Problems solved by technology

However, because the lamp itself cannot be connected with an external dimming line on the wiring, the dimming methods of LED dimming lamps on the market are mainly: 0-10V or 1-10V dimming, thyristor dimming, PWM dimming, and secondly Need to match the corresponding dimmer, or need to match the gateway, sensor, remote control, etc., or external power supply to achieve dimming, the circuit needs to be modified when replacing, and it is not easy to use

Abstract

The invention relates to a method for realizing LED lamp dimming by using a switch, an LED lamp dimming system and an LED lamp. The method comprises the following steps of reading a stored dimming signal data value; judging whether the dimming signal data value is a reset value or not; if yes, outputting a first dimming signal which changes circularly according to a preset change rule to a drivingcontrol circuit so that the driving control circuit outputs a corresponding driving current to enable the brightness of the LED lamp to change circularly according to a certain rule; judging whethera switching signal is received or not; if so, storing the dimming signal data value corresponding to the first dimming signal output at the moment and keeping the dimming signal data value unchanged;a second dimming signal corresponding to the stored dimming signal data value being outputted to the driving control circuit so that the driving control circuit outputs a corresponding driving currentto enable the LED lamp to emit light with corresponding brightness; judging whether a reset signal is received or not; and if so, setting the stored dimming signal data value as a reset value. The LED lamp can be directly replaced for use without changing the wiring mode of the LED lamp, cost is low, and dimming is easy and convenient.

Description

technical field [0001] The invention relates to the field of LED lighting control, and more specifically relates to a method for realizing dimming of an LED lamp by using a switch, a dimming system for the LED lamp and an LED lamp. Background technique [0002] DLC (Design Lights Consort) V5.1 version requires LED lamps to have dimming function. However, because the lamp itself cannot be connected with an external dimming line on the wiring, the dimming methods of LED dimming lamps on the market are mainly: 0-10V or 1-10V dimming, thyristor dimming, PWM dimming, and secondly It needs to be equipped with a corresponding dimmer, or needs to be equipped with a gateway, sensor, remote control, etc., or an external power supply to achieve dimming. When replacing, the circuit needs to be modified, and it is not easy to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for dimming an LED lamp by using a swi...
