Abstract
An illumination device includes a support section, a heatsink coupled above the support section and including a plurality of flat vertical exterior surfaces, a driver housing coupled above the heat sink, a plurality of light source modules coupled to the exterior surfaces of the heatsink, and a plurality of nano-optical lenses coupled to the light source modules to direct light from the light source modules to sub-fields of illumination disposed horizontally below. The illumination device is mounted above ground and configured for uniformly illuminating the sub-fields of illuminations without direct glare.
Claims19
A light-emitting apparatus comprising:
- a heatsink having an air ingress opening, an air evacuation opening, an interior channel defined between the air ingress and evacuation openings, and at least two exterior vertical flat surfaces, the heat sink configured to allow air flowing in through the air ingress opening, though the interior channel and out the evacuation opening;
- at least two light source array modules coupled to the exterior flat surfaces in a preconfigured orientation, each light source array including a plurality of lamps;
- and
- at least two lens arrays each coupled to one of the at least two light source array modules, each lens array including a plurality of nano-optical lenses corresponding to each of the lamps in a corresponding light source array;
- wherein the at least two lens arrays are configured to direct light from each light source array module into a plurality of different sub-fields of illumination which are substantially horizontal and disposed below the light-emitting apparatus, and at least one lamp and nano-optical lens combination is configured to project light at a beam angle or illumination pattern different from that of another lamp and nano-optical lens combination.

A light-emitting apparatus comprising:
- a heatsink including a plurality of exterior vertical flat surfaces;
- a plurality of light source array modules coupled with the exterior flat surfaces of the heatsink in a preconfigured orientation, each light source array module including a plurality of lamps;
- and
- a lens cover positioned over each light source array module, each lens cover including a plurality of nano-optical lenses corresponding to the lamps,
- wherein:
- center beams of at least two light source array modules of the plurality of light source array modules are directed by the lens cover to target different sub-areas within a same or different sub-field of illumination,
