    • The present invention relates to a hybrid constant current LED lamp. The LED lamp includes a rectifier unit, a filter circuit, a switching mode power supply, at least one main LED and a subsidiary LED. The main LED is electrically connected in series to the output terminal of the rectifier unit and the input port of the primary-side circuit of the switching mode power supply. The subsidiary LED is connected to the secondary-side circuit. The invention not only provides circuit architecture capable of providing a constant current, but also improves the power efficiency of the lamp.
    • 本发明涉及混合型恒流LED灯。 LED灯包括整流器单元,滤波器电路,开关模式电源,至少一个主LED和辅助LED。 主LED与整流器单元的输出端子和开关模式电源的初级侧电路的输入端口串联电连接。 辅助LED连接到次级侧电路。 本发明不仅提供能够提供恒定电流的电路架构,而且还提高了灯的功率效率。
