LIGHT EMITTING ASSEMBLY, LAMP AND LIGHTING DEVICE Russian patent published in 2018 - IPC H05B33/14 H01L33/00 

FIELD: lighting engineering.

SUBSTANCE: invention relates to lighting engineering. Light emitting assembly 100 comprises first light source 112, second light source 118, first luminescent material 106, second luminescent material 116 and light outlet window 102. First light source 112 emits light 110 in the ultraviolet spectral range. Second light source 118 emits light in the blue spectral range having the first peak wavelength. First luminescent material 106 is configured to receive light 110 from first light source 112 and is configured to absorb light 110 in the ultraviolet spectral range and to convert part of the absorbed light into light 104 in the blue spectral range. Second luminescent material 116 is configured to receive light 105 from second light source 118 and is configured for almost complete conversion of received light 105 in the blue spectral range received from the second light source into light with a spectral range of light having the second peak wavelength. Second peak wavelength is greater than the first peak wavelength. Light outlet window 102 is configured to transmit the light emitted by first luminescent material 106 and by second luminescent material 116 into the environment from light emitting assembly 100.

EFFECT: simplification of the technology of manufacturing the assembly emitting light.
