LED Intelligent Dimming System

LED intelligent dimming system is an electrical accessory used to change luminous flux, adjust illuminance and make all kinds of new LED lamps achieve high-quality lighting effect. It can be widely used in hotel rooms, venues and exhibition halls.

Lighting creates a visual environment by illuminating specific objects or a wider range. It not only provides human visibility to the surrounding environment, but also creates the comfort, aesthetics and safety of the atmosphere of the lighting environment. The proposal of green lighting emphasizes the concept of energy conservation and environmental protection. The characteristics of LED, such as high efficiency, long life, no mercury harm, no infrared and ultraviolet radiation, rich color and easy control, make it an ideal light source in the field of green lighting

In addition to the functions of ensuring daily life, culture and entertainment, work and study, the modern intelligent building can also form different lighting scenes through the intelligent control of building lighting and the light and dark matching of different lighting circuits in different spaces, create a comfortable and elegant environmental atmosphere and enrich people's needs for different occasions; At the same time, by creating different lighting environment, it sets off the elegant artistic cultivation of residents.

Although dimming has been widely used, the service life of LED can be shortened due to excessive LED current, resulting in light attenuation and other problems, which seriously affect the lighting effect of LED. Led fault detection is generally manual patrol inspection without automatic detection function. LED lighting light attenuation and lamp damage lead to the overall illumination of the environment not reaching the lighting standard, so light attenuation compensation and automatic fault detection become an objective demand; Secondly, when the dimmer is used with traditional light sources, there are still some defects, such as reducing the efficiency of incandescent lamps and damaging the service life of fluorescent lamps.

If any LED device is to be made into a replacement light source or LED lamp, it needs a driver to realize dimming. Because LEDs are low-voltage DC sources, LEDs need electronic drivers to convert AC into usable and adjustable DC current.

The current flowing through the LED bulb determines the light output, and its brightness can be easily adjusted by controlling the energizing current of the semiconductor material layer pasted on the substrate. Dimming can reduce the working temperature of LED lamps and prolong the service life of LED lamps.

LED intelligent dimming system can be used for residential building lighting, art museum lighting, theater lighting, night scene lighting, intelligent building hotel lighting, commercial building lighting and office building lighting. As a lighting accessory used to change the luminous flux of electric light source and adjust the illuminance, it can be widely used in home lighting, theater stage, hotel guest room, venue exhibition hall and other occasions.

An LED dimming system consists of system unit, input unit and output unit. The input unit is responsible for transmitting external signals / commands to the system, such as intelligent panel, sensor, etc. The system unit supports the operation of the whole system, such as power module, etc. The output unit is responsible for receiving the signal transmitted by the input unit and performing corresponding operations, such as adjusting the light brightness, etc.
