FIELD: electricity.
SUBSTANCE: lighting device (100) contains one or more first lighting diodes (202) for formation of the first emission spectrum (503) and one or more second lighting diodes (204) for formation of the second different emission spectrum (505). The first and second light emitting diodes (LEDs) are connected electrically between the first unit (516A) and the second unit (516B) where sequence current (550) flows with feed of operating voltage (516) to the unit. Controlled path (518) of current flow is connected in parallel to one or both first and second LEDs in order to drain sequence current at least partially so that the first current (552) through first LED(s) and the second current (554) through LED(s) have different values. These technologies for current draining can be used to compensate offset of colour or colour temperature of formed light during heat transfer processes in result of different temperature-dependent current to flow ratios for different types of LEDs.
EFFECT: improving the efficiency.
