Abstract

The utility model relates to a fluorescent lamp tube, in particular to a surface-type fluorescent lamp tube which is used for manufacturing a ceiling lamp and has higher power. The fluorescent lamp tube is a plum-shaped planar or umbrella surface-type fluorescent lamp tube which comprises a plurality of variable U-shaped powder coated tubes which are spliced through hot melting. The fluorescent lamp tube can comprise a continuous one branch lamp tube or comprise a plurality of discontinuous branch lamp tubes which are combined together. The lamp tube is formed by bending a straight glass tube into petals, coating powder in the tube and splicing a plurality of powder coated petal units through hot melting. The structure not only overcomes the defects of the prior art that first the power needs to be coated in the straight glass tube and then the tube is bent in high-temperature flame, so that the performance of the fluorescent powder is damaged at high temperature; in addition, because the irradiating area is enlarged, the plum-shaped fluorescent lamp has the advantages of large light-emitting surface, uniform light sources of the light-emitting surface and high luminous flux. The umbrella surface-type fluorescent lamp tube also makes an electronic ballast away from the light sources of the lamp tube, and facilitates the prolonging of the service life of the electronic ballast.

Description

A kind of novel suction end face type fluorescent tube

Technical field

What the utility model was related is a kind of novel suction end face type fluorescent tube, and the fluorescent tube of especially a kind of more powerful plane or umbrella cover type, this fluorescent tube can be one, also can be combined by branch.

Background technology

Inhale end face type fluorescent tube, moulding all is the two D shape fluorescent tubes in plane annular fluorescent tube or plane usually.Because the bending of fluorescent tube is many in annular lamp tube or the two D shape fluorescent tube, be difficult to directly coating fluorescent powder in the moulding glass-tube; Usually way is after the dusting, again with straight glass tube thermoplastic in flame, to curve annular or two D shape in straight glass tube.After this first dusting in the system lamp operation of heat bend pipe, the fluorescent material that has applied is subjected to temperatures involved in bend pipe, can cause the performance change of fluorescent material, and the light efficiency of fluorescent lamp is adversely affected, after particularly fluorescent tube used a period of time, light decay will be very serious.Secondly, common annular or two D shape fluorescent tube, because light-emitting area is single, light-emitting area is inhomogeneous, brightness is low, can form the fluorescent tube blackening, influences attractive in appearance.Moreover, pure flat lamp tube structure, fluorescent tube plane and rectifier close together, the heat that fluorescent tube produces can influence the useful life of electron rectifier.

Summary of the invention

Innovation and creation purpose of the present utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of light-emitting area even, and surface of light source is luminous full, and the light decay influence is little, and the light efficiency height can effectively prolong the electron rectifier novel suction end face type fluorescent tube in useful life.

Innovation and creation scheme of the present utility model is such: this fluorescent tube is to become U-shaped by many to be coated with tube cell, and promptly plum blossom flap pipe melts the plum blossom shape fluorescent tube that splicing is formed through heat.Plum blossom shape fluorescent tube wherein is coated with tube cell by the change U-shaped more than 5 or 5 and fuses and form; Plum blossom shape fluorescent tube both can have been fused by adjacent petal-shaped pipe series connection and be one, also can be formed by adjacent several petal fluorescent tube arm common combinations; Plum blossom shape face type fluorescent tube can be a plane, also can be the umbrella cover type that petal is upturned, and the angle of perk is less than 30 degree.

Change the face type fluorescent tube of existing annular or two D shapes into plum blossom shape face type fluorescent tube of the present utility model, so both satisfy high-power, long fluorescent tube, undersized shape-designing requirement, can remedy first dusting, back heating again, bend pipe influences the fluorescent material performance defect again.

Plum blossom shape face type fluorescent tube of the present utility model can be coated with tube cell by the change U-shaped more than 5 or 5 and fuse and combine.Here said change U-shaped is not meant the standard U-shaped of feet on parallel lines, and is meant and has bent to petal-like distortion U-shaped; Said type singly do not refer to plane, comprises the umbrella cover type that the petal arm of fluorescent tube is upturned yet, but the angle of perk is less than 30 degree.In addition, can also look the watt level of lamp, both can make the series connection of adjacent petal and fuse single tubes, also can make by the parallel group fluorescent tube of forming of a plurality of interruption tubes into one.Make the fluorescent tube of the utility model product, preferably selecting the caliber model for use is the glass-tube of T4, T5, T6.

Embodiment

Embodiment 1, and as shown in Figure 1, this is the schematic diagram of the plane plum blossom shape fluorescent tube in the utility model.It is by 6 the petal-shaped fin tube unit 1, unit 2 etc. of dusting, adjacent pin 3 grades is fused continuous, is connected in series and is one, and only tubes of being formed is connected to electrode 4 respectively at the two ends of fluorescent tube, and this moulding fluorescent tube can adopt the T4 pipe to make.

Embodiment 2: as shown in Figure 2, this is the split type form of expression of the present utility model.Fluorescent tube constitutes jointly by 5.1 and 5.2 two, and each is fused by three petal-shaped fin tube units in series respectively and forms, and this moulding fluorescent tube can adopt the T5 pipe to make.

Embodiment 3: as shown in figures 1 and 3.When fusing each petal-shaped fin tube unit, overall lamp control can be caused the fluorescent tube of umbrella cover type, being about to each petal-shaped fin tube unit is upturned, thereby the umbrella cover that makes whole plum blossom shape fluorescent tube is horizontal by the angle less than 30 degree, carry out fusing of each petal-shaped fin tube unit again, can finish, this moulding fluorescent tube can adopt the T6 pipe to make.
