发明名称 Automatic dimmer cutout for arc lamp of fiber optic light source
摘要 A control circuit and method is provided to automatically cut out a dimmer circuit from a high intensity light source until the light source has first been triggered and turned on at a high intensity level with the required high voltage. After an initial high illumination occurs a dimmer control circuit is electronically cut into the light circuit and a dimmer control knob, connected with a potentiometer, may then be used to raise or lower the illumination of the high intensity lamp. Thus, the high intensity lamp will be turned on regardless of the position of the dimmer control. Without the control circuit, the high intensity lamp would not trigger if the control knob was at a low intensity setting.
