Abstract

The invention discloses a full color COB light source which comprises an LED substrate, a positive electrode bonding pad, a negative electrode bonding pad, an IC integrated circuit chip, a chipset assembly, a box dam and a diffusion layer, wherein the positive electrode and negative electrode bonding pads are arranged on the LED substrate; the IC integrated circuit chip is connected with the positive electrode bonding pad; the chipset assembly is connected with the negative electrode bonding pad and the IC integrated circuit chip, and surrounded by the box dam; the diffusion layer covers the chipset; the chipset assembly comprises a red light chipset, a green light chipset and a blue light chipset which are connected with the IC integrated circuit chip through a red light chip output circuit, a green light chip output circuit and a blue light chip output circuit respectively. The full color COB light source has the advantages that red light chips, green light chips and blue light chips of an LED are combined together, and the constant current supplied to each LED chip can be controlled through the IC integrated circuit chip to ensure that the LED chips can generate light of three primary colors, including red, green and blue. Therefore, the color temperature of white light also changes, and full color visible light is formed through mixing.

Description

technical field [0001] The present invention relates to a full-color COB light source, in particular to a full-color COB light source that controls the operating currents of three chips through an IC integrated circuit chip to make them emit three primary colors of red, green, and blue light to realize mixing into full-color visible light. . Background technique [0002] The mixing of full-color COB into white light is also a kind of white light LED. Usually, the chips of the LED are combined, and the current is used to make them emit various primary color lights, and then mixed into full-color visible light. However, the existing full-color COB light source does not design a constant current control to supply the current of each chip of the LED, and it is easy to cause the main wavelength shift caused by the change of the LED operating current to change color, and the effect is not good and the service life is short. Contents of the invention [0003] The purpose of the ...
