Izibani ZeLED Zimeleni?

Izibani ze-LED, ezimele i-Light Emitting Diodes, sezidume kakhulu eminyakeni yamuva nje ngenxa yokusebenzisa kahle kwawo amandla, ubude besikhathi sokuphila, kanye nokuguquguquka. Kungakhathaliseki ukuthi ujwayelene nezibani ze-LED noma usaqala ukufunda ngazo, kubalulekile ukuqonda ukuthi izibani ze-LED zimeleni nokuthi zingakuzuzisa kanjani. Kulesi sihloko, sizohlola izici ezihlukahlukene zezibani ze-LED, okuhlanganisa umlando wazo, ubuchwepheshe, ukusetshenziswa, kanye nezinzuzo. Ekupheleni kwalesi sihloko, uzoba nokuqonda okuphelele kwezibani ze-LED kanye nokubaluleka kwazo emhlabeni wanamuhla.

Izimpawu Umlando Wezibani ze-LED

Umlando wezibani ze-LED uhlehlela ekuqaleni kwekhulu lama-20 lapho ososayensi bethola ukwenzeka kwe-electroluminescence ezintweni ezithile ze-semiconductor. Kodwa-ke, kwaze kwaba ngawo-1960 lapho izibani ze-LED ezisebenzayo zasungulwa. I-LED yokuqala esebenzayo yasungulwa ngu-Nick Holonyak Jr. ngo-1962 ngenkathi esebenzela i-General Electric. Le LED yasekuqaleni yayikhipha ukukhanya okubomvu okunomfutho ophansi, kodwa yabeka isisekelo sokuthuthukiswa kwezibani ze-LED ezithuthuke kakhulu eminyakeni ezayo.

Emashumini ambalwa eminyaka alandelayo, abacwaningi nonjiniyela benza intuthuko enkulu kubuchwepheshe be-LED, okuholele ekuthuthukisweni kwezibani ze-LED ngemibala nokuqina okuhlukahlukene. Ngawo-1990s, ama-LED aluhlaza adalwe ngempumelelo, avumela ukukhiqizwa kwezibani ze-LED ezimhlophe. Namuhla, izibani ze-LED zitholakala ngemibala ehlukahlukene futhi zisetshenziselwa izinhlelo zokusebenza ezingenakubalwa, kusukela ekukhanyisweni kokuhlala kuya ekubonisweni kwe-elekthronikhi.

Izimpawu Ubuchwepheshe Behiya Izibani LED

Ubuchwepheshe obungemuva kwezibani ze-LED busekelwe kumgomo we-electroluminescence, okuyinqubo yokukhipha ukukhanya njengomphumela wamanje kagesi odlula ezintweni ze-semiconductor. Amalambu e-LED aqukethe i-semiconductor diode ekhipha ukukhanya lapho umsinga kagesi udlula kuwo. Izinto ezisetshenziswa kakhulu ze-semiconductor ezisetshenziswa izibani ze-LED yi-gallium arsenide, i-gallium phosphide, ne-gallium nitride.

Izibani ze-LED zaziwa ngokusebenza kahle kwamandla kagesi, njengoba ziguqula iphesenti eliphezulu lamandla kagesi libe ukukhanya uma kuqhathaniswa nezibani zendabuko ze-incandescent noma ze-fluorescent. Lokhu kufinyelelwa ngokusebenzisa "i-bandgap" kumpahla ye-semiconductor, evumela ukuguqulwa okusebenzayo kwamandla abe ukukhanya. Ukwengeza, izibani ze-LED zinesikhathi eside sokuphila kunezibani zendabuko, namanye ama-LED ahlala amahora angafika kwangu-50,000 noma ngaphezulu.

Izimpawu Ukusetshenziswa Izibani LED

Izibani ze-LED zisetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, kusukela ekukhanyisweni kwasendlini kuya kwezinjongo zezohwebo nezimboni. Ezilungiselelweni zokuhlala, izibani ze-LED zivame ukusetshenziselwa ukukhanyisa okuvamile, ukukhanyisa umsebenzi, nokukhanyisa kokuhlobisa. Ukusebenza kahle kwawo kwamandla kanye nempilo ende kuwenza abe yinketho ekahle yokunciphisa ukusetshenziswa kwamandla kanye nezindleko zokuwanakekela. Izibani ze-LED ziphinde zisetshenziswe ekubonisweni kwe-elekthronikhi, njengamawashi edijithali, amarobhothi, nezimpawu zangaphandle, ngenxa yokukhanya nokubonakala kwazo.

