LED lighting fixture illumination induction control system for office buildings

Abstract

The invention discloses an LED lighting fixture illumination induction control system for office buildings. Each LED lighting fixture is connected with an LED controller. An illumination measurement device and an infrared sensor are connected to each LED controller. The illumination measurement devices are used for acquiring the light intensity of preset light areas of the corresponding LED lighting fixtures, and the infrared sensors are used for acquiring position information of personnel in an office building. Each LED lighting fixture includes an LED lamp, an LED light brightness adjustment device connected with the LED lamp, and a light beam angle adjustment device connected with the LED lamp, wherein the LED light brightness adjustment device is used for adjusting the input voltage of the LED lighting fixture, and the light beam angle adjustment device is used for adjusting the light beam angle of the LED lighting fixture. By adopting the system of the invention, LED lighting fixtures in an office building can be managed intelligently, human waste is reduced, real-time and closed-loop refined energy control is performed on lighting inside office buildings, and real-time variable-illumination light compensation is implemented to minimize power consumption of indoor lighting.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to an illuminance sensing control system for office building LED lamps. Background technique [0002] In energy consumption, lighting is the second largest consumption field after industrial energy consumption. With the acceleration of urban construction, more and more office buildings in the city will be put into use, and it can be expected that the electricity consumption for lighting will gradually increase. Therefore, research on energy-saving and environmentally friendly lighting systems will help save conventional energy and protect the environment. The 20% target of reducing GDP consumption during the "Eleventh Five-Year Plan" period proposed by the National Development and Reform Commission is of great significance. In cities, office buildings are important places for corporate offices. To meet the needs of office workers, LED lamps are installed in office buildings to ac...

Problems solved by technology

For the public areas of office buildings, it is difficult to turn off the lights when people leave. Most of them adopt the constant light mode. At night, the on-duty personnel in the office building are required to cut off the power, which not only increases the workload of the on-duty personnel, but also increases the lighting power consumption.
