Ingabe Ama-Led Lights Amandla Amandla?

Ingabe Ama-Led Lights Amandla Amandla?

Amalambu e-LED (Light Emitting Diodes) asedume kakhulu eminyakeni yamuva nje ngenxa yokusebenza kahle kwamandla. Lezi zibani zisebenzisa amandla amancane kunokukhanyisa okuvamile, okuzenza zibe inketho engabizi futhi evumelana nemvelo kubathengi. Kulesi sihloko, sizohlola ukusebenza kahle kwamandla kwezibani ze-LED kanye nezinzuzo ezihlukahlukene abazinikezayo. Sizophinde sixoxe ngokuthi izibani ze-LED ziqhathaniswa kanjani nezinye izinhlobo zokukhanyisa, njengama-incandescent nama-fluorescent bulb. Ekupheleni kwalesi sihloko, uzoba nokuqonda okucacile kokusebenza kahle kwamandla kwezibani ze-LED nokuthi kungani kuyisinqumo esihlakaniphile kuzo zombili izidingo zokukhanyisa zokuhlala nezokuhweba.

Isayensi Ngemuva Kwezibani ze-LED

Izibani ze-LED ziwuhlobo lokukhanyisa okuqinile okuguqula ugesi ube ukukhanya ngokusebenzisa ama-semiconductors. Lapho amandla kagesi edlula ezintweni ze-semiconductor, ashukumisa ama-electron angaphakathi kwempahla, awenze akhulule ama-photon (ukukhanya). Le nqubo yaziwa ngokuthi i-electroluminescence, futhi iyona eyenza izibani ze-LED zisebenzise amandla. Ngokungafani nezibani zendabuko ze-incandescent, ezithembele ekushiseni umcu ukuze zikhiqize ukukhanya, izibani ze-LED zikhiqiza ukushisa okuncane kakhulu, okusho ukuthi amandla amaningi awasebenzisayo aguqulwa abe ukukhanya.

Izinto ze-semiconductor ezisetshenziswa ezibani ze-LED nazo zidlala indima ebalulekile ekusebenzeni kahle kwazo kwamandla. Izibani ze-LED zenziwa kusetshenziswa izinto ezifana ne-gallium, i-arsenic, ne-phosphorous, ezinezakhiwo ezithile ezivumela ukuthi zikhiphe ukukhanya kahle. Ngokuphambene, izibani ze-incandescent zithembele ekushiseni kwe-tungsten filament, edinga amandla engeziwe ukukhiqiza ukukhanya. Inhlanganisela yalezi zici yenza amalambu e-LED afinyelele ku-80% asebenzise amandla amaningi kunezinketho zokukhanyisa ezivamile.

Ukusebenza Kwamandla Kwezibani ze-LED

Esinye sezizathu eziyinhloko zokuthi kungani izibani ze-LED ziwonga amandla kangaka ukusetshenziswa kwazo okuphansi kwamandla. Amalambu e-LED adinga amandla amancane kakhulu ukuze akhiqize ukukhanya okufanayo namalambu endabuko. Isibonelo, isibani esivamile se-incandescent esingama-watt angu-60 singashintshwa ngesibani se-LED esingu-10-watt kuyilapho sinikeza izinga elifanayo lokukhanya. Lokhu kusho ukuthi izibani ze-LED zisebenzisa ingxenye encane kuphela yamandla adingekayo ukuze kunikwe amandla ukukhanyisa kwendabuko, okuholela ekwehleni kwezikweletu zikagesi kubathengi.

Esinye isici esinomthelela ekusebenzeni kahle kwamandla kwezibani ze-LED isikhathi eside sokuphila kwazo. Izibani ze-LED zingahlala izikhathi ezifika ku-25 ubude kunama-incandescent bulb futhi zifike izikhathi eziyishumi kunezibani ze-fluorescent. Lokhu kusho ukuthi izibani ze-LED zidinga ukushintshwa okumbalwa ngokuhamba kwesikhathi, okuholela kumandla engeziwe nokonga kwezindleko. Ukuqina kwezibani ze-LED nakho kuzenza kube ukukhetha okusimeme, njengoba zinciphisa inani lemfucuza ekhiqizwa ama-bulb alahliwe.

Ngaphezu kokusetshenziswa kwawo okuphansi kwamandla nokuphila isikhathi eside, izibani ze-LED nazo ziwonga amandla ngenxa yekhono lazo lokukhiqiza ukukhanya okuqondisayo. Ngokungafani nama-bulb endabuko, akhipha ukukhanya kuzo zonke izinhlangothi, izibani ze-LED zingaklanywa ukuthi zikhiphe ukukhanya endaweni ethile. Lesi sici sivumela ukukhanya okunembe kakhudlwana, ukunciphisa isidingo sezinto ezengeziwe noma izibonisi zokuqondisa kabusha ukukhanya lapho sidingeka khona. Ngenxa yalokho, izibani ze-LED zidla amandla amancane ukuze zifinyelele umphumela wokukhanyisa owufunayo, okuwenza abe yisinqumo esifanelekile sezinhlelo zokusebenza eziningi.

