In 2012, the LED industry was ups and downs: production disorder, overcapacity, quality chaos, bankruptcy, corporate price wars, consumer trust in LEDs decreased... In 2013, with the development and reform commission and other six ministries jointly released " Semiconductor Lighting Energy-Saving Industry Planning", a number of favorable industry development plans have been launched, LED industry has ushered in a good opportunity for development, industry changes, how to choose companies, in order to keep up with the development of the industry, occupy a strong position in the market? Hear Mr. Du Jianjun, Chairman of Shenzhen Overclocking Technology Co., Ltd. to talk about the development of the company.
I. Inheritance and breakthrough: Conquering the thermal fortress
According to the reporter, in 2010, with more than 180 self-developed patented technology of domestic famous brands electrical and mechanical cooling PCCooler Technology Co., Ltd. strong attack LED market, promote the new concept of LED heat sink. At present, the luminous efficiency of LEDs is still low, which causes the junction temperature to rise and the lifetime to decrease. In order to reduce the junction temperature to improve the life, the heat dissipation problem is extremely critical. The heat dissipation design of the LED must be from the beginning of the chip to the entire heat sink, and every link must be highly valued. Neglecting any part of the design will cause serious heat dissipation problems. In the past, LED street lamps suffered a large number of failures in long-term work, half of which was caused by lack of heat dissipation design, and the other half was caused by power failure. Therefore, the design of heat dissipation must be given full attention.
According to Du Jianjun, the product technology of Overclocking III is passed down from the traditional CPU cooling and improved. Overclocking three has reached the first place in the PC cooling market. The principle and foundation of LED cooling and CPU cooling are the same. It is necessary to solve the problem of deriving and dissipating the heat dissipated by the chip; all solving the heat dissipation problem with the chip as the heat source, so the overclocking three inherits the advantages of the PC heat dissipation technology , and invents a series of heat dissipation technologies such as heat pipe riveting to solve the problem of high-power LED heat dissipation. problem;
Du Jianjun said that with the inheritance of technology, the products cannot be separated from the vigorous investment in R&D and innovation. The focus of the overclocking three companies in 2011-2012 has been invested in product research and development. At the end of 2012, overclocking three industrial and mining lamp floodlights The single high-power LED radiator used in the Guangdong Province won the award for the product technology selection of the “Province Cup†in Guangdong Province. However, due to the fact that the company’s focus is not on marketing, the sales of the products for the whole year of 2012 are general. In 2013, overclocked three LED products were recognized by the industry. Du Jianjun said that in the first quarter of this year, overclocking three LED radiator products revenue reached tens of millions of yuan. The company is full of confidence in this year's situation. "The overall momentum this year is good. We strive to achieve a 5-8 times increase in the year-end results compared with the same period last year." Du Jianjun said with confidence.
1. Application of inventing heat pipe technology in heat dissipation of high power LED
Du Jianjun introduced the heat pipe technology in 1963, the Los Alamos National Laboratory invented the heat pipe, mainly used in aerospace, military. Using the principle of heat conduction, the closed casing is filled with a working medium and heat exchange is performed by utilizing the phase change endothermic and exothermic of the medium. Thermal conductivity exceeds any known metal. Overclocking three invented the heat pipe riveting fin technology, the heat pipe uses the vapor and liquid phases of the internal medium to change heat conduction, and the high-density heat flow is transmitted from the LED light source to the fin. Large-area fins dissipate heat, quickly reducing the temperature of the light source and extending the life of the light source.
