Lamp module group

A method for assembling a lighting assembly, the method comprising:

• attaching a mask to a first housing of a lamp module group to redirect light emitted from an LED lamp board of the lamp module group, the LED lamp board positioned within a cavity defined by the first housing, the LED lamp board configured to emit light through a housing opening defined at a first housing end of the first housing;
• and
• attaching a second housing to a protruding column of the first housing to supply power to a first concentric terminal of the lamp module group from a second concentric terminal of the second housing, comprising:
• inserting an outer conductive pipe and an inner conductive pipe of the first concentric terminal between a conductive ring and a conductive post of the second concentric terminal to form a first electrical connection between the outer conductive pipe and the conductive ring;
• and
• inserting the conductive post into the inner conductive pipe to form a second electrical connection between the conductive post and the inner conductive pipe, the first concentric terminal extending through the protruding column.

A lighting assembly comprising:

• a lamp module group comprising:
• 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, the first concentric terminal comprising an outer conductive pipe and an inner conductive pipe;
• and
• a second housing comprising a second concentric terminal, the second concentric terminal comprising a conductive ring and a conductive post, the conductive ring positioned between the outer conductive pipe and the inner conductive pipe, the conductive post received within the inner conductive pipe, 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.
