The chart shows the measuring white brightness circuit diagram composed of LX1970 visible light sensor. The visible light emitted by light source which is composed of UCC, white LED and current source and then visible light is received by the LX1970 and converted into current signal. In the SNK, SRC ends are connected with a microammeter in series, which are used to measure photocurrent ISNK, ISRC, microampere meter readings can reflect the level of brightness.
