Lighting density calculation
WebThe Interior Tool will calculate the number of luminaires needed to meet an average illuminance across the workplane for an enclosed rectangular room using the principals of the lumen method. You can also use the Interior tool to determine the illuminance achieved by a specified lighting power density or luminaire quantity. Advantages: WebDensity of states calculation will shed some more light on the photoexcitation process, as direct correspondence of 1 photon-1 electron excitation need review at a deeper level.
