1. Bayyani Game da Samfur

Wannan takardar fasaha tana ba da cikakken bayani game da rayuwar samfur da sarrafa sake dubawa na wani kayan lantarki na musamman, wanda aka gano a nan a matsayin LED don dalilai na mahallin. Babban bayanin da aka isar shi ne kafa tabbataccen matsayi na sake dubawa, wanda aka keɓance a matsayin Sake Dubawa Na 3. Wannan sake dubawa yana da matsayi na dindindin, wanda aka nuna ta hanyar "Lokacin Ƙarewa" na "Har Abada," yana nuna cewa wannan sigar ƙayyadaddun bayanai an yi niyya ta kasance mai inganci kuma ana iya komawa gare ta har abada ba tare da tsara tsufa ba. Cikakken lokacin sakin wannan sake dubawa shine ranar 15 ga Nuwamba, 2013, da karfe 08:38:52.0. Yawaitar bayanan da aka bayar yana jaddada tsarin rikodin daidaitaccen tsari ko tsarin lakabi, wanda wataƙila aka yi amfani da shi a cikin raka'a, gungu, ko shafukan takardu da yawa don tabbatar da bin diddigin bayanai da daidaito.

2. Zurfin Binciken Ma'auni na Fasaha

Duk da yake ba a ƙididdige takamaiman ma'auni na haske, lantarki, da zafi a cikin guntun bayanin da aka bayar ba, tsarin takardar yana nuna tushe mai ƙarfi na fasaha. Cikakken takardar bayanai na kayan LED yawanci zai haɗa da sassan masu zuwa, waɗanda suke da mahimmanci ga injiniyoyin ƙira:

2.1 Halayen Hasken Hasken

Wannan sashe zai yi cikakken bayani game da kaddarorin fitar da haske. Ma'auni masu mahimmanci sun haɗa da Juzu'in Hasken (wanda aka auna a cikin lumens, lm), wanda ke ayyana jimillar ƙarfin hasken da ake fitarwa. Ƙarfin Hasken (candelas, cd) yana bayyana haske mai shugabanci. Tsawon zango ko zafin launi mai alaƙa (CCT, a cikin Kelvin) yana ƙayyade launin hasken da ake fitarwa, ko farin sanyi, farin dumi, ko takamaiman launi kamar ja ko shuɗi. Ma'aunin Bayyana Launi (CRI) shi ma ma'auni ne mai mahimmanci, yana nuna yadda tushen haske ke bayyana ainihin launukan abubuwa idan aka kwatanta da hasken yanayi.

2.2 Ma'auni na Lantarki

Ƙayyadaddun lantarki sune tushe don ƙirar da'ira. Ƙarfin Lantarki na Gaba (Vf) shine raguwar ƙarfin lantarki a kan LED lokacin da yake aiki a ƙarfin halin yanzu na yau da kullun. Yana bambanta da kayan semiconductor (misali, ~3.2V ga yawanci InGaN blue/white LEDs, ~2.0V ga AlGaInP red LEDs). Ƙarfin Lantarki na Gaba (If) shine ƙarfin lantarki na aiki da aka ba da shawarar, sau da yawa 20mA, 150mA, ko mafi girma ga manyan LED. Ƙarfin Lantarki na Baya (Vr) yana ƙayyade matsakaicin ƙarfin lantarki da aka yarda a cikin hanyar baya kafin yuwuwar lalacewa. Ana iya ƙayyade juriya mai ƙarfi don dalilai na ƙira.
