Abstract
A controller for controlling an LED assembly is described. The controller is arranged to—receive an input signal representing a required characteristic of the LED assembly,—convert the input signal to a control signal for the LED assembly,—apply a correction to the control signal to obtain a corrected control signal, the correction being based on a predetermined transient characteristic of the LED assembly,—output the corrected control signal. As such, a better correspondence between a required characteristic and an actual characteristic of the LED assembly is obtained.
Claims21
A controller for controlling an LED assembly, the controller being arranged to
- receive an input signal representing a required characteristic of the LED assembly;
- convert the input signal to a control signal for the LED assembly;
- apply a correction to the control signal to obtain a corrected control signal, the correction being based on a predetermined current slope of a current pulse of the LED assembly, the current slope occurring at a beginning and/or an end of the current pulse;
- and
- output the corrected control signal.
A method of controlling an LED assembly, the method comprising the steps of
- receiving an input signal representing a required characteristic of the LED assembly;
- converting the input signal to a control signal for the LED assembly;
- applying a correction to the control signal to obtain a corrected control signal, the correction being based on a predetermined current slope of a current pulse of the LED assembly, the current slope occurring at a beginning and/or an end of the current pulse;
- and
- outputting the corrected control signal.
