Optical unit for electrical lighting apparatus, has lens for allowing passage of polychromatic light flux from one side to another side of lens, and homogenizing unit arranged for mixing flow of color spectrum light flux
The optical unit (1) has a lens (4) for allowing passage of polychromatic light flux from one side (5) to another side (6) of the lens. A homogenizing unit (7) is arranged for mixing the flow of color spectrum light flux. The homogenizing unit includes a planar surface (8) with microcavities, where the microcavities are micro-spheres and/or micro-prisms. The micro-spheres are arranged in a plane parallel to a plane surface of the latter side of the lens, where the micro-spheres are coupled with each other. Independent claims are also included for the following: (1) an electric lighting apparatus (2) an assembly of an electric lighting apparatus and a recessed housing.
