FIELD: lighting.
SUBSTANCE: invention relates to optical system for focused light radiation, which can be used as full colour pixel in a raster assembly mainly for road signs of variable information and electronic display panels installed outdoors. Light source (1) operates full colour light-emitting diode in SMD structural version with red, green and blue LED chip. Directly in front of it there is input plane (3) of light guide rod (2), which completely captures light of LED chip. Light output (4) of light guide rod (2) is located in focus of convergent lens (5), which focuses outgoing light. Convergent lens (5) and light guide rod (2) can be made as a single unit. Convergent lens (5) not only focuses parallel to axis of light emitted from middle point (F), but also focuses in parallel in respective directions (p) light emitted on side of focal region (F) of points (P) output (4) of light.
EFFECT: providing light distribution in form of uniformly light, whole area in form of light output.
