Abstract (en)

[origin: WO2014177535A1] The invention relates to a method for altering the colour location of the visible light emitted by an LED module, said LED module having at least two parallel LED sections, each section having at least one LED and the emission spectra of the LED sections being different. The LED sections are operated alternately with a constant current and in order to alter the colour location, the relationship between the activation periods of the LED sections is altered, preferably whilst maintaining the sum of the activation periods of all the LED sections.
