Lighting device

摘要

There is provided a lighting device and a method to manufacture such a lighting device. The inventive concept is based on manufacturing a lighting device on an at least partly flexible sheet assembly which is rolled into a tube, such that the light source of the lighting device is arranged within the tube. The flexible sheet assembly is arranged such that the tube provides a light mixing chamber and light exit surface for the lighting device. Thus, the tube shaped lighting device instantly delivers the necessary optical and mechanical properties for easy assembly and the functionality of a light engine.
