Abstract
The present invention primarily relates to a method for initiating and controlling a lighting equipment by detecting and determining through an algorithm whether a flicker of light may occur during the period of initiating or dimming the lighting equipment. The method further calculates to obtain a current compensation ratio that the current level need be elevated to prevent the occurrence of flicker and performs a real-time compensation for the electrical current, when necessary. The method according to the invention will initiate the lighting equipment at an electrical current level used during a previous stable operation of the lighting equipment, so as to further prevent the occurrence of flicker of light during the initiation of the lighting equipment and achieve the energy saving purpose.
