[Amapharamitha] Amapharamitha Abalulekile amaningana wobuhlalu besibani be-UVLED

I-UVLED iyithuluzi elikhanyayo le-semiconductor. Njengama-LED asetshenziswa kaningi, umnyombo wawo yi-PN knot. Indlela yokukhipha eyinhloko ukuthi uma ifindo le-PN lengezwa nge-voltage eqondile, amandla efindo le-PN azokwehla. Ngalesi sikhathi, ama-electron endaweni ye-N asakazeka endaweni ye-P, futhi umhume endaweni ye-P usakazeka endaweni ye-N, kodwa inombolo yangaphambili ikude neyokugcina kuneyokugcina. Inkulu kakhulu, ngakho-ke ama-electron azohlanganiswa ngobuningi, futhi amandla akhiqizwa yinhlanganisela akhululwa ngendlela yokukhanya. I-UVLED inala mapharamitha angukhiye alandelayo: 1. I-Wavelength ye-UVLED inobude obuphezulu obubodwa, ibhendi ye-UVA ngokuyinhloko ingu-365nm, 385nm, 395nm, njll. Okulandelayo yishadi le-wavelength elingu-365nm. I-365nm iwubude bayo obuphezulu begagasi. I-Bandwidth, cishe i-360 nm-370 nm. Ubude begagasi be-UVLED buzophinde bukhukhulwe ngezinye izici phakathi nenqubo yokukhanya. Ngokuyinhloko yizici ezimbili: zamanje nezinga lokushisa. Njengoba kuboniswe emfanekisweni, singabona ukuthi ngokwanda kwamanje kanye nezinga lokushisa, i-wavelength izoba nkulu kancane kancane. Ngakho-ke, lapho siklama uhlelo, kufanele sicabangele ngokugcwele inani lamanje kanye nokushisa okusebenzayo kobuhlalu ngesikhathi somsebenzi. Ngokuvamile, sisebenza eduze kwe-wavelength ephezulu. 2. Amandla okubona (amandla afakwe imisebe) Amandla okubona abhekisela ekukhanyeni kobuhlalu besibani. Amaza ahlukene ahlukene ngenxa yokusebenza kahle okuhlukile kokuguqulwa kokukhanya kwe-electro-light. Ngokuvamile, lapho ubude beza beza buba bufishane kubuchwepheshe bamanje, kunciphisa ukuguqulwa kwe-electro -optical. Lapho isikhathi sesikhathi siphansi, siphakama esinye, kulapho i-UVA's LED iphakama kakhulu kune-UVC LED. Okulandelayo ubudlelwano phakathi kwamandla okukhanya namandla e-UVLED ethile: 3. Incazelo ye-VFVF i-Voltage eya phambili, okungukuthi, lapho i-diode iqhutshwa ngokugcwele, i-diode ngokwayo i-PN knot yi-IF. Umehluko we-Voltage. Uma i-VF ye-UVLED ibonakala ngokuvamile, uma kuqhathaniswa ubuhlalu besibani obunamaza ahlukene ahlukene, ubuhlalu besibani be-UVA ngokuvamile bungu-3.5V-3.8V, kanti ubuhlalu besibani be-UVC ngokuvamile bungu-5V-7V. Uma umkhiqizi ofanayo ekhiqiza imikhiqizo efanayo, i-VF ngokuvamile iphatha i-VF, ukuze umkhiqizi wohlelo lokusebenza lwedivayisi ahlukaniswe futhi aphathwe phakathi nesichibi. Ukwengezwa kwamanje ebuhlalu besibani asikho ngesikhathi esifanayo, futhi i-VF yayo nayo iyashintsha. Ngokuvamile, i-current ikhudlwana, i-VF inkulu, njengoba kukhonjisiwe emfanekisweni ongezansi: Umthombo wokukhanya ongaphezulu we-UVLED we-Tianhui usebenzisa ubuhlalu besibani se-UVLED obungenisiwe, imithombo egeleza njalo yekhwalithi ephezulu, ukushabalaliswa kokushisa okuhle kakhulu kuhlanganiswe ne-Design ehle kakhulu yokukhipha ukushisa, ne- izinzuzo zesakhiwo esihlangene, ukwethembeka okuphezulu, nokuzinza okuphezulu. Imikhiqizo yamukelwa kahle ngamakhasimende.
