how light 60 LEDs together in less than 9 V power?
i may want to make a film LED with 60 LEDs. i probally wire them in series, but how wure do it with a 9V battery. now in a belt for more I really I can not use a 9V battery. Not sure about any resistance i We know almost nothing about the LED and the energy they need. I would helpful.Here diagram is the link to the LEDs (20 red and 40 blue diffuse diffuse. thanks in advance
you need the Vf of each type. If not, look in line with the specifications of a similar unit. Then see how you can put in a chain of series in addition to about 7.6 volts. For example, if VF is 2.1 volts, you can put 3 in series, equivalent to 6.3 volts. That leaves 2.7 volts to the resistance. It is estimated the value of resistance as R = 2.7/IF, wherein if the direct current typical specification sheet. If SI is 20 m in this example, R = 2.7/0.02 = 135 ohms (150 use ohms) Now repeat the sequence as many times as you like, placing each string in parallel across the 9V battery. .
