  • Street lighting has specific peculiarities related to the reflection characteristics of the street surface, which is, in general, not isotropic.
  • the light is reflected as a function of the angles of incidence and of reflection of the light on the street surface and thus, to optimise the street lighting and avoid dangerous shadow areas, the light output must be directed where it is most effective, i.e., in the direction in which the luminance is greater and more uniform.
  • the light output must be directed to the areas of the street surface in which the ration between the resulting luminance and the illumination is greater in order to achieve better lighting results with less light output, and in the areas in which the resulting luminance is more uniform, so as to respect the parameters of uniformity of illumination prescribed by current regulations.
  • the individual LEDs are generally arranged on the same plane and the light must be deflected in the desired directions in order to achieve the overall band of illumination desired.
