OPTOELECTRONIC ILLUMINATOR Russian patent published in 2011 - IPC F21K2/00 

FIELD: physics.

SUBSTANCE: device has a laser, an optoelectronic transducer, two turned reflecting mirrors and two correcting lenses. The optical output of the first turned reflecting mirror is connected to the optical input of the second turned reflecting mirror, the optical output of which is connected through the first correcting lens, the optoelectronic transducer and the second correcting lens to the optical input of the laser for pumping the laser. The optical output of the laser is connected to the optical input of a turned semitransparent mirror, the first and second optical outputs of which are connected to the optical input of the first turned reflecting mirror and the optical input of an additional optoelectronic transducer, respectively. The additional optoelectronic transducer is adapted to form a wide spectrum of visible radiation at the optical output. That output is connected to the optical input of an output objective lens.

EFFECT: illumination of large areas while preserving light power.
