Abstract

The invention discloses a ceramic material radiator. The radiator is prepared by grinding and injection molding of the following raw materials in parts by weight: 96-116 parts of aluminum nitride, 1.5-3.5 parts of magnesium oxide, 10-20 parts of silicon micro powder, 8-12 parts of kaolin, 8-12 parts of zincite powder, 5-7 parts of titanium dioxide, and 8-12 parts of an injection molding substance.The ceramic material radiator provided by the invention not only has an environmental heat conduction function of a metal material, but also has a radiant heat conduction function, so that the radiator has more excellent heat conduction performance and insulating performance, and makes bulbs safer.

Description

technical field [0001] The invention relates to ceramic materials, in particular to a radiator made of ceramic materials. Background technique [0002] LED, also known as light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a bracket, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is encapsulated by epoxy resin. [0003] The country pays more and more attention to lighting energy saving and environmental protection issues, and has been vigorously promoting the use of LED lamps. However, the problem of heat dissipation has always been the key to the life of LED lights. Poor heat dissipation will greatly shorten the life of LED lights. The heat sink of the LED lamp in the prior art is mainly made of metal materials, but it...
