A battery in the LED lamp is durable. The LED lamp uses super bright lamp beads dedicated to a torch, wherein the power of each lamp bead is between 3 and 5W. The battery is a lithium battery with a model number of 16340. Charging current is pulsating current about 80mA.
Description
Technical field
The illumination that the present invention relates to the anti-overdischarge of the anti-overcharge energy of a kind of energy is met an urgent need dual-purpose LED.
Background technology
The market of current LED is raised variety various, and just the function singleness of LED, does not substantially have throw light on and the dual-purpose LED of tool emergency light function, illuminating lamp being had a power failure suddenly once encounter civil power, emergency light be looked for use, very inconvenience; Be again that some place is seen to have and can be thrown light on and the dual-purpose LEDbulb lamp of power failure time delay, but not there is anti-overcharge and anti-overdischarge function, the battery of power failure time delay is easily damaged.
Summary of the invention
The illumination of the anti-overdischarge of the anti-overcharge energy of energy is met an urgent need a dual-purpose LED, discloses a kind of LED illumination lamp, is furnished with lithium battery and charging circuit in the lamp body of this lamp, and have anti-overcharge Electricity Functional when having charging; There is during electric discharge anti-overdischarge function, ensure the durability of lithium battery.
The illumination of the anti-overdischarge of the anti-overcharge energy of energy is met an urgent need a dual-purpose LED, and its circuit composition is inputted three-terminal voltage-stabilizing circuit, anti-overcharge circuit, anti-overdischarge road, light-operated circuit and LED luminous plaque formed by resistance-capacitance circuit, current rectifying and wave filtering circuit, high voltage.
Accompanying drawing explanation
Accompanying drawing 1 is that the illumination of the anti-overdischarge of the anti-overcharge energy of a kind of energy is met an urgent need the circuit theory diagrams of dual-purpose LED.
Embodiment
As shown in drawings, R6, C4 form capacitance-resistance voltage reduction circuit, alternating current 220V is reduced some volts and sends to rectification circuit.Described current rectifying and wave filtering circuit is made up of D1, D2, D5, D6, L, C5, and wherein D1, D2, D5, D6 form single phase bridge type rectifier circu, and the direct current alternating current after step-down being become pulsation send filter circuit.Described filter circuit is made up of inductance L and electric capacity C5, and the direct current of pulsation is become smoother direct current supply next stage circuit.
As shown in drawings, the voltage that T, D7, R7, C6, C7, C8, IC1 form the input of high voltage input three-terminal voltage-stabilizing circuit is about 45V, and the voltage of output is 5V, and namely the model of IC1 is 7805.
As shown in drawings, anti-overcharge circuit is made up of D4, and D4 is both-end voltage-stabiliser tube, selects voltage to be the both-end pressurizer of 3.7V, when battery is not full of electricity, the voltage at battery two ends is lower than 3.7V, then D4 does not have breakdown, and battery continues punching electricity, when battery is charged to 3.7V, D4 two ends press and reach puncture voltage, now D4 is breakdown, i.e. conducting, plays and prevents battery overcharge.
As shown in drawings, anti-overdischarge circuit is made up of IC4 and D11, the switch chip of IC4 to be model be HTW8778, the both-end pressurizer of D11 to be voltage be 2.4V, when anti-electric voltage is reduced to below 2.4V, D11 ends, and makes the 5 pin voltages of IC4 be in electronegative potential, and IC4 ends, non-transformer is passed to LED, LED extinguishes, and plays and prevents overdischarge effect, prevent overdischarge from making cell damage.
As shown in drawings, IC2, IC3 and peripheral circuit composition light-operated circuit, IC2 is power switch IC, and model is TWH8778, when its 5 pin voltage is higher than more than 1.6V, IC2 conducting, the voltage of 1 pin outputs to 2,3 pin; When the voltage of 5 pin is lower than 1.6V, IC2 ends, IC2 no-output.The model of IC3 is time-base circuit 555, R2 is photo resistance, and by day, irradiate by light, its resistance is low value, causes 2 of IC3,6 pin current potentials to raise.When 2, the 6 pin current potentials of IC3 are elevated to 2/3U
cCtime above, its 3 pin output low level, make the 5 pin voltages of IC2 lower than 1.6V, IC2 cut-off, when ensureing daytime, even if civil power stops confession, LED does not work yet; At night, it be high value that dull thread irradiates R2, R2, causes 2 of IC3,6 pin current potentials reductions, when lower than 1/3U
cCtime, its output 3 pin exports high level, and the 5 pin voltages of effect IC2 are higher than 1.6V, and make IC2 conducting, the voltage of 1 pin outputs to 2,3 pin.When the voltage that IC2 exports is higher than 2.4V, IC4 conducting, LED obtains electricity and lights, and plays emergency light function; When the output voltage of IC2 is lower than 2.4V, D11 does not have breakdown and ends, and the 5 pin voltages of IC4 are that zero volt is ended, and LED does not work, and battery is surplus 2.4V voltage also, prevents the overdischarge of battery.
As shown in drawings, LED is luminous plaque circuit, selects the LED of the special high brightness of torch, and monolithic power is 3-5W, and operating voltage is 3.7V.
As shown in drawings, W is piezo-resistance, plays transient overvoltage protection; D8, D9 are the diodes of step-down, and the 5V voltage that IC1 exports is reduced 1.4V, with about 3.The voltage supply LED working power of 6V; R1, C1 form capacitance-resistance voltage reduction circuit, and V is rectifier, counnter attack charging diode during D3.C1 selects 224 models, and the pulsating current making rectifier V export about 80MA charges to battery; D10 is isolation and guiding diode.
