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

Fig. 1 is the electrical schematic diagram of sound of the present utility model, light double-control lamp lamp holder.

Fig. 2 is the electrical schematic diagram of another kind of sound of the present utility model, light double-control lamp lamp holder.

Fig. 1 has described an embodiment of the present utility model.Comprise time-base integrated circuit IC2(model NE555 in the circuit), microphone M, bidirectional triode thyristor SCR, triode V21, diode D21, D22, D23, capacitor C 21, C22, C23, C24, C25, C26, C27, C28, resistance R 21, R22, R23, R24, R25, R26, R27, R28 etc., HL is an illuminating lamp.Contact d, e are used for respectively being connected with light-controlled switching circuit that can produce the light-operated switch signal and civil power.When civil power after inserting the lamp holder circuit under the control of aforementioned lights controlled switch circuit, through capacitor C 28 step-downs, after diode D23 voltage stabilizing, the diode D22 rectification, provide 9V DC power supply.Clapping is picked up by driving polar body microphone M, delivers to the input of integrated circuit (IC) 2 after triode V21 amplifies, and triggers the time-base circuit upset, and output is a high level, the controllable silicon SCR conducting, and illuminating lamp HL lights.Resistance R 26 and capacitor C 26 have determined the retention time of output level, if resistance R 26 is 22 μ f for 1M Ω, capacitor C 26, then lamp is bright about 20 seconds, and as capacitor C 26 being changed into 100 μ f, then lamp is bright about 100 seconds.The reverse leakage resistance of diode D21 constitutes delay circuit with capacitor C 24, and switch rigidly connects when leading to, and capacitor C 4 is slowly charged, and 4 pin current potentials of integrated circuit (IC) 2 do not allow lamp bright once opening from zero toward rising at leisure, and after two minutes, if any clapping, lamp is just normally bright.The foregoing description is when practical application, easily experience the bright place of natural daylight near light-controlled switching circuit partly can being located at total kilowatt-hour meter, and being located at every floor stair mouth or lavatory, passageway, porch etc., one or several lamp holder circuit locates, thereby make resident family etc. can be at night through or can obtain suitable illumination when using above-mentioned position, can make again simultaneously lamp when appropriate between the back from horizontal blanking.Reach and concentrate purpose light-operated, that disperse acoustic control.Present embodiment is highly sensitive, can not move in advance at rainy day, dusk, strong interference immunity, daytime switch by unexpected shading, can not open in 3 minutes, bright suddenly near the evening switch, can not cut off the power supply in 3 minutes.

Fig. 2 has described another embodiment of the present utility model.Comprise time-base integrated circuit IC3(model NE555 in the circuit), controllable silicon SCR 2, drive polar body microphone M2, photosensitive tube V33, triode V34, V32, diode D31, D32, D33, capacitor C 31, C32, C33, C34, C35, C36, C37, resistance R 31, R32, R33, R34, R35, R36, R37, R38, R39, R30 etc.HL is an illuminating lamp.Civil power after diode D31 voltage stabilizing, the diode D32 rectification, provides 9V DC power supply through capacitor C 37 step-downs.Clapping is picked up by driving polar body microphone M2, delivers to the input of integrated circuit (IC) 3 after triode V31 amplifies, and triggers the time-base circuit upset, and output is a high level, controllable silicon SCR 2 conductings, and illuminating lamp HL lights.Resistance R 36, capacitor C 35 have determined the retention time of output level.4 pin of IC3 are the general reset end, and this terminal voltage is if be lower than 1V, and time-base circuit just can not overturn.On daytime, photosensitive tube V33 conducting, triode V32 satisfy and close, and 4 pin current potentials of integrated circuit (IC) 3 are lower than 1V, time-base circuit is lockable, and when light is very dark (evening), it is very big that the resistance of photosensitive tube V33 becomes, the collector potential of triode V32 is improved, and it is normal that time-base circuit recovers.So, can realize the pattern that works independently of lamp holder circuit, and need not the extra light-operated switch in the last example.Diode D33 and resistance R 39 in the circuit have constituted the positive feedback latching circuit.Add that this circuit is because if light-operated sensitivity is very high, so, after the lamp of clapping hands evening was bright, the secondary reflection of self light shone again on the photosensitive tube, impel integrated circuit 4 pin current potentials to descend rapidly again, thereby controllable silicon can turn-off once more.And if light-operated sensitivity is lower, though the secondary reflection effect of self light can be ignored, at overcast and rainy or dusk, lamp will be bright when it was also not very black.Added the positive feedback latching circuit, just can work as after photosensitive tube is subjected to make less than illumination the amplifying triode collector potential to rise, if integrated circuit 2 pin obtain triggering signal, output pin 3 pin just skip to high potential, the controllable silicon conducting, lamp is bright, simultaneously, diode D33 feeds back to general reset end (4 pin) with high potential, makes 4 pin keep high potential, like this, even photosensitive tube is illuminated by self bulb, the collector potential of amplifying triode V32 descends, but because the effect of isolation resistance R39, integrated circuit 4 pin current potentials still keep high potential, and lamp just extinguishes bright extremely specified delay value.Bidirectional triode thyristor adopts the very little import plastic packaging type of trigger current, and the resistance of resistance R 37 can be increased to 2K Ω (or other appropriate values), and it is very little that power consumption of integrated circuit becomes, and avoided the heating phenomenon of integrated circuit behind frequent operation.For the thermal stability that improves sound control circuit, make its four seasons unanimity, seal in variable resistor R38 at the emitter of amplifying triode V31, introduce a bigger amount of negative feedback, like this, when microphone sensitivity is inconsistent,, be convenient to produce in enormous quantities as long as adjust variable resistor R38.

Consider that product needs demonstration and repair in the shop, at capacitor C 37 two ends and a resistance is arranged, discharge path is provided for capacitor C 37, save the trouble of manual discharge.
