Abstract: A mount (10) for a metal halide arc discharge lamp has a flare (20) including a barrel portion and a frame (32) comprises a clip (40) attached to the barrel portion (30). First and second side rods (50, 60) spaced 180° apart have distal ends (70) and proximal ends (80), with the distal ends being attached to the clip. First and second spaced apart straps (90, 100) connect the side rods intermediate the proximal ends and distal ends. An arc tube (110) is fixed between the first and second straps. The proximal ends diverge outwardly and engage the inner surface of a dome (14) to position one end of the mount. The barrel portion includes two sealed lead-in wires (120, 130). The arc tube includes an electrode (140, 150) in each end (140a, 150a). No electrical connection is made to the frame whereby the frame is electrically isolated.

Abstract: A lamp capsule may be formed with substantially parallelepipedial ends including alignments. A metal strap may surround one end, between the alignments, with first and second oppositely disposed affixation areas of extensions. A glass stem has tubular first portion with outside diameter D. A C-shaped clip is mounted upon the tubular first portion. The clip has height H and inside diameter D1 smaller than the outside diameter D. The clip frictionally engages the tubular first portion. A first frame member has a proximal terminus affixed to the clop and a second frame member has a proximal terminus affixed to the clip opposite the first frame member. The first frame member has a distal terminus affixed to the one affixation area and second frame member has a distal terminus affixed to the other affixation area. The first and second frame members and the metal strap provide the support for the capsule.

Abstract: A mount assembly (10) for an arc discharge vessel has a glass stem (12) having a longitudinal axis (14) that includes a flare (16) with a barrel portion (18) and a seal portion (20) containing at least two relatively rigid stem-leads, (22 and 24), projecting therefrom A relatively rigid wire frame (26) is provided with the frame (26) having a distal end (28) and a proximal end (30). A loop portion (32) is formed at the proximal end (30) and has a diameter substantially equal to the diameter of the barrel (18) and is affixed thereto. The distal end (28) of the wire frame (26) extends away from the barrel portion in a direction transverse to the plane of the loop portion (32). An arc discharge vessel (34, 34a), having a substantially linear configuration and having electrode connections (36) and (38) extending from the ends thereof is positioned on the longitudinal axis (14) and is affixed to the wire frame.

Abstract: A mounting member (50, 50?, 50?, 50??) for an arc tube/shroud combination comprises an annulus (52). The annulus (52) has at least one mounting tab (54) depending from an outer edge thereof and two spaced apart arc tube-pinch seal-engaging ribs (56, 58) spanning the diameter of the annulus for frictionally engaging the pinch seals. Holding tabs (62) depending from the annulus mount the annulus to a shroud. In a preferred embodiment the ribs (56, 58) have upstanding projections (60) that engage the pinch seals and provide the friction fit necessary for holding the pinch seals.

Abstract: A spring clip (10) has a base (12) in a first plane and has an aperture (14) centrally located therein. U-shaped projections (16) and (18) are provided on the base (12) and are formed from first and second upstanding walls (200 and (22) and third and fourth walls (24) and (26), at each end of the base (12). A first lip (28) extends orthogonally between the first wall and second wall in a second plane and a second lip (29) extends orthogonally between the third wall and fourth wall, also in the second plane. The second plane is substantially parallel to the first plane but spaced therefrom. Extensions (30) and (32) are formed with the first wall and the third wall and project away from them. The extension are in substantially the same plane as base (12) and at least one flag (34) can be formed with at least one of the extensions. The flags (34) project away from the extensions (32) in a plane transverse to the first and second planes and allow the clips to be attached to a frame.

Abstract: A high intensity discharge lamp (10) has an outer envelope (12) having a cup-shaped top (14), a hollow center section (16) and a bottom (18) all aligned along a longitudinal axis (20), the bottom (18) including a flare (22) having a pinch seal (24) with in-leads (26, 28) sealed therein.
