Title: Airport taxi signal light having LED light array with light processing assembly and dichroic filter

Abstract: A signal light including a housing is recessed into a traffic surface and projects minimally upwardly from the surface and wherein a light processing assembly is provided to receive light from a light source, intensify the light and direct the light toward a light outlet in a generally linear manner, the arrangement for processing light being mounted to the housing. For this purpose, the light source is designed in such a way that it sends an essentially linearly directed light beam onto the light processing assembly. The light is collected in the light processing assembly in such a way that, when it exits, it is still linearly extending in at least one direction but it has a higher intensity. For this purpose, the light processing assembly includes a cylindrical-convex lens entry surface and a cylindrical concave mirror surface for receiving and directing light.
