7. Abubuwan Tunani na Ƙira da Tambayoyin da Ake Yi (FAQs)

7.1 Ta yaya zan zaɓi resistor mai iyakancewa daidai?

Yi amfani da Dokar Ohm: R = (Vsupply - Vf_LED) / If. Misali, tare da samar da 5V, matsakaicin Vf na 2.0V, da kuma If da ake so na 20mA: R = (5V - 2.0V) / 0.020A = 150 Ω. Koyaushe yi amfani da matsakaicin Vf daga takardar bayanin (2.4V) don ƙirar ra'ayin mazan jiya don tabbatar da cewa halin yanzu bai wuce ƙimar da ake so ba: R_min = (5V - 2.4V) / 0.020A = 130 Ω. Daidaitaccen resistor 150 Ω zai zama zaɓi mai dacewa, yana ba da tsakanin 17.3mA da 20mA dangane da ainihin Vf na LED.

7.2 Zan iya tuƙi wannan LED ba tare da resistor ba?

A'a. Haɗa LED kai tsaye zuwa tushen wutar lantarki ba a ba da shawarar ba saboda yana ƙoƙarin jawo halin yanzu wanda kawai iyakance ta hanyar juriyarsa da tushen, wanda zai iya wuce matsakaicin ƙima kuma ya lalata na'urar nan take.

7.3 Menene bambanci tsakanin tsawon tsawon tsawon da tsawon tsawon tsawon?

Tsawon Tsawon Tsawon (λp)shine tsawon tsawon tsawon guda ɗaya wanda rarraba ikon bakan na hasken da aka fitar ya fi girma.Tsawon Tsawon Tsawon (λd)ƙima ce da aka samo daga zanen launi na CIE wanda ke wakiltar launin hasken da aka gane a matsayin tsawon tsawon guda ɗaya. Don LEDs masu launi ɗaya kamar wannan rawaya, λp da λd sau da yawa suna kusa amma ba iri ɗaya ba. λd ya fi dacewa don ƙayyadaddun launi a aikace-aikace.

7.4 Ta yaya kusurwar kallo ke shafar aikace-aikacena?

Kusurwar kallo na digiri 50 yana ba da tsarin haske mai faɗi, mai watsewa. Wannan yana da kyau ga alamomin matsayi waɗanda ke buƙatar ganin su daga faɗin wuraren kallo. Don aikace-aikacen da ke buƙatar katako mai mai da hankali, ruwan tabarau tare da kusurwar kallo mai ƙuntatawa zai fi dacewa.

8. Kwatancen Fasaha da Matsayi

LTL17KSL5D ya sanya kansa a matsayin LED mai nuna alama na rawaya, mai aminci. Babban bambance-bambancensa sun haɗa da ingantaccen tsarin rarrabuwa don haske da daidaiton launi, cikakkun matsakaicin ƙima waɗanda ke tabbatar da ingantaccen aiki, da cikakkun gargaɗin aikace-aikace waɗanda suka shafi ESD, solder, da sarrafawa. Idan aka kwatanta da LEDs marasa rarrabuwa ko ƙananan ƙayyadaddun bayanai, yana ba masu ƙira babban hasashe a cikin samar da yawa, yana rage haɗarin rashin daidaiton gani a cikin samfuran da aka kammala. Marufin cikin rami yana tabbatar da sauƙin ƙirar ƙira da dacewa da faɗin kewayon ƙirar PCB da ke akwai, yana mai da shi zaɓi mai yawa don sabbin ƙira da kuma kula da samfurin gado.
