FIELD: electrical engineering.
SUBSTANCE: lightguide contains a covering layer and a lightguide plate having a top and a bottom surface and containing surface relief elements passing within the said lightguide plate. The covering layer and the lightguide plate are designed to that to enable conductance of light, the covering layer positioned close to the surface relief elements so that cavities are formed between the covering layer and the lightguide plate. In the crosswise side section, each surface relief element is symmetrical relative to an axis perpendicular to the covering layer flat surface. The lightguide plate thickness exceeds that of the covering layer.
EFFECT: higher efficiency of highlighting.
