Kungani I-Diode Ekhipha Ukukhanya Imnyama Futhi Imnyama

Wonke umuntu unokuhlangenwe nakho okunjalo kwempilo. Isibani se-LED esisanda kuthengwa sihlala sikhanya ngokukhethekile, kodwa ngemva kwesikhathi esithile, izibani eziningi zizoba mnyama futhi zibe mnyama. Kungani izibani ze-LED zinenqubo enjalo? Ukuze uqonde ukuthi kungani isibani sakho se-LED sizoba mnyama futhi sibe mnyama, kufanele siqale siqonde igama lochwepheshe —— Ubuhlalu besibani se-LED buyehla. Ngemuva kwe-diode ye-tube, ukubola kokukhanya kubhekisela ekutheni ngemva kwesikhathi sokukhanyisa, isilinganiso samandla okukhanya sizoncishiswa futhi asikwazi ukubuyiswa, okungukuthi, ingxenye yokunciphisa ibizwa ngokuthi ukubola kokukhanya kobuhlalu besibani se-LED. Ukukhanya kwe-LED okumnyama kusetshenziswa ngoba ubuhlalu besibani se-LED buzoba nokubola kokukhanya. Ukubola kokukhanya kwemikhiqizo yesibani se-LED kuwubuthakathaka kwesignali yokukhanya ekudluliseni, futhi kulesi sigaba, i-global light-emitting diode abakhiqizi abakhulu benza amazinga ahlukene okubola kokukhanya, kanye ne-high-power light emitting diode nayo inokukhanya. ukubola. Ubudlelwano bunqunywa ikakhulukazi i-chip, impuphu ye-fluorescent kanye nobuchwepheshe bokupakisha. Okwamanje, ukubola kokukhanya kobuhlalu obukhanyayo obumhlophe emakethe kungenye yezinkinga eziyinhloko okufanele simashele ekukhanyeni kwabantu. Ukubola okukhanyayo ngokuvamile kubhekisela ekuguquguqukeni kokukhanya. Lapho ushaja ubuso besigubhu esikhanyayo, njengoba ukushaja kunqwabelana ebusweni besigubhu esizwela ukukhanya, amandla ayaqhubeka nokukhuphuka. “saturation ”Amandla angamandla aphezulu kakhulu. Amandla angaphezulu azokwehla ngokuhamba kwesikhathi. Ngokuvamile, amandla ngesikhathi somsebenzi aphansi kunalawo mandla. Lawa mandla ayancipha ngokwemvelo ngokuhamba kwesikhathi. “Ukubola okumnyama ”Inqubo. Ngesikhathi sokuchayeka kokuskena kwesigubhu esikhanyayo, amandla esifunda esimnyama (ebhekisela endaweni engaphezulu ye-optical conductor engakhanyiswa ukukhanya) asesenqubweni yokubola emnyama; Izinga le-conductivity lakhuphuka ngokushesha, lakha i-voltage ye-optical guide, ukushaja kwanyamalala ngokushesha, futhi amandla angaphezulu e-optical conductor nawo ehla ngokushesha. Shaya ucingo “Ukuhluleka ukukhanya ”I-Essence Lokhu kulapha namuhla.
