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.
