The cooling performance of lamps and lanterns parade Kang Rong cup cooling design competition gradually into the climax

As can be seen from the LED light failure in the graph, the LED light failure related to its junction temperature. Junction temperature is higher, the earlier a droop, life will be shorter. Therefore, the key to extend the service life of the LED, is to reduce the junction temperature. And the key to reduce the junction temperature, is to have good radiator heat produced the LED out timely. As the key components of the supply chain, LED lighting industry radiator material improvement, the improvement of the design innovation and technology, plays an important role on the development of industry. Because of the LED light source, Lamp bead) And the power industry has gradually mature, in 2014, the LED lighting manufacturers will research and development center of gravity shifted to the radiator. A good radiator, not only should have good pass, heat dissipation function, also need to have good molding process. At the same time, under the circumstances of the radiator prices generally, in addition to the above performance, still need to have the advantage of price. Heat dissipation design boutique, therefore, to find the LED industry design talents with innovative spirit, promote the healthy development of the LED heat dissipation material industry 'Kang Rong cup national LED heat dissipation body design competition', and has entered the stage of sample lamp production and heat dissipation effect test. According to the organizing committee revealed that lasted more than five months 'Kang Rong cup' contest registration attracted a total of dozens of heat dissipation material enterprises to participate in the application, after the organizing committee of the early screening, from sun lighting, photoelectric, a photoelectric, blue and metal products, Kang Rong fine ceramics, yao lighting lighting, jiamei era, macro fai, fly Thai science and technology, intelligence letter illumination and so on dozens of excellent enterprise shortlisted to participate in the finished product lists the cooling performance of lamps and lanterns. The competition entries for 9 wled ball steep light heat dissipation suite. Participating enterprises will be unified use provided by the organizing committee of the lamp bead and power supply, made into 9 samples of wled ball steep light. The reporter understands from the organizing committee, this series use LED lamp bead and power supply, respectively is sponsored by si have photoelectric and dry star microelectronics. At the same time, competition designated third party inspection agencies for excitation test detection ( LTL) , specify the testing equipment for FLUKE FLUKE ( The infrared thermal imager Ti400) 。 Contest and invited mitsuo aurora, wood Tomlinson lighting, huayi lighting, byd lighting, lighting, wide bright starlight electric source, tongfang lighting, countries such as the industry well-known LED lighting enterprise CTO as judges. By then, the judges will according to the sample lamp working condition of the LED lamp bead temperature, cooling, cooling the weight, heat dissipation body size, shape, texture, appearance and heat dissipation ratio of each respect such as index, the entries for comparison. The competition big bonus, total nearly 80000 yuan, the award first prize a ( RMB 30000) Two, the second prize ( RMB 10000) Three, the third prize, RMB 5000) , honorable mention four ( RMB 2000) 。 Contest, the judges and awards ceremony on May 16, 2014 was held in the crowne plaza foshan. 2014 will be held in China LED lighting good product supply chain circuit foshan standing conference.
