Abstract

The present application belongs to the technical field of circuits and provides a light adjustment method, a light adjustment device, and a terminal device. The light adjustment method comprises: obtaining a current pulse width modulation signal; obtaining a current pulse width modulation signal; linearly transforming the pulse width modulation signal to obtain a linear signal corresponding to thepulse width modulation signal; nonlinearly transforming the linear signal to obtain a dimming signal corresponding to the linear signal, and adjusting the brightness of an LED lamp by using the dimming signal. The method can effectively reduce the pause of light changes during a PWM dimming process, and effectively improve the softness of the light changes.

Description

technical field [0001] The present application belongs to the field of circuit technology, and in particular relates to a lighting adjustment method, a lighting adjustment device and terminal equipment. Background technique [0002] With the development and promotion of the Internet of Things and smart homes, there are more and more demands for light source dimming, and the quality requirements for dimming are also getting higher and higher. Light-emitting diodes (referred to as LEDs) have many advantages, among which easy dimming and easy color adjustment are one of the main advantages of LEDs. Therefore, LED light sources gradually replace traditional light sources and become the main force in today's lighting market. [0003] At present, LED light sources are usually dimmed based on pulse width modulation (Pulse Width Modulation, PWM) technology, the principle of which is to adjust the voltage value by adjusting the duty cycle of the PWM signal. However, when using the ...
