Ukulinganisa impilo ye-LED nokuxoxa ngembangela yokwehluleka kokukhanya kwe-LED

Ukusebenza isikhathi esideI-LEDkuzodala ukuguga, ikakhulukazi amandla aphezuluI-LED, inkinga yokubola kokukhanya ibucayi kakhulu. Uma ukala impilo ye-LED, akwanele ukuthatha umonakalo wokukhanya njengendawo yokugcina yokuphila kwesibonisi se-LED. Kubaluleke kakhulu ukuchaza impilo ye-LED eholwa ngamaphesenti ancipha ukukhanya, afana no-5% noma u-10%.

Ukubola okukhanyayo: lapho ushaja ingaphezulu lesigubhu esine-photosensitive, ngokunqwabelana kwenkokhiso ebusweni besigubhu se-photosensitive, amandla nawo ayanda, 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 “ukwehla kokukhanya” futhi yehlisa ijubane ekugcineni.
