Abstract
The oblong bulb (1) of the lamp is sealed at opposing ends by sealing pieces (6; 32), with application of a holder to each end, whereby said holder comprises an electrical contact element (13; 25), electrically connected to a power supply (15; 21), running to the lighting means. The contact element is housed in a tubular extension (11; 22) of the sealing piece and the maximum external diameter of the contact element (13; 25) is loosely matched to the inner diameter of the sleeve.
Claims11
An electric lamp sealed at two ends having an elongate bulb (1), which is sealed in a vacuum-tight manner, defines a longitudinal axis (A) and is sealed at mutually opposing ends by sealing parts (6;
- 32), in each case one base being fitted to one end, the base having an electrical contact element (13;
- 25) which is electrically conductively connected to a power supply line (15;
- 21) leading to a luminous means in the bulb, the contact element being accommodated in a sleeve (11;
- 22) and being connected to the sealing part, characterized in that the maximum outer diameter of the contact element (13;
- 25) matches the inner diameter of the sleeve, with play.
