Kusurwar kallon digiri 120 tana ba da tsarin fitarwa mai faɗi, mai yaduwa wanda ya dace da masu nuni na matsayi da haskaka baya inda ake son ganin kusurwa mai faɗi. Don aikace-aikacen da ke buƙatar ƙara mayar da hankali kan katako, za a buƙaci na'urorin gani na biyu (misali, ruwan tabarau ko masu haskakawa). Ruwan tabarau mai tsabta yana rage sha haske, yana ƙara fitarwa daga guntu na AlInGaP.

9. Bayanin Fasaha da Kayan

LTST-M140KRKT yana amfani da kayan semiconductor na Aluminum Indium Gallium Phosphide (AlInGaP) don yankinsa mai fitar da haske. Fasahar AlInGaP ta dace musamman don samar da LED ja, orange, da amber masu inganci. Idan aka kwatanta da tsofaffin fasahohi kamar Gallium Arsenide Phosphide (GaAsP), AlInGaP yana ba da ingantaccen inganci mai haske, mafi kyawun kwanciyar hankali na zafin jiki, da tsawon rayuwar aiki. Ana samar da hasken ta hanyar electroluminescence, inda electrons ke sake haɗuwa da ramuka a cikin yanki mai aiki na semiconductor, suna sakin makamashi a cikin nau'in photons. Takamaiman abun da ke cikin AlInGaP yana aiki don samar da photons a matsakaicin tsawon tsawon da aka yi niyya na 631 nm, wanda idon ɗan adam ke ganinsa azaman haske ja.
