Abstract

A lighting module power-saving control method in which a switching control loop (11) is installed in a lamp for outputting a high-frequency current output signal and a low-frequency current output signal, the length of a unit time is divided into multiple equal parts for enabling the power output loop (12) of the lamp to alternatively output a normal-consumption current and a power-saving current to the lighting module of the lamp subject to the control of the switching control loop (11), and the frequency of the supply of the normal-consumption current is not less than 16 times/second.
