Abstract
An LED based omni-directional light engine includes a toroidal lens coupled to a controller circuit board and two or more evenly spaced LEDs mounted to the controller circuit board. The toroidal lens includes an inner surface coated with a layer of reflection materials, an outer surface, and a flat base surface. The controller circuit board is electrically coupled to a power source. The LEDs are located immediately under the flat base surface. The inner surface substantially reflects light beams emitted from the LEDs to the outer surface which refracts the beams to the omni-directions.
