Abstract
An auto-sensing dimming lamp guides ambient light to a sensor installed in a lamp cover and at a base through a light pipe. The auto-sensing dimming lamp automatically adjusts a light emission status of LED light sources according to the ambient light by a processor installed at the base. The processor includes a pass filter unit and a modulation unit, and the pass filter unit receives a detected signal waveform of the sensor and a driving voltage waveform of the LED light sources.
