Description

[Technical field]

[0001] The present invention relates to a luminous emblem. [Background technology]

[0002] Patent Document 1 describes an emblem light-emitting device. This light-emitting device includes a housing and an outer lens that covers the opening of the housing. In addition, the space surrounded by the housing and the outer lens contains a diffusing material, a board on which a light source is mounted, an inner lens, and a reflecting material. An emblem is attached to the surface of the outer lens.

[0003] In such an emblem light-emitting device, light from a light source is irradiated toward the emblem via an inner lens, a diffusing material, and an outer lens, causing the periphery of the emblem to emit light. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2014-141197 A Summary of the Invention [Problem to be solved by the invention]

[0005] In conventional light-emitting emblems that include such light-emitting devices, the outer lens is fixed to the housing to seal the space surrounded by the outer lens and the housing from the viewpoint of waterproofing. However, in this case, it is difficult to replace only the light source when a problem occurs with the light source.

[0006] An object of the present invention is to provide an illuminating emblem that maintains waterproof performance while allowing the light source to be easily replaced. [Means for solving the problem]

[0007] Various aspects of the luminous emblem for solving the above problems will be described below. [Aspect 1] An illuminating emblem comprising a light source, a housing having an opening facing outward from a vehicle, and a transparent portion having visible light transmittance and a cover covering the opening, the illuminating emblem providing an illuminating display facing outward from the vehicle by transmitting light from the light source through the transparent portion, the housing having a through hole that penetrates a wall portion of the housing and into which the light source can be removably attached, and when the light source is attached to the through hole, the light source, the housing, and the cover form an enclosed space that is sealed from the outside.

[0008] According to the above configuration, the light source can be removed from the through-hole of the housing. Also, by reattaching the light source to the through-hole and transmitting light from the light source through the transmission portion, it is possible to perform light-emitting display toward the outside of the vehicle. Here, if the light source is simply attached to the through-hole, there is a risk that water droplets will enter the inside of the housing through a gap that occurs between the part of the wall of the housing that constitutes the through-hole and the light source. In this regard, according to the above configuration, when the light source is attached to the through-hole, a sealed space that is sealed from the outside is formed by the light source, the housing, and the cover. Therefore, the intrusion of water droplets into the housing is suppressed. Therefore, the light source can be easily replaced while maintaining water-stopping performance.

[0009] [Aspect 2] An illuminating emblem as described in [Aspect 1], in which a reflective member is provided between the cover and the housing, covering the light source from the front in the emission direction of the light from the light source and reflecting the light, and the reflective member is provided with a convex portion at a position facing the light source in the emission direction, which protrudes toward the light source and has an inclined surface inclined with respect to the optical axis of the light source, and the inner surface of the housing is configured to reflect the light toward the cover.

[0010] When the light source is not lit, it may be visible from outside the vehicle through the transparent portion. In this case, the appearance of the luminous emblem is degraded. In this regard, according to the above configuration, the light source is covered by a reflective member from the front. This makes it difficult for the light source to be visible through the transparent portion from outside the vehicle. Therefore, it is possible to prevent the appearance of the luminous emblem from being degraded.

[0011] On the other hand, when a member that covers the light source is simply provided from the front in the emission direction, the light from the light source is blocked by the member, which causes a problem that it is difficult to efficiently transmit the light through the transmission part. In this regard, according to the above configuration, the light emitted from the light source is reflected by the reflection member. Here, the reflection member is provided with a convex portion having an inclined surface at a position facing the light source in the emission direction. Therefore, the light is reflected by the inclined surface and diffused to the outer periphery side of the convex portion with the convex portion as the center. Then, the diffused light is reflected toward the cover after being reflected one or more times between the inner surface of the housing and the reflection member. The light thus incident on the cover is irradiated toward the outside of the vehicle by transmitting through the transmission part. That is, light is emitted toward the outside of the vehicle. Therefore, even when a member that covers the light source is provided from the front in the emission direction, the light from the light source can be efficiently transmitted through the transmission part.

[0012] [Aspect 3] The reflective member is provided on the outer periphery of the convex portion and comprises a protrusion having an opposing surface facing the inclined surface in a direction perpendicular to the axial direction of the optical axis, and a hole portion provided between the convex portion and the protrusion portion, and is configured to reflect the light reflected by the inclined surface and incident on the opposing surface of the protrusion portion through the hole portion toward the transparent portion. [Aspect 2].

