Abstract: A holder (50) for an arc tube-shroud assembly (52) (see FIGS. 3-5) comprises: a planar disc (54) having a plurality of shroud-holding arms (56) peripherally spaced about the disc and extending in a first direction (58). At least two arc tube holding arms 60 extend in an opposite direction (62) for positioning an arc tube (52a) laterally within a shroud (52b); and at least one arc tube locking tab (64) extends in the opposite direction (60) for positioning the arc tube (52a) axially within the shroud (52b). The planar disc (54) is provided with a plurality of venting apertures (82) sized to allow egress of pressurized gases but inhibit passage of axially-propelled arc tube shards in the event of a non-passive failure of an arc tube.

Abstract: A lamp (50) has a lamp envelope (10) having a body (12) with a bottom (14) having a lead-in accepting channel (18); a seat (22) formed with the bottom (14) adjacent one of the lead-in accepting channels; a light source capsule (51) having two electrical lead-ins (52, 54) extending therefrom and through the lead-in accepting channel (18; and an electrical contact (24) having a first depending leg (26), an intermediate transverse portion (28) including a seat engager (30) adapted to cooperate with the seat (22), and a projecting leg (32) extending away from the intermediate transverse portion (28) and along a side (34) of the bottom (16), the first depending leg (26) being in mechanical and electrical contact with one of the lead-ins (54).

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 mount assembly (10) for a lamp that comprises a light source (12) having two ends (14, 16) separated by a hollow middle portion (18). Light source capsule (12) can be an arc discharge vessel and the ends (14) and (16) are substantially parallelepipedial. The ends (14) and (16) are also provided with alignment segments (60) in the form of spaced apart beads (62) and (64). A metal strap (20) surrounds one of the ends, for example, (14), and is positioned between the beads (62) and (64), and has first and second oppositely disposed affixation areas, (22, 24); which can be in the form of extensions (22a) and (24a). A glass stem (26) has a tubular first portion (28) with an outside diameter D. A substantially C-shaped clip (30) is mounted upon the tubular first portion (28). The C-shaped clip (30) has a given height H and an inside diameter D1 that is smaller than the outside diameter D whereby the clip frictionally engages the tubular first portion.

Abstract: A frame clip (100) for mounting a light source (for example, an arc tube 32) in a lamp. The frame clip (100) comprises a substantially oval body having a longitudinal axis (110) with an opening (112) therein parallel to the longitudinal axis and having a given height, a first inside dimension D1 and a second inside dimension D2, and wherein the second dimension D2 is greater than D1.

Abstract: An assembly (10) for a lamp. The assembly 10 includes a light source (12) having a center chamber (14) and opposite ends (16, 18), arrayed along a longitudinal axis (19). The ends (16, 18) are cylindrical in cross-section. A tubular shroud (20) surrounds the light source (12) and is coaxial with the longitudinal axis (19). The light source (12) is mounted within the shroud (20) by spring clips (26) one of which is mounted at either end of the shroud. The spring clips each include a base (28) lying in a first plane and having an aperture (30), for example, a star-shaped aperture, centrally located in the base. The apertures (30) in the two spring clips frictionally engage one of the ends (16, 18) of the light source (12). Each of the spring clips (26) has a U-shaped projection (32) at and end (33) of the base (26). The U-shaped projection comprises first and second upstanding walls (34, 36) joined by a first lip (38) that extends in a second plane and is fitted over the wall of the shroud (20).

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.
