ABSTRACT:
A light device has a plurality of light sources, and laser beam sources are arranged near a discharge bulb so that the laser beam can be overlapped with illuminating light from the discharge bulb. By doing so, the illuminating light is irradiated as overlapped illuminating light reinforcing red component, so that color rendering and luminance can be improved.
