Abstract (en)
An arc tube (12, 46, 48), provided for a high pressure discharge lamp, includes a discharge chamber (24) containing a fill. Electrical conductors (26, 28) extend into the discharge chamber (24) to form electrodes (32, 34). The electrical conductors (26, 28) are sealed in the arc tube (12, 46, 48) by a single pinch seal portion (30). At the interface (44) of the discharge chamber (24) and the pinch seal portion (30), the discharge chamber has at least in part a non-concave outline. This outline may be rectilinear or convex.
