LED rasvjeta DIY
#2
Iako sam svestan da se dovodim u verovatno neprijatan polozaj
mislim da taj modul i nije bas najbolje resenje. Brzom analizom
vidi se da je u slucaju da je pad napona na LM 5V struja oko
60mA. Ako pad napona ode na 20V struja opada na oko 40 mA.

Pravo da vam kazem ja bi konstantni izvor struje odradio sa nekom
starom mrcinom tipa BU208A pretvorenom u darligton, ili jos bolje
sa fetom tipa recimo IRFBC20
