[Text|High-tech LED reporter Luo Shenghua] LED driver power supply is an indispensable part of LED lighting products. It brings a lot of cost pressure to lighting companies, and it is also one of the main factors affecting the stability of LED lighting products.
"Power is the 'heart' of outdoor lighting." Ye Jianbo, general manager of Hangzhou Zhongheng Paiwei Power Co., Ltd. stressed that in the cause of outdoor lighting failure, heat dissipation accounted for 31%, LED components accounted for about 10%, and power and control The failure of the drive module accounts for 59%, and the quality of the drive power directly affects the life of the lamp.
The power supply is a product that handles voltage and current conversion, and controls dangerous voltages with small signals. Generally, it includes active components, passive components, and mechanical components. The number of components in high-power power products is generally several hundred to thousands. The failure of one component may cause the entire power supply to work abnormally. Mismatch between components may also cause abnormalities in the product.
The high-power device is in the "switch" working state, which is the source of electromagnetic interference, which not only interferes with the outside world, but also interferes with internal small signals. In particular, the outdoor power supply has a complicated working environment, in addition to various factors such as high cold, high temperature, high humidity, lightning strike, corrosion, and grid voltage fluctuations.
The relatively high threshold of outdoor power supply, although to some extent avoids the fierce competition similar to the medium and low power supply, but at the same time puts higher requirements on the technology of the enterprise.
"LED driver power technology is difficult and difficult to develop. The product needs long-term experience to accumulate the results of life test. In the manufacturing process, it is necessary to ensure dustproof, anti-static, poor solder joints, poor incoming materials, quality inspection, etc. The link checks." Ye Jianbo believes that the outdoor application scene is complex, and the drive power market has a large capacity. It is difficult to recall when there is a problem, so the quality requirements of the drive power supply are more demanding.
As the industry's highest specification and largest industry event in the LED industry, it is also the best platform for the annual LED industry's year-end review, analysis and outlook. So far, the high-tech LED conference has been successfully held for four sessions. The 5th High-tech LED Conference will also be held at the Guanlan Lake Dongguan Club in Shenzhen on December 12-13, 2014.
Ye Jianbo, general manager of Zhongheng Paiwei, will deliver a keynote speech on “Quality is the lifeline of outdoor lighting power supply†at the sub-forum “Looking forward to the new chapter of LED for the next three years†on the afternoon of December 13th of the 2014 High-tech LED Annual Conference. Discuss with the participants on related topics, so stay tuned!
