A wire guard ring is also provided at the through hole 7 to protect the connecting wire and seal the through hole 7. The outer shell is waterproof and sealed as a whole through the sealing member, thereby improving the reliability and service life of the power supply shell.

[0043] As a feasible approach, a heat dissipation structure is provided on the top cover 1 .

[0044] In this solution, based on the heat dissipation characteristics of the LED driver power supply, a heat dissipation structure of a corresponding type and range is set on the top cover 1 according to the actual heat generation of the power supply, and a material with a thermal conductivity coefficient higher than the preset thermal conductivity parameter can be used for the top cover 1 and the housing 3.