Izinzuzo Zendawo Yezibani ze-LED

Ukusebenza kahle kwamandla kwezibani ze-LED akuhumushi nje kuphela ukonga izindleko kubathengi kodwa futhi kunezinzuzo ezibalulekile zemvelo. Ngokusebenzisa amandla amancane, izibani ze-LED zinciphisa isidingo sikagesi, okubuye kwehlisa ukukhishwa kwegesi ebamba ukushisa okuvela ezitshalweni zamandla. Ngokusho koMnyango Wezamandla wase-US, ukusetshenziswa kabanzi kwezibani ze-LED kunamandla okunciphisa isidingo sikagesi sokukhanyisa cishe ngo-50%. Lokhu kwehliswa kokusetshenziswa kwamandla kungasiza ukunciphisa umthelela wokuguquka kwesimo sezulu futhi kuthuthukise izinga lomoya ezindaweni zasemadolobheni.

Izibani ze-LED azinazo izinto eziyingozi, njenge-mercury, ezingatholakala kuma-fluorescent bulb. Lokhu kwenza amalambu e-LED aphephe ukusetshenziswa futhi kube lula ukuwalahla ekupheleni kwesikhathi sawo sokuphila. Ukwengeza, isikhathi eside sokuphila kwezibani ze-LED kusho ukuthi ama-bulb ambalwa agcina esendaweni yokulahla imfucumfucu, okuqhubeka nokunciphisa umthelela wawo kwezemvelo. Sekukonke, ukusebenza kahle kwamandla kanye nezinzuzo zemvelo zamalambu e-LED kuwenza abe yinketho eqhubekayo kubo bobabili abathengi kanye neplanethi.

Ukuqhathanisa Izibani ze-LED nezinye Izinketho Zokukhanyisa

Uma uqhathanisa ukusebenza kahle kwamandla kwezibani ze-LED nezinye izinketho zokukhanyisa, kuyacaca ukuthi izibani ze-LED zidlula ama-bulb endabuko ezindaweni ezimbalwa ezibalulekile. Ama-incandescent bulbs ayinketho ewonga amandla kancane, njengoba ekhipha inani elibalulekile lokushisa futhi anesikhathi esifushane sokuphila. Ngakolunye uhlangothi, amalambu e-fluorescent awonga amandla amaningi kunama-incandescent, kodwa asasebenzisa amandla amaningi kunezibani ze-LED futhi aqukethe izinto eziyingozi.

Mayelana nokusebenza kahle kwamandla, izibani ze-LED yizona eziwinile, ezihlinzeka ngezinga eliphezulu lokonga amandla nezinzuzo zemvelo. Nakuba amalambu e-LED angase abe nezindleko zangaphambili eziphezulu kunama-bulb endabuko, ukusebenza kahle kwawo kwamandla esikhathi eside nokonga kwezindleko kuwenza utshalomali oluhlakaniphile kukho kokubili izicelo zokuhlala nezokuhweba. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, izindleko zamalambu e-LED kulindeleke ukuthi zehle kakhulu, ziwenze abe yinketho ethengekayo futhi ekhangayo kubathengi.

Ikusasa Lokukhanya Kwe-LED

Njengoba ubuchwepheshe be-LED buqhubeka nokuvela, ikusasa libukeka liqhakazile ekukhanyeni okuwonga amandla. Ukwakhiwa okusha kwe-LED nokukhiqiza kuholela ekongeni amandla okukhulu nakakhulu kanye nezinzuzo zemvelo. Isibonelo, ukuthuthuka kwezinto ze-phosphor nezindlela zokuhlanganisa imibala kuthuthukisa ikhwalithi yokukhanya okukhishwa izibani ze-LED, okwenza kuthandeke kakhulu ezinhlobonhlobo zezinhlelo zokusebenza.

Ukuhlanganiswa kwezibani ze-LED nezinhlelo zokukhanyisa ezihlakaniphile kanye nobuchwepheshe be-IoT (I-inthanethi Yezinto) nakho kudala amathuba amasha okusebenza kahle kwamandla nokusimama. Lezi zinhlelo zivumela ukulawula okunembayo nokuzishintsha kokukhanyisa, kuqhubeke nokunciphisa ukusetshenziswa kwamandla nokuthuthukisa ukusebenza kokukhanyisa. Ngenxa yalokhu, izibani ze-LED ziba yingxenye ebalulekile yokunyakaza okukhulayo okubheke ezixazululo zokukhanyisa ezonga amandla nemvelo.

Kafushane, izibani ze-LED ziwonga amandla ngokungangabazeki, zinikeza ukonga kwezindleko ezibalulekile, izinzuzo zemvelo, nokusebenza okuphakeme uma kuqhathaniswa nezinketho zokukhanyisa ezivamile. Njengoba abathengi beqhubeka nokubeka phambili ukusebenza kahle kwamandla kanye nokusimama, izibani ze-LED zibekwe esikhundleni sokuba yinketho ekhethwayo yezidingo zokuhlala, ezohwebo, kanye nezimboni. Ngokuthuthuka okuqhubekayo kubuchwepheshe be-LED kanye nesidingo esikhulayo sezixazululo ezonga amandla, ikusasa lokukhanyisa kwe-LED libukeka liqhakazile kunangaphambili.
