The specific embodiment

Below in conjunction with Fig. 1 to 2 and embodiment the utility model is described in further detail.

In Fig. 1, E27 lamp holder 1 links to each other with civil power by common lamp socket, and civil power is by on the lead place in circuit plate 3.Circuit board 3 is integrated LED power circuit, acousto-optic control circuit and delay circuit, the photo resistance 7 of welding on it is exposed by the perforate 8 on lamp housing 2 walls, welds the position that Mike 9 on it adjusts to lamp housing 2 inwall perforates 10.The small-sized toggle switch 11 that is fixed on lamp housing 2 inwalls and exposes is connected with circuit board 3 by lead, in order to select shielding acousto-optic control function.Three

trimmer potentiometers

12,13,14 on the circuit board 3 are respectively that light sensitivity is regulated, the sound sensitivity is regulated and delay time is regulated.The user can regulate voluntarily with small-sized screwdriver after opening circuit.Circuit board 3 is connected by screw rod and nut with the integrated substrate 4 of LED, after the connection in the lump three draw-in grooves by lamp housing 2 inwall settings fix.String and weld 30 LED 5 and be connected with circuit board 3 on the integrated substrate 4 of LED by lead.Threaded lampshade 6 is rotated with lamp housing 2 and is threaded.

In Fig. 2, form capacity voltage dropping circuit by C1, R1, through the D1-D4 bridge full-wave rectifier 220V civil power is become DC voltage.Again through one the tunnel to be triggered at thyristor MCR that attitude or mask switch K1 close under the state by R11 resistance be that the LED power supply of 30 strings and series-parallel connection is lighted after the C2 filtering.R11 plays protection LED.R10 is the part of this LED power circuit equally, and effect is that the storage electric charge to capacitor C 2 is released fast when closing lamp, and LED extinguishes immediately behind the assurance powered-down, because resistance R 10 values are bigger, when connecting power supply, circuit power consumption is minimum.After R2 step-down, C3 filtering again, Dz voltage stabilizing, provide power supply through another road after the C2 filtering for the acousto-optic control circuit.Control principle is: with the TC4011BP digital integrated electronic circuit is core, and its integrated circuit is totally 14 pins, 7 pin ground connection wherein, and 14 pin connect positive source.5, the inputs of NAND gates of 6 inputs, 4 outputs are connected together and from photo resistance R _GInsert with the link of R3.When daytime, light was strong, R _GPresent less resistance, the input of this moment 5,6 is low level, and output 4 is high level, makes 8 pin be input as high level with switching tube D5.In stable state, electrochemical capacitor C4 goes up no electric charge, be that R7 goes up no-voltage, this moment, 12,13 pin were input as low level, and 11 pin are output as high level, promptly 9 pin are input as high level, because 8,9 pin all are high level, make 10 pin output low levels, receive the silicon controlled control utmost point through R8, led light source can not trigger the controllable silicon conducting, so can not worked.The size of regulating R3 can change the bright dark sensitivity of light, and R3 is big more, and sensitivity is low more.When light is dark, R _GPresent bigger resistance, at this moment, because 5,6 be input as high level, 4 output is low level just, and the height of 8 pin depends on the height of 3 pin output, and received by MIC if any voice signal this moment, then 1,2 pin present high level immediately, make 3 pin be output as low level, make 8 pin present low level through R9.This moment, high level appearred in 10 pin, made the MCR conducting with R8, and LED lights, and meanwhile, the high level of 10 pin charges to C4.After although LED is bright, because R _GChange in resistance makes 8 pin become high level again, but this moment owing to be filled with electric charge on the C4, make 12,13 input become high level, the high level output of 10 pin is kept by the low level output of 11 pin.Voltage on C4 discharge makes R7 drops to 12,13 during for low level, and low level is got back in the output of 10 pin, and the LED lamp is closed.Regulate the sensitivity of the big I change of R9 to voice signal, R9 is big more, and sensitivity is low more.Regulate R7 and can change lamp holding time when bright, R7 is big more, and it is long more to delay time.C5 plays the lotus root cooperation usefulness of voice signal, and C6, C7 have filter action, make DC voltage more stable.