Ezilungiselelweni zezentengiselwano nezimboni, izibani ze-LED zisetshenziselwa izinjongo ezihlukahlukene, okuhlanganisa ukukhanya kwendawo yokugcina impahla, ukukhanya komgwaqo, nokukhanyisa kwezakhiwo. Amalambu e-LED nawo asetshenziswa kakhulu ezinhlelweni zezimoto nezokuthutha, njengezibani zangaphambili, amalambu amabhuleki, nokukhanyisa kwangaphakathi. Ukuguquguquka nokuqina kwezibani ze-LED kuzenza zifanelekele uhla olubanzi lwezinhlelo zokusebenza zangaphakathi nangaphandle.

Izimpawu Izinzuzo LED Lights

Kunezinzuzo ezimbalwa zokusebenzisa izibani ze-LED uma kuqhathaniswa nobuchwepheshe bokukhanyisa bendabuko. Enye yezinzuzo eziyinhloko amandla abo okusebenza kahle, njengoba izibani ze-LED zisebenzisa amandla amancane futhi zikhiqiza ukukhanya okwengeziwe, okuholela emalini ephansi yamandla kanye nokunciphisa umthelela wendawo. Amalambu e-LED aphinde abe nesikhathi eside sokuphila, okusho ukuthi ukushintshwa okungajwayelekile kanye nezindleko zokunakekela eziphansi.

Enye inzuzo yezibani ze-LED ukuguquguquka kwazo ngokwemibala nokuqina. Izibani ze-LED zingakhiqiza izinhlobonhlobo zemibala, zizenze zifanele imiphumela yokukhanyisa ehlukahlukene kanye nezinhlelo zokusebenza. Ukwengeza, izibani ze-LED zikhanya ngokushesha futhi azidingi isikhathi sokufudumala, ngokungafani nezinye izibani zendabuko. Lokhu kuzenza zibe zilungele izinhlelo zokusebenza lapho ukukhanya okuphumayo kuyadingeka khona, njengokukhanyiswa kwesimo esiphuthumayo nezibani ezisebenza ukunyakaza.

Izimpawu Ikusasa Izibani LED

Ikusasa lezibani ze-LED libukeka lithembisa, ngocwaningo oluqhubekayo nentuthuko egxile ekuthuthukiseni ukusebenza kahle kwazo, isikhathi sokuphila, kanye nokuguquguquka. Abacwaningi basebenzela ukuthuthukisa izinto ezisebenza kahle kakhulu ze-semiconductor kanye nezinqubo zokukhiqiza ukuze banciphise izindleko zezibani ze-LED futhi bazenze zifinyeleleke kakhudlwana kubathengi.

Kukhona nesithakazelo esikhulayo sokuqalisa izinhlelo zokukhanyisa ezihlakaniphile ezisebenzisa ubuchwepheshe be-LED ukuze zinikeze izixazululo zokukhanyisa ezenziwe ngokwezifiso neziwonga amandla. Lezi zinhlelo zokukhanyisa ezihlakaniphile zingalawulwa ukude kusetshenziswa ama-smartphone noma amanye amadivaysi, okuvumela abasebenzisi ukuthi balungise ukukhanya, umbala, nokuhlela ngokuya ngokuthanda kwabo. Ukwengeza, ukuhlanganiswa kwezibani ze-LED nezinzwa kanye nobuchwepheshe bokuzenzakalela kulindeleke ukuthi kuthuthukise ukonga amandla kanye nokwenza lula kwezinhlelo zokukhanyisa ze-LED.

Sengiphetha, izibani ze-LED sezihambe ibanga elide kusukela ekuqaleni kwawo-1960, futhi seziyingxenye ebalulekile yobuchwepheshe besimanje bokukhanyisa nokubonisa. Umlando, ubuchwepheshe, ukusetshenziswa, kanye nezinzuzo zezibani ze-LED konke kunomthelela ekubalulekeni kwazo emhlabeni wanamuhla. Njengoba ucwaningo oluqhubekayo nokuthuthukiswa kuqhubeka kuthuthukisa ubuchwepheshe be-LED, singalindela ukubona izinhlelo zokusebenza ezintsha nezinzuzo eziningi zezibani ze-LED esikhathini esizayo. Kungakhathaliseki ukuthi kusezindaweni zokuhlala, ezentengiselwano, noma izilungiselelo zezimboni, izibani ze-LED zimelela ukonga kwamandla, ukuphila isikhathi eside, nokuguquguquka, okuwenza abe ukukhetha okuzinzile nokusebenzayo kwezixazululo zokukhanyisa.
