Abstract
The invention proposes a lamp (1), in particular a halogen incandescent lamp for system voltage, having a luminous element (8), which is retained by pinches (10a, 10b) which are in the form of funnel-shaped turned-in sections in the end face (3) of the lamp vessel (2), the pinches (10a, 10b) being oriented essentially axially with respect to the longitudinal axis of the lamp (1).
Claims16
An electric lamp having
- a lamp vessel, having a wall defining an enclosed volume, and a first power supply line and a second power supply extended through the wall in a sealed fashion;
- a lamp base, which adjoins one end of the lamp vessel and, as a result, defines a lamp axis,
- a luminous element having a plurality of segments serially coupled electrically between the first power supply line and the second power supply line, the luminous element being, located within the lamp vessel and arranged essentially in an plane which is oriented perpendicularly with respect to the lamp axis, the segments being arranged in said plane around said lamp axis;
- pinches, which are formed by turned-in sections of the lamp vessel and extend essentially parallel to the lamp axis, the pinches at least partially retaining the luminous element.
