but the peripheral light-shielding region 42aB is constituted by the plurality of corner cubes 50 formed on the emission surface 42a of the image-generating member 40. As a result, light reaching the light-shielding region 42aB becomes light that is retroreflected toward the incident surface 42b, and is not emitted into a space on the front side of the lamp.

[0069] Accordingly, the image generated on the emission surface 42a of the image-generating member 40 becomes clear, and the rendering light distribution pattern PA is also formed as a clear light distribution pattern. Furthermore, such a clear light distribution pattern can be achieved while reducing the cost of the rendering lamp 10 by eliminating the light-shielding plate of the related art.

[0070] In this way, according to the present embodiment, in the rendering lamp 10 configured to form the rendering light distribution pattern PA, utilization efficiency of light emitted from the light-emitting element 20 can be increased by a low-cost configuration, and the clear rendering light distribution pattern PA can be formed.

[0071] Furthermore, in the rendering lamp 10 according to the present embodiment, the boundary line L1 between the light-transmitting region 42aA and the light-shielding region 42aB of the emission surface 42a of the image-generating member 40 is constituted by the ridge lines of the plurality of corner cubes 50, and thus the image generated on the emission surface 42a of the image-generating member 40 can be made clearer. As a result, the rendering light distribution pattern PA can also be formed as a clearer light distribution pattern.

[0072] In addition, in the rendering lamp 10 according to the present embodiment, the emission surface 42a of the image-generating member 40 is formed to extend along a plane, and thus the plurality of corner cubes 50 can be formed with high precision. Therefore, light reaching the light-shielding region 42aB can be reliably retroreflected by the plurality of corner cubes 50, thereby facilitating clear formation of an image generated on the emission surface 42a of the image-generating member 40 and the rendering light distribution pattern PA.

[0073] Further, in the rendering lamp 10 according to the present embodiment, the plurality of corner cubes 50 are formed to be recessed portions with respect to the emission surface 42a of the image-generating member 40, and thus it becomes easy, as a structure of a mold for forming the image-generating member 40, to configure a portion corresponding to the light-shielding region 42aB as an insert. As a result, the image-generating member 40 can be formed at low cost.

[0074] In addition, the rendering lamp 10 according to the present embodiment is configured to be turned on in synchronization with turning on of the front turn signal lamp 12, but the light-transmitting member as the image-generating member 40 is configured as an amber-colored resin member. As a result, even when the light-emitting element 20 is configured as a white light emitting diode, it is possible to form the rendering light distribution pattern PA having the same amber color as the light-emitting color of the front turn signal lamp 12.

[0075] In the above embodiment, it has been described that the rendering lamp 10 is configured to be turned on in synchronization with turning on of the front turn signal lamp 12. However, the rendering lamp 10 may be configured to be turned on in synchronization with turning on of a rear turn signal lamp or the like.

[0076] In the above embodiment, the light-transmitting member as the image-generating member 40 has been described as being configured as an amber-colored resin member. However, another colored transparent resin member (e.g., a green or blue resin member) may also be adopted.

[0077] In the above embodiment, the light-transmitting region 42aA of the emission surface 42a of the image-generating member 40 has been described as having a substantially V-shaped external shape. However, a configuration having another external shape (for example, a downward arrow shape or an inverted trapezoidal shape) may also be adopted.

[0078] In the above embodiment, each of the plurality of corner cubes has been described as having an equilateral triangular external shape. However, a configuration having another external shape (for example, a regular hexagonal external shape) may also be adopted.

[0079] In the above embodiment, the boundary line L1 between the light-transmitting region 42aA and the light-shielding region 42aB of the emission surface 42a of the image-generating member 40 has been described as being constituted by the ridge lines of the plurality of corner cubes 50. However, a configuration in which the boundary line L1 is set to extend so as to intersect the ridge lines of the plurality of corner cubes 50 may also be adopted.

[0080] In the above embodiment, the light-emitting color of the light-emitting element 20 has been described as being white. However, another light-emitting color (e.g., amber or red) may also be adopted.

[0081] In the above embodiment, the rendering lamp 10 has been described as being mounted at the end portion, in the vehicle width direction, of the front end portion of the vehicle 100. However, a configuration in which the rendering lamp 10 is mounted at a rear end portion, a side surface portion, or the like of the vehicle 100 may also be adopted.

