9. Tambayoyin da Ake Yawan Yi (Dangane da Ma'auni na Fasaha)

Q: Zan iya tuƙa wannan jerin LED kai tsaye daga wadataccen dabaru na 5V ko 3.3V?

A: A'a. Dole ne ku yi amfani da resistor mai iyakance halin yanzu. Misali, tare da wadataccen 5V da V na yau da kullun_Fna 2.0V a 20mA, resistor na jerin da ake buƙata shine R = (5V - 2.0V) / 0.02A = 150 Ω.

Q: Menene bambanci tsakanin nau'ikan SYG da UY?

A: SYG (Brilliant Yellow Green) yana fitar da haske a kololuwar tsawon tsawon ~575nm (kore-rawaya), yayin da UY (Brilliant Yellow) ke fitarwa a ~591nm (rawaya). Bambancin UY kuma yana da mafi girman ƙarfin haske na yau da kullun (80 mcd vs. 50 mcd).

Q: Shin wannan samfurin ya dace da aikace-aikacen waje?

A: Kewayon zafin aiki shine -40°C zuwa +85°C, wanda ya ƙunshi yanayin waje da yawa. Duk da haka, na'urar ba ta da ruwa a cikin ta. Don amfani da waje, dole ne a saka ta a cikin akwati mai rufaffiyar da ke kare ta daga danshi da radiation UV, wanda zai iya lalata resin ɗin epoxy bayan lokaci.

Q: Ta yaya zan fassara 'Matsayi' (CAT) akan alamar?

A> Matsayi yawanci suna rarraba LEDs bisa takamaiman ma'auni kamar ƙarfin haske ko ƙarfin lantarki na gaba. Tuntubi cikakken takardar ƙayyadaddun bayanin bin na masana'anta (ba a bayar da shi a cikin wannan ɓangaren ba) don zaɓar daidai matsayi don buƙatun daidaiton aikace-aikacenku.

10. Yanayin Amfani na Aiki

Yanayi: Ƙirar mai nuna cajin baturi mai matakai da yawa don na'urar ɗaukar hoto.

Injiniya na iya amfani da fasalin da za'a iya tattarawa na wannan jerin LED. Don mai nuna mataki 5, ana iya amfani da wuraren LED guda biyar a cikin jeri ko jeri biyar a tsaye/a kwance. Kowane mataki direba ne ta hanyar da'irar kwatancen da ke sa ido kan ƙarfin lantarki na baturi. Daidaitaccen tazara da launin da jeri ke bayarwa yana tabbatar da nuni na ƙwararru da karantacce. Ƙarancin amfani da wutar lantarki yana da mahimmanci ga na'urorin da ake amfani da baturi. Ƙirar za ta haɗa da ƙididdige masu iyakance halin yanzu da suka dace don kowane LED bisa ƙarfin lantarki na da'irar direba da kuma tabbatar da jimillar halin yanzu da ake ɗauka daga baturi yayin nuna alama yana cikin iyakokin da aka yarda da su.

11. Gabatarwar Ka'idar Aiki

Diodes masu fitar da haske (LEDs) na'urorin semiconductor ne waɗanda ke fitar da haske lokacin da wutar lantarki ta wuce ta cikin su. Ana kiran wannan al'amari electroluminescence. Lokacin da aka yi amfani da ƙarfin lantarki na gaba a kan haɗin gwiwar p-n na kayan semiconductor (AlGaInP a wannan yanayin), electrons suna sake haɗuwa tare da ramuka a cikin na'urar, suna sakin makamashi a cikin nau'in photons. Takamaiman tsawon tsawon (launi) na haske an ƙaddara shi ta hanyar tazarar band na makamashi na kayan semiconductor. Mai riƙe na filastik (jeri) yana aiki ne a matsayin mai ɗaukar injiniya da haɗin gwiwar lantarki, yana ba da damar hawa da wayoyi da sauƙi ga guntuwar LED guda ɗaya da yawa.
