Abstract

The utility model relates to an induction light-emitting diode (LED) ceiling lamp, which is formed by connecting a lampshade, a circuit board, a heating panel, an inductor, a power supply with a chassis in sequence. The induction LED ceiling lamp is characterized in that the inductor comprises a capacitance voltage reduction circuit, a microwave induction controller and a four-negative and gate integrated circuit, wherein the capacitance voltage reduction circuit is connected with the microwave induction controller, and the microwave induction controller is connected with the four-negative and gate integrated circuit in series. The microwave induction controller comprises a loop antenna and a microwave triode; the loop antenna is fixedly connected with one side of the microwave triode; and three pins of the microwave triode are connected with the four-negative and gate integrated circuit in series. The induction LED ceiling lamp has the advantages that the inductor is accessed to an LED lamp, thus, not only is the energy saving and emission reduction advantage of the LED lamp performed, but also people can conveniently go out at night, and moreover, an induction lamp cannot be turned on under an unmanned state, and thereby, the electric energy is further saved, and the service life is also prolonged.

Description

A kind of induction LED lamp affixed to the ceiling

Technical field

The utility model relates to a kind of lighting, especially a kind of microwave induced LED lighting.

Background technology

Because global warming, the continuous expansion of greenhouse effects, energy-saving and emission-reduction more and more are familiar with by popular, aspect illumination, common incandescent lamp is heated to incandescent state with the filament energising, utilizes heat radiation to send the electric light source of visible light.Most of incandescent lamp can change into useless heat energy to 90% in the consumed energy, and only being less than 10% energy can become light.Such structure had not only been taken electricity but also contaminated environment.So general now employing LED lamp replaces original incandescent lamp, the LED light fixture has the advantage of energy-conserving and environment-protective, can alleviate the diffusion of greenhouse effects effectively.Yet the sense light in the corridor generally all is an incandescent lamp now, and how designing a kind of induction type LED lamp is the problem that we should solve.

The utility model content

The purpose of this utility model is to provide a kind of induction type LED lamp to answer incandescent lamp to replace heritage.

The utility model is achieved in that a kind of induction LED lamp affixed to the ceiling, is connected to form successively by lampshade, wiring board, heat sink, inductor, power supply and chassis; It is characterized in that: described inductor comprises capacity voltage dropping circuit, microwave induction controller and four NAND gate integrated circuits; Capacity voltage dropping circuit is connected with microwave induction controller, and microwave induction controller is connected with four NAND gate integrated circuits.

Described microwave induction controller is made up of loop aerial and microwave triode; Described loop aerial and microwave triode one side are affixed, and three pins of microwave triode are connected with four NAND gate integrated circuits.

The beneficial effects of the utility model insert the LED lamp with inductor, not only brought into play the energy-saving and emission-reduction advantage of LED lamp but also can be convenient for people to the trip at night, and sense light can not open under unmanned state, have further saved electric energy and have also prolonged service life.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

A kind of induction LED lamp affixed to the ceiling is connected to form successively by lampshade 1, wiring board 2, heat sink 3, inductor 4, power supply 5 and chassis 6; Described inductor 4 comprises capacity voltage dropping circuit 41, microwave induction controller 42 and four NAND gate integrated circuits 43; Capacity voltage dropping circuit 41 is connected with microwave induction controller 42, microwave induction controller 42 is connected with four NAND gate integrated circuits 43, adopt capacity voltage dropping circuit 41 electric main can be converted to low-voltage direct, thereby can make LED lamp operate as normal, and this capacity voltage dropping circuit 41 not only the powered microwave induction controller 42 but also the four NAND gate integrated circuits 43 of powering.

Described microwave induction controller 42 is made up of loop aerial 421 and microwave triode 422; Described loop aerial 421 is affixed with microwave triode 422 1 sides, and three pins of microwave triode 422 are connected with four NAND gate integrated circuits 43.Described loop aerial 421 had both been made transmitting antenna and also can have been received by human body and move and the echo that reflects.

In use, to have detected the people movable in monitoring range when the loop aerial 421 of microwave induction controller 42, F1 output high level by microwave triode 422 and four NAND gate integrated circuits 43 makes F2 conducting output low level jointly, becomes high level after F3, F4 are anti-phase, make bidirectional triode thyristor BCR conducting by R5, light LED, when the people left monitoring range, microwave induction controller 42 quit work, by four NAND gate integrated circuits 43 bidirectional triode thyristor BCR is ended, LED extinguishes.