[0082] In the above embodiment, the rendering light distribution pattern PA has been described as being formed on the road surface 2 ahead of the vehicle by light irradiated from the rendering lamp 10. However, a configuration may also be adopted in which the rendering light distribution pattern is formed, for example, on a wall surface arranged at the front of the lamp, on a wall surface extending toward the front of the lamp, or the like.

[0083] Next, variations of the above embodiment will be described.

[0084] First, a first variation of the above embodiment will be described.

[0085] Fig. 7 is a view similar to Fig. 1, illustrating a vehicle lamp 110 according to the present variation.

[0086] As illustrated in Fig. 7, a basic configuration of the present variation is the same as that of the above embodiment, but the arrangement of the light-emitting element 20 is different from that of the above embodiment.

[0087] That is, in the rendering lamp 110 according to the present variation, the light-emitting element 20 is arranged at a position displaced downward with respect to the above embodiment (specifically, at a position directly below the optical axis Ax and overlapping a lower region of the light-transmitting region 42aA when viewed from the front of the lamp).

[0088] By adopting the configuration of the present variation, the following effects can be obtained.

[0089] That is, in the present variation as well, an image serving as a basis for the rendering light distribution pattern PA is generated in the light-transmitting region 42aA of the emission surface 42a of the image-generating member 40 by light emitted from the light-emitting element 20, but a brightness of a lower region of the image can be increased as compared with the above embodiment. As a result, the rendering light distribution pattern PA formed on the road surface 2 ahead of the vehicle can be formed as a light distribution pattern having substantially uniform brightness from a near-distance region to a far-distance region.

[0090] Next, a second variation of the above embodiment will be described.

[0091] Fig. 8 is a view similar to Fig. 3, illustrating a vehicle lamp 210 according to the present variation.

[0092] As illustrated in Fig. 8, a basic configuration of the present variation is the same as that of the above embodiment, but a configuration of a substrate 222 supporting the light-emitting element 20 is different from that of the above embodiment.

[0093] That is, in the rendering lamp 210 according to the present variation, the substrate 222 is configured as a white substrate.

[0094] Specifically, the substrate 222 of the present variation is configured such that a white film 224 is formed on a surface thereof (i.e., a mounting surface for the light-emitting element 20). The coating film 224 is constituted by a resist layer covering a copper foil (not illustrated) formed as a wiring pattern on the surface of the substrate 222.

[0095] By adopting the configuration of the present variation, the following effects can be obtained.

[0096] As illustrated in Fig. 8, light emitted from the light-emitting surface 20a of the light-emitting element 20 and incident on the image-generating member 40 reaches the light-shielding region 42aB of the emission surface 42a, and is then retroreflected toward the incident surface 42b side by the plurality of corner cubes 50 constituting the light-shielding region 42aB. However, most of the retroreflected light becomes light that is emitted from the incident surface 42b into a space on the rear side of the lamp. Note that, in Fig. 8, optical paths of light emitted from a center position and upper and lower end positions of the light-emitting surface 20a of the light-emitting element 20 are illustrated.

[0097] In this way, the retroreflected light emitted from the incident surface 42b of the image-generating member 40 into the space on the rear side of the lamp becomes light directed toward a vicinity of the light-emitting element 20 (i.e., the light-emitting surface 20a or a peripheral region of the light-emitting surface 20a on the substrate 222).

[0098] Therefore, as in the present variation, by configuring the substrate 222 on which the light-emitting element 20 is mounted as a white substrate, the retroreflected light that reaches the substrate 222 can be reflected in the vicinity of the light-emitting element 20 and reused as light directed toward the incident surface 42b of the image-generating member 40.

[0099] By causing the reflected light from the white substrate 222 to be incident on the image-generating member 40, an image serving as a basis for the rendering light distribution pattern PA can be brightened, thereby increasing the brightness of the rendering light distribution pattern PA.

[0100] Next, a third variation of the above embodiment will be described.

[0101] Fig. 9 is a view similar to Fig. 1, illustrating a vehicle lamp 310 according to the present variation.

[0102] As illustrated in Fig. 9, a basic configuration of the present variation is the same as that of the above embodiment, but the number and arrangement of light-emitting elements 20 and a configuration of an image-generating member 340 are different from those of the above embodiment.

[0103] That is, the rendering lamp 310 according to the present variation includes three light-emitting elements 20. The three light-emitting elements 20 are arranged at a position directly below the optical axis Ax and at upper-left and upper-right positions.

