Sonke sinokuhlangenwe nakho okunjalo kwempilo. Ezisanda kuthengwaIzibani ze-LEDzihlale zikhanya kakhulu, kodwa ngemva kwesikhathi, izibani eziningi zizoba mnyama futhi zibe mnyama. Kungani izibani ze-LED zinenqubo enjalo?

Ake sikubeke phansi namuhla! Ukuze siqonde ukuthi kungani izibani ze-LED zekhaya lakho ziba lufifi, sidinga ukuqonda igama elichwepheshile – ukubola kokukhanya kwe-LED.

Uma kusetshenziswa izibani eziningi ze-LED, ziba mnyama kakhulu ngoba izibani ze-LED zizobola.

Ukunciphisa ukukhanya kweIsibani se-LEDimikhiqizo iyisignali eyenza buthakathaka ukukhanya ekudluliseni. Njengamanje, i-light attenuation degree yeImikhiqizo ye-LEDeyenziwe ngabakhiqizi abakhulu be-LED emhlabeni ihlukile. I-high power led nayo inokunciphisa ukukhanya, okuhlobene ngokuqondile nezinga lokushisa, ikakhulukazi elinqunywe yi-chip, i-phosphor kanye nobuchwepheshe bokupakisha. Njengamanje, ukubola okukhanyayo kwe-LED emhlophe emakethe kungenye yezinkinga ezibaluleke kakhulu ekuthuthukisweni kokukhanya komphakathi.

Ukubola kokukhanya ngokuvamile kubhekisela ekuguquguqukeni kwayo okukhanyayo. Lapho ishaja ingaphezulu lesigubhu se-photosensitive, ngokunqwabelana kokushaja ebusweni besigubhu esizwelayo, amandla ayanda ngokuqhubekayo, futhi ekugcineni afinyelele amandla "e-saturation", okungamandla aphezulu kakhulu. Amandla angaphezulu azokwehla ngokuhamba kwesikhathi. Ngokuvamile, amandla okusebenza aphansi kunaleli khono. Inqubo yokuthi amandla ayancipha ngokwemvelo ngokuhamba kwesikhathi ibizwa ngokuthi inqubo "yokubola okumnyama". Lapho isigubhu se-photosensitive siskenwa futhi sivezwa, amandla wendawo emnyama (indawo engaphezulu ye-photoconductor engakhanyiswa ukukhanya) isaqhubeka nokubola okumnyama; Esifundeni esikhanyayo (ubuso be-photoconductor bukhanyisa ukukhanya), ukuminyana kwenkampani yenethiwekhi kungqimba lwe-photoconductive kukhula ngokushesha, i-conductivity ikhula ngokushesha, futhi i-voltage ye-photoconductive iyakhiwa, ukushaja kuyanyamalala ngokushesha, kanye namandla angaphezulu kwe-photoconductor nawo. kuncipha ngokushesha. Kubizwa ngokuthi “ukubola okukhanyayo”.
