ABSTRACT:
A versatile outdoor lighting and/or display assembly provides for maximal positional adjustability of individual fixtures and permits the size and directivity of the light-emitting openings of the fixtures to be selectively changed. In one embodiment the assembly includes two linear reflected lighting fixtures mounted with their axes in fixed spaced parallel relation, each of the fixtures being independently rotatable through a complete 360.degree. range. In a second embodiment, a first linear reflected lighting fixture is mounted on a second linear reflected lighting fixture such that the first fixture is selectively rotatable about three mutual transverse axes and is selectively translatable along the length dimension of the second fixture. The light-emitting openings of the fixtures can be varied in size and directivity by means of deflectors mounted along the longitudinal edges of the fixture reflector, the deflectors being oriented to diverge at angles appropriate to achieve the desired size of the enlarged light-emitting opening.