[0104] The image-generating member 340 of the present variation, like the image-generating member 40 of the above embodiment, is constituted by a light-transmitting member and includes a lens portion 342 that deflects and controls light emitted from the three light-emitting elements 20, and a flat plate portion 344 surrounding the lens portion 342.

[0105] The lens portion 342 is, as in the above embodiment, a plano-convex lens, and has a rear surface configured as an incident surface 342b having a convex curved surface shape, and a front surface configured as an emission surface 342a. The emission surface 342a of the lens portion 342 has three regions configured as light-transmitting regions 342aA, and a peripheral region configured as a light-shielding region 342aB.

[0106] The three light-transmitting regions 342aA are arranged in a V shape to correspond to the three light-emitting elements 20, and each of the three light-transmitting regions has a substantially V-shaped external shape smaller than that of the above embodiment.

[0107] On the other hand, the light-shielding region 342aB is constituted by a plurality of corner cubes 350 formed on the emission surface 342a, as in the above embodiment.

[0108] Fig. 11A is a plan view illustrating a rendering light distribution pattern PB formed by light irradiated from the rendering lamp 310 according to the present variation.

[0109] As illustrated in Fig. 11A, the rendering light distribution pattern PB is composed of three light distribution patterns PBa, PBb, and PBc.

[0110] The three light distribution patterns PBa to PBc are all inverted V-shaped (i.e., pointed toward the front of the lamp) light distribution patterns that are smaller than the rendering light distribution pattern PA of the above embodiment, and are formed at substantially equal intervals in an inverted V-shaped arrangement on the road surface 2 ahead of the vehicle.

[0111] Three images (i.e., images serving as bases for the three light distribution patterns PBa to PBc) generated in the light-transmitting regions 342aA of the emission surface 342a of the image-generating member 340 by light emitted from the three light-emitting elements 20 are formed in a substantially V shape in a V-shaped arrangement, and the rendering light distribution pattern PB is formed as inverted projected images of the images.

[0112] By adopting the configuration of the present variation, the rendering light distribution pattern PB can be formed as a light distribution pattern composed of three clear light distribution patterns PBa to PBc formed in a substantially V shape in a V-shaped arrangement.

[0113] Furthermore, in the rendering lamp 310 according to the present variation, the three light-emitting elements 20 are arranged at positions corresponding to the three light-transmitting regions 342aA, and thus three light distribution patterns PBa to PBc can be formed as bright light distribution patterns.

[0114] Next, a fourth variation of the above embodiment will be described.

[0115] Fig. 10 is a view similar to Fig. 3, illustrating a vehicle lamp 410 according to the present variation.

[0116] As illustrated in Fig. 10, a basic configuration of the present variation is similar to that of the above embodiment, but is different from the above embodiment in that an image-generating member 440 includes three lens portions 442. In addition, the number of light-emitting elements 20 and configurations of a projection lens 430, a substrate 422, and a heat sink 460 are different from those of the above embodiment.

[0117] That is, in the image-generating member 440 of the present variation, three lens portions 442 are arranged in series in the vertical direction. A central lens portion 442 is positioned on the optical axis Ax, and a pair of upper and lower lens portions 442 is arranged at positions equidistant from the optical axis Ax.

[0118] The three lens portions 442 are, as in the lens portion 42 of the above embodiment, all plano-convex lenses, and each have a rear surface configured as an incident surface 442b having a convex curved surface shape, and a front surface configured as an emission surface 442a. However, a size of each of the three lens portions 442 is smaller than that of the lens portion 42 of the above embodiment.

[0119] The emission surface 442a of each of the three lens portions 442 is configured such that a partial region thereof is configured as a light-transmitting region 442aA and a peripheral region thereof is configured as a light-shielding region 442aB. The three light-transmitting regions 442aA all have a substantially V-shaped external shape smaller than the light-transmitting region 42aA of the above embodiment. In addition, the light-shielding region 442aB is constituted by a plurality of corner cubes 450 formed on the emission surface 442a, as in the above embodiment. However, each of the plurality of corner cubes 450 is smaller in size than that of the above embodiment.

[0120] The projection lens 430 of the present variation includes a projection lens portion 432 configured as a plano-convex lens and an outer peripheral flange portion 434, similarly to the projection lens 30 of the above embodiment, but a size of the projection lens portion 432 is larger than that of the above embodiment.

