Abstract:
The present invention relates to a light emitting diode (LED) lighting device (10). The lighting device comprises a light guide plate (12), and a plurality of LEDs (16) accommodated in holes (14) arranged in the plane of the light guide. At least one hole has a first side facet (18) for coupling light from any LED in the hole into the light guide and a second opposite side facet (20) for coupling light out of the light guide. Further, the holes are arranged such that all first side facets are facing one direction. Such an LED based lighting device can be made thin and unobtrusive.
