Vertical illumination device with lamp modules having nano-optical lenses configured to uniformly illuminate horizontal areas below

A light emitting apparatus comprising:

• at least two non-coplanar surfaces arranged substantially vertically;
• at least two light source arrays, arranged vertically, and each coupled with one of the at least the two non-coplanar surfaces;
• each of the at least two light source arrays including a plurality of lamps;
• and
• at least two lens arrays each coupled with one of the at least two light source arrays, each of the at least two lens arrays including at least two lens-lamp combinations each comprising a plurality of nano-optical lenses,
• wherein the at least two lens array are configured to direct light from the corresponding light source array at least partly into a plurality of different sub-fields of illumination, which are substantially horizontal and disposed below the light emitting apparatus, wherein at least one of the lens-lamp combinations is configured to project light at least one of a beam angle or illumination pattern different from that of another lens-lamp combination, wherein a lamp of one of the lens-lamp combinations is mounted lower and is configured to illuminate an area within the sub-field of illumination that is nearer to the light emitting apparatus than another lamp of the light source array.

A light emitting apparatus comprising:

• at least two non-coplanar substantially vertical surfaces;
• at least two vertical light source array modules coupled to the at least the two non-coplanar substantially vertical surfaces;
• each of the at least two light source array modules 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 of the at least two lens arrays including a plurality of nano-optical lenses corresponding to each one of the plurality lamps of a corresponding light source array module,
• wherein the at least two lens array are each configured to direct light into a plurality of different sub-fields of illumination, which are substantially horizontal and disposed below the light emitting apparatus,
• wherein at least one corresponding combination of the pluralities of lamps and nano-optical lens is configured to project light at a beam angle or illumination pattern different from that of another corresponding combination of the pluralities of lamps and nano-optical lens, and an illuminated field coverage of the plurality of different sub-fields of illumination is defined according to the height and mounting location of the light emitting apparatus.
