Ana samar da abubuwan akan tef mai faɗi 8mm mai ɗaukar kaya wanda aka rufe da tef ɗin murfi, an nade shi akan reels mai diamita inci 7 (178mm). Kowane reel yana ƙunshe da guda 2000. Kunshin ya yi daidai da ƙayyadaddun ANSI/EIA 481. Mafi ƙarancin adadin kunshin na guda 500 ya shafi sauran adadi. An ba da cikakkun girma don aljihun tef da reel.

8. Shawarwarin Aikace-aikace

8.1 Yanayin Aikace-aikace na Yau da Kullun

Wannan LED ya dace da kyau don nuna matsayi a cikin kayan lantarki na masu amfani (wayoyi, kwamfutocin hannu, kayan masarufi), hasken baya na gaban allon da alamomi, da ƙaramin haske na gabaɗaya a cikin alamun. Faɗin kusurwar kallonsa yana sa ya yi tasiri ga aikace-aikacen da ganin daga kusurwoyi da yawa yake da mahimmanci.

8.2 Abubuwan da Ake Yi la'akari da su a Zane

Gudanar da Zafi:Ko da yake ɓarnar wutar lantarki ƙanƙanta ce, tabbatar da isasshen yanki na tagulla na PCB ko ramukan zafi na iya taimakawa wajen kiyaye ƙananan zafin junction, kiyaye fitar da haske da tsawon rai.
Iyakance Halin Yanzu:Koyaushe yi amfani da resistor na jere ko direban halin yanzu na akai-akai wanda aka keɓance ga ƙarfin wutar lantarki da halin yanzu na gaba da ake so (≤30mA).
Kariya ta ESD:Ya kamata a kiyaye matakan kariya na ESD na yau da kullun yayin sarrafawa da haɗawa.
Zane na Gani:Ruwan tabarau "farin haske" yana ba da fitar da haske mai laushi, mai faɗi. Don haske mai mai da hankali ko jagora, ana iya buƙatar na'urorin gani na biyu.

9. Kwatancen Fasaha da Bambance-bambance

Idan aka kwatanta da tsofaffin fasahohin LED, amfani da kayan AlInGaP (Aluminum Indium Gallium Phosphide) don tushen orange yawanci yana ba da ingantacciyar inganci da ingantaccen kwanciyar hankali na zafin jiki na tsinkaya da fitarwa idan aka kwatanta da wasu tsarin kayan don launuka a cikin kewayon ja-orange-amber. Haɗuwa tare da ruwan tabarau mai farin haske yana haifar da bayyanar orange mai daidaito, mai laushi, yana bambanta shi da LEDs na ruwan tabarau masu tsabta waɗanda ke da mafi mai da hankali, mafi ƙarfi.

10. Tambayoyin da Ake Yi Maimaitawa Dangane da Ma'auni na Fasaha

Q: Menene bambanci tsakanin tsayin tsinkaya da tsinkaya mai rinjaye?
A: Tsayin tsinkaya shine tsayin tsinkaya guda ɗaya wanda ƙarfin gani da aka fitar ya fi girma. Tsinkaya mai rinjaye shine tsayin tsinkaya guda ɗ�a na haske mai launi ɗaya wanda ya dace da launin da ake ganin LED idan aka kwatanta da hasken farin tunani. Tsinkaya mai rinjaye ya fi dacewa don ƙayyadaddun launi.

Q: Zan iya tuƙa wannan LED a 30mA akai-akai?
A: Matsakaicin Matsakaici na Cikakken ya ƙayyade 30mA DC a matsayin babban iyaka. Don aiki mai dogaro na dogon lokaci, al'ada ce ta yau da kullun tuƙa LEDs ƙasa da matsakaicin ƙimar su, sau da yawa a 20mA kamar yadda aka yi amfani da shi a cikin yanayin gwaji, don haɓaka tsawon rai da sarrafa tasirin zafi.

Q: Me ya sa ƙayyadaddun halin yanzu na baya yake da mahimmanci idan ba a ƙera na'urar don aikin baya ba?
A: Wannan ƙayyadaddun yana da mahimmanci ne don dalilai na gwaji (gwajin IR) kuma yana nuna halayen ɗigon na'urar. Yana jaddada cewa yin amfani da ƙarfin wutar baya zai iya haifar da halin yanzu ya gudana kuma yana iya lalata LED, don haka dole ne ƙirar da'ira ta hana karkatar da baya.

11. Misalin Zane da Amfani na Aiki

Yanayi: Zanen allon nuna matsayi da yawa.Mai zane yana buƙatar matakan haske daban-daban guda uku (Ƙananan, Matsakaici, Babba) don alamar matsayi orange akan na'urar da ke amfani da layin dogo na 5V. Ta amfani da LED T680KFWT daga kwandon haske na T2 (355-450 mcd), za su iya cimma Babban haske ta hanyar tuƙi a 20mA. Don Matsakaici da Ƙananan, za su iya amfani da daidaitawar faɗin bugun jini (PWM) a mitar da ta isa don guje wa kyan gani (misali, >100Hz) tare da ayyukan aiki na, misali, 50% da 10%, bi da bi. Wannan yana kiyaye daidaiton launi yayin bambanta hasken da ake gani. Ƙimar resistor na jere mai sauƙi za a ƙididdige ta kamar R = (5V - VF) / 0.020A. Ta amfani da VF na yau da kullun na 2.0V (daga bin D2), R = (5-2)/0.02 = 150 ohms. Resistor na 150-ohm, 1/8W zai isa.

12. Gabatarwa kan Ka'idar Aiki

Diodes masu fitar da haske na'urori ne na semiconductor waɗanda ke fitar da haske ta hanyar electroluminescence. Lokacin da aka yi amfani da ƙarfin wutar gaba a kan haɗin p-n, electrons daga yankin n-type da ramuka daga yankin p-type ana shigar da su cikin yankin aiki. Lokacin da waɗannan masu ɗaukar caji suka sake haɗuwa, ana sakin makamashi a cikin nau'in photons. Takamaiman tsinkaya (launi) na hasken da aka fitar an ƙaddara shi ta hanyar ƙarfin bandgap na kayan semiconductor da aka yi amfani da su a cikin yankin aiki. A cikin wannan na'urar, ana amfani da AlInGaP don samar da photons a cikin kewayon tsinkaya orange (~605 nm). Ruwan tabarau na epoxy an cika shi da barbashi masu yadawa don watsa hasken, ƙirƙirar tsarin fitarwa mai faɗi, mafi daidaito.

13. Trends da Ci gaban Masana'antu

Yanayin gabaɗaya a cikin SMD LEDs yana ci gaba zuwa ga ingantaccen inganci na haske (ƙarin fitar da haske a kowace watt na lantarki), ingantaccen daidaiton launi ta hanyar ƙaramin binning, da ingantaccen aminci. Hakanan akwai mayar da hankali kan haɓaka fakitin da zai iya jure yanayin reflow mai zafi da ake buƙata don solder maras gubar da haɗawa tare da sauran abubuwan. Ƙananan ƙira ya kasance babban mai tuƙa, tare da haɗawa da kayan lantarki na sarrafawa. Ka'idojin hasken ƙwaƙƙwaran, gami da inganci da tsawon rai, suna ci gaba da sanya LEDs su zama babbar mafita don aikace-aikacen nuni da haskakawa a duk sassan.
