Abstract: An ultraviolet gas discharge lamp having contact pins extending downward from a base cap toward an opposing end. The lamp is placed within a conduit or duct for disinfecting air or water flowing within the conduit. The reverse contact pins that extend toward the opposing end mate with contact holes in a socket attached to the conduit through which the lamp is inserted. The lamp is only energized when the lamp is fully inserted into the duct and is de-energized upon removing the lamp from the duct. A shield protects the pins. A window may be place in the base cap so as to visually confirm that the lamp is energized and radiating. A key and mating receiver may be used on the base cap and the socket so as to prevent accidental insertion of an inappropriate lamp.

Abstract: A safety lamp connector assembly for use with at least one of more lamps which may include: an end cap for the lamp and having end cap clips; an intermediate snap action socket body for receiving the end cap; a socket base comprising: resilient clip arms with clip section on their ends which snap clips to the end cap clips with the intermediate snap action socket body located between the end cap and the socket base.

Abstract: A lamp is provided having terminal pins mounted on and extending outwardly along a longitudinal axis of an end cap of the lamp. The pins are offset relative to one another along the longitudinal axis. The end cap has semi-circular, parallel surfaces at one end, and the pins extend outwardly from the respective semi-circular, parallel surfaces. A barrier wall extends substantially perpendicularly between the semi-circular surfaces. In a first embodiment, a male extension member extends outwardly from the barrier wall along at least a portion of the lower semi-circular surface. This male extension is coextensive with the upper semi-circular surface. Alternatively, in a second embodiment, a female recess is provided through the boundary wall. This recess again extends between the upper and lower semi-circular surfaces.

Abstract: An ultraviolet gas discharge lamp having contact pins extending from a base cap toward an opposing end in reverse pin fashion. The lamp is placed within a conduit or duct for disinfecting air or water flowing within the conduit. The reverse contact pins that extend toward the opposing end mate with contact holes in a socket attached to the conduit through which the lamp is inserted. The lamp is only energized when the lamp is fully inserted into the duct and is de-energized upon removing the lamp from the duct. A shroud may protect the pins. A window may be incorporated in the base cap so as to visually confirm that the lamp is energized and radiating. A key and mating receiver may be used on the base cap and the socket so as to prevent accidental insertion of an inappropriate lamp. A locking latch may also be included.
