Problems solved by technology

When no one enters the sensing area, the light does not turn on at all, and it turns on when someone enters the sensing area. If the installation location is not selected well enough, the sensing sensitivity is poor. Even if someone enters the lighting area, the light will not light up. ; In addition, because traditional emergency lights are often not used for a long time, the probability of battery damage is very high. Great inconvenience to people's daily life

Abstract

The invention discloses a UPS LED ceiling lamp for realizing dimming by human body induction, comprising an AC-DC switch power supply, a DC-DC convertor, a UPS battery pack, an electronic switch, a human body induction control circuit and an LED light source. By adding the human body induction control circuit, the UPS battery pack and the electronic switch with the function of priority connection with commercial power, the UPS LED ceiling lamp can achieve dimming by human body induction; the human body induction control circuit can control output of illumination light by detecting whether pedestrians are in a lighting area; the electronic switch has the function of preferentially connecting with the commercial power and supplies power to an LED lighting source through the commercial power; and when conditions such as sudden power outage and the like occur, the UPS battery pack which is fully charged previously can be taken as the emergency power supply, thus the UPS LED ceiling lamp has the advantages of all-round functions and being convenient and practical.

Description

technical field [0001] The invention relates to a lamp, in particular to a UPS LED ceiling lamp which realizes dimming by human body induction. Background technique [0002] Ceiling lamp is a lighting device placed on the ceiling. With the development of economy and society and the improvement of people's living standards, more and more beautiful and versatile ceiling lamps are used in living rooms, bedrooms, and corridors. Most of the stairs or aisle lights with human body induction use traditional white lights or fluorescent lights as light sources. Even if LEDs are used as light sources, they do not have UPS functions, and those with dimming functions are even rarer. When no one enters the sensing area, the light does not turn on at all, and it turns on when someone enters the sensing area. If the installation location is not selected well enough, the sensing sensitivity is poor. Even if someone enters the lighting area, the light will not light up. ; In addition, becaus...
