Mirror type signal light e.g. back-up light for motor vehicle, has scattering elements from which light is distributed by tertiary optical component and passed through internal and cover glasses

摘要

The light emitted by a light source (1) is focused by a primary optical component (2) on a secondary optical component (3). An optical filter is positioned between secondary and tertiary optical components (3,4). The scattering elements are provided on primary and secondary optical components. The light after passing through filter is projected on a tertiary optical component. The light from scattering elements is distributed by tertiary optical component and passed through internal and cover glasses (5,6).
