Thyristor LED. Izici kanye Umgomo we operation

Thyristor LED - lokhu kuyindlela olukhulu imininingwane ekhona namuhla, ezisetshenziswa ekwakheni ama-amadivayisi ukukhanyisa. Izinzuzo LED: nempilo ende operation, ukhwaliti amandla ukusetshenziswa Ubukhulu ezincane.

Umgomo we operation ye LED

Isizathu inqubo luminescence iyona recombination emigodini kahle icala nezinhlayiyana omubi icala ezonini PH-inguquko. Le ndawo yiyona esibonakalayo izinto ezimbili (Semiconductors) nge ezahlukene zamanje conductivity umthamo. Ukudala kukhanya eliqhakazile isakhiwo multilayer chip LED. ukukhanya kwalo zingandiswa ngokusebenzisa ukungezwani eqinile, kodwa nge value elikhulu wamanje diode ongahlabeki. ukukhanya LED kungase kushintshwe bebheke ngincipha. ukwakhiwa kwalo silula, kodwa ngesikhathi esifanayo, abakhiqizi abaningi abathandanga ukudalula Imfihlo ukukhiqizwa imikhiqizo yayo.

Kuze kube manje, yesimanje LED tiristotny esikhiqizayo, ngoba ukusebenza kahle yayo amabanga kusuka 60 kuya 70%. Uma siqhathanisa isibani esikhipha (nekusebenta okuyinto% 5-7 kuphela) ne LED, izikhathi yokugcina ungcono isilinganiso eziyishumi. Igama elithi ka ukusebenza esibekiwe amadivayisi ukukhanyisa ezisebenzisa ukukhanya-likhipha diode thyristor, kuyinto iminyaka eyishumi ukukhanya okuqhubekayo. Amandla ukonga uma usebenzisa LED, ziqhathaniswa LDR yisilinganiso esingu-50%, uma kuqhathaniswa no esikhipha - 85%.

Okuphuma ukukhanya diodes yesimanje ungase ancintisane IPF futhi HPS (futhi DNaZ). Lesi sibalo ilingana 150 LM / W. Isikhathi payback ama LED - iminyaka 2-3. Ngemva kwalokho, asele iminyaka eyishumi, wonge 85% kagesi idliwe inyanga ngayinye.

LED. izici

LED, okuyinto izici akuzona analogue eliphansi, babe izinzuzo ezilandelayo:

• enkulu ekwakhekeni LED asetshenziswa ingilazi, ngakho ukhanyisa Isibani lolu hlobo babe ukuqina okusezingeni eliphezulu, vibration ukumelana nokwethembeka;
• LED amelana voltage iyehla iyenyuka futhi kudle 0.4-0.6 A kuphela;
• Thyristor LED usebenza ngempumelelo ezimweni ezimbi kakhulu, ngisho okushisa aphansi kakhulu.

Ukuze uqalise LED, kudinga ngempela eqolo diode ibhuloho, okubangela intengo ukukhanyisa ngaphambilini kwaba ngempela overpriced. Abakhiqizi ixazululwe le nkinga. Umdwebo wokuhlelwa kwendikimba kushintshiwe futhi esikhundleni thyristor triac dimmers isetshenzisiwe. Umphumela waba kudivayisi ehlanganisa thyristors ezimbili ezixhunywe isiqeshana parallel, counter kusho. Ngenxa ukuthi lokhu kwakwenqatshelwe, isidingo ibhuloho diode engekho namuhla. Lesi sinqumo luholele ekutholakaleni kwemikhiqizo eshibhile futhi khudlwana ezingeni ukuphepha kanye nekhwalithi izimpahla ngesisekelo the thyristors.

Thyristor Loluhlelo kabanzi asetshenziswe ekukhiqizeni amanye amadivayisi ukukhanyisa. ukuphila isikhathi eside yayo, ukuthembeka kanye usizo sokujabulisa abathengi, njengoba Chandeliers namanye amadivayisi nge LED-okukhanyisa akuyona kuphela ukonga, kodwa futhi ukubukeka enhle kakhulu.
