Abstract
A lighting system capable of adjusting color temperature is provided. The lighting system mainly comprises a light source module and a mixing assembly. The light source module produces red-color, blue-color, and green-color lights so as to control the color temperature of a white light resulted from mixing the color lights. The mixing assembly is located at a side of the light source module and comprises a first, a second, and a third mixing device sequentially arranged along the light transmission path. The function of the first and third mixing devices is for light mixing by causing the lights to undergo multiple internal reflections. The second mixing device directs the lights passing through the first mixing device in a reverse direction (180 degrees) and enters into the third mixing device.
