Abstract
The utility model relates to a lighting lamp, in particular to a multiple U-shaped compound cathode gas discharge lamp with cold end, which is characterized in that based on original U-shaped discharge tube structure, the lamp comprises a plurality of U-shaped lamps; each unit U-shaped lamp is communicated with each other by a glass tube; one to two ends are arranged near the hot cathode end of each U-shaped lamp; the cold end is connected with the intracavity of the lamp, and deviated from the discharge channel of the discharge tube; one group or more than one group of cold cathode and hot cathode are connected in parallel at the place of the hot cathode, which are combined into a compound cathode; the cold end is an L-shaped glass tube or a straight pipe shape glass tube; the compound cathode is integrated style or split style; a linear line or shaped opening is made at the center of the compound cathode; the cold end structure can be dual-way or unidirectional structure, and is connected with the lamp by inner and external cavity structure having the same or different shape with lamp. The lighting lamp has the advantages of low starting voltage, significant increasing of illumination intensity and no mercury pollution, which can used as plane light source or plane radiation source, and the general irradiating surface can be increased by n times.
Description
Technical field
The utility model relates to lighting, particularly a kind of many U-shapeds of band cold junction composite cathode discharge tube.
Background technology
Low mercury is in the past pressed high-power gas charging lamp, as is contained in the sealed lamps case, and along with the rapid rising of temperature, the ultraviolet spectral line can produce serious skew, influences the useful life and the light efficiency of light fixture.If improved, two-way or unidirectional cold end structure has been arranged, can artificially set the length of cold end structure, the temperature that shape is regulated cold junction in conjunction with pilulae hydrargyri technology, and then the mercury vapour of control discharge tube is pressed and the suitable spectral line of selection mercury, just can significantly improve the luminous efficiency of discharge tube.
The utility model content
The purpose of this utility model is at above-mentioned defective, and a kind of many U-shapeds of band cold junction composite cathode gas discharge tube is provided.
The technical solution of the utility model is a kind of many U-shapeds of band cold junction composite cathode gas discharge tube, comprise the U-shaped fluorescent tube, coated has fluorescent material in the fluorescent tube, at the socket place of fluorescent tube filament is installed and connects and constitute hot cathode with electrode, it is characterized in that said fluorescent tube is to be combined by several U-shaped fluorescent tubes, have glass-tube to be communicated with between each unit U-shaped fluorescent tube; Also be provided with one to two cold junction near the hot cathode end of every U-shaped fluorescent tube, this cold junction not only is connected in tube cavity but also deviate from discharge channel; A group or more cold cathode and hot cathode in parallel formed composite cathode at the hot cathode place.
Said cold junction is L shaped glass-tube or straight tube shape glass-tube; Said composite cathode is an integral type or split type, straight line middle opening on it; Said cold end structure can be bi-directional configuration or check configuration, adopt with the fluorescent tube similar shape or not the interior outer-cavity structure of similar shape be connected with fluorescent tube.
The utility model has the advantages that 1, composite cathode adopts new material and new shape structure, can reduce the starting voltage of discharge tube, quickens the effusion of mercury atom, improves the life-span of gas discharge tube; 2, adopt inside pipe wall to be coated with the U-shaped of band cold junction of fluorescent material or the high-power low mercury pressure gas discharge pipe of many U-shapeds structure, can significantly improve luminous efficiency, draw light efficiency from analysis of experimental data and can improve 15%-25%; 3, the high-power low pressure gaseous discharge inside pipe wall of this U-shaped and many U-shapeds structure is coated rare-earth trichromatic fluorescent powder, can improve the flat illumination of large tracts of land working face, improves the illumination of working face, reaches significantly energy-conservation effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the another kind of structural representation of composite cathode.
Embodiment
Further specify embodiment below in conjunction with accompanying drawing.
With reference to Fig. 1, Fig. 2,1-U shape fluorescent tube, 2-hot cathode, 3-cold junction, 4-cold cathode, 5-glass-tube, 6-electrode seal wire.As shown, original discharge tube comprises U-shaped fluorescent tube 1, hot cathode 2, and coated has fluorescent material in the fluorescent tube, at the socket place of fluorescent tube filament is installed and connects with electrode.Innovation part of the present utility model is to be provided with one to two cold junction 3 near the hot cathode end of fluorescent tube 1 by several U-shaped fluorescent tubes, 2 in the outside, 2 of inboards among the figure, three U-shaped fluorescent tubes.Cold junction 3 not only is connected in tube cavity but also deviate from discharge channel.A group or more cold cathode and hot cathode in parallel formed composite cathode at hot cathode 2 places.Composite cathode can be set to integral type or split type, straight line middle opening or make on it
Shape, what present among the figure is split type.In addition, cold end structure can be bi-directional configuration or check configuration, adopts with fluorescent tube to be connected with fluorescent tube with shape or difform interior outer-cavity structure.Composite cathode can be used common non-ferrous metal, and also available multiple compound rare precious metal material is made.Only three the unit U-shaped glass-tubes that show among the figure combine, and can adopt many U-shapeds, and the length of discharge tube is not limit, as long as can discharge.Cold end structure can adopt the same type of material with discharge tube, also can adopt foreign peoples's material, also can be designed to multiple profile and various special-shaped inner chamber according to cold end structure.Discharge tube is owing to many U-shapeds of employing structure, and the raising light efficiency, therefore can improve the flat illumination of large tracts of land working face, improves the illumination of working face, thereby reaches remarkable energy-conservation effect.
