[0002] LED lighting fixtures are widely used due to their advantages such as high luminous efficacy, long lifespan, and cost-effectiveness. An LED lighting fixture typically includes a chassis, an LED light source, a functional controller, and a lampshade. The LED light source and functional controller are mounted on the chassis to form the light-emitting element. For wiring the light source, wiring holes need to be made in the chassis. Because the LED light source and functional controller are stacked on the chassis, a visually integrated structure cannot be achieved. Furthermore, since the LED light source is connected to electricity, improving its insulation performance is crucial for the safety of the light-emitting element; poor insulation can lead to the light-emitting element failing to meet safety regulations.
