AN OPTICAL DISK DRIVE

摘要

A single end incandescent halogen bulb has an envelope (112) having a sealed cavity (114) containing a halide material, a pinch or press seal (110) at one end, and a coiled wire filament (100) disposed in the sealed cavity (114). Filament legs (102, 104) comprise portions of the coiled wire filament (100) that have been drawn out straight so as to have a diameter which is approximately the same as a diameter of a wire from which filament (100) is formed. A first current supply (106) wire extends through the press seal (110) into the sealed cavity. This first wire (106) has a first clamp (118) formed at a terminal end thereof. The first clamp (118) clamps a first filament (102) leg to establish a first electrical connection and suspend the filament (100) in the sealed cavity (114). A second current supply wire (108) extends into and terminates within the press seal (110). This second wire (108) has a second clamp (116) which clamps a second filament leg (104) to establish a second electrical connection.
