Abstract
The utility model discloses a spiral lamp tube for a fluorescent lamp, which is provided with a parallel dual-spiral lamp tube body and two lamp tube legs, wherein the lamp tube body and the lamp tube legs are connected in series, and the two lamp tube legs are positioned on the same end of the lamp tube body. The two lamp tube legs are inclined to the axis direction of the dual-spiral lamp tube. The two lamp tube legs of the spiral lamp tube for a fluorescent lamp are inclined to the axis direction of the dual-spiral lamp tube, so the total length of the lamp tube is shorten, the volume of a plastic casing of an amperite is reduced, and the lamp tube is not easy to be damaged during the manufacturing process of the lamp tube or a whole fluorescent lamp. The angles between the two lamp tube legs and the axis are equal, and the roots of two lamp tube legs are symmetrical to the center of the common end surface of the lamp tube body. The angles between the two lamp tube legs and the common end surface of the lamp tube body are complementary. The two lamp tube legs are crossed in different planes. The utility model has the advantages of easy production, high finished product rate, firm fixation and connection between the lamp tube and a lamp cap, and simple assembly.
Description
Technical field
The utility model relates to fluorescent lamp tube, particularly relates to a kind of fluorescent lamp tube for the parallel double helix shape that is connected in series.
Background technology
Existing a kind of spiral helicine fluorescent lamp tube, it has the fluorescent tube main body and two lamp pins of the double helix shape of parallel serial connection, and two lamp pins all are positioned at the common ends of fluorescent tube main body; The root of two lamp pins is symmetrical with respect to the center of the common end face of fluorescent tube main body, and the parallel axes of two lamp pins and fluorescent tube main body.This fluorescent lamp tube has following shortcoming: one, and the length overall of fluorescent tube is long; Its two, it is big that ballast is moulded shell volume; Its three, fluorescent tube is fragile in the fluorescent tube manufacture process or in the whole lamp manufacture process of fluorescent lamp.
The utility model content
The purpose of this utility model provides a kind of spiral helicine fluorescent lamp tube, it has solved the existing in prior technology problem, and the length overall of fluorescent tube shortens, ballast moulds that shell volume reduces, fluorescent tube is not fragile in the fluorescent tube manufacture process or in the whole lamp manufacture process of fluorescent lamp.
The utility model adopts following technical scheme: a kind of spiral helicine fluorescent lamp tube, fluorescent tube main body and two lamp pins with double helix shape of parallel serial connection, two lamp pins all are positioned at the common ends of fluorescent tube main body, and described two lamp pins all tilt to the axis direction of the fluorescent tube main body of double helix shape.
Described two lamp pin antarafacials intersect, and two lamp pins equate with angle between the axis.
The root of described two lamp pins is symmetrical with respect to the center of the common end face of fluorescent tube main body, and the angle complementation of the common end face of two lamp pins and fluorescent tube main body.
Described two lamp pins are symmetrical with respect to the axis of fluorescent tube main body.
Angle between described two lamp pins and the axis is all greater than-90 °, all less than 90 °.
Angle between described two lamp pins and the axis is 45 °.
The diameter of described fluorescent tube is less than 16 millimeters.
By above-mentioned description to the utility model structure as can be known, compare, the utlity model has following advantage with background technology:
One, spiral helicine fluorescent lamp tube of the present utility model, two lamp pins all tilt to the axis direction of the fluorescent tube main body of double helix shape, and the length overall of fluorescent tube shortens, ballast moulds that shell volume reduces, fluorescent tube is not fragile in the fluorescent tube manufacture process or in the whole lamp manufacture process of fluorescent lamp;
They are two years old, two lamp pins equate with angle between the axis, the root of two lamp pins is symmetrical with respect to the center of the common end face of fluorescent tube main body, the angle complementation of the common end face of two lamp pins and fluorescent tube main body, two lamp pin antarafacials intersect, and fluorescent tube is easily manufactured, the rate of finished products height, being fixedly connected firmly between itself and the lamp holder, assembling is simple.
Description of drawings
Accompanying drawing 1 is the front view of fluorescent lamp tube;
Accompanying drawing 2 is the vertical view of fluorescent lamp tube.
Embodiment
Be further described below in conjunction with 1,2 pairs of the utility model of accompanying drawing.
A kind of spiral helicine fluorescent lamp tube, as shown in Figure 1, 2, having the fluorescent tube main body 1 of double helix shape of parallel serial connection and the common ends that two lamp pins, 2, two lamp pins 2 all are positioned at fluorescent tube main body 1, two lamp pins 2 are all to the axis 11 directions inclination of the fluorescent tube main body 1 of double helix shape.
The diameter of fluorescent tube is less than 16 millimeters.
The root of two lamp pins 2 is symmetrical with respect to the center of the common end face of fluorescent tube main body 1; The angle complementation of the common end face of two lamp pins 2 and fluorescent tube main body 1; Two lamp pins, 2 antarafacials intersect, and two lamp pins 2 equate with angle between the axis 11, are 45 °.
The axis 11 of fluorescent tube main body 1, the root of two lamp pins 2 have defined a face, and this face is made as middle axial plane.Angle between two lamp pins 2 and the middle axial plane is respectively a and b.Wherein a and b are all greater than-90 °, all less than 90 °.In the present embodiment a=45 °; B=45 °.
In application: scribble phosphor powder layer on the inwall of fluorescent lamp tube, on the terminal part of two lamp pins 2 filament electrode is installed, also charged and discharged working media in the fluorescent lamp tube.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
