Thyristor LED. Iimpawu nangemigaqo yokusebenza

Thyristor LED - oku kuyindlela olukhulu kwiinkcukacha ezikhoyo namhlanje, ezisetyenziswa xa kusenziwa izixhobo zokukhanya. Izinto eziluncedo LED: ixesha elide kulo msebenzi, ukusetyenziswa kwamandla eliphantsi kunye nomlinganiselo ezincinane.

Ummiselo kusebenza kuwo i-LED

Isizathu inkqubo chweba na recombination le mingxuma ngokuqinisekileyo ityala kunye amasuntswana kakubi abekwe kwindawo ph-nguqu. Le ndawo elilujongano izinto ezimbini (semiconductors) kunye umthamo ezahlukeneyo yangoku conductivity. Ukudala ukukhanya okuqaqambileyo isakhiwo multilayer chip LED. Ubumhlophe yayo kwandiswe ngokusebenzisa ukungaqondani nkqi, kodwa ixabiso elikhulu diode yangoku lungangaphumeleli. ukukhanya LED zilungiswe ngendlela ukuhla. ukwakhiwa yayo ilula kakhulu, kodwa ngaxeshanye, abenzi abaninzi musa kukuxelela imfihlelo imveliso iimveliso zayo.

Ukuza kuthi ga ngoku, LED tiristotny mihla elinemveliso kakhulu, ngenxa yokuba parameter yayo ukusebenza ukususela-60 ukuya kuma-70%. Xa sithelekisa isibane yale igqengezelayo (nokusebenza apho 5-7 kuphela%) ne-LED, i yamva umlinganiselo ngcono kweshumi amaxesha. Ixesha lokusebenza ichazwe ngentla izixhobo zokukhanyisa ezisebenzisa ukukhanya-esikhupha diode thyristor, uneminyaka elishumi lokukhanya okuqhubekayo. yokonga amandla xa usebenzisa LED, xa kuthelekiswa ne-LDR imalunga ne-50%, xa kuthelekiswa ne yale igqengezelayo - 85%.

Imveliso Ukukhanya ilight mihla ukuba akhuphisane IPF kunye HPS (kunye DNaZ). Eli nani ilingana 150 lm / W. Ithuba payback kwezibane LED - iminyaka 2-3. Emva koko, lo eseleyo iminyaka elishumi, undisindisa 85% umbane osetyenzisiweyo nyanga nganye.

LED. iimpawu

LED, ziziphi iimpawu ezigqiba ongekho ngaphantsi analogue, ube nalemiba ilandelayo eziluncedo:

• ekwenziweni LED asetyenziswa iglasi, ngoko sifaka Isibane olu hlobo eliphezulu uqinile, ukungcangcazela ukumelana nokuthembeka;
• LED ukumelana ukuhla ombane anigqibele 0.4-0.6 A kuphela;
• Thyristor LED isebenza ngokufanelekileyo kwiimeko ezinzima, nokuba kumaqondo obushushu asezantsi kakhulu.

Ukuqalisa LED, kufuna luyabiza diode ibhulorho, ebangela ixabiso kwezibane ngaphambili kakhulu overpriced. Abavelisi kusonjululwa le ngxaki. Idayagram utshintshelwe kwaye endaweni thyristor dimmers triac ziye isicelo. Umphumo waba isixhobo ezibandakanya thyristors ezimbini idityaniswe ngokunxuseneyo, ekhawuntarini ithetha. Ngenxa kule ezintsha, imfuneko ibhulorho diode angekhoyo namhlanje. Esi sigqibo sabangela ukuba iimveliso Akubizi kakhulu kwaye kakhulu kwandise umgangatho nokhuseleko kunye nomgangatho iimpahla ngokwesiseko le thyristors.

Thyristor LED lisetyenziswa ekwenziweni izixhobo zokukhanya. ubomi inkonzo zayo ezinde, ukuthembeka kunye nokusebenziseka akholiswe abathengi, njengoko neendawo kunye nezinye izixhobo nge-LED-ukhanyiso ngokoqoqosho nje kuphela, kodwa jonga elihle kakhulu.
