ABSTRACT:
A light engine includes a light source disposed at a focus of four ellipsoidal reflectors, where the reflectors are arranged at 90 degrees relative to one another. A condensing lens is used with each reflector to focus forwardly directed, low angle light rays onto a target plane. Each reflector serves to reflect only the accurate, nigh angle light rays towards the target plane. Each reflector and its associated condenser produce a light beam having a reduced diameter (i.e., spot size) while also increasing the amount of optical energy directed at its respective target plane.
