FIELD: electrical engineering.
SUBSTANCE: highlighting unit 12 includes light conducting elements 18. Each light conducting element 18 is configured in such a way that the maximum quantity of light is released from the light release assembly 31 area positioned closer to the front edge than the middle of the area between the light release assembly edge positioned adjacent to the light guide assembly 32 and the front edge of the light release assembly 31 when one measures the released light quantity distribution. With the help of such configuration one can additionally improve uniformity of brightness with a plane.
EFFECT: improved uniformity of brightness with a plane.
