摘要：
A double-ended, double-sided pinch seal discharge lamp has pinch seals at posite ends of a discharge vessel, in which the broad side surfaces of the pinch seal, retaining a molybdenum foil (8) is formed with lateral constrictions or indentations (16) located at the transition zone between the pinch seal and the bulbous or discharge vessel portion (3). Preferably, excess glass material from the side surfaces or ribs (14) formed on the side surfaces of the pinch or press seal is squeezed, in the transition zone, towards the bulb or central region (3) during the pinch sealing process to form reinforcement ribs (17), thereby strengthening the transition zone between the pinch seal (5) and the bulb portion (3) of the lamp.
