Lamp, particularly vehicle lamp, has spiral-wound filament with spiral body and two spiral ends, where spiral ends are connected with power supply lines

摘要

#CMT# #/CMT# The lamp has spiral-wound filament (3) with a spiral body and two spiral ends. The spiral ends are connected with power supply lines. One of the power supply lines is arranged within the spiral body. The power supply line is electrically insulated against the spiral body by an insulating device. The insulating device is made of quartz glass or heat-resistant ceramic. #CMT# : #/CMT# An independent claim is included for a method for manufacturing a lamp. #CMT#USE : #/CMT# Lamp, particularly vehicle lamp. #CMT#ADVANTAGE : #/CMT# The spiral ends are connected with power supply lines, and one of the power supply lines is arranged within the spiral body, and hence ensures increased vibration resistance. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic side view of a filament lamp with spiral-power supply geometry. 1 : Lamp vessel 2 : Base 3 : Spiral-wound filament 4,5 : Power supply wires 6,7 : Electric connections.
