Quartz metal halide lamp

Abstract

The invention discloses a quartz metal halide lamp which comprises an electric arc pipe, a nickel casing pipe, a ceramic pipe, a support, a first molybdenum piece component, a second molybdenum piece component, an electrolytic gettering sheet and a quartz tube, wherein the nickel casing pipe is sheathed at one end of the electric arc pipe, the ceramic pipe is sheathed on the support, and the nickel casing pipe is in spot welding connection with one end of the support; the other end of the support is in spot welding connection with the first molybdenum piece component; the electrolytic gettering sheet is in spot welding connection on the support; the other end of the electric arc pipe is in spot welding connection with the second molybdenum piece component; the first molybdenum piece component and the second molybdenum piece component are packaged in a base of the quartz pipe through glass. The quartz metal halide lamp has the characteristics of reasonable structure, reduced working environment temperature and decreased pipe wall load, thereby the purposes of long service life and high lumen maintenance are achieved.

Description

technical field [0001] The invention relates to a quartz metal halide lamp. Background technique [0002] Ordinary G8.5 quartz metal halide lamps are packaged with quartz sleeves outside the arc tube. Due to the size of the lamp holder, they are generally produced with smaller diameter quartz sleeves. However, due to the small diameter of the quartz sleeves, the inner The metal bracket is too close to the arc tube, 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 causing color drift. 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 quartz metal halide lamp. The invention has the characteris...
