| Title: |
Method of Controlling Illumination Device Based on Current-Voltage Model |
| Abstract: |
The present invention relates to an illumination device including a
number of LEDs and a processor for receiving an input signal and
generating an activation signal for at least one of the LEDs based on the
input signal. The illumination device further comprises an LED driver for
obtaining the voltage across and current through the LED. The processor
may generate the activation signal based on the voltage, the current and
a current-voltage model related to the LED. The current-voltage model
defines a relationship between the current, the voltage and the
colorimetric properties of light emitted by the LED. The present
invention relates also to a method of controlling and a method of
calibrating such an illumination device.
