Abstract
A lens for a light fixture has a plurality of protrusions for spreading a beam of light from a light source of the light fixture. The protrusions enable the lens to be used in different light fixtures while providing similar beam characteristics. In some configurations, the lens comprises texturing to further shape the beam.
Claims20
A system for a light fixture comprising:
- a reflector arranged to reflect a portion of light from a plurality of light sources to a lens;
- and
- the lens comprising:
- an optical surface;
- and
- a plurality of protrusions extending from the optical surface of the lens, the plurality of protrusions each defined by a base and an apex, wherein:
- the apex is rounded;
- at least a portion of a wall of the protrusion, between the base and the apex, is straight;
- the plurality of protrusions are cones;
- the portion of the wall of the protrusion that is straight is a slant of the cone;
- each cone has a half angle equal to or greater than 30 degrees and/or equal to or less than 87 degrees;
- and
- the portion of the wall that is straight is arranged to receive light from at least a subset of the plurality of light sources.
10 more elements
A method comprising:
- generating light from a plurality of light sources;
- transmitting light from the plurality of light sources towards a lens, wherein at least a portion of light from the plurality of light sources is reflected by a reflector to direct light towards the lens;
- and
- transmitting light through the lens, wherein:
- the lens comprises a plurality of protrusions extending from an optical surface of the lens, the plurality of protrusions each defined by a base and an apex,
- the apex is rounded;
- at least a portion of a wall of the protrusion, between the base and the apex, is straight;
- the wall that is straight creates a half angle in relation to the apex equal to or greater than 30 degrees and/or equal to or less than 87 degrees;
- and
- the portion of the wall that is straight is arranged to receive light from at least a subset of the plurality of light sources.

A lens comprising:
- an optical surface;
- and
- a plurality of protrusions extending from the optical surface of the lens, the plurality of protrusions each defined by a base and an apex, wherein:
- the apex is rounded;
- and
- at least a portion of a wall of the protrusion, between the base and the apex, is straight;
- a half angle, measured from the portion of the wall that is straight and in relation to the apex, of the plurality of protrusions varies as a function of distance from a center of the lens;
- and
- the portion of the wall that is straight is arranged to receive light from at least a subset of a plurality of light sources.
