Kungani Ukukhanyisa Kwe-Led Kumba Kangaka?

Izinzuzo Zokukhanya kwe-LED

Ukukhanyisa kwe-LED (light-emitting diode) sekuye kwanda kakhulu eminyakeni yamuva nje, ngezinhlelo zokusebenza ezihlukahlukene ezindaweni zokuhlala, ezohwebo, nezimboni. Lokhu kudlondlobala kokuduma ngenxa yengxenye yezinzuzo eziningi ezinikezwa ukukhanyisa kwe-LED ngaphezu kokukhanyisa kwendabuko kwe-incandescent noma kwe-fluorescent. Akukhona nje ukuthi izibani ze-LED ziwonga kakhulu amandla, kodwa futhi zihlala isikhathi eside futhi zinikeza ukukhanya kwekhwalithi engcono. Kodwa-ke, i-drawback eyodwa evamile abantu abaningi ababhekana nayo lapho becabangela ukukhanya kwe-LED yizindleko eziphezulu. Ngakho-ke, kungani ukukhanya kwe-LED kubiza kangaka? Kulesi sihloko, sizohlola izizathu zethegi yamanani aphezulu ekukhanyeni kwe-LED nokuthi izinzuzo zidlula izindleko.

Ikhwalithi Nokuphila Okude

Esinye sezizathu eziyinhloko zokuthi kungani ukukhanya kwe-LED kubize kakhulu kunezinketho zokukhanyisa zendabuko izinga eliphezulu nokuphila isikhathi eside okuhlinzekwa yizibani ze-LED. Amalambu e-LED aziwa ngokuqina kwawo futhi angahlala isikhathi esingafika izikhathi ezingu-25 kunezibani zendabuko ze-incandescent futhi afinyelele izikhathi ezingu-10 ubude kunezibani ze-fluorescent. Lokhu kusho ukuthi nakuba amalambu e-LED angase eze nezindleko eziphezulu zangaphambili, ekugcineni uzogcina imali ngokuhamba kwesikhathi ngokungawashintshi njalo. Ukwengeza, ikhwalithi yokukhanya ekhiqizwa izibani ze-LED iphakeme kunaleyo yokukhanyisa kwendabuko, enikeza ukunikezwa nokusabalalisa kombala okungcono.

Ukusebenza Kwamandla

Esinye isici esinomthelela ezindlekweni eziphakeme zokukhanyisa kwe-LED wukusebenza kahle kwayo kwamandla. Izibani ze-LED zisebenzisa amandla amancane kakhulu kunezinketho zokukhanyisa ezivamile, okungaholela ekongeni kwezindleko ezinkulu ezikweletini zamandla ngokuhamba kwesikhathi. Ngokusho koMnyango Wezamandla wase-US, ukusetshenziswa kabanzi kwezibani ze-LED kunamandla okusindisa izigidigidi zamaRandi ezindleko zamandla. Nakuba izindleko zangaphambili zamalambu e-LED zingase zibe phezulu, ukusebenza kahle kwawo kwamandla kuwenza abe yinketho yokukhanyisa engabizi kakhulu futhi evumelana nemvelo ngokuhamba kwesikhathi.

Ukukhiqiza Nobuchwepheshe

Inqubo yokukhiqiza kanye nobuchwepheshe ngemuva kokukhanyisa kwe-LED nakho kudlala indima ebalulekile ezindleko zayo eziphakeme. Izibani ze-LED zidinga ubuchwepheshe obuthuthuke kakhulu nezinto zokwakha uma kuqhathaniswa nokukhanyisa kwendabuko, okunomthelela ephuzwini lazo lentengo eliphakeme. Ngaphezu kwalokho, inqubo yokukhiqiza izibani ze-LED iyinkimbinkimbi kakhulu futhi idla isikhathi, ihlanganisa ubuchwepheshe obunembile be-semiconductor kanye nemishini ekhethekile. Ngenxa yalokho, izindleko zokukhiqiza izibani ze-LED ziphakeme, ekugcineni ziholela entengo ephakeme yokuthengisa kubathengi.

Ucwaningo Nentuthuko

Ucwaningo oluqhubekayo nokuthuthukiswa kobuchwepheshe bokukhanyisa i-LED nakho kunomthelela ezindlekweni zayo eziphakeme. Izinkampani zitshala izinsiza ezibalulekile ekuthuthukiseni nasekuthuthukiseni imikhiqizo yokukhanyisa kwe-LED ukuthuthukisa ukusebenza kwayo, ukusebenza kahle, nokuqina. Lokhu kutshalwa kwezimali ocwaningweni nasekuthuthukisweni kubonakala ezindlekweni eziphakeme zokukhanyisa kwe-LED, njengoba abakhiqizi befuna ukubuyisela lezi zindleko ngokuthengiswa kwemikhiqizo. Kodwa-ke, intuthuko eyenziwe ngemizamo yocwaningo nentuthuko iyaqhubeka nokuthuthukisa ikhwalithi nokusebenza kahle kokukhanya kwe-LED, okwenza kube utshalomali olufanele kubathengi abaningi.

Isidingo Semakethe Nokuncintisana

Isidingo esikhulayo sokukhanyisa kwe-LED kanye nesimo sokuncintisana semakethe nakho kunomthelela emananini ayo. Njengoba abathengi abaningi namabhizinisi bebona izinzuzo zokukhanyisa kwe-LED, isidingo sale mikhiqizo siyaqhubeka sikhula. Lesi sidingo esikhulayo sidale imakethe encintisanayo yokukhanyisa kwe-LED, nabakhiqizi abahlukahlukene bebanga ingxenye yemboni. Nakuba lo mncintiswano ungaholela emananini aphansi kubathengi, ubuye uqhubekisele abakhiqizi ukuthi basungule futhi bahlukanise imikhiqizo yabo, okungaba nomthelela ezindlekweni eziphakeme ezihambisana nokukhanyisa kwe-LED.

Kafushane, ukukhanyisa kwe-LED kunikeza izinzuzo eziningi, okuhlanganisa ukusebenza kahle kwamandla, ukuphila isikhathi eside, kanye nekhwalithi ephezulu, okubonisa izindleko zakho eziphezulu uma kuqhathaniswa nezinketho zokukhanyisa zendabuko. Nakuba ukutshalwa kwezimali kwangaphambili ekukhanyeni kwe-LED kungase kube kukhulu, ukonga kwesikhathi eside kanye nezinzuzo zemvelo kukwenza kube ukukhetha okufanelekile kubathengi abaningi. Ukwengeza, intuthuko eqhubekayo kubuchwepheshe be-LED kanye nesimo semakethe esincintisanayo kungenzeka kuqhubekisele phambili intuthuko kanye nezindleko ezingase zehle ngokuzayo. Ekugcineni, isinqumo sokutshala imali ekukhanyeni kwe-LED sincike ekukaleni izindleko zangaphambili ngokuqhathanisa nezinzuzo zesikhathi eside nokonga okuhlinzekwa yizibani ze-LED.
