Description

Technical Field

[0001] This utility model belongs to the technical field of LED strip controllers, specifically relating to a novel RGB LED strip controller. Background Technology

[0002] LED RGB lighting is a common type of lighting fixture used for advertising and decorative purposes. It consists of a lamp body and a controller. The lamp body contains a light strip and a circuit board. Each LED has a different coded value, and the corresponding drive is controlled by the RGB lighting strip controller. Existing RGB lighting strip controllers include a housing and a control circuit board inside the housing, with the control circuit board connected to the light strip in the lamp body. While this meets general usage requirements, the sealed housing of existing RGB lighting strip controllers is not conducive to heat dissipation. Furthermore, to ensure sealing and waterproofing, corresponding gaskets are used, with both inlet and outlet wires passing through them. Although this meets general usage requirements, its sealing performance is relatively limited, allowing external moisture to easily enter the interior through the wires, thus affecting the stability and effectiveness of the controller.
