Abstract:
     General tube of halogen tungsten lamp can'nt be directly used as underwater light which directly contacts with water or used for places with low ambient-temp. and good heat-conductive condition, or air conditioned places using local-exhausting or water-cooling to cool tube for reducing refrigeration duty, because the tungsten halogen regeneration is ensured only when its tube-wall temp. is up to 250-700 degree C. This invention adopts double glass-casing structure to reduce heat-conducting loss and ensure the temp. of tube-wall up to the temp. required for tungsten halogen regeneration. Advantage: simple process, low cost and easy for application .
