Abstract

The concept of a high-luminance light source based on luminescent conversion of LED light and optical concentration in a transparent phosphor is explained. Experiments on a realized light source show that a luminous flux of 8500 lm and a luminance of 500 cd/mm2 can be attained using 56 pump LEDs at 330 W electrical input power. The measurement results are compared to optical simulations, showing that the experimental optical efficiency is slightly lower than expected. The present status enables applications like mid-segment digital projection using LED technology, whereas the concept is scalable to higher fluxes.

Fig. 1 (a) Schematics of luminescent light source: light emitted from blue LEDs is absorbed in a luminescent rod. Most of the emitted light is guided by total internal reflection to an edge of the rod, where it is extracted, e.g. using a CPC. At the other edge, a mirror is placed. (b) Mechanical drawing of the module. Through the rectangular aperture at the front, the exit window of the CPC is visible, which is mounted on the luminescent rod.
