Abstract: A driving circuit for a solid state lighting apparatus includes a full wave rectifier configured to rectify an alternating current (AC) input voltage signal to generate a rectified input signal, a boost conversion circuit configured to receive the rectified input signal and responsively generate a direct current (DC) output voltage signal and to supply the output voltage signal to a solid state light source, and a boost control circuit coupled to the boost conversion circuit and configured to cause the boost conversion circuit to operate in a constant power mode.
Abstract translation: 固体照明装置的驱动电路包括全波整流器，被配置为整流交流（AC）输入电压信号以产生整流输入信号;升压转换电路，被配置为接收经整流的输入信号并且响应地产生直流 （DC）输出电压信号，并将输出电压信号提供给固态光源，以及升压控制电路，其耦合到升压转换电路并且被配置为使升压转换电路以恒定功率模式工作。
