[0007] The protective net is formed by spirally winding explosion-proof metal wire.

[0008] The explosion-proof tube is made of quartz or glass.

[0009] The wall thickness of the explosion-proof tube is 1.5-3 mm.

[0010] Compared with the prior art, this explosion-proof ceramic metal halide lamp has the following advantages:

[0011] In the utility model, an elastic positioning piece is added, so that the long bracket can be fixed more reliably. The explosion-proof tube is connected to the long bracket through a positioning ring, and a protective net formed by spirally winding an explosion-proof metal wire is also arranged on the outside, which plays a secondary protection role and also plays an auxiliary reinforcement role in the connection between the explosion-proof tube, the positioning ring and the long bracket.
