Problems solved by technology

The LED light control circuit is equipped with a remote control receiving device, and the LED light can be dimmed step by step or steplessly dimmable through the remote control. The disadvantage is that one LED light needs to be equipped with a remote control, resulting in a large number of remote controls and troublesome management. , the cost is also high
However, this method can only provide 4 levels of adjustable brightness of LED lights, and the switch action has a time requirement

Abstract

A LED lamp wall control dimming method is provided. Dimming is realized through an LED lamp single-fire line dimming circuit composed of a brightness wall control unit and a brightness adjustment driving unit. When the brightness needs to be adjusted, the brightness wall control unit controls to change the phase shift angle of the output voltage waveform of the single fire line to transmit the brightness control signal. In the brightness control signal, the brightness level is expressed by the number of successive single-phase sinusoidal half-waves with a specific phase shift angle. The brightness adjustment driving unit changes the brightness of the LED lamp according to the brightness level in the brightness control signal. When the brightness control signal is sent out by the brightnesswall control unit, the number of half-waves with the same phase shift angle continuously output by the output terminal of the single fire line is the brightness level of the brightness control signal. The LED lamp dimming method can be used for the replacement and upgrading of a common single-fire-line control lighting lamp.

Description

[0001] The patent application for this invention is a divisional application, the original application number is 201510229502.6, the application date is May 8, 2015, and the invention name is a LED lamp wall control dimming method. technical field [0002] The invention relates to a lighting lamp technology, in particular to a LED lamp wall control dimming method. Background technique [0003] Due to the nonlinear characteristics of LED lamps, the brightness of LED lamps cannot be realized by adjusting the voltage. [0004] When using a controllable constant current source to adjust the brightness of the LED lamp, the change of the working current will cause the color shift of the LED lamp. At the same time, the load current of the LED lamp becomes very low under low brightness, which will make the controllable constant current source The lower the efficiency and the higher the temperature rise, the greater the power consumption on the driver chip will be, which will damage ...
