<P>PROBLEM TO BE SOLVED: To provide an LED luminaire capable of making thinner than existing one. <P>SOLUTION: A lens part 55 comprising an aspherical lens formed by combining a spherical concave lens 55b in the central part of a spherical planoconvex lens 55a is installed in a position facing each light emitting diode 3 in a front wall part 50 of a housing 5. An irradiation range of light at the same distance is widened than an exiting type in which the lens part 55 is made with a condenser lens. As a result, the distance between the front wall part 50 of the housing 5 and an irradiation object, for example, that to a plane panel (a diffusion panel) dispersing light of the light emitting diode 3 arranged in the front of the front wall part 50 can be shortened, and the thickness of the LED luminaire including the irradiating object (the diffusion panel or the like) can relatively be reduced to make the luminaire thin. <P>COPYRIGHT: (C)2007,JPO&INPIT |
