[0002] Underground lamps are widely used in the field of scientific and technological lighting in my country. They can be used in squares, restaurants, private villas, gardens, conference rooms, exhibition halls, community landscaping, stage bars, shopping malls, parking lots and other places. Because they are buried in the ground for lighting, they are called underground lamps. Underground lamps can have a good decorative effect on the environment, and at the same time they will not occupy space in the venue and will not affect normal traffic, so they are very popular. However, underground lamps are generally buried under the ground, and the poor waterproof effect can easily cause a short circuit in the circuit, so the waterproof construction problem is particularly important.

For example, when using underground lamps to decorate landscape trees, it is necessary to change the direction of the underground lamp on the landscape tree according to the environment or requirements. At this time, the angle of the underground lamp needs to be adjusted. At present, in the construction of traditional underground lamps, the lamp body and its angle adjustment device are installed on the ground or partially exposed to the outside, which has poor waterproof effect, and the parts are prone to rust and leakage, and the circuit is prone to short circuit and malfunction.
