Outdoor ceramic high-power LED (light-emitting diode) light source

Abstract

The invention relates to an outdoor ceramic high-power LED (light-emitting diode) light source, which is used for solving the technical problems that a traditional high-power LED can absorb water and moisture easily, has the bad cohesiveness with a potting adhesive and is weak in air tightness. The LED light source comprises a substrate and a light-emitting chip which is arranged on the right side of the substrate, wherein the substrate is made of DPC (diphenyl carbonate) ceramic plates; and a nonopaque body is formed in the middle of the right side of the substrate by injection molding and covered on the light-emitting chip as well as connected with the light-emitting chip and the surface of the substrate in a sealed mode. The outdoor ceramic high-power LED light source has the advantages that the substrate which is made of the DPC ceramic plates does not absorb the water and moisture, thus ensuring the service life of the LED light source; the nonopaque body is formed by the injection molding, thus ensuring the air tightness of the high-power LED light source; and reflow soldering can be carried out on the ceramic high-power LED light source so as to improve the production efficiency.

Description

technical field [0001] The invention relates to an LED light source, in particular to an outdoor ceramic high-power LED light source with moisture resistance, good air tightness and high production efficiency. Background technique [0002] Traditional high-power LEDs are based on high-temperature PPA materials. The material is easy to absorb moisture and water, and has poor adhesion to potting adhesives. It is easy to cause high-power LEDs to fail due to moisture. Power LED dead lights, most of the high-power LED dead lights on the market are damp due to poor air tightness of the LEDs, which makes high-power LEDs unable to be widely used outdoors. At the same time, most traditional high-power LEDs cannot be reflowed. It can be welded by hand, so the production efficiency is low during application. For example, the authorized announcement number is CN201562691U, and the name is a Chinese utility model patent for a full-color SMD LED, which includes a bracket, a chip, and a g...

AI Technical Summary

Problems solved by technology

[0003] The invention mainly solves the technical problems that traditional high-power LEDs are easy to absorb water and moisture, has poor adhesion to potting adhesives, and poor air tightness, and provides an outdoor ceramic with moisture resistance, good air tightness, and high production efficiency. High power LED light source

In the present invention, the DPC ceramic plate is used as the substrate, which solves the problems that the traditional LED uses high-temperature PPA material as the base, which is easy to absorb moisture and water, has poor adhesion with potting glue, and cannot pass reflow soldering and has low production efficiency.
