Abstract
The utility model discloses a compact high power fluorescent lamp tube with a connection type cold end. The connection type cold end is formed by a glass tube with a small tube diameter, and is carried through directly butt-joint with the position range of the top part of the fluorescent lamp in a hot-working mode, the cold end is communicated with the lamp tube, and the cold end and the lamp tube are combined into as an integral body. Since the utility model adopts the connection type cold end that is arranged independently, the cold end of the fluorescent lamp tube can be arranged at the optimum temperature and the optimum position. Therefore, the mercury gas-pressure of the high power fluorescent lamp tube is adjusted to be in the optimal value state, and is influenced little by temperature changes. The compact high power fluorescent tube with the connection type cold end can be applied to the illumination field.
Description
Technical field
The utility model relates to a kind of fluorescent tube, especially relates to a kind of cold junction setting of compact type large power fluorescent tube.
Background technology
Compact fluorescent lamp is since the eighties in 20th century invention, because its light efficiency height, life-span length, compact conformation, characteristics such as energy-conservation have been widelyd popularize, becomes the main light source of room lighting.But the power of conventional compact fluorescent lamp is less, and the lumen output of single lamp is lower, and this has just limited it in the wider application of lighting field.In order to enlarge range of application, with the compact fluorescent lamp high-power, the lumen output of single lamp is improved, to satisfy the requirement of practical application, its prospect is very tempting.But the power of compact fluorescent lamp increases substantially, lamp current density is risen, thereby electron density is risen, cause the pipe temperature to rise, the mercury vapour in the fluorescent tube is pressed the optimal values that has departed from cold junction, makes lamp power and lumen that obvious decline all be arranged, especially in totally enclosed lampshade, work, its lamp power and lumen descend severely more, reach more than 20%, thereby have influenced applying of compact type large power fluorescent tube.
The utility model content
The purpose of this utility model is to provide a kind of compact type large power fluorescent tube with interconnection system cold junction.
The purpose of this utility model can realize by following technical measures: at the compact type large power fluorescent tube, tip position scope as the high-power fluorescent tube of spiral type, adopt the mode of hot working butt joint, with the connection that is melt through of an end of the glass tube of a little caliber, the other end adopts the hot working sintering, is provided with an interconnection system cold junction so artificially.Constituting the diameter of the tubule footpath glass tube of interconnection system cold junction, the length of length of tube, is that shape and the power according to the compact type large power fluorescent tube decides.The utility model compared with prior art has the following advantages: because the important electrical quantitys such as operating voltage (light tube electric voltage) luminous efficiency of fluorescent lamp, all press in close relations with the interior mercury vapour of pipe, and the occurrence that mercury vapour is pressed in the pipe, the temperature that depends on fluorescent tube inner glass tube temperature lowest part (being commonly called as cold junction), therefore, the temperature of control cold junction has just equaled to control the mercury vapour pressure in the fluorescent tube.For the compact type large power fluorescent tube, often mercury vapour is pressed too high and light efficiency is significantly descended, the setting of the fluorescent tube cold junction of current technology, just optionally at the top or the filament position be provided with, thereby cause lamp power and lumen temperature influence and the bad phenomenon that descends, and be provided with a cold junction artificially, difformity and different capacity according to the compact type large power fluorescent lamp, the glass tube of cold junction adopts the design of different tube diameters and different length, make the cold-end glass in the fluorescent tube be controlled at best state of temperature, thereby the mercury vapour of having controlled in the fluorescent tube is pressed, to reach best operating state, and can be acted upon by temperature changes, guaranteed the consistency of lamp power and light efficiency effectively, to satisfy the requirement of practical application. lessly
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is the structural representation of the spiral type large power fluorescent lamp tube of band interconnection system cold junction.
Fig. 2 is the structural representation of four U type large power fluorescent lamp tubes of band interconnection system cold junction.
Fig. 3 is for adopting the interconnection system cold end structure schematic diagram of gluing connection.
Fig. 4 is the interconnection system cold end structure schematic diagram that adopts the glass tube of other shape.
Embodiment
As shown in Figure 1, one end of the glass tube of little caliber is carried out hot working tack 5 to be handled, then the other end is placed on tip position 2 scopes of spiral type large power fluorescent lamp tube 1, utilize the disjunctor behind the glass melting to connect after adopting flame to punch with the glass tube fusing and fluorescent tube 1 coupling part, should lead to gas during connection and guarantee that fluorescent tube 1 is unimpeded with the glass tube connecting portion 4 of cold junction 3, after the cooling, constitute the spiral type large power fluorescent lamp tube of band interconnection system cold junction.Because the important photoelectric parameters such as operating voltage (light tube electric voltage) luminous efficiency of fluorescent lamp, all press in close relations with the interior mercury vapour of pipe, and the optimum value that mercury vapour is pressed in the pipe, the temperature that depends on the glass tube temperature lowest part (being commonly called as cold junction) in the fluorescent tube, thereby controlled the temperature of cold junction, the mercury vapour that has just equaled to control in the fluorescent tube is pressed, and the glass tube of interconnection system cold junction not only is placed on the tip position scope of fluorescent tube, and be the centre position that is placed on fluorescent tube, like this, no matter be the variation of ambient temperature that fluorescent tube self temperature or fluorescent tube use, variation to cold junction temperature is little relatively, thereby guaranteed the temperature of cold junction, also guaranteed the optimum value that the mercury vapour in the fluorescent tube is pressed.Thereby solved owing to cold junction temperature changes the existing problems that the lamp power cause and lumen descend.
Fig. 2 is the structural representation of large power fluorescent lamp tube interconnection system cold junctions such as 4U, 6U, 8U, and its connected mode is the same with Fig. 1.
Fig. 3 is the interconnection system cold end structure schematic diagram that the method for the gluing connection of employing is carried out.As shown in the figure, earlier fluorescent tube tip position scope is used power auger one hole, adopt the tapered wheel polishing that certain taper is arranged, equally, external diameter at tubule footpath glass tube can also adopt grinder buffing that certain tapering is arranged, be stained with glass high-temp glue 6 then, glass tube 3 and fluorescent tube 1 carried out bonding, promptly become the fluorescent tube of band interconnection system cold junction behind the hyperthermia drying.
Fig. 4 is the interconnection system cold end structure schematic diagram that adopts the glass tube of other shape.
Can be operated in the optimum temperature state in order to ensure cold junction and constitute the caliber size of tubule footpath glass tube of cold junction and the length of pipe, determine according to the fluorescent tube of difformity and different capacity.Produce the phenomenon of ultraviolet light simultaneously when working for fear of the glass tube of interconnection system cold junction, this glass tube can also be coated fluorescent material and dry the back use.
