Abstract
Light designer’s task is to aim the football
stadium floodlight to achieve the required levels
of average horizontal and vertical illuminations,
as well as their uniformity. At the same time the
floodlight aiming for higher demand (for example
official games lighting) must incorporate that
some reflectors have a fixed aiming obtained
by optimizing for lower demand (for example
training). It is called the multi–step approach.
In developing of the model and the program
GAVRAS are used the mathematical package
Matlab with its GA toolbox and own old
program for outdoor lighting calculation VRAS.
Implementation of the program GAVRAS is
demonstrated by an example
