[Source: Gaogong LED's "LED Good Products" December issue (total 60th issue) Wen | Gan Qin] The so-called de-powered, does not mean that no power is needed, but through other special techniques to improve. For example, removing some components such as electrolytic capacitors and transformers, the circuit design and the device are simplified to achieve the purpose of reducing the volume, reducing the cost, improving the reliability, and prolonging the life. However, this technical route has been the focus of debate in the industry since its appearance.
It is understood that the current industry from the technical level to achieve power, there are two main forms of expression: one is AC-LED (AC LEDs), and the second is HV-LEDs (high-voltage LEDs).
Chen Heng, general manager of 晟Distribution, said, “The reason for the poor performance of LED luminaires, 70% of the reasons can be traced back to electrolytic capacitors. The traditional switching power supply AC/DC drive has electrolytic capacitors that are easy to break, many components, poor performance, etc. Disadvantages, the future will gradually lose its competitive advantage.
"Our AC-LED driver IC's opto-engine architecture not only surpasses the AC/DC solution in terms of performance, but also has an absolute advantage in terms of cost." Chen Hengyu said that taking the lamp as an example, using AC-LED The solution can reduce the cost of the whole lamp by about 30%.
With the advantages of low cost and simple circuit, “de-energization†was once considered by the industry to be the future development trend of LED driver power.
Zhao Chunbo, deputy manager of Mingwei Electronics Marketing Department, said, "The trend of LED driver power supply is toward simplification. The power supply is simple and easy to produce, and the integration is high. The direction is right."
However, at present, there are still many technical obstacles to de-energization. There is still a lot of work to be done in the process of popularization, and stable voltage is one of them.
Wu Jianwei, chairman of Rungelai Electronics, said, “In the field of outdoor lighting, there is a big limitation in de-energizing because it cannot achieve high voltage and high current, or low voltage and high current.†In addition, de-energization can only be stable in the power grid. The use of the situation, and some unstable grids such as backward countries or regions are simply impossible to use.
Yin Baohua, executive vice president of Aihua Group, concluded that “the de-energization solution can solve the life problem of LED lighting fixtures, but because of the lack of capacitors, this energy storage component can not play a very stable voltage roleâ€.
