Abstract

It is described a lamp (6) with a 3D illuminating area (7). The lamp (6) comprises a plurality of organic light emitting diode (OLED) units (1) and each OLED unit (1) comprises a light emitting region (8-12) to form a part of the illuminating area (7). The lamp (6) enables a desired light distribution (beam shaping) and is preferably configured as a high brightness light sources and light sources with increased lifetime and improved co lor mixing. The configuration with a plurality of OLED units (1) offers design freedom and provides integrated light sources. Further, the invention may reduce the well known heat problem.
