Abstract
A light source, including an excitation light source, an excited light supplying device, a partially coating film and a light supplementing device. The partially coating film is arranged on light path of the excitation light and the excited light, which includes a first area for transmitting/reflecting the excitation light to form main path light or side path light respectively, and a second region area for reflecting/transmitting all incident light; the excited light supplying device is provided on light path of the main path light to generate excited light transmitted to the partially coating film after irradiated by main path light; the light supplement device is provided on light path of the side path light for performing light homogenization on the side path light and generating supplemental light transmitted to the partially coating film; and the supplemental light combines with the excited light after passing through the partially coating film.
