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'.
