Hi Guys,
I would like to back light a 55" flat screen TV by placing strip LEDs around the rear of the cabinet to reflect off the wall where the TV is mounted. I have 4 one meter strips of sixty blue LEDs which should do the job. The strips were purchased from Hobby King and are labeled "Turnigy Power Systems". Each strip is rated with a VF of 12 volts and an IF of 400mA.
I have successfully used these strips many times by cutting them in multiples of 3 LEDs, splicing, etc. for lighting model airplanes with great success, but I was usually working with one strip of 60 or less LEDs. My dilemma in this application is: Should I power each strip individually from a common 12 Volt supply capable of 1600 mA, or can I connect the strips in series from the supply? If I choose the latter (preferred), I'm thinking I need to increase my power supply to 48 Volts at 400mA.
Is my thinking correct, or am I missing something? I would appreciate any comments or suggestions, and thanks in advance!
Bob
