    • A control system for controlling the illumination intensity of a gas discharge lamp to provide only necessary illumination and thus conserve power consumption. The control system has a daylight harvester which produces a control signal related to the available light within a given area. The control signal is conducted to a voltage controlled oscillator which, in turn conducts an oscillating signal to a frequency controlled ballast transformer that effectively drives the gas discharge lamp controlling the illumination intensity and energy consumption. The control system alternatively comprises a remote signal receiver for use alone or in addition to the daylight harvester. The control system with a remote signal receiver is controllable using a remote signal generator such as laser pointer. The remote signal receiver allows the user to control the illumination intensity of a gas discharge lamp from the area being illuminated.
    • 一种用于控制气体放电灯的照明强度以仅提供必要的照明并因此节省功耗的控制系统。 控制系统具有日光收割机,其产生与给定区域内的可用光线相关的控制信号。 控制信号被传导到压控振荡器,该压控振荡器又将振荡信号传导到频率控制的镇流变压器,其有效地驱动气体放电灯来控制照明强度和能量消耗。 控制系统可选地包括用于单独使用或除了日光收割机之外的远程信号接收器。 具有远程信号接收器的控制系统可以使用诸如激光指示器的远程信号发生器来控制。 远程信号接收器允许用户从照明区域控制气体放电灯的照明强度。
