The power supply is the most important part of LED fluorescent tube , if you choose properly , LED fluorescent tubes properties not only can not play , not even normal use.

Matching LED power and light board

Some customers to design light board, find the power, find it difficult to have a proper power supply or too much current, the voltage is too small ( eg I> 350mA, V <40V); either current is too small, the voltage is too high ( eg I < 40mA, V> 180V), resulting in a severe fever, inefficient, or the input voltage range is not enough. In fact, choose a string and pick the best way, plus the voltage and current on each LED are the same, but the effect of the power supply was able to play the best performance, so the best way is to communicate and power supply manufacturers, tailored.

LED operating current

General LED is rated operating current 20 mA, and some plants beginning to use the maximum design 20 mA. This current work is actually very serious fever, after numerous comparison tests, designed to be 17 mA is ideal.

LED operating voltage

General LED ‘s recommended operating voltage is 3.0-3.5V. After testing, most of the work at 3.125V, 3.125V calculated according to the formula so reasonable. best led headlights http://bestledheadlight.com/

LED lamp series-parallel plates with wide voltage

For an LED lamp in a relatively wide range of input voltage (AC85-265V), LED lamp series and parallel plates is very important. Due to the current power generally non -isolated step-down power, wide voltage requirements, the output voltage does not exceed 72V, the input voltage range of 85-265V can be reached, that is, the series number no more than 23 series and parallel count not too much, otherwise the operating current is too large, severe fever, and is recommended for 6, 8 and 12 and the total current is not more than 240 mA as well.
