Description
The utility model relates to a kind of AC/DC charging lighting device.
The device that it is charge power supply that the chargeable lighting device that existing market is sold is with 220 volts of alternating currents, still be the dual-purpose charging device of charge power supply not with interchange or with the DC power supply, and its complex structure, easy care not, generally do not have and be full of electric automatic stop charge function, thereby be difficult for using, the herdsman who particularly is not suitable for vast pastoral area uses.
The purpose of this utility model to provide a kind of with in the pastoral area widely used sun-generated electric power be charge power supply simultaneously also can AC power as charge power supply, and it is simple in structure, easily use, have the automatic stop of being full of function, AC/DC charging lighting device simple in structure.
The technical solution of the utility model is: this apparatus features is that the input of circuit of three-terminal voltage-stabilizing integrated IC is the electrode input end of direct current, and the output of IC is through a current-limiting resistance R
2The base stage that connects a triode BG, the control end of IC is through a variable resistor R
tConnect the negative input of direct current; Cross-over connection has a resistance R between the control end of IC and output
1The electrode input end of direct current is through LED, resistance R
3The serial connection back connects the collector electrode of triode BG, and the emitter of triode BG connects the positive terminal that is recharged pond E, the negative pole end ground connection of battery E; The two ends of battery E also are serially connected with a K switch and a bulb D; Between the positive and negative electrode input of direct current, be parallel with one by transformer T step-down, the DC power supply of the AC-DC that rectification circuit ZL rectification forms.
Advantage of the present utility model and effect are: realized the function with two kinds of power source charges of alternating current-direct current, and having the function of the automatic stop function that is full of electricity, this apparatus structure is simple simultaneously, easily uses, easy care, the herdsman or the field worker that are particularly suitable for vast pastoral area use.
Fig. 1 is the utility model structural representation
As this device of Fig. 1 one a direct current power access end DC and an AC power incoming end AC are arranged respectively.When charging with DC power supply, direct-flow input end DC is inserted DC power supply, at this moment, dc signal behind circuit of three-terminal voltage-stabilizing integrated IC, forms a stable voltage V at its output more earlier through voltage-stabiliser tube DZ voltage stabilizing
o, and through resistance R
2BG provides bias current for triode.DC power supply is through LED, current-limiting resistance R simultaneously
3, be battery E charging through triode BG.Along with the carrying out of charging, cell voltage V
EConstantly raise, because V
oStablize constant, as cell voltage V
EBe elevated to the V that makes triode
BeDuring less than its conducting voltage, triode BG ends, and charging finishes automatically, and the LED breath goes out, and the indication charging finishes.Adjust the value of resistance R t and just can adjust V
oValue, exporting different reference voltages, thereby adapt to different batteries.R
1Be feedback resistance.When with alternating current power supply charging, with ac power input end AC incoming transport power supply, at this moment ac signal is through transformer T step-down, become dc signal through rectification circuit ZL rectification again, this signal is access in dc supply input, thereafter the course of work and the above-mentioned course of work when charging with DC power supply are identical, repeat no more.When using this device illumination, disconnect charge power supply, open K switch, bulb D is bright, can use.
