Ma LED Mwenje Anomirirei?

Mwenje ye LED, inomirira Chiedza Emitting Diodes, yave kuwedzera mukurumbira mumakore achangopfuura nekuda kwesimba radzo, hupenyu hurefu, uye kuita zvakasiyana. Kunyangwe iwe uchijairana nemwenje we LED kana kuti uchangotanga kudzidza nezvawo, zvakakosha kuti unzwisise kuti marambi e LED anomirirei uye kuti angakubatsira sei. Muchikamu chino, tichaongorora zvakasiyana-siyana zvemwenje we LED, kusanganisira nhoroondo yavo, teknolojia, kushandiswa, uye zvakanakira. Pakupera kwechinyorwa chino, iwe unenge uine nzwisiso yakazara yemwenje ye LED uye kukosha kwayo munyika yanhasi.

Zviratidzo Nhoroondo ye LED Mwenje

Nhoroondo yemwenje ye LED inodzokera kumashure kwekutanga kwezana ramakore rechi20 apo masayendisiti akawana chiitiko che electroluminescence mune zvimwe semiconductor zvinhu. Zvisinei, hazvina kusvika kuma1960 apo mwenje we LED wakagadzirwa. Yekutanga inoshanda LED yakagadzirwa naNick Holonyak Jr. muna 1962 paaishandira General Electric. Iyi yekutanga LED yakaburitsa yakaderera-yakanyanya dzvuku mwenje, asi yakateya nheyo yekuvandudzwa kwemamwe ma LED mwenje mumakore anotevera.

Mumakumi mashoma emakore akatevera, vaongorori uye mainjiniya vakaita kufambira mberi kwakakura muhunyanzvi hwe LED, zvichitungamira mukugadzirwa kwemwenje ye LED mune akasiyana mavara uye intensity. Mumakore ekuma1990, ma LED ebhuruu akagadzirwa zvakabudirira, izvo zvakagonesa kugadzirwa kwemwenje machena e LED. Nhasi, magetsi e LED anowanikwa mune zvakasiyana-siyana zvemavara uye anoshandiswa mumashandisirwo asingaverengeki, kubva pakuvhenekera kwekugara kusvika kumagetsi emagetsi.

Zviratidzo Technology Kuseri kwe LED Mwenje

Iyo tekinoroji iri kumashure kwemwenje ye LED yakavakirwa pamusimboti we electroluminescence, iyo nzira yekuburitsa mwenje semhedzisiro yemagetsi inopfuura nepakati semiconductor zvinhu. Mwenje ye LED ine semiconductor diode inoburitsa chiedza kana magetsi achipfuura napo. Iyo inonyanya kuzivikanwa semiconductor zvinhu zvinoshandiswa mumwenje we LED igallium arsenide, gallium phosphide, uye gallium nitride.

Mwenje dze LED dzinozivikanwa nekushanda kwesimba radzo, sezvo dzichishandura chikamu chepamusoro chesimba remagetsi kuita chiedza kana zvichienzaniswa nemwenje wekare incandescent kana fluorescent. Izvi zvinowanikwa kuburikidza nekushandiswa kwe "bandgap" mune semiconductor zvinhu, izvo zvinobvumira kushanduka kwakanaka kwesimba muchiedza. Pamusoro pezvo, marambi e LED ane hupenyu hurefu kupfuura mwenje wechinyakare, aine mamwe ma LED anosvika maawa makumi mashanu kana kupfuura.

Zviratidzo Kushandiswa kweMagetsi e LED

Mwenje ye LED inoshandiswa mune zvakasiyana-siyana zvekushandisa, kubva pakuvhenekera kweimba kusvika kune zvekutengeserana uye zvemabhizimisi. Munzvimbo dzekugara, mwenje we LED anowanzo shandiswa kuvhenekera zvakajairika, kuvheneka basa, uye mwenje wekushongedza. Kushanda kwesimba ravo uye hupenyu hurefu hunovaita sarudzo yakanaka yekudzikisa mashandisirwo emagetsi uye mari yekugadzirisa. Magetsi e LED anoshandiswawo mukuratidzira kwemagetsi, sewachi yedhijitari, marambi emigwagwa, uye zviratidzo zvekunze, nekuda kwekupenya kwavo uye kuoneka.

