[Text / high-tech LED reporter Zhu Chunwei] "COB has the advantages of low thermal resistance, solder-free, good light quality, low cost, etc., will become the mainstream of future packaging applications. At present COB has been successfully applied to many types of lamps, large The popularity of scale is also just around the corner,” said Xia Xuesong, general manager of Guangzhou Silicon Energy Lighting Co., Ltd.
“Seeing no light, everything is luminaire.” This is the foresight of silicon lighting based on the development trend of LEDs and the future light environment proposed by the continuous research and development of COB packaging.
As one of the largest COB device manufacturers in mainland China, Silicon Energy has achieved breakthroughs in wire bond strength, color difference control, luminous efficacy, lumens and other performances, and continuously improved the performance of COB light sources. The main members of the technical team are from the Semiconductor Lighting System Research Center of Sun Yat-Sen University.
Silicon energy lighting COB covers the specifications of various lamps to meet the overall needs of indoor general lighting. Five standard COB series are available for different applications: high light type, high voltage type (including AC and DC), high power type, mixed light type and F-type.
For example, the circular 5W COB in the above figure, 5 strings of LED chips, the highest luminous efficiency can reach 110lm / W, the index is 70, the current is 300mA, can be widely used in home and commercial lighting bulbs, MR16 small Spotlights and other aspects.
“With our excellent technology, we have successfully entered the first camp of mainland COB manufacturers. The ultra-high-cost packaging products have won the trust of many customers.” But in Xia Xuesong’s view, COB is still a relatively new package. Form, there are not many people accepted. To make everyone aware of the need to promote the promotion of enterprises and third-party institutions.
The 2013 High-tech LED Lighting Exhibition, which will be held at the Guangzhou Poly Exhibition Hall on November 25th, is seen by Xia Xuesong as the best choice for Silicon Lighting to continue to expand the company's COB device market. “High-tech LED lighting exhibition is a very large LED lighting supply chain communication platform with large scale, professionalism and authority.”
