Abstract: 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.

Abstract: A multi-functional shroud/arc tube support or clip (40a) for a high intensit y discharge lamp (10). The support (40a) has one end (42) formed to engage a shroud (20) . The one end (42) is formed as an arcuate member (43). A middle portion (44) is forme d of separated, depending legs (46, 48) defining a space (50) therebetween for clasping the substantially rectangular pinch seal (52) of a quartz arc tube (14). The central section (53) is formed to clasp the cylindrical capillary (54) of a ceramic arc tube (14a). The central section (53) comprises the bight of a pair of U-shaped legs and the bights are provided with opposing, substantially hemi-cylindrical concavities (53a).

Abstract: An hermetically sealed arc tube which comprises a hollow body having oppositely disposed ends aligned along a longitudinal axis and containing an arc generating and sustaining medium therein. An electrode is positioned in each end of the hollow body and an ionization zone is positioned adjacent to one of the ends and is a part thereof. The ionization zone is exposed to an atmosphere different than the arc generating and sustaining medium.

Abstract: 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.

Abstract: A reflector lamp 10 has a vitreous outer envelope 12 formed of a concave reflector 14 and a light-transmitting 16 cover peripherally sealed thereto. The concave reflector and cover are symmetrically arrayed about a longitudinal axis 18 and a substantially cylindrical, hollow neck 20 having a given depth is affixed to the concave reflector opposite the cover. 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. First and second conductive lead-ins 36, 38, respectively, are sealed into a first seal 40 formed at a first end 42 of the shroud 34. Each of the lead-ins 36, 38 has a first portion 44, 46, respectively, sealed in one of the eyelets 22, 24. The first conductive lead-in 36 has a second portion 48 extending interiorly of the shroud and connecting a first electrode 50 of the arc tube and contains a bend or offset 49 to take expansion differences during operation. The second lead-in 38 has a second portion 54 terminating within the first seal 40. An outer conductor 56 has a first end 58 sealed in a second end 60 of the shroud 34 and connects a second electrode 62 of the arc tube 32. A middle section 64 of the outer conductor 56, which is surrounded by an electrically insulating sleeve 57 for at least part of its length, extends exteriorly of the shroud 34 and has a second end 66 connected to the second said lead-in 38. A conventional screw base 68 completes the lamp.

Abstract: A metal halide discharge lamp comprises an outer evacuated sealed glass envelopehaving 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 400-500.degree.C.

Abstract: An arc tube for a discharge lamp comprises an hermetically sealed hollow body containing an arc generating and sustaining medium therein and having first and second ends. An electrode receiving capillary extends from each end and an electrode structure is positioned in each of the capillaries. Each of the electrode structures comprises a proximal, electrode end projecting into the interior of the hollow body, a distal end projecting exteriorly of the capillary, and an intermediate section therebetween, a first area of the intermediate section being sealed to the capillary in an hermetic manner and a second area of the intermediate section being exposed to the medium. A starting aid comprises an electrically conducting member surrounding the capillary extending from the first end at the second area of the intermediate section and is electrically connected to the distal end of the electrode structure positioned in the second end. The starting aid provides a capacitively coupled ionization mechanism for starting the lamp.
