Application of phonon heat sink materials in LED products

Mao Xuehua, general manager of Ningbo global optoelectronics Co., Ltd., in the "municipal lighting energy saving products and technology exchange," on the issue of "phonon heat dissipation materials in the application of LED products," the report.

The report pointed out that if you want to enter the field of lighting, you must use a systematic approach to study the LED heat distribution mode, the full use of new materials, new structure to solve the problem of LED heat transfer, heat dissipation LED.

Lighting to LED, the key is to improve the luminous efficiency and luminous flux - high power LED devices. Power type LED to obtain high luminous flux of the biggest obstacle: low light efficiency, in addition to chip technology, thermal management, optical design must be optimized design and research.

In the report, general manager Mao Xuehua cited the quantum theory of the thermal motion of high frequency phonon heat dissipation: classical heat capacity theory, Einstein quantum heat capacity theory, Debye quantum capacity theory. It is pointed out that the purpose of this paper is to discuss the characteristics of the thermal motion of atoms, and the introduction of the theory of heat capacity statistics should be the content of statistical physics. Should have a correct view of the theory.

When referring to the phonon heat dissipation aluminum, general manager of China believes that the use of thermal imaging instrument, temperature measurement is not accurate, we must use a far infrared tester before the test.

The report also describes the 1LED packaging technology, LED light-emitting quantum cutting chip package solid crystal glue technology, LED thermal plastic material technology, LED modulation technology, quantum phonon heat radiating aluminum electrolysis power LED technology LED functional lighting application of new technology.
