Abstract
Disclosed is an illumination device for projecting a substantially uniform light at a remote distance. The illumination device comprises a mounting assembly divided into a plurality of sections, each section comprising a plurality of light emitting sources arranged substantially equidistant along a circumference of the assembly to project a light substantially perpendicular to the assembly, an contact plate connected via a central axis with, and fixed to, the mounting assembly, the contact plate providing an electrical contact to each of the light emitting devices, a plurality of lensing assemblies equal in number to the plurality of sections axially aligned with the mounting assembly, the lensing assembly aligned with a select one of the light emitting sources in a corresponding section, the light emitting source being positioned in front of a focal point of the lensing assembly, each lensing assembly comprising at least one optically transparent lens determining the lensing assembly focal point wherein the lensing assembly is oriented at a known angle with regard to the light projected from the light source, and means for shifting the contact plate and mounting assembly to align …
