5.2.1 Abubuwan Ƙira

• Iyakance Halin Yanzu:Koyaushe yi amfani da resistor na jerin don kowane sashi ko anode gama gari don iyakance halin yanzu zuwa ƙimar da aka ƙidaya (misali, 5-10 mA na yau da kullun). Ana ƙididdige ƙimar resistor kamar R = (V_supply - V_F) / I_F.
• Haɗawa:Don nunin lambobi da yawa ta amfani da abubuwa masu kama da juna, ana iya amfani da haɗawa ta rarraba lokaci don sarrafa lambobi da yawa tare da ƙananan fil ɗin tuƙi. Tabbatar cewa matsakaicin halin yanzu a cikin aikin haɗawa bai wuce matsakaicin matsakaicin matsayi ba.
• Kariya ta ESD:Haɗa diodes na kariya na ESD akan layukan shigarwa idan nuni yana cikin yankin da mai amfani zai iya isa, ban da matakan kulawa yayin haɗawa.

6. Kwatancen Fasaha da Trends

6.1 Ka'idar Aiki

Na'urar tana aiki akan ka'idar electroluminescence a cikin haɗin gwiwar p-n na semiconductor. Lokacin da aka yi amfani da ƙarfin wutar lantarki na gaba wanda ya wuce kofa na diode (V_F), electrons da ramuka suna sake haɗuwa a cikin yanki mai aiki na guntun InGaN, suna sakin makamashi a cikin nau'in photons (haske). Substrate na sapphire yana samar da tushe mai tsayayye, lattice-daidaitacce don girma manyan yadudduka na InGaN masu inganci waɗanda suke da mahimmanci don fitar da hasken fari mai inganci, sau da yawa ana samun su ta amfani da guntun LED shuɗi tare da rufi na phosphor.

6.2 Bambance-bambance da Trends

Idan aka kwatanta da tsofaffin fasahohi kamar LED GaAsP ja ko nunin fluorescent na vacuum (VFDs), LED farin InGaN suna ba da ingantaccen inganci, dogon rayuwa, ƙarancin ƙarfin wutar lantarki, da kuma bayyanar zamani. Trend a cikin nunin SMD yana zuwa ga mafi girman yawan pixel (ƙarin sassa ko dot-matrix), ikon launi cikakke (RGB), da haɗawa tare da na'urori taɓawa ko microcontrollers. Koyaya, don sauƙaƙan karantawar lamba, ƙarancin farashi, ingantaccen aminci, nunin sassa na lamba guda kamar LTS-5825SW-P sun kasance masu dacewa sosai saboda sauƙinsu, ingantaccen karantawa, da ingantaccen aikin da aka tabbatar.
