The output colour distributions from red, green and blue (RGB) LEDs mixed with cross linked PMMA micro particle doped PMMA mixing rods is compared to output from a plain PMMA mixing rod. Distinctive patterns with clear ...

Transparent Refractive Index Matched Micro-particles (TRIMM) in polymer rods are highly efficient light mixers. This paper addresses the problem of estimating the optimum length for the mixing rods, for a given TRIMM-to-matrix ...
