Linear lighting system

摘要

Embodiments of the invention are directed toward a lighting system that includes a primary optic having a length, a plurality of discrete light sources disposed along an axis, and a ribbed refractor. The ribbed refractor can include a plurality of linear ribs that are arranged substantially perpendicular to the line of discrete light sources. The ribbed refractor can refract light from the plurality of discrete light sources into a continuous line of light as viewed along the length of the primary optic, thereby masking the discrete nature of the light sources. In some embodiments, the ribbed refractor does not substantially alter the photometric distribution of light perpendicular to the axis.

主权项

1. A light fixture comprising:
a plurality of LEDs spaced along an axis, adjacent ones of the LEDs being spaced at a first distance from one another; a ribbed optical element configured to receive and disperse the light from the plurality of LEDs into a continuous line of light parallel to the axis, without substantially altering a photometric distribution of the light in a direction perpendicular to the axis, the ribbed optical element comprising an optically clear material with a plurality of ribs disposed on a surface thereof and extending perpendicular to the axis; adjacent ones of the ribs being disposed on the surface at a pitch that is less than the first distance.
