| titleOfInvention | Projection light source device |
| abstract | (57) [Summary] (Correction) [Purpose] To provide a light projecting light source device that eliminates the difference in brightness of the irradiation surface, improves the overall brightness, and improves the lamp life. A bulb 1 having a bulb 30 formed of a sphere or an ellipsoid, the surface of which is a light emitting surface, and a reflector 2 which accommodates the lamp 1 and reflects the light emitted from the lamp to the front surface are provided. A light diffusing surface 31 was formed on the inner surface of the. [Effect] Since the light diffusing surface is formed on the inner surface of the bulb, the entire surface of the bulb can be illuminated. Assuming that the light diffusing surface has the same area, compared to the case where the light diffusing surface is formed on the outer surface of the bulb. The area of the valve wall can be increased, and thus the tube wall load can be reduced. |
