Abstract

The invention discloses a quartz metal halogen lamp which comprises a discharge container, wherein a heat resistant material layer is coated on the tube wall of an inner cavity body of the discharge container of the quartz metal halogen lamp; the heat resistant material layer is made from aluminum oxide nanometer, and the particle size of the aluminum oxide nanometer is 1-100nm. By coating the heat resistant material layer on the tube wall of the inner cavity body of the discharge container of the quartz metal halogen lamp, the quartz metal halogen lamp solves the technical problems of poor luminescence property and shortened service life of the metal halogen lamp, resulting from the fact that the tube wall material of the cavity body of the traditional quartz metal halogen lamp discharge tube adopts a quartz tube and scandium or other rare earth and a quartz tube shell react to form silicate and halide of silicon under a high-temperature work state.

Description

technical field [0001] The invention relates to a lamp, in particular to a quartz metal halide lamp, which belongs to the technical field of electric light sources. Background technique [0002] Metal halide lamps are currently one of the mainstream energy-saving electric light sources. They have the characteristics of high luminous efficiency, good light color, wide application range, long life, compact structure, and stable performance. They have been widely used in cities, roads, and ports. , Stations, docks, airports, stadiums, factories, mines, theaters, commercial, forestry, buildings and other indoor and outdoor lighting fields. [0003] Metal halide lamps are mainly divided into two series: ceramic metal halide lamps and quartz metal halide lamps: [0004] Ceramic metal halide lamps are developed on the basis of high-pressure sodium lamps and quartz metal halide lamps. Polycrystalline alumina translucent ceramics are used as arc tube materials. , currently only a f...
