[High-tech LED reporter Zhu Chunwei] On November 26th, in the third session of the CTO conference held in conjunction with the 2013 Gaogong LED Lighting Exhibition, the title of the photovoltaics was held: the packaged devices, equipment and materials II were held in Hall 5, Guangzhou Poly World Trade Center. The meeting was hosted by Dr. Jin Peng, a professor at Peking University Shenzhen Graduate School.
Since the beginning of this year, the LED commercial lighting and engineering lighting markets are rapidly picking up. In the increasingly fierce market competition, the comprehensive performance competition of various LED lighting companies has become one of the key factors to win the market. Among them, the problem of heat dissipation of lamps has always been one of the bottlenecks to be solved.
Han Junzhong, the marketing director of Radsang Energy Technology, gave a speech on “How to choose a good LED radiatorâ€. It is well known that during the operation of LED lamps, less than 20%-30% is converted into light energy, and about 70%-80% of energy is converted into heat energy. If this part of the heat energy can not be dissipated in time, the heavy light will cause the light source to burn out, and the light will also cause the junction temperature of the chip to rise, the lifespan to decrease, and the luminous flux to decrease. Therefore, when doing LED lighting, it is necessary to use a heat sink. However, how to choose a good radiator? We should mainly consider the following aspects: the material of the radiator, the structure of the radiator, and the core technology of the radiator.
“For example, in some short-term special high-temperature conditions, in order to protect the light source from irreversible damage, can it be adjusted by means of power supply; the thermal conductivity of the heat-conducting medium between the light source and the heat sink is not high or the life cannot meet the requirements. Replace with other media, etc." Han Junzhong said that LED products are important, but the overall service level is more important, because the end customer needs a perfect, reliable product.
