Abstract
The light device of a vehicle comprises a housing (5), covered with a translucent cover (1), a light unit (4) arranged in the housing (5) comprising at least one light source, and a functional plate member (12) comprising a lamella layer (6) configured to bind light rays (10) exiting from the optical unit (4). The lamella layer (6) comprises the first lamellas (6a), which are transparent for light, and the second lamellas (6b), which are non-transparent for light, and extend across the thickness of the lamella layer (6), are in a mutual contact and alternate with each other. The first lamellas (6a) are arranged for the passage of light rays (10) and the second lamellas (6b) are configured in such a way, when the light source is off, not to reflect the daylight (DS) that falls onto the second lamellas (6b) from the said external environment out of the light device into the external environment.
