Inkungu nemvula zixhaphakile. Kule meko ephantsi ebonakalayo, ukuqhuba okanye ukuhamba endleleni kunokuba nzima kubaqhubi nabahamba ngeenyawo, kodwa iteknoloji yokukhanyisa i-LED yanamhlanje inika abahambi ukuhamba okukhuselekileyo.
Ukukhanya kwendlela ye-LEDngumthombo wokukhanya okuqinileyo welizwe, oneempawu zokukhuselwa kwendalo, akukho ngcoliseko, ukusetyenziswa kwamandla aphantsi, ukusebenza kakuhle kokukhanya, kunye nobomi obude. Ke ngoko, ukukhanya kwendlela ye-LED kuya kuba lolona khetho lulungileyo lokulungiswa kokugcina umbane kwizibane zendlela. Ukukhanya kwendlela ye-LED ngumthombo wokukhanya we-slid-state osebenza kakuhle kakhulu osekelwe kwi-semiconductor pn junction, enokukhipha ukukhanya ngamandla ombane abuthathaka. Phantsi kombane othile othambekele kwicala elifanelekileyo kunye nenaliti yangoku, imingxuma efakwe kwi-p-region kunye nee-electron ezifakwe kwi-n-region zisasazeke kummandla osebenzayo emva kokudityaniswa kwakhona kwemitha kunye nokukhupha iifotoni, ukuguqula ngokuthe ngqo amandla ombane kumandla okukhanya.

Izinto eziluncedo zokukhanya kwendlela ye-LED kwinkungu kunye nemvula inokubonakaliswa kwimiba emithathu:
1. Umkhombandlela wendalo wesibane esikhutshwayo;
2. Iimpawu ze-Wavelength ze-LED ezimhlophe;
3. Ubuninzi bobu bude bobude xa kuthelekiswa neminye imithombo yokukhanya.
Umahluko phakathi kokukhanya kwe-LED kunye nayo yonke eminye imithombo yokukhanya yi-wavelength elawulayo apho ikhupha khona amandla, kunye nendlela amaconsi amanzi adibana ngayo okanye achaphazela i-beam kuloo wavelength, ngakumbi njengoko ubukhulu bamathontsi amanzi buguquka.
Imithombo yokukhanya eyona nto ikhupha amandla okukhanya kwi-wavelengths eluhlaza okwesibhakabhaka kwi-spectrum ebonakalayo, efana ne-LEDs, yenza ngcono kuneminye imithombo yokukhanya kwiimeko ezisezantsi ezibonakalayo.
Ukukhanya kwingingqi ye-violet ye-spectral range inamaza amafutshane kunokukhanya kummandla obomvu. Amasuntswana omphunga wamanzi kwiatmosfera aqhele ukudlula ukukhanya kuluhlu olutyheli-orenji-bomvu, kodwa athanda ukusasaza ukukhanya okuluhlaza. Oku kusenokuba ngenxa yokuba amasuntswana amanzi ngokubanzi afana namaza aluhlaza. Ngoko ke, xa isibhakabhaka sicacile emva kwemvula okanye umoya ucacile ekwindla (kukho amasuntswana amancinci amancinci emoyeni, ngokukodwa ukusabalalisa i-molecular), phantsi kwefuthe elinamandla lokusasazeka kweemolekyuli ze-atmospheric, ukukhanya okuluhlaza okwesibhakabhaka kuyahlakazeka ukuzalisa isibhakabhaka. kwaye isibhakabhaka sibonakala siluhlaza. Le nto yaziwa ngokuba yiRayleigh ukusasazeka.
Kwiimeko ezisezantsi zokubonakala, amasuntswana amanzi akhula ngobukhulu ukuya kwindawo apho awasafani nobukhulu bokukhanya okuluhlaza okwesibhakabhaka. Kweli nqanaba, zithelekiseka ngobukhulu kunye nobude obubomvu-orenji-orenji. Amasuntswana amanzi athanda ukusasazeka kwaye acinezele ukukhanya kula mabhanti, kodwa adlule ukukhanya okuluhlaza okwesibhakabhaka. Yiyo loo nto ukukhanya kwelanga ngamanye amaxesha kunokuvela bluish okanye luhlaza ngenxa yenkungu.
Ukusuka kubungakanani bamasuntswana amanzi ukuya kwi-wavelength, izibane zendlela ze-LED zizona zikhethwa kakhulu kwiimeko zokubonakala eziphantsi. Ubushushu bombala kunye noyilo lokukhanyisa lwenza ezona meko zilungileyo zendlela ngexesha lemvula kunye nenkungu. Ngokuphucula ukubonakala, izibane zendlela ze-LED zigcina iindlela zikhuselekile kwiimvula zemvula kunye neendawo ezinenkungu.
Ukuba unomdla ekukhanyeni kwendlela ye-LED, wamkelekile ukuba uqhagamshelane nomvelisi wokukhanya kwendlela ye-LED TIANXIANG kuFunda ngokugqithisileyo.
