<P>PROBLEM TO BE SOLVED: To provide a luminaire using an LED as a light source and radiating light in a plurality of directions other than an LED radiating direction to adjust distributed light. <P>SOLUTION: A half reflection member 24 for transmitting part of incident light and reflecting other light toward another radiation opening 22 is provided in one radiation opening 21 of the pair of radiation openings 21, 22 and an LED light source part 30 is directed toward one radiation opening 21. Owing to the above, part of light radiated from the LED light source part 30 in one direction transmits through the half reflection member 24 and is radiated from one radiation opening 21 and light reflected from the half reflection member 24 is radiated from another radiation opening 22, by which light is radiated in the plurality of directions other than the radiating direction of the LED 32. <P>COPYRIGHT: (C)2010,JPO&INPIT |
