Patent number: 10109473Abstract: A laser sustained plasma lamp includes a mechanically sealed pressurized chamber assembly (330) configured to contain an ionizable material. The chamber assembly is bounded by a chamber tube (310), an ingress sapphire window (340), a first metal seal ring (320) configured to seal against the chamber tube ingress end and the ingress sapphire window, an egress sapphire window (342), and a second metal seal ring (322) configured to seal against the chamber tube egress end and the egress sapphire window. A mechanical clamping structure (350, 355) external to the chamber assembly is configured to clamp across at least a portion of the ingress sapphire window and the egress sapphire window. The ingress sapphire window and the egress sapphire window are not connected to the chamber tube via welding and/or brazing.Type: GrantFiled: January 26, 2018Date of Patent: October 23, 2018Assignee: Excelitas Technologies Corp.Inventors: Rudi Blondia, Douglas A.

Patent number: 8242671Abstract: A short arc lamp comprises front and back subassemblies including mating weld rings, whereby the lamp can be assembled and sealed through welding of the weld rings. Each subassembly includes a number of self-aligning components to facilitate assembly and improve alignment accuracy. The metal body of the lamp can have a cooling projection portion, which can be received by a heat sink to remove heat from near the anode. A heat sink also can be formed as part of the metal body. The lamp reflector can be a drop-in reflector, or can be formed as part of the metal body through a process such as metal injection molding. A single strut can be used to position the cathode, which can be part of the sleeve or received by a portion of the sleeve. A trigger electrode can be used to simplify the power supply for the lamp.Type: GrantFiled: February 4, 2010Date of Patent: August 14, 2012Assignee: Excelitas Technologies Singapore Pte, LtdInventors: Rudi Blondia, John Kiss, Douglas A.

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

Publication number: 20020145875Abstract: A water-cooled arc lamp comprises a two concentric cylindrical glass envelopes. A circulation of high purity water and ethylene glycol is maintained between the envelopes which form a water jacket. Such water mixture is highly transparent to light at the relevant wavelengths. A pair of anode and cathode electrodes in a xenon atmosphere is disposed inside the inner envelope. The cooling water mixture is pumped at a sufficiently high flow rate to prevent water from boiling at the glass to water surfaces and thereby suppress bubbles. A safety interlock flow switch is able to interrupt arc lamp operating power if the water circulation fails. An external parabolic reflector compensates for the light path diffraction distortions that occur as the light passes through the water jacket. In alternative embodiments, the water mixture is color doped to color filter the output light.Type: ApplicationFiled: April 10, 2001Publication date: October 10, 2002Applicant: PerkinElmer Optoelectronics N.C., Inc.Inventors: Roy D.

Patent number: 6285131Abstract: A xenon arc lamp is provided with an improved cathode support. The improvements reduce the number of assembly procedures and parts needed to produce an arc lamp. Such reduces the overall cost of manufacturing. The cathode suspension system is made by starting with a single piece of sheet Kovar material that is formed into a cup. Pieces are cut from the bottom of the cup such that three webs connect the outside ring to the center. The three webs each have a flap that is then folded back 90° to form a rigid strut arm. A tungsten cathode electrode is brazed at the center and apex of the three struts with a sleeve that helps bridge the fillet area.Type: GrantFiled: May 4, 1999Date of Patent: September 4, 2001Assignee: EG&G ILC Technology, Inc.Inventors: John Kiss, Daniel Joseph O'Hare, Roy D.

Patent number: 5672931Abstract: A spectral filter and mounting assembly comprising a flat quartz disk with coatings to control the light spectrum, a heat transfer adapter, a split-ring retainer for use in a drop-in arc lamp assembly that includes an arc lamp with fitted cathode and anode heat sinks each including a thin-wall copper strip that is brazed in pleated folds between inner and outer cylindrical rings to create cooling fins. The drop-in lamp assembly also includes an insulative sleeve in which the arc lamp and heat sinks are disposed and a pair of connection bushings piercing the wall of the sleeve and providing an electrical connection to the arc lamp outside the sleeve. The arc lamp includes a copper heat conduction flange that surrounds a front window reduced in diameter from the diameter of the arc lamp. The flange conducts heat generated in the window and the spectral filter during operation directly to the cathode heat sink. Both heat sinks are forced-air cooled by the fan, thus cooling the window and the spectral filter.Type: GrantFiled: October 2, 1995Date of Patent: September 30, 1997Assignee: ILC Technology, Inc.Inventors: John Kiss, Roy D.

A flush-mount receptacle for the drop-in lamp assembly includes a housing with a fan axially positioned behind the arc lamp and heat sinks when they are in place in the sleeve and dropped-into the housing. A glass epoxy board attached to the housing supports and insulates electrical terminals that contact the bushings to power the arc lamp. The arc lamp includes a copper heat conduction flange that surrounds a front window reduced in diameter from the diameter of the arc lamp.Type: GrantFiled: April 13, 1995Date of Patent: October 1, 1996Assignee: ILC Technology, Inc.Inventors: Roy D.
