Abstract: A lighting assembly can include a lamp module group including a first housing defining a protruding column, the first housing defining a cavity, the first housing defining a housing opening to the cavity positioned opposite from the protruding column; a power supply driving module positioned within the cavity; and a first concentric terminal connected in electrical communication with the power supply driving module, the first concentric terminal extending through the protruding column; and a second housing including a second concentric terminal, the second housing receiving a portion of the first housing, the second concentric terminal connected in electrical communication with the first concentric terminal, the second concentric terminal configured to supply power to the power supply driving module through the first concentric terminal.

Abstract: An electronic module group can include an electronic module including a first housing defining a housing cavity; a power supply driving module positioned within the housing cavity; and a first concentric terminal connected in electrical communication with the power supply driving module by a first wire and a second wire; and a second concentric terminal rotatably connected in electrical communication with the first concentric terminal, the second concentric terminal configured to transmit power to the first concentric terminal.
