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: 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.

Abstract: 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.
Abstract translation: 假设两组照明装置位于相同的一般区域，采用采光，并提供彼此可以感测的光。 第一组将确定第二组提供的实际照明贡献，并在作出采光决定时，删除第二组提供的实际照明贡献。 因此，当第二组的调光水平改变时，第一组将在进行采光决定时有效地忽略第二组的调光水平的变化，反之亦然。 一组照明装置可以包括一个或多个照明装置。
