<P>PROBLEM TO BE SOLVED: To provide a lighting unit provided with a light source arrangement region formed by arranging a plurality of light sources, in which there is provided a lighting structure capable of improving uniformity of lighting luminance over an entire lighting range of the lighting unit, and suppressing a production cost and power consumption. <P>SOLUTION: The lighting unit 110 includes a light source arrangement region A where a plurality of light sources 112 are planarly arranged on a substrate 111 and a light diffusion plate 116 arranged at a front side of the light source arrangement region A. Therein, each of the light sources 112 has a light emitting distribution having a center in a direction of a normal line of an arrangement plane, and a reflecting slope 115a is provided which encloses the light source arrangement region A on the substrate 111, and which inclines outside from the normal line direction. <P>COPYRIGHT: (C)2009,JPO&INPIT |
