A: Ƙimar takardar bayani yawanci ana auna su a zafin haɗuwa (Tj) na 25°C a ƙarƙashin yanayin bugun jini. A aikace-aikace na ainihi, mafi girman Tj saboda rashin isasshen ajiye zafi yana haifar da raguwar ƙarfin haske. Dubi lakatar ƙarfin haske mai dangi da zafi.

Q: Ta yaya zan fassara lokacin da ya ƙare "Har Abada"?

A: Yana nufin wannan takamaiman sake dubawa (Rev. 2) ba shi da tsarin ƙarewa. Shi ne ingantaccen ƙayyadaddun bayani don wannan sigar samfur. Koyaushe bincika sabbin sake dubawa kafin a kammala ƙira.

11. Misalan Amfani na Ainihi

Misali 1: Hasken Layi na Gine-gine:Don ci gaba da gudanar da kaset ɗin LED, zaɓin LED daga ƙarfin hasken haske da rukunin launi ɗaya yana da mahimmanci don guje wa sauye-sauyen haske ko launi da ake iya gani tare da tsayi. Bayanin rarraba (binning) na takarda yana jagorantar wannan zaɓi. Gudanar da zafi ya haɗa da ƙirar tashar aluminum don yin aiki azaman mai sanyaya zafi, kiyaye Tj ƙasa don kiyaye haske da tsawon rayuwa.

Misali 2: Fitilar Alamar Mota:A nan, aminci a ƙarƙashin yanayi mai tsanani (jujjuyawar zafi, girgiza) shine maɓalli. Matsakaicin ƙima da halayen zafi na takardar bayani suna sanar da ƙirar tushen PCB da matakin tuƙi don tabbatar da aiki har tsawon rayuwar motar. Ana kuma amfani da ikon sauyawa da sauri na LED.

12. Gabatarwa akan Ka'idar Aiki

LED diode ne na semiconductor. Lokacin da aka yi amfani da ƙarfin lantarki na gaba, electrons daga kayan n-type suna sake haɗuwa da ramuka daga kayan p-type a cikin yanki mai aiki, suna sakin makamashi a cikin nau'in photons (haske). Tsawon zango (launi) na hasken da aka fitar yana ƙaddara ta hanyar tazarar bandgap na kayan semiconductor da aka yi amfani da su (misali InGaN don blue/green, AlInGaP don red/amber). Fararen LED yawanci ana ƙirƙira su ta hanyar lulluɓe guntu LED blue da phosphor rawaya; haɗuwar hasken blue da rawaya yana bayyana fari ga idon ɗan adam.

13. Trends na Fasaha

Babban yanayin fasahar LED yana mai da hankali kan fagage masu mahimmanci da yawa:Ƙara Ingantaccen Aiki, samun ƙarin lumens a kowace watt na lantarki, rage amfani da makamashi.Ingantaccen Ingancin Launi, faɗaɗa gamut da samun mafi girman ƙimar CRI tare da mafi daidaiton rarraba bakan.Ƙananan Girma, ba da damar nuni mai yawan pixel (micro-LEDs) da haɗawa cikin ƙananan na'urori.Ingantaccen Aminci, tare da tsawon rayuwar aiki (L90) da mafi kyawun aiki a ƙarƙashin yanayin zafi da danshi mai yawa.Haɗin Kai mai Hikima, haɗa masu tuƙi, na'urori masu auna firikwensin, da hanyoyin sadarwa kai tsaye cikin kunshin don tsarin haske mai hikima.
