Rare earth become LED green lighting new hope in China

LED green lighting industry at home and abroad, is a "hot" industry. Says it is "hot", on the one hand, the LED green lighting the future in terms of energy conservation and emissions reduction and low carbon economy investment in environment protection value and market value on the "hot" in the industry. And, on the other hand, because objectively LED itself has a feature which is both light and heat, many LED products at present unable to solve the problem of heat dissipation and cause products "hot".

In the industry, rare earth metal is known as the "industrial monosodium glutamate", by adding rare earth elements can miraculously improves the performance of the material, now, rare earth materials have been widely applied in many industries. In high power LED lighting products, rare earth phosphors is not as raw material, and in the light distribution, tables, coated and thermal aspects began to play a new role.

Suzhou in jersey, said photoelectric technology co., LTD., head of heat dissipation is the key factors influencing the high power LED practicability, by using the coefficient of thermal conductivity is as high as 100 w/(m · ℃) of rare earths liquid metal at room temperature to replace the traditional solid crystal silver glue and thermal conductive paste binder and filler, can reduce the thermal resistance, broke the heat dissipation of high-power LED the bottleneck. In addition, the use of rare earth alloy materials, radiator can increase the heat transfer, effectively promote the heat dissipation. After many years of concentrated study of rare earth materials, applied to the encapsulation of the LED lamps and lanterns, thermal conductivity, thermal, optical lens and lamp shell structure design, and other key link, to realize the combination of new materials and innovative technology, solved the high power LED lighting lamps and lanterns of heat and light distribution is international problems.

In addition, in order to further improve the reliability of the LED, the same excellent thermal conductivity of the rare earth ceramic packaging substrate instead of the traditional metal substrates, can effectively avoid the chip and the substrate. In the glass lens doped with rare earth elements, can reduce the coefficient of light absorption and dispersion of lens, increase the rate of pervious to light. Visible, rare earth materials in the high power LED lighting lamps and lanterns has played an important role, solve the heat dissipation of the LED lamps and lanterns, light distribution, packaging, and the key technical problem is helpful.

Abundant rare earth resources in our country, is expected to go a long way on the LED green lighting products, let us see the China LED green lighting new hope!
