Novel energy saving double-end iodine-tungsten lamp

Abstract

The invention relates to a lamp, in particular to a novel energy saving double-end iodine-tungsten lamp. The novel energy saving double-end iodine-tungsten lamp comprises a lamp holder, a lamp tube, a lamp filament and molybdenum plate assemblies, wherein the molybdenum plate assemblies are arranged at the two ends of the lamp tube; the lamp filament comprises two light emitting bodies, a connecting body and filament tails, the connecting body is arranged between the two light emitting bodies, the filament tails are arranged at the two ends of the lamp filament, a dented pit is arranged in the middle of the connecting body, and the projecting part of the pit is in contact with the lamp tube. The whole lamp filament is supported and prevented from sagging through the arrangement of the pit in the middle of the joint of the lamp filament and the contact arrangement of the projecting part of the dented pit and the lamp tube, and holder rings are not arranged; besides, as the whole lamp filament is molded once, the whole procedure of winding the holder rings is saved, the holder rings do not need to be burned concave one by one, the purposes of energy saving and environment protecting are achieved, and the production efficiency can be improved. The novel energy saving double-end iodine-tungsten lamp has the advantages of skillful structure, energy saving, environment friendliness, high brightness, long service life, simple technology and the like.

Description

technical field [0001] The invention relates to a lamp, in particular to a novel energy-saving double-ended iodine-tungsten lamp. Background technique [0002] Compared with ordinary incandescent lamps, iodine-tungsten lamps can greatly reduce the evaporation of tungsten, prolong the service life, and improve the working temperature and luminous efficiency. Iodine-tungsten lamps have a service life twice as long as ordinary incandescent lamps, and their luminous efficiency is about 30% higher than that of ordinary incandescent lamps. At present, the common double-ended iodine-tungsten lamps for lighting on the market include lamp tubes, molybdenum sheet components at both ends of the lamp tubes, and filaments. Common iodine-tungsten lamp filaments are composed of a whole helical tungsten wire. The distance between the helical coils of this structure is tight, and the heat energy utilization rate is low when the heat is emitted, the brightness is not high, and the heat is no...

AI Technical Summary

Problems solved by technology

Common iodine-tungsten lamp filaments are composed of a whole helical tungsten wire. The distance between the helical coils of this structure is tight, and the heat energy utilization rate is low when the heat is emitted, the brightness is not high, and the heat is not easy to dissipate; another On the one hand, in order to prevent the entire filament from touching the inner wall of the lamp tube due to sagging during use, it is necessary to use a tungsten wire support ring as a bracket to support the filament at a certain distance on the filament, and the number of bracket rings is large, which not only wastes materials , and bring inconvenience to production and processing, affecting production efficiency
