Abstract
A lighting device configured to produce light in a substantially uniform overall color includes a plurality of light source boards and a plurality of point light sources. The point light sources are mounted on the light source boards. An average color of the point light sources is in an equivalent color range. The equivalent color range is defined by a square with two sides that are opposed sides each having an X-axis coordinate length of 0.015 and two sides that are opposed sides each having a Y-axis coordinate length of 0.015 in the CIE 1931 color space chromaticity diagram.
