System and method with common and emergency LED (light emitting diode) intelligent illumination

Abstract

The invention relates to a system with common and emergency LED (light emitting diode) intelligent illumination, which is composed of an AC-DC (alternating current-direct current) power supply module, a standby power supply charging / discharging module, a main power supply detection module, a standby power supply, LED bead driving modules, a core controller, a common illumination control switch and LED bead string modules, wherein the AC-DC power supply module mainly realizes the conversion from a main AC power supply to a DC power supply; the standby power supply charging / discharging module realizes charging / discharging control on the standby power supply under the control of the core controller; the main power supply detection module mainly realizes state detection on the main AC power supply and reflects a detection result to the core controller; each LED bead driving module is controlled by the core controller and realizes constant current source driving of LED bead illumination; and the core controller realizes monitoring and control on the state of the whole system, and performs corresponding control according to the state of the main AC power supply, the state of a common illumination switch and the full state of a storage battery so as to realize automatic switching between common illumination and emergency illumination and charging / discharging control on the storage battery.

Description

technical field [0001] The present invention relates to a system and method for both ordinary and emergency LED intelligent lighting. Background technique [0002] In daily life, lighting is generally divided into ordinary lighting and emergency lighting. Ordinary lighting is usually installed on the ceiling, while emergency lighting is generally installed at key passages. Ordinary lighting is used for general lighting under normal conditions. In the case of abnormal power failure, the general lighting will no longer work, and the emergency lighting will start to work and provide the necessary lighting for the emergency evacuation of the personnel in the area. [0003] The existing general lighting is basically based on traditional ordinary fluorescent lamps, especially in public indoor places such as office buildings, shopping malls, factories, and teaching buildings. [0004] Existing emergency lighting is used in various public areas. It can be mainly divided into indepe...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a system and method with common and emergency LED intelligent lighting, which mainly solves the technical problems in the above-mentioned prior art. The system is separated, the emergency lighting cannot be evenly distributed in the entire lighting area, and it cannot be used as general lighting in the non-emergency state, and it is easy to be damaged in an emergency state such as an earthquake. It solves the problems of waste of lighting resources, high construction costs, and high maintenance costs under normal conditions. The duration of emergency lighting cannot be intelligently adjusted and extended according to the backup power supply (battery)
