Abstract
A sensing device, for controlling an LED lighting equipment, and more especially for electrical connection with at least one LED lighting equipment that can be driven by a DC power supply, is disclosed. The sensing device, which can be supplied with an external DC power source, comprises a control module, a signal adjusting unit, an object detecting unit, and a manual time-delay adjustor. The control module can send a control signal train of PWM or PFM to the signal adjusting unit, which will in turn send an amplified signal train of PWM or PFM to the LED lighting equipment, so as to control the illuminating level of the equipment. Thus, the problems of the conventional light modulators, resulting from the use of an AC power supply, can be alleviated. Also, the associated cost of the equipment can be reduced.
