USE OF GLASS CERAMICS

摘要

The invention relates to novel uses of glass ceramics, wherein glass ceramics, in particular, in the form of a glass ceramic tube, are used. Said glass ceramics contain 0 - less than 4 wt % P205 and 0 less than 8 wt- % CaO. The tubes can be used in multiple areas of application and/or in multiple types of lamps, for example in general lighting or car lights and in heat radiators, such as halogen lamps or incandescent lamps, and/or in high pressure discharge lamps or low pressure discharge lamps. The glass ceramics, can also, in particular, be minimised in order to form known backlighting in conjunction with background lighting of flat screens. Said type of glass ceramics have excellent spectral transmission in the visible wave length rang and are solarisation stable and absorb strong UV light.
