Half-cylindrical illuminance
Semi-cylindrical illuminance - a characteristic describing the saturation of space with light and the shadow-forming effect of illumination for an observer moving along the street parallel to its axis. It is determined as the average density of the luminous flux on the surface of a semi-cylinder vertically positioned along the longitudinal line of the street at a height of 1.5 m, whose radius and height tend towards zero. Calculation of semi-cylindrical illuminance is performed using the engineering method
