Abstract

The utility model relates to an acoustic optic control time-delay energy-saving lamp cap, which comprises a terminal box, an upper connector, a lower connecting base and a power control circuit. The utility model has the advantages of simple structure, low cost and convenient operation; the acoustic optic control time-delay energy-saving lamp cap can be directly connected with the existing lamp cap and the lamp bulb without changing the original lines; lamps can be lightened only in the condition of sounds and vibration; the utility model is an ideal product for public places, corridors, stairways and toilets.

Description

Acoustooptic control time-delay energy-saving lamp base

The utility model relates to the energy-conservation lamp holder of a kind of time-delay, particularly a kind of energy-conservation lamp holder of time-delay with acousto-optic control.

The used lamp holder of existing illumination, generally adopt power supply directly to be communicated with bulb, and need switch to be controlled, such illuminating lamp holder does not possess electricity-saving function, and open and close are cumbersome, especially for corridor, stair illumination etc., the pass swap switch because people can not feel about in the dark, cause bright whole night lamp, both wasted electric energy, reduce the useful life of bulb again.At present, occurred a kind of touch delay switch on the market, the phenomenon of waste electric energy is improved, but it has been very inconvenient to remove to touch this switch in the pitch-dark late into the night.Recently, some producers develop the delay switch of acousto-optic control, but this switch must be looked for the former circuit of electrician's reconfiguration when mounted, promote the use of and will be subjected to certain restriction.

It is a kind of simple in structure that the purpose of this utility model is to provide, and cost is low, uses easy to maintenancely, do not change original circuit, and can be connected with bulb with existing lamp holder, as long as the energy-conservation lamp holder of acousto-optic control time-delay that vibrations can bright lamp is arranged.

The utility model is to realize like this, it is made up of terminal box, top connection, following joint chair and power control circuit, the top of terminal box is provided with top connection, the bottom is equipped with down joint chair, and power control circuit is housed in it, the piezoelectric patches that power control circuit is provided with, power supply indication and photo resistance, draw by lead-in wire respectively, and be installed on the terminal box, like this, can constitute the energy-conservation lamp holder of a kind of acousto-optic control time-delay.

Be illustrated below in conjunction with accompanying drawing.

Fig. 1 is an overall structure generalized section of the present utility model.

Fig. 2 is power control circuit figure of the present utility model.

Fig. 3 is the circuit block diagram of Fig. 2.

As shown in Figure 1, 2, 3, control the energy-conservation lamp holder of time-delay by the acousto-optic that terminal box ［ 1 ］, top connection ［ 2 ］, following joint chair ［ 3 ］ and power control circuit ［ 4 ］ are formed, the top of its terminal box ［ 1 ］ is provided with top connection ［ 2 ］, the bottom is provided with joint chair ［ 3 ］ is installed down, top connection ［ 2 ］ is drawn ［ 5 ］ one of two-lines and is connected in the circuit, article one, directly be connected with following joint chair ［ 3 ］ one ends, the other end wiring of following joint chair ［ 3 ］ links to each other with circuit.Power control circuit ［ 4 ］ is housed in the terminal box ［ 1 ］, power control circuit ［ 4 ］ is to be made of power circuit A, sound detection circuit B, light testing circuit C and delay control circuit D, and power circuit A is made of rectifier diode D1-D4, dropping resistor R11, filter capacitor C4, voltage stabilizing didoe D6; Sound detection circuit B is made of piezoelectric patches HTD, triode V1-V3, resistance R 1-R6, capacitor C 1-C3; Light testing circuit C is made of photo resistance RG, triode V4, diode D5, electrochemical capacitor C5 and resistance R 7; Delay control circuit D is made of unidirectional controllable silicon S CR, triode V5, V6, resistance R 10, R12.The 220V alternating voltage through R11 decompression capacitor C4 filtering, again through the D6 voltage stabilizing, remains on about 9V the D6 both end voltage, for other circuit working after the D1-D4 rectification.When chatter is sounded signal, at the voltage that two ends produced of piezoelectric patches HTD after the amplifier that V1-V3 forms amplifies, signal through R8 and the output of V4 collector electrode makes the operating state of V5 change jointly, daytime is when having irradiate light, RG resistance is very little, and the V4 conducting makes the base stage of V5 be in electronegative potential, because the conducting of V4 is also with detected voice signal short circuit by day, so daytime, acoustic control was inoperative.During to evening, because the resistance of RG increases, V4 ends, and at this moment the voice signal of being sent here by R8 is directly controlled the conducting of V5 and ended, when voice signal, the V5 conducting, V6 ends, and the V6 collector voltage raises and triggers the SCR conducting, 220V voltage is through D1-D4, SCR, illuminating lamp DZ form the loop, and bulb is lighted, after voice signal disappears, V5 ends, C6 charges by R10, after one minute about, V6 is conducting again, SCR ends, illuminating lamp extinguishes, and when the voice signal of vibration is arranged again, just occurs said process again.

LED is both as the power supply indication in the circuit, and as the operating state indication, light-emitting diode did not work when promptly lamp was bright again, and light-emitting diode was not bright when lamp worked; Photo resistance RG among the light testing circuit C is in parallel with electrochemical capacitor C5, to improve the antijamming capability of light-operated switch; Increasing D5 can increase the reliability of system; Change the light-operated sensitivity of R7 scalable; The value that changes R10 or C6 can change delay time simultaneously.

Piezoelectric patches HTD ［ 6 ］ in the circuit, photo resistance RG ［ 7 ］ and LED ［ 8 ］ are also drawn by lead-in wire ［ 5 ］ respectively, and directly are contained in terminal box on ［ 1 ］.
