Abstract

The present invention relates to the technical field of intelligent electronic equipment. By providing an energy-saving lamp module, it includes a power chip, a single-chip microcomputer, a plurality of CMOS switches and a plurality of LED lamps, and the power output end of the power chip is connected to one end of a plurality of CMOS switches. The other end of the switch is connected to a plurality of LED lamps respectively, and the signal control terminals of the single-chip microcomputer are respectively connected to a plurality of CMOS switches and the power supply chip; The first constant current, at the same time, the single-chip microcomputer sends PWM signals to a plurality of CMOS switches respectively, to control a plurality of CMOS switches to carry out PWM dimming to a plurality of LED lamps; The control signal is used to control the power supply chip to output a constant voltage and a second constant current, wherein the second constant current is smaller than the first constant current, thereby effectively saving electric energy and prolonging life.

Description

technical field

[0001] The invention relates to the technical field of intelligent electronic equipment, in particular to an energy-saving lamp module. Background technique

[0002] The existing lighting control adopts N-level control by PWM to realize multi-level adjustment of lighting, so as to meet the needs of users.

[0003] When the PWM is used alone for adjustment, the effective time of turning on the lamp is controlled by controlling the pulse signal, so that the lamp flashes with a certain duty ratio, which effectively saves power. However, because the light is controlled with a certain duty ratio A flashy microcontroller needs to consume a certain amount of power.

[0004] Therefore, in the prior art, although the brightness of the light can be adjusted steplessly by using the PWM mode alone to control the light, it still wastes power. Contents of the invention

[0005] The embodiment of the present invention solves the technical problem of power waste in the p...
