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.

[ We claim:] [1.] A device for projecting a uniform distribution of light comprising:at least one light source for producing a light beam;a diffusive optic, said diffusive optic having an input aperture and an output aperture, wherein said diffusive optic is positioned to receive said light beam at said input aperture and produce a Lambertian flux at said output aperture;transmitting means for transmitting said light beam from said light source to said diffusive optic; and,a non-imaging optic, said non-imaging optic having an entrance and an exit wherein said entrance is positioned to receive said Lambertian flux light output from said output aperture, and wherein said exit outputs said Lambertian flux as a uniform distribution of light.
