Application of phonon heat dissipation material in LED products
Yan Xuehua, General Manager of Ningbo Global Optoelectronics Co., Ltd., gave a report titled "Application of Phonon Heat Dissipation Materials in LED Products" at the "Municipal Lighting Energy Saving Products and Technology Exchange Conference".
The report pointed out that in order to enter the field of lighting, LED must use the system method to study the LED heat distribution model, and use new materials and new structures to solve the problem of LED heat transfer and heat dissipation.
For lighting to be LEDized, the key is to improve luminous efficiency and luminous flux - high power LED devices. Power LEDs have the biggest obstacle to high luminous flux: low light extraction efficiency, in addition to chip technology, thermal management, optical design must be optimized design and research.
In the report, General Manager Yan Xuehua listed the quantum theory of high-frequency phonon heat dissipation aluminum thermal motion: classical heat capacity theory, Einstein quantum heat capacity theory, and Debye quantum heat capacity theory. It is pointed out that we discuss the solid heat capacity is still to reveal the characteristics of atomic thermal motion, and the complete introduction of heat capacity statistics theory should be the content of statistical physics. There should be a correct view of the theory.
When referring to the phonon heat-dissipating aluminum, General Manager Yan Xuehua believes that with the thermal imager, the temperature measurement is not accurate and must be measured using the far-infrared tester.
The report also introduces the use of LED functional lighting technology such as 1LED package quantum cut light-emitting chip technology, LED package solid crystal glue technology, LED thermal conductive rubber material technology, LED quantum modulation phonon heat dissipation aluminum technology, LED electroless power supply technology.
