Description

The electrodeless lamp of microwave sensing module

Technical field

The utility model relates to the electric source lighting technical field, specifically is the electrodeless lamp of a kind of microwave sensing module.

Background technology

At present, lighting and control switch can have multiple mode to select for use, and light fixture has incandescent lamp, fluorescent lamp etc. usually, but low because of the incandescent lamp light efficiency, power consumption is big, and fluorescent lamp is shorter useful life, and is convenient inadequately with hand switch, often because of the untimely waste electric energy of turning off the light.

Summary of the invention

The purpose of the utility model provides the electrodeless lamp of a kind of microwave sensing module of human body sensing illumination.

The utility model technical solution is: comprise electrodeless fluorescent tube, electric ballast; Microwave sensing module, buffer amplifier, switching circuit, delayer, triode current amplifier and relay and control circuit DC power supply; The built-in microwave oscillator radio frequency output of microwave sensing module is launched through loop aerial; The doppler frequency of the movable reflection of human body walking by the built-in detector detection signal of module through amplifier, peripheral buffer amplifier to the switching circuit of amplitude limiter circuit AM access module, delayer, triode current amplifier and relay; Relay contact inserts the power end of electric ballast, electric ballast output magnet ring coupled electrodeless fluorescent tube;

Wherein, buffer amplifier is by three not gate series connection input and output cross-over connection feedback biasing resistors of digital integrated circuit six not gates, and switching circuit through a not gate anti-phase shaping, inserts the monostable time delay device that is made up of two not gates by the detection of diode multiplication of voltage.

The utility model produces good effect: the microwave human sensing is opened electrodeless lamp illumination, and timing automatic is turned off the light, and the economize on electricity effect that turns off the light when you leave is grown, played to easy to use, the life-span.

Embodiment

With reference to Fig. 1,2; The utility model embodiment and embodiment: comprise electrodeless fluorescent tube 7, electric ballast 6; Microwave sensing module 1, buffer amplifier 2, switching circuit 3, delayer 4, triode current amplifier and relay 5 and control circuit DC power supply; The built-in microwave oscillator radio frequency output of microwave sensing module 1 is launched through loop aerial; The doppler frequency of the movable reflection of human body walking by the built-in detector detection signal of module through amplifier, peripheral buffer amplifier 2 to the switching circuit 3 of amplitude limiter circuit AM access module, delayer 4, triode current amplifier and relay 5; Relay contact connects the power end of electric ballast 6, electric ballast 6 output magnet ring coupled electrodeless fluorescent tubes 7.

Fig. 2; Microwave sensing module IC1 adopts model RD627; Its built-in microwave oscillator radiofrequency signal output is launched through loop aerial T; The doppler frequency that when Ambulatory Activity, reflects detects the output signal by the built-in detector of module and is amplified to switching circuit diode VD1, VD2 and capacitor C 1, the detection of C2 multiplication of voltage through amplifier, amplitude limiter circuit AM access module periphery by the buffer amplifier that digital integrated block IC2 adopts three not gate a, b, the c series connection cross-over connection feedback biasing resistor R1 of CD4069 to constitute; Be shaped as rectangular pulse signal through not gate d anti-phase; Triggering monostable time delay device to the resistance R 4 current limliting triode VT1 electric currents that are made up of the 5th not gate e, the 6th not gate f and resistance R 2, R3 capacitor C 4 through capacitor C 3 coupling amplifies and drives relay J; When not gate d was output as low level, the energising of its contact JK adhesive electric ballast made electrodeless lamp D build-up of luminance luminous.

Through the time-delay of 4 pairs of resistance R of monostable time delay device capacitor C, 3 discharges, contact JK discharges, and electrodeless lamp D outage is extinguished, and plays the economize on electricity effect that turns off the light when you leave.

Among the figure, the control circuit DC power supply is by the 6 incoming transport power supply AC220V step-downs of capacitor C 7 resistance R, through diode VD5 rectification and VD4 voltage stabilizing, and capacitor C 6 filtering supply control circuits, resistance R 5 is supplied with microwave sensing module power supply with capacitor C 5 further filtering.The diode VD3 protection triode VT1 that is connected in parallel on relay J coil two ends avoids the impact of reverse voltage.
