Abstract:
In a lighting device with at least one continuous OLED layer (4) with a first electrode layer (5), a second electrode layer (6) and a plurality of optical collimating means, the second electrode layer (6) is only in electrical contact with the OLED layer (4) within spaced sections (6a), arranged within acceptance angles of the collimating means. Such a lighting device can be manufactured efficiently and is highly energy-efficient.
