Patent number: 8853931Abstract: An electrodeless plasma lamp having a lamp body and a power source configured to provide radio-frequency (RF) power via a feed to the lamp body is provided. The lamp includes a first conductive element and a second conductive element. The first conductive element has a first side with a first protrusion. The second conductive element has a second side with a second protrusion. The first side and second side face each other and spaced apart by a first distance and configured to couple the RF power via an electric field to a fill to form at least one plasma arc. The first protrusion and the second protrusion extend towards each other and are spaced apart by a second distance that is less than the first distance. The first and second protrusions may provide localized enhancement of the electric field at the first side and the second side.Type: GrantFiled: December 17, 2010Date of Patent: October 7, 2014Assignee: Luxim CorporationInventors: Abdeslam Hafidi, Dan O'Hare, Marc DeVincentis

Patent number: 8436546Abstract: An electrodeless plasma lamp and method of generating light are described. The lamp may comprise a lamp body, a source of radio frequency (RF) power and a bulb. The lamp body may comprise a solid dielectric material and at least one conductive element within the solid dielectric material. The source of RF power is configured to provide RF power and an RF feed configured to radiate the RF power from the RF source into the lamp body. The bulb is positioned proximate the lamp body and contains a fill that forms a plasma when the RF power is coupled to the fill from the lamp body. The at least one conductive element is configured to concentrate an electric field proximate the bulb.Type: GrantFiled: February 22, 2012Date of Patent: May 7, 2013Assignee: Luxim CorporationInventors: Marc DeVincentis, Abdeslam Hafidi, Richard Gilliard, Dan O'Hare

Patent number: 8319439Abstract: An electrodeless plasma lamp and a method of controlling operation of a plasma lamp are provided. The plasma lamp may a power source to provide radio frequency (RF) power and a lamp body to receive the RF power from a feed. The lamp body may comprise a dielectric material having a dielectric constant greater than 2 and bulb is provided that contains a fill that forms a plasma that emits light when at least a portion of the RF power is coupled to the fill. A light guide directs light from the bulb to a photosensor that is shielded from light output from a front side of the lamp body. The lamp includes a drive circuit to control operation of the lamp based on a level of light detected by the photosensor.Type: GrantFiled: September 18, 2009Date of Patent: November 27, 2012Assignee: Luxim CorporationInventors: Gregg Hollingsworth, Marc DeVincentis, Anthony D.

Patent number: 8294382Abstract: In various exemplary embodiments, an electrodeless plasma lamp includes a bulb configured to be coupled to a source of radio frequency (RF) power. The bulb contains a fill that forms a plasma when the RF power is coupled to the fill. An electrically-conductive convex shield is positioned proximate to the bulb with a convex surface of the shield being distal to the bulb. A resonant structure having a quarter wave resonant mode includes a lamp body having a dielectric material having a relative permittivity greater than 2 with an inner conductor and an outer conductor. The source of RF power is configured to provide RF power to the lamp body at about a resonant frequency for the resonant structure.Type: GrantFiled: January 6, 2010Date of Patent: October 23, 2012Assignee: Luxim CorporationInventors: Marc DeVincentis, Dan O'Hare

Patent number: 7291981Abstract: A short arc lamp incorporates a cylindrical reflector body having a reflector cavity opening to a first end and an anode aperture through a base surface at a second end. The body has a step at the second end. A front sleeve with a step for positional engagement of a land is received over the first end of the reflector body. A cathode support is received within the second end of the front sleeve and includes a ring to engage a second oppositely oriented positioning step. A window mount received within the second end of the front sleeve abuts a front surface of the ring. A highly conductive base concentrically supporting an anode received through the anode aperture has a flange in flush abutment with the base surface for braze attachment.Type: GrantFiled: July 13, 2004Date of Patent: November 6, 2007Assignee: PerkinElmer, IncInventors: John Kiss, Dan O'Hare, James Hyunh, Rudi Blondia
