The signal light of mirror type consists of a light source (1), a primary optical component (2), a secondary optical component (3), a tertiary optical component (4), one or more internal glasses (5), a cover glass (6) and an optical filter (7), characterized in that the light put out by the light source (1) is focused by the primary optical component (2) on the secondary optical component (3), and scattering elements, which are on the primary optical component (2) or on the secondary optical component (3) or on the primary optical component (2) and the secondary optical component (3), after passing through the optical filter (7) are projected onto the tertiary optical component (4), while the tertiary optical component (4) is formed by one or more smooth surfaces of a mirror type, and the image of the scattering elements is further distributed by the tertiary optical component (4) and passes through the one or more internal glasses (5) and the cover glass (6). |
