The purpose of this utility model is to remedy the deficiencies in the prior art, and a kind of long-life fluorescent tube of easy to use, stable performance is provided.
The purpose of this utility model adopts following measure to finish:
This fluorescent tube is by glass shell, metal end, fixedly lamp base, filament are formed, it is characterized in that, on the metal end of existing lamp tube ends, respectively be provided with a jack and two rivets, copper contact blade is respectively arranged on the rivet, two filaments respectively are equipped with at two ends in fluorescent tube, one on filament on each end is connected with fixing lamp base, the other end each be fixed on metal end on rivet be connected, jack is made by tubular rivet, in jack, be inserted with the formula lamp base, one copper contact blade arranged at the middle part of inserting the formula lamp base; Also can be provided with the jack identical with the filament radical on metal end, one on the filament in the fluorescent tube is connected with fixing lamp base, and the other end respectively connects a jack, will not have in the slotting formula lamp base insertion jack of copper contact blade; Also can on the end face of lamp tube ends metal end, respectively be provided with two fixedly lamp bases, on the anchor ring of metal end, be provided with filament switch, filament switch is by slide plate, slideway, card base, insulation board, rivet is formed, rivet has copper contact blade, insulation board is fixed on the anchor ring of metal end with rivet, the rivet both sides is provided with slideway, slide plate slides on slideway by its card base, slide plate is to make with metal, be used to connect the copper contact blade on the rivet, filament one end is connected with rivet in the fluorescent tube, the other end with one fixedly lamp base be connected, establish again a rivet with another fixedly lamp base be connected, when slide plate is connected the rivet of filament and copper contact blade on the rivet that is connected and fixed lamp base contacts with one, fluorescent tube illumination, when treating that disintegration of filament can slide into slide plate copper contact blade contact on the rivet that is connected filament with another, fluorescent tube just can continue to throw light on.
Also can three filaments respectively be set two ends in fluorescent tube, the rivet that connects filament is identical with the filament radical, and other structures are constant.
The utility model is owing to be equipped with two filaments in lamp tube ends, therefore work as another filament of disintegration of filament and can take over use, thereby prolonged fluorescent tube useful life, and all supporting uses of various ballasts, starter, lamp bracket that can use with existing fluorescent tube have simple, stable performance, advantage such as easy to use are installed.
