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. An exemplary application is for a streetlight head unit.
