SMD-LEDs: nhoroondo uye huru unhu

Akatungamirira Migumisiro murume kuonekwa kekutanga makore 90 akapfuura. Izvi zvakaitika muna Russia muna 1923, apo Oleg Losev muna Nizhny Novgorod yakatanga kucherechedzwa nokuda luminescence kuti nesilicon carbide yemagetsi murabhoritari. nyaya Scientific nezvenyaya iyi dzakabudiswa muna 30s remakore rapfuura, uye wokutanga magadzirirwo akazviratidza chete 70s. muna Leningrad, Zelenograd uye Kaluga. Active Kugadzirwa unyanzvi chokuita motokari mapurisa maodha kugadzirwa rwemotokari mwenje muna 1000 kusvika 850 gore guru, iyo pane incandescent mwenje vaishandisa rakajeka mitema LEDs.

The zvakatungamirira iri semiconductor Chip akabatana kuti substrate pamusoro aruminiyamu kana mhangura uye yakagadzirwa Manyiminya maitiro uye zviteshi. Akatungamirira SMD (pamusoro montage mashoko) kubva dzimwe mhando kunoratidzwa muna kuti zvikamu imomo vari hwavapo zvakananga pamusoro pemvura. Crystal hurongwa nokuti zvemichina ichi vava ne organometallic epitaxy. Panguva iyi, mukati zuva rimwe, unogona kukura zvinodiwa mamiriro (Chips) kuti vaifanira 12 substrates.

Zvadaro, mukuru vakawana crystals vabatwe pachishandiswa yakakwirira michina: vakaunganira muviri wakaita outputs anechekuita, mamwe zvinhu uye mukakumbira akaronga kupisa kutaura. Danho iri chaizvo cost, saka SMD LEDs anodhura pane kwakajairika Mabumba. Zvinonzi vaidavira kuti mutengo chete lumen kunotangira akatungamirira nguva 100 kupfuura chete chikwata yakabereka aine halogen rambi.

Zvakanaka zvatariswa aya nehurongwa zvinosanganisira yakaderera kupisa, mukuru ruvara kuchena, kusavapo michini uye ultraviolet nemwaranzi yakakwana simba, mukurumari uye kuchengeteka. Nhasi liruyuschey nyika yose, apo zvibereko SMD-LEDs, ndiye Japan.

Kana tichishanda zvinhu izvi zvinowanzonzi zvinotevera unhu:

- chiedza, izvo zvinogona chena (inodziya kana inotonhora), zvitema, mutema, yellow kana tsvuku. White chiedza SMD-LEDs vari vakawana nenzira dzakawanda, kusanganisira RGB nzira, kana mavara akasiyana yakasananiswa kunoitwa izvo kana mumwe Manyiminya hurongwa;

- nyika yaigara Chip (yemanyorero, Taiwan);

- luminous nekubudisa (lumens);

- zvaida voltage;

- nhamba crystals (Chips);

- anodiwa simba ano;

- angled okuvhenekesa (45 kusvika 140 madhigirii);

- kuvapo kana kusavapo substrate, izvo kazhinji chimwezve mutengo.

SMD-LEDs anoshandiswa nevakawanda okuvimba munzvimbo dzakawanda dzakasiyana. vagadziri vavo rudo nokuti mukuru unhu chiedza uye magetsi kuchengeteka, vashandi vane paruzhinji utilities - nokuti pasi simba zvinodyiwa uye yakakwirira vandal nemishonga. The chete Kusara kuti kushanda ruzivo izvi nhasi ndiyo kuvapo munzvimbo huru, saka hazvina kushandiswa mukurima. Akatungamirira Pfekenura anogona kuonekwa nhasi mudzimba, cafes uye mahofisi, kusanganisira vaya vari munzvimbo vane nyorovera ezvinhu, nokuti pane mamwe diodes havatyi mvura.

The upenyu basa mano izvi ndizvo chaizvo guru (kusvika 50 000 maawa kuti mukuru-magumo yokutevedzera), saka tinogona kutaura, SMD-LEDs - ndiyo yakanakisisa chokushandisa okuvimba mune ramangwana.
