LED is a new solid-state light source, since its inception has been a great concern. Its luminescence mechanism is by the PN junction between the electrons in the energy band transitions of light energy. Under the effect of external electric field, the radiative recombination of electrons and holes occurs electroluminescence effect, part of the energy is converted to light, radiation recombination remaining lattice vibration energy into heat.

Currently LED luminous efficiency is only 20% to 30%, the rest are mostly converted into heat energy, a lot of heat to dissipate the need for timely, otherwise it will reduce the life of the LED, or even permanent failure. Therefore, the rapid development of the LED, and people are constantly engaged in research of new technology LED heat dissipation.

With aluminum metal density, high thermal conductivity, surface treatment technology is mature and the advantages of LED lighting has been dominated by the main material in the market. As people on the safety performance requirements increase, the conductivity of aluminum become a deadly scar, in order to improve the safe use of LED lighting, electrical insulating materials attracted people's attention.

Began to emerge of an electrically insulating material has a high thermal conductivity ceramic materials and plastics. Human use of ceramic materials has been for thousands of years, modern technology has produced ceramic insulation, high thermal conductivity, infrared radiation rate, low coefficient of expansion characteristics, can become the new material of LED lighting. At present, the ceramic material is mainly used for the LED package to the heat sink material chip, the circuit board material,ceramic lamp holder and a heat sink material lamps. By virtue of its high thermal conductivity of plastic excellent electrical insulating properties and low density value, high-profile heat sink material into the market, at this stage because the price is high, the application rate is not, and ceramic materials will have a very good advantage.
