Problems solved by technology

[0004] In the prior art, the dimming of LED lamps uses a dedicated driver chip for PWM dimming. Although the dimming can achieve a relatively high gray scale and a relatively high refresh rate, the dimming form is relatively fixed and single, and the brightness data changes suddenly. When the light effect changes, it will also show a cliff-like jump

Abstract

The invention discloses a lamp smooth dimming method and system. The lamp smooth dimming method comprises the following steps that a controller receives lamp brightness data; the controller configuresPWM dimming output signals according to the received brightness data, and multiple paths of PWM dimming output signals are configured between adjacent brightness; and the brightness data is stored ina brightness database, the PWM dimming output signals are stored in a PWM dimming output signal database, the brightness database establishes connection with the PWM dimming output signal database through a machine learning module, and the brightness database and the PWM dimming output signal database realize intelligent matching through training learning. The lamp smooth dimming method and system provided by the invention are suitable for debugging of intelligent lamps such as LED lamps, the steps are reasonable, the operation is convenient, smooth dimming of a lamp is realized, dimming is softer, the situation of cliff-type sudden change of the lighting effect is avoided, and the dimming efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of lamp detection and relates to a method and system for smooth dimming of lamps. Background technique [0002] LED lighting fixtures are the general term for LED lighting fixtures, which refer to appliances that can transmit light, distribute and change the light distribution of LED light sources, including all parts required to fix and protect LED light sources except for LED light sources, as well as connections to power sources Required wiring accessories. [0003] The LED lamp test is mainly to test the color, brightness and smoothness of the color change of the lamp. Due to different suppliers, there are differences in the channel brightness and mixed light effect of the chip of the LED lamp. In addition, due to the external factors of the use site, the illumination effect of the LED lamp will also be different. Therefore, it is necessary to determine the corresponding setting parameters of the LED l...
