Abstract
The present invention provides a circuit for intermittently illuminating a light-emitting device. The present invention comprises a power input terminal coupled to receive electrical power, a light-emitting device; a switch having a first end connected with the power input terminal, and the switch having a second end which provides a switched electrical power to a light-emitting device; a cyclic pulse signal generator generating at least one cyclic pulse signal where a duty cycle and a frequency thereof are adjustably utilized to control the switch. The circuit for intermittently illuminated light-emitting device of the present invention can generate more than one cyclic pulse signal and control more than one switch, a switch can also be controlled by more than one cyclic pulse signals. Besides, those cyclic pulse signals have respective phases, thus, the operation timing of each switches is interlaced.
