Smd-Kokes: taariikhda iyo ugu weyn ee dabeecadaha

LED nin saamaynta lagu arkay markii ugu horeysay 90 sano ka hor. Tani waxay ka dhacay Russia ee 1923, markii Oleg Losev in Nizhny Novgorod markii ugu horaysay lagu arkay by luminescence ee carbide Silicon shaybaarka electronic. articles Sayniska on this maadada la daabacay ee 30meeyada ee qarnigii la soo dhaafay, iyo design ugu horeysay u muuqday oo kaliya in 70s ee. in Leningrad, Zelenograd iyo Kaluga. horumarinta firfircoon ee farsamooyinka la xiriira amarrada bilayska taraafikada for soo saaridda ee nalalka waddooyinka ee 1000 in 850 guuradii ee magaalada, taas oo halkii incandescent laambadihii isticmaalo a Kokes cagaaran dhalaalaya.

LED waa chip Semiconductor lifaaqan substrate ah aluminium ama copper iyo nidaamka indhaha loogu talagalay iyo boosteejada ah. LED smd (dusha faahfaahin Montage) ka noocyada kale waa in lagu gartaa in qaybo ka mid ah dhexdeeda waxaa si toos ah Jaha dushiisa. dhismayaasha Crystal for technology this waxaa la koray by epitaxy organometallic. Inta lagu jiro habkan, hal maalin gudaheed, aad u koraan kara qaabka la doonayo (chips) ugu badnaan 12 muhashada.

Ka dibna, ku kiristaalo helay waxaa lagu daaweeyaa siyaabo of technology sare, oo waxay u soo ururay oo soo saarka jirka lagu sameeyo waxaa laga dalbadaa, walxaha dheeraad ah oo doonaysay diyaarin kulaylka diiradda. tallaabo Tani waa kharash aad u, si uu Kokes ku smd waa ka qaalisan yihiin nalalka caadiga ah. Waxaa la rumeysan yahay in qiimaha halkii Lumen ee ay LED 100 jeer ka badan unit ka mid ah soo saaray oo la laambad halogeen ah.

Sifooyinka wanaagsan ee nidaamka ka mid ah kulaylka hooseeyo, adigoo daahir ah midabka sare, maqnaanshaha shucaac infrared iyo ultraviolet ku filan xoog, cimri dherer iyo ammaanka. Maanta liruyuschey dalka oo dhan, halkaas oo midhaha smd-Kokes, waa Japan.

Marka la walxahaasi shaqeeya waxaa badanaa loo arkaa sifooyinka soo socda:

- iftiin, kaas oo noqon kara cad (kulul ama qabow), iyo buluug, cagaar ah, huruud ama casaan. iftiinka White smd-Kokes laga helo siyaabo badan, oo ay ku jiraan habka RGB ah, marka midabyo kala duwan lagu qaso by gelis ama nidaam kale indhaha;

- dalkiisa hooyo ee chip (sida caadiga ah, Taiwan);

- daadanayo iska Ifto Yuuna (lumens);

- baahan yahay danab;

- tirada kiristaalo (chips);

- xoog hadda loo baahan yahay;

- xagal of Nuur (45 ilaa 140 digrii);

- joogitaanka ama maqnaanshaha of substrate ah, taas oo inta badan waa kharash dheeraad ah.

Smd-Kokes si ballaaran loo isticmaalo nalalka meelaha badan oo kala duwan. samaynta ay jecel yihiin tayada sare iftiinka iyo ammaanka korontada, shaqaalaha danabka dadweynaha - isticmaalka tamarta yar iyo iska caabin jejebiyaan sare. marka laga reebo kaliya ee codsiga of teknoolajiyada kuwaas oo maanta ay joogaan goobaha waaweyn, si ay u ma waxaa loo isticmaalaa wax soo saarka. strip LED waxaa lagu arki karaa maanta ee guryaha, meheradaha iyo xafiisyada, oo ay ku jiraan kuwa meelaha jawi qoyan, maxaa yeelay, waxaa jira noocyo ka mid ah dioska- kamana cabsadaan oo biyo ah.

Nolosha adeeg ah qalabka waa wax weyn (ilaa 50 000 oo saacadood daydo-dhamaadka sare), sidaas darteed waxaan odhan karaa, smd-Kokes - waa aalad ugu fiican ee nalalka mustaqbalka.
