Abstract
Since several years light emitting diodes are in use to generate white light. Pixels with green, red and blue LED's are arranged to get any coordinate in the CIE--diagram with matched current for each diode. For instance Siemens Opto Semiconductor now OSRAM Opto Semiconductor offers multi chip LED's (LHGB T676) especially for the application above. A far better solution for producing white light represents luminescence conversion. The emitted light of blue diodes is used as a primary source for exciting organic or inorganic fluorescent. By conversion, `Stokes Shift', red, green, yellow and mixed colored light can be generated.Keywords
