Abstract
The utility model relates to an energy-saving fluorescent lamp tube comprising an electrode, a stem, a glass tube and a lamp cap, wherein, the glass tube is filled with mercury vapor and inert gas; the inner wall of the glass tube is sequentially coated with a protective layer and a fluorescent powder layer, and in particular between the protective lay and the fluorescent powder layer is arranged a reflection layer on an arc wall cavity opposite to a central angle alpha of 160 degrees-180 degrees. The utility model can increase the illumination intensity of the fluorescent lamp tube by 30 percent with simple structure.
Description
Technical field
The utility model relates to a kind of fluorescent tube, particularly a kind of energy-saving fluorescent lamp.
Background technology
Traditional fluorescent lamp tube, the light that the reflective surface of common employing lampshade sends fluorescent tube dorsad when practical application is reflected into forward light, to improve the brightness of illumination of fluorescent tube.But since service time permanent after, the face dorsad of fluorescent tube and the reflective surface of lampshade all are exposed in the air, constantly dust is gone up in accumulation, make the forward light that can reflect more and more a little less than, even lose the function and the effect of reflective enhancing illumination.
Summary of the invention
The utility model provides a kind of improved energy-saving fluorescent lamp, to solve the problem that above-mentioned fluorescent tube reflect lighting exists.
A kind of energy-saving fluorescent lamp described in the utility model comprises electrode, and stem stem, glass-tube and lamp holder are filled with mercuryvapour and inert gas in the described glass-tube; The glass-tube inwall all scribbles protective film and phosphor powder layer, it is characterized in that: by being provided with reflexed light film in the corresponding arc double wall of central angle alpha, central angle alpha is 160--180 ° between described protective film and the phosphor powder layer
The utility model is owing to be provided with reflexed light film by central angle alpha in the corresponding arc double wall between protective film and phosphor powder layer; when the ultraviolet ray excited fluorescent material that produces when mercury gas discharge and the light that sends are mapped to reflexed light film dorsad; its light will be reflected into forward light by reflexed light film; its lighting illumination intensity simple in structure, that can make fluorescent tube improves 30%, and can avoid the dust influence.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be among Fig. 1 A-A to the cross section structure enlarged diagram.
Embodiment
As Fig. 1, shown in Figure 2, a kind of energy-saving fluorescent lamp comprises glass-tube 1, electrode 2, and stem stem 4, lamp holder 4 are filled with mercuryvapour and inert gas in the described glass-tube 1; The inwall of glass-tube 1 all scribbles protective film 11 and phosphor powder layer 13, also is provided with special reflexed light film 12 in the part by the corresponding arc double wall of central angle alpha between described protective film 11 and the phosphor powder layer 13, and central angle alpha is 160--180 °.
In glass-tube 1, protective film 11 directly is coated on the inwall of glass-tube 1; Arc wall part by 180 ° of central angle alpha correspondences applies reflexed light film 12 on protective film 11 then; The last phosphor powder layer 13 that on their inwall, applies.Described central angle alpha also can be made as 160 °.
The protective film 11 that described glass-tube 1 inwall is provided with, phosphor powder layer 13 and 12 3 kinds of coatings of reflexed light film are arranged in order from outside to inside, and reflexed light film 12 is sandwiched in the middle of protective film 11 and the phosphor powder layer 13, as shown in Figure 2.
During application, the part that fluorescent tube is provided with reflexed light film is as the back, the ultraviolet ray excited fluorescent material that produces by mercury gas discharge in the fluorescent tube and the light that sends, and when the fluorescent tube back injects to reflexed light film, its light will be reflected into forward light by reflexed light film.It is simple in structure, and the lighting illumination intensity of fluorescent tube improves 30%, has remarkable energy saving effect.
