The lighting system which possesses with the cap equipped light bulb which is combined to the cap equipped light bulb, and the reflector and the said reflector

摘要

The cap (10) of the capped electric lamp (1) has a resilient member (14) which acts transversely to the axis (10') of the cap. This allows the lamp to be used in a lighting system having the lamp and a reflector (40), in which the reflector is of a simple construction. The resilient member (14) presses transverse reference locations (13) of the cap against flat mounting surfaces (50) in the reflector, which are located on the legs of a V. The cap (10), and thus the electric element (3) inside the lamp vessel (2), are as a result accurately positioned in the reflector in two directions transverse to the axis. The cap (10) may in addition have projections (23,24,25) distributed over its circumference, each having an axial reference location (12), by which the cap is axially aligned in the reflector (40) through cooperation with surfaces (49) ridge portions (46,47,48) of the reflector.
