COLOUR-CUSTOMIZED LIGHTING NODE, LIGHT SOURCE AND LIGHTING UNIT Russian patent published in 2017 - IPC F21V14/08 

FIELD: physics.

SUBSTANCE: colour-customized lighting node (100), a light source and a lighting unit are presented. The colour-customized lighting node (100) contains a light emitter (110), a luminescent layer (108) and a temperature controlling means (106). The light emitter (110) emits light (112) of the first colour distribution. The luminescent layer (108) receives light (112) emitted by the light emitter (110). The luminescent layer (108) comprises a luminescent material for absorbing the light portion (112) of the said first colour distribution and converting the absorbed light portions in the light (102) of the second colour distribution. The second colour distribution depends on the temperature of the luminescent layer (108). The temperature controlling means (106) actively regulates the temperature of the luminescent layer (108) to receive light emission by the colour-customized lighting node. Light emission has a specific colour distribution. The temperature controlling means (106) is configured to increase the temperature of the luminescent layer (108), to increase the average wavelength of the second colour distribution, so that the second colour distribution is shifted from the second light emission spectrum to the third light emission spectrum. The second light emission spectrum differs from the third light emission spectrum.

EFFECT: providing an improved colour-customized lighting node assembly.
