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 an LED ceiling lamp realizing automatic light modulation through human body induction. The LED ceiling lamp comprises an AC-DC switch power supply, a DC-DC converter, a UPS battery pack, an electronic switch, a control circuit and an LED lamp bead. According to the invention, the LED ceiling lamp realizes the automatic light modulation through the human body induction due to additional design of the control circuit, the UPS battery pack and the electronic switch with a function of preferential connection with commercial power. The control circuit can control output of illumination light through detecting whether pedestrians exit in an illumination area or not, the electronic switch has a function of preferential connection with the commercial power and supplies power to the LED lamp bead through the commercial power, and in case of such conditions as sudden power failure and the like, the UPS battery pack which is already charged in advance can also be taken as an emergency power supply. Therefore, the LED ceiling lamp has comprehensive functions and is convenient and practical.

Description

technical field [0001] The invention relates to a lamp, in particular to an LED dome lamp which realizes automatic dimming through human body induction. . Background technique [0002] Dome light 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 multifunctional dome lights 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 lamps as lamp beads. Even if LEDs are used as lamp beads, they do not have UPS function, and those with dimming function 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, b...
