The invention proposes an explosion-proof single-ended ceramic metal halide lamp, and the lamp comprises a glass housing, a lamp cap disposed at one end of the glass housing, a U-shaped metal frame disposed in the glass housing, a wick column disposed in the lamp cap, and a light source disposed in the U-shaped metal frame. The U-shaped metal frame comprises two parallel metal vertical rods and ametal cross rod which is connected with the two metal vertical rods. The wick column is disposed at the opening end of the U-shaped metal frame, and is connected with the two metal vertical rods. Theouter side of the light source is sleeved by an explosion-proof quartz tube, and the metal vertical rods are fixedly connected with a positioning circular ring which sleeves the explosion-proof quartztube. According to the invention, the U-shaped metal frame and the positioning circular ring enable the explosion-proof quartz tube to be installed between the glass housing and the light source. Thelamp is good in explosion-proof performance, is stable and firm in structure due to the setting of a fixing piece and a V-shaped elastic piece, is compact and light, is good in safety, and meets therequirements of various application occasions.
Description
technical field [0001] The invention relates to the field of electrical technology, in particular to an explosion-proof single-ended ceramic metal halide lamp. Background technique [0002] Ceramic metal halide lamp is a kind of gas discharge lamp. It is a new light source developed on the basis of quartz metal halide lamp and high pressure sodium lamp manufacturing technology. It has long life, high luminous efficiency, good color rendering, stable light color, etc. Advantages, widely used in stadiums, shopping malls, roads, factories, squares, urban landscapes, airports, stations, ports, plant cultivation and other fields. At present, most of the existing high-power single-ended ceramic metal halide lamps do not have explosion-proof functions, and can only be used in airtight lamps, which is inconvenient to use and install, and the cost is high. Contents of the invention [0003] In order to solve the above problems, the present invention proposes an explosion-proof sin...
