PURPOSE:To obtain a projecting light having a large light quantity adapted for a dielectric light source and a clear contour without using a lens with small number of components by condensing a light irradiated from a light emitting diode element via a light focusing hole of a reflecting surface by the inner surface to increase the quantity of the light, and converting it to a projecting light of a predetermined shape by a frame itself. CONSTITUTION:A case 13 is composed of a black (light absorbing color) member, and light focusing holes 14 are provided at positions corresponding to the positions of LED pellets 12 of the case 13. The pellet 12 is exposed externally from the bore side of the hole 14. The inner surface of each hole 14 is mirror-finished, and a reflecting surface 15 is formed on the same surface. A light X irradiated from the pellet 12 is propagated to an emitting port 14a while condensing, i.e., increasing in the light quality by the pyramidal shape of the hole 14 and the reflection of the surface 15. The light is converted to a predetermined shape, i.e., a square projecting light by the case itself (black) and externally irradiated. |
