LAMP AND LIGHTING DEVICE WITH READJUST COLOR RENDERING INDEX Russian patent published in 2018 - IPC F21V14/00 

FIELD: lighting engineering.

SUBSTANCE: invention relates to lighting engineering. Technical result is achieved due to the fact that lighting unit (100) comprising first light source (110), second light source (210), first wavelength-converting element (1100), second wavelength-converting element (2100), is further provided with transport infrastructure (20) configured to receive a first light source, a second light source, a first wavelength-converting element and a second wavelength-converting element in a first arrangement or a second arrangement by moving one or more of them. In this case, in the first arrangement and the second arrangement, the lighting unit provides the light of the lighting unit having practically the same color point and at the same time having different color rendering indices.

EFFECT: possibility of adjusting the lighting device to allow switching between a high color rendering index with a low light efficiency and a low color rendering index with high light efficiency at a given color temperature or color point.
