Ceramic LED street lamp light source

Abstract

The invention discloses a ceramic LED street lamp light source, which comprises a substrate, an LED chip packaged on the substrate, a light distribution part covering the LED chip and circuit wires connected with the chip, and is characterized in that: the substrate is a radiation ceramic substrate; and the LED chip is directly fixed on the ceramic substrate. The LED chip is packaged on the ceramic substrate directly, so the ultrahigh radiation performance of alumina / graphite ceramic material is utilized, complex structures such as heat sink and aluminum substrate are saved completely, the ceramic substrate is contacted with the outside directly, and the radiation effect is direct and quick. Thus, the structure of the light source is simplified greatly; the cost of the light source is low; and the material requirements and consumption of the light source are reduced. In addition, the independent parts of the LED light source are integrated into a modular structure integrating packaging, light distribution, radiation and circuit wires.

[0002] LED light sources are widely used in the field of lighting equipment. Because of their low cost, long life, and low power consumption, they have good development prospects and their application fields continue to expand. Generally, LED light sources are composed of LED chips, heat dissipation, and packaging. They are generally called The focus of improvement is nothing more than the two major parts of emission technology and packaging technology. Heat dissipation and packaging determine the service life and luminous effect of LED chips. At present, the structure of LED street lights on the market is basically composed of shells, metal radiators , aluminum substrate, LED lamp beads, LED lens, and switching power supply; each part is independent of each other, and must be processed and assembled to form a whole. The process is quite complicated, and there are many raw materials required. Large, heavy, surface-to-face and high cost; LED street light products themselves are environmentally friendly products that emphasize energy saving and emission reduction. If the product itself needs to consume a lot of raw materials, it is not a perfect low-consumption product, especially the heat dissipation of the LED street light source. The device part requires a lot of metal materials, and the extraction and processing of metal materials will cause great damage and impact on the earth's environment. The market promotion of LED street lamps has played a great hindering role
