Abstract: A plant growth lighting system includes a plant support and a light guide luminaire module, the plant support being configured to hold one or more plants. The light guide luminaire module includes at least one light-emitting element (LEE), a light guide arranged to receive light emitted by the at least one LEE at a first end of the light guide and guide the received light in a forward direction to a second end thereof, and an extractor arranged to receive light from the second end of the light guide and configured to output light. The light guide luminaire module is disposed relative to the plant support such that at least a portion of the light output by the extractor impinges on the plants in predetermined directions.

Abstract: A variety of illumination devices are disclosed that are configured to manipulate light provided by one or more light-emitting elements (LEEs). In general, embodiments of the illumination devices feature one or more optical couplers that redirect illumination from the LEEs to a reflector which then directs the light into a range of angles. In some embodiments, the illumination device includes a second reflector that reflects at least some of the light from the first reflector. In certain embodiments, the illumination device includes a light guide that guides light from the collector to the first reflector. The components of the illumination device can be configured to provide illumination devices that can provide a variety of intensity distributions. Such illumination devices can be configured to provide light for particular lighting applications, including office lighting, task lighting, cabinet lighting, garage lighting, wall wash, stack lighting, and downlighting.

Abstract: An illumination device includes a plurality of light-emitting elements (LEEs); a light guide extending in a forward direction from a first end to a second end to receive at the first end light emitted by the LEEs and to guide the received light to the second end; an optical extractor optically coupled to the second end to receive the guided light, the optical extractor including a redirecting surface to reflect a first portion of the guided light, the reflected light being output by the optical extractor in a backward angular range, and the redirecting surface having one or more transmissive portions to transmit a second portion of the guided light in the forward direction; and one or more optical elements optically coupled to the transmissive portions, the optical elements to modify the light transmitted through the transmissive portions and to output the modified light in a forward angular range.

Abstract: A solid state light sheet and method of fabricating the sheet are disclosed. In one embodiment, bare LED chips have top and bottom electrodes, where the bottom electrode is a large reflective electrode. The bottom electrodes of an array of LEDs (e.g., 500 LEDs) are bonded to an array of electrodes formed on a flexible bottom substrate. Conductive traces are formed on the bottom substrate connected to the electrodes. A transparent top substrate is then formed over the bottom substrate. Various ways to connect the LEDs in series are described along with many embodiments. In one method, the top substrate contains a conductor pattern that connects to LED electrodes and conductors on the bottom substrate.

Abstract: A solid-state luminaire module includes one or more light-emitting elements (LEEs) arranged to provide light; and a light guide including a receiving end arranged to receive the light provided by the LEEs and an opposing end, a pair of opposing side surfaces extending along a length of the light guide to guide the received light in a forward direction to the opposing end, and a redirecting end-face located at the opposing end and configured to reflect the guided light—that reaches the opposing end—back into the light guide as return light, such that substantially all the return light impinges on the pair of opposing side surfaces at incident angles larger than a critical incidence angle and transmits through the pair of opposing side surfaces into the ambient as output light of the luminaire module, the output light to propagate in backward directions.
