SMD-LED: Umlando kanye main izici

LED imiphumela indoda babebhekwa okokuqala eminyakeni engu-90 edlule. Lokhu kwenzeka ngo-Russia ngo-1923, lapho u-Oleg Losev e Nizhny Novgorod yaqale waphawula yi luminescence ka-silicon Carbide laboratory electronic. izihloko Scientific ngale ndaba zashicilelwa 30s kwekhulu elidlule, futhi idizayini uqala ukuvela kuphela 70s. eLeningrad, Zelenograd nasezindaweni Kaluga. ukuthuthukiswa Active amasu elihlobene ne-oda amaphoyisa omgwaqo womshini amarobhothi e 1000 kuya 850 weminyaka le-dolobha, lapho esikhundleni izibani incandescent wasebenzisa LED elikhanyayo oluhlaza.

I-LED kuyinto chip Semiconductor enamathiselwe substrate aluminiyamu noma ithusi futhi yakhelwe uhlelo optical kanye ezikhumulweni. LED SMD (ngaphandle imininingwane montage) kusukela nezinye izinhlobo ungachazwa ukuthi izingxenye ekulo ukukhwezwa ngqo phezulu. Crystal izakhiwo ngoba lobu buchwepheshe etshalwa ngu epitaxy organometallic. Kule nqubo, ngaphakathi usuku olulodwa, ungakwazi ukhule isakhiwo oyifunayo (chips) for lungene 12 substrates.

Ngemva kwalokho, le amakristalu etholwe ziphathwa ngenxa yobuchwepheshe okusezingeni eliphezulu: bona ababuthelwa umzimba wenza okukhiphayo zisetshenziswa, izinto ezengeziwe futhi babefisa ahlelwe ukushisa ngokugxila. Lesi sinyathelo kakhulu izindleko, ngakho SMD LED ayabiza kunamawashi ama ezivamile. Kukholakala ukuthi izindleko inesikhala ngayinye eyenziwe LED izikhathi 100 ephakeme kunaleyo iyunithi babebhala ephethe ilambu Halogen.

Izimfanelo ezinhle zalezi zinhlelo zihlanganisa ukushisa ongaphakeme, high umbala ubumsulwa, ukungabi khona kwe-infrared kanye emisebeni yelanga esanele namandla, ukuqina kanye nokuphepha. Namuhla liruyuschey ezweni lonke, lapho umkhiqizo SMD-LED, Japan.

Lapho ukusebenza lezi zinto ngokuvamile kubhekwa izici ezilandelayo:

- ukukhanya, okungaba mhlophe (efudumele noma ezibandayo), blue, oluhlaza, ophuzi noma obomvu. ukukhanya White SMD-LED etholakala ngezindlela eziningi, kuhlanganise RGB indlela, lapho imibala ehlukene axutshwa ngumuntu lens noma kwenye ohlelweni optical;

- ezweni lendabuko chip (ngokuvamisile, Taiwan);

- ecucuza elikhanyayo (lumens);

- edingekayo voltage;

- inani zinhlayiya (chips);

- amandla adingekayo zamanje;

- engela sokukhanyisa (45 ukuze 140 degrees);

- khona noma ukungabi khona substrate, okuyinto evame izindleko ezengeziwe.

SMD-LED kabanzi ukukhanya ezindaweni eziningi ezahlukene. Abaklami zabo uthando ayenalo izinga okusezingeni yokukhanya nokuphepha kagesi, abasebenzi ezibalulekile emphakathini - I-ongaphakeme energy ukusetshenziswa kanye high ukumelana ocekela phansi. Okuwukuphela komehluko ukusetshenziswa kwalezi ubuchwepheshe namuhla khona izindawo ezinkulu, ngakho kungukuthi asetshenziswa ekukhiqizeni. strip LED kungabonwa nanamuhla emakhaya, amathilomu kanye namahhovisi, kuhlanganise nalezo ezindaweni endaweni zinomswakama ngoba kunezinhlobo ezithile diodes asesabi amanzi.

Impilo nenkonzo yalaba amadivayisi mikhulu (kufika emahoreni angu-50 000 ukuze ephezulu onobuhle), ukuze sikwazi ukusho, SMD-LED - yilona thuluzi engcono ukukhanya esikhathini esizayo.
