Description
Technical field
The invention belongs to Electric automatic control and lighting technical field, relate to a kind of photosensitive control LED illumination lamp.
Background technology
The impact resistance of incandescent lamp and electricity-saving lamp is very poor, although electricity-saving lamp economize on electricity, settles and costly becomes common recognition, and a lot of corridor lamp ceaselessly switch all day long, causes it constantly to damage, constantly change, and constantly increases human and material resources and expenditure.LED economize on electricity 80% compared with ordinary incandescent lamp of same power, LED has superpower economize on electricity, extra long life, and LED also has a maximum advantage to be can frequent switch, and the frequent Switch Controller life-span does not affect substantially.Photosensitive control LED illumination lamp does not work daytime, only has when ambient light is dimmed or just can automatically light after darkness.Therefore, it can be used as the illumination of aisle, public place, or the place needing night low-light to throw light on, and the family being also particularly suitable for old man or child uses.
The circuit of photosensitive control LED illumination lamp of the present invention possesses light-operated and energy-conservation two kinds of effects, and it can open LED at dark automatically, LED automatically can be closed again after daybreak.Photosensitive control light-emitting diode (LED) illuminating lamp has that circuit is simple, working stability, dependable performance, and circuit only uses a small amount of common discrete component, and cost of manufacture only needs a few unit, is suitable for factory's batch exploitation.
Below describe in detail photosensitive control LED illumination lamp of the present invention necessity involved in implementation process, guardian technique content.
Summary of the invention
Goal of the invention and beneficial effect: the circuit of photosensitive control LED illumination lamp of the present invention possesses light-operated and energy-conservation two kinds of effects, and it can open LED at dark automatically, LED automatically can be closed again after daybreak.The family that it is also particularly suitable for old man or child uses.Therefore, it can be used as the illumination of aisle, public place, or the place needing night low-light to throw light on, and the family being also particularly suitable for old man or child uses.Photosensitive control light-emitting diode (LED) illuminating lamp has that circuit is simple, working stability, dependable performance.
Circuit working principle: in photosensitive control LED illumination lamp circuit, photo resistance RG is accessed between the base stage of NPN type triode VT1 and circuit ground GND, form optical signal detecting circuit, to provide half-light automatic control signal, its luminous sensitivity is regulated by potentiometer RP, makes reliable conducting or the cut-off of NPN type triode VT1; Thus control the VT1 conducting of enhancement mode N channel field-effect pipe or cut-off, and then white light-emitting diode LED1 ~ LED12 is made to light or extinguish.
Time by day, brighter owing to being subject to natural light irradiation ambient light, photo resistance RG light is irradiated, its resistance is less, the base voltage of NPN type triode VT1 is made to be locked in electronegative potential, so NPN type triode VT1 quits work, now enhancement mode N channel field-effect pipe VT1 also ends, because white light-emitting diode LED1 ~ LED12 does not work without working power.
When ambient light is comparatively dark or after darkness, because the unglazed irradiation of photo resistance RG makes its resistance increase, lose the control ability to NPN type triode VT1 base stage, so, export between high period at the emitter of NPN type triode VT1, drive white light-emitting diode LED1 ~ LED12 luminous by enhancement mode N channel field-effect pipe VT1.During the emitter output low level of NPN type triode VT1, because enhancement mode N channel field-effect pipe VT1 ends, white light-emitting diode LED1 ~ LED12 is extinguished.
Technical characteristic: photosensitive control LED illumination lamp, it comprises 12V DC power supply, optical signal detecting and amplifying circuit, LED power drive circuit, it is characterized in that:
Optical signal detecting and amplifying circuit: it is made up of photo resistance RG, linear potentiometer RP, resistance R1, NPN type triode VT1 and resistance R2, the base stage of NPN type triode VT1 connects one end of linear potentiometer RP and one end of photo resistance RG by resistance R1, the other end of linear potentiometer RP and movable end connection circuit positive pole VCC thereof, the other end connection circuit ground GND of photo resistance RG, the emitter of the collector electrode connection circuit positive pole VCC of NPN type triode VT1, NPN type triode VT1 is by resistance R2 connection circuit ground GND;
LED power drive circuit: it is by resistance R3, enhancement mode N channel field-effect pipe VT1 and white light-emitting diode LED1 ~ LED12 forms, the grid of enhancement mode N channel field-effect pipe VT1 connects the emitter of NPN type triode VT1 by resistance R3, the drain electrode of enhancement mode N channel field-effect pipe VT1 connects the negative pole of the negative pole of white light-emitting diode LED4 and the negative pole of white light-emitting diode LED8 and white light-emitting diode LED12, white light-emitting diode LED1 ~ LED4 contacts mutually, white light-emitting diode LED5 ~ LED8 contacts mutually, white light-emitting diode LED9 ~ LED12 contacts mutually, the positive pole connection circuit positive pole VCC of the positive pole of white light-emitting diode LED1 and the positive pole of white light-emitting diode LED5 and white light-emitting diode LED9, the source electrode connection circuit ground GND of enhancement mode N channel field-effect pipe VT1,
The positive pole of 12V DC power supply is connected with circuit anode VCC, and the negative pole of 12V DC power supply is connected with circuit ground GND.
Accompanying drawing explanation
