Method for realizing noise-free and stroboflash-free voltage regulation lamplight of lamp

Abstract

The invention discloses a method for realizing noise-free and stroboflash-free voltage regulation lamplight of a lamp, and relates to the technical field of lamp equipment. The method comprises the following steps: 1, installing a dimming signal acquisition circuit: installing the dimming signal acquisition circuit on one side of a single-chip microcomputer circuit; 2, installing a single-chip microcomputer circuit: installing the single-chip microcomputer circuit at one side of the voltage regulation circuit; and 3, installing a voltage regulating circuit: installing the voltage regulating circuit at one side of the driving circuit. In order to meet the condition that the darkest brightness of the lamp is adjusted to 0.01%, the signal analysis precision of the single-chip microcomputer circuit and the voltage signal output precision of the voltage adjusting circuit both adopt devices with the precision level of more than 12 bits so as to meet the dimming brightness requirement; the mode of adjusting the brightness of the lamp is that the single-chip microcomputer circuit adjusts the voltage signal to change the output voltage of the lamp driven by the driving circuit so as to adjust the brightness of the LED lamp.

Description

technical field [0001] The invention belongs to the technical field of lighting equipment, and in particular relates to a method for realizing noise-free and flicker-free voltage regulation of lighting. Background technique [0002] With the development and breakthrough of science and technology, people pay more and more attention to the quality of life and health. A healthy and comfortable lighting environment is often indispensable for people who pursue high-quality life. Therefore, dimming lamps are also Occupy a place in the lighting market. Most of the existing dimming lamps on the market use PWM technology to adjust the brightness of the light; , The stroboscopic and noise problems of lamps always exist. For people who pursue high-quality, healthy and comfortable life, this is precisely the most unacceptable place. Even if the problem of human sensory perception is excluded, the peak voltage generated based on the dimming method using PWM technology will cause damage...

AI Technical Summary

Problems solved by technology

Most of the existing dimming lamps on the market use PWM technology to adjust the brightness of the light; , the stroboscopic and noise problems of lamps always exist. For people who pursue high-quality, healthy and comfortable life, this is precisely the most unacceptable place

Even if the problem of human senses is excluded, the peak voltage generated by the dimming method based on PWM technology will cause damage to the LED lamp beads of the lamp

[0003] Therefore, it not only satisfies people's requirements for no flicker, no noise, and the brightness of the lighting adjustment reaches 0.01% brightness, but also does not damage the LED, which fully meets the requirements of LED working characteristics. It is still very popular in the existing market. rare
