FIELD: physics, optics.
SUBSTANCE: invention relates to an illumination device. The device comprises a light source and a lens placed in front of the light source. The lens is provided with a light input surface on the side facing the light source and a light output surface on the side away from the light source. The lens includes a certain number of strip elongated light guide elements connected to each other near the second ends and has light input surface and a light output surface. Light beams emitted by the light source are transmitted to the elongated light guide elements through total internal reflection.
EFFECT: lower detectable brightness owing to a larger light output surface compared to the light emitting surface.
