Abstract
The high pressure discharge lamp has containment structure in the outer envelope which encloses the discharge vessel. The containment structure consists of a glass cylindrical sleeve closed at its ends by a metal plate. The plates, the cylindrical sleeve and the discharge vessel are combined as a subassembly. The metal plates are provided with tongues bearing on the glass cylindrical sleeve and the outer envelope. The lamp has a flexible conductor which extends from the current lead-through conductor remote from the stem to the lamp stem and bears on the outer envelope. The containment structure prevents failure of the outer lamp envelope in the event of explosive failure of the discharge vessel.
