摘要:
A lighting apparatus according to the present invention includes a light guiding unit and a plurality of light sources arranged along the incidence face of the light guiding unit. The plurality of light sources are constituted by a plurality of light source groups such that one light source group corresponds to one block. The one light source group includes a plurality of white light sources and a plurality of color light sources. Among the plurality of color light sources included in the one light source group, the color light sources with an emission color of the highest light intensity, when the light sources are driven under identical drive conditions, are disposed at both ends of the light source group. All of the white light sources included in the plurality of light sources arranged along the incidence face are disposed equidistantly.
