发明名称 DISPOSITIVO DE ILUMINAÇÃO COM DIODO EMISSOR DE LUZ
摘要 The present invention relates to a light emitting diode (LED) lighting device (10). The device comprises a light guide plate (12), a plurality of LEDs (14) for emitting light into the light guide plate, a plurality of out-coupling structures (20) adapted to extract light from the light guide plate, and first and second electrodes (22, 24) connected to the LEDs. The first electrode is arranged at one side (28) of the light guide plate and the second electrode is arranged at the other side (30) of the light guide plate.
