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.

A tungsten-halogen lamp for use in an automobile headlight comprises a tubular sealed glass capsule containing two coiled tungsten filaments for high and low beam operation, respectively. The low beam filament is disposed substantially orthogonal to a vertical plane containing the lamp axis, with the center of that filament length having a predetermined offset from that vertical plane and being disposed at or near the focal point of the reflector. The high beam filament is disposed substantially parallel to the lamp axis on the opposite side of the vertical plane from at least a major portion of the low beam filament. The filaments are spaced apart with the high beam filament lying in a horizontal plane spaced below the low beam filament, and the axis of the high beam filament orthogonally intersects a plane containing in the axis of the low beam filament.

A tungsten-halogen electric lamp having permeable means closing an outer envelope. Such non-hermetic means may be relatively free-breathing or weather-tight. Tungsten-halogen lamps with permeable means may be manufactured more simply and economically than those currently available.

A method for mounting a filament in a double ended incandescent lamp capsule. A filament assembly, including a filament, filament supports attached to each end of the filament and an external lead connected to each filament support, is located in a tubular lamp envelope. The position of the filament relative to the lamp envelope is determined, and the filament is moved to a predetermined position relative to the lamp envelope, if necessary. Then, the lamp envelope is heated sufficiently to cause the lamp envelope to deform into contact with at least one of the filament supports so as to securely anchor the filament support. The heating of the lamp envelope in regions of the filament supports can be performed simultaneously or at different times. One or both filament supports can be anchored by the tacking process.

Filament supports for supporting and centering a filament in a double-ended lamp envelope include an inlead portion defining a central axis, a filament attachment portion and a centering portion interconnecting the inlead portion and the filament attachment portion. The centering portion contacts an inner surface of the lamp envelope at a plurality of discrete, circumferentially spaced-apart contact regions that are substantially equally spaced from the central axis. The filament supports are attached to opposite ends of the filament for accurately centering the filament within the lamp envelope. The filament supports are particularly useful in a tubular incandescent lamp capsule having an infrared reflective coating on its outer surface.

A double-enveloped tungsten halogen incandescent lamp having a light-source capsule containment device wherein a knitted wire mesh surrounds the light-source capsule and may be anchored to the capsule, stem, or lead-in wires. In the event of a burst of the light-source capsule, the containment mesh substantially restricts shards of the capsule from shattering the outer envelope of the lamp. In some embodiments, a crumpled portion of the containment mesh is positioned above the capsule and provides a collision-absorbing cushion in the event the capsule and mesh are propelled against the outer envelope by the burst of the light-source capsule whereby further protection against the shattering of the outer envelope is provided. Lamps with such containment devices have improved operational safety characteristics.
