Claim:
1. A lighting device comprising; a support panel located between two outer sheets, each of the outer sheets having two parallel longitudinal sides, the outer sheets being movable with respect to each other between a folded state and an unfolded state; wherein, in the folded state, the outer sheets are flat and extend substantially parallel to the support panel, wherein, in the unfolded state, the outer sheets are curved and at least partly further spaced apart than in the folded state, wherein the two parallel longitudinal sides of a first one of the two outer sheets are connected to the respective two parallel longitudinal sides of a second one of the two outer sheets to form first and second sets of interconnected longitudinal sides, wherein the first and second sets of interconnected longitudinal sides are movable towards each other to push the outer sheets spatially apart from each other in the unfolded state, and wherein the support panel comprises at least a light emitting diode as a light emitting module and is located between the outer sheets in the folded state and the unfolded state, said light emitting diode facing at least one of the outer sheets.
