    • A series arrangement of LED loads (LP1-LP4) is coupled between output terminals of a rectifier having its input terminals coupled to a mains supply supplying a low frequency AC voltage. Control means render the LED loads conductive one by one, when the amplitude of the supply voltage increases, and non-conductive one by one when the amplitude of the supply voltage decreases. The first LED load (LP1, LP2) has a forward voltage that is substantially higher than that of the other LED loads. As a consequence, the LED utilization is comparatively high, thus allowing the LED loads used in the series arrangement to be comparatively cheap.
    • LED负载(LP1-LP4)的串联布置耦合在整流器的输出端子之间,其输入端子耦合到提供低频AC电压的电源。 当电源电压的幅度增加时,控制装置使LED负载一个接一个,当电源电压的幅度减小时,LED逐一导通。 第一个LED负载(LP1,LP2)具有远高于其他LED负载的正向电压。 因此,LED利用率相对较高,从而允许串联装置中使用的LED负载相当便宜。
