Power failure control device used for socket lamp

Abstract

The invention discloses a power failure control device used for a socket lamp. The power failure control device comprises a lamp body plug, a voltage conversion unit, a control unit and an LED lamp which are connected in sequence. The power failure control device further comprises a power detection unit a power failure execution unit. The power detection unit is connected with the control unit. The power failure execution unit comprises a first capacitor, a first resistor, a triode, a second resistor and a relay. One end of the first capacitor is connected with an output end of the control unit, and the other end of the first capacitor is connected with a base electrode of the triode through the first resistor. A collector electrode of the triode is connected with one end of the relay, and the other end of the relay is connected with a voltage end of the circuit. An emitter electrode of the triode is connected with the second resistor and then is grounded. The power detection unit is used for detecting the power in the circuit. The power failure control device has the advantages that the structure is simple, a power failure can be rapidly realized, the power failure is more flexible and automatic, the efficiency of the device is higher, and the manual turning off mode is not needed any more.

Description

technical field [0001] The invention relates to a power-off control device for a socket lamp, which belongs to the technical field of lamps. Background technique [0002] The lighting industry is a daily consumable. With the progress of my country's economy and society, the emergence of new light sources such as fluorescent lamps, energy-saving lamps, and LEDs has brought about earth-shaking evolutions in lighting fixtures. Everything is working towards more energy saving, greener and environmental protection. The richness and multiple choices of light sources have also opened up a new page for the lighting industry. With the acceleration of China's urbanization process, city squares, traffic roads, newly built communities, home decoration, shopping malls and office buildings all need lighting decorations, and the demand for lighting products in urban construction will continue to increase. [0003] Because of this, the socket lamp is widely used in life. It is suitable f...
