Abstract
The utility model relates to a non-circular section single spiral fluorescent lamp, which comprises a lamp tube, a cathode, a core column and a lamp cap, wherein the inner wall of the lamp tube is coated with a fluorescent powder layer. The cathode is fixedly connected with the core column which is tube-sealed at the end part of the lamp tube; the lamp cap is fixed outside the end part of the lamp tube. The utility model is characterized in that the section of the spiral lamp tube forms a non-circular shape which is elliptical or rectangular. Inert gases and amalgam are arranged in a lamp tube cavity; the amalgam is bismuth indium mercury or bismuth tin amalgam. The utility model has the advantages that the non-circular section single spiral fluorescent lamp has large thermal diffusion area and is easy to emit heat quantity when the lamp tube is turned on; the temperature of the lamp tube is reduced; the light efficiency and the luminous stability are kept.
Description
Technical field
The utility model relates to a kind of fluorescent lamp, particularly a kind of on-circular cross-section single-screw fluorescent lamp.
Background technology
Spiral fluorescent lamp is widely used in illumination because of energy-conservation and volume compact at present, and the surface of the light tube temperature is higher during spiral fluorescent lamp work, the high light efficiency and the stability of photoluminescence that can influence fluorescent lamp of surface of the light tube temperature.Existing spiral fluorescent lamp fluorescent tube cross section is generally circular, is easy to diffusion in order to make circular cross-section fluorescent tube heat, and general the employing increases the tube helix tube pitch, and distance between the spiral is increased, and the fluorescent tube heat is spread easily.But the spiral fluorescent lamp volume of this structure is bigger, and fluorescent tube integral body becomes loose, and moulding is not compact, uses inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is the existing in prior technology defective, adopting a kind of fluorescent tube cross section is the shape structure of non-round class, can be under the condition that does not increase the tube helix tube pitch, the fluorescent tube heat is spread easily, noncircular sectional shape is oval, or be rectangle, on-circular cross-section spiral fluorescent lamp fluorescent tube has big heat diffusing surface, and the heat when being easy to the fluorescent tube burning-point distributes.The utility model design on-circular cross-section single-screw fluorescent lamp, comprise fluorescent tube, negative electrode, stem stem, lamp holder, tube inner wall is coated with and is equipped with phosphor powder layer, negative electrode is fixedlyed connected with stem stem, stern column is encapsulated in lamp tube end, the lamp tube end external fixation has lamp holder, it is characterized in that: the helical lampl cross section is a non-circular shape, and non-circular shape is oval, or is rectangle, the fluorescent tube chamber is built-in with inert gas and mercury alloy, mercury alloy is a bismuth indium mercury, or be the bismuth tin-mercury alloy, the utility model has the advantages that on-circular cross-section single-screw fluorescent lamp has big heat diffusing surface, the heat when being easy to the fluorescent tube burning-point distributes, lamp hole temperature is reduced, keep light efficiency and stability of photoluminescence.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model elliptical lamps tube section shape;
Fig. 3 is the utility model rectangle fluorescent tube cross sectional shape.
Among the figure: 1 is that fluorescent tube, 2 is that negative electrode, 3 is that stem stem, 4 is lamp holder.
Embodiment
With reference to Fig. 1, the utility model comprises fluorescent tube 1, negative electrode 2, stem stem 3, lamp holder 4, and fluorescent tube 1 is the single-screw fluorescent lamp, it is characterized in that: helical lampl 1 cross section is non-circular, negative electrode 2 is fixedlyed connected with stem stem 3, stem stem 3 pipes are encapsulated in fluorescent tube 1 end, and fluorescent tube is equipped with lamp holder 4 outside 1 end, in fluorescent tube 1 chamber, fluorescent tube 1 inwall is coated with and is equipped with phosphor powder layer, and be equipped with inert gas and mercury alloy, the mercury alloy pipe injects in the tube chamber, maybe can place the lamp tube end blast pipe.
Fluorescent tube on-circular cross-section described in the utility model is oval, or is rectangle, shown in Fig. 2-3.
The utility model fluorescent tube is the single-screw type, and spiral spacer is equidistant, also can spiral spacer for not equidistant.The non-round helical lampl of the utility model has big heat diffusing surface, and lamp hole temperature is reduced, and keeps light efficiency and stability of photoluminescence.
