Description

The AC/DC electronic energy-saving lamp

The utility model relates to a kind of AC/DC illuminating lamp.

Wretched insufficiency below existing Dual-purpose dc/a.c lamp exists: 1, adopt incandescent lamp to do light source more, because power consumption is big during direct current supply, make the stand-by power supply power-on time short, and filament easily blows, service life is short; 2, be fit to effectively to use when civilian emergency light has only civil power to interrupt usually, and just often can not work, cause the inconvenience in the use in mains-supplied; 3, the dual-purpose illuminating lamp that has be actually two separately independent device, not only increased manufacturing cost, also increased light fixture and taken up space; 4, the dual-purpose lamp that has adopts relay to make AC-DC conversion switch, and mechanical breakdown easily takes place, and service life is short; 5, do not have complete mistake charge and discharge protection mostly, make the service life of batteries short.

The purpose of this utility model is to provide that a kind of power saving, cost are low, easy to operate, the AC/DC electronic energy-saving lamp of long service life.

Structure square frame of the present utility model as shown in Figure 1, its principle is as shown in Figure 2.Below in conjunction with accompanying drawing the utility model is described in detail.

The utility model is by alternating electron change-over switch 1; the capacitance-resistance lotus root is closed rectifier 2; additives for overcharge protection and indicator 3; batteries 4; control protector 5; oscillator 6; electric ballast 7; power saving fluorescent lamps 8 is formed; wherein civil power is through fuse BX1; one the road links alternating electron change-over switch 1; another road is linked the capacitance-resistance lotus root and is closed rectifier 2 and link additives for overcharge protection and indicator 3 again; control protector 5 is linked in the output of one road; batteries 4 is linked on another road; batteries 4 and control protector 5; oscillator 6 also connects, and the output of alternating electron change-over switch 1 and oscillator 6 is linked electric ballast 7 respectively and linked power saving fluorescent lamps 8 again.

Alternating electron change-over switch 1 of the present utility model is made up of K switch 1, diode D1-D4; The capacitance-resistance lotus root is closed rectifier 2 and is made up of diode D5-D8, resistance R 1, capacitor C 1; Additives for overcharge protection and indicator 3 are made up of trifocal integrated regulator IC1, triode T1, diode D9-D10, Zener diode W1, LED-G (green) and LED-Y (Huang), resistance R 2-R4; Control protector 5 is made up of K switch 2, triode T2-T4, diode D11-D12, Zener diode W2, resistance R 5-R8, capacitor C 4.

Alternating electron change-over switch 1 and capacitance-resistance lotus root are closed in the rectifier 2, civil power is through fuse BX1, one the tunnel through K switch 1 link by D1-D4 institute structure rectifier link respectively again A, B the end, another road through R1, C1 parallel circuit link by D5-D8 institute structure rectifier link respectively again C, D the end; In additives for overcharge protection and the indicator 3, the IC1 input is linked C end and output and D9, D10 and each positive pole of LED-Y, R2 and is attached to the F end, W1 and T1 base stage, the R4 that D9 negative pole warp oppositely connects also connects, the LED-Y negative pole is through R3 and T1 colelctor electrode, LED-G positive pole, the R2 other end and connect, the D10 negative pole is linked the G end, and IC1 common port and T1 emitter stage, LED-G negative pole, the R4 other end also attach to the D end; In the control protector 5; 1 of K2 links 4,2 and links G, 3 and link T2 emitter stage, 5 and link C4 positive pole, 6 and T3 base stage, W2 positive pole, R6 and connect; the T2 base stage is linked the T3 colelctor electrode through R5; D11 and T2 colelctor electrode, the T4 emitter stage that W2 negative pole warp oppositely connects also connects; T4 base stage and D12 negative pole, R7 also connect; the D12 positive pole is linked the F end, and the T4 colelctor electrode is linked transformer B1 base stage winding centre cap through R8, and T3 emitter stage and R6 and the R7 other end, C4 negative pole also attach to the D end.

Operation principle of the present utility model is as follows: civil power one tunnel is through Closing Switch K1, link A, B end respectively via D1-D4 institute structure rectifier again, make the electric ballast work that is constituted by triode T7-T8, diode D17-D20, resistance R 9-R14, capacitor C 6-C9, transformer B2 and B3, power saving fluorescent lamps 8 is obtained high frequency voltage and rapid build-up of luminance from C8, disconnect K1, light fixture quits work; Another road of civil power is through R1, the C1 parallel circuit, again via D5-D8 institute structure rectifier, again by IC1 output stablizing DC voltage, the D10 of leading up to carries out the over-charge protective charging to batteries E, another road ends T4 by D12, no matter what position is K switch 2 be in, the biasing circuit that all causes oscillator 5 is obstructed and do not work, thereby guarantee the operate as normal of light fixture when faulty operation appears in Alternating Current Power Supply and K2, when E is not filled electricity, W1 can not be reversed puncture, causes T1 to end, and makes LED-G bright, the little bright indication charging of LED-Y, when E is filled electricity (charging is ended), W1 is reversed puncture, causes the T1 saturation conduction, and LED-G is gone out, the bright indication charging of LED-Y is ended; When civil power interrupts, K2 is pulled to 0N, the C4 that is recharged triggers the T3 base stage, make the T3 conducting, because T2, the amplification of T3, make T2, the rapid saturation conduction of T3, E again through the T4 of conducting, make the biasing circuit of oscillator 6 connect and work through T2, its output is linked A respectively through D13-D16 institute structure rectifier, the B end, the working power of electric ballast when substituting Alternating Current Power Supply owing to the unidirectional on state characteristic of D1-D4 and each bridge circuit that constitutes of D13-D16, has guaranteed the operate as normal of light fixture AC/DC, K2 is pulled to OFF, light fixture quits work, and E connects the charging to C4 by K2, for next direct current supply work is prepared; In direct current supply, when the terminal voltage of batteries drop to its rated value 85% the time, W2 can not be reversed to puncture T3 is ended, and causes T2 to end, and makes the biasing circuit of oscillator 5 obstructed, thereby light fixture is quit work automatically; Use for convenience, respectively separately with A, B two places, the left side is the power supply part, the right is load, when a plurality of load of needs, as long as substitute A, B two places (each load input will be installed fuse and filter capacitor) with two long lines respectively, just constitute one with the common two wires corresponding to two bus centralized control systems of throwing light on.From on can find out that control protector 5 is that the biasing circuit by control T5, T6 plays a protective role, not only loss is little, and does not lose the operating voltage of E, again owing to adopted electric ballast and power saving fluorescent lamps, makes the light fixture economize on electricity obviously.

The utility model power saving, low, easy to operate, the long service life of cost.
