1. A method for controlling light being emitted from a light-emitting system comprising a plurality of light emitting diodes (LEDs), said method comprising controlling at least the following parameters:

  • the temperature of the surroundings of each of the LEDs, a luminous flux of each of the LEDs, and an electrical power being supplied to each of the LEDs, and where controlling the surrounding temperature controls a luminous intensity being emitted from the system, thus controlling the luminous flux of the LEDs, and controlling the electrical power does not decrease the lifetime of the LEDs by the current of the electrical power not being increased during the lifetime of the LEDs.
