7. Shawarwarin Aikace-aikace da Abubuwan Tsari

7.1 Kewaye na Aikace-aikace na Yau da Kullun

Don amfani da alamar alama ta yau da kullun, ana buƙatar resistor mai iyakancewa mai sauƙi. Ƙimar resistor (R_s) za a iya lissafta ta amfani da Dokar Ohm: R_s= (V_wadata- V_F) / I_F. Inda V_Fshine karfin gaba na yau da kullun (2.0V) kuma I_Fshine karfin gaba da ake so (misali, 20mA). Tabbatar da ƙimar wutar lantarki na resistor ya isa: P_R= (I_F)² * R_s.

7.2 Abubuwan Tsari

• Tuƙin Yanzu:Koyaushe tuƙa LEDs tare da wutar lantarki mai dorewa ko ta amfani da resistor mai iyakancewa. Yin amfani da wutar lantarki mai dorewa daidai da V_Fba a ba da shawarar ba saboda bambancin naúrar zuwa naúrar da dogaron zafi na V_F.
• Gudanar da Zafi:Ko da yake rushewar wutar lantarki yana da ƙasa, tabbatar da isasshen iska a cikin akwati, musamman idan an yi amfani da LEDs da yawa ko kuma idan zafin yanayi ya kusanci matsakaicin matsayi.
• Aiki na Bi-launi/Bi-polar:Fahimtar pinout da tsarin ciki (anode/cathode gama gari don bi-polar, guntu daban-daban don launi biyu) don daidaitaccen tsarin kewaye.
• Kariya ta ESD:Bi ka'idojin gudanar da ESD na yau da kullun yayin haɗawa, kamar yadda LEDs ke da hankali ga fitar da lantarki.

8. Kwatancen Fasaha da Bambance-bambance

339-1 jerin sun bambanta kansu ta hanyar tsarin guntu biyu a cikin kunshin fitila na yau da kullun. Idan aka kwatanta da LEDs guntu guda, yana ba da damar launi biyu ko tsarin bi-polar (kariya ta polarity) a cikin tabo iri ɗaya. Yin amfani da fasahar AlGaInP yana ba da inganci mai girma don tsawon zango ja da kore-rairayi, yana haifar da karfin haske mai kyau (250 mcd don ja, 63 mcd don kore-rairayi) a matsakaicin karfin tuƙi na 20mA. Fadin kusurwar kallo na digiri 25 yana tabbatar da bayyanawa daga mahanga daban-daban, wanda ke da fa'ida ga alamomin panel.

9. Tambayoyin da ake yawan yi (Dangane da Sigogi na Fasaha)

9.1 Menene bambanci tsakanin sigogin SUR da SYG?

SUR yana nuna LED Ja Mai Haske (λ_d~624nm), yayin da SYG ke nuna LED Koren-Rairayi Mai Haske (λ_d~573nm). Sun bambanta a cikin mafi girman tsawon zango da karfin haske na yau da kullun.

9.2 Zan iya tuƙa wannan LED a matsakaicin karfin gaba na 25mA?

Ee, amma halayen lantarki-haske a cikin takardar bayani an ƙayyade su a 20mA. Yin aiki a 25mA zai haifar da fitar da haske mafi girma amma kuma zai ƙara rushewar wutar lantarki da zafin haɗuwa, wanda zai iya shafar dogon lokaci na dogaro da haifar da ɗan canji a cikin tsawon zango. Gabaɗaya kyakkyawan al'ada ne don rage ƙima da yin aiki ɗan ƙasa da matsakaicin matsayi na cikakke don inganta tsawon rayuwa.

9.3 Menene ma'anar "bi-launi" da "bi-polar" ga wannan fitila?

Bi-launi:Kunshin yana ɗauke da guntun LED daban-daban guda biyu (misali, ja ɗaya, kore ɗaya) waɗanda za a iya sarrafa su da kansu. Yawanci suna da jagora uku (cathode ko anode gama gari).
Bi-polar:Kunshin yana ɗauke da guntu LED guda ɗaya amma an gina shi ta yadda zai haskaka lokacin da aka yi amfani da wutar lantarki a kowane polarity (ko da yake mai yiwuwa polarity ɗaya kawai ce daidai don launin da ake nufi). Yana aiki azaman alama mai sauƙi wacce ke haskaka ba tare da la'akari da polarity DC ba, galibi ana amfani da ita a cikin AC ko kewaye marasa la'akari da polarity. Takardar bayani ta ambaci cewa ana samun waɗannan a cikin resin Fari Bayyananne da Launi Bayyananne.

