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.
