Zusammenfassung: | The invention provides a luminaire for illuminating a road, comprising a light source (10), a reflector arrangement (12) defining a light entrance window (18) at the top to which light is supplied by the light source (10) and a larger light exit window (20) at the bottom, and an optical plate (22) over the light exit window (20). The optical plate (22) comprises an array of elongate prisms which each extend in a side-to-side direction corresponding to the width direction of the road. The reflector (12) is primarily responsible for control of the light output in the road width direction and the optical plate (22) is primarily responsible for control of the light output in the road length direction. |