9.4 Yaya mahimmanci ne mafi ƙarancin nisa na 3mm don solder da lankwasa jagora?

Mahimmanci sosai. Resin epoxy wanda ke samar da kwalliyar LED yana da hankali ga zafi da damuwa na injiniya. Solder ko lankwasa kusa da 3mm zai iya canja wurin zafi mai yawa zuwa guntu semiconductor, yana lalata shi, ko kuma ya iya fashe epoxy, yana haifar da gazawa da wuri ko shigar danshi.

10. Tsari na Aiki da Amfani na Aiki

Yanayi: Tsara alamar matsayi biyu don na'urar samar da wutar lantarki.
Mai tsarawa yana buƙatar kayan aiki guda ɗaya don nuna "Jiran Aiki" (rairayi) da "Kunna" (ja) jihohi. Sun zaɓi sigar bi-launi na fitila 339-1. Sun tsara kewaye inda pin microcontroller ke tuƙa cathode na guntu rairayi (SYG) ta hanyar resistor mai iyakancewa don jiran aiki. Wani pin yana tuƙa cathode na guntu ja (SUR) ta hanyar wani resistor daban don matsayin "Kunna". An haɗa anodes na duka guntun tare zuwa layin wadata mai kyau. Kusurwar kallo na 25° tana tabbatar da cewa alamar tana bayyana daga gaban panel. Mai tsarawa ya bi jagororin solder, yana tabbatar da tazarar 3mm, kuma ya ƙayyade daidai tabo na PCB daga girman kunshin. Sun kuma tabbatar da cewa an wuce umarnin ajiya da gudanarwa ga ƙungiyar masana'anta.

11. Gabatarwar Ka'idar Fasaha

Fitilar LED 339-1 tana amfani da kayan semiconductor Aluminum Gallium Indium Phosphide (AlGaInP) don yankin fitar da haske. AlGaInP wani fili ne na semiconductor wanda ƙarfin bandgap sa--don haka launin hasken da aka fitar--za a iya daidaita shi ta hanyar bambance bambancen aluminum, gallium, da indium. Fitowar Ja Mai Haske (~624nm) yana buƙatar wani abun da ya bambanta da fitowar Koren-Rairayi Mai Haske (~573nm). Lokacin da aka yi amfani da wutar gaba wacce ta wuce bakin kunna diode, ana shigar da electrons da ramuka cikin yankin aiki inda suke sake haɗuwa, suna sakin makamashi a cikin nau'in photons (haske). Takamaiman tsawon zango na waɗannan photons an ƙaddara shi ta bandgap na kayan AlGaInP. Ruwan tabarau na epoxy yana aiki don kare guntu semiconductor, siffanta fitarwar haske (kusurwar kallo 25°), da haɓaka fitar da haske.

12. Trends na Masana'antu da Mahallin

Yayin da wannan samfurin ke wakiltar fasahar LED ta cikin rami mai girma, har yanzu yana da dacewa a aikace-aikacen da ke buƙatar babban dogaro, sauƙin haɗawa da hannu, ko takamaiman siffofin injiniya. Trends na masana'antu don fitilu masu nuni a cikin na'urorin lantarki na mabukaci ya fi mayar da hankali zuwa na'urorin LED na saman-mount (SMD) (misali, kunshin 0603, 0402) don haɗawa ta atomatik da ajiyar sarari. Duk da haka, LEDs na cikin rami kamar 339-1 har yanzu ana amfani da su sosai a cikin sarrafa masana'antu, na'urori, da wuraren da ake son mafi kyawun haɗin gwiwar injiniya ko mafi girman fitar haske daga kunshin mafi girma. Ƙarfafa daidaiton muhalli (RoHS, REACH, Ba tare da Halogen ba) da aka gani a cikin wannan takardar bayani shine kai tsaye nunin trends na duniya na dokoki waɗanda ke motsa masana'antar lantarki zuwa kayan aiki da hanyoyin kore.
