FIELD: electric engineering.
SUBSTANCE: invention relates to lighting device (10) with radiator (1) of light, which comprises concentric rings and/or sectors of organic light diodes (OLEDs), of at least two different main colours. Downstream the light radiator (1) there is the primary optical system, for instance collimator (13) or lens and narrowing tubular reflector (14), diametre (d) of which increases from its narrow end to its wide end. Light radiator (1) may, in particular consist of concentric rings of different OLEDs.
EFFECT: improved homogeneity of light distribution by application of light radiator in the form of concentric rings and sectors of organic light diodes of different main colours, and due to narrowing tubular reflector, with various form of section.
