Abstract
A light system includes a housing and a lighting assembly. The housing includes a first cap, a second cap, and a lens arranged between the first cap and the second cap to form a periphery of the housing. The lighting assembly is arranged proximate to the first cap and includes a plurality of lighting elements configured to emit light toward the second cap. The lens includes a waveguide having a reflecting surface that is non-planar and that is configured to receive the light emitted by the plurality of lighting elements and direct the light toward the periphery of the housing.
Claims20
A light system, comprising:
- a housing including:
- a first cap;
- a second cap arranged in opposition to the first cap;
- and
- a lens arranged between the first cap and the second cap to form a periphery of the housing;
- and
- a lighting assembly arranged proximate to the first cap and including a plurality of lighting elements configured to emit light toward the second cap,
- wherein the lens includes a waveguide having a reflecting surface that is non-planar and that is configured to receive the light emitted by the plurality of lighting elements and to direct the light toward the periphery of the housing via total internal reflection, the reflecting surface including a plurality of elongate depressions that each extend along the waveguide to define rows that are parallel with the periphery.
A light system, comprising:
- a housing including:
- a first cap;
- a second cap arranged in opposition to the first cap;
- and
- a lens arranged between the first cap and the second cap to form a periphery of the housing, the lens including a waveguide having a first lens element extending along a first portion of the periphery and a second lens element extending along a second portion of the periphery;
- and
- a lighting assembly arranged proximate to the first cap and including a plurality of lighting elements configured to emit light,
- wherein the waveguide is configured to receive the light emitted by the plurality of lighting elements and includes a plurality of elongate concave depressions that direct light toward the periphery of the housing via total internal reflection, each of the plurality of elongate depressions extending along the waveguide in parallel rows to direct the light toward the periphery of the housing.
A light system, comprising:
- a housing including:
- a first cap;
- a second cap arranged in opposition to the first cap;
- and
- a lens arranged between the first cap and the second cap to form a periphery of the housing;
- and
- a lighting assembly including a plurality of lighting elements configured to emit light toward the lens,
- wherein the lens includes a prismatic waveguide having a first surface configured to collect the light from the plurality of lighting elements and a second surface defining a plurality of elongate depressions that each extend along the waveguide to define rows parallel to the periphery to receive and transversely direct the light via total internal reflection to a third surface that defines the periphery.
