Patent number: 6469445Abstract: A metal halide lamp with high color rendering index, greater then 80, with substantially constant color temperature through life. The lamp arc discharge vessel has a small volume, i.e., less than 1 cc, and contains iodides of sodium, scandium, lithium, dysprosium, and thallium along with mercury, a buffer gas and scandium metal. The addition of the scandium metal does not raise the arc discharge vessel temperature and significantly reduces the color temperature decline during life.Type: GrantFiled: June 17, 1999Date of Patent: October 22, 2002Assignee: Osram Sylvania Inc.Inventors: Edward H.

The neck 20 also is symmetrically arrayed about the longitudinal axis 18 and has a substantially closed bottom 21. At least two eyelets, 22, 24, respectively, are sealed in the bottom 21 and a light source capsule 26 is positioned in the concave reflector and aligned with the longitudinal axis 18. The light source capsule 26 has a first end 28 situated in the neck 20 and a second end 30 extending into the concave reflector. The light source capsule 26 comprises a quartz arc tube 32 containing an arc generating and sustaining medium and a surrounding aluminosilicate glass shroud 34.Type: GrantFiled: August 13, 1998Date of Patent: November 14, 2000Assignee: Osram Sylvania Inc.Inventors: John A.

Patent number: 6100634Abstract: An arc discharge tube has electrodes supported by hollow electrode support tubes at each end. A slot is formed in the electrode support tube. One edge of the slot is depressed inwardly to form a concave surface. The slot is located adjacent to the end cap of the arc tube and provides access to the interior of the electrode support tube. After the electrode assembly is sealed into one end of the arc tube, amalgam particles are dispensed into the arc tube. The arc tube is agitated rapidly, causing the amalgam particles to pass through the slot and drop into the interior of the electrode support tube. The amalgam particles are isolated from heat during sealing of the other end of the arc tube.Type: GrantFiled: December 11, 1991Date of Patent: August 8, 2000Assignee: GTE Products CorporationInventor: John A.

Patent number: 5998915Abstract: A mounting assembly for a reflector lamp. The mounting assembly comprises a 0.050" diameter stainless steel rod that has been formed into a three-turn spiral. The spiral surrounds the inner jacket mount assembly of the reflector lamp, and fits into the neck region of the reflector. The lower leg of the spiral either takes the place of, or augments a "dummy" lead presently used in the inner jacket press, so that one or both fit into the reflector eyelet opening in the neck of the reflector. The opposite end of the spiral piece extends upwardly, and is connected to the upper lead of the Model No. PAR30L inner jacket mount assembly of the Model No. MPD70 lamp.Type: GrantFiled: March 12, 1998Date of Patent: December 7, 1999Assignee: Osram Sylvania Inc.Inventors: John A.

Patent number: 5731662Abstract: A metal halide discharge lamp includes an outer evacuated sealed glass envelope having a domed end and a socket end spaced from the domed end along a longitudinal axis. The socket end is subject to high temperature sealing fires during the lamp manufacturing process. A getter material is contained in the envelope for removing gaseous materials therefrom, the getter material being positioned in the envelope in an area of the lamp remote from the socket end. A pair of electrical conductors extend into the interior of the glass envelope and an arc tube containing an arc sustaining chemical fill and including a pair of spaced electrodes is electrically connected to the electrical conductors for creating an electric arc during operation of the lamp. The getter material comprises about 70 weight percent zirconium, about 24.6 weight percent vanadium, and about 5.4 weight percent iron. The activation temperature of the getter is in the range of 400.degree.-500.degree. C.Type: GrantFiled: July 2, 1997Date of Patent: March 24, 1998Assignee: Osram Sylvania Inc.Inventors: Richard A.
