Abstract
An LED optical assembly including an LED, a lens, and a reflector. The lens is made up of a light entry surface and a light emission surface rotated about a rotational axis. The reflector has a pair of first reflecting surfaces and a pair of second reflecting surfaces. The first reflecting surfaces are defined by a first curve rotated about the rotational axis. The second reflecting surfaces are defined by a second curve projected along the rotational axis. The lens and reflector cooperate to redirect light emitted by the LED into a vertically collimated wide angle beam of light.
