Abstract: 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.

Abstract: 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.
