The light emitter 3 is slightly larger than the ornament body 2. A tapered surface 30 is formed on the periphery of the light emitter 3. The tapered surface 30 is formed so as to narrow in the direction from the back to the front. The tapered surface 30 is inclined by θ = 45 ° with respect to the back-front direction. A reflective film 20 that reflects light is interposed between the back of the ornament body 2 and the surface of the light emitter 3. Specifically, the reflective film 20 is formed by printing a white paint on the surface of the light emitter 3.
[0024]
A front grille panel 9 made of resin and having a rectangular plate shape is disposed on the back side of the light emitter 3. The front grille panel 9 is included in the exterior member of the present invention. An elliptical through hole 90 is formed in the approximate center of the front grill panel 9. The diameter of the through hole 90 is set smaller than the diameter of the light emitter 3. The back surface of the light emitter 3 is fixed to the periphery of the through hole 90.
[0025]
The light source unit 4 includes an LED lamp portion 40, a front light guide 41, a back light guide 42, and a light source reflective film 43. The front light guide 41 is made of acrylic and has a rectangular plate shape. The surface of the front light guide 41 is smooth and is in contact with the back surface of the front grill panel 9. The back surface of the front light guide 41 has a wave shape. On the other hand, the back-side light guide 42 is made of acrylic and has a rectangular plate shape. The surface of the back side light guide 42 is wavy. And the surface of the back side light guide 42 is joined to the back surface of the front side light guide 41 in a wave shape. The back surface of the back side light guide 42 is smooth. The light source reflective film 43 is formed by depositing silver on the back surface of the back light guide 42. A total of two LED lamp portions 40 are arranged on both sides of the front light guide 41 and the back light guide 42. The LED lamp unit 40 is electrically connected to a battery (not shown).
[0026]
The bracket 5 is made of resin and has a shallow tray shape. The light source unit 4 is accommodated inside the tray of the bracket 5. A mounting seat 50 is disposed on each of the upper and lower edges of the bracket 5. A bracket side mounting hole 51 is formed in the mounting seat 50. A panel-side mounting hole 91 is formed on the rear surface of the front grill panel 9 so as to communicate with the bracket-side mounting hole 51. The light source unit 4 is fixed by the screw 52 passing through the bracket side mounting hole 51 and being fixed to the panel side mounting hole 91.

Next, the effect of the light emission ornament of the reference form will be described. In the case of the light emitting ornament 100 shown in FIG. 6, only one LED lamp 103 is disposed adjacent to one side of the light emitter 102. Further, the light emitter 102 (corresponding to the front-side light guide 41 and the back-side light guide 42 in the reference form) itself did not have any device for making the light emission uniform. For this reason, the part close to the LED lamp 103 was bright, and the part away from the LED lamp 103 was dark. That is, the brightness was uneven. On the other hand, the light source unit 4 of the light emitting ornament 1 of the reference form emits light almost uniformly. In addition, the light source unit 4 is disposed on the back side of the light emitter 3. For this reason, there is little risk of unevenness in the brightness of the light emitter 3.
[0029]
Moreover, the periphery of the light-emitting body 3 of the light-emitting ornament 1 of the reference form is exposed. For this reason, not only the surface of the light emitter 3 but also the periphery emits light.

Furthermore, the periphery of the light emitter 3 is set to be larger than the periphery of the ornament body 2, and a tapered surface 30 is disposed on the periphery of the light emitter 3. Therefore, the light at the periphery of the light emitter 3 is likely to be emitted in the surface direction of the light emitter 3 through the tapered surface 30. That is, it becomes easy to visually recognize the periphery of the light emitter 3 from the surface of the light emitter 3. In this respect as well, the ornament body 2 can be displayed more prominently.
[0031]
Further, the tapered surface 30 is inclined by θ = 45 ° with respect to the front-back direction. For this reason, the light emitted from the light emitter 3 is less likely to diffuse more laterally than the surface of the light emitter 3. Further, when viewed from the surface of the light emitter 3, the risk that the periphery of the light emitter 3 becomes dark is small. That is, the light-emitting ornament 1 of the reference form is excellent in design, particularly when viewed from the surface of the light-emitting body 3.
[0032]
A reflective film 20 that reflects light is interposed between the back of the ornament body 2 and the surface of the light emitter 3. For this reason, according to the light emission ornament 1 of the reference form, the light propagating through the light emitter 3 is reflected by the reflection film 20. Therefore, it becomes difficult for light to attenuate. For this reason, the periphery of the light emitter 3 becomes brighter.
[0033]
Further, according to the light source unit 4 of the light emitting ornament 1 of the reference form, the LED lamp portions 40 are disposed on both sides of the front light guide 41 and the back light guide 42. Therefore, compared with the case where it arrange | positions on the back side of the back side light guide 42, the thickness of the front and back direction is thin, and it is excellent in space-saving property.
[0034]
Moreover, according to the light emission ornament 1 of the reference form, when the LED lamp unit 40 is turned off, the silver light source reflection film 43 is visually recognized from the outside through the light emitter 3, the front light guide 41, and the back light guide 42.
