hi
can anyone help me in identifing this circuit ?
http://www.ebay.com/itm/LED-Super-F...4153983?pt=US_Light_Bulbs&hash=item20c599f1ff
it is a led lamp.. it takes 10-14 volts and has 24 leds ..
can anyone tell me how the led and resistor is arranged ? it seems ut has 3 series leds in a parrallel string of 8.. and a single resistor to control overall current.. ewhat is the value of led ? seems like 200 M ohms ..with 1 % accuracy..
i have red that these leds require 2.9 to 3.5 volts to work with full brightness at 3.5 v @ 20 mA..
how has the resistore been chosen in the above case ?
i want to make one like it..
