Abstract
The utility model provides an electronic ballast for daylight lamps, which is mainly composed of a machine case, a circuit board, a rectifying filter pulse circuit A and a current limiting circuit B. The circuits A, B are installed on the circuit board and the circuit board is installed in the machine case. Compared with the prior art, the utility model has the advantages of simple structure, low cost, easy installation and utilization, no stroboflash, electric energy saving, prolonged service life of a daylight lamp tube, etc.
Description
The utility model relates to a kind of lighting device, specifically a kind of electronic ballast for fluorescent lamp.
We mainly contain two classes by fluorescent lamp ballast used in everyday: a kind of is Inductive ballast, and another kind is an electric ballast.Inductive ballast has problems such as consuming energy greatly, be easy to generate noise and fluorescent tube weak point in useful life, is replaced by electric ballast gradually at present.But also there are problems such as circuit complexity, cost height, useful life be short in existing all kinds of electric ballast, still awaits further solution.
The purpose of this utility model provide a kind of circuit simple, be easy to make, cost is low, the life-span is long, the electronic ballast for fluorescent lamp of noiselessness, no stroboscopic.
The purpose of this utility model realizes in the following manner, adopts two rectifier diodes and two capacitance group to become full-wave rectification two multiplication of voltage capacitor filters and two resistance two-way current-limiting circuit, provides two stable multiplication of voltage voltages to fluorescent tube, and it is lighted.
Figure of description 1 is circuit theory diagrams of the present utility model.
Figure of description 2 is a schematic block circuit diagram of the present utility model.
Figure of description 3 is ballast overall structure figure of the present utility model.
The utility model will be further described with reference to Figure of description.
Electric ballast of the present utility model is mainly by casing (1), circuit board (2) and rectification Filtering impulse circuit A, current-limiting circuit B form. Circuit A, B are installed on the circuit board, and circuit board (2) is installed in the casing (1). Rectifying and wave-filtering impulse circuit A is by commutation diode D1、D
2, filter capacitor C1、C
2Reach the parts compositions such as K switch, power for illumination a end in city meets D by K1Anodal D2Negative pole, C1、C
2Be serially connected in D1Negative pole and D2Positive pole between, city power for illumination b termination C1、C
2Serial connection point on, R1Be serially connected with D1Between negative pole and the fluorescent tube, R2Be serially connected with D2Between positive pole and the fluorescent tube.
Embodiment:
