专利汇可以提供Metal halide lamp专利检索,专利查询,专利分析的服务。并且PURPOSE: To improve color display property and luminescence efficiency of a lamp of short electrode distance and high tube wall load by determining the quantity of close rare earth metal, the weight ratio between the alkali metal and the rate earth metal and the quantity of close Br within respective specific ranges.
CONSTITUTION: In a luminous tube (t) having an electrode gap of less than 2cm between electrodes 2 and 3 and a tube wall load of between 20W120W/sq.cm, the close quantity of rare earth metal is 0.4W5.0mg/cc, the weight ratio of alkali metal to the rare earth metal is 0.1W0.8, and the ratio of excessive close quantity of Br to the rare earth metal is 0.01W0.09mg/cc. For example, Hg, Ar gas, bromides of Dy, Ho, Tm and Hg are closed in a quartz luminous tube having a electrode gap of 10mm, a tube wall load of 42W/sq.cm and inside diameter of 10mm satisfying the conditions hereinbefore described, thus improving the luminescence efficiency and luminous flux maintenance and stabilizing the arc.
