Description

An energy-saving control system for LED lighting in an underground garage

technical field

The utility model belongs to the application field of LED lighting, in particular to an energy-saving control system for LED lighting in an underground garage.

Background technique

At present, in order to prevent accidents in the underground garage, the lights are always on 24 hours a day. This not only consumes a lot of power, but also causes frequent failures of the entire lighting system and greatly increases maintenance costs. Therefore, the general situation of many underground garage lighting is as follows: low light efficiency, insufficient illumination, poor safety; high energy consumption, fast light decay, low color rendering; unable to start when the voltage is unstable, frequent replacement, and heavy workload; The thermal effect is large. The energy consumption of lighting system in modern buildings has been as high as 35%. The concept of "green" lighting has been introduced in the construction industry. The central idea is to maximize the use of natural light sources, set the clock for automatic control, and use illuminance sensing and motion sensors. At present, the underground garage mainly adopts two control methods of infrared sensor and radar sensor detection to intelligently control the lighting of the underground garage, but due to the limitations of the detection of these two methods, many sensors need to be installed in the underground garage, so from the perspective of cost and installation , which is more troublesome. The utility model proposes an energy-saving control system for LED lighting in an underground garage, which uses an infrared camera to detect the dynamic range in the garage to realize intelligent adjustment of the brightness of the LED light, thereby improving various disadvantages existing in the current underground garage lighting system.
