Abstract (en)
[origin: US4841421A] Housing for long-field lamps comprising interchangeable louver insert. A lock in the form of a spring arm that is secured to the face wall of the housing is suitable for the mutually releasable interlocking of the housing and louver insert in housings of long field lamps having an interchangeable louver insert. This lock has its free end projecting beyond the upper, bent-off edge of the end louver lamella when in engagement with this upper edge and being capable of being unlocked by the accessible gripping surface that is thereby formed. When such a louver is to be interchanged for a louver insert having higher louver lamellae, then, due to the upper, bent-off edge of the end louver lamellae now being higher, a refitting of the lock is required by placing it higher on the face wall of the housing. In order to avoid this, a plate-shaped lock adapter of resilient material is provided, this being secured to the backside of the end louver lamella in bent-off edge parts and, first, lengthening the gripping surface of the lock beyond the upper lamella edge and, second, representing the counter-latch for the lock at the proper height.
