Bulb pinch technology
Bulb pinch technology is a completely new process developed by OSRAM for manufacturing line voltage halogen lamps. A thin and extremely sensitive filament wire is fixed directly in the bulb by "glass knobs". The lamp construction is more robust as a result. The lamp has a higher life expectancy – even if exposed to vibrations or jolts.
A patented fuse system ensures that the lamp is instantly switched off in critical situations. The lamp can therefore also be used in unshielded luminaires in accordance with IEC 60598-1 (except for HALOLINE for reasons of compliance with standards).
