    Abstract: Systems and methods for an intracanopy horticultural lighting fixture. In aspects, a horticultural luminaire has an edgelit lightguide or optical conduit extending from a housing with its major dimension extending along longitudinal axis L, and one or more endcaps coupled to respective lateral edges, endcaps being convex curved about one or more axes transverse the longitudinal axis to prevent catch points. The endcap can be coupled to the housing to hinder separation of the lightguide. In another aspect a horticultural 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 provides a method for intracanopy lighting having an entirely planar optical conduit, a major extent of the optical conduit disposed along its longitudinal axis (L), and supporting the optical conduit, preferably its entirety, below an upper plant canopy.

    Abstract: 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.

    Abstract: Embodiments may utilize a series of exposed fins, which increase the surface area of the heat sink creating additional air flow. As hotter air rises within the system, cooler is drawn into the heatsink. The fins may be exposed on both sides of the longitudinal axis, allowing cooler air to be drawn towards the longitudinal axis above the heatsink and flow upward. This process may cool the fins. Additionally, the spacing between the fins may have to be wide enough to allow for air to freely enter the heatsink.
