ABSTRACT:
A light engine including a lamp casing having a tubular light pipe receptacle. A large core optic light pipe extends from outside the light engine into the tubular receptacle. The light pipe has an inner end supported in the tubular receptacle. Two half-ellipsoidal reflector dishes are joined to form a single ellipsoidal reflector within the casing. A lamp is supported within the casing adjacent a first focal point of the ellipsoidal reflector. The reflector is positioned to focus light energy from the lamp onto a second focal point of the ellipsoidal reflector. A quartz thermal barrier is disposed in the tubular receptacle between the lamp and the light pipe inner end. The thermal barrier has an outer end surface optically coupled to the light pipe and an inner end surface disposed adjacent the second focal point of the reflector to receive convergent light emitted from the lamp and reflected from the reflector.
