摘要
Method of lighting in a cold light of a moving product intended for the acquisition of images by linear digital cameras, for a system for detecting faults, with the aid of a device comprising a light source formed of light-emitting diodes (4) of power. According to this process is available, the light-emitting diodes (4) in at least one row, aligned in equal intervals, in a housing forming a kind of light box to the walls (55, 65) reflecting, it produces a light diffusion of the light from the light-emitting diodes by a film (7) closes the light box, and it concentrates the light rays emerging from the light box with the aid of a reflecting device (8), a light beam which is flat and narrow, whose width is substantially equal to the length occupied by the alignment of the diodes. The lighting device (r) is closed by a casing made of an airtight tube (13) is closed at its two ends and provided with a window (9) provided with a transparent window (10) arranged substantially over the entire length of said envelope in order to allow the passage of the illumination light. The airtight tube (13) is ventilated and cooled.
