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.
