[0027] The water cooling assembly 3 comprises a water cooling plate 31, a sealing ring 32, a sealing cover 33, a water inlet connector 34 and a water outlet connector 35. The water cooling plate 31 is internally provided with two water cooling channels 311. Threaded grooves 310 are arranged on the two end faces of the water cooling plate 31. The sealing covers 33 are mounted on the two sides of the water cooling plate 31. Screws pass through the sealing covers 33 and are locked to the threaded grooves 310, so that the sealing covers 33 are sealingly mounted to the water cooling plate 31. The sealing covers 33 are fixed to the inner wall of the lamp shell 1. The water cooling plate 31 and the sealing covers 33 are sealed by the sealing ring 32. The sealing ring 32 is arranged on the periphery of the water cooling channels 311 to prevent leakage of the cooling liquid. The water inlet connector 34 for water inlet and the water outlet connector 35 for water outlet are mounted on one of the sealing covers 33.
