Abstract
Disclosed is an alternating-current LED bulb lamp which is composed of a simple circuit structure and a small amount of electronic elements. An LED is driven directly by alternating current to emit light, so that electric energy loss caused by converting alternating current to direct current is reduced; positive and negative half waves of alternating current are utilized to alternately drive two groups of LED lamp strings respectively, so that energy saving efficiency of the LED bulb lamp is improved. Due to comprehensive measures, electricity saving efficiency of the alternating-current LED bulb lamp is improved by more than 30% when compared with those of similar bulb lamps.
Description
Technical field
The present invention relates to a kind of LEDbulb lamp exchanging AC.
Background technology
LEDbulb lamp popular on market, being all, by rectification circuit, alternating current is become the work of DC powered LED luminous plaque, is namely all the LEDbulb lamp of direct current DC.The LEDbulb lamp of direct current DC, become in galvanic process in interchange, and energy loss about 20%, makes the fractional energy savings of LEDbulb lamp there is no abundant raising.
Summary of the invention
The present invention discloses a kind of LEDbulb lamp exchanging AC, its circuit is simple, element is little, the light-emitting diode of the positive and negative half-wave Direct driver two groups utilizing alternating current reverse wiring each other, namely utilize light-emitting diode to have the feature of single-phase conductivity, reduce alternating current and become electric loss of energy in galvanic process; Utilize again two positive and negative voltages of alternating current LED group different in two wiring directions respectively to take turns to operate, thus save part electric energy.The electricity-saving rate of the LEDbulb lamp of a kind of AC of interchange is caused to improve more than 30% than the fractional energy savings of the LEDbulb lamp of direct current DC.
A novel light-operated LED bulb lamp, its circuit composition is made up of electronic transformer circuit filtering circuit and LED luminous plaque.
Accompanying drawing explanation
Accompanying drawing is a kind of circuit theory diagrams exchanging the LEDbulb lamp of AC.
Embodiment
As shown in drawings, R1, R2, R3, C1, D1, D2 are electronic transformer circuit, and input is 220V alternating voltage, and output is the alternating voltage reducing some volts.Then directly lumination of light emitting diode is driven by alternating current.D1 is bidirectional diode, and D2 is bidirectional thyristor.
As shown in drawings, LED lamp bead is concatenated into two groups of reverse each other lamp strings.If when alternating current is positive half wave, then the LED string that L1 is capable is that forward is worked out and conducting, and the LED truncation that L2 is capable stops, and conducting loop is L-D2-L1-LED-R4-N; If when alternating current is for negative half-wave, then the LED string that L2 is capable is that forward is worked out and conducting, and the LED truncation that L1 is capable stops, and conducting loop is N-R4-L2-LED-D2-L.L1, L2 in accompanying drawing are inductor filter circuit, the characteristic utilizing inductance to have electric current can not to suddenly change, and filtering part alternating current reduces the stroboscopic of LED lamp bead.
As shown in drawings, V is piezo-resistance, plays overvoltage protection in circuit, and R4 is current-limiting resistance, current value is limited in certain value.
