US Patent 11029000 Horticultural luminaire having endcap with receiving sockets

Systems and methods for an intracanopy horticultural lighting fixture. In aspects, a horticultural luminaire has an edgelit lightguide or optical conduit (40) extending from a housing, a lightguide length extending along longitudinal axis L, and one or more endcaps (214) coupled to respective lateral edges extending along a height axis H, the endcap having a lightguide-receiving socket spaced (220) adjacent a lightsource housing-receiving socket (218). In other aspects the endcaps are convex curved about one or more axes transverse the longitudinal axis to prevent catch points. In another aspect a luminaire has an edgelit lightguide generating an output having downwardly directed peaks at about +/−30 degrees from vertical. Light output is preferably batwing shaped and symmetric. Another aspect is providing intracanopy lighting having a planar optical conduit, a major extent of which is disposed along its longitudinal axis (L), and supporting the optical conduit below an upper plant canopy.
