ABSTRACT:
The invention relates to a lighting device for installation in a substantially plane surface, for example, the surface of a runway. The lighting device comprises at least one lamp unit that emits light essentially in a light direction which forms an angle α with an axis at right angles to the substantially plane surface. Furthermore, the lighting device comprises at least one light refracting means having a longitudinal direction coincident with the light direction, an incident face substantially at right angles to the light direction, and an exit face parallel to the substantially plane surface. The light refracting means is preferably a prism grating. The lighting means is characterised in that the light refracting means is supported by a supporting means that extends along the whole of or a substantial part of the length of the light refracting means, and which preferably envelops the side faces of the light refracting means.
