摘要
LED作为第四代照明光源,具有节能、环保、体积小、长寿命等诸多优点。随着LED技术的日益发展成熟,它的应用越来越普及,特别是在大功率照明领域。因此LED的驱动电路的性能指标变得十分重要。本文简单介绍了LED驱动电路中的隔离型、非隔离型、LLC谐振型、无电解电容的LED驱动电路,并对它的发展现状和未来发展的趋势做了一定的分析。
As the forth lighting force, LED has many advantages such as energy saving, environmental protection, small volume, long life and so on. Its application becomes more and more popular. Thus the performance index of LED drive circuit is very important. This paper introduces the power factor correction and isolated, non-isolated, LLC resonant, no electrolytic capacitors LED drive circuit. And then it analyzes its development status and future trends.
