FOG LAMP Russian patent published in 2017 - IPC B60Q1/20 F21S8/12 F21V11/12 F21W101/10 

FIELD: physics.

SUBSTANCE: fog lamp includes a boy, a LED light source and an optical system consisting of two flat-convex lenses. The first lens is located closer to the light source and is made cylindrical. The convex surface of the second lens is directed from the light source. The LED light source contains two LEDs fixed on the same horizontally arranged straight line so that their optical axes are parallel to the optical headlamp axis and lie in the same plane A passing through the optical headlamp axis. The cylindrical surface of the first lens is directed toward the light source, and the focal line of the first lens is perpendicular to the plane A. The lenses are interconnected with their flat surfaces and bonded with optical adhesive so that a portion of the first lens is located above the plane A. The headlamp is provided with a thin plate with a through slot fixed in the inner body cavity perpendicular to the optical headlamp axis between the light source and the first lens.

EFFECT: possibility of obtaining a light beam having a horizontally located narrow strip with a distinct upper boundary and providing the road lighting below the lower limit of the strip and near the vehicle.
