Patent ID: 10393341

Abstract:
A tri-lobe optic for a linear light source, and related light rails, retrofit kits and light fixtures, are disclosed. The linear light source defines a light emitting region along an axis. The tri-lobe optic includes an optical material having a constant cross-sectional profile along a direction of the axis from a first axial end to a second axial end. The cross-sectional profile includes a first azimuthal side relative to the axis and concave and convex curves relative to the axis. The curves are a first concave curve coupled with the first azimuthal side, a first convex curve, a second concave curve, a second convex curve and a third concave curve. Each of the concave curves defines a lobe of the optical material along the direction of the axis. The cross-sectional profile further includes a second azimuthal side relative to the axis, coupled with the third concave curve.
