Summary: | Lighting device (100; 100') for illuminating tunnels, underpasses or subways, comprising: at least a first lighting (101; 101') arrangement for illuminating a lower section of a tunnel, underpass or subway and a second lighting arrangement (102; 102') for illuminating an upper section of a tunnel, underpass or subway, wherein at least one of the lighting arrangements (101, 102; 101', 102') comprises: at least one light source (220, 225; 220', 225') comprising at least one light emitting diode; at least one reflector (120, 125; 120', 125') comprising an essentially saddle-shaped reflection surface (150); wherein the light source (220) is arranged such that at least a part of the emitted light is directed to the reflection surface (150) of the reflector (120, 125; 120', 125'); and wherein the light is reflected by the reflection surface (150) in such a way that a wide light distribution of the lighting device is provided at least in a direction parallel to a surface to be illuminated and perpendicular to a main axis (160) of the reflection surface (150). |
