Abstract
The utility model brings forward a straight tube type fluorescent lamp comprising lamp holders and a lamp tube. Lamp bases and lamp filaments are respectively arranged at the lamp holders, wherein the two lamp holders are arranged in parallel. The lamp tube is installed between the two lamp holders; the two lamp filaments are respectively arranged in the lamp tube; the inner wall of the lamp tube is coated by fluorescent powders; and the inside of the lamp tube is filled with argon and mercury. A mirror surface area is arranged at the side4 wall of the lamp tube, wherein the moving direction of the mirror surface area is identical with the length direction of the lamp tube; and the inner wall surface, except the mirror surface area, of the lamp tube is coated by the fluorescent powders; and the outer wall surface, in the mirror surface area, of the lamp tube is coated by a mirror surface reflection coating layer. When the straight tube type fluorescent lamp is used, the mirror surface reflection coating layer at the outer wall of the lamp tube reflects ultraviolet rays and the fluorescent powders emit visible lights, thereby improving the luminous efficiency of the fluorescent lamp; and the using amount of the mercury material is reduced, thereby achieving an objective of the environment protection.
Description
Technical field
The utility model relates to a kind of straight pipe type fluorescent lamp.
Background technology
At present, straight pipe type fluorescent lamp generally is applied in the every aspect of our life, its structure is respectively arranged with lamp base and filament for comprising on lamp holder, two parallel placements of lamp holder, and the fluorescent tube of circular tube shaped is installed between two lamp holders, tube inner wall scribbles fluorescent material, be filled with the argon gas of 400Pa-500Pa pressure and a small amount of mercury in pipe, lamp tube ends is respectively arranged with filament, under the alternating voltage effect, filament is alternately as negative pole and positive pole, after energising, liquid mercury flashes to the mercury vapour that pressure is 0.8Pa, under electric field action, mercury atom constantly is provoked into excitation state from reset condition, then spontaneous transition is to ground state, and give off the ultraviolet ray of wavelength 253.7nm and 185nm, to discharge unnecessary energy, fluorescent material sends visible ray after absorbing ultraviolet radiant energy, the electric energy major part consumed due to fluorescent lamp is for generation of ultraviolet ray, therefore, the luminous efficiency of fluorescent lamp is high more than incandescent lamp and tungsten halogen lamp.
But present used straight pipe type fluorescent lamp has luminous efficiency low, inner mercury material excessive use makes old and useless fluorescent lamp harm environment, environmental protection etc. not.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of minimizing power consumption, improves luminous efficiency, reduces the straight pipe type fluorescent lamp of mercury material usage.
For solving the problems of the technologies described above, the utility model provides a kind of straight pipe type fluorescent lamp, comprise lamp holder and fluorescent tube, be respectively arranged with lamp base and filament on lamp holder, two parallel placements of lamp holder, between two lamp holders, fluorescent tube is installed, two filaments are separately positioned in fluorescent tube, tube inner wall scribbles fluorescent material, be filled with argon gas and mercury in fluorescent tube, described fluorescent tube sidewall has mirror sections, the trend of mirror sections is consistent with the length of fluorescent tube trend, described fluorescent material is coated in the tube inner wall surface except mirror sections, tube outer wall surface in mirror sections scribbles mirror face reflection coating.
After adopting such structure, during straight pipe type fluorescent lamp work, mirror face reflection coating uv reflectance and the fluorescent material of tube outer wall send visible ray, improve the luminous efficiency of fluorescent lamp, and reduce the consumption of mercury material, reach the purpose of environmental protection.
In order to be easier to understand technology contents of the present utility model, below by the utility model straight pipe type fluorescent lamp referred to as this fluorescent lamp.
In the mirror sections of fluorescent tube sidewall between two filaments of this fluorescent lamp, the groove be recessed to form is arranged, the trend of groove is consistent with the length of fluorescent tube trend.
After adopting such structure, can increase the radiation area of mirror face reflection coating, further improve the luminous efficiency of this fluorescent lamp.
The cross sectional shape of the groove of this fluorescent lamp is arc; After adopting such structure, groove is arc, makes this fluorescent lighting best results.
The mirror face reflection coating of this fluorescent lamp adopts silver-plated or aluminum plating process; After adopting such structure, silver-plated and aluminize and make the reflecting effect of mirror face reflection coating best, and also technique is simple, facilitates industrial processes.
The accompanying drawing explanation
Fig. 1 is the front view of this fluorescent lamp embodiment.
Fig. 2 is the amplification view of Fig. 1 along the A-A direction.
Fig. 3 is the enlarged drawing of M part in Fig. 2.
Embodiment
As shown in Figures 1 to 3, be respectively arranged with lamp base 3 and filament 2 on lamp holder 1, two parallel placements of lamp holder 1, and two filaments 2 are relative, the fluorescent tube 4 of glass material is installed between two lamp holders 1, fluorescent tube 4 side wall upper part have mirror sections, the length direction of mirror sections is consistent with the length direction of fluorescent tube 4, between two filaments 2 of correspondence, the first groove 7 that on fluorescent tube 4 tube walls, the minute surface area depression forms is arranged, the cross sectional shape of the first groove 7 is circular arc, fluorescent tube 4 outer wall surface are by the silver-plated or formation one deck mirror face reflection coating 6 of aluminum plating process in mirror sections, fluorescent tube 4 inner wall surface outside mirror sections scribble fluorescent material, form fluorescent coating 5, two lamp holders and the interior sealing of fluorescent tube 4, be filled with argon gas and a small amount of mercury in fluorescent tube 4.
During use, lamp base 3 and the power supply of straight tube fluorescent lamp join, under the alternating voltage effect, filament 2 is alternately as negative pole and positive pole, after energising, liquid mercury flashes to mercury vapour, under electric field action, mercury atom constantly is provoked into excitation state from reset condition, then spontaneous transition is to ground state, and give off ultraviolet ray, to discharge unnecessary energy, fluorescent material sends visible ray after absorbing ultraviolet radiant energy, visible ray is through the reflection of mirror face reflection coating 6, promote the illuminating effect of this fluorescent lamp, improve the luminous efficiency of fluorescent lamp, and the consumption of minimizing mercury material, reach the purpose of environmental protection.
Above-described is only a kind of execution mode of the present utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model principle; can also make some modification and improvement; these also should be considered as belonging to protection range of the present utility model, such as the cross sectional shape of the first groove is square, trapezoidal, multiple changing type etc.
