Below in conjunction with the drawings and specific embodiments optimum embodiment of the present utility model is described in detail.
As shown in Figure 1, be the functional-block diagram of the preferred implementation of intelligent control LED illumination circuit of the present utility model; This intelligent control LED illumination circuit comprises high voltage source converter unit 1, led circuit unit 3, intelligent switch unit 21, ac input power intelligent control unit 22, ac input power converter unit 23, the input of described intelligent switch unit 21 is electrically connected with the output of described high voltage source converter unit 1, the output of described intelligent switch unit 21 is electrically connected with the input of described ac input power intelligent control unit 22 and described led circuit unit 3, the output of described ac input power intelligent control unit 22 is electrically connected with the input of ac input power converter unit 23, and the output of described ac input power converter unit 23 is electrically connected with high voltage source converter unit 1.Be provided with feedback control unit 24 between described intelligent switch unit 21 and the described ac input power intelligent control unit 22; Described intelligent switch unit 21 is electrically connected with the input of described ac input power intelligent control unit 22 and described led circuit unit 3 by low-tension supply power taking unit 25; Between described intelligent switch unit 21 and the described led circuit unit 3 filtering smooth unit 31 is set.Wherein intelligent switch unit 21 makes up formed switch element for any one or more control circuit in the induction detection control circuits such as light, sound, human body, infrared, microwave, radio, flue dust, temperature-sensitive or air-sensitive induction, and what this preferred embodiment adopted is the light-operated switch unit.Described interchange input intelligent control unit 22 be that any one or more control circuit makes up in sound, light, human body, infrared, microwave, radio, flue dust, temperature-sensitive or the air-sensitive inductive control circuit.When ambient brightness was strong, intelligent switch unit 21 was closed, and made ac input power conversion intelligent control unit not work owing to there is supply voltage, and whole loop current is very faint, and LED can't light, and this moment, the power consumption of entire circuit was almost nil.When ambient brightness is more weak, 21 conductings of intelligent switch unit, power to the ac input power converter unit by low-tension supply unit 25, ac input power intelligent control unit 22 is started working and is in holding state, as sound, human body, infrared, microwave, radio, flue dust, when heat or gas signal, ac input power intelligent control unit 22 control ac input power converter units 23, make ac input power become big, it is bright entirely that whole loop current increases LED, feedback control unit 24 sends feedback signal to light-operated intelligent switch element 21 simultaneously, with the high light that prevents LED self the light-operated intelligent switch is turn-offed.
Be illustrated in figure 2 as the circuit diagram of the preferred embodiment of intelligent control LED circuit of the present utility model, this example is the multi-level brightness sound-light controlled LED lighting lamp circuit of a 2-3W, intelligent control module is parallel to the voltage-stabiliser tube that is serially connected between low-power high-voltage DC power supply, intelligent switch element and the LED unit, utilize pressure drop on the voltage-stabiliser tube to form low-tension supply and give the power supply of Based Intelligent Control time delay module, thus again by the control of Based Intelligent Control time delay module exchange input current realize high efficiency multi-level brightness control and daytime almost nil stand-by power consumption.Input insurance F1, surge absorb piezo-resistance VR1, resistance-capacitance depressurization (C2, R1), bridge heap D2 composition low input power power conversion module 1 in Fig. 2, provide voltage to entire circuit; Q7, Q5, R16, R17, R18, PR1, D7, R11 form intelligent control switch circuit 2, wherein, the compound composition contactor of Q5, Q7, Q5, R16, R17, R18, PR1, D7, R11 form the light-operated intelligent switch element, D6, C10, U3, C8, C9 form low-voltage power circuit 3: acoustic control intelligent AC input power translation circuit 4:C1, TR1, D2, D1, Q1, R2, U1, D3, R3, C3, composition input power translation circuit, and R13, D5, R12, R10, Q4 constitute feedback unit; Remaining element is formed acoustic control intelligence delay circuit, and C12, R15 are the output filter unit.The PR1 resistance was little when daytime or ambient brightness were strong, and Q6, Q5, Q7 end, and acoustic control intelligent AC input power translation circuit is not worked because of non-transformer voltage, and whole loop current is very faint, and LED can't light, and this moment, the power consumption of entire circuit was almost nil.The resistance of PR1 became big when evening or ambient brightness were more weak, the Q6 conducting, and Q5, Q7 be and then conducting also.This moment, input power was limited owing to be subjected to the less impedance of C1 capacity big, and whole loop current is little, is about 2-3W in this example, and LED is in dark bright state.Design the quantity of the parameter of suitable C1 and LED and string and structure and can obtain different-effect.Simultaneously acoustic control intelligent AC input power translation circuit has supply voltage and starts working and be in holding state.When environment has sound to occur, this voice signal converts the signal of telecommunication to and triggers NE555 monostable flipflop state turnover through Q2, Q3 two-stage after amplifying through the MIC1 transducing, NE555 tripod output high level, the optocoupler conducting, the gate pole of Q1 gets electric triggering and conducting, and this moment, bridge heap D2 was equivalent to short circuit, and C1 and C2 are equivalent to parallel operation, it is big that ac input power becomes, and it is bright entirely that whole loop current increases LED.This high level signal feeds back to the light-operated intelligent switch element through R13, D5, Q4 simultaneously, with the high light that prevents LED self the light-operated intelligent switch is turn-offed.Design the quantity string of the parameter of suitable C1 and C2 and LED and structure with the current work that guarantees LED within 20mA.Stable state before NE555 monostable flipflop state delay was returned to after a period of time, the length of delay time is determined by the size matching of R14, C11.Therefore, the LED intelligent switch device that this example provided can be realized almost nil stand-by power consumption and multi-level brightness illumination control, has overcome traditional intelligent control switch and have the stand-by power consumption of 0.5-1W to waste all the time, can't carry out multi-level brightness control and dark defective and deficiencies such as efficient is low when bright.
Need to prove the above disclosed a kind of preferred embodiment of the utility model that only is, certainly can not limit the interest field of the utility model with this, all equal variation and modifications of being done according to the utility model claim scope all should belong to the covering scope of the utility model claim.Small change on any conspicuous replacement or the circuit (as transistor is replaced with controllable silicon, controllable silicon replaces with the element of switching characteristics such as transistor, metal-oxide-semiconductor) all belongs within the protection range of the present invention.