[0121] In the present variation, the three light-emitting elements 20 are mounted on the substrate 422 in an arrangement in which they are positioned on the rear side of the lamp with respect to the three lens portions 442, and the substrate 422 is supported on the heat sink 460.

[0122] Fig. 11B is a plan view illustrating a rendering light distribution pattern PC formed by light irradiated from the rendering lamp 410 according to the present variation.

[0123] As illustrated in Fig. 11B, the rendering light distribution pattern PC is composed of three light distribution patterns PCa, PCb, and PCc.

[0124] The three light distribution patterns PCa to PCc are all inverted V-shaped (i.e., pointed toward the front of the lamp) light distribution patterns that are smaller than the rendering light distribution pattern PA of the above embodiment, and are formed at substantially equal intervals in a serial arrangement on the road surface 2 ahead of the vehicle.

[0125] Three images (i.e., images serving as bases for the three light distribution patterns PCa to PCc) generated in the light-transmitting regions 442aA of the emission surfaces 442a of the three lens portions 442 of the image-generating member 440 by light emitted from the three light-emitting elements 20 are formed in a substantially V shape in a serial arrangement, and the rendering light distribution pattern PC is formed as inverted projected images of the images.

[0126] By adopting the configuration of the present variation, the rendering light distribution pattern PC can be formed as a light distribution pattern composed of three clear light distribution patterns PCa to PCc formed in a substantially V shape in a serial arrangement.

[0127] Furthermore, in the rendering lamp 410 according to the present variation, the three light-emitting elements 20 are arranged at positions corresponding to the three light-transmitting regions 442aA, and thus three light distribution patterns PCa to PCc can be formed as bright light distribution patterns.

[0128] Next, a fifth variation of the above embodiment will be described.

[0129] Fig. 12 is a view similar to Fig. 1, illustrating a vehicle lamp 510 according to the present variation. In addition, Fig. 13 is a view similar to Fig. 4, illustrating an image-generating member 540 of the rendering lamp 510.

[0130] As illustrated in Figs. 12 and 13, a basic configuration of the present variation is the same as that of the above embodiment, but a configuration of an image-generating member 540 is partially different from that of the above embodiment.

[0131] That is, the image-generating member 540 of the present variation is also constituted by a light-transmitting member (specifically, an amber-colored resin member), and includes a lens portion 542 that deflects and controls light emitted from the light-emitting element 20 and a flat plate portion 544 surrounding the lens portion. The image-generating member 540 is configured such that a light-transmitting region 542aA of an emission surface 542a of the lens portion 542 and a front surface 544a of the flat plate portion 544 are both vertical planes orthogonal to the optical axis Ax. However, the light-transmitting region 542aA is positioned on a vertical plane passing through the rear focus F of the projection lens 30, whereas the front surface 544a of the flat plate portion 544 is positioned on a vertical plane displaced toward the rear side of the lamp with respect to the light-transmitting region 542aA.

[0132] In the emission surface 542a of the lens portion 542, the light-transmitting region 542aA is set as a flat V-shaped (so-called chevron-shaped) region substantially centered on the optical axis Ax when viewed from the front of the lamp. The light-shielding region 542aB surrounding the light-transmitting region 542aA is set as a rectangular region that is slightly larger than an external shape of an incident surface 542b of the lens portion 542.

[0133] In the light-shielding region 542aB, a plurality of corner cubes 550, each having a regular hexagonal external shape when viewed from the front of the lamp, are arranged two-dimensionally in a continuous manner. The plurality of corner cubes 550 are formed to be recessed portions with respect to the front surface 544a of the flat plate portion 544.

[0134] That is, each of the plurality of corner cubes 550 is formed to protrude in a triangular pyramidal shape toward the front side of the lamp from a position displaced by one step toward the rear side of the lamp with respect to the front surface 544a of the flat plate portion 544. Each of the plurality of corner cubes 550 is set such that an apex position thereof is substantially flush with the front surface 544a of the flat plate portion 544, and a length of one side of an outer peripheral edge thereof is set to a value of substantially 1 to 3 mm.

[0135] In the present variation as well, the image-generating member 540 is configured such that, among light incident from the incident surface 542b of the lens portion 542 and reaching the emission surface 542a, light reaching the light-transmitting region 542aA is emitted as it is toward a front space of the lamp, while light reaching the light-shielding region 542aB is totally reflected (i.e. retroreflected) in a reverse direction toward the incident surface 542b by the plurality of corner cubes 550.

