PURPOSE:To increase light condensing efficiency by arranging a device to reflect the light, which is emitted from a light source and advances directly forward without proceeding in the reflector direction, in the reflector direction. CONSTITUTION:A reflecting mirror 1 is installed in a sealing part 3. The light, which is emitted from an emission tube 2 and advances forward, is reflected by means of the reflecting mirror 1, and proceeds in the reflector 4 direction. The light is reflected by means of the reflector 4, and is emitted forward while growing into approximately parallel beams. |
