Abstract

A sound, light and time co-control energy saving lamp circuit, which mainly comprises a rectifier circuit, a controllable switch, a voltage divided filter circuit and a main control circuit comprised by a time based integrated circuit as the center. The utility model can not only realize that the sound, light and time are all under control, and is convenient and sanitary, but also that the long and the short of the sound control sensitivity and the time latency can be adjusted, the anti-interference ability is strong, the moment when the switch is turned on and the daytime do not cause mis-conduction, the static state barely consumes electricity, the assembly and debug is simple, the volume is small, and the cost is low, the illumination lamps made by the circuit is the perfect product for the renovation and regeneration of existed lamps with the same class.

Description

Hold concurrently during acousto-optic and control electricity-saving lamp

The utility model relates to a kind of new special lighting circuit for lamp, especially is suitable as the lighting that need not long-term bright lamp place.This class floodlight circuit that uses is nothing more than modes such as touch, acoustic control, infrared ray sensings at present.The useful discrete electronic component of wherein acoustic control formula constitutes, and useful four NAND gate Schmidt triggers are that main body constitutes.Though these modes all can reach the control purpose, its weakness is arranged respectively: the assembling of discrete component, the debugging cumbersome, the cost of four NAND gate is higher, the two disadvantage is that antijamming capability is relatively poor, usually misleads; The disadvantage of soft-touch control is healthy and convenient inadequately; Though the superiority that it is arranged of infrared technology, quiescent dissipation is higher, the assembling trouble, and manufacturing cost is higher.

The purpose of this utility model is to overcome above-mentioned weak point, and provide a kind of new energy-saving lamp circuit, its realization sound, light, time-delay is simultaneously controlled simultaneously, can and can make a kind of antijamming capability by force, dependable performance, sound controling sensitivity and delay time is adjustable, assembling and setting is simple, the new lamp circuit of static state power consumption hardly, cheap for manufacturing cost and safety and sanitation.

The utility model purpose is achieved in that being reached with the time-base integrated circuit by rectification circuit, gate-controlled switch, pressure filter circuit is that the governor circuit that the center constitutes is electrically connected according to certain rule.

After sealing in bulb in the phase line of civil power, insert the ac input end of rectifier bridge with zero line, gate-controlled switch is served as by a unidirectional thyristor, unidirectional thyristor inserts the dc output end of rectifier bridge as load, Comprehensive Control when be the acousto-optic of governor circuit of center formation that the trigger end of this thyristor is then accepted with time-base integrated circuit (hereinafter referred IC).Light-sensitive device inserts DC power supply by a resistance, and the dividing potential drop on the light-sensitive device is applied between the reset terminal and ground of IC.Its reset terminal is unlike the input of general NAND gate, and it has the effect that triggers the input control signal that overwhelms.Dividing potential drop on the light-sensitive device is along with the bright dark degree of light changes, daytime, dividing potential drop was very low, the low level on daytime is just being blocked the output of IC, make it to remain low level always, no matter whether the IC input has the signal input, thyristor is misleaded and cause bright lamp, even can not mislead yet in the moment of connecting switch or inserting plug.Only at light during very dark or night, because reset terminal has presented high level, " blockade " has been disengaged, and sound control signal just can work.Acoustic control device-microphone connects into DC power supply with a resistance string, and the tie point of the two inserts a base stage that is in the triode of Class B magnifying state by an electric capacity.The collector electrode of triode is connected to the input of IC.During the voiceless sound signal, the triode C utmost point is that the input end of IC is in high level, in case the moment sound control signal is arranged, the triode conducting, collector voltage reduces suddenly, and the IC trigger end obtains a negative pulse, this moment is as long as reset terminal is a high level, the output of IC just is high level, makes the thyristor conducting, and light is glittering.Sound controling sensitivity is regulated by the base biasing resistor of triode.After time control device---Resistor-Capacitor Unit is gone here and there mutually, insert DC power supply, the two interface inserts threshold values end and the discharge end of IC simultaneously.Discharge end is consistent with output level height all the time.After output was high level, discharge end also was a high level, and electric capacity can not discharge, and can only be recharged, the threshold values end is then monitoring the height of this electric capacity charging voltage, in case when the voltage on the electric capacity reaches 2/3 supply voltage, the output of IC just overturns and is low level, and light extinguishes.The time of this bright lamp can be regulated by the change and the size of the resistance of this capacitances in series.

Below in conjunction with drawings and Examples the utility model is further specified.
