<P>PROBLEM TO BE SOLVED: To solve a problem that, in a lighting system, a lens is used in order to obtain planar and uniform light distribution, while reducing the number of LED elements, however, in this case, loss of light is generated and a supporting structure of the lens becomes complicated. <P>SOLUTION: The planar lighting system 10 having a substrate 16 and a scattering plate 14 is provided with a light-emitting unit 11 arranged on the substrate 16. The light-emitting unit 11 includes a support body 12 having a plurality of slant faces on the scattering plate 14 side and LED elements 15 are installed on the slanted face of the support body 12. Thereby, the lighting system 10 can have a structure in which planar and almost uniform light distribution is obtained yet, loss of light is reduced. <P>COPYRIGHT: (C)2012,JPO&INPIT |
