Abstract:
1. A lamp and reflector unit comprising: a lamp vessel comprising a wall enclosing in a gastight manner a space having a light emitting element arranged therein, and comprising electrical current conductors which extend from the light emitting element through the wall to the exterior; a reflector having a reflecting portion extending between a neck opening formed in a neck and a light emission window of the reflector, the reflecting portion defining an optical axis, the lamp vessel being arranged in the reflector such that the optical axis extends through the light emitting element; a lamp cap fixed to the lamp and reflector unit proximate to the neck opening, the lamp cap comprising electrical contacts, each electrical contact being electrically connected with a respective electric current conductor, the electrical contacts being provided substantially opposite to each other on an outer surface of the lamp cap, wherein said lamp cap has a substantially identical first and second mating part, each of said first and second mating part having a pair of grooves; said electrical current conductors being a first spring clamp and a second spring clamp, each of said spring clamps having hook-shaped ends which grip into said pair of grooves formed in said mating parts; wherein said first and second spring clamps at least partially retaining said first and said second mating parts of said lamp cap together; each of said first and said second mating part further having an inner surface having a protrusion, said protrusion seating in first and second indentations formed in respective indentations formed in said neck of said reflector; said first and said second mating parts further having interlocking teeth on facing walls which interlock and overlap to securely close a combined wall of a cavity formed by said first and said second mating parts.
