The invention has the beneficial effects that: the lamp holder realizes the pitching of the lamp on the lamp holder by +/-45 degrees and the rotation of the lamp on the lamp holder by +/-45 degrees through simple structural design and reliable connection. The lamp holder is connected with the sliding block embedded in the aluminum alloy frame beam, so that the lamp can horizontally move on the beam, and can be stopped and fixed at a specified position by locking the screw. The longitudinal position of the lamp can be moved by moving the cross beam in the aluminum alloy frame of the lamp array up and down between the longitudinal beams of the frame, and the lamp can be stopped and fixed at a specified position by locking the screw. Therefore, by the superposition of the actions, the lamp can be placed to reach and stop at any position of a plane formed by the aluminum alloy lamp array frame in a closed mode, pitching and rotating operations of the lamp can be achieved, a complex lamp array network is finally achieved, and the complex requirement of underwater active lighting is met. Each mechanical part is subjected to hard anodic oxidation treatment, so that a very good waterproof and anticorrosion effect can be achieved, and the mechanical parts can be prevented from being corroded and rusted by seawater after long-time underwater operation.
