Was ist das Leuchtdichteverh\u00e4ltnis<\/h2>\n\n\n

Das Leuchtdichteverh\u00e4ltnis ist das Verh\u00e4ltnis der mittleren Leuchtdichte zur Fensterleuchtdichte. Es dient als Indikator f\u00fcr den Helligkeitskontrast zwischen einer Tageslichtquelle und dem gesamten Sehfeld. Dieses Verh\u00e4ltnis wird als Variable in Modellen verwendet, die die Leistung von Beleuchtungssystemen unter Ber\u00fccksichtigung von Faktoren wie vertikaler Beleuchtungsst\u00e4rke, Position des Sonnenschutzes und Leuchtdichteverh\u00e4ltnis analysieren und vergleichen.<\/p>\n

Das Leuchtdichteverh\u00e4ltnis ist n\u00fctzlich bei der Beurteilung der optischen Leistung und Qualit\u00e4t von Beleuchtungssystemen und elektronischen Ger\u00e4ten, insbesondere von Displays. Es wird als Parameter bei Pr\u00fcfungen bez\u00fcglich Leuchtdichteverh\u00e4ltnis, Farbe und Gleichm\u00e4\u00dfigkeit verwendet. Durch die Auswertung des Leuchtdichteverh\u00e4ltnisses lassen sich die Lesbarkeit und der Sehkomfort eines Displays unter Ber\u00fccksichtigung der Umgebungshelligkeit im Verh\u00e4ltnis zur Bildschirmhelligkeit bestimmen.<\/p>\n\n\n\n

Dar\u00fcber hinaus ist das Leuchtdichteverh\u00e4ltnis essenziell f\u00fcr das Verst\u00e4ndnis des wahrgenommenen Kontrasts und des Sehkomforts. Beispielsweise beeinflusst bei einer Hell-auf-Dunkel-Darstellung von Symbolen das Leuchtdichteverh\u00e4ltnis zwischen dem Hintergrund und den leuchtst\u00e4rksten Pixeln des Symbols den wahrgenommenen Kontrast. Richtlinien empfehlen spezifische Leuchtdichteverh\u00e4ltnisse zwischen Objekten und ihrem Hintergrund basierend auf dem gew\u00fcnschten Grad an Auff\u00e4lligkeit (Conspicuity oder Saliency) und unterstreichen damit die Rolle des Leuchtdichteverh\u00e4ltnisses bei der Verbesserung der Sichtbarkeit und des Sehkomforts.<\/p>\n

Zus\u00e4tzlich ist das Leuchtdichteverh\u00e4ltnis ein Faktor bei der Bewertung von Ungleichm\u00e4\u00dfigkeiten und Innenraumbeleuchtungskennzahlen. Die Illuminating Engineering Society of North America (IESNA) hat Richtlinien festgelegt, die akzeptable Stufen der Ungleichm\u00e4\u00dfigkeit mithilfe von Leuchtdichteverh\u00e4ltnissen zwischen Fl\u00e4chen im Sehfeld definieren. Eine pr\u00e4zise Darstellung von Fensterleuchtdichteverteilungen und Innenraum-Leuchtdichteverh\u00e4ltnissen ist entscheidend f\u00fcr die Bewertung des Sehkomforts und von Leistungskennzahlen unter Verwendung von Verfahren wie dem image-basierten Beleuchten (Image-Based Lighting, IBL).<\/p>","protected":false},"excerpt":{"rendered":"
