Abstract
A light spreading lens, an automotive lighting system, and method of manufacturing a light spreading lens are described. The light spreading lens includes an outer surface. The outer surface is defined by a Boolean intersection of a first cylindrical lens overlaid with a second cylindrical lens. The first cylindrical lens is configured to distribute light along a first axis. The second cylindrical lens is configured to distribute light along a second axis.
Claims9
A light spreading lens comprising:
- an outer surface defined by a Boolean intersection of a first cylindrical lens configured to distribute light along a first axis overlaid with a second cylindrical lens configured to distribute light along a second axis such that the outer surface includes surface portions including shapes of the first cylindrical lens and the second cylindrical lens, wherein the outer surface is a light exit surface of the light spreading lens.
An automotive lighting system comprising:
- at least one light emitting diode (LED);
- at least one collimating structure adjacent to the at least one LED;
- and
- a light spreading structure adjacent to the at least one collimating structure, the light spreading structure comprising:
- a plurality of light spreading lenses mechanically coupled together, each light spreading lens of the plurality of light spreading lenses comprising:
- an outer surface defined by a Boolean intersection of a first cylindrical lens configured to distribute light along a first axis overlaid with a second cylindrical lens configured to distribute light along a second axis, wherein the outer surface of each of the plurality of light spreading lenses is a light exit surface for light emitted by the at least one LED.
