Abstract
The invention relates to a high-power single lamp bead or COB mobile LED stall lamp. A charging circuit, an overcharge and over-discharge prevention function, a single lamp bead or COB and a chip with the power from 3 to 10W form the lamp. The lamp has the overcharge and over-discharge prevention function. The light-emitting chip uses the single high-power LED lamp bead or COB as the lamp. The power is from 3 to 10W.
Description
Technical field
The present invention relates to the mobile LED stall with goods spread out on the ground for sale lamp of a kind of high-power single lamp pearl or COB.
Background technology
Current mobile LED stall with goods spread out on the ground for sale lamp, be all adopt series-parallel circuit type of attachment to form, its charging process has anti-overcharge Electricity Functional, but discharge process lacks anti-overdischarge function, make most of stall with goods spread out on the ground for sale lamp cause the charge function of battery to lose because of overdischarge, LED stall with goods spread out on the ground for sale lamp cannot be used; Be again stall with goods spread out on the ground for sale lamp when selecting low power plurality of LEDs lamp pearl to combine, because the work rate of lamp pearl is little, operating current is just burned slightly a little louder, and the spoilage of lamp pearl is very large.
Summary of the invention
A mobile LED stall with goods spread out on the ground for sale lamp of high-power single lamp pearl or COB, select powerful single LED lamp pearl or COB to be light emitter chip, its power is between 5-10W.The lamp housing of stall with goods spread out on the ground for sale lamp continues to use stall with goods spread out on the ground for sale lamp lamp housing popular on market; The electric circuit syndeton of stall with goods spread out on the ground for sale lamp is made up of the LED of charging circuit, switching circuit, single high-power lamp pearl or monolithic COB.
Accompanying drawing explanation
Accompanying drawing is the circuit theory diagrams of the mobile LED stall with goods spread out on the ground for sale lamp of a kind of high-power single lamp pearl or COB.
Embodiment
As shown in drawings, R1, C form capacitance-resistance voltage reduction circuit, and C selects the electric capacity of the dacron of withstand voltage more than 400V, and capacity is 224 or 474, and resistance-capacitance circuit reduces some volts alternating current 220V and sends to rectification circuit.Described rectification circuit is piled B by single-phase bridge rectification and is formed, and the capacity of rectistack B is 1A, the alternating current after step-down is become the direct current supply charging working power of pulsation.
As shown in drawings, D1, D2, R2 form anti-overcharge circuit, and D1 is both-end voltage-stabiliser tube, select 3.7V voltage stabilizing value.Before the rated voltage not reached battery by rechargable battery, D1 not conducting, battery continues to be charged, until when being full of electricity by rechargable battery, the breakdown and conducting of D1, battery no longer charges, and plays and prevents overcharge effect.
As shown in drawings, D4, IC form anti-overdischarge circuit, when charged battery, when pressing K switch, LED is bright, large-power LED light bead or the COB chip of LED to be single power be 3-10W, D4 is both-end pressurizer, selects 2.4V voltage stabilizing value, when battery power discharge voltage is lower than 2.4V, both-end voltage-stabiliser tube D4 becomes cut-off from conducting, and 5 pin of IC lose trigger voltage and end.IC is model is TWH8778 power switch chip, when the current potential of its 5 pin is lower than 1.6V, and 2, the 3 pin no-outputs of IC; When the voltage of 5 pin is higher than 1.6V, the voltage of its 1 pin moves on to 2,3 pin.When 5 pin voltages are lower than 1.6V, IC just closes, and stops battery discharge, plays anti-overdischarge function.
As shown in drawings, D2, D3 form charging display circuit, and at charging work condition state, the voltage of battery does not reach 3.7V, and D2 does not work, and D3 is bright, and display battery is in charged state; When battery is charged to 3.7V, D2 is breakdown, and electric current flows through from D2, and now D2 is bright, and D3 goes out, and represents that battery is full of electricity.Another of D3 makes of being anti-reverse charging electro ultrafiltration, prevents battery from carrying out reverse charge to charging circuit, and single high-power lamp pearl or COB chip during LED, power is at 3-10W.
Claims (3)
1. a mobile LED stall with goods spread out on the ground for sale lamp of high-power single lamp pearl or COB, its circuit connects and is made up of the LED of charging circuit, switching circuit, single high-power lamp pearl or COB.
2. a mobile LED stall with goods spread out on the ground for sale lamp of high-power single lamp pearl or COB, is characterized in that: stall with goods spread out on the ground for sale light fixture has during charging and has anti-overcharge function; Have anti-overdischarge function during electric discharge, and charging there is charging instruction and is full of electricity instruction.
3. a mobile LED stall with goods spread out on the ground for sale lamp of high-power single lamp pearl or COB, is characterized in that: the luminous plaque of stall with goods spread out on the ground for sale lamp selects the LED of single lamp pearl or COB type, power to be 3-10W.
