Abstract
A method and apparatus for projecting a uniform projection of light by using a diffusive optic and non-imaging optic to receive light beams and uniformly distribute the light beams on a target. The uniform distribution of light diverges according to a pre-designed angle. The device allows for the use of multiple light sources which may be remotely located from the projection device. The projection device may be portable.
