Claim:
1. A method for arranging at least two colors of light emitting diodes (LEDs) for phototherapeutic treatment, the method comprising the steps of: a) selecting a first number of LEDs for a first emission color and at least one second number of LEDs for at least one next emission color; b) selecting a random arrangement of the first number and the at least one second number of LEDs for a set of locations; c) calculating a first weighted sum of distances between each LED of the first color; d) calculating at least one next weighted sum of distances between each LED of the at least one next color; e) obtaining a figure of merit by summing the first weighted sum with the at least one next weighted sum; f) switching a placement of two randomly selected LEDs; g) recalculating a new figure of merit; h) if the new figure of merit is increased, maintaining the placement, if the new figure of merit is decreased, reverting to an original placement of the two randomly selected LEDs; i) switching a next placement of two next randomly selected LEDs; and j) repeating steps c) through h) until no further increase on a next figure of merit is calculated.
