High-power metal halide lamp tank tube

The utility model discloses a high-power metal halide lamp tank tube, comprising a tank tube body and lamp caps, wherein positive and negative lamp caps are arranged at two ends of the tank tube body; a bracket is arranged in the tank tube body; two ends of the bracket are respectively inserted into fixed shell covers and are fixedly connected with the lamp caps; upper, middle and lower metal halide lamp tank tube bodies are also arranged in the tank tube body; a tungsten filament is arranged in each metal halide lamp tank tube body; two ends of each metal halide lamp tank tube body are externally connected with molybdenum rods; each tungsten filament is fixedly connected with one end of each molybdenum rod through each shell cover; the shell covers are connected with each other and are connected with the bracket through clamping strips; negative molybdenum rods of the metal halide lamp tank tube bodies are connected with each other and are connected with the negative lamp cap; positive molybdenum rods of the metal halide lamp tank tube bodies are connected with each other and are connected with the positive lamp cap; and resistors are arranged on the positive molybdenum rods. According to the high-power metal halide lamp tank tube, the problem of contradiction between the service life and high power of a single lamp tube is overcome; the long service life and the high power brightness can be achieved at present; and the overall metal halide lamp plays a relatively great role by adopting the combination of a plurality of lamp bodies.
