Abstract A light-operated control device including a spherical housing mounted on a second housing for universal swiveling movement relative thereto. An arm extending out from the second housing overlies the sphere and is clamped thereagainst to secure the sphere in any selected position. A photocell mounted in the sphere has a light-sensitive side which faces out through an aperture in a side of the sphere. A light-channeling passage having deflector surfaces along its sides extends between the aperture and the light-sensitive side of the photocell. This passage inhibits ambient light from striking the photocell. The photocell is connected to control circuitry in the second housing by elongated flexible conductors which permit free swiveling of the sphere.
A light-operated control device comprising a substantially spherical first housing, an aperture extending through a side of said housing through which light may enter the housing, a light-responsive element mounted on said housing positioned to receive light entering the housing through said aperture, a second housing, control circuitry mounted in said second housing, mounting means mounting said first housing outwardly of a side of said second housing for universal swiveling movement relative to said second housing between multiple adjusted positions with the light-responsive element facing in different directions in said adjusted positions, said mounting means including means defining a seat on said side of said second housing receiving a side portion of said first housing, and an arm mounted on and projecting outwardly from the second housing having an engaging portion forming a seat which receives another side portion of the first housing which other side portion is diametrically opposite the first-mentioned side portion of the first housing, said light-responsive element facing to one side of said first-mentioned and other side portions of the first housing, adjustable means for releasably clamping said seats against said first housing frictionally to secure the first housing relative to said second housing in a selected adjusted position, and means electrically interconnecting said light-responsive element and said control circuitry and accommodating such universal swiveling movement of the first housing relative to the second housing.
