Patent number: 8308497Abstract: An end cap and socket system for use with a lamp bulb may include an end cap and a socket body. The end cap may include a first cylindrical portion with a first diameter, and a second cylindrical portion with a second diameter smaller than the first cylindrical portion. The socket may a key portion projecting from a front face of the socket. A adaptor for use with a socket may include a key portion. Alternatively, the end can may include a key disk with a key groove cut into the key disk, and the socket may include a key piece with a key rib structured to couple with the key groove. An adaptor for use with an end cap may include an adaptor body portion and a whole, wherein a contact pin can be inserted through the hole. These keying features are intended to prevent improper coupling between mismatched lamps and sockets or insure that the lamp, when mated to the socket, may be rotated in only one direction.Type: GrantFiled: June 12, 2009Date of Patent: November 13, 2012Assignee: Light Sources, Inc.Inventors: Betty Jean Zayas, Christian L.

Patent number: 7816849Abstract: A germicidal lamp having amalgam for controlling mercury vapor pressure contained in a location facilitating efficient high output operation. A low pressure mercury vapor discharge lamp has an amalgam container containing an amalgam positioned behind an electrode out of the arc path or space. The amalgam position is retained during high wall loading of the lamp preventing the amalgam from moving out of position. A heating and cooling element is placed generally at the amalgam position controlling the temperature of the amalgam. Efficient operation with high current loads and resulting high wall loading and temperatures is possible. The temperature control of the amalgam may also be used to dim or modify the illumination output of the lamp. The germicidal lamp is particularly suited to being positioned vertically in a waste water treatment system.Type: GrantFiled: July 31, 2006Date of Patent: October 19, 2010Assignee: Light Sources, Inc.Inventor: Arpad Pirovic

Patent number: 7795813Abstract: 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 with an asymmetrical section or recess 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.Type: GrantFiled: October 10, 2007Date of Patent: September 14, 2010Assignee: Light Sources, Inc.Inventor: Betty Jean Zayas

Patent number: 7569981Abstract: 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.Type: GrantFiled: February 22, 2005Date of Patent: August 4, 2009Assignee: Light Sources, Inc.Inventor: Gino Ciancanelli
