PURPOSE: To irradiate a plane to be irradiated efficiently as maintaining the good view of the luminaire at night by installing a reflecting plate provided with a number of small holes between an upper shade and a lamp. CONSTITUTION: An upper shade 2 and a lower shade 3 are made of material with translucency, and a reflecting plate 4 provided with a number of small holes is installed between the shade 2 and the lamp 5. When the lamp 5 is turned on, the shade 3 is irradiated, and light passes through the plate 4 with a number of small holes to the shade 2 so as to irradiate the shade 2. Thereby, the good view of the luminaire is secured, and by finishing the inner face of the plate 4 into mirror-like, light distribution control downward can be performed so that a plane to be irradiated can be irradiated efficiently. Since the good view, of the luminaire is sufficient at a place where the good view including the luminaire is regarded important, and a street can be efficiently irradiated by the light, it is possible to improve the good view and to improve the safety of walking. |
