Abstract

PROBLEM TO BE SOLVED: To obtain a small and color changeable lighting equipment which can change a light color quickly. SOLUTION: The color changeable lighting equipment is composed of light source (red R, green G, and blue B) in three primary colors, and optical elements 1, 2, 3 which consist of a mirror-cum-filter which are arranged on the same axle while countering aslant with each the light sources. Here, the optical element 3 of the front end side of irradiation is equipped with the characteristics that it penetrates colors G, R irradiated form the middle and the back end sides while reflecting the color B of the light source which counters this and the middle optical element 2 is equipped with the characteristics that it penetrates the color R irradiated from the back end side while reflecting the color G of the light source which counters this and the optical element 1 of the back end side is equipped with the characteristics of reflecting the color R of the light source which counters this. By these establishments, the color changeable light equipment can irradiate variable color lights to the front end side by changing the light intensity of each light source.
