Hali na 1: Hasken Gine-gine:Mai ƙira yana amfani da ƙunƙuntattun kwandon CCT da flux don tabbatar da cewa duk kayan aikin da ke facade na ginin suna da sautin farin iri ɗaya da haske. Tsarin rayuwar "Har Abada" yana tabbatar da samun kayan gyara don kulawa shekaru da yawa bayan haka.

Hali na 2: Hasken Cikin Motoci:Ƙunƙuntattun kwandon ƙarfin lantarki na gaba suna ba da damar sauƙaƙan da'irori masu tushen juriya a cikin LED da yawa a cikin dashboard, suna tabbatar da haske iri ɗaya ba tare da direbobi masu rikitarwa ba, yayin da ƙayyadaddun zafin kayan aikin ke tabbatar da inganci don yanayin zafi mai yawa.

12. Gabatarwar Ka'ida

Diodes masu fitar da haske (LEDs) na'urori ne na semiconductor waɗanda ke fitar da haske lokacin da wutar lantarki ta wuce ta cikin su. Wannan al'amari, wanda ake kira electroluminescence, yana faruwa lokacin da electrons suka sake haɗuwa tare da ramukan electron a cikin na'urar, suna sakin makamashi a cikin nau'in photons. Launin hasken yana ƙaddara ta hanyar tazarar ƙungiyar makamashi na kayan semiconductor. LED farare galibi ana ƙirƙira su ta hanyar amfani da guntun LED shuɗi ko ultraviolet wanda aka lulluɓe da kayan phosphor waɗanda ke canza wasu fitattun haske zuwa tsayin tsayi, wanda ke haifar da farin haske.

13. Trends na Ci gaba

Masana'antar LED na ci gaba da haɓakawa tare da yanayi da yawa bayyananne. Ingantaccen aiki (lumens kowace watt) yana ci gaba da inganta, yana rage amfani da makamashi. Akwai mai da hankali sosai kan haɓaka ingancin launi, gami da mafi girman Fihirisar Nuna Launi (CRI) da mafi daidaiton daidaiton launi. Ƙananan kunshin yayin kiyayewa ko ƙara fitowar haske yana ci gaba. Haɗin kai wani yanayi ne, tare da LEDs suna haɗa direbobi, na'urori masu auna firikwensin, da hanyoyin sadarwa (kamar LED masu kunna IoT). Bugu da ƙari, turawa don dorewa yana rinjayar kayan, hanyoyin masana'antu, da sake yin amfani da su.
