Structure of LED light color mixing circuit

Abstract

The present invention provides a structure of color mixing circuit of LED light. The LED light includes two input terminals and two output terminals. The two input terminals are respectively an input terminal of reverse parallel connection of any two light-emitting chips of three primary-color light-emitting chips of R, G, B and an anode input terminal of the remaining light-emitting chip and the two output terminals are respectively an output terminal of reverse parallel connection of any two light-emitting chips of the three primary-color light-emitting chips of R, G, B and a cathode output terminal of the remaining light-emitting chip. The structure is simple and the purposes of reducing the number of IC control chips and synchronous color change of light-emitting chips are achieved with modification only made on electrical connection among the three primary-color light-emitting chips in realizing operation of a group of LED lights connected in series.
