9. Tambayoyin da Ake Yawan Yi (FAQ)

Q: Menene ƙarfin lantarki na aiki da aka ba da shawarar don wannan LED?

A: Daidaitaccen yanayin gwaji da wurin aiki na yau da kullun shine 20mA DC. Kada ya wuce 25mA akai-akai.

Q: Zan iya tuka wannan LED da samar da wutar lantarki 5V?

A: Ba kai tsaye ba. Tare da Vf na yau da kullun na 3.3V a 20mA, ana buƙatar resistor na jerin. Ƙimar za a iya ƙididdige shi azaman R = (Ƙarfin Wutar Lantarki - Vf) / If. Don samar da wutar lantarki 5V: R = (5V - 3.3V) / 0.02A = 85 ohms. Yi amfani da ƙimar daidaitaccen daidaitaccen (misali, 82 ko 100 ohms) kuma duba sakamakon ƙarfin lantarki.

Q: Ta yaya zan gane anode da cathode?

A: Don fitilar LED na radial na yau da kullun, mafi tsayin jagora shine anode (+). Sau da yawa, gefen cathode (-) na ruwan tabarau na filastik ko flange yana da gefen lebur ko alama.

Q: Shin wannan LED ya dace da amfani a waje?

A: Kewayon yanayin zafin aiki shine -40°C zuwa +85°C, wanda ya ƙunshi yanayi da yawa na waje. Duk da haka, marufi ba shi da ruwa a cikin sa. Don amfani a waje, ƙarin rufewar muhalli (lullubi, ɗakunan ajiya) yana da mahimmanci don kariya daga danshi da gurɓataccen abu.

Q: Me yasa kiyaye nisa na 3mm daga haɗin gini zuwa kwalliya yake da mahimmanci haka?

A: Wannan yana hana wuce gona da iri na zafi daga jagora ya lalata guntu na semiconductor na ciki ko abin rufe epoxy, wanda zai iya haifar da gazawar da ba ta daɗe ba ko duhun ruwan tabarau.

10. Misalin Amfani na Aiki

Yanayi: Ƙirƙirar mai nuna matsayi don na'urar hanyar sadarwa.

LED yana buƙatar bayyananne daga ko'ina cikin ɗaki. Mai ƙira ya zaɓi wannan LED don ƙarfin haske mai girma (2000 mcd). Sun ƙirƙiri PCB tare da sawun da ya dace da zanen marufi. An sanya resistor mai iyakance ƙarfin lantarki na 100-ohm a cikin jerin tare da LED, wanda aka haɗa zuwa filin GPIO na microcontroller na 3.3V. Wannan yana ba da kusan (3.3V - 3.3V)/100Ω = 0mA a ƙananan dabaru da (3.3V - 2.7V)/100Ω = 6mA a babban dabaru (ta amfani da mafi ƙanƙanta Vf), wanda yake da aminci kuma yana da isasshen haske. Yayin haɗawa, layin samarwa yana amfani da ƙayyadaddun bayanin ginin wave. Ƙunƙuntacciyar kusurwar kallo na 20° ta cika, kamar yadda ta haifar da haske mai haske, mai mai da hankali da aka nufa ga mai amfani, ko da a cikin ɗaki mai haske.

11. Gabatarwa kan Ƙa'idar Aiki

Wannan diode ne mai fitar da haske (LED), na'urar photonic semiconductor. Tsakiyarsa ita ce guntu da aka yi da kayan InGaN. Lokacin da aka yi amfani da ƙarfin lantarki na gaba (wanda ya wuce ƙarfin lantarki na gaba Vf), ana shigar da electrons da ramuka a kan haɗin p-n semiconductor. Lokacin da waɗannan masu ɗaukar caji suka sake haɗuwa, suna sakin makamashi a cikin nau'in photons (haske). Takamaiman tsinkaya (shuɗi, 470 nm) ana ƙaddara shi ta hanyar makamashin bandgap na tsarin kayan InGaN. Abin rufe epoxy mai tsabta kamar ruwa yana kare guntu, yana aiki azaman ruwan tabarau don siffantar fitar da haske (ƙirƙirar kusurwar kallo na 20°), kuma yana haɓaka fitar da haske daga semiconductor.

12. Trends na Fasaha da Mahallin

LED shuɗi dangane da fasahar InGaN suna wakiltar cikakken nasara a cikin hasken ƙwaƙƙwaran jiki. Haɓaka ingantattun LED shuɗi ya ba da damar ƙirƙirar LED fari (ta haɗa shuɗi tare da phosphors rawaya) da cikakkun nuni na RGB. Trends na yanzu a cikin fasahar LED suna mai da hankali kan ƙara inganci (lumens kowace watt), inganta ma'anar launi (CRI) don hasken fari, cimma mafi girman yawan wutar lantarki don hasken gabaɗaya, da haɓaka ƙananan hanyoyin da aka haɗa (kamar micro-LEDs). Wannan takamaiman ɓangaren ya dace da rukunin daidaitaccen, mai aminci, LED mai nuna matsakaicin ƙarfi, ɓangaren aiki wanda ainihin fasaharsa ta balaga kuma an yi amfani da ita a ko'ina cikin masana'antar lantarki.
