Ƙarfin 1mA/sashi mai ƙarancin ƙarfi yana ba da damar amfani da resistors masu iyakancewa mafi girma, yana rage jimillar wutar lantarki na tsarin kuma yana tsawaita rayuwar baturi sosai idan aka kwatanta da nuni na yau da kullun na 20mA.

11. Gabatarwar Ka'idar Aiki

Nuni na LED mai sassa bakwai tarin diodes ne masu fitar da haske waɗanda aka jera a cikin tsarin siffar takwas. Ta hanyar zaɓin wutar lantarki na haɗuwa daban-daban na sassa bakwai (da zaɓi ma'auni), ana iya samar da duk lambobi na lambobi (0-9) da wasu haruffa. A cikin tsarin anode gama gari kamar LTD-6710JD, duk anodes na LED na lamba ɗaya an haɗa su tare zuwa fil ɗin ƙarfin wutar lantarki gama gari. Don haskaka takamaiman sashi, an haɗa fil ɗin cathode ɗinsa zuwa ƙaramin ƙarfin wutar lantarki (yawanci ƙasa) ta hanyar resistor mai iyakancewa, yana kammala da'irar kuma yana sa LED ta fitar da haske.

12. Trends na Fasaha

Yanayin nunin lambobi yana ci gaba zuwa ga ingantaccen inganci, ƙarancin amfani da wutar lantarki, da ingantaccen karantawa. Fasahar AlInGaP tana wakiltar muhimmin mataki sama da tsofaffin kayan. Ci gaba na gaba na iya haɗawa da ƙananan faɗuwar wutar lantarki, haɗakar da ICs masu tuƙi a cikin fakitin don hanyoyin haɗin \"direct-microcontroller\", da kuma amfani da sabbin kayan don launuka daban-daban ko faɗin kewayon zazzabi. Bukatar kayan aiki masu ingantaccen amfani da makamashi a cikin na'urorin da ake ɗaukuwa da na IoT suna tabbatar da dacewar nunin masu inganci, ƙaramin wutar lantarki kamar LTD-6710JD.
