Claim:
A lighting device of a scrolling product for the detection of surface faults constituted by a closed mechanical support assembly forming an elongated box constituting a striplight and comprising: a plurality of high-power light-emitting diodes aligned in at least one row and arranged side by side according to a regular pitch; a light guide with flat and reflecting walls, parallel to one another and located in planes substantially parallel to a plane formed by axes of the light-emitting diodes; a film made of translucent and diffusing material arranged on a trajectory of light beams emitted by the light-emitting diodes; a reflector for concentrating and sending back the light beams to an exterior of a closed support through a window forming an elongated opening arranged substantially over a length of the striplight; and a transparent lid for closing the opening arranged in the striplight while letting the light beams emanating from the light-emitting diodes pass to the exterior.