[0136] Note that, since the light-shielding region 542aB is set as a region larger than the external shape of the incident surface 542b of the lens portion 542, among light incident from the incident surface 542b of the lens portion 542 and reaching the emission surface 542a, all light other than light reaching the light-transmitting region 542aA is retroreflected.

[0137] Fig. 14 is a plan view illustrating a rendering light distribution pattern PD formed by light irradiated from the rendering lamp 510 according to the present variation.

[0138] The rendering light distribution pattern PD is formed as a light distribution pattern having a flat inverted V-shape (i.e., a shape slightly pointed toward the front of the lamp).

[0139] An image (i.e., an image serving as a basis for the rendering light distribution pattern PD) generated in the light-transmitting region 542aA of the emission surface 542a of the image-generating member 540 by light emitted from the light-emitting element 20 is formed in a flat V-shape, and the rendering light distribution pattern PD is formed as an inverted projected image of the image.

[0140] The rendering light distribution pattern PD is formed as a clear light distribution pattern, as in the present embodiment, since the light-transmitting region 542aA is positioned on the vertical plane passing through the rear focus F of the projection lens 30.

[0141] Even when the configuration of the present variation is adopted, utilization efficiency of light emitted from the light-emitting element 20 can be increased by a low-cost configuration, and the clear rendering light distribution pattern PD can be formed.

[0142] In the present variation as well, even when the light-emitting element 20 is configured as a white light emitting diode, it is possible to form the rendering light distribution pattern PD as a light distribution pattern having the same amber color as the light-emitting color of the front turn signal lamp 12.

[0143] In the present variation as well, the plurality of corner cubes 550 constituting the light-shielding region 542aB are formed to be recessed portions with respect to the front surface 544a of the flat plate portion 544. Additionally, the front surface 544a of the flat plate portion 544 is positioned on the vertical plane displaced toward the rear side of the lamp with respect to the light-transmitting region 542aA. As a result, the following effects can be obtained.

[0144] That is, in the image-generating member 540 as well, among light incident from the incident surface 542b of the lens portion 542 and reaching the emission surface 542a, light reaching the light-shielding region 542aB is retroreflected by the plurality of corner cubes 550.

[0145] Even if leakage light emitted toward the front of the lamp from boundary portions between the corner cubes 550 were to occur due to insufficient molding of the image-generating member 540 or the like, since the light-shielding region 542aB is displaced toward the rear side of the lamp with respect to the rear focal plane of the projection lens 30, it is possible to effectively suppress a situation in which mesh-like light non-uniformity inadvertently occurs, due to the leakage light emitted toward the front of the lamp through the projection lens 30, in a peripheral region of the rendering light distribution pattern PD on the road surface 2 ahead of the vehicle.

[0146] Next, a sixth variation of the above embodiment will be described.

[0147] Fig. 15 is a view similar to Fig. 4, illustrating an image-generating member 640 of a vehicle lamp 610 according to the present variation.

[0148] As illustrated in Fig. 15, a basic configuration of the image-generating member 640 of the present variation is similar to the image-generating member 540 of the fifth variation, but a configuration of a light-transmitting region 642aA of an emission surface 642a of a lens portion 642 is partially different from that of the fifth variation.

[0149] That is, the present variation is different from the fifth variation, in that the light-transmitting region 642aA is formed in a concave curved surface shape. Specifically, the light-transmitting region 642aA is constituted by a concave curved surface formed to make point contact, at the optical axis Ax, with a vertical plane passing through the rear focus F of the projection lens 30.

[0150] Therefore, in the image-generating member 640 of the present variation, light incident from an incident surface 642b of the lens portion 642 and reaching the light-transmitting region 642aA of the emission surface 642a is emitted into a front space of the lamp as light slightly diffusing around the optical axis Ax, and is then incident on the projection lens 30.

[0151] Note that, in the present variation as well, the light-transmitting region 642aA has the same external shape as that of the light-transmitting region 542aA of the fifth variation when viewed from the front of the lamp. In addition, a light-shielding region 642aB surrounding the light-transmitting region 642aA is constituted by a plurality of corner cubes 650 similar to the plurality of corner cubes 550 of the fifth variation.

