摘要：
The high pressure discharge lamp has a quartz glass lamp vessel having two opposite pinch seals. The pinch seals have major faces which are tapering from an end face towards the discharge space and have raised ridges along their axial edges. The height of the ridges diminishes towards the end faces. The lamp vessel can be obtained from a cylindrical tube by pinching without prior processing.
