Intelligent lighting circuit and intelligent lighting system for underground garages and lighting control method

Abstract

The invention relates to the field of intelligent lighting, and discloses an intelligent lighting circuit and an intelligent lighting system for underground garages and a lighting control method, which solve the problem existing in the prior art that a great deal of electric energy is consumed by the extensive management method adopted for managing the electricity consumption of lighting in an underground garage. A singlechip, an illumination detection circuit, an infrared sensor, a sound sensor and the like are designed in the intelligent lighting circuit in the prior art; the current intensity of ambient light in an underground garage is detected in real time by the illumination detection circuit, and the infrared sensor and the sound sensor are utilized to respectively detect whether human beings are present or sound exists; if no human beings or sound is detected, then the singlechip outputs the output of a PWM (Pulse-Width Modulation) wave control drive circuit corresponding to aduty cycle according to the current intensity of ambient light, i.e., at the moment, the brightness of lamps is only controlled by the current intensity of ambient light in the garage; and if human beings or sound is detected, 100 percent of PWM waves are outputted by the control drive circuit, so that the lamps work in a rated state.

Description

technical field [0001] The invention relates to the field of intelligent lighting, in particular to an intelligent lighting circuit, system and lighting control method for underground parking garages. Background technique [0002] With the improvement of living standards, cars are becoming more and more popular in people's lives. With the increase in car ownership, the demand for surface parking lots and underground garages is also increasing. The underground garage is widely used in modern civil buildings and office buildings because it is arranged underground and does not occupy ground resources, making the overall environment beautiful and harmonious. However, the biggest disadvantage of the underground garage compared to the surface parking lot is the poor light and needs to rely on artificial lighting. [0003] At present, the power consumption of underground garage lighting is based on an extensive management method. The lights are all turned on 24 hours a day, and t...
