<P>PROBLEM TO BE SOLVED: To provide a lighting system in which surface light emission can be carried out from a light-emitting surface without using a light guide plate even when the lighting system has an illumination structure in which a directional light source is arranged at an end part of the light-emitting surface and is used as a light source, and which can radiate white light with a high color rendering property as irradiation light. <P>SOLUTION: A light diffusion film 22 having both light diffusion function and reflection function is attached on the rear surface of a lens 13. A reflecting plate 21 is mounted in a position opposite to the light diffusion film 22 with a gap formed with the film 22. Commercially-available white LEDs and red-green LEDs are alternately arranged as an LED 17 on both sides of a body case 5 in the width direction. The irradiation light of the LED 17 is reflected at the light diffusion film and reflecting plate 21 each other and is guided in the irradiation direction, and is diffused in the orthogonal direction vertical to the irradiation direction of light by a diffusion effect of the light diffusion film 22, and is surface-emitted from the lens 13. <P>COPYRIGHT: (C)2011,JPO&INPIT |
