Light bulb

A tungsten-halogen lamp has a light transmissive, IR coated, filament chamber enclosing a filament, the filament chamber being enclosed within an outer envelope. Fuses are connected to opposite ends of the filament to limit the magnitude and duration of an electrical arc across a break in the filament which, in combination with a fill gas pressure of no greater than 2500 Torr reduces the likelihood of containment failure.

Glare or stray light from a lamp is controlled by determining the location of a filament relative to a major axis of the ellipsoidal portion of a lamp envelope. Once the maximum deviation of the filament from the major axis has been determined, the lamp may be marked with indicia, or immediately secured to a base to assure the location of the filament in the final assembly of the headlamp. Any stray or glare light is then controlled or directed in a predetermined manner.

A fluorescent lamp utilizing a dual layer phosphor coating is disclosed wherein the base layer utilizes a first phosphor mixture and the top phosphor layer in said coating comprises a blend of narrow bandwith emitting phosphors to improve the color rendering capability of these lamps.
