A kind of double-helix energy-saving fluorescent lamp and power saving fluorescent lamp
Technical field
The present invention relates to a kind of energy-saving fluorescent lamp, especially relate to a kind of double-helix energy-saving fluorescent lamp and power saving fluorescent lamp.
Background technology
Traditional double-helix energy-saving fluorescent lamp is helix shape, and shape and the fluorescent tube main body at it connects with lamp socket pin place are consistent.But it is found that in practice, the double-helix energy-saving fluorescent lamp of this form accidentally will cause the wick of fluorescent tube foot to contact with inboard wall of lamp holder to add man-hour sealing more difficult, easily because of askew, wick is scrapped.For this reason, a kind of sealing double-helix energy-saving fluorescent lamp comparatively easily is devised, and it is that a straight line pin section that bends inwards is set in the lower end of fluorescent tube, thereby has solved the problem of above-mentioned existence.No. 96104135.8 Chinese invention patents as the application of U.S. GE company disclose a kind of low-pressure discharge lamp assembly, its bulb forms the helical structure of reeling around longitudinal axis, and its end at helical structure one end radially curves inwardly from helical structure, two ends of bulb enter into the sidewall of the lamp socket that has respectively the first and second openings in the opposed part of lamp socket, its goal of the invention one is to reduce the bulb height, the 2nd, make electrode away from lamp socket, the 3rd, increase pulling capacity and save adhesive, the 4th, improve heat dispersion.But the discharge lamp assembly of this helical structure also exists weak point, the end of spiral energy-saving fluorescent tube is from the direct bending forming of main body spiral section, there is a larger crooked sweep between its straight line end and helical body section, greatly reduced the air line distance in the end, simultaneously, to stretch into the inside of helical structure due to the main body of lamp socket, therefore the air line distance in the end is further reduced, very easily cause the touching of wick head and glass-tube inwall, especially true for the fluorescent tube that some relative spiral shells footpaths is less; And when assembling with lamp socket, should make the main body of lamp socket can stretch into the inside of helical structure, to guarantee that also the end can enter lamp socket from the two side, this not only will accurately guarantee the length of end, also will be when mounted very carefully not break fluorescent tube, the assembly difficulty of its fluorescent tube processing and whole lamp is all very high, has also just caused working (machining) efficiency and qualification rate all lower simultaneously.This is also the reason place that the product of this structure can't form industrialization.
Summary of the invention
Technical problem to be solved by this invention is to provide and a kind ofly facilitates all higher double-helix energy-saving fluorescent lamps and provide a kind of lower to the fluorescent tube processing request of processing and working (machining) efficiency and qualification rate, and easy for installation, easily forms the power saving fluorescent lamp of industrialization.
the present invention solves the problems of the technologies described above a technical scheme that adopts: a kind of double-helix energy-saving fluorescent lamp, comprise the spirality main paragraph of reeling around longitudinal axis and the straight line pin section that radially bends inwards, be provided with the straight line linkage section between described main paragraph and described straight line pin section, described straight line linkage section extends along the tangent line straight line of the helix end points of described main paragraph, be provided with the arc transition section between described straight line linkage section and described straight line pin section, the length of described straight line linkage section is more than or equal to the diameter of fluorescent tube and less than or equal to the spiral shell footpath of described main paragraph last lap.
the present invention solves the problems of the technologies described above another technical scheme that adopts: a kind of power saving fluorescent lamp, comprise double helix tube and lamp socket, described double helix tube comprises the spirality main paragraph that longitudinal axis is reeled and the straight line pin section that radially bends inwards, be provided with the straight line linkage section between described main paragraph and described straight line pin section, described straight line linkage section extends along the tangent line straight line of the helix end points of described main paragraph, be provided with the arc transition section between described straight line linkage section and described straight line pin section, the length of described straight line linkage section is more than or equal to the diameter of fluorescent tube and less than or equal to the spiral shell footpath of described main paragraph last lap, the upper surface of described lamp socket is provided with lamp tube connection socket, be provided with connecting hole on described lamp tube connection socket, described straight line pin section is inserted in described connecting hole and is provided with the viscose glue that described double helix tube and described lamp socket are connected and fixed in the inside of described Connection Block.
Described lamp tube connection socket is projection on described lamp socket end face, and the opening of described connecting hole is relative with described double helix tube end face, and the inside of described lamp tube connection socket is provided with and holds the cavity that described straight line pin section is inserted.
Angle between described straight line pin section and described straight line linkage section is 30 ~ 95 degree.
Compared with prior art, the invention has the advantages that by the linearly extended straight line linkage section of tangent line along the helix end points of main paragraph of certain-length is set between main paragraph and straight line pin section, and between straight line pin section and straight line linkage section, the arc transition section is set, can guarantee the air line distance of straight line pin intersegmental part like this, make to be difficult for causing wick head and the touching of glass-tube inwall in processing sealing process, therefore can greatly improve the qualification rate of product; And be provided with the lamp tube connection socket of connecting hole by the upper surface at lamp socket, straight line pin section is inserted in connecting hole and by the viscose glue of Connection Block inside, double helix tube and lamp socket is connected and fixed, can be convenient for assembly, raise the efficiency, easily form the industrialization of the power saving fluorescent lamp of this structure.And lamp tube connection socket projection on the lamp socket end face, the opening of connecting hole is relative with the double helix tube end face, make only need when installing with fluorescent tube or lamp socket around longitudinal axis a little work rotate rectilinear tubes pin section is inserted in connecting hole easily.