[0013] According to the above-mentioned configuration, a part of the light reflected by the inclined surface of the convex portion is incident on the opposing surface of the protrusion. The light incident on the opposing surface is reflected toward the transmission portion through the hole. Therefore, the light from the light source can be transmitted to the transmission portion more efficiently.

[0014] [Aspect 4] The luminous emblem described in [Aspect 3], wherein the transparent portion is provided at the center and outer edge of the cover, the wall portion comprises a bottom wall having the through hole, a side wall constituting the opening, and a connecting wall connecting the bottom wall and the side wall, a connecting surface of the inner surface constituting the connecting wall is inclined with respect to the optical axis, the reflective member is configured to reflect the light reflected by the inclined surface and incident on the opposing surface of the protrusion through the hole toward the transparent portion of the center, and the housing is configured to reflect the light reflected by the inclined surface and incident on the connecting surface toward the transparent portion of the outer edge.

[0015] According to the above configuration, a portion of the light reflected by the inclined surface of the convex portion is incident on the opposing surface of the protrusion. The light incident on the opposing surface is reflected through the hole toward the transmitting portion provided in the center of the cover. In addition, a portion of the light reflected by the inclined surface of the convex portion is incident on the connecting surface of the housing. The light incident on the connecting surface is reflected toward the transmitting portion provided on the outer edge of the cover. Therefore, the light from the light source can be uniformly transmitted through the transmitting portion of the cover.

[0016] [Aspect 5] An illuminating emblem described in any one of [Aspect 2] to [Aspect 4], wherein the reflective member and the housing are white to reflect the light. According to the above-mentioned configuration, the reflection efficiency of the light from the light source can be increased in the reflective member and the housing, so that the light from the light source can be transmitted to the transmission portion more efficiently. Effect of the Invention

[0017] According to the present invention, the light source can be easily replaced while maintaining waterproof performance. [Brief description of the drawings]

[Diagram 5] FIG. 5 is a cross-sectional view showing a lighting state of the light source unit of the light-emitting emblem of FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, one embodiment of the light emitting emblem 13 will be described with reference to FIGS. In the following description, the front and rear of the vehicle 10 in the longitudinal direction L where the light-emitting emblem 13 is provided will be simply referred to as the front and rear, respectively. Also, the upper and lower of the vehicle 10 in the vertical direction Z will be simply referred to as the upper and lower, respectively.

[0020] 1 and 2, a window portion 12 that opens forward is provided in an exterior panel 11 that constitutes a front portion 10a of a vehicle 10. A light-emitting emblem 13 is attached to the window portion 12.

[0021] The luminous emblem 13 emits light to display in the front of the vehicle 10, that is, toward the outside of the vehicle 10, and includes a light source unit 20, a housing 30, a cover 40, and a reflective member 50.

[0022] Each component will be described in detail below. <Light source unit 20> 1 and 2, the light source unit 20 has a case 21, a heat dissipation section 25, and a sealing member 26. The light source unit 20 in this embodiment corresponds to the light source according to the present invention.

[0023] The case 21 has a disk-shaped base portion 22 and a cylindrical wall portion 23 that protrudes forward from the base portion 22. A circuit board on which one or a plurality of light emitting elements (all not shown) are mounted is housed inside the cylindrical wall portion 23. As the light emitting element, for example, a light emitting diode (LED) can be used.

[0024] A plurality of claws 24 are provided on the outer circumferential surface 23a of the cylindrical wall portion 23. The plurality of claws 24 are arranged at intervals from one another over the entire circumference of the outer circumferential surface 23a. Heat dissipation section 25 dissipates heat generated by the light emitting element to the outside, and is connected to the rear end of case 21 by screws or the like. Heat dissipation section 25 is thermally connected to the circuit board, but is electrically insulated.

[0025] The seal member 26 is formed in an annular shape from an elastic material such as rubber, and is attached to the outer circumferential surface 23a of the cylindrical wall portion 23. The seal member 26 is disposed between the base portion 22 and the multiple claw portions 24 so as to abut against the base portion 22.

[0026] <Housing 30> As shown in FIGS. 1 and 2, the housing 30 has an opening 31 that opens toward the front of the vehicle 10, that is, toward the outside, and a wall portion 30A that forms the opening 31.

[0027] The wall 30A is made of a resin material in which white light diffusing particles are dispersed, and is white overall. As the resin material, for example, acrylonitrile-butadiene-styrene copolymer (ABS) resin can be used. As the light diffusing material, for example, metal oxides such as titanium oxide and zinc oxide can be used.

