FIELD: physics.
SUBSTANCE: traffic light optical system comprises a Fresnel lens (13) with Fresnel structures (15) on the inner light input surface. The outer light output surface (16) is made such that each tangent (17) to the outer light output surface (16) forms an angle ≥105° with respect to the optical axis (14) of the optical system.
EFFECT: suppression of the phantom effect.
