description The utility model provides a LED (light emitting diode) drive circuit, including power switching circuit for be the direct current with the ac inversion of input, load circuit, load circuit with power switching circuit is connected, load circuit includes two at least LED branch road circuit that connect in parallel each other, every LED branch road circuit include emitting diode and with the positive temperature coefficient inductance that emitting diode establishes ties. This LED (light emitting diode) drive circuit, series connection positive temperature coefficient inductance on emitting diode, when the electric current that passes through when LED branch road circuit changed, the temperature on the inductance also changed thereupon, and then results in the change of inductance value to the electric current size that realizes adjusting this LED branch road circuit is with the purpose that reaches the current -limiting and flow equalize. 本实用新型提供了种发光二极管驱动电路，包括电源转换电路，用于将输入的交流电转换为直流电；负载电路，所述负载电路与所述电源转换电路相连接，所述
