Double-helix energy-saving fluorescent lamp tube and energy-saving fluorescent lamp

Abstract

The invention discloses a double-helix energy-saving fluorescent lamp tube, which comprises a spiral main body section wound around a longitudinal axis and a linear tube foot section bent inwards radially, and is characterize in that: a linear connecting section is arranged between the main body section and the linear tube foot section; the linear connecting section extends linearly along the tangent passing through the end point of the helix on the main body section; a circular arc transitional section is arranged between the linear connecting section and the linear tube foot section; the length of the linear connecting section is more than or equal to the diameter of the lamp tube and smaller than or equal to the helix diameter of the last circle of the main body section; in the energy-saving fluorescent lamp tube based on this, the upper end face of a lamp holder is provided with a lamp tube connecting seat which has a connecting hole; and the linear tube foot section is inserted into the connecting hole and adhesive for connecting the double-helix lamp tube and the lamp holder is arranged in the connecting seat. The double-helix energy-saving fluorescent lamp tube has the advantages that: in processing and sealing processes, the contact between the head part of the lamp core and the inner wall of the glass tube is avoided, and the qualification rate of the product is improved greatly; the assembly is convenient, the processing efficiency is improved; and the industrialization of the energy-saving fluorescent lamps with the structure can be realized easily.

Description

technical field [0001] The invention relates to an energy-saving fluorescent lamp tube, in particular to a double-helix energy-saving fluorescent lamp tube and an energy-saving fluorescent lamp. Background technique [0002] The traditional double-helix energy-saving fluorescent lamp tube is in the shape of a helix, and the shape of the pin connected to the lamp holder is consistent with the main body of the lamp tube. But in practice, it has been found that this type of double-helix energy-saving fluorescent tube is difficult to seal during processing. If you are not careful, the wick at the end of the lamp tube will contact the inner wall of the lamp holder, and the wick will easily be scrapped due to crooked wire. For this reason, a kind of double-helix energy-saving fluorescent lamp tube that is more convenient to seal is designed, and it is to arrange a straight-line tube foot section that bends inwards at the lower end of lamp tube, thereby has solved the above-mention...

Problems solved by technology

However, the discharge lamp assembly with the spiral structure also has shortcomings. The end of the spiral energy-saving fluorescent lamp tube is directly bent from the main helical section, and there is a large curved part between the straight end and the helical main section. , which greatly reduces the straight-line distance inside the end. At the same time, since the main body of the lamp holder needs to extend into the interior of the spiral structure, the straight-line distance inside the end is further reduced, and it is very easy to cause the head of the wick to touch the inner wall of the glass tube. This is especially true for some lamp tubes with relatively small screw diameters; when assembling with the lamp holder, it is necessary to make the main body of the lamp holder extend into the interior of the spiral structure, and ensure that the end can enter the lamp holder from the two side walls , it is not only necessary to accurately ensure the length of the end, but also to be very careful not to damage the lamp tube during installation. Pass rate is relatively low

This is also the reason why the products of this structure cannot be industrialized
