COMPACT LIGHT HOMOGENIZER |
摘要 |
<p>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.</p> |
