Fraunhofer IIS develops integrated, low-cost color sensor for controlling LED lighting
Nürnberg, June 2, 2014: Researchers at the Fraunhofer Institute for Integrated Circuits IIS in Erlangen, Germany have developed a color sensor with an integrated on-chip filter for controlling color and brightness fluctuations that can occur with LEDs. Nanostructured metal layers for spectral filtering, combined with an underlying layer of photodiodes, can be utilized in a feedback loop to control colors, thus ena-bling defined color perception. The low-cost CMOS (complementary metal ox-ide semiconductor) process used to manufacture the color and multispectral sensors promises broad utility. Researchers will be presenting a prototype at the SENSOR + TEST trade fair in Nürnberg from June 3 to 5, 2014 (hall 12, exhib-it booth 12-537).
