Idan aka kwatanta da LED marasa matakin mota, babban abin da ya bambanta wannan sashi shine cancantar sa na AEC-Q102 da faɗin kewayon zafin jiki (-40°C zuwa +110°C), waɗanda ke tilas ga aikace-aikacen mota. Ƙimar sa na Ƙarfin Lalle Aji A1 yana nuna ƙarfin juriya ga sulfur da sauran yanayi masu lalata, wani al'amari na gama gari a cikin yanayin mota. Fakitin PLCC-2 yana ba da daidaitaccen ma'auni na girma, iya gyaɗa, da fitar da haske idan aka kwatanta da ƙananan fakitin guntu ko manyan LED na rami.

10. Tambayoyin da ake yawan yi (Bisa Sigogi na Fasaha)

Q: Menene halin yanzu na aiki da aka ba da shawarar?

A: An ba da daidaitaccen yanayin gwaji da aikin yau da kullun a 30 mA. Ana iya sarrafa shi daga 5 mA zuwa matsakaicinsa na 50 mA, amma inganci da tsawon rayuwa suna inganta a ko kusa da halin yanzu na yau da kullun.

Q: Ta yaya zafin jiki ke shafar haske?

A: Kamar yadda aka nuna a cikin lanƙwasa aiki, ƙarfin haske yana raguwa yayin da yanayin zafi na haɗin kai ya tashi. Ingantaccen nutsewar zafi yana da mahimmanci don kiyaye ingantaccen fitar da haske.

Q: Zan iya tuƙa wannan LED da samar da 5V?

A: Ee, amma ana buƙatar resistor na jerin don iyakance halin yanzu. Ƙimar resistor R = (Ƙarfin Lantarki - LED Vf) / Halin Yanzu da ake so. Yi amfani da matsakaicin Vf daga kwandon ko takardar bayanin don ƙira mai ra'ayin mazan jiya.

Q: Menene ma'anar kusurwar kallo na 120°?

A> Yana nufin faɗaɗawar kusurwar inda ƙarfin haske ya kasance aƙalla rabin mafi girman ƙimarsa (wanda aka auna a tsakiya). Yana ba da filin kallo mai faɗi sosai.

11: Nazarin Shari'ar Ƙira mai Aiki

Yi la'akari da ƙirar hasken baya don rukunin maɓalli na mota tare da LED ja iri ɗaya 10. Ƙarfin lantarki na tsarin shine 12V (baturin mota). Don tabbatar da tsawon rayuwa, mun zaɓi tuƙi kowane LED a 25 mA (ƙasa da 30mA na yau da kullun). Da'awar mun yi amfani da LED daga mafi girman kwandon Vf (2.75V matsakaici), resistor na jerin ga kowane LED zai kasance: R = (12V - 2.75V) / 0.025A = 370 Ohms. Daidaitaccen resistor 360 ko 390 Ohm zai dace. Shimfidar PCB za ta haɗa LED ɗin kuma ta haɗa kushin zafinsu zuwa wani zubar da tagulla gama gari don watsar da zafi. Don tabbatar da kamanni iri ɗaya, an ba da shawarar ƙayyade LED daga babban tsayin raƙuman ruwa ɗaya da kwandon ƙarfin haske.

12. Gabatarwar Ka'idar Aiki

Wannan diode ne mai fitar da haske na semiconductor. Lokacin da aka yi amfani da ƙarfin lantarki na gaba wanda ya wuce ƙarfin lantarki na gaba na halayensa (~2V don ja), electrons da ramuka suna sake haɗuwa a cikin yanki mai aiki na guntun semiconductor (yawanci bisa Aluminum Gallium Indium Phosphide - AlGaInP don ja). Wannan tsarin sake haɗawa yana sakin makamashi a cikin nau'in photons (haske). Takamaiman abun da ke ciki da tsarin suna ƙayyade tsayin raƙuman ruwa (launi) na hasken da aka fitar. Fakitin filastik yana rufe kuma yana kare guntun, yana haɗa leadframe don haɗin lantarki, kuma ya haɗa da ruwan tabarau da aka ƙera wanda ke siffantar fitar da hasken haske.

13. Trends na Fasaha

Gabaɗayan yanayin a cikin LED na SMD kamar wannan yana zuwa ga ƙarin inganci (ƙarin fitar da haske a kowace watt na shigar da lantarki), wanda ke rage amfani da wutar lantarki da kayan aikin zafi. Hakanan akwai ƙoƙarin ƙara aminci da tsawon rayuwar aiki, musamman ga aikace-aikacen mota da masana'antu. Ƙananan fakitin yana ci gaba, amma PLCC-2 ya kasance sananne saboda ingantaccen ma'auni na aiki, farashi, da sauƙin haɗawa. Bugu da ƙari, haɗa fasaloli kamar ingantaccen ƙa'idar halin yanzu ko diode na kariya a cikin fakitin wani yanayi ne mai girma don sauƙaƙe ƙirar da'ira.
