A through hole 222 for the grounding wire 6 to pass through is provided on the housing 2. The end of the grounding wire 6 is electrically connected to the first magnet 5.

[0021] In the present utility model, the circuit board 3 is electrically connected to the first magnet 5 through the grounding wire 6, and the first magnet 5 is connected to the magnetic material. In this way, during use, the static electricity on the circuit board 3 can be conducted to the wall where the LED point light source is installed through the grounding wire 6, the first magnet 5, and the magnetic material, avoiding the accumulation of static electricity in the LED point light source and improving the use safety and lifespan. Moreover, the first magnet 5 on the housing 2 can be magnetically fixed to the magnetic material on the mounting base 1, realizing the quick installation and disassembly of the housing 2.
