Floodlight for illuminating a semicircular vault

摘要

A method of designing the profile of an asymmetric floodlight reflector for illuminating semicircular vaults with a constant illuminance is described. Only directional reflector surface reflection was assumed, and the location of the floodlight with respect to the illuminated surface was explicitly defined, in the calculations the effect of the cover on the luminous flux distribution is taken into account.
