Systems and methods for a high output, high color quality light are disclosed. In some embodiments, such a light may include a light fixture including one or more LEDs configured to output a cumulative light output; wherein the cumulative light output comprises an intensity of greater than or equal to 10,000 lumens; and wherein the cumulative light output comprises a CRI of at least 90.

Systems and methods for high output, high color quality light

In one aspect, luminaires are described herein having sensor modules integrated therein. In one aspect, a luminaire described herein comprises a light emitting face including a LED assembly. A sensor module is integrated into the luminaire at a position at least partially overlapping the light emitting face. In another aspect, a luminaire described herein comprises a LED assembly and a driver assembly. A sensor module is integrated into the luminaire along or more convective air current pathways cooling the LED assembly or driver assembly.

LED luminaire having enhanced thermal management

A luminaire has a light emitting portion extending between first second end caps to define a length between the first end cap and the second end cap. The first end cap comprises a receptacle and the second end cap comprises a post both of which extend in an insertion direction. The receptacles are configured to closely receive the posts and the insertion direction is disposed transversely to the length. A method of assembling a luminaire assembly includes positioning a first end cap of a first luminaire over a second end cap of a second luminaire; moving the first end cap relative to the second end cap in the insertion direction; and inserting the post into the receptacle. An electrical connector on the first end cap may connect with a mating electrical connector on the second end cap to complete an electrical connection between the first luminaire and the second luminaire.

Luminaire and connection mechanism for connecting multiple luminaires

According to an aspect of the present disclosure, a waveguide comprises a waveguide body comprising an optically transmissive material and one or more extraction features disposed on a surface of the waveguide body such that the extraction features comprise a reflective material disposed on a portion of the surface of the waveguide body. Still further, in accordance with this aspect, the waveguide comprises a light source directing light into the waveguide body through a coupling cavity extending along the waveguide body wherein the light travels through the waveguide body and is redirected by the plurality of extraction features.

Optical waveguides and luminaires having a waveguide with extraction features and reflective material having openings disposed thereon

In one aspect, luminaires are described herein enabling independent thermal management of driver and LED assemblies. For example, a luminaire comprises a driver assembly vertically integrated with a LED assembly, the driver assembly comprising a driver heatsink having an interior in which a circuit board assembly is positioned, and the LED assembly comprising an array of LEDs and LED heatsink, wherein a barrier is positioned between the driver heatsink and the LED heatsink, separating convective cooling of the driver assembly from convective cooling of the LED assembly.

In one aspect, optic assemblies and waveguide fixtures comprising the same are described herein. In an exemplary embodiment, an optic assembly includes an optic housing, an optical insert positioned in the optic housing, and a waveguide optic positioned in the optical insert. The waveguide optic includes a light extraction face and at least two sets of light extraction elements provided on the light extraction face. The at least two sets of light extraction elements are disposed on opposing sides of an axis of symmetry for extracting a symmetric lighting distribution.

Lighting apparatus

Assume that the two groups of lighting fixtures are located in the same general area, employ daylighting, and provide light that can be sensed by each other. A first group will determine an actual lighting contribution provided by the second group and remove the actual lighting contribution provided by the second group when making daylighting decisions. As such, when the dimming level of the second group is changed, the first group will effectively ignore changes in the dimming level of the second group when making daylighting decisions, and vice versa. A group of lighting fixtures may include one or more lighting fixtures.
