LED light source structure

Abstract

The invention discloses an LED light source structure. The LED light source structure comprises a substrate, LED chips and two output ends. The substrate is provided with a plurality of series connection sets composed of a plurality of the LED chips, and the multiple series connection sets are connected in parallel. One ends of the series connection sets are connected with a positive pole end, andthe other ends of the series connection sets are connected with a negative pole end; the two output ends include the first output end and the second output end. The LED light source structure is highin brightness, good in heat dissipation effect, large in light emitting angle and more concentrated in light emission; two-way output can be achieved, and two-way output can be controlled independently or simultaneously; the low series number is adopted so that traditional low voltage power drive on the market can be achieved; two-color-temperature output can be achieved.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to an LED light source structure. Background technique [0002] Compared with traditional LED point light sources, LED surface light source lighting products have obvious advantages, especially in terms of color rendering, heat dissipation, light decay, lifespan, lighting effect, failure rate and other aspects. The traditional LED light source belongs to laser products, so the light output effect is very dazzling, which cannot meet the occasions with high requirements on light efficiency, color rendering and other parameters. Some LED products can only play a lighting effect, but the LED surface light source is greatly improved. Solving this problem, the color rendering index has reached more than 85, which can replace traditional energy-saving lamps, halogen lamps, metal halide lamps and other places with high lighting requirements. The traditional LED high-power light sour...
