Abstract:
A method for calibrating a light emitting diode (LED) of a red-green-blue type is arranged for setting a pulse width modulation duty cycle and for supplying to the LED either a current having a first value or a current having a second value higher than the first value.

Claim (Index 11):
A Red-green-blue Light Emitting Diode, RGB LED, device comprising\n a red, green and blue LED, pulse width modulation, PWM, control means for setting a PWM duty cycle value, current supply means for supplying to said LEDs either a current having a first value or a current having a second value higher than said first value, a controller comprising a processing means arranged for receiving information on a target colour point and target intensity, calculating from a measured first set of tristimulus values parameters to express colour intensity as a function of PWM duty cycle when said current having said first value is applied, calculating from a measured second and third set of tristimulus values parameters to express colour intensity as a function of PWM duty cycle when said current having said second value is applied, said second set measured when said current having said second value is applied with a second PWM duty cycle, said second PWM duty cycle lower than said first PWM cycle, whereby the resulting current is lower than the current resulting when said current having said first value is applied with said first PWM duty cycle, said third set of tristimulus values measured when said current having said second value is applied with a third PWM duty cycle, said third PWM duty cycle higher than said first PWM cycle, whereby the resulting current is higher than the current resulting when said current having said first value is applied with said first PWM duty cycle, said RGB LED device further comprising storage means for storing said calculated parameters.
