Patent ID: 7182482

Claim:
A light device, comprising a panel bearing an array of light sources, or clusters of light sources, and an optical system for controlling the light beam at output from said light sources, wherein the optical system is set in front of each light source for controlling the radiation emitted by the light source, said optical system including an off-axis refractive lens or off-axis Fresnel lens having a first face, which is planar and is set facing the light source, and a second face, wherein said first face incorporates a diffuser of a refractive or diffractive micro-optical type, which covers at least part of the surface of said first face, and wherein set between the light source and the optical system is a system of diaphragms or a tubular element eqiuvalent thereto for absorption of the solar radiation that comes from outside and is transmitted by the optical system into said absorbent system.
