Illumination apparatus for visual and camera supported error control, comprises of reflecting surface bent only on longitudinal side, whose cross section describes parabolic section

摘要

The illumination apparatus comprises a reflecting surface bent only on longitudinal side, whose cross section describes a parabolic section. A cross sectional middle point of a rod shaper light source is located in the focus of the reflection surface, and a screening unit encloses the light source. The cross section of the screening unit is part of the angle in the area of light outlet opening, whose vertex lies in the cross sectional middle point of the light source and whose shank goes through each of the end points of the parabolic section of the reflecting surface.
