<P>PROBLEM TO BE SOLVED: To provide a lighting system with optical members to control light distribution made thin and lightweight, even when a plurality of light sources are used. <P>SOLUTION: The lighting system L is provided with a plurality of light emission sections (LEDs 2) and the optical member 3. The optical member 3 has regions of refraction types 3b1R, 3b2R, 3b3R of Fresnel lenses 3b1, 3b2 and 3b3 individually formed, in correspondence to the light emission sections, and has regions of reflection types 3b1L, 3b2L, and 3b3L of the Fresnel lenses formed, between the regions of each refraction type. <P>COPYRIGHT: (C)2012,JPO&INPIT |
