Abstract

The invention discloses a lighting security device for a public area in a urban, which comprises an AC / DC conversion module, a DC back up power source, an LED lamp module and an intelligent detection controller , wherein the input end of the AC / DC conversion module is connected with commercial power, and the output end is respectively connected with the DC back up power source and the input end of the LED lamp module; and the intelligent detection controller is powered by the DC back up power source and is provided with an input end connected with the commercial power and the AC / DC conversion module, and an output end is respectively connected with a first control switch, which is used for controlling on / off of the output end of the DC back up power source, and a second switch, which is used for controlling the on / off of the input end of the LED lamp module. The lighting security device reduces inversion links of conversion of the direct current to the alternate current; meanwhile, as the LED lamp uses the direct current, the inversion wastage and conversion loss is reduced; the cost is greatly reduced; and the reliability of a system is enhanced.

Description

technical field [0001] The invention relates to a lighting protection device for urban public areas. Background technique [0002] At present, people have high requirements for the lighting of urban public areas. Man-made sabotage and power accidents cause large areas of lights to be extinguished in the city, which will bring great hidden dangers to urban safety. How to ensure the continuous normal operation of the lighting system in urban public areas , is an important topic in front of us, and it is also one of the important tasks to ensure the social stability of the city and the safety of citizens, and to build a harmonious society. [0003] At present, the lighting safety protection devices in the market basically use UPS or EPS as backup power supply. After the mains power is interrupted, UPS or EPS will continue to supply power for lamps. [0004] There are many types of UPS, figure 1 It shows a working principle block diagram of an existing power frequency on-line ...
