Technical field

The utility model relates to a kind of fluorescent tube, particularly a kind of energy-saving fluorescent lamp that reaches energy-saving effect by fluorescent tube moulding raising illuminance.

Background technology

The traditional fluorescent lamp tube structure as shown in Figure 1, 2, it mainly is made up of fluorescent tube 1, fluorescent tube flap 2, electrode 3 and fluorescent tube silk 4, fluorescent tube 1 two ends are provided with fluorescent tube flap 2, the fluorescent tube flap 2 of every end is provided with the pair of electrodes 3 with the insulation of fluorescent tube flap, be equipped with fluorescent tube silk 4 on the two end electrodes, be filled with the argon of trace and thin mercury vapour in the fluorescent tube, scribble fluorescent material on the tube inner wall, by putting on the voltage of two ends fluorescent tube silk electrode, make the interior gas ionization of pipe send ultraviolet ray, the fluorescent material on the inside pipe wall sends soft visible light under ultraviolet irradiation.Fluorescent lamp is compared with incandescent lamp, has luminous efficiency height (be common bulb 5 times), and is energy-conservation, the life-span long (be common bulb 8 times), low, the luminous advantage such as soft of thermal radiation and being widely used.Although existing fluorescent lamp has been obtained remarkable result aspect energy-conservation, those skilled in the art is still in continuous effort, and trying hard to has further breakthrough aspect energy-saving effect.As:

The patent No. 02216587.8 provides a kind of energy-saving fluorescent lamp of special construction, and it is made up of through bridge joint 2-5 U-shaped pipe, and two branched pipes of its each U-shaped pipe become the radian shape, and for example circular arc, ellipse arc etc. wholely become fluorescent tube cage type shape.Compare with straight pipe type U-shaped fluorescent tube, the distance between each branched pipe of this fluorescent tube increases, and helps improving heat dispersion, reduces light decay, improves light efficiency, and the general shape create an aesthetic feeling.This fluorescent tube is suitable for the illumination of various occasions such as family, office, meeting room to be used.

The patent No. 03268491.6 discloses a kind of energy-saving fluorescent lamp of obvious raising luminous efficiency, it is to connect bridge by at least three single lamp tube units to form, fluorescent tube be shaped as the flower shape, its outside is formed according to the petal shape arrangement combinations by at least two bandy lamp tube units of the radian by the certain curvature radius, and the centre is provided with a lamp tube unit at least; It is area source that this colored shape energy-saving fluorescent lamp has changed existing point-source of light, petal-shaped is formed by bandy lamp tube unit in the fluorescent tube outside, increased the gap between the adjacent lamps pipe unit, reduced the shading rate of interior sidelight, improved the heat dissipation environment of fluorescent tube simultaneously, reduce the temperature of fluorescent tube working region, so not only improved the luminous efficiency of fluorescent tube, and effectively prolonged the useful life of fluorescent tube.

Above-mentioned two patents strengthen illuminating area from the configuration of tube shape, reach energy-saving effect by improving lighting illumination intensity.

The patent No. 200620107562.7 provides a kind of energy-saving fluorescent lamp, and it comprises electrode, and stem stem, glass-tube and fluorescent tube head are filled with mercuryvapour and inert gas in the described glass-tube; The glass-tube inwall scribbles diaphragm and phosphor powder layer successively, and by being provided with reflecting coating in the corresponding arc double wall of central angle alpha, central angle alpha is 160 °-180 ° between particularly described diaphragm and the phosphor powder layer.Its lighting illumination intensity simple in structure, that can make fluorescent tube improves 30%.This patent improves lighting illumination intensity by reflecting coating and reaches energy-conservation purpose.

Still find no the energy-saving effect that improves fluorescent tube from the improved shape of fluorescent tube itself according to result for retrieval.The inventor continues research and development in line with excelsior creation spirit, and trying hard to has further breakthrough aspect energy-saving effect.According to being engaged in the theory and practice experience that light source design is made for a long time,, finding to can further improve the lighting illumination intensity of fluorescent tube finally, thereby create the utility model by the fluorescent tube moulding through constantly making great efforts innovation.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of energy-saving fluorescent lamp that can further improve energy-saving effect.

The cross sectional shape of existing fluorescent tube is circle, and from theory analysis as can be known, point-source of light institute is luminous to be as luminescence center, perpendicular to outwards launching with this direction as the sphere of the centre of sphere with point.Linear light source is as luminescence center, perpendicular to outwards launching as the direction of the sphere at the face of cylinder of axis and two ends with this straight line with the continuity point on the straight line.For the luminous element of linear pattern fluorescent tube, can regard linear light source as, the light of face of cylinder part vertical with surface of the light tube (as shown in Figure 3).If plane of illumination is parallel with fluorescent tube, then illumination on the plane of illumination and fluorescent tube distance is inversely proportional to.The luminous flux that is obtained on the plane of illumination is directly proportional with the ratio of tube circumference length to the fluorescent tube arc length (surface area) between two vertical lines of surface of the light tube with the plane of illumination both sides, and the fluorescent tube arc length between two vertical lines is long more, and the luminous flux that is obtained on the plane of illumination is big more.If change the cross sectional shape of fluorescent tube into ellipse (as shown in Figure 4), oval fluorescent tube the light of luminous face of cylinder part vertical with surface of the light tube, the angle between the elliptic arc two ends normal of the identical five equilibrium at ellipse short shaft two ends is less than the angle between the elliptic arc two ends normal of the identical five equilibrium at major axis two ends.Thereby, change the cross sectional shape of fluorescent tube into ellipse, the identical plane of illumination both sides of distance of the same area to the fluorescent tube arc length between two vertical lines of surface of the light tube than pipe fluorescent lamp pipe range, according to above analysis, oval fluorescent tube (luminous element) luminously have in the poly-effect that converges of short-axis direction.

Energy-saving fluorescent lamp provided by the utility model is realized by following technical scheme.

A kind of energy-saving fluorescent lamp comprises fluorescent tube, fluorescent tube flap, electrode and fluorescent tube silk, and the cross sectional shape that it is characterized in that described fluorescent tube is for oval, and electrode is located on the long axis of ellipse.
