    • An LED lamp unit (100) comprises: a unit input (101, 102) capable of receiving dimmed mains voltage (PCACV) from a supplying mains dimmer (1); a lamp driver (32) having input terminals (33, 34) coupled to the unit input to receive the dimmed mains voltage and capable of converting the received dimmed mains voltage to a dimmed LED current; at least one LED (31) coupled to output terminals (35, 36) of the lamp driver (32); and a bleeder circuit (200) coupled to the unit input for drawing a bleeder current (½) from the received mains voltage. The bleeder circuit (200) is an adaptive bleeder circuit comprising an intelligent control circuit (300), capable of determining a condition of the supplying mains dimmer. The control circuit (300) adaptively optimizes the bleeder current in relation to the condition of the supplying mains dimmer.
    • LED灯单元(100)包括:能够从供电电源调光器(1)接收暗电源电压(PCACV)的单元输入端(101,102); 具有耦合到所述单元输入端的输入端子(33,34)的灯驱动器(32),以接收所述调光的电源电压并且能够将所接收的调光的电源电压转换为变暗的LED电流; 耦合到所述灯驱动器(32)的输出端子(35,36)的至少一个LED(31); 以及耦合到所述单元输入的泄放电路(200),用于从所接收的电源电压中抽取泄放电流(1/2)。 泄放电路(200)是一种自适应泄放电路,包括智能控制电路(300),能够确定供电电源调光器的状态。 控制电路(300)相对于供电电源调光器的状况自适应地优化放电电流。
