Spherical Light Output LED Lens and Heat Sink Stem System

Abstract

This light emitting diode (LED device provides a 360 degree lighting angle in the horizontal plane and a 300 degree lighting angle in the vertical plane while simultaneously addressing LED die thermal management, which is critical to high lumen output LEDs. This LED lighting device is comprised of the LED lens, the LED holder and the heat sink stem. Light produced by at least one LED die traveling vertically is diffused by the top refractive portion of the lens. Light rays directed towards the pointed elements are totally internally reflected downwards then refracted out of the lens, thus resulting in a spherical light pattern. This technology is designed as a replacement for conventional light sources, such as incandescent light bulbs, halogen bulbs, CFLs (compact fluorescent lamps) and metal halide lamps.
