Abstract

The invention relates to the technical field of intelligent electronic devices and provides an energy-saving lamp module. The energy-saving lamp module comprises a power supply chip, a single-chip microcomputer, at least one CMOS switch and at least one LED lamp, wherein the power supply output end of the power supply chip is connected with one end of the CMOS switch, and the other end of the CMOS switch is connected with the LED lamp; the signal control end of the single-chip microcomputer is respectively connected with the CMOS switch and the power supply chip; the single-chip microcomputer is used for sending out a first control signal to the power supply chip at the first moment to control the power supply chip to output constant voltage and first constant current; meanwhile, the single-chip microcomputer sends out a PWM signal to the CMOS switch to control the CMOS switch to perform PWM dimming on the LED lamp; the single-chip microcomputer is also used for sending out a second control signal to the power supply chip at the second moment to control the power supply chip to output constant voltage and second constant current; the second constant current is smaller than the first constant current.

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...
