Abstract

The invention relates to the technical field of light-emitting diode (LED) light sources, and discloses a multicolor adjustable LED structure which comprises a substrate. A light-emitting area is arranged on the substrate; a box dam divides the light-emitting area into a first light-emitting area and a second light-emitting area; the first light-emitting area is provided with a first LED chip forforming a white light and a second LED chip for forming a white light; the second light-emitting area is provided with at least three auxiliary LED chips for emitting different-colored lights; the first LED chip, the second LED chip and the auxiliary LED chips are electrically connected with an anode bonding pad; the first LED chip is electrically connected with a first white light bonding pad; the second LED chip is electrically connected with a second white light bonding pad; the auxiliary LED chips are electrically connected with an auxiliary chip bonding pad; through controlling the supplycurrent magnitudes of the first LED chip, the second LED chip and the auxiliary LED chips, the light-emitting brightness is adjusted, the color temperature of the emitted lights is further adjusted,the color temperature of the mixed light is freely adjusted within the range of 3000K to 7000K according to the actual demand, and RA is larger than 95, so that the product performance is improved, and the diverse needs of users are met.

Description

technical field [0001] The invention relates to the technical field of LED light sources, in particular to a multi-color adjustable LED structure. Background technique [0002] LED is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. [0003] LED has a series of incomparable advantages of traditional light sources such as energy saving, long life, no fear of vibration, green environmental protection, impact resistance, etc., so LED occupies a major share in the existing light source market, and various LED light source products are springing up. emerge like. [0004] Patent No. CN107202256A discloses at least two LED chips with different color temperatures or colors to mix light, but it is limited to filament LEDs, and cannot achieve dimming within any color temperature range from 3000K to 7000K and RA above 95; patent No. CN206271758U The patent discloses the RGBW bracket and its l...
