    • A lighting device (132) includes a circuit having a power supply and a plurality of light emitting diodes (120) connected in series with the power supply. The plurality of light emitting diodes (120) includes at least two groups of series-connected light emitting diodes, the groups of series-connected light emitting diodes being connected in series. A different optically isolated field effect transistor (U3-U5) is connected in parallel with each group of series-connected light emitting diodes, for selectively shunting around the group of series-connected light emitting diodes. A different capacitor (C8-C10) can also be connected in parallel with each group of series-connected light emitting diodes. A controller (U2) is connected to a gate of each of the optically isolated field effect transistors (U3-U5) for selectively turning the optically isolated field effect transistors (U3-U5) on and off. Thus, the controller U2 is electrically isolated from the power supply by the optically isolated field effect transistors (U3-U5). The light emitting diodes (120) can be driven and controlled using pulse width modulation methods.
    • 一种照明设备(132)包括具有电源和连接在与电源串联发光二极管(120)的多个电路。 的发光二极管(120)多个包括至少两组串联连接的发光二极管,串联连接的发光二极管的组串联连接。 一种不同的光学隔离场效应晶体管(U 3 -U 5)并联连接与各组串联连接的发光二极管,该组串联连接的发光二极管的周围选择性地分流。 不同的电容器(C 8 -C 10)因此,可以并联连接各组串联连接的发光二极管。 控制器(U2)被连接到每个所述光隔离的场效晶体管的栅极(U 3 -U 5),用于有选择地打开所述光隔离的场效应晶体管(U 3 -U 5)和关断,因此, 控制器U 2是从由光隔离场效应晶体管的电源(U 3 -U 5)电隔离。 发光二极管(120)可被驱动,并使用脉冲宽度调制方法来控制。
