Abstract
Abstract A wall light fixture, particularly for hospital rooms or sickrooms, in which a room light fixture and a reading light fixture are connected, and can be tilted from a room lighting position to a reading position, and vice versa. The reading light fixture with its housing is seated in a carrier to be attached to the wall of a room. The room light fixture mounted in this carrier or on the housing of the reading light fixture, can be tilted from the room lighting position to the reading position. The position of the room and reading light fixture relative to each other is adjustable, and the housing of the reading light fixture has a recess or chamber into which the room light fixture with its housing can fit. The housings of the room and reading light fixture are connected by a hinge or joint extending over the length of the light fixture. Stops may be applied to restrict the relative adjustment of the two light fixtures.
