TWO-COLOR COB LIGHT SOURCE

The present invention relates to the technical field of intelligent lighting. Particularly disclosed is a two-color COB light source, comprising a substrate, on which a power supply positive bonding pad, several sequentially connected warm light chipsets, several sequentially connected cold light chipsets and several negative bonding pads are provided, wherein the warm light chipsets and the cold light chipsets are respectively electrically connected to the power supply positive bonding pad and the negative bonding pads; and the power supply positive bonding pad and the negative bonding pads are arranged in sequence around the warm light chipsets and the cold light chipsets. In the present invention, by means of a unique circuit layout, a flip-chip circuit is applied to wire bonding, and a wire-bonding effect is achieved, so that a wire-bonded substrate has both a flip-chip circuit design and the light emitting efficiency characteristic of wire bonding; and a two-color light emitting effect can be achieved.
