Abstract
The utility model relates to a novel cold-cathode ultraviolet fluorescent lamp tube, which is composed of conducting wires, a cathode and an ultraviolet fluorescent lamp tube. The ultraviolet cold-cathode fluorescent lamp tube is characterized in that the lamp tube and the cathode are compounded by two layers of different materials of metal nickel and stainless steel; the outside of the compound metal sheet is also compounded with getter. The cathode by which the conducting wires are connected is sealed in the ultraviolet fluorescent lamp tube by tubes; the cathode can be made into the shape of a cylinder or a flat plate. The utility model takes the cold cathode to replace the technology that the existing hot cathode initiates fluorescent powder to shine, and thus, the ultraviolet fluorescent lamp can work under low temperature. The utility model has the characteristics of low energy consumption, high photoelectric conversion ratio and long service life. For reducing the volume of the lamp, the lamp tube can be made into a single spiral shape or a double spiral shape.
Description
The utility model relates to a kind of ultraviolet fluorescent lamp fluorescent tube, relates in particular to a kind of cold cathode ultraviolet fluorescent lamp fluorescent tube.
Fields such as the ultraviolet fluorescent lamp is widely used for sterilization, harmful, false proof, the amusement of going out.Existing ultraviolet fluorescent lamp is to adopt civil power is carried out after the unsteady flow filament in the fluorescent tube being heated, and produces the light-emitting phosphor in electron stream and the ultraviolet ray excited fluorescent tube.But,, this fluorescent tube produces long wave ultraviolet down so exciting at mercury line because the glass of fluorescent tube has been mixed with other compounds in the process of making, and adopts corresponding fluorescent material coated in tube wall.Existing ultraviolet fluorescent lamp fluorescent tube all needs filament (cathode) is heated when work, so there is very big a part of electric energy to be converted into heat energy, therefore the photoelectric conversion efficiency of ultraviolet fluorescent lamp is lower, and filament is at high temperature worked and is easy to fusing, because the photoelectric conversion rate of ultraviolet fluorescent lamp is also relevant with the caliber of ultraviolet fluorescent fluorescent tube, promptly detailed rules and regulations unit are photoelectric conversion rate is high more more for fluorescent tube.Existing ultraviolet fluorescent fluorescent tube needs that filament is made the arachnoid pipe and is enclosed in the fluorescent tube, thereby the caliber of fluorescent tube can't be done to such an extent that be less than or equal to 3 millimeters.And, produce early failure because the heat that heat filament produces makes the electronic component in the electric ballast with ultraviolet fluorescent lamp compatibility aging easily.
In order to improve the photoelectric conversion rate of ultraviolet fluorescent lamp, improve the useful life of fluorescent tube.The utility model aims to provide a kind of novel cold cathode ultraviolet fluorescent lamp fluorescent tube.It has higher photoelectric conversion efficiency, can make than tubule footpath, the useful life of improving electronic component and ultraviolet fluorescent lamp fluorescent tube.
The utility model is by lead 5, institutes such as negative electrode 6 and ultraviolet fluorescent fluorescent tube 7 form, it is characterized in that described cathode 6 is by the metallic nickel of two layers of unlike material and stainless steel is compound forms, and getter arranged again also outside this composite metal, lead 5 is connected with negative electrode 6, and is enclosed in the ultraviolet fluorescent lamp fluorescent tube 7 by pipe.
The utility model can be made straight light tube, in order to improve brightness, and reduced volume, the utility model can be made into nonlinear type, promptly makes helical type lamp.The related negative electrode of the utility model can be made into the garden tubular also can make tabular.
Fig. 1, Fig. 2 are the ultraviolet fluorescent lamp electricity-saving lamp sketches that utilizes the utility model made.1 is lamp holder among the figure, and 2 is lampshade, and 3 is the single-screw fluorescent tube, and 4 is the double helix quartz burner.In lamp holder 1, electronic circuit component is housed, make civil power convert about 50KC again to through rectification, be delivered to negative electrode by lead behind the 1500V voltage, inert gas and mercury vapour that negative electrode produces under the effect of voltage in the electron stream starter fluorescent tube cause light-emitting phosphor then.Lengthening fluorescent tube length, the brightness that can improve fluorescent tube so in order to reduce the volume of light fixture, fluorescent tube can be made Double-spiral as shown in Figure 1, also can be made into single-screw shape as shown in Figure 2.In order to protect fluorescent tube outside fluorescent tube, to refill lampshade 2.
In order to strengthen the weld strength of lead and negative electrode, negative electrode can be made tabular.
It is low to the utlity model has energy consumption, photoelectric conversion efficiency height, the characteristics of long service life.
Description of drawings is as follows:
The double helix fluorescent tube electricity-saving lamp of Fig. 1 for adopting the utility model to make, wherein 1 is that lamp holder, 2 is lampshade, 4 is the double helix fluorescent tube.
The single-screw fluorescent tube electricity-saving lamp of Fig. 2 for adopting the utility model to make, wherein 1 is lamp holder, and 2 is lampshade, and 3 is the single-screw fluorescent tube.
Fig. 3 is a cutaway view of the present utility model.Wherein 5 is lead, and 6 is negative electrode, and 7 is fluorescent lamp tube.
Fig. 4 is the related cathode construction sketch of the utility model.Wherein 8,9, be two different metals sheets, 10 for covering the getter outside the sheet metal.
