Problems solved by technology

[0003] At present, many high-rise residential buildings under construction and already built have underground parking lots. These parking lots generally have multiple entrances and exits for personnel and vehicles. The underground parking lot has a large area and extremely poor light limit. 24-hour lighting; especially in the dead of night in the middle of the night, there are very few vehicles coming in and out, but the mains voltage is generally high, often as high as 240V or more, which not only causes huge energy waste, but also makes lighting lamps when the voltage is too high In the case of heat, it will reduce the service life of the lamp

Abstract

The invention discloses a multifunctional intelligent power-saving device which is characterized by having voltage stabilizing and undervoltage outputting functions according to the lightening function of an underground parking garage; a transformer is shifted in a contactless mode so as to avoid the fluctuation of a commercial power supply; when people enter the underground parking garage, normal voltage is output by a sensing probe and all illuminating lamps are turned on; and for a moment after the people leave from the underground parking garage, standard undervoltage is output and part of illuminating lamps is turned off so as to achieve the aim of saving power. The dead hours of after midnight each day can also be set as a regular energy-saving time period; a user can set over-voltage, undervoltage and normal voltage parameters by using keys; and meanwhile, the over-voltage, undervoltage and normal voltage parameters can be displayed through a liquid crystal display screen or are remotely set and controlled through a GPRS (General Packet Radio Service) wireless network.

Description

Technical field [0001] The invention relates to lighting energy-saving control, and is especially suitable for lighting energy-saving control of underground parking lots. technical background [0002] The development and effective use of energy is a worldwide issue, which is directly related to the survival and development of human beings. The non-renewable nature of resources determines that the focus of solving energy problems can only be the conservation and utilization of existing energy. Electric energy is one of the most widely used energy sources, and it is also the most important part of energy consumption. Power saving is the most important topic of energy saving. [0003] At present, many high-rise residential buildings under construction and already built have underground parking lots. These parking lots generally have multiple entrances and exits for personnel and vehicles. The underground parking lot has a large area and extremely poor light limit. 24-hour lig...
