Abstract

An incandescent lamp bulb, intended primarily for otoscopes, ophthalmoscopes and similar instruments, has a lamp envelope 1 mounted in a metal tube 6 with an air gap 12. The envelope is located only by an elastomeric ring 13 and the conical end of the tube. The internal surface of the tube is bright metal plated. This plating, the air gap, and the small area of contact with the surroundings ensure that the envelope, which is preferably a halogen-containing envelope, runs hot. The conical tube end has slots 11 such that the tube end can be deformed in order to centre the filament 3 accurately in the bulb body. <IMAGE>
