LED-Illumination Systems

#

In order to make use of the benefits of modern LED technology in general lighting, including high electro-optical conversion efficiency, controllable color and long useful life, precise free-form optics are required. These optics transform the radiation patterns of the LEDs used into, for example, the far-field distribution required for street lighting, optionally homogenize with facetted reflector surfaces or transmissive honeycomb condenser optics and enable the partitioning of LED radiation in spot arrays.
