| 摘要 |
The present invention relates to an illumination system ( 300 ) comprising a light guide ( 302 ) having an entrance face, an exit face and an aperture in which a light source ( 301 ) can be arranged, and a display system comprising such an illumination system ( 300 ). The idea of the present invention is that various elements ( 306, 307 ) are arranged in the light guide ( 302 ) to increase the angle of light beams incident in the light guide ( 302 ) with respect to the optical axis ( 304 ) of the system ( 300 ) and to create a homogeneous illumination at the exit face of the light guide ( 302 ). The present invention is advantageous, since the claimed illumination system ( 300 ) decreases the length of a given light guide ( 302 ), making the illumination system ( 300 ) smaller, lighter and more compact with even illumination and a high optical efficiency.
