DIMABLE LIGHT EMITTING ARRANGEMENT Russian patent published in 2018 - IPC H05B33/08 

FIELD: instrument engineering.

SUBSTANCE: invention relates to a light-emitting arrangement with an adjustable light intensity. Result is achieved by the fact that light-emitting arrangement (100) with adjustable light intensity comprises first light source (10), second light source (20) being arranged to emit light of a first wavelength band between 380 and 460 nm, first wavelength conversion material (30) and second wavelength conversion material (40) being arranged to emit light of a second wavelength range between 570 and 610 nm. First wavelength conversion material (30) receives light from first light source (10) and converts the light of the first wavelength range into light, having a radiation peak within the third wavelength range between 470 and 570 nm. Second material (40) for converting the wavelength takes light from the first and second light sources and converts the light of the first wavelength range and the light of the second wavelength range into light, having a radiation peak within the fourth wavelength range between 590 and 630 nm.

EFFECT: technical result is to provide a light-emitting arrangement with an adjustable light intensity having a relatively low correlated color temperature in a dimmed state and a relatively high and constant color rendering index.
