Njengesizukulwane esisha somthombo wokukhanya, umthombo wokukhanya wephoyinti le-LED usebenzisa umthombo wokukhanya obandayo we-LED eyakhelwe ngaphakathi, ongakhipha imibala ehlukene ngokwezidingo;ngesikhathi esifanayo, ingabuye yakhelwe ngaphakathi kwe-microcomputer chip, ngokulawula uhlelo, ukuze kuzuzwe imiphumela enombala ogcwele njenge-gradient enemibala, ukugxuma, ukuskena, namanzi;futhi Isikrini sokubonisa sokucaciswa okuthile singathathelwa indawo inhlanganisela yohlelo kanye nomumo wamaphikseli womthombo wokukhanya wamaphuzu amaningi, namaphethini ahlukahlukene, umbhalo nokugqwayiza, imiphumela yevidiyo, njll. kungashintshwa;imithombo yokukhanya yephoyinti isetshenziswa kabanzi kakhulu kumaphrojekthi wokukhanyisa indawo yangaphandle.
Imithombo yokukhanya yephoyinti le-LED ihluke kakhulu emisebeni yokushisa evamile kanye nemithombo yokukhanya yokukhishwa kwegesi (njengamalambu e-incandescent, izibani ze-sodium ezinomfutho ophezulu).
Imithombo yamanje yokukhanya kwephoyinti le-LED inezinzuzo ezilandelayo ekukhanyeni:
1. okuhle kokuzamazama komhlaba kanye nokumelana nomthelela
Isakhiwo esiyisisekelo somthombo wokukhanya wephoyinti le-LED ukubeka impahla ye-electroluminescent semiconductor kuhlaka oluholayo, bese uyivala nge-epoxy resin nxazonke.Alikho igobolondo lengilazi esakhiweni.Asikho isidingo sokucofa noma ukugcwalisa igesi ethile eshubhuni njengamalambu e-incandescent noma e-fluorescent.Ngakho-ke, umthombo wokukhanya we-LED unokumelana nokushaqeka okuhle kanye nokumelana nomthelela, okuletha lula ekukhiqizeni, ekuthuthweni nasekusetshenzisweni komthombo wokukhanya we-LED.
2. iphephile futhi izinzile
Umthombo wokukhanya wephoyinti le-LED ungashayelwa i-low voltage DC.Ngaphansi kwezimo ezijwayelekile, amandla kagesi aphakathi kuka-6 no-24 volts, futhi ukusebenza kokuphepha kuba ngcono.Ifaneleka ikakhulukazi ukusetshenziswa ezindaweni zomphakathi.Ngaphezu kwalokho, endaweni engcono yangaphandle, umthombo wokukhanya unokuncisha ukukhanya okuncane kunemithombo yokukhanya evamile futhi unempilo ende.Ngisho noma ivalwa futhi ivaliwe, isikhathi sayo sokuphila ngeke sithinteke.
3. ukusebenza kahle kwemvelo
Ngenxa yokuthi umthombo wokukhanya wephoyinti le-LED awufaki i-mercury yensimbi phakathi nenqubo yokukhiqiza, ngeke ubangele ukungcoliswa kwe-mercury ngemva kokulahlwa, futhi imfucuza yawo ingabuyekezwa kabusha, ilondoloze izinsiza nokuvikela imvelo.
4. isikhathi sokuphendula esisheshayo
Isikhathi sokuphendula sezibani ze-incandescent singama-milliseconds, futhi isikhathi sokuphendula sokukhanyisa ama-nanoseconds.Ngakho-ke, iye yasetshenziswa kabanzi emikhakheni yamarobhothi namalambu emoto.
5. ukulungiswa kokukhanya okuhle
Ngokomgomo womthombo wokukhanya wephoyinti le-LED, ukukhanya okukhanyayo noma ukuphuma kwe-flux kushintshwe kahle kusuka kokuyisisekelo samanje.Ukusebenza kwayo kungaba kukhulu noma kuncane phakathi kwebanga elilinganiselwe, futhi kunokulungiseka okuhle, okubeka isisekelo sokuqaphela ukukhanya okwaneliswa ngumsebenzisi nokulawula okungenasinyathelo kwemithombo yokukhanya yephoyinti le-LED.
