Pomoc oko povezivanja LED dioda

Submitted by Aquamaniac on Wed, 22/05/2013 - 11:22

Pozdrav svima,ovo mi je prvi post na ovom forumu,pa mi ne zamerite ako sam fulao podforum...
Kupio sam nekoliko komada ovakvih LED dioda,pa mi je potrebna preporuka za adapter i pomoc oko povezivanja.
Ako je ikako moguce,hteo bih da povezem 5 ovakvih LED dioda na jedan adapter,pa me zanima koji bi mi preporucili,od koliko volti i ampera?
Prema karakteristikama LED diode,logicno pretpostavljam da bi za tako nesto trebao adapter ili od 16 ili od 18v i od 3.5A...ispravite me ako gresim?
Sto se tice povezivanja,da li bih ih vezivao paralelno ili redno?
Naravno,uz ovakve LED diode idu i hladnjaci koje sam takodje kupio...

Karakteristike LEd diode:
Forward voltage: 3.2-3.6v
Forward current: 700mA
Power: 3W
back ward voltage: 5v

Kao i svaka druga dioda i LED ima katodu i anodu. U tvom slucaju najzgodnije je da ih povezes na red ( katoda jedne na anodu naredne). Tako ces posle ovog povezivanja imati jednu anodu i jednu katodu koje treba povezati na izvor jednosmernog napajanja ( katoda na minus pol, anoda na plus pol ).Taj izvor treba da izdrzi najmanje 700mA a pozeljno je i vise ( npr 1A). Napon ovog izvora treba da bude 5*( 3.2-3.6V) dakle od 16 do 18V. Za ovu namenu bi verovatno dobro dosao neki izvor napajanja za laptop navedenog napona i najmanje struje 0.7A.
Vazna napomena: ovakve diode je obavezno montirati na pogodno rashladno telo ( hladnjak) jer se bez njega greju i mogu da "pregore" usled visoke temperature.

pročitao sam ove postove pa da se nadovežem
zanima me šta bi se desilo i koliki bi trebao napon i struja pri paralelnom povezivanju ovakvih led dioda

Kod paralelne veze napon ostaje isti (3.2 do 3.6V ) , a struje se sabiraju (0.7 plus 0.7 plus 0.7 plus 0.7 plus 0.7) sto iznosi 3.5A .
