Claim 18:
19. A lighting apparatus comprising:
a flexible planar light source comprising a plurality of illuminants distributed over a surface of a planar carrier material, the carrier material comprises a flexible planar circuit carrier fitted with the plurality of illuminants on a front side, the illuminants being interconnected by electrical lines formed in or on the circuit carrier, and
a controller configured to supply power to the plurality of illuminants and control the plurality of illuminants,
wherein the controller comprises a housing disposed on an edge of the planar light source and is mechanically connected to the planar light source, an edge of the planar light source being partly accommodated in the housing,
the housing comprising electrical and electronic components and lines connected to the electrical lines of the planar light source;
a strain relief is configured to absorb tensile stresses between the housing and the planar light source to keep the tensile stresses away from electrical connections between the controller and the planar light source; and
a stiffenable frame connected to the planar light source at least partially circumferentially, the frame stretching the planar light source in the stiffened state and allowing the planar light source to be one or more of folded and rolled up together with the stiffenable frame in the unstiffened state.
