Abstract: A lighting device has a light source and a light distributor comprising a lamella grid or, more precisely, a reflective lamella grid. This has two strips parallel to one another and a row of lamellae which are arranged between said strips and, together with the two strips, consist of a single sheet-metal piece. Each lamella has a web and one or two limbs associated with this. Each web is furthermore associated with the two strips. The light distributor furthermore has two lateral walls which serve as lateral reflectors and are formed either by lateral sections of the sheet-metal piece forming the reflective lamella grid or by two originally separate parts connected to the reflective lamella grid. The reflective lamella grid can be produced economically from an originally flat sheet-metal piece with little work.

Abstract: A lighting device has a light source and a light distributor arranged under it. Said light distributor has a distributor element which preferably consists of sheet metal and has an extensive main section with an incidence side facing the light source and a number of holes for the passage of light which widen in the direction away from the incidence side, and a collar for each of said holes. Preferably, a diffuser is arranged above the distributor element and possibly a diaphragm, preferably consisting of sheet metal, is arranged above said diffuser. The light distributor deflects and distributes light radiated downward through it, in such a way that said light makes at least a desired angle of, for example, at least 25° with a horizontal plane. The light distributor can be produced with a small height and economically and has a good antidazzle effect.
