Abstract

See full text

Provided are assemblies and processes for achieving desirable homogenization and mixing of one or more light sources. The assemblies include the use of diffusers and light pipes in a particular configuration that allows very good homogenization performance while reducing the requisite length of light pipe. In particular, a length of a light-pipe homogenizer can be substantially reduced by diffusing the light after it has been partially pre-mixed by a light pipe. Additional mixing can take place after diffusion. For example, a diffuser can be positioned within a light pipe or sandwiched between two light pipes. In some embodiments, the diffuser is placed at a point along a light pipe where the light from each source or each portion of a single source substantially covers the diffuser approximately equally. Consequently, a rate of homogenization can be increased, thereby reducing the required length of the complete homogenization system.
