Abstract
An LED lamp is configured to be connected to a leakage protection switch. The LED lamp includes one or more light emitting diodes, a control circuit, a light board and an enclosure. The control circuit is configured to be coupled to the leakage protection switch by a hot connector and a neutral connector. The light board is a printed circuit board that includes a track that surrounds a light module. A branch of the hot connector is directly coupled to the track and the light module is coupled to the control circuit by a hot line and a neutral line. The enclosure supports the control circuit and the light board. When water contacts the track, at least a portion of a current flowing through the hot connector enters a ground conductor, thereby causing the leakage protection switch to electrically disconnect the LED lamp from a power supply.
