摘要：<P>PROBLEM TO BE SOLVED: To enlarge the feedback periods based on the properties of the light emitting sources to simplify the system and to save the costs by controlling colors by using only a single simple feedback system. <P>SOLUTION: This lighting system has a three primary-color light emitting source 23 consisting of a red, green, and blue light emitting diodes 23R, 23G, and B, a back light unit 26 to output white light by mixing the light from the above light emitting source 23, a light quantity detector 32 to obtain the amount of each color light from the above light emitting source 23, and a controller 33 to control the light quantity balance of the color light from the light emitting source 23 based on the outputs of the light quantity detector 32. <P>COPYRIGHT: (C)2008,JPO&INPIT
