12 Claims

1. A computer-implemented method for controlling two light modules, the method comprising:

supplying a first light module with a first electric power and a second light module with a second electric power;

determining a first temperature of the first light module and a second temperature of the second light module; and

adjusting the first and second electric power as a function of the first and second temperature,

wherein the adjustment of the first and second electric power occurs as a function of a difference between the first temperature and the second temperature, and

wherein the adjustment of the first and second electric power is performed using a sigmoid function, and

wherein the sigmoid function is defined by the following formula;

where t is the difference between the first and second temperature, and where k is an adjustable constant.
