Abstract: A lamp assembly has a lamp reflector body adjustably mounted on a support in the form of a housing through a horizontal screw-threaded rod which engages in an internally screw-threaded element fixed to the housing. A vertical rod is mounted in the housing and terminates in an external end portion which is located so as to be easily turned manually by a spanner, socket or screwdriver. A coil spring serves to transmit drive from the vertical rod to the screw-threaded rod to adjust the reflector body relative to the housing.

Abstract: A lamp assembly has a supporting housing containing a lamp reflector body adjustably mounted therein through a mounting arrangement. The mounting arrangement includes a socket fixed to the body and an adjusting screw rotatably mounted in a sleeve of the housing and having a part-spherical end which is a snap-fit in the socket. To prevent accidental disengagement of the part-spherical end from the socket when the screw had been moved beyond a predetermined position, a member with a frusto-conical recess is slidably mounted on the screw and engages over the socket to prevent it from opening.
