Abstract:
1. A linear lighting apparatus, comprising: an elongated element having a substantially U-shaped cross-section comprising a first vertical sidewall, a second vertical sidewall and a horizontal floor joining the first and second sidewalls; an LED strip placed longitudinally along the horizontal floor of the elongated element; a first pair of flanges located on exterior surfaces of the first and second sidewalls, wherein the first pair of flanges is coextensive with the elongated element and coplanar with the horizontal floor; a second pair of flanges located on exterior surfaces of the first and second sidewalls, wherein the second pair of flanges is coextensive with the elongated element and parallel to the horizontal floor; a pair of gutters located on interior surfaces of the first and second sidewalls, wherein the pair of gutters is coplanar with the second pair of flanges so as to form a U-shaped protrusion on the exterior surfaces of the first and second sidewalls, thereby comprising the second pair of flanges; a first rim located on a top of the first sidewall, wherein the first rim comprises a horizontal surface adjacent to a vertical surface extending upwards from the horizontal surface; a second rim located on a top of the second sidewall, wherein the second rim comprises a horizontal surface adjacent to a vertical surface extending upwards from the horizontal surface; and a second optical element comprising an elongated planar element for placement on top of the horizontal surface of the first rim and the horizontal surface of the second rim, wherein both sides of the second optical element are adjacent to the vertical surface of the first rim and the vertical surface of the second rim.
