22 September 2011 Optical system design for a reflector-based LED food lighting module
Author Affiliations +
We report on the development and experimental analysis of an LED lighting module for use in a high-end food lighting environment which puts high demands on color homogeneity and color rendering. The system is built from highly reflecting and partly scattering PVD coated metal reflector sheet that has limited deformability and uses RGBW LEDs. We develop an optical design that is adapted to allow for color mixing and to take into account manufacturing constraints and include this into a prototypical module. Results of measurements and field tests are in good agreement with simulations.
