Description

Sound-light controlled LED lamp

Technical field

The utility model relates to the lighting device of a kind of LED of use as light source, especially is subjected to light-operated long-time the low light level to be subjected to acoustic control to send out the lamp of sending out the low light level after high light automatic time delay a period of time again again.

Background technology

In prior art, Chinese patent ZL200720072710.0 provides a kind of, is subjected to light-operated long-time the low light level to be subjected to acoustic control to send out the acousto-optic control light-emitting diodes tube loop sense light of sending out the low light level after high light automatic time delay a period of time again again; Described as can be known by its circuit theory diagrams and specification: light-operated circuit does not have interference protection measure, scintillation can occur when light is in its critical condition or the interference of other light; Its control circuit power supply and light source power is shared and be the resistance-capacitance depressurization bridge rectifier, only by a resistance step-down, be acousto-optic control circuit electric current to be added to LED send out the low light level during its low light level, by resistance-capacitance depressurization bridge rectifier principle as can be known, the low light level and high light are led bigger by the also different output voltage difference of different its pressure drop of resistance-capacitance depressurization circuital current, the control circuit job stability can be influenced, and low light intensity is non-adjustable; And controllable silicon T4 conducting when not luminous on daytime, with acousto-optic control circuit electric current through T4, R15 to bridge rectifier, make LED terminal voltage low not luminous (LED sends out the low light level and needs a milliampere level electric current), so quiescent dissipation is bigger; Because of it uses element more, volume is big, cost is higher, and performance is not ideal enough.

The utility model content

The utility model is at above deficiency, provide a kind of working stability, anti-interference, quiescent dissipation is little, simple in structure, volume is little, cost is lower, the long-time low light level of lamp is bright when unglazed, has the brighter or continuous sound of sound can brighter continuously sound-light controlled LED lamp.

For solving the problems of the technologies described above, solution of the present utility model is as follows:

Control circuit power supply and light source power use independent power supply, and the control circuit power supply uses little power consumption voltage-stabilized power supply, working stability like this, and quiescent dissipation is little; Light-operated circuit is controlled little current control circuit behind anti-jamming circuit, the long-time low light level is bright and can make things convenient for as required and adjust low light intensity when making lamp unglazed; The acoustic control delay circuit is controlled big current control circuit, and is subjected to light-operated circuit control to make lamp have the brighter or continuous sound of sound can be brighter continuously; Because of using element still less, so structure is simpler, volume is littler, cost is lower.

Characteristics of the present utility model are: simple in structure, quiescent dissipation is low, power savings is remarkable, long service life, volume is little, cost is low, the long-time low light level of lamp is bright when unglazed, there is the brighter or continuous sound of sound can be brighter continuously, reduces in dark surrounds suddenly high light the incompatibility sense of eye; The use in places such as suitable especially corridor, corridor, toilet and garage.

The specific embodiment

Consult Fig. 2, the utility model be described in further detail:

When energising, 220 volts of civil powers are through the D1 rectification, the step-down of R2 current limliting, and C3 filtering, Q1 (small-power silicon triode) voltage stabilizing is for control circuit provides power supply; Daytime is because the little U1-D 12 of RG (photo resistance) resistance, 13 pin are high level, 11 pin are low level (T1 by) and to make U1-B 6 pin by R9 be low level 4 pin high level, this moment U1-C 8,9 pin are high level, 10 pin end for low level T2, no matter at this moment there is the voiceless sound led light source circuit entire circuit of not working to be in static state, because control circuit power supply (little power consumption voltage-stabilized power supply) separates with light source power, (small-power silicon triode emitter junction is in the reverse breakdown state to use Q1 again, only need consume electric current below tens microamperes and just can have good pressure stabilization function) voltage stabilizing, its load MIC (Electret condenser microphone), U1 is the COMS circuit, T1, T2 is that common 1A600V controllable silicon only needs tens microamperes of electric currents just can reliably trigger, so the utility model working stability, quiescent dissipation very low (microampere order), power savings is remarkable.

When at dark, RG (photo resistance) resistance increases U1-

D

12,13 pin are low level, 11 pin be high level (making U1-B 6 pin by resistance R 9 simultaneously is high level) at this moment R10 be that C7 charging time-delay is anti-interference, trigger controllable silicon T1 conducting by current-limiting resistance R12 after charging a period of time, at this moment 220 volts of civil powers are through R1, C1, D2, D3, D4, behind the D5 step-down rectifier, adding to LED1-LEDN by current-limiting resistance R3, to form loop LED through the R14 current limliting to T1 more luminous, C2 filtering and prevent that LED is hit, because current-limiting resistance R14 resistance is bigger, so by less long-time the low light level of LED electric current; Can adjust the convenient low light intensity of adjusting of R14 size as required, because of there being delay anti-jamming circuit the lamp scintillation can not occur, at this moment obtain operating voltage if any sound MIC (Electret condenser microphone) by R4, it is feedback resistance that the voice signal that picks up is coupled to U1-A amplification R5 through C4, signal after the amplification adds to U1-B 5 pin through C5, at this moment U1-B5, it is low level that 6 pin are all high level 4 pin, diode D6 conducting C6 is by D6 charging U1-C 8,9 pin are that low level 10 pin are that high level triggers controllable silicon T2 conducting through current-limiting resistance R13, at this moment T2 short circuit current limitation resistance R 14 makes by LED electric current increase lamp brighter, if there is the sound can be brighter continuously continuously, sound is D6 U1-C 8 after C6 is by R8 discharge time-delay a period of time later, it is low level that 9 pin are all high level 10 pin, T2 sends out the low light level by LED, makes LED avoid heavy current impact; So the utility model long service life, can reduce in dark surrounds suddenly high light to the incompatibility sense of eye, because of the use element is few, so simple in structure, volume is little, cost is low, the use in the places such as corridor, corridor, toilet and garage that suit especially.
