Pendelleuchte überwiegend indirektPendant light predominantly indirect

mit geringer Leuchtdichte der Unterseitewith low luminance of the underside

BeschreibungDescription

Nur Indirektleuchten sind unabhängig von der Möblierung bildschirmarbeitsplatzgerecht. Only indirect lighting is suitable for computer workstations, regardless of the furniture.

Direkt/indirekt strahlende Leuchten können zum Schutz vor störenden Reflexen auf der Tischebene nur raöblierungsbezogen korrekt verwendet werden.To protect against disturbing reflections on the table surface, direct/indirect luminaires can only be used correctly in relation to the furnishings.

Die vorliegende überwiegend indirekt strahlende Leuchte besitzt für alle Ausstrahlungswinkel so geringe Leuchtdichten, daßThe present predominantly indirect luminaire has such low luminance for all beam angles that

- Bildschirme unabhängig von der Neigung- Screens independent of inclination

- alle sonstigen mehr oder weniger glänzenden Arbeitsmittel- all other more or less shiny work tools

reflexfrei sind (Bildschirmarbeitsverordnung). Sindelfingen, den 9.4.01are reflex-free (Screen Work Regulations). Sindelfingen, 9.4.01
