Enamelled surface quality monitoring lamp operating according to simultaneous contrast law

摘要

The lamp is operated by focussing the lamp (2), the highly polished anodised spherical mirror (1) for the light density increase of the lamp, and for the uniform, sharply limited luminous light flux distribution, is only aligned on the prism opening (12). In addition with the white reflector (4), the wide radiating light density distribution is reached on the prism optic (5). The lamp is equipped with a manual holder adjustment (3) with regard to the selected position, for matching the vision task. For deciding of matt and diffused surfaces, concn. lenses or a scatter lens (7-9) are available, which can be fitted without tool at the holder carrier (11). The lamp is constructed with a light density regulator (13) in the dark field (10). For visibility matching with the human eye, it is designed in conjunction with a regulatable electronic starter unit.
