An OLED lighting element comprises a substrate bearing an OLED structure extending laterally over said substrate and sandwiched between first and second electrode layers. The first electrode layer defines a plurality of electrically conductive tracks and said second electrode layer comprises a substantially continuous electrically conducting layer. The OLED lighting element has an electrical bus-bar connected to said electrically conductive tracks extending substantially completely along the or each lateral edge of said lighting element. The electrically conductive tracks run in a radial direction from a laterally central location within said lighting element towards said bus¬ bar along said lateral edges of said lighting element. A said track subdivides into a plurality of tracks with increasing distance from said central location. This arrangement makes more efficient use of the conductive tracks. |
