Extensive extended sound absorber board i.e. baffle, for use at ceiling of working place of office, has illumination device extended along narrow side and provided with multiple LEDs, which radiate into room

摘要

The board (4) has a fixation device (6) i.e. rope fixation device (8), for fixing a board at a ceiling or a wall of a room in a vertical orientation manner. An illumination device (16) is extended along a narrow side (14), and provided with multiple LEDs, which radiate into the room. The illumination device exhibits a supporting bar for the LEDs, where the supporting bar forms a visible edge of the board. The supporting bar comprises a profile bar i.e. acryl profile bar. The illumination device has an optical effective lens unit for radiation of LEDs.
