Electronic module group

A lamp module comprising:

• a first housing comprising a light holder portion, a shaft portion, and a fixing rod, the shaft portion configured to tilt relative to the light holder portion about the fixing rod, the light holder portion defining a first housing cavity, the shaft portion defining a second housing cavity, the shaft portion defining a threaded shaft;
• an LED lamp board positioned within the first housing cavity, the LED lamp board configured to emit light through a bore of the light holder portion;
• a power supply driving module positioned within the second housing cavity;
• and
• a first concentric terminal connected in electrical communication with the power supply driving module, the first concentric terminal positioned at least partially within the shaft portion, the first concentric terminal configured to rotatably connect in electrical communication with a second concentric terminal, the concentric terminal comprising an inner conductive sleeve and an outer conductive sleeve, the inner conductive sleeve configured to receive a conductive post of the second concentric terminal to establish a first electrical connection, the outer conductive sleeve configured to contact a conductive spring of the second concentric terminal to establish a second electrical connection, the first concentric terminal configured to maintain the first electrical connection and the second electrical connection regardless of a rotational orientation of the first concentric terminal relative to the second concentric terminal.

A lamp module comprising:

• a housing comprising a light holder portion and a shaft portion, the light holder portion configured to tilt relative to the shaft portion, the light holder portion defining a first housing cavity, the light holder portion defining a first wire opening that is in communication with the first housing cavity, the first housing cavity being at least partially filled with a filler material, the shaft portion defining a second housing cavity, the shaft portion defining a second wire opening that is in communication with the second housing cavity, the light holder portion defining a first end and a second end, the first end connected to the shaft portion, the second end defining internal threading within the first housing cavity;
• an LED lamp board positioned within the light holder portion;
• a retention insert engaging the internal threading within the first housing cavity, the retention insert securing the LED lamp board within the first housing cavity;
• a lens positioned over an LED of the LED lamp board, the lens at least partially encircled by the retention insert;
• a power supply driving module connected in electrical communication with the LED lamp board;
• a first concentric terminal positioned at least partially within the shaft portion, the first concentric terminal connected in electrical communication with the power supply driving module, the first concentric terminal configured to rotatably connect in electrical communication with a second concentric terminal to supply power to the power supply driving module, the first concentric terminal comprises an inner conductive sleeve and an outer conductive sleeve, the inner conductive sleeve configured to receive a conductive post of the second concentric terminal to establish a first electrical connection, the outer conductive sleeve configured to contact a conductive spring of the second concentric terminal to establish a second electrical connection, the first concentric terminal configured to maintain the first electrical connection and the second electrical connection regardless of a rotational orientation of the first concentric terminal relative to the second concentric terminal;
• and
• at least one wire connected in electrical communication with at least one of the LED lamp board, the power supply driving module, and the first concentric terminal, the at least one wire extending from the first housing cavity to the second housing cavity through the first wire opening and the second wire opening, the filler material forming a seal around the at least one wire.
