Description of drawings of the present utility model is as follows:

Fig. 1 is an overall lamp header structure installation diagram.

Fig. 2 is a circuit block diagram.

Fig. 3 is circuit theory diagrams.

Operation principle of the present utility model is: referring to accompanying drawing, suppress insulation lamp holder 1, loam cake 3, wiring board 5, housing 6 and bulb tail 7 by mould, assembling respectively then, lamp holder 1 can adopt the bayonet socket form, also can adopt the screw socket form, and bulb tail 7 can, also available bayonet socket form or screw socket form, if bulb tail 7 need not, housing 6 directly can be fixed on required part, and pass through civil power; If adopt, can be installed in arbitrarily on bayonet socket or the screw socket.The entire circuit trend of work is such: when daytime, light was strong, photo resistance R8 detects this environment, shows low-resistance, and power Vcc is after R3 and R8 dividing potential drop, 13 pin input low levels among the U1:D, 11 pin output high level, 4 pin output low levels among the U1:B thus, (its 5 pin is a high level, audible signal was accepted by HB, 4 pin output high level, but because resistance R 5 output low levels, T1, T2 still end.) 10 pin output low levels among the U1:C, T1 and T2 are in cut-off state, no signal output, so T3 also is cut-off state, switch is in off-state, and bulb does not work.To evening, when light was more weak, photo resistance R8 was high resistant, and 13 pin are high level among the U1:D, and 12 pin are low level, and when noiseless triggering, 5 pin are high level among the U1:B, 4 pin low levels, and T1, T2 end.When the sound, Electret condenser microphone HB receives acoustical signal, reach 1 pin among the U1:A, 2 pin through potentiometer U1, capacitor C 1, at anti-phase (low level) signal that 3 pin obtain amplifying, then 5 pin are low level among the U1:B, 4 pin output high level among the U1:B, at this moment owing to 11 pin output low levels among the U1:D, 10 pin are exported two road 50HZ square waves among the U1:C, and one the road to drive circuit T1 and T2, and another road is to diode D3 and capacitor C 3.Since 4 pin output high level among the U1:B, capacitor C 5 chargings, thus controllable silicon T3 voltage raises gradually, plays the slow start effect, after the timing, and 4 pin output low levels among the U1:B, 10 pin output low levels among the U1:C, T1, T2 and T3 are in cut-off state.

In drive controlling switching circuit 6, adopt I state as shown in Figure 3, then bulb L exports former power and reduces half, if adopt the II state, then to export former power constant for bulb L, in addition, control of bright time of lamp (second) is by the t=R6C5 decision, and the reception amplification of acoustical signal is controlled by potentiometer U1, these all can according to circumstances be selected by the user, and potentiometer U1 regulates voluntarily.

The utility model has the advantages that:

1, circuit adopts a slice integrated package and a small amount of element, and with being connected as a single entity of switch, with low cost, stable performance, self power consumption is the microwatt level.

2, because being provided with slow-starting circuit, so the curent change of bulb increases gradually, having avoided thus the big electric current of cold conditions to the impact of filament, thereby prolonged bulb self life-span.

3, because having adopted the bright timing circuit of lamp and acoustic control conditioned circuit, so the user can select and debugging according to condition.
