    • A light-emitting diode (1) has a first electrode (3), a second electrode (4), a light-emitting layer (5) which comprises a matrix, and ions. A layer (6) of a cation receptor (CR) is positioned adjacent to the first electrode (3), has captured cations, and has generated immobilized cations (+). A layer (7) of an anion receptor (AR) is positioned adjacent to the second electrode (4), has captured anions, and has generated immobilized anions (-). The ion gradients provide for quick response in emission of light (L) when the diode (1) is exposed to a forward bias. A diode (1) is manufactured by first forming a laminate (2) of the above structure. The laminate (2) is exposed to a forward bias to make the ions become immobilized at respective sites (Sl, S2) of the respective receptors (CR, AR).

    • The present invention relates to a control system (13) and method for controlling the light output of an emitting unit (11) having at least one LED (15) and emitting light of at least one colour. The control system (13) comprises a feedback based on a detection unit (19) detecting the light output of the emitting unit (11), a detection pulse generator (27), a suppression unit (23) suppressing environmental light interferences in detected light, and a control unit (21) for controlling the light output of the emitting unit on basis of a comparison between a reference signal representing a desired light output of the emitting unit and an output signal of the suppression unit. The detection pulse generator (27) generates detection pulses a-periodically. Thus, an a-periodicity is introduced into the feedback processing of the light output. This provides a possibility by means of conventional suppression algorithms to eliminate or reduce interfering environmental light, particularly pulsed light.

    • The present invention relates to a method for illuminating a scene having an average lighting setting, the method comprising the steps of receive scene information from an image sensor (110) comprising a plurality of pixels, determine chromaticity coordinates for the scene based on the scene information, and determine, based on the chromaticity coordinates, control values used for driving the at least two differently colored light sources (L 1 , L 2 , L 3 ), thereby allowing for illumination of the scene without essentially changing the average lighting setting of the scene. The present invention provides for the possibility to in a more precise way match the average lighting setting of the scene, wherein it is possible to produced light that assure a more natural rendering of illuminated objects in the scene. In comparison to the prior art, for light sources which have spectra far from the black body curve, the chromaticity coordinates are a better representation of the color of ambient light illuminating the scene than when using the correlated color temperature. The present invention also relates to a corresponding illumination device (100).
