LED LAMP Russian patent published in 2022 - IPC F21V9/02 

FIELD: lighting systems.

SUBSTANCE: invention relates to lighting systems and can be used to create LED light sources close to the spectrum of sunlight, for lighting, for example, in classrooms and office premises. The declared LED luminaire contains a set of LEDs with different emission spectra, which includes two warm and two natural white LEDs, respectively, Warm White and Natural White, giving white color, with a radiation power of 5 W each and with an amplitude equal to 0.5 of the maximum power amplitude. radiation of LEDs; one Green, giving green color, with a wavelength of 520-525 nm and a radiation power of 3 W; one Yellow, giving a yellow color, with a wavelength of 590-592 nm and a radiation power of 3 W. In this case, the LEDs are selected in such a way that their emission spectra overlap each other in different parts of the total wavelength range.

EFFECT: improving the quality of the emitted light, in the spectrum approaching sunlight; reduction of the number of LEDs used in LED luminaires and the electrical power consumed by them.
