摘要：
The present invention relates to a lighting device (10). The device comprises a light guide plate (12), and at least one array (14) of light emitting diodes (LEDs) (16), which LEDs are accommodated in holes (20) arranged in the light guide plate. The device is characterized by an array (24) of lenses (26) arranged such that light emitted by the LEDs passing the lens array is at least partly directed towards areas (28) of the light guide plate free from holes.
