Inkungu kunye nemiboniso ixhaphakile. Kwezi meko zibonakalayo ezibonakalayo, ukuqhuba okanye ukuhamba kwindlela kunokuba nzima kubaqhubi nabahambi ngeenyawo, kodwa itekhnoloji yokukhala kwendlela yendlela ibonelela ngoohashe abahamba ngokukhuselekileyo.
Ukukhanya kwendlela ye-LEDNgumthombo wokukhanya oqinileyo obandayo, oneempawu zokukhusela isisingqongileyo, akukho longcoliseko, ukusetyenziswa kwamandla ophantsi, ukusebenza okuphezulu okuphezulu, kunye nobomi obude. Ke ngoko, ukukhanya kwendlela ekhokelwayo kuya kuba yeyona ndlela ilungileyo ekuhlaziyweni okusindisa amandla okukhanya kwendlela. Ukukhanya kwendlela ye-LED kukusebenza kakuhle komthombo wokukhanya oqinileyo olwenziwe kwi-semiconductor pn junction, onokukukhanya ngamandla ombane abuthathaka. Ngaphantsi kwe-biest ethile eyakhayo kunye nenaliti yangoku, imingxunya enamathele kwingingqi ye-p kunye ne-electroni igcinwe kwingingqi ye-N-Ingingqi ye-N-Indawo yokuBuyisela iMveliso emva kokubuyela komgangatho kwaye iguqula i-finnel mandla.

Izibonelelo zokuKhanya kwendlela e-LED kwinkungu kunye nemvula zinokubonakala kwimiba emithathu:
1. Ulwalathiso lwemvelo lwe-Beam ekhutshiwe;
2. Iimpawu zezinto ezimhlophe ze-LED;
I-3. Ukuhamba rhoqo kwala manzi xa kuthelekiswa neminye imithombo yokukhanya.
Umahluko phakathi kokukhanya kwe-LED kwaye yonke eminye imithombo yokukhanya yeyona ndawo ikhupha amanzi, kwaye iimpuphu zamanzi zisebenzisana njani okanye zichaphazela njani umngxunya wemigangatho yamanzi.
Imithombo yokukhanya ethatyathwa ngamandla amakhulu kumaza aluhlaza okwesibhakabhaka esibonakalayo, njengokukhutshelwa, senze okungcono kunezinye imithombo yokukhanya kwiimeko ezibonakalayo.
Ukukhanya kwingingqi ye-violet yoluhlu olubonakalayo lunemigangatho emifutshane kunokukhanya kwingingqi ebomvu. Amanzi amasuntswana asemanzini akwimo yezulu idla ngokudlula ukukhanya kwi-tyheli-orenji-ebomvu, kodwa badla ngokusasaza ukukhanya okuluhlaza. Oku kunokuba ngenxa yokuba amasuntswana asenzi afanayo nawo amazaqanda aluhlaza. Ke ngoko, xa izulu licacile emva kwemvula okanye umoya lucacile e-Autumn (kukho iziphumo ezibini ezikhoyo emoyeni), ukukhanya kwe-molekring), ukukhanya okuluhlaza okwesibhakabhaka kusasazeke ukugcwalisa isibhakabhaka, Kwaye isibhakabhaka sibonakala siluhlaza. Le phenonon yaziwa ngokuba kukusasazwa kweRanyaigh.
Kwiimeko eziphantsi zokubonakala, amasuntswana amanzi anyuka ngobukhulu ukuya kwinqanaba apho bengasabi njalo ngokobukhulu be-Blue CHEAVECS. Ngeli xesha, zithelekiswa nobungakanani kwi-Yellow-orenji-Red Waveleths. Amasuntswana amanzi athanda ukusasaza kwaye acinezele ukukhanya kwezi ntlobo, kodwa adlulise ukukhanya oluhlaza okwesibhakabhaka. Kungenxa yoko le nto ukukhanya kwelanga ngamanye amaxesha kubonakala bluish okanye luhlaza ngenxa yenkungu.
Ukusuka kubungakanani bamanzi ukuya kwi-wavelength, izibane zendlela ezikhokelwe zezona zikhetho zilungileyo kwiimeko eziphantsi zokubonakala. Iqondo lobushushu kunye noyilo lokukhanyisa Yenza ezona meko zibalaseleyo zemvula ngexesha lemvula nenkungu. Ngokuphucula ukubonakala, izibane zendlela ezikhokelwe zigcina iindlela zikhuselekile kwimidlalo yemvula kunye neendawo ezinenkuni.
Ukuba unomdla wokukhanya kwendlela ye-LED, wamkelekile ukunxibelelana nayeFunda ngokugqithisileyo.
