Ukuphucula uNyango loMphezulu ngee-UVC ze-LED
Izisombululo ze-UV LEDziye zavela njengenye indlela engabizi kakhulu kwizisombululo zesibane semercury yesiNtu kwiinkqubo ezahlukeneyo zokunyanga. Ezi zisombululo zibonelela ngezibonelelo ezinjengobomi obude, ukusetyenziswa kwamandla aphantsi, ukuthembeka okuphezulu, kunye nokunciphisa ukuhanjiswa kobushushu be-substrate. Nangona kunjalo, imiceli mngeni ihleli ithintela ukwamkelwa okubanzi kokunyangwa kwe-UV LED.
Umceli mngeni othile uvela xa kusetyenziswa ukwakheka kweradical yasimahla kukuba umphezulu wezinto eziphilisiweyo uhlala uncangathi ngenxa yokucinezelwa kweoksijini, nangona umaleko ongezantsi unyangekile ngokupheleleyo.
Enye indlela yokoyisa le ngxaki kukubonelela ngamandla oneleyo e-UVC kuluhlu lwama-200 ukuya kuma-280nm. Iinkqubo zesibane zemercury eziqhelekileyo zikhupha ukukhanya okubanzi ukuze kunyangeke, ukusuka malunga ne-250nm (UVC) ukuya ngaphezulu kwe-700nm kwi-infrared. Lo mboniso ubanzi uqinisekisa ukunyangwa okupheleleyo kwalo lonke uqulunqo kwaye ubonelela ngobude obaneleyo be-UVC ukufezekisa ukunyangwa komphezulu onzima. Ngokwahlukileyo, urhweboIzibane zokunyanga ze-UV LEDokwangoku zilinganiselwe kumaza angama-365nm nangaphezulu.
Kule minyaka mihlanu idlulileyo, ukusebenza kakuhle kunye nobomi bee-UVC LEDs kuphuculwe kakhulu. Ababoneleli be-LED abaninzi baye banikezela ngezixhobo kuphando kunye nophuhliso lwetekhnoloji ye-UVC ye-LED, okukhokelela kwimpumelelo. Ukusetyenziswa okubonakalayo kweenkqubo ze-UVC ze-LED zokunyanga umphezulu kuya kuba nokwenzeka ngakumbi. Ukuqhubela phambili kwitekhnoloji ye-UVC ye-LED yoyise ngempumelelo imiceli mngeni yokunyanga umphezulu eye yathintela ukwamkelwa kwezisombululo ezipheleleyo zokunyanga ze-UV. Xa idityaniswe neenkqubo ze-UVA ze-LED, ukubonelela ngexabiso elincinci le-UVC yokuvezwa kwisithuba sokunyanga akuphumeleli nje kuphela kwindawo engagxiliyo kodwa kunciphisa umthamo ofunekayo. Ukuphumeza izisombululo ezinokwenzeka ze-UVC ngokubambisana nophuculo lokwenziwa kunganciphisa ngakumbi idosi efunekayo ngelixa kunyangwa umphezulu oqinileyo.
Ukuqhubela phambili okuqhubekayo kweteknoloji ye-UVC ye-LED iya kuqhubeka inceda i-UV yokunyanga i-UV njengoko iinkqubo zokunyanga ezisekwe kwi-LED zibonelela ngonyango oluphezulu lomphezulu wokunamathiswa kunye nokwakheka kokugquma. Nangona iinkqubo zokunyanga i-UVC okwangoku zibiza kakhulu kuneendlela zemveli ezisekelwe kwisibane se-mercury, izibonelelo zokonga iindleko zetekhnoloji ye-LED kwimisebenzi eqhubekayo iya kunceda ukoyisa iindleko zezixhobo zokuqala.
