Abstract

Eine Hochdruckentladungslampe hat ein keramisches Entladungsgefäß, das in einem Außenkolben untergebracht ist, wobei der Außenkolben außerdem von einem Splitterschutz umgeben ist, der eng am Außenkolben anliegt.A high pressure discharge lamp has a ceramic discharge vessel housed in an outer bulb, the outer bulb being further surrounded by a shatter shield which closely abuts the outer bulb.

Insbesondere ist der Splitterschutz ein Schrumpfschlauch.
