Abstract
In the development of the LED light sources that will be introduced here, the adopted color rendering evaluation indexes include Duv (Methods for determining distribution temperature and color temperature or correlated color temperature of light sources, JIS Z (8725–1999)), PS (Light 82–11:895–901, 1998), and FCI (Color Res Appl 32–5:361–371) in addition to the General Color Rendering Index (Ra) (Method of specifying color rendering properties of light sources, JIS Z (8726–1990)). The individual target values are defined to clarify the spectral radiation distribution. This article focuses on the above characteristics: the technical details used in the development of a LED light source called “Favorable Color (Bikou-shoku),” which preferably renders facial skin color, and “Vivid Color (Saikou-shoku),” which vividly renders the true colors of fresh food and plants.
