    • A power supply is provided. The power supply includes a plurality of light emission units, a power source, a plurality of boards, a plurality of board resistors, and a feedback control unit. The light emission units are connected in parallel, and include a plurality of LEDs. The power source supplies a DC voltage to the light emission units. The boards have at least one light emission mounted thereon. The board resistors are disposed in each of the boards, and electrically connected to each other. The feedback control unit varies a current supplied from the power source, according to sum of the board resistors which are changed according to the number of connected boards.
    • 提供电源。 电源包括多个发光单元,电源,多个板,多个板电阻和反馈控制单元。 发光单元并联连接,并且包括多个LED。 电源为发光单元提供直流电压。 板上安装有至少一个发光体。 板电阻器设置在每个板中,并彼此电连接。 反馈控制单元根据根据连接的板的数量而改变的板电阻器的总和,改变从电源提供的电流。
