Abstract
Practical design calculations must be simple and high accuracy is rarely required. The widely used lumen-method is becoming increasingly dependable; local lighting methods are nevertheless indispensable. The applicability of the point source concept is discussed, and the principles of line source calculations using the sector flux concept are briefly given. An example shows the combined use of point and line source methods. Flux relations are summarized.
