FIELD: lighting engineering.
SUBSTANCE: invention relates to a spectral-selective radiation source. Radiation source has a hollow body made in the form of a truncated cone with a window-lens in a small base for radiation output. Along axis of cone there is reflector in form of conical pyramid. Inside the cone there is a light-emitting multichannel structure, made in the form of hollow channels-sections, each of which consists of section of internal surface of cone with luminescent layer, and section of reflector in form of surface concave to axis of cone. Two LEDs are installed in each channel-section. First light-emitting diode is installed in the housing wall near the large base of the cone and is intended for excitation of luminescence. Second one is located in the large base and is a complementary light-emitting diode.
EFFECT: technical result consists in wider spectral range, high efficiency of photon transforms and enabling control of spectral characteristics.
