Programmable automatic constant LED illumination controller and control method thereof

Abstract

The invention discloses a programmable automatic constant LED illumination controller and a control method thereof. The controller comprises a remote controller, an information collector, a lighting controller and a dimming driving module. The method comprises the steps that the remote controller sends a dimming command to the lighting controller; the information collector collects external illumination brightness information and sends the information to the lighting controller; the lighting controller receives the dimming command, and generates a lighting control signal according to the dimming command and/or the external illumination brightness information; according to the lighting control signal, the dimming drive module is controlled to achieve LED dimming. The controller and the control method provided by the invention can conveniently change a dimming program (parameter) according to the actual needs of a user, collects the ambient brightness information and generates the lighting control signal, thereby realizing a function of automatically adjusting the LED lighting effect.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to a programmable automatic constant LED illuminance controller and a control method thereof. Background technique [0002] With the development of science and technology, LED lighting has entered the era of intelligence, and there are various control methods. For example, the traditional ways of controlling the brightness of lamps or light sources by wire include: thyristor dimming, 0-10v dimming, PWM dimming, DALI (Digital Addressable Lighting Interface, Digital Addressable Lighting Interface) dimming, etc. Among them, the intelligent lighting control system with DALI dimming as the control method is the most intelligent, and it is used in industrial places, office buildings, etc. to realize different lighting control methods. The wireless control methods include infrared remote control dimming, Bluetooth, WIFI, ZIGBEE and other 2.4G signal dimming. Through the wireless transmission t...

Problems solved by technology

[0003] There are two defects in the existing technology: on the one hand, the intelligent dimming control method ignores the function of the sensor and always runs through the pre-set program, but the user's use environment is not static, and the pre-set program is not very good. Automatically adapt to the current environment and make the most appropriate control

On the other hand, LED products with sensors cannot easily adjust the parameters of the installed lamps according to user needs, but in actual applications, it is often necessary to change the working procedures of the sensors according to changes in the installation environment to achieve different controls
