Kang Rong Cup heat sink contest attracts attention
October 20, 2022
"High light efficiency, high cost performance" has always been the direction of the LED industry, and LED lighting products is a systematic product, and the smooth flow of "optical channels, electrical channels, hot channels" is a key factor.
In the work process of LED lights, less than 20%-30% are converted into light energy, and about 70%-80% of the energy is converted into heat energy. If this part of heat energy can not be dispersed in time, it will cause the light source to burn, but also cause the chip junction temperature to rise, the life expectancy decreases, the luminous flux drops. Therefore, when making LED lighting, it is very necessary to use a reasonable radiator.
Heat dissipation not only allows the light source to dissipate heat, but also allows the power supply to dissipate heat. Cai Ming, manager of Shifuduo Optoelectronics Product Management Department, stated that the selection of heatsinks by application vendors is a result of comprehensive consideration. “We have comprehensively evaluated various factors such as performance, price, transportation, and installation of heat-dissipating materials to select the most appropriate heat sink.”
At present, the main cooling materials on the market are aluminum, plastic-clad aluminum, plastic-clad ceramics, plastics and ceramics. For the choice of heat-dissipating materials, Cai Ming said that various materials have their own advantages and limitations, mainly according to the characteristics and requirements of the lamps. Select "If you use a non-isolated power supply, you must consider the safety problem, and choose to plastic aluminum; the heat sink must match the performance of the entire light fixture, can not let the heat become the short board of the light fixture."
Since the beginning of this year, the strong growth in the demand for LED lighting terminal market has also driven the rapid growth in the market demand for lighting cooling kits.
At present, there are no unified market access standards for all segments of the domestic LED lighting industry, and they are in a mixed state. The heat sink is even more so. Kang Rong, director of the Kang Rong Research Center, held the "2013 Kang Rong Cup National Radiator Design Competition on November 6th. "The launch ceremony said: "The purpose of hosting the heat sink design competition is to remind the LED lighting industry to pay attention to the safety of radiators and make substantial improvements in the performance of the radiators."
Senior Engineer CEO Zhang Xiaofei said that from the recent LED lighting market conducted by Gaogong LED, the results showed that the lamps with quality problems generally have poor heat dissipation. "To grasp the quality of LED radiators and improve the performance of LED lamps is an urgent task." Zhang Xiaofei pointed out that Gaogong LED's contract for the Kang Rong Cup national heat sink design competition is also a good example for the industry.
The 2013 “Kang Rong Cup National Heat Disigning Body Design Contest” was formally launched in November 2013 and ended in May 2014. It was divided into four stages. Since the start of the Contest, it has received strong support from the industry and has participated enthusiastically. In the hot registration stage.