[0152] Even when the configuration of the present variation is adopted, a rendering light distribution pattern similar to the rendering light distribution pattern PD formed in the fifth variation can be formed.

[0153] In the present variation, the light-transmitting region 642aA of the emission surface 642a of the image-generating member 640 is formed in a concave curved surface shape. As a result, an image serving as a basis for a rendering light distribution pattern can be formed as an image with less influence of field curvature, thereby making it possible to form the rendering light distribution pattern as a clearer light distribution pattern than the rendering light distribution pattern PD formed in the fifth variation.

[0154] Next, a seventh variation of the above embodiment will be described.

[0155] Fig. 16 is a view similar to Fig. 3, illustrating a vehicle lamp 710 according to the present variation.

[0156] As illustrated in Fig. 16, a basic configuration of the present variation is the same as that of the above embodiment, but a configuration of an image-generating member 740 and an arrangement of the light-emitting element 20 are different from those of the above embodiment. In addition, the present variation is different from the above embodiment in that a reflector 760 is arranged between the light-emitting element 20 and the image-generating member 740.

[0157] That is, the image-generating member 740 of the present variation is also constituted by a light-transmitting member (specifically, an amber-colored resin member), but a portion corresponding to the lens portion 42 of the image-generating member 40 of the above embodiment is constituted as a central flat plate portion 742 extending in a flat plate-like manner flush with a surrounding flat plate portion 744. In addition, the image-generating member 740 includes a horizontal surface portion 746 formed to extend in a flat plate-like manner along a horizontal plane from a lower end edge portion of the flat plate portion 744 toward the rear of the lamp.

[0158] In the image-generating member 740 of the present variation as well, a light-transmitting region 742aA and a light-shielding region 742aB similar to those of the image-generating member 40 of the above embodiment are formed on an emission surface 742a of the central flat plate portion 742.

[0159] In addition, in the present variation as well, the light-emitting element 20 is arranged on the rear side of the lamp of the image-generating member 740, but the light-emitting element 20 is mounted on a substrate 722 with the light emission surface 20a facing vertically upward. The substrate 722 is supported on an upper surface of the horizontal surface portion 746 of the image-generating member 740.

[0160] Additionally, in the present variation, a reflector 760 is arranged to cover the light-emitting element 20 from the upper side. The reflector 760 has a paraboloid-of-revolution-shaped reflecting surface 760a having a focus at a light emission center of the light-emitting element 20, and is configured such that light emitted from the light emission center of the light-emitting element 20 is reflected by the reflecting surface 760a as parallel light toward the frontward direction of the lamp. The reflector 760 is supported, at a flange portion 760b formed at a lower end portion thereof, on the upper surface of the horizontal surface portion 746 of the image-generating member 740.

[0161] The image-generating member 740 of the present variation is also configured such that, among light from the reflector 760 incident from the incident surface 742b of the central flat plate portion 742 and reaching the emission surface 742a, light reaching the light-transmitting region 742aA is emitted as it is toward a front space of the lamp, while light reaching the light-shielding region 742aB is totally reflected (i.e. retroreflected) in a reverse direction toward the incident surface 742b by a plurality of corner cubes 750.

[0162] Even when the configuration of the present variation is adopted, a rendering light distribution pattern similar to the rendering light distribution pattern PA formed in the above embodiment can be formed.

[0163] In the image-generating member 740 of the present variation, the plurality of corner cubes 750 constituting the light-transmitting region 742aA are formed on the emission surface 742a of the central flat plate portion 742 having a substantially constant thickness, and thus occurrence of sink marks during forming can be effectively suppressed, thereby increasing shape accuracy of each of the plurality of corner cubes 750.

[0164] In addition, the image-generating member 740 of the present variation has the horizontal surface portion 746 formed to extend in a flat plate-like manner along the horizontal plane from the lower end edge portion of the flat plate portion 744 toward the rear of the lamp. The substrate 722 on which the light-emitting element 20 is mounted and the reflector 760 are supported on the horizontal surface portion 746, and thus positional relationship accuracy among the light-emitting element 20, the reflector 760, and the light-transmitting region 742aA of the image-generating member 740 can be increased.

[0165] Note that the numerical values shown as specifications in the above embodiment and the variation are only examples and may be set to other values as appropriate.

[0166] In addition, the present disclosure is not limited to the configurations described in the above embodiment and the variation thereof, and configurations with various other modifications can also be adopted.
