Na jakou hodnotu se dívat u světelných zdrojů?
Na různých světelných zdrojích jsou různé hodnoty a jednotky. افتتاح اليورو 2024 Nejdůležitější je údaj o světelném toku. Ten však často na zdrojích světla nenajdete. Proto je třeba alespoň orientačně vědět, jak se tato hodnota pohybuje.
U žárovek je to cca 10 lm/watt, u úsporných zářivek cca 50 lm/watt a největší světelný tok mají lineární zářivky – až 100 lm/watt.
Máme sice světelné zdroje s ještě větším světelným tokem – třeba nízkotlaké sodíkové výbojky, mají však špatný index barevného podání, jedná se o monochromatické světlo.
Další údaj je teplota chromatičnosti – např. 2700K, 3000 K, 5600 K. To určuje bělost/žlutost světla. Kdybychom vzali kus tyče a dali ji do plamene a zahřáli třeba na 3000 Kelvinů tak uvidíme onu barvu zdroje. مراهنات كرة القدم اليوم
Údaj, který je tam vždy je příkon ve wattech. لعبة طاولة 31 على الانترنت Ovšem protože už známe světelný tok, tak víme že 10 W u zářivky je asi tolik, kolik 100 W užárovky. Tak pozor na to 🙂
