Zusammenfassung:	PROBLEM TO BE SOLVED: To utilize a light source other than a fluorescent lamp, in a light box of a conventional technology. SOLUTION: The light source is composed of first and second constituent light sources, a mixing device, and a controller. The first constituent light source emits light having perceptive colors capable of changing in a given two-dimensional region of CIE 1976 color space in accordance with combinations of color control signals. The second constituent light source emits white-color light. The mixing device generates output light signals with perceptive output colors by combining light from the first and the second constituent light sources. The controller generates combinations of color control signals in accordance with input signals from one signal source outside the light sources, and maintains a perceptive output color at one point in the CIE 1976 color space decided by the input signals.
