Abstract:
A lighting device includes a polychromatic light source for emitting light in a plurality of colors, a light filter, and an optical element, wherein the light filter and the optical element are sequentially provided in an optical path of the polychromatic light source; a through hole is provided in the light filter, and the through hole has a size smaller than that of light spots of the polychromatic light source reaching the through hole; and the optical element is used for adjusting the light spots. Since the through hole has a size smaller than that of the light spots of the polychromatic light source reaching the through hole, the light filter can block stray light around the light spots such that more uniform portion of the light spots passes through the through hole, thereby improving the light-emitting effect of the lighting device.

Claim (Index 6):
The lighting device according to  claim 5 , wherein the lens is located between the light filter and the Fresnel lens.
