## Abstract

A waterproof LED controller, including a housing, a power cord component on one side of the housing, and a connecting socket on the other side of the housing. In addition to forming a certain level of waterproofing through ultrasonic welding between the first housing and the second housing, the locating protrusion on the first housing and the locating groove on the second housing are also ultrasonically welded. Furthermore, a welding groove matching the welding protrusion on the connecting socket is provided on the inner surface of the first mounting hole, allowing the welding protrusion and welding groove to be ultrasonically welded. Additionally, waterproofing at the switch through-hole is achieved by supporting the circuit board with a first support pillar, causing the circuit board to press against rubber buttons. This results in a sealed structure, ultimately achieving the overall waterproofing.

## Claims
