[Text|High-tech LED reporter Gan Qin] 2014 High-tech LED annual meeting was held in Dongguan Guanlan Lake Dongguan Club on December 12-13. On the morning of the 13th, the theme conference of Zhongheng Paiwei was named, Moso Power Liu Yaoping, vice president, gave a keynote report titled "Research and Prospects of LED Driver Power Technology".
Under the dual pressure of cost and quality, a new driving method - "de-energizing" technology came into being. At present, the design ideas for de-energizing mainly include AC-LED and HV-LED.
Liu Yaoping said that the power supply to the power supply is a new technical direction, with obvious advantages such as low cost, small size, easy automatic biochemical production, longevity and reliability improvement. However, the technology is still not mature yet, and will it become a trend. Need to go through technical and market testing.
Liu Yaoping said that the current power-off technology is mainly limited to small power supplies, mainly used for indoor LED power supply within 60W, including indoor and commercial lighting and home lighting. In the high-power outdoor road lighting power supply, There is basically no impact. The traditional drive power source occupies a commanding height in the middle and high-end market due to its good voltage adaptability, lightning resistance, withstand voltage, no stroboscopic, and intelligent control characteristics, especially in the field of outdoor road lighting.
Based on this, Liu Yaoping believes that the future drive power technology will form a situation where the de-energized drive and the traditional drive coexist, which is determined by the technology and market positioning.
In addition, in the LED drive power market, there are also a series of problems such as “how to improve cost performanceâ€, “how to improve efficiencyâ€, and “how to improve life, reliability, and realization of intelligenceâ€.
Liu Yaoping concluded that to solve the above problems, LED drive power companies must develop in the direction of “standardizationâ€, “modularization†and “intelligence†in the future.

The first is stroboscopic, which is caused by the characteristics of the alternating current, and its brightness will change with the periodic change of the commercial power to form the stroboscopic light of the LED light source. Secondly, due to the lack of electrolytic storage capacitor, the drive cannot function. Very good function of stabilizing voltage; de-energization also has problems such as resistance to grid fluctuations, resistance to voltage, and lightning (shock); in addition, power supply is not suitable for intelligent control; There is no corresponding safety regulation for the light source, and it is difficult for the product to obtain a market permit.Liu Yaoping said that the current power-off technology is mainly limited to small power supplies, mainly used for indoor LED power supply within 60W, including indoor and commercial lighting and home lighting.
