Abstract: A light fixture having a base coupled to a housing by means of a coupling of the ball and socket type. The light housing may be fixed in any angular orientation over a range of azimuth angles well in excess of two hundred and seventy degrees and any angle of elevation from completely horizontal to completely vertical. The coupling can do so while accommodating the passage of electrical conductors from the base of the fixture extending toward the lamp and while also protecting the fixture against misuse in the form of repeated rotation tending to disconnect those conductors internally of the fixture. Altering the relative positions of a lamp and reflector changes the width of the beam cast by the apparatus. With the reflector and front lens fixed, a lamp holder is mounted for sliding motion with respect to the rear of the housing and is moved by manual actuation of a mechanism accessible from the rear of the fixture.

Abstract: The reflector of the spotlight has two assembly lugs directly fitted thereto and connected to an intermediate assembly part which includes means for fixing to a support. Said intermediate assembly part and said lugs are shaped to ensure that two mutually perpendicular planes defined relative to said reflector coincide with corresponding ones of two mutually perpendicular planes defined relative to said intermediate assembly part, regardless of relative thermal expansions which may take place in the reflector and the intermediate part under normal conditions of use. Relative to the reflector said planes comprise a first plane including the optical axis and a second plane perpendicular to said first plane and parallel to the optical axis. Such an assembly reduces the effect of thermal expansion on the adjustment of the direction in which the optical axis points.
