Abstract: An exemplary embodiment of a light system includes a plurality of elongated light modules each comprising a plurality of separate light emitting diodes (LEDs), at least one adjustable length bracket structure configured to fix each LED module in position within the box light housing, each bracket structure comprising a first, module engaging end for engaging an end of the LED module, a second, support wall engaging end for engaging against a wall of the box light housing structure, and a length adjustment mechanism for adjusting the distance between the first bracket end and the second bracket end. In an exemplary embodiment, the length adjustment mechanism includes a turnbuckle mechanism.

Abstract: An exemplary embodiment of a light head includes a housing structure, a light source, and a lens or transparent window through which light emitted by the head light source is passed. The head further includes an electrical module, and a plurality of separate light emitting diode (LED) modules as the light source, connected to the electrical module to provide electrical power to the LED modules. The LED modules are supported in the housing structure by a bracket system, which also permits angular adjustment of an interior pair of the modules to adjust an illumination pattern of the light head. An exemplary application is for a streetlight head unit.
