HIGH BRIGHTNESS LIGHT EMITTING DEVICE Russian patent published in 2020 - IPC F21K99/00 

FIELD: lighting.

SUBSTANCE: invention relates to a high-brightness light emitting device. Result is achieved by that device comprises high-intensity light source (102), made with possibility to emit light of first wavelength (110) to wavelength converting element (104, 300a, 300b, 300c), wherein wavelength converting element is configured to emit light of second wavelength (112) and transmission and/or reflection of light of first wavelength; and collecting lens (108), made with possibility to collect light emitted, transmitted and/or reflected from element converting wavelength. Waveform converting element comprises: wavelength converting component (302), intended for conversion of light of first wavelength into light of second wavelength, reflecting heat-conducting component (304) intended for reflection of light of second wavelength, and a beam-forming heat-conducting component 306 for transmitting light of a first wavelength and light of a second wavelength, wherein beam-forming heat-conducting component (306) is intended for directing light of first and second wavelengths with angular distribution within collecting angle of collecting lens, and wherein the wavelength converting component is in direct thermal contact with the beam-forming heat-conducting component and in thermal contact with the reflective heat-conducting component.

EFFECT: technical result is higher efficiency of heat removal from high-brightness light emitting device.
