| 摘要 |
The invention relates to an optical projection device. Said optical projection device comprises a plurality of light-emitting diode chips (1) and at least one optical element (2) comprising a light input surface (22) which is associated with at least one of the light-emitting diode chips (1). The light decoupling surface (100) of the light-emitting diode chip (1), which is adapted to the refraction index, is optically connected to the light input surface (22) of the associated optical element (2). ® KIPO & WIPO 2009 |
