LED lights with 80V induction, string, how many ohm resistance?
Generally speaking, LED lamp with power is 1210 4.8W per meter, i.e. constant current per meter is 0.4A, LED lights a few meters with the load current and so on; LED lamp with power is 5050 7.2W per meter, namely constant current per meter is 0.6A; 0603 LED lamps with power is 1.5W per meter, namely constant current per meter is 0.125A.
Understanding of the LED street lamp with a constant current per meter, you can accurately grasp the power output current problems, to avoid the output current is too large to cause LED breakdown phenomenon. Special note: LED lights with power use, we must pay attention to voltage, current, power these three factors, are indispensable
LED lights with LED lights are generally the largest 20mA, so the power supply current must be guaranteed not greater than this current, which is LED drive power needs to solve a difficult problem. Many friends in use only pay attention to voltage, and ignore the current specification size, this often causes the power supply current is too big and LED breakdown, cause LED lamp belt damage. Power supply generally has a rated voltage, rated current and rated power. We choose the power supply, we must consider the good load (LED light belt) power and rated current is how much, so that it is convenient to choose the right power supply.
