Ultraviolet lamp for use in water purifiers

A socket designed to couple with a lamp base comprising:

• a cylindrical body having an end surface;
• a central step portion extending perpendicular to the end surface, the central step portion comprising:
• a first flat face extending perpendicular to the end surface;
• and
• a second flat face extending perpendicular to the end surface;
• a first upper connector provided within a recess formed in the central step portion;
• a second upper connector provided within a recess formed in the central step portion;
• a first lower connector provided within a recess formed in the end surface;
• and
• a second lower connector provided within a recess formed in the end surface.

A lamp base and socket assembly for use with a lamp bulb, the assembly comprising:

• a lamp base structured to fit on an end of a lamp bulb, the lamp bulb comprising:
• a cylindrical lamp base body having a base end surface;
• a first step portion and a second step portion, each comprising a flat face extending perpendicular to the base end surface, and a raised face that is perpendicular to the flat face;
• a first upper pin connector provided on the raised face of the first step portion and extending perpendicular to the first step portion;
• a second upper pin connector provided on the raised face of the second step portion and extending perpendicular to the first step portion;
• and
• a first and second lower pin connector provided on the base end surface and extending perpendicular to the end surface;
• and
• a socket structured to couple with the lamp base, the socket comprising
• a cylindrical socket body having a socket end surface;
• a central step portion extending perpendicular to the socket end surface, the central step portion comprising a first flat face extending perpendicular to the end surface;
• and a second flat face extending perpendicular to the end surface;
• a first upper connector provided within a recess formed in the central step portion;
• a second upper connector provided within a recess formed in the central step portion;
• a first lower connector provided within a recess formed in the end surface;
• and
• a second lower connector provided within a recess formed in the end surface;
• wherein the first lower connector and second lower connector are structured to couple with the first upper pin connector and the second upper pin connector, respectively;
• the first upper connector and the second upper connector are structured to couple with the first lower pin connector and the second lower pin connector;
• and
• the central step portion is structured to fit between the first step portion and the second step portion when the socket and the lamp base are coupled.

An adaptor structure for use with a lamp base comprising a first pin connector extending from an end of the lamp base, the adaptor comprising:

• a flat face;
• an end face formed perpendicular to the first flat face;
• and
• a key recess formed in the flat face;
• wherein the adaptor is structured to attach to the end of the lamp base such that the flat face is perpendicular to the end of the lamp base and the first pin connector extends through the adaptor.
