Brief description
Fig. 1 is the circuit diagram of portable led lantern.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1, a kind of portable led lantern, including electric capacity c1, chip ic1, diode d1 and button k1, institute
The one end stating electric capacity c1 connects the positive pole of inductance l1 and power supply e, the other end of electric capacity c1 connect electric capacity c2, electric capacity c3, electric capacity c4,
Electric capacity c5, resistance r4, resistance r5, resistance r6, a fixing end of potentiometer rp1, the pin 7 of chip ic1, light fixture h and power supply e
Negative pole, the other end of electric capacity c2 connects resistance r3, the pin 2 of resistance r4 and chip ic1, and the other end of resistance r3 connects resistance
The other end of r2, resistance r2 connects resistance r1, resistance r7, the pin 6 of resistance r8, the negative electrode of diode d1 and chip ic1, resistance
The other end of r1 connects the pin 1 of chip ic1 and the pin 4 of chip ic1, and the other end of electric capacity c3 connects the other end of resistance r5
With the pin 3 of chip ic1, the other end connection anode of diode d1 of inductance l1 and the pin 8 of chip ic1, chip ic1 draws
Foot 5 connects electric capacity c4, button k1, the sliding end of button k2, another fixing end of potentiometer rp1 and potentiometer rp1, resistance r8
The other end connect the other end of button k1, the other end of button k2 connects the other end of resistance r6, and the other end of resistance r7 is even
Connect the other end of light fixture h, model mc34063 of described chip ic1.
As preferred version of the present utility model: described power supply e is 1.5v aneroid battery.
As preferred version of the present utility model: described light fixture h is LED lamp.
Operation principle of the present utility model is: ic1 is dc dc transducer, and it is with energy storage inductor l1, diode d1, electric capacity
C5 etc. forms self-oscillatory booster switcher power supply, and the 1.5v voltage of power supply e is risen to 3.9v, provides work electricity for light fixture h
Source.Resistance r7 is current-limiting resistance.
Monostable trigger within ic1 and output stage mos field effect transistor limit the arteries and veins of peak point current with external circuit composition
Wide modulating system, its switching frequency is determined with the ratio of output voltage and the inductance value of output and l1 by input voltage, its
Frequency is about 180khz.Output voltage is determined by the ratio of feedback resistance r2, r3 and r4, and wherein r3 is used for adjusting output voltage
Just.Electric capacity c2 is alternating current bypass electric capacity.
5 feet of ic1 are used to detect battery low-voltage.When the 1.24v reference voltage within cell voltage is down to ic,
Open-drain, outfan 4 foot of ic1 will turn off, and 1 foot is pulled to low level, makes ic1 stop output.And at this moment in circuit,
Because cell voltage only has 1.5v, therefore be changed to timing to automatically switch off, that is, when pressing s1, c4 through r8 be charged to rapidly close to
The output voltage of ic1, makes the comparator within ic1 overturn, then 1 foot of ic1 is pulled to high level by r1, and then ic1 starts working,
Light fixture h is lighted.When unclamping s1, electric capacity c4 just starts to discharge through potentiometer rp1, after a period of time, under the both end voltage of c4
Fall below the reference voltage within ic1, comparator output uprises, the 1 foot current potential step-down of chip ic1, then ic1 stops output,
Light fixture h extinguishes, and the value changing potentiometer rp1 easily can adjust the fall time, even if button k2 is used for turning off light fixture h, presses
Lower k2, electric capacity c4 discharge rapidly through r6, and light fixture h extinguishes immediately.
