As LEDs continue to evolve, their utility or ability to produce light output from power supplies will only continue to increase. Secondly, LED lighting is environmentally friendly and does not require handling, exposure and disposal of toxic mercury vapors commonly found in cold cathode fluorescent lamps. Finally, incandescent bulbs often need to be replaced after about 1000 hours of use, while fluorescent lamps can last up to 10,000 hours. However, these figures are dwarfed by the fact that LED lighting can provide more than 100,000 hours of life. Heat dissipation, reliability and safety requirements need to be considered As is known to all, the operating temperature of the LED driver module is high, and the module has poor heat dissipation conditions, resulting in the LED driver circuit always operating at a higher temperature, which leads to a series of problems such as reduced reliability of the LED application and shortened service life. Have to focus on; reliability and safety are easily overlooked, especially before the implementation of the relevant regulations, in order to reduce costs, some LED lighting manufacturers will omit reliability and safety aspects of the circuit; but this is precisely The fundamental development of the LED lighting industry is also the embodiment of the LED driver chip manufacturers' design capabilities. The solutions provided by different chip manufacturers have greatly increased the cost of adding these circuits. Yu Zhongwei, product director of Taiwan's Accumulation Technology Co., Ltd., believes that the trend of standardization should be noted, such as the US Energy Star and Japan PSE specifications. In addition, dimming capabilities are gaining more and more attention, such as traditional thyristor dimming, 1~10V dimming, and DALI dimming. Finally, the requirements for the drive solution derived from solving the heat dissipation problem are not only cost considerations, but also lighter weight requirements, and must also take into account better electrical characteristics. LEDs require a rich power conversion and drive solution Lin Zhiyan, technical marketing manager of ON Semiconductor's lighting market, said that LED is essentially a low-voltage device. The forward voltage drop may vary between 2 and 4.5V depending on the color and current, and the LED needs to be driven by a constant current. Make sure to provide the required luminous intensity and color. At the same time, LED applications are diverse and require different power supplies, such as high-voltage AC-DC, medium-voltage DC-DC, and low-voltage DC-DC. This requires the use of suitable power conversion and LED drive schemes to drive LEDs, such as switch drivers, linear drivers, linear constant current regulators, and high voltage switching power supply solutions, power factor correction controllers, and even The novel lighting management ICs provide high energy efficiency and high reliability to meet the specific application needs, helping to take advantage of the long life of LEDs. Accumulation Technology also believes that the market has not blindly pursued the "one-time satisfaction" scheme, but has learned that there are conflicts between various characteristics. For example, under the traditional single-stage output architecture, power factor and output ripple cannot be optimized at the same time. compromise. Therefore, Accumulation Technology's strategy is to propose different solutions to different needs of customers. In terms of architecture, when the market has been unilaterally inclined to isolate solutions in recent years, accumulation believes that the non-isolated architecture can not ignore the irreplaceable advantages of specific applications, so it continues to develop diverse products. In addition to active power factor correction products, thyristor dimming and four-stage dimming products, the accumulation has been actively pursued towards a more cost-effective solution.
