Abstract

The utility model relates to a fluorescent tube, which can restart to work after brightness is reduced and filaments are fused because of aging phosphors after the fluorescent tube has worked for a long time. An upper filament, a leading-out wire, a heat insulation and conduction board, a lower filament, a leading-out wire, a core pillar is arranged in the glass tube of the fluorescent tube in order. The fluorescent tube has four or three leading-out wires and is equipped with switch-transfer outside the glass tube.

Description

Double-deck two filament florescent lamp pipe

(1) technical field under

The utility model relates to all fluorescent tubes, and it can carry out starting the second time luminous under the situation that brightness of illumination reduces and filament fuses of fluorescent tube.

(2) background technology

Present fluorescent tube is that glass tube is arranged, fluorescent material, and filament, lead-out wire, lamp holder, lamp base is formed.

Supply voltage when fluorescent lamp starting, through ballast, filament is heated filament, and quite high self induction electromotive force of moment while ballast two ends generation is added in lamp tube ends after it and current/voltage are connected, and makes gas ionization formation arc discharge in the fluorescent tube.When fluorescent tube is wearing out easily near near the fluorescent material the filament under the long-term frequent starting, cause fluorescent tube two ends blackout, brightness reduction and filament hold disconnected.

(3) summary of the invention

In order to overcome traditional fluorescent lamp tube under frequent starting, fluorescent tube two ends blackout is utilized the second time after brightness reduction and the filament fusing.

The technical solution adopted for the present invention to solve the technical problems is pulled by adorning a heat insulation heat conduction before the filament at fluorescent tube two ends, increases by one group of filament more forward.Make the every end of fluorescent tube be divided into bilayer, every layer of one group of filament.When the ground floor filament is worked; moment is sent the heat energy that influences near the fluorescent material of filament during each the startup, pulls the resistance shelves for heat insulation heat conduction, sheds along thermal hole; it can prolong near the useful life of the fluorescent material of ground floor filament, also protects near the fluorescent material of second layer filament simultaneously.

When the fluorescent material of ground floor filament fusing back or fluorescent tube is aging, when brightness is reduced, can arrive second layer filament by switch transition.It has two kinds of four lead-out wires and three lead-out wires.

The invention has the beneficial effects as follows that it increases little portion of element on the basis of former fluorescent tube, can recover to use when brightness reduces or after the filament fusing and can economize on electricity with energy-conservation.
