LAMP Russian patent published in 2021 - IPC F21V9/00 A01G9/20 

FIELD: lighting.

SUBSTANCE: invention relates to lighting devices that provide illumination with light that maximally corresponds to the spectrum of sunlight due to the use of light-emitting diodes. The lamp contains a set of LEDs with different radiation spectra, lying in the wavelength range of the photosynthetically active part of the solar spectrum of the order of 390-740 nm, equipped with power drivers. LEDs with emission spectra in the range of 390-740 nm are used. The spectra of the LEDs used overlap each other in different spectral parts of the range, preferably at the level of 0.1-0.8 of the maximum amplitude at the central wavelength of the radiation. Six types of LEDs of different spectrum with a power from 0.1 to 500 W are used. The emitted spectrum includes the emission spectra of LEDs such as White, Ultraviolet, Blue, Red, Infrared, and Plant light. The drivers of these LEDs are made with the possibility of supplying power of such a magnitude that the level of luminous flux from the corresponding LEDs is equal to 1; 0.21; 0.83; 0.09; 0.71 of the level of the luminous flux emitted by the Plant light LED. The spectrum type is formed by a set of the one-type LEDs with the ability to generate a luminous flux power that is the same for each individual spectrum type. These LEDs have the maximum radiation at the wavelengths, respectively, 583, 403, 490, 630, 737 and 647 nm.

EFFECT: use of the invention will make it possible to provide a lamp consisting of LEDs of six different types of radiation, with the radiation spectrum closest to sunlight.