Munzvimbo dzekutengeserana uye dzemaindasitiri, mwenje we LED unoshandiswa kune zvakasiyana siyana, zvinosanganisira mwenje wemba yekuchengetera, mwenje yemumugwagwa, uye mwenje wekuvaka. Mwenje dze LED dzinoshandiswawo zvakanyanya mumotokari uye zvifambiso zvekufambisa, senge marambi emusoro, mabhureki mwenje, uye mukati memwenje. Iko kushandiswa kwakasiyana-siyana uye kusimba kwemwenje ye LED inoita kuti ive yakakodzera kune dzakasiyana siyana dzemukati uye kunze kwekushandisa.

Zviratidzo Zvakanakira Mwenje dze LED

Pane zvakati wandei zvakanakira kushandisa mwenje we LED zvichienzaniswa neyechinyakare mwenje matekinoroji. Imwe yemabhenefiti makuru ndeyekushanda kwesimba ravo, sezvo marambi e LED achidya simba shoma uye achigadzira mwenje wakawanda, zvichikonzera kuderera kwemagetsi mabhiri uye kuderedzwa kwemamiriro ekunze. Mwenje ye LED inewo hupenyu hurefu, izvo zvinoreva kushoma kudzoreredza uye kuderera kwekugadzirisa mutengo.

Imwe mukana wezviedza zve LED ndeyekusiyana-siyana kwavo maererano neruvara uye kusimba. Mwenje ye LED inogona kuburitsa mavara akasiyana-siyana, ichiita kuti ive yakakodzera kune dzakasiyana siyana mwenje mhedzisiro uye maapplication. Pamusoro pezvo, marambi e LED anobatika ipapo uye haadi nguva yekudziya, kusiyana nemamwe marambi echinyakare. Izvi zvinoita kuti zvive zvakanakira maapplication apo mwenje unobuda pakarepo unodiwa, senge mukuvhenekesa kwechimbichimbi uye mwenje unofambisa.

Symbols Ramangwana re LED Mwenje

Ramangwana remwenje we LED rinotaridzika kuva rinovimbisa, nekutsvagisa nekuenderera mberi kwakanangana nekuwedzera kuvandudza kushanda kwavo, hupenyu, uye kuita zvakasiyana. Vatsvagiri vari kushanda mukugadzira zvakatonyanya kushanda semiconductor zvinhu uye nzira dzekugadzira kuderedza mutengo wemwenje we LED uye kuita kuti iwanikwe kune vatengi.

Kune zvakare kufarira kuri kukura kwekushandisa akangwara masisitimu emwenje anoshandisa tekinoroji yeLED kupa zvigadziriso zvemwenje zvinogoneka uye zvine simba. Aya masisitimu ekuvhenekesa akangwara anogona kudzorwa kure uchishandisa ma smartphones kana mamwe maturusi, achibvumira vashandisi kugadzirisa kupenya, ruvara, uye kuronga zvinoenderana nezvavanofarira. Pamusoro pezvo, kubatanidzwa kwemarambi eLED ane ma sensors uye otomatiki tekinoroji inotarisirwa kuwedzera kuchengetedza kwesimba uye nyore kweiyo LED mwenje masisitimu.

Mukupedzisa, zviedza zve LED zvakabva kure kubva pazvakatangwa muma1960, uye zvakave chikamu chakakosha chemazuva ano ekuvhenekera uye kuratidza teknolojia. Nhoroondo, tekinoroji, mashandisirwo, uye zvakanakira mwenje we LED zvese zvinobatsira mukukosha kwazvo munyika yanhasi. Sezvo kuenderera mberi kutsvagisa nekusimudzira kuri kuramba kuchivandudza tekinoroji yeLED, tinogona kutarisira kuona mamwe maapplication uye mabhenefiti emwenje e LED mune ramangwana. Zvingave munzvimbo dzekugara, dzekutengeserana, kana dzemaindasitiri, marambi e LED anomirira kushanda kwesimba, kurarama kwenguva refu, uye kuita zvakasiyana-siyana, zvichiita kuti ive sarudzo inogadzika uye inoshanda yemhinduro dzemwenje.
