22. A method for calculating the illumination intensity on a target surface provided by a plurality of light sources disposed in one location above the target surface, each light source providing a cone of light where the axis of the cone has the highest light intensity and the boundary of the cone represents a lesser percentage of the wavelength radiation intensity from the center, comprising:
-
a) subdividing the target surface into grids;
b) for each grid, calculating the light intensity provided by each light source by taking the cross product of a location vector represented by a line connecting the light source and the grid, and an aiming vector represented by the cone axis;
c) calculating the angle between the location vector and the aiming vector;
d) if the angle is less than one-half the cone angle, calculating the primary lighting intensity at the grid;
e) plotting the total light intensity at each grid. - View Dependent Claims (23, 24)
