An illumination system has at least one organic light-emitting diode (1) deposited on a rigid and translucent substrate (11). The organic light-emitting diode includes first (3) and second (4) electrodes for providing electrical power to the organic light-emitting diode. The substrate at a side facing away from the organic light-emitting diode is arranged on a translucent waveguide (15). The waveguide at a side facing away from the organic light-emitting diode is provided with means (25) for coupling out light emitted by the organic light-emitting diode. In operation, light generated by the organic light-emitting diode travels through the substrate and the waveguide and is emitted by the illumination system in a direction substantially normal to the waveguide. Preferably, the illumination system comprises a plurality of organic light-emitting diodes arranged on the translucent waveguide. According to the invention, light emission by the illumination system is improved. |