[0028] An inner surface 30a of the wall portion 30A forms a reflective surface that reflects visible light (hereinafter simply referred to as light). The wall portion 30A has a bottom wall 32 facing the opening 31 in the front-rear direction L, a side wall that constitutes the opening 31, and a connecting wall 33 that connects the bottom wall 32 and the side wall .

[0029] The bottom wall 32 is in the shape of a disk centered on an axis A extending in the front-rear direction L. The bottom wall 32 has a through hole 35 in the center thereof, into which the light source unit 20 is detachably attached.

[0030] The through hole 35 penetrates the bottom wall 32 in the front-rear direction L. The through hole 35 extends along an imaginary circle C centered on the axis A, and has a plurality of restricting edges 35a that restrict the insertion and removal of the claw portion 24 of the light source unit 20, and a plurality of notches 35b that allow the insertion and removal of the claw portion 24.

[0031] The case 21 and the through hole 35 are configured to allow the case 21 to be inserted into and removed from the through hole 35 by the claw portion 24 and the notch 35b when the light source unit 20 is in a first position shown in Fig. 2 relative to the through hole 35. On the other hand, the case 21 and the through hole 35 are configured to prevent the case 21 from being inserted into and removed from the through hole 35 by the claw portion 24 and the restricting edge portion 35a when the light source unit 20 is in a second position (see Fig. 3) rotated a predetermined angle from the first position about the axis A. When the light source unit 20 is in the second position, the restricting edge portion 35a and the claw portion 24 are positioned to overlap each other in the front-rear direction L.

[0032] 3, the light source unit 20 is attached to the through hole 35 so as to emit light toward the front of the vehicle 10. At this time, the optical axis of the light source unit 20 coincides with the axis line A. As described above, since the light source unit 20 emits light toward the front of the vehicle 10, the emission direction of light from the light source unit 20 is a direction from the rear to the front of the vehicle 10. The front in the light emission direction coincides with the front of the vehicle 10, and the rear in the light emission direction coincides with the rear of the vehicle 10.

[0033] With the light source unit 20 attached to the through hole 35, the seal member 26 is pressed against the portion of the bottom wall 32 that constitutes the through hole 35. The seal member 26 is pressed against both the above-mentioned portion and the base portion 22, thereby sealing the gap between the through hole 35 and the case 21 of the light source unit 20.

[0034] 2 and 3, the connecting wall 33 rises forward from the outer circumferential edge of the bottom wall 32 and extends at an incline with respect to the axis A. Accordingly, a connecting surface 33a constituting the connecting wall 33 on the inner surface 30a is also inclined with respect to the axis A. More specifically, the connecting surface 33a is inclined so as to approach the outer circumferential side as it extends forward in the front-to-rear direction L.

[0035] The connecting wall 33 is configured to reflect light incident on the connecting surface 33a forward (see FIG. 5). The side wall 34 is bent and extends forward from the connecting wall 33. The opening 31 is defined by a front end 34a of the side wall 34.

[0036] <Cover 40> 2 to 4, the cover 40 has a circular shape in a plan view, and is welded to the front end 34a of the side wall 34. The cover 40 is welded to the front end 34a over the entire circumference. That is, the opening 31 of the housing 30 is closed from the front by the cover 40. Note that as a welding method, for example, ultrasonic welding, laser welding, hot plate welding, etc. can be used.

[0037] When the light source unit 20 is attached to the through-hole 35, the light source unit 20, the housing 30, and the cover 40 form a sealed space S that is sealed from the outside (see FIG. 3).

[0038] The cover 40 has an inner portion 41 and an outer portion 44 located in front of the inner portion 41 . The inner part 41 is a so-called outer lens, and is made of a transparent material that transmits visible light. As the transparent material, for example, a transparent resin such as an acrylic resin such as polymethylmethacrylate resin (PMMA) or a polycarbonate (PC) resin can be used. Note that "transparent" in this embodiment includes colorless transparency as well as colored transparency (colored transparency).

[0039] A first exposed portion 42 and a second exposed portion 43 are integrally formed on the front surface 41a of the inner portion 41 as convex portions that protrude forward. The second exposed portion 43 is formed on the outer edge portion of the inner portion 41, i.e., the outer edge portion of the cover 40, in a portion located in front of the connecting surface 33a of the connecting wall 33. The first exposed portion 42 is formed in the center portion of the inner portion 41, i.e., the center portion of the cover 40. Here, the center portion of the cover 40 in this embodiment refers to a portion of the cover 40 that is located closer to the axis A side than the second exposed portion 43.

