Description
Technical field
The utility model relates to a kind of circuit control module, particularly a kind of acoustooptic controlled delay circuit module.
Background technology
Current LED lamp is popularized gradually, and traditional single live wire sound and light controlled delay switch, can only the above energy-saving lamp load of control 7W because standby current is comparatively large; Below 7W electricity-saving lamp and LED lamp, because starting current is less, when using traditional single live wire sound and light controlled delay switch, in the off case, often produce flicker, thus easily cause light fixture to damage.This circuit standby current can be controlled in below 20uA, completely solves the drawback of traditional single live wire sound and light controlled delay switch, adapts to LED lamp and the energy-saving lamp of any more than 3W, and simple circuit, consistency is high, is easy to volume production.
Utility model content
In order to solve deficiency of the prior art, the utility model proposes a kind of acoustooptic controlled delay circuit module.The technical scheme adopted is as follows:
A kind of acoustooptic controlled delay circuit module, comprises rectification unit, performance element, control unit and sensing acquisition unit, it is characterized in that: rectification unit is made up of rectifier diode D1-D4; Performance element is made up of controllable silicon Q and diode D5, diode D6; Control unit forms primarily of module U2; Sensing acquisition unit is made up of photo resistance CDS and sound transducer MK; Rectification unit connects LED, LED connection control unit composition loop; The pin 3 of control unit connects photo resistance CDS, and pin 4 connects sound transducer MK.
The beneficial effects of the utility model are as follows:
Relative to the utility model like product have substituting strong, starting current is little, adapts to LED lamp and the energy-saving lamp of any more than 3W, and simple circuit, consistency is high, is easy to volume production.
Accompanying drawing explanation
Fig. 1 is circuit diagram of the present utility model;
Reference numeral:
1 one rectification units, 2 one performance elements, 3 one control units, 4 one sensing acquisition unit
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with accompanying drawing, the utility model is further elaborated.
Shown in Figure 1, a kind of acoustooptic controlled delay circuit module, comprises rectification unit 1, performance element 2, control unit 3 and sensing acquisition unit 4, it is characterized in that: rectification unit 1 is made up of rectifier diode D1-D4; Performance element 2 is made up of controllable silicon Q and diode D5, diode D6; Control unit 3 forms primarily of module U2; Sensing acquisition unit 4 is made up of photo resistance CDS and sound transducer MK; Rectification unit 1 connects LED, and LED connection control unit 3 forms loop; The pin 3 of control unit 3 connects photo resistance CDS, and pin 4 connects sound transducer MK.
Operation principle:
This circuit is made up of rectification unit, performance element, control unit and transducer collecting unit.This circuit connected in series accesses 220V civil power in lamp load loop, and what circuit itself adopted is that single live wire is powered, substituting extremely strong.
Embodiment one
Loop is produced by LED light, control unit U2 after the rectification unit rectification that power supply consists of D1-D4, control unit U2 adopts micro-current conduction mode, make whole circuit standby current at below 20uA, the real-time testing environment illumination of photo resistance CDS of sensing acquisition unit, when ambient light illumination is greater than 400lm, CDS is in bright resistance state, and control unit is in dormancy holding state; When ambient light illumination is less than 400lm, CDS is in resistance in the dark state, control unit U2 starts the signal receiving sound transducer MK, when ambient sound reaches 80db, control unit U2 module 2 pin outputs a control signal to performance element and triggers controllable silicon Q conducting, and performance element Q, D5, D6 form big current loop and light lamp load; Delay time is by control unit inner setting, and after delay time, whole circuit returns to holding state, waits for triggering work next time.
Under solving conducting state, control unit powerup issue, ingeniously in performance element controllable silicon loop seals in D5, D6, improves the voltage of performance element end under conducting state and reaches 2V, thus ensure that the normal Standby voltage of control unit.
This circuit LED light is serially connected in U2 electric power loop, utilize that 20uA standby current is micro-to be lighted, connect need consume extracurrent unlike other circuit in parallel, sound transducer selects piezoelectric ceramic piece, to ensure when standby not current sinking substantially, add the micro-current lead-through design of U2, whole circuit standby current is controlled at below 20uA, thus ensure that this circuit can reliably working for the most of light fixture comprising 3W LED lamp.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
