FIELD: lighting.
SUBSTANCE: invention relates to a lighting device based on LED matrices. Lighting device comprises a hollow body made in the form of an axisymmetric cylinder of heat-conducting material, a light guide made in the form of an axisymmetric cylinder of optically transparent material and placed inside the hollow body coaxially with it, and the LED matrix. At the same time, one of the ends of the light guide is an outlet of the lighting device, and in the other of the ends an axisymmetric depression is made. LED matrices are placed on the outer surface of the light guide so that their radiation is reflected from the axisymmetric recess to the outlet.
EFFECT: ensuring a more even distribution of the brightness of the outlet of the lighting device.
