PURPOSE:To enable an uniform light release with a proper brightness by reflecting the released lights from a number of light emitting diodes with a number of reflecting surfaces in the direction of light releasing windows. CONSTITUTION:A reflector 6 having a number of reflecting surfaces 61 for reflecting the released lights from a number of light emitting diodes 5 in the direction of light releasing windows 2, 3. In this case, each light emitting diode 5 is disposed inside the edge forming the light releasing windows 2, 3. Thus, most of the emitted lights from these light emitting diodes 5 are not released directly from the light releasing windows, but dispersed and reflected by the reflector 6 having many reflecting surfaces 61 and released. At a result, the light can be released fully from the light releasing windows 2, 3 and nearly uniformly by using the irreducible minimum number of light emitting diodes 5 from the view of lighting brightness. |
