Abstract
A rail lighting fixture for providing illumination along a rail of a railway track includes a housing arranged for attachment to the rail and provided with at least one aperture. At least one light source is provided in the housing and arranged to emit a light beam. The lighting fixture is arranged to direct the light beam through the aperture towards a lighting direction, and the lighting direction has a component that is parallel to a longitudinal direction of the rail.
Claims21
A rail lighting fixture for providing illumination along a rail of a railway track, wherein the lighting fixture comprises a housing, arranged for attachment to the rail and provided with at least one aperture, and at least one light source provided in the housing and arranged to emit a light beam, wherein the lighting fixture is arranged to direct the light beam through the aperture towards a lighting direction, wherein the lighting direction has a component that is parallel to a longitudinal direction of the rail, wherein:
- the aperture is provided with an optical element arranged to receive the light beam and to direct the light beam towards diverging directions;
- or
- the aperture has an optical axis extending, as seen in the horizontal plane, at an acute angle with the longitudinal direction and away from the rail as seen along the lighting direction.
A rail lighting system for providing illumination along a rail of a railway track, wherein the rail lighting system comprises at least one rail lighting fixture, according to any of the preceding claims, and a presence detector for detecting a presence of a person alongside of the rail, wherein the presence detector is arranged to provide a presence detection signal indicative for the presence of a person alongside of the rail, wherein the rail lighting system is arranged to control, based on the presence detection signal, an illumination intensity of the light source of the at least one lighting fixture at a first illumination intensity when the presence detection signal indicates the presence of a person alongside of the rail, and at a second illumination intensity when the presence detection signal does not indicate the presence of a person alongside of the rail, wherein the first intensity exceeds the second intensity.
