UCC, current source and white-light LED form thelight sources which can emit visible light, and thevisible light isreceivedand transformed into a current signal by the LX1970. The SNK port, SRC port arerespectively connected with a micro-table in series to measure optical flowing ISNK, ISRC, and micro-table reading value reflects the level of brightness.
