• Fasahar Kayan:Amfani da AlInGaP don ja yana ba da inganci mai girma da kyakkyawan kwanciyar hankali na zafin jiki, yayin da InGaN don kore ke ba da fitarwa mai haske a cikin bakan gani.
• Fitarwa ta gefe:Ba kamar LED masu fitarwa na sama ba, wannan fakitin yana jagorantar haske a gefe, wanda shine mahimmin siffa don takamaiman aikace-aikacen hasken baya da alamomi inda ake buƙatar sarari a tsaye ko takamaiman kusurwar dubawa.

10. Tambayoyin da ake yawan yi (FAQs)

Q1: Menene bambanci tsakanin tsayin tsayin tsayi da tsayin tsayin tsayi?
A1: Tsayin tsayin tsayi (λ_P) shine tsayin tsayi guda ɗaya wanda bakan fitarwa yake da matsakaicin ƙarfinsa. Tsayin tsayin tsayi (λ_d) shine tsayin tsayi guda ɗaya na hasken monochromatic wanda, lokacin da aka haɗa shi da takamaiman tunani na fari, ya dace da launin da LED ke gani. λ_dyana da alaƙa da fahimtar launi na ɗan adam.

Q2: Shin zan iya tuƙa guntu ja da kore a lokaci guda a matsakaicin halin yanzu na DC?
A6: A'a. Matsakaicin Matsakaicin Kimantawa ya ƙayyade iyakokin ɓarnawar wutar lantarki ga kowane guntu da kansa (Ja: 50 mW, Kore: 38 mW). Tuƙi duka a matsakaicin halin yanzu (Ja 20mA @ ~2.3V = 46 mW, Kore 10mA @ ~3.5V = 35 mW) zai yiwu ya wuce iyakar iyakar zafin jiki na fakitin idan an ci gaba da shi, mai yiwuwa ya haifar da zafi da rage rayuwa. Rage halin yanzu ko aiwatar da sarrafa zafin jiki don aiki biyu a babban wutar lantarki.

Q3: Me ya sa buƙatun danshi na ajiya ya fi tsauri bayan an buɗe jakar?
A3: Jakar da aka rufe tana ɗauke da busassun abu kuma shinge ne na danshi. Da zarar an buɗe, fakitin SMD na iya ɗaukar danshi daga iska. Yayin solder na sake kwarara, wannan danshin da aka kama zai iya faɗaɗa cikin sauri ("tasirin gwangwani"), yana haifar da rabuwar ciki ko fashewar fakitin. Matsayin MSL 3 yana ba da umarnin "rayuwar bene" da buƙatun gasa don hana wannan.

Q4: Ta yaya zan fassara lambobin kwandon shara lokacin yin oda?
A4: Lambar sashi yawanci tana haɗa da lambobin kwandon shara don ƙarfin haske da wani lokacin tsayin tsayi. Dole ne ku ƙayyade buƙatun hasken ku (misali, Kore a cikin kwandon shara R1 don mafi girman fitarwa) da launi (misali, Kore a cikin kwandon shara AP don takamaiman launin kore) don tabbatar da cewa kuna karɓar abubuwan da suka dace da buƙatun daidaiton haske da bayyanar launi na aikace-aikacenku.
