Abstract: A method of designing a lighting panel includes the steps of determining a level of lumen output to be achieved from the lighting panel, selecting one or more types of LEDs having a predetermined light intensity and light output angle, calculating the number of LEDs required to achieve the level of lumen output, and arranging the LEDs in an array. The LEDs are oriented such that the light output angle is centered on a light diffuser panel. The LEDs are spaced in the array and spaced from the light diffuser panel such that the light output from LEDs overlaps on the light diffuser panel such that the light transmitted through the diffuser panel appears consistent across the light diffuser panel to the human eye and achieves the determined level of lumen output.
