Inkungu nemibukiso kuvamile. Kulezi zimo ezibonakala eziphansi, ukushayela noma ukuhamba emgwaqweni kungaba nzima kubashayeli nakwabahamba ngezinyawo, kepha ubuchwepheshe besimanje bokukhanyisa umgwaqo oholwa yi-LED.
Isibani somgwaqo we-LEDUmthombo wokukhanya oqinile oqinile, onezimpawu zokuvikelwa kwemvelo, akukho ukungcoliswa komhlaba, ukusetshenziswa kwamandla okuphansi, ukusebenza kahle okukhanyayo okukhanyayo, kanye nokuphila okude. Ngakho-ke, ukukhanya komgwaqo we-LED kuzoba yisinqumo esihle kakhulu sokulungiswa kabusha kwamandla kokukhanya komgwaqo. I-LED Road Light ingukusebenza okuphezulu komthombo wokukhanya okuqinile okusekelwe ku-semiconductor pn Jewncy, ongakhipha ukukhanya ngamandla kagesi abuthakathaka. Ngaphansi kwe-voltage ethile ye-bias ye-BIAS ne-BASH TRELTAGE, izimbobo ezifakwe esifundeni se-P kanye nama-elektroni afakwe esifundeni se-N asebenzisa isifunda esisebenzayo ngemuva kokubuyiselwa kwemali okusebenzayo kanye nokukhipha ama-photon akhanyayo, aguqule ngokuqondile amandla kagesi abe amandla akhanyayo.

Izinzuzo zokukhanya komgwaqo we-LED enkungceni nemvula zingabonakala ezicini ezintathu:
1. Ukuqondiswa okungokwemvelo kogongolo olukhanyisiwe;
2. Izimfanelo ze-wavelethth ze-LED ezimhlophe;
3. Imvamisa yale wavelength uma iqhathaniswe neminye imithombo yokukhanya.
Umehluko phakathi kokukhanyisa kwe-LED nayo yonke eminye imithombo yokukhanya yi-wavelength evelele lapho ukhipha khona amandla, nokuthi amaconsi wamanzi ahlangana kanjani noma athinta ugongolo khona kulolo usayizi wamaconsi wamanzi.
Imithombo ekhanyayo ekhipha amandla akhanyayo kuma-wavelength aluhlaza okwesibhakabhaka we-spectrum ebonakalayo, njenge-LEDs, yenza kangcono kuneminye imithombo yokukhanya ezimweni ezibonakala phansi.
Ukukhanya esifundeni saseViolet sohlobo olubukhali kunama-wavelength amafushane kunokukhanya esifundeni esibomvu. Izinhlayiya zamanzi emkhathini zivame ukudlula ukukhanya ku-Yellow-Orange-Red Range, kepha zivame ukusakaza ukukhanya okuluhlaza okwesibhakabhaka. Lokhu kungahle kube ngenxa yokuthi izinhlayiya zamanzi zifana ngokuvamile nama-wavelength aluhlaza okwesibhakabhaka. Ngakho-ke, lapho isibhakabhaka sicacile ngemuva kokuthi imvula noma umoya ucacile ekwindla (kukhona izinhlayiya ezimbalwa ezihlanganayo emoyeni, ikakhulukazi ukusakazeka kwamangqamuzana), ngaphansi komphumela oqinile wokuhlakazeka kwama-molecule asemkhathini, ukukhanya okuluhlaza okwesibhakabhaka kuhlakazekile ukugcwalisa isibhakabhaka, Futhi isibhakabhaka sivela luhlaza okwesibhakabhaka. Le nto yaziwa ngokuthi uRayleigh ehlakazeka.
Ezimweni eziphakeme ukubonakala, izinhlayiya zamanzi zanda ngosayizi ukuya ephuzwini lapho zingasafani ngosayizi amagagasi akhanyayo aluhlaza okwesibhakabhaka. Ngalesi sikhathi, ziqhathaniswa ngosayizi kuya kuma-wavelength aphuzi aphuzi. Izinhlayiya zamanzi zivame ukusakaza futhi zicindezele ukuKhanya kula mabhendi, kepha kudlule ukukhanya okuluhlaza okwesibhakabhaka. Kungakho ukukhanya kwelanga kwesinye isikhathi kungavela kalula noma kube luhlaza ngenxa yenkungu.
Kusuka kusayizi wezinhlayiyana wamanzi ku-wavelength, amalambu omgwaqo aholwa yi-LED angukukhetha okungcono kakhulu kwezimo eziphansi zokubonakala. Ukushisa kombala nokuklama okukhanyayo kwakha izimo zomgwaqo ezinhle kakhulu ngesikhathi semvula nenkungu. Ngokwenza ngcono ukubonakala, amalambu omgwaqo aholwa eholwa agcina imigwaqo ephephile emabuthweni emvula kanye nezindawo zenkungu.
Uma unesifiso sokukhanya komgwaqo we-LED, wamukelekile ukuxhumana nomkhiqizi we-LED Road Light Unicxiang toFunda kabanzi.
