Benefits of technology

The present invention is an illumination system that has high flexibility and low cost. It includes a prism and a light uniforming device that can combine beams from multiple light sources. The system has a high number of light sources, making it flexible in design. The technical effects of the invention include high flexibility in light source design and low cost.

Problems solved by technology

Because the reflecting surfaces are located close to the converging points of the two beams where the temperature is high, reflecting films on the reflecting surfaces must be made of the material which resist high temperature, and thus the cost of the reflecting films is high.

Abstract

An illumination system including at least one first light source, a prism and a light uniforming device is provided. The first light source is capable of providing a first beam. The prism is disposed on a transmission path of the first beam, and has four first facets. Two of the first facets are opposite to each other, and the other two first facets are opposite to each other. The first beam passes through one of the first facets and is totally internally reflected by another first facet opposite to the one of the first facets. The light uniforming device is disposed on the transmission path of the first beam from the another first facet. The cost of the illumination system is lower, and the illumination system has high flexibility of the light source design and can provide illumination with high brightness.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an illumination system. More particularly, the present invention relates to an illumination system with beam combining function.[0003]2. Description of Related Art[0004]U.S. Pat. No. 5,765,934 has disclosed a light-refracting element applied in a light source in its first embodiment. The light source has a lamp for emitting a beam of luminous flux. The light-refracting element is disposed in the vicinity of the converging point of the beam of luminous flux, and takes the form of a cone. The flat surface of the light-refracting element facing the lamp. The beam of luminous flux is incident on the flat surface, and passes through and is refracted by the light-refracting element. Then, the beam of luminous flux exits from the conical surface of the light-refracting element. Through the refraction effect of the light-refracting element, the beam of luminous flux exiting from the light-refrac...