[0040] The outer portion 44 has a light-shielding portion 45 that blocks light, and a transparent portion 46 that is surrounded by the light-shielding portion 45 and has visible light transparency. In this embodiment, the portion of the outer portion 44 other than the transparent portion 46 is configured by the light-shielding portion 45.

[0041] The central portion 45a of the light shielding portion 45 is formed of a mixed material obtained by mixing a resin material such as PC resin with a black pigment such as carbon black. The outer edge portion 45b of the light shielding portion 45 is formed by applying a light-shielding coating or plating to the surface of a base material made of a resin material such as PC resin or ABS resin. The outer edge portion 45b covers the welded portion between the front end 34a of the side wall 34 and the inner portion 41 from the front.

[0042] The transmission portion 46 is a communication hole that connects the inside and outside of the outer portion 44 . The transparent portion 46 exposes the first exposed portion 42 toward the front of the vehicle 10 at the center of the cover 40. The transparent portion 46 also exposes the second exposed portion 43 toward the front of the vehicle 10 at the outer edge of the cover 40. The design surface 13a of the luminous emblem 13 is formed by the first exposed portion 42 and the second exposed portion 43 exposed forward by the transparent portion 46, and the light-shielding portion 45.

[0043] As shown in FIG. 4, the first exposed portion 42 and the second exposed portion 43 correspond to the pattern area 14 of the design surface 13a that displays a pattern such as a logo toward the front of the vehicle 10. More specifically, the first exposed portion 42 corresponds to the central portion 14a of the pattern area 14 that displays letters, symbols, etc. The second exposed portion 43 corresponds to the outer edge portion 14b of the pattern area 14 that extends in a ring shape along the outer edge of the cover 40. The light-shielding portion 45 corresponds to the background area 15 of the design surface 13a other than the pattern area 14. The light-emitting emblem 13 is configured so that the pattern area 14 can be seen from the front when the light source unit 20 is not lit.

[0044] <Reflective member 50> 2 and 3, the reflection member 50 has a disk shape in a plan view, and is provided between the cover 40 and the housing 30. The reflection member 50 covers the light source unit 20 from the front when the light source unit 20 is attached to the through-hole 35.

[0045] The reflective member 50 is made of a resin material in which white light diffusing particles are dispersed, and is white overall. The resin material may be, for example, ABS resin. The light diffusing material may be, for example, a metal oxide such as titanium oxide or zinc oxide.

[0046] The reflecting member 50 is integrally formed with a protrusion 51 and an extension 53 extending from the protrusion 51 to the outer periphery. The protrusion 51 has a cone shape centered on the axis A, and protrudes toward the light source unit 20 when the light source unit 20 is attached to the through hole 35. That is, the protrusion 51 faces the light source unit 20 in the front-rear direction L.

[0047] The protrusion 51 has an inclined surface 52 that is inclined with respect to the axis A. The extending portion 53 is integrally formed with a protruding portion 54 that protrudes rearward and a hole portion 55 that penetrates the extending portion 53 .

[0048] In this embodiment, the protrusion 54 is provided below the convex portion 51 in the up-down direction Z. The protrusion 54 has an opposing surface 54a that faces the inclined surface 52 in the up-down direction Z among orthogonal directions perpendicular to the front-rear direction L. The opposing surface 54a is inclined so as to approach the convex portion 51 in the up-down direction Z as it moves toward the rear. Note that the up-down direction Z in this embodiment corresponds to the orthogonal direction perpendicular to the axial direction of the optical axis according to the present invention.

[0049] The hole 55 is located between the convex portion 51 and the protruding portion 54 in the vertical direction Z. The protruding portion 54 extends in a bent state from the edge of the extending portion 53 that constitutes the hole 55. As shown in FIG. 5, the reflective member 50 is configured to reflect light that is reflected by the inclined surface 52 and enters the opposing surface 54a of the protrusion 54 through the hole 55 toward the first exposed portion 42 and the transmissive portion 46.

[0050] Next, the operation of this embodiment will be described. 2, in order to assemble the light source unit 20 to the housing 30, the worker inserts the case 21 of the light source unit 20 from the rear in a first position posture with respect to the through hole 35. At this time, the notch 35b allows the claw portion 24 to pass through. This allows the case 21 to pass through the through hole 35.

