In left plots, specific illuminances by a continuous row of luminaires spaced 5 and 6 heights are shown in their left halves (right half concerns a single luminaire). | The right plot is for a single luminaire, unrotated. |
Values below the scale are illuminance / 1 lx. This is for (unrealistic) “unit” case that luminaires would have lamps producing 1 klm only, would be point-like and just 1 m over the terrain.
