Lighting device, has optical arrangement with beam formation element and optical element and optical element is arranged between beam formation element and light emitting surface

摘要

The lighting device has multiple light emitting semiconductor components (1) and light emitting surface (2), by which multiple optical arrangements are arranged between the components (1) and the surface (2), such that a component (1) illuminates one or more optical arrangements in the operation of the lighting device. An optical arrangement has a beam formation element (4) and optical element (5). The element (5) is arranged between the element (4) and the surface (2). A part of a light coming out during the operation of lighting device is absorbed or reflected or controlled by element (4).
