Spherical light output LED lens and heat sink stem system
First Claim
1. A lens attachable to an LED light source comprising:
- a body includesa vertical central axis running along the height of the lens;
a lens as the crown of the lens;
5 pointed, reflective and refractive elements, which totally internally reflect light and then refract light emitted from the LED light source such that the majority of the light rays emitted from the lens is radiated around a 300 degree angle in the vertical plane and 360 degrees in the horizontal plane;
an internal surface within the lens roughly parallel to an LED light source which acts as a lens, directing more light towards the pointed elements or towards the crown of the lens.an attachment means for coupling the lens to an LED holder or heat sink stem;
a base surface for coupling to a light source.

Abstract
This light emitting 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; 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.
