    • A discharge lamp system includes a discharge lamp, a power source, a converter, a lamp state signal detection module and a controller. The power source provides a DC power. The converter converts the DC power into a current required by the discharge lamp. The lamp state signal detection module receives a lamp state signal and outputs a lamp state detection signal. The controller processes the lamp state detection signal and a given synchronization signal to generate an average lamp current signal and a pulse current signal, and then processes the average lamp current signal and the pulse current signal to generate a control signal. The controller performs current control of the discharge lamp through the converter according to the control signal. Furthermore, a method for controlling a discharge lamp is also disclosed herein.
    • 放电灯系统包括放电灯,电源,转换器,灯状态信号检测模块和控制器。 电源提供直流电源。 该转换器将直流功率转换成放电灯所需的电流。 灯状态信号检测模块接收灯状态信号并输出​​灯状态检测信号。 控制器处理灯状态检测信号和给定的同步信号以产生平均灯电流信号和脉冲电流信号,然后处理平均灯电流信号和脉冲电流信号以产生控制信号。 控制器根据控制信号通过转换器对放电灯进行电流控制。 此外,本文还公开了一种用于控制放电灯的方法。

    • An electric pruner includes a housing, a motor accommodated within the housing, a transmission mechanism, a movable blade, and a fixed blade extending from the front end of the housing. The fixed blade is fixedly mounted on the housing, and the movable blade is rotatably connected to the fixed blade via a shaft and driven by the motor via the transmission mechanism. A locking device manually operable by the user is arranged n the shaft for locking the movable blade, the locking device being switchable between a first position where the movable blade is locked to stay connected with the transmission mechanism and a second position where the movable blade is releasable from the transmission mechanism. Thus, the replacement of the movable blade is very simple and convenient.
