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 method and system for smooth dimming of lamps. The method for smooth dimming of lamps comprises the following steps: a controller receives brightness data of lamps; Multiple PWM dimming output signals; the brightness data is stored in a brightness database, the PWM dimming output signal is saved in a PWM dimming output signal database, and the brightness database is connected with the PWM dimming output signal database through a machine learning module , the two learn through training to achieve intelligent matching. The method and system for smooth dimming of lamps provided by the present invention are suitable for debugging intelligent lamps such as LED lamps. The steps are reasonable and the operation is convenient, which realizes smooth dimming of lamps, makes the dimming softer, and avoids the appearance of a cliff in light effect In the case of a formula mutation, the efficiency of dimming 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...