[0051] 3, as the case 21 is inserted further into the through-hole 35, the sealing member 26 is elastically deformed by being pressed against both the portion of the bottom wall 32 that constitutes the through-hole 35 and the base portion 22. This creates a seal between the through-hole 35 and the case 21 of the light source unit 20.

[0052] Thereafter, the light source unit 20 is rotated from the first position shown in Fig. 2 to a second position (see Fig. 3) rotated a predetermined angle around the axis A. At this time, the restricting edge 35a and the claw portion 24 are in a position where they overlap with each other in the front-rear direction L. Therefore, the restricting edge 35a and the claw portion 24 prevent the case 21 from coming out rearward from the through hole 35. As a result, the light source unit 20 is assembled to the housing 30 with the gap between the through hole 35 and the light source unit 20 sealed (this is operation 1).

[0053] Furthermore, when it becomes necessary to replace the light source unit 20 due to a malfunction of the light emitting element or the circuit board on which the light emitting element is mounted, the worker performs the reverse operation of the above-mentioned operation 1. As a result, the light source unit 20 is removed from the through hole 35 of the housing 30.

[0054] Next, the effects of this embodiment will be described. (1) The housing 30 has a through-hole 35 that penetrates the wall portion 30A and to which the light source unit 20 is detachably attached. When the light source unit 20 is attached to the through-hole 35, a sealed space S that is sealed from the outside is formed by the light source unit 20, the housing 30, and the cover 40.

[0055] This configuration provides the above-mentioned effects. Therefore, the light source unit 20 can be removed from the through-hole 35 of the housing 30. In addition, by reattaching the light source unit 20 to the through-hole 35 and transmitting light from the light source unit 20 through the transmitting portion 46, the pattern area 14 can be illuminated and displayed forward of the vehicle 10.

[0056] Here, if the light source unit 20 is simply attached to the through hole 35, there is a risk that water droplets will enter the inside of the housing 30 from a gap that occurs between the light source unit 20 and a portion of the wall portion 30A of the housing 30 that constitutes the through hole 35. In this regard, according to the above configuration, when the light source unit 20 is attached to the through hole 35, a sealed space S that is sealed from the outside is formed by the light source unit 20, the housing 30, and the cover 40. Therefore, the intrusion of water droplets into the housing 30 is suppressed. Therefore, the light source unit 20 can be easily replaced while maintaining waterproof performance.

[0057] (2) Between the cover 40 and the housing 30, a reflective member 50 is provided which covers the light source unit 20 from the front and reflects light. When the light source unit 20 is not lit, the light source unit 20 may be visible from the front of the vehicle 10 through the transparent portion 46. In this case, the appearance of the luminous emblem 13 is degraded. In this regard, according to the above configuration, the light source unit 20 is covered by the reflective member 50 from the front. This makes it difficult for the light source unit 20 to be visible through the transparent portion 46 from the front of the vehicle 10. Therefore, it is possible to prevent the appearance of the luminous emblem 13 from being degraded.

[0058] (3) The reflective member 50 is provided with a convex portion 51 at a position facing the light source unit 20 in the front-rear direction L, the convex portion 51 protruding toward the light source unit 20 and having an inclined surface 52 inclined with respect to the axis A. The inner surface 30a of the housing 30 is configured to reflect light toward the cover 40.

[0059] If a member that covers the light source unit 20 is simply provided from the front, the light from the light source unit 20 is blocked by the member, and this causes a problem that it is difficult to efficiently transmit the light to the transmission portion 46. In this regard, according to the above configuration, as shown in FIG. 5, the light emitted from the light source unit 20 is reflected by the reflection member 50. Here, the reflection member 50 is provided with a convex portion 51 having an inclined surface 52 at a position facing the light source unit 20 in the front-rear direction L. Therefore, the light is reflected by the inclined surface 52 and diffused to the outer periphery side of the convex portion 51 with the convex portion 51 as the center. Then, the diffused light is reflected toward the cover 40 after being reflected once or multiple times between the inner surface 30a of the housing 30 and the reflection member 50. The light thus incident on the cover 40 is irradiated toward the front of the vehicle 10 by transmitting through the transmission portion 46. That is, the pattern area 14 is illuminated toward the front of the vehicle 10. Therefore, even if a member that covers the light source unit 20 from the front is provided, the light from the light source unit 20 can be efficiently transmitted through the transmission portion 46 .

