Abstract
The invention relates to a luminaire for road illumination, said luminaire () comprising a housing () containing a light source () provided with optics (). The luminaire further comprising a sensor unit () adapted to measure optical properties of the surrounding of the luminaire and a calculation unit adapted to calculate the parameters for controlling the light output of the luminaire based on the optical properties measured by the sensor unit. According to the invention, the sensor unit is adapted to measure specular and diffuse reflection properties of the surrounding of the luminaire. These optical properties allow determining the type of weather or the road condition and adjustment of the light output of the luminaire, thus improving the road safety.
