Abstract
The invention relates to a light source comprising one or more organic light emitting devices mounted on a mounting substrate, each of the organic light emitting devices comprising a first electrode which is light transmissive, an organic light emitting layer, a second electrode, a first device electrical contact extending from the first electrode to the mounting substrate, and a second device electrical contact extending from the second electrode to the mounting substrate. The invention also relates to a method of making such a light source.
