Reflector adjusting system for lamp with rotation symmetrical reflector - has fixed holder for lamp arranged in reflector housing and reflector is arranged adjustable in this by relative movement between lamp and reflector.

摘要

The reflector (13) is adjustable in an axial direction (19). A adjusting unit is assigned to the reflector. The adjusting unit consists of a rotational ring located at the reflector housing (4). The ring extends in a circumferential direction, it has a rising gradient surface radial, to which guide elements are assigned. These guide elements are designed as pins (22) at the circumference of a locking ring (20), and lying on the sloping surfaces (29,39) of the rotational ring (25). The locking ring is connected with the reflector (13), and is located rotationally proof and movable in the adjusting direction in the reflector housing (4). ADVANTAGES - During entire operation of lamp, reflector can be easily adjusted by hand without operating fixing means. Adjusting system can be produced simply and cost effectively.
