Novel quartz metal halide lamp

Abstract

The invention discloses a novel quartz metal halide lamp, which comprises an arc tube, a nickel sleeve, a ceramic tube, a bracket, a first molybdenum piece component, a second molybdenum piece component, a getter piece, a quartz tube and a lamp cap, wherein the nickel sleeve is sleeved at one end of an arc; the ceramic tube is sleeved on the bracket; the nickel sleeve is in spot welding connection with one end of the bracket; the other end of the bracket is in spot welding connection with the first molybdenum piece component; the bracket is in spot welding connection with the getter piece; the other end of the arc tube is in spot welding connection with the second molybdenum piece component; the first molybdenum piece component and the second molybdenum piece component are sealed in a base of the quartz tube through glass; and the first molybdenum piece component and the second molybdenum piece component are fixed on the lamp cap. The invention has the characteristics that the novel quartz metal halide lamp is reasonable in structure, and working environment temperature and tube wall load are reduced so that the novel quartz metal halide lamp is long in life; and the aim of high lumen maintenance is fulfilled.

Description

technical field [0001] The invention relates to a novel quartz metal halide lamp. Background technique [0002] Ordinary G12 quartz metal halide lamps are packaged on the outside of the arc tube with a quartz sleeve, which is generally produced with a smaller diameter quartz sleeve due to the size of the lamp cap. However, due to the small diameter of the quartz sleeve, the inner metal bracket and The arc tube is too close, which causes the metal halide inside the arc tube to penetrate to the outside of the arc tube, shortening the life of the lamp and drifting the color. At the same time, due to the small diameter of the quartz sleeve, the outer space for the arc tube to work becomes smaller, and the temperature of the working environment becomes higher, so that the light decay of the lamp is large, and the service life is shortened. Contents of the invention [0003] The object of the present invention is to provide a new type of quartz metal halide lamp. The invention...
