Patent ID: 7021796

Claim:
A light engine for generating a high intensity, narrowly focused optical output signal, the light engine comprising: a light source for generating an optical input signal; a refractive optical focusing element disposed so as to receive a first portion of said optical input signal and to focus said first portion into a first output signal component that is directed at a target; a reflector forming a housing to house said refractive optical focusing element, and arranged adjacent said light source to reflect a second portion said optical input signal that does not illuminate said optical focusing element towards said target, said second portion forming a second output signal component; wherein said reflector houses said light source, and includes a plurality of four of ellipsoidal reflectors formed in said housing and arranged at 90° angles to one another; and wherein said refractive optical focusing element and said reflector cooperatively operate to focus said first and second output signal components to an approximately common spot size, such that said first and second output signal components substantially overlap one another at a desired target plane to form a unified, focused optical output signal focused on said target.