[0060] (4) The reflective member 50 includes a protrusion 54 provided on the outer circumferential side of the convex portion 51 and having an opposing surface 54a facing the inclined surface 52 in the vertical direction Z, and a hole portion 55 provided between the convex portion 51 and the protrusion 54.

[0061] According to this configuration, a part of the light reflected by the inclined surface 52 of the convex portion 51 is incident on the opposing surface 54a of the protrusion 54. The light incident on the opposing surface 54a is reflected toward the transmission portion 46 through the hole 55. Therefore, the light from the light source unit 20 can be transmitted to the transmission portion 46 more efficiently.

[0062] (5) The transmitting portion 46 is provided in the center and the outer edge of the cover 40. The wall portion 30A includes a bottom wall 32 having a through hole 35, a side wall 34 forming the opening 31, and a connecting wall 33 connecting the bottom wall 32 and the side wall 34. The connecting surface 33a is inclined with respect to the axis A. The reflecting member 50 is configured to reflect light reflected by the inclined surface 52 and incident on the opposing surface 54a of the protruding portion 54 toward the transmitting portion 46 in the center through the hole portion 55. The housing 30 is configured to reflect light reflected by the inclined surface 52 and incident on the connecting surface 33a toward the transmitting portion 46 in the outer edge.

[0063] According to this configuration, as shown in FIG. 5, a part of the light reflected by the inclined surface 52 of the convex portion 51 is incident on the opposing surface 54a of the protrusion 54. The light incident on the opposing surface 54a is reflected toward the transmission portion 46 provided in the center of the cover 40 through the hole portion 55. In addition, a part of the light reflected by the inclined surface 52 of the convex portion 51 is incident on the connecting surface 33a of the housing 30. The light incident on the connecting surface 33a is reflected toward the front of the connecting surface 33a, that is, toward the transmission portion 46 provided on the outer edge portion of the cover 40. The light reflected toward the transmission portion 46 of the cover 40 in this manner is irradiated toward the front of the vehicle 10 by uniformly transmitting the transmission portion 46 via the first exposed portion 42 and the second exposed portion 43. Therefore, the light from the light source unit 20 can be uniformly transmitted through the transmission portion 46 of the cover 40.

[0064] (6) The reflective member 50 and the housing 30 are white in color to reflect light. According to this configuration, it is possible to increase the reflection efficiency of the light from the light source unit 20 in the reflective member 50 and the housing 30. Therefore, it is possible to transmit the light from the light source unit 20 to the transmission portion 46 more efficiently.

[0065] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.

[0066] The reflective member 50 is not limited to being made of a resin material in which white light diffusing particles are dispersed, as exemplified in this embodiment. The reflective member 50 may be formed, for example, by applying a coating film in which white light diffusing particles are dispersed to the surface of a base material made of a resin material.

[0067] The reflecting member 50 is not limited to being made of a resin material, and may be made of a metal material. The housing 30 is not limited to being made of a resin material in which white light diffusing particles are dispersed, as exemplified in this embodiment. For example, the housing 30 may be formed by applying a coating film in which white light diffusing particles are dispersed to the inner surface of a wall portion formed of a resin material.

[0068] The housing 30 and the reflective member 50 do not have to be white. The light-shielding portion 45 may be entirely made of a mixed material of a resin material such as PC resin and a black pigment such as carbon black, or may be formed by applying a light-shielding coating or plating to the surface of a base material entirely made of a resin material such as PC resin or ABS resin.

[0069] The connecting surface 33a is not limited to being inclined with respect to the axis A, but may be, for example, a concave surface curved with respect to the axis A. The protrusion 54 and the hole 55 are not limited to being provided below the convex portion 51 in the up-down direction Z as exemplified in this embodiment, and their arrangements may be changed as appropriate. Even in this case, it is sufficient that the light incident on the facing surface 54a is reflected through the hole 55 toward the first exposed portion 42 and the transmitting portion 46.

[0070] The protrusions 54 and the holes 55 may be omitted from the reflecting member 50. The through-hole 35 is not limited to being provided in the center of the bottom wall 32 as exemplified in this embodiment, and the arrangement may be changed as appropriate. The number of through-holes 35 is also not limited to one, and a plurality of through-holes may be provided according to the number of light source units 20 mounted on the light-emitting emblem 13. In either case, it is sufficient to provide a protrusion 51 at a position on the reflective member 50 facing the light source unit 20 in the front-rear direction L. [Explanation of symbols]
