Why are there three lines for the controller of the LED light string? What are they?
- The LED pipe positive string is connected with 4-5 1K2W resistance strings, and the other end of the resistor is connected with the common positive pole of the controller. LED tube controller's direct bright output (Huang Xian), if the LED tube brightness is not too bright, minus a resistor. Remember not to short-circuit, short-circuit, burn out the controller. The less string LED, the more resistance string.s
How do you connect the LED lights?
- LED lamp can string together end to end, with more than 24 fluorescent lamp series, bulb lamp with 5X1W5 lamp series, and 6 series and 14.s
Who knows how the controller of outdoor LED lights can be protected against water?
- You can use the plastic wrap, mouth down, so even if again under the rain is not bad. Or glue the entire controller to the point where the water is likely to enter the water.s
Low voltage LED lamp string resistance is how to count, there is no formula?
- In general, LED lamps need constant current to drive, and the voltage may be adjusted according to the aging degree of the LED lamp.s
Rated voltage of LED lamp string
- When normal luminescence, each LED voltage drop is more than 2 volts, the current is about 15mA, to use 220V direct current should be connected in series with nearly one hundred led, or in the LED circuit series resistance, so that the series circuit current is about 15ma.s
What is the connection distance of the LED light string?Be specific
- When the installation must be installed according to the manufacturer's requirements, do not let the LED lamp string overload operation. I use the Zhongshan Greenman, which has detailed instructions, easy connections
What is the principle of the LED series?
- LED string:Light emitting diodes, referred to as LED, are made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.s
I want to do a string of LED lights that can use batteries. About 55 or so. The lights are 5MM blue. How can I work? Urgent urgent!!
- You can use the 4~6V battery, through the 4W, 2~3 Europe (6V with 3 Euro, 4V with 2 Euro) current limiting resistor, to the LED lamp power supply. The parameters of each lamp are: 3V, 20MA, in parallel (polarity). If you don't quite understand, you can also ask a science and engineering student (preferably a teacher) to help.s
