ABSTRACT:
The invention relates to an optical projection device. Said optical projection device comprises a plurality of light-emitting diode chips and at least one optical element comprising a light input surface which is associated with at least one of the light-emitting diode chips. The light decoupling surface of the light-emitting diode chip, which is adapted to the refraction index, is optically connected to the light input surface of the associated optical element.
