Problems solved by technology

The disadvantage of the background technology is that the X-prism is made of four right-angle prisms glued together, which requires high processing precision, complicated process, difficult coating design and coating process, and expensive production cost.
The X-prism color combiner is a fixed structure, which cannot be recombined and arranged. It can only combine three colors of light, and cannot be combined into a multi-color light color combiner of more than three colors.

Abstract

Belonging to photoelectric illumination and display technical field, the device for joining colors contains six optical modules. Being in range of visible light, centered waves of the six optical modules are from lambda 1 to lambda 6 in sequence from most to least. Optical module with centered wave being as lambda 1 is coupled to other two, three, four or five modules in the five optical modules to constitute device for joining three, four, five, and six colors light. Advantages are: easy of designing and preparing film series of spectrum film, flexible structure, capable of constituting device for joining multiple colors lights, high brightness and color saturation etc. The device is especially suitable as illuminated light sources utilized in LCD,DLP,LCOS etc display system.
