Abstract

The utility model relates to a energy-saving lamp tube with two U-shaped curves in same plane, comprising a U-shaped glass tube (2), an emitter arranged on the end of the glass tube, a phosphor layer arranged on the inner wall of the glass tube (2), a core stem (5) arranged on the emitter, a tungsten filament (3) and a conductor (6), which is characterized in that the U-shaped glass tube is constructed through that the same glass tube is bent to two U-shaped curves continuously in same plane, then the whole glass tube is provided with three curves and two ends, on which the emitter is arranged; a hydrargyrum cavity (7) is arranged on the middle curves, and an indium netting (4) is arranged between the core stem (5) and the tungsten filament (3). The utility model is specially used as matching lamp tube for energy-saving lamp in the field of lighting and upholstery. Compared with the prior art, the utility model has the advantages of no dark for lighting, uniform emanation of hydrargyrum steam, long service life, great lamp tube starting and other excellences.

Description

Connect curved plane two U abnormity power saving fluorescent lamps

Technical field

The utility model relates to a kind of electronic energy-saving lamp tube.

Background technology

On market, rare plane two U power saving fluorescent lampss occur, Zhejiang Lin'an Qianshi Lighting Appliance Co., Ltd. once produced plane two U power saving fluorescent lampss, it is to be arranged by two single U-shaped pipe isoplanars, and passing a bridge connects, and two tack and two emitting heads are at homonymy, emitting head is close in the mercury chamber, indium net sheet is not installed on the stem stem, because of the existence of gap bridge is arranged, is influenced the luminosity of the outer fluorescent tube section of passing a bridge between two single U-shaped pipes; As the U-shaped fluorescent tube, the best section of luminosity is the curve bend section, and poor near the two ends section luminosity of emitting head and tack, therefore this two tack and two emitting heads are in a side, and two curve bend sections cause the imbalance of luminosity in the structure of opposite side; Emitting head is close in the mercury chamber, and is near from this high-temperature region of tungsten filament, and the thermal evaporation of mercury chance is fast, influences useful life; Indium net sheet is not installed on the stem stem, is not possessed the function that heat is put the enfleurage mercuryvapour, the open-minded weak effect of fluorescent tube.

Summary of the invention

At the above-mentioned deficiency of prior art, the purpose of this utility model provides glass-tube of a kind of usefulness, and two U fonts of work are curved continuously on same plane, have three arcs that are divided into both sides curved, two terminations; Two ends is an emitting head, no tack, do not have to pass a bridge, thus luminosity equilibrium, solid-state mercury slow evaporation, long service life, open-minded fast company curved plane two U abnormity power saving fluorescent lamps.

Above-mentioned purpose realizes with following measure: it is made up of the emitting head of U-shaped glass-tube, this glass-tube end, the fluorescent bisque of glass-tube inwall, the stem stem that is installed in emitting head, tungsten filament, lead, its U-shaped glass-tube is two U fonts continuously by same glass-tube on same plane curved, the whole piece glass-tube has curved, two terminations of three arcs, two ends is an emitting head, on arc in the middle of the mercury chamber is positioned at is curved, between stem stem and the tungsten filament indium net sheet is arranged.

The also available following measure of above-mentioned purpose comes perfect: the diameter of said U-shaped glass-tube is that 6-8mm, length are 100-200mm; Said mercury chamber 7 is short and small protruding bubble shape.

The utlity model has do not have gaps bridge, design features such as no tack, mercury chamber place position away from the hot-zone, interpolation indium net sheet, thereby have no luminous dark angle, mercuryvapour distributes equilibrium, long service life, mercuryvapour heat are put cold receipts and are made the open-minded advantage such as get well of fluorescent tube.

Description of drawings

Accompanying drawing is the utility model structural representation.

Embodiment

The utility model is described in further detail below in conjunction with embodiment and with reference to accompanying drawing: the applicant has done the improvement of three aspects on the structure to existing plane two U power saving fluorescent lampss, the one, with two effective gap bridges of single U-shaped link into an integrated entity, have two arcs of homonymy curved, two tack, pass a bridge and change same glass-tube into and curve two U-shaped pipes that fuse, no tack on same plane continuously, do not have and pass a bridge, have three arcs to bend the structure of the both sides that are placed in, and make invention good brightness and distributing equilibrium.The 2nd, with the former mercury chamber that places the emitting head hot-zone move to away from the arc of hot-zone curved on, make mercury be unlikely to meet high hot excessive vaporization and influence useful life.The 3rd, add indium net sheet, heat is put cold receipts mercuryvapour, and favourable fluorescent tube is open-minded.U-shaped glass-tube of the present utility model 2 two ends are emitting head, and stem stem 5, tungsten filament 3, indium net sheet 4, lead 6 are installed on the emitting head, and mercury chamber 7 is installed in the arc of emitting head homonymy bends on 1, in the mercury chamber 7 of protruding blister solid-state mercury is arranged.The diameter 6-8mm of U-shaped glass-tube 2, length is 100-200mm.

Claims

1. plane two U abnormity power saving fluorescent lamps is bent by a company, form by the emitting head of U-shaped glass-tube (2), this glass-tube end, the fluorescent bisque of glass-tube (2) inwall, the stem stem (5) that is installed in emitting head, tungsten filament (3), lead (6), it is curved to it is characterized in that said U-shaped glass-tube is two U fonts continuously by same glass-tube on same plane, the whole piece glass-tube has three arcs to bend (1), two terminations, two ends is an emitting head, on arc in the middle of mercury chamber (7) is positioned at is curved, between stem stem (5) and the tungsten filament (3) indium net sheet (4) is arranged.

2. company as claimed in claim 1 curved plane two U abnormity power saving fluorescent lamps is characterized in that said U type glass-tube diameter 6-8mm, and length is 100-200mm.
