Abstract:
1. A light sign for displaying an instruction and/or guidance for taxiing airplane traffic at an airport, comprising: a casing with a translucent display panel for representing an instruction and/or guidance symbol, a light source arranged inside the casing with at least one luminescent diode for illuminating the display panel, and a diffusion panel, which is configured for scattering and/or back-scattering of incident light, wherein the light source is arranged between the display panel and the diffusion panel, wherein the light source is positioned at a distance from the diffusion panel such that reflected light is substantially similar to a value of background lighting, wherein the light source is positioned at a distance from the display panel to reduce a shadow from the light source on the display panel, wherein the at least one luminescent diode is aligned on the diffusion panel in such a way that the display panel is not directly but indirectly illuminated by the at least one luminescent diode by back-scattering of the light emitted from the at least one luminescent diode by the diffusion panel.
