Was ist das Leuchtdichte-Verh\u00e4ltnis?<\/h2>

Das Leuchtdichteverh\u00e4ltnis ist das Verh\u00e4ltnis der durchschnittlichen Leuchtdichte zur Fensterleuchtdichte. Es dient als Indikator f\u00fcr den Helligkeitskontrast zwischen einer Tageslichtquelle und dem gesamten Gesichtsfeld. Dieses Verh\u00e4ltnis wird als Variable in Modellen verwendet, die die Leistung von Beleuchtungssystemen analysieren und vergleichen, wobei Faktoren wie die vertikale Beleuchtungsst\u00e4rke, die Position des Schattens und das Leuchtdichteverh\u00e4ltnis ber\u00fccksichtigt werden.<\/p>

Das Leuchtdichteverh\u00e4ltnis ist n\u00fctzlich bei der Bewertung der optischen Leistung und Qualit\u00e4t von Beleuchtungssystemen und elektronischen Ger\u00e4ten, insbesondere von Displays. Es wird als Parameter bei der Pr\u00fcfung von Leuchtdichteverh\u00e4ltnis, Farbe und Gleichm\u00e4\u00dfigkeit verwendet. Durch die Bewertung des Leuchtdichteverh\u00e4ltnisses lassen sich die Lesbarkeit und der Sehkomfort eines Bildschirms bestimmen, wobei die Helligkeit des Umgebungslichts im Verh\u00e4ltnis zur Bildschirmhelligkeit ber\u00fccksichtigt wird.<\/p>

Au\u00dferdem ist das Leuchtdichteverh\u00e4ltnis f\u00fcr das Verst\u00e4ndnis des wahrgenommenen Kontrasts und des Sehkomforts von wesentlicher Bedeutung. Bei Hell-auf-Dunkel-Symbolen beispielsweise beeinflusst das Leuchtdichteverh\u00e4ltnis zwischen dem Hintergrund und den leuchtst\u00e4rksten Pixeln, aus denen das Symbol besteht, den wahrgenommenen Kontrast. In Leitlinien werden bestimmte Leuchtdichteverh\u00e4ltnisse zwischen Objekten und ihren Hintergr\u00fcnden empfohlen, die sich nach dem gew\u00fcnschten Grad der Auff\u00e4lligkeit richten und die Rolle des Leuchtdichteverh\u00e4ltnisses bei der Verbesserung der Sichtbarkeit und des Sehkomforts unterstreichen.<\/p>

Dar\u00fcber hinaus ist das Leuchtdichteverh\u00e4ltnis auch ein Faktor bei der Bewertung der Ungleichm\u00e4\u00dfigkeit und der Innenbeleuchtungsmetriken. Die Illuminating Engineering Society of North America (IESNA) hat Richtlinien aufgestellt, die akzeptable Werte f\u00fcr die Ungleichm\u00e4\u00dfigkeit anhand von Leuchtdichteverh\u00e4ltnissen zwischen den Oberfl\u00e4chen im Sichtfeld definieren. Eine genaue Darstellung der Leuchtdichteverteilung von Fenstern und der Leuchtdichteverh\u00e4ltnisse in Innenr\u00e4umen ist entscheidend f\u00fcr die Bewertung des Sehkomforts und der Leistungskennzahlen mit Techniken wie Image-Based Lighting (IBL).<\/p>","protected":false},"excerpt":{"rendered":"
