7.3 Tambayoyin da Ake Yawan Yi (FAQs) Dangane da Sigogi

Q: Zan iya turawa wannan LED a 30mA ci gaba?

• A: Ee, amma kawai idan yanayin zafin muhalli yana ko ƙasa da 30°C. Sama da 30°C, dole ne a rage halin yanzu bisa ga ƙayyadaddun (0.45 mA/°C). A 85°C, matsakaicin halin yanzu na ci gaba zai kasance ƙasa da haka sosai.
  
  Q: Me ya sa ake buƙatar resistor na jere ko da ƙarfin lantarki na wadata ya yi daidai da VF na LED?
• A: VF ƙimar suna ce ne tare da kewayon (2.5V-3.1V) kuma yana dogara da zafin jiki. Ana buƙatar resistor don daidaita halin yanzu, yana hana guduwar zafi wanda zai iya faruwa idan ɗan ƙaramin ƙaruwar zafin jiki ya rage VF, yana haifar da ƙaruwar halin yanzu ba tare da sarrafawa ba.
  
  Q: Me bayanin "Ruwa Bayyananne" na ruwan tabarau yake nufi?
• A: Yana nuna cewa ruwan tabarau ba ya watsawa, yana haifar da ƙirar haske mai mai da hankali kamar yadda kusurwar dubawa ta digiri 15 ta ayyana, idan aka kwatanta da ruwan tabarau mai watsawa wanda zai haifar da ƙirar haske mai faɗi, mai laushi.
  
  A: It indicates the lens is non-diffused, resulting in a more focused beam pattern as defined by the 15-degree viewing angle, compared to a diffused lens which would create a wider, softer light pattern.
