Abstract
An exterior luminaire comprising an array of light emitting diodes (2) within an outer body (12). Also within the outer body (12) is housed apparatus (7) for collecting and converting radiation into electrical energy so as to provide at least a part of the power required by the light emitting diodes (2), at least one light reflecting member (22) for reflecting light emitted by the light emitting diodes (2) out of the outer body (12), a light diffusing member (16) in the path of the reflected light, and means for maintaining the temperature around the array of light emitting diodes (2) within a predetermined range.
