A lamp system comprises a light source and a parabolic reflecting collar positioned around the light source and having an aperture through which a center axis extends. The aperture permits light rays emitted by the light source at low angles relative to the axis to be emitted from the parabolic reflecting collar, while light rays emitted by said light source at higher angles are reflected by the collar for recycling. The parabolic reflecting collar is positioned such that higher angle light rays are reflected twice, off opposing wall reflecting portions, back to their point of origin. Preferably the light source is an array of multiple LEDs having different colors and sizes. |
