Abstract
A light-projecting system includes a lamp module, a lens module and a uniform light module. The lamp module has a light source and a reflector for surrounding a part of the light source, wherein the light source is used to produce light signals, and the reflector is used to receive and reflect light signals. The lens module is arranged beside the lamp module for receiving light signals from the reflector and projecting light signals. The uniform light module is arranged beside the lens module for receiving light signals from the lens module and uniforming light signals. Moreover, because the lens module replaces the plane glass of the prior art and the lens module has a light filtering coating coated thereon, not only is the distance between the lamp module and the uniform light module shortened, but the light-projecting effect is also increased.
