Abstract

A lamp projecting a high-intensity optical beam of spectral radiation, with an IR-extracting (cooling) array including an IR-dissipating "black-box" arranged to receive IR and convert it to box-heat, plus an IR-diverting "hot-mirror" interposed along the beam to divert (only) the IR to this "black-box".
