Abstract
The utility model relates to an electronic ballast, particularly a glow starter capable of illumining a fluorescent lamp when lamp filaments of the fluorescent lamp are broken. The glow starter comprises a bridge rectifier circuit composed of diodes, a filter circuit taking an electrolytic capacitor as a primary element, and a high-frequency circuit. Another electrolytic capacitor with the same parameters is connected in series to the electrolytic capacitor in the filter circuit. Because the technical proposal is used, the utility model has the advantage of long service life. The fluorescent lamp can also be illumined when the lamp filaments of the fluorescent lamp are broken.
Description
The utility model relates to a kind of electronic ballast device, particularly a kind of starter that also it is lighted when Filament of fluorescent lamp is disconnected.
In the prior art, electric ballast generally is made up of rectification circuit, filter circuit and high-frequency circuit, when filament is disconnected, with lead the fluorescent lamp bipod is coupled together, fluorescent lamp can be lighted, but the very fast meeting of the electrochemical capacitor in the electric ballast is burnt out, make it produce the deficiency that useful life is short, waste resource, useful life, short main cause was that element is unworthy of fitting, and caused concentration of energy and impact, caused element heating to burn out.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of starter that also it is lighted when the fluorescent tube filament is disconnected is provided.
In order to achieve the above object, the utility model provides a kind of new technical solution: this starter comprises the bridge rectifier that is constituted by a diode, by the filter circuit and the high-frequency circuit that with the electrochemical capacitor are main element, and in filter circuit electrochemical capacitor that parameter is identical of series connection on the electrochemical capacitor.
Owing to adopted technique scheme, made the advantage that the utlity model has long service life when Filament of fluorescent lamp is disconnected, it is lighted.
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing and concrete execution mode essentiality content of the present utility model is described in further detail.
Among the figure, this starter comprises the bridge rectifier be made up of diode D1-D4, by being the filter circuit and the high-frequency circuit of main element with electrochemical capacitor C, and electrochemical capacitor C3 that parameter is identical of series connection on the electrochemical capacitor C2 in filter circuit.In traditional electric ballast, when tube filament blows, with lead lamp base is linked up, this moment, lamp can be lighted, but the very fast meeting of electrochemical capacitor C1, C2 is burnt out, behind the electrochemical capacitor C3 that connected, various element noenergy in the circuit are concentrated and are impacted, and can not cause superheating phenomenon, the electric current smooth working in the entire circuit, can bear because of filament blow links up the abnormal conditions that produce to lamp base with lead, thereby improve the useful life of fluorescent tube.
