Abstract
The utility model relates to a fluorescent lamp tube and provides an elliptical fluorescent lamp tube. The cross section of the lamp tube presents an ellipse shape. Compared with the lamp tube with the round cross section, the luminous efficiency is obviously enhanced. Compared with the lamp tube with the rectangle or annular cross section, the production process is simple, and the production and manufacture is easy. The utility model has the principle that under the condition that the area of the cross section is the same with that of the round cross section, the luminous area of the elliptical lamp tube is larger than the luminous area of the round lamp tube, and therefore, the luminous efficiency of the elliptical lamp tube is higher than the luminous efficiency of the round lamp tube.
Description
Technical field
The utility model relates to a kind of fluorescent tube.
Background technology
The fluorescent tube cross section of conventional fluorescent fluorescent tube is circle, rectangle, annular, and its shortcoming is: cross section is little than the lamp tube current density of other shape because of flowing through lamp tube current density for circular fluorescent tube, and causes luminous efficiency lower; Increase though rectangle and annular luminous efficiency are circular, production technology is comparatively complicated.
Summary of the invention
The utility model provides a kind of oval fluorescent tube, and the cross section of its fluorescent tube is oval, and luminous efficiency obviously improves for circular fluorescent tube than cross section, and production technology is simple than rectangle or annular, is easy to manufacture.
Under the round lamp tube situation identical with the cross-sectional area of oval fluorescent tube, promptly under the situation that the current density in the fluorescent tube is identical, the girth of the cross section of oval fluorescent tube is longer than the girth of round lamp tube cross section.In other words, under the situation identical with circular cross-sectional area, the light-emitting area of oval fluorescent tube is bigger than the light-emitting area of round lamp tube.Thereby the luminous efficiency of oval fluorescent tube is higher than circular.
Description of drawings
Accompanying drawing is the cross sectional representation of fluorescent tube.
Embodiment
Fluorescent tube internal diameter is 15 millimeters a circular fluorescent fluorescent tube, and the girth of its cross section is about 47 millimeters.A major axis is 38 millimeters, and minor axis is that 6 millimeters the cross-sectional area of oval fluorescent tube is suitable with it, and the girth of fluorescent tube is about 79 millimeters, and under the identical situation of fluorescent tube length, its light-emitting area is 168% of round lamp tube approximately.
The ratio of elliptical lamps pipe range axle and minor axis is big more, and luminous efficiency is high more, and energy-saving effect is remarkable more.The ratio of elliptical lamps pipe range axle and minor axis is generally greater than 1.2: 1.
The utility model can be used in the lamp of all kinds of light-emitting phosphors such as conventional fluorescent lamps, power saving fluorescent lamp, neon light and gaseous discharge lamp.
Claims (2)
1, a kind of oval fluorescent tube, the cross section that it is characterized in that fluorescent tube is for oval.
2, oval fluorescent tube according to claim 1, the ratio of major axis and minor axis of cross section that it is characterized in that oval fluorescent tube was greater than 1.2: 1.
