What is the minimum number of light bands?
General LED lamp belt is 12V, 3 beads and a resistor in series, a lamp minimum starting voltage of about 3V, almost 3 9V, although it is lit up, but the brightness is very low, want to achieve higher brightness or to 12V, then 9-12V lamp belt between the lights. Of course, some factories also have 24V, and the same principle.
LED lights with 12V meters, there are a variety of power, the common 5W to 20W, such as: 3528LED, 30 led per meter, power per meter 2.4W; 60 led per meter, 4.8w per meter. 5050led, 30 led per metre, 7.2W per metre, 60 led per metre, 14.4w per metre. Led band power calculation method: power is the measurement of energy transfer rate, in dc...
