Abstract

This invention presents a projection system of LED lamps, which is composed of a plurality of reflection LED light sources, where the emitting surface of the LED light sources for the LED spot sources is turned upward, a foundation is set in the horizontal plane, whereas the foundation forms a semi-reflector with continuous multi-surfaces in its inner surface, such that the LED light, which is emitted in the upward direction, is reflected to emit out in the ahead direction. As a result, the projection system of LED lamps only needs a semi-reflector, the LED lights can be fully emitted out in the forward direction to obtain the small-sized advantage compared to the reflection lamp.
