9. Tambayoyin da ake yawan yi Dangane da Ma'auni na Fasaha

Q: Wane ƙimar resistor yakamata in yi amfani da shi tare da wadataccen 5V?

A: Ta amfani da Dokar Ohm (R = (V_wadata- V_F) / I_F) da matsakaicin V_Fna 2.1V a 20mA, R = (5 - 2.1) / 0.02 = 145 Ohms. Daidaitaccen resistor na 150 Ohm shine madaidaicin farawa. Koyaushe tabbatar da ainihin wutar lantarki a cikin da'ira.

Q: Zan iya tuƙa wannan LED a 30mA don ƙarin haske?

A: A'a. Matsakaicin ci gaba na DC na gaba shine 20 mA. Wuce wannan ƙimar yana haifar da haɗarin lalacewa na dindindin ga na'urar kuma yana keta ƙayyadaddun yanayin aiki.

Q: Ƙarfin haske yana da faɗi mai yawa (240-1150 mcd). Ta yaya zan tabbatar da daidaiton haske?

A: Yi amfani da tsarin binning. Ƙayyade buƙatun kwandon ƙarfin haske (JK, LM, ko NP) lokacin yin oda don samun LED ɗin a cikin kewayon aiki mai matsi. Ana yiwa alama lambar bin akan jakar tattarawa.

Q: Shin ana buƙatar kariya daga ƙarfin lantarki na baya?

A: Duk da cewa na'urar na iya jure har zuwa 5V a baya, ba a tsara ta don aikin baya ba. A cikin da'irori inda ƙarfin lantarki na baya zai yiwu (misali, haɗin AC, kayan aiki masu jan hankali), ana ba da shawarar kariya ta waje kamar diode a layi daya (cathode zuwa anode).

10. Lamarin Aikace-aikace na Aiki

Yi la'akari da zanen bangon nuna matsayi don na'urar hanyar sadarwa ta cibiyar sadarwa tare da alamun LED goma iri ɗaya na amber. Don tabbatar da daidaiton haske, kowace LTL1NHSJ4D LED yakamata a tuƙa ta daban daga filin GPIO na microcontroller na 3.3V. Ana sanya resistor na jere na kusan 62 Ohms ((3.3V - 2.1V) / 0.02A = 60 Ohms, mafi kusancin ƙimar daidaitaccen 62 Ohms) akan layin anode na kowane LED. Ana hawa LED ɗin akan PCB tare da igiyoyin da aka ƙirƙira 4mm daga jiki don dacewa da kaurin bangon waya. Yayin haɗawa, ana bin ƙa'idodin ESD, kuma ana yin gishiri tare da ƙarfen da aka saita zafinsa zuwa 320°C na dakika 2 a kowane haɗin gwiwa. Ta hanyar ƙayyade kwandon ƙarfin haske na LM (400-680 mcd), ana samun daidaitaccen bayyanar matsakaicin haske a duk alamomi goma.

11. Gabatarwar Ka'ida

Wannan LED yana aiki bisa ka'idar electroluminescence a cikin diode semiconductor. Yankin aiki ya ƙunshi Aluminum Indium Gallium Phosphide (AlInGaP). Lokacin da aka sanya ƙarfin lantarki na gaba, ana shigar da electrons da ramuka cikin yankin aiki inda suke sake haɗuwa, suna sakin makamashi a cikin nau'in photons. Takamaiman abun da ke cikin gawa na AlInGaP yana ƙayyade makamashin bandgap, wanda kuma ya ayyana tsayin zango na fitar da haske, a wannan yanayin, amber/rawaya. Kayan ruwan tabarau da aka watsa suna watsa hasken, suna haifar da tsarin kallo mai faɗi, mafi daidaito idan aka kwatanta da ruwan tabarau mai tsabta.

12. Trends na Ci Gaba

Gabaɗayan yanayin a LED na nuna alama yana ci gaba zuwa mafi inganci (lumens da yawa kowace watt), wanda ke ba da damar fitar da haske iri ɗaya a ƙananan gudun wutar lantarki, rage amfani da wutar lantarki da samar da zafi. Hakanan ana mai da hankali kan inganta daidaiton launi da kwanciyar hankali akan zafin jiki da tsawon rai. Duk da yake kunshin hawa ta rami ya kasance sananne don ƙirƙira samfuri, haɗawa da hannu, da wasu aikace-aikacen masana'antu, kunshin na'urar hawa saman (SMD) suna ƙara rinjaye a cikin kera mai yawa, mai sarrafa kansa saboda ƙaramin girmansu da ƙaramin bayyanarsu. Fasahar kayan AlInGaP na asali ta balaga kuma tana ba da kyakkyawan aiki don launuka ja, orange, da amber.
