20130294103 | COLOR TEMPERATURE TUNABLE LED-BASED LAMP MODULE - A light mixing and folding lamp includes an LED assembly with two or more LED chips that direct light into the ingress end of a light mixing rod. The light mixing rod is positioned to pass through an aperture in a concave second reflecting element, and mixed light emerges from the egress end of the light mixing rod, where it is directed toward a first reflecting element positioned near a focal point of the second reflecting element. The first reflecting element reflects mixed light emerging from the egress end of the light mixing rod, folding the mixed light back toward a concave reflecting surface of the second reflecting element. The second reflecting element reflects light from the first reflecting element forward, where the light emerges from the lamp directed toward a subject to be illuminated. | 11-07-2013 |

20140218935 | Illumination Unit with Optical System - Various embodiments of the illumination unit include a surface light source, a primary optical element, a first reflector and a second reflector. The primary optical element is arranged at the surface light source in such a way that light emitted by the surface light source is imaged onto the first reflector by the primary optical element. The beam cross section of the light is reduced by the primary optical element at the same time. In this case, the first reflector images the light beam that has been reduced by means of the primary optical element onto the second reflector in order to emit the light from the second reflector from the illumination unit. | 08-07-2014 |
