Abstract:
An optical output system for an LED light source has a pair of lens arrays (40, 42) with a narrow air gap (48) between the lens arrays (40, 42). The optical system provides an optical integration function for light mixing, and the air gap (48) enables a uniform wide-beam output to be provided even for incident light from a wide range of angles, for example as received from a non-collimated light source.
