ABSTRACT:
The low pressure sodium discharge lamp has an outer envelope (1) in which a U-shaped discharge tube (10) is accommodated. A mica disk (20) having holes (21 ) through which pinches (11) of the discharge tube extend, keeps the discharge tube centered. The mica disk (20) has teeth (22) at its periphery, which are bent towards the lamp base (5) and clampingly engage the outer envelope. The disk allows for the outer envelope to be fused to a flared tube (3) in a drop-seal process and provides several additional features.
