Q:How much is the voltage across the 20 LED lamps in series?
LED lighting general LED lamp belt voltage, conventional specifications are 12 volts and 24 volts, if it is 12 volts, that voltage is 420 volts, if it is 24 volts, that is 840 Volts
Q:Why are there three lines for the controller of the LED light string? What are they?
Common positive (red line +) is the positive pole for each street lampThree road cycling (blue line) this four lines are respectively connected with the four colors of LED tube anode side run. When the positive pole is connected to the common cathode, remember that the resistor must be connected first to connect to the positive electrode of the LED tube. The bright output (white) is the word to make it bright
Q:How does the LED light string flash?
LED because of its special structure, frequent startup does not reduce its service life, but high temperature can significantly shorten its life. So cooling is important for LED.
Q: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!!
If it is a general common blue LED working current is 20 mA, voltage of about 2.5V can be lit, the battery power can be used in parallel, the benefits of this connection is one of the damage does not influence the normal operation of other LED. And each LED string to a current limiting resistor, LED protection lamp, prolong life, calculation formula of the resistance for V / 0.02A=: voltage current resistance: 3V, battery powered =3 / 0.02=150. You want to supply 55 LED batteries to work together, the total current is up to 0.02x55=1.1A, i.e. 1AH (ah) capacity of the battery can work 1 hours or so.
Q:220vled water lamp string how to connect, that is, 220 of the electricity
On the way of C1, R1, L1, R2 varistor, the primary power supply filter circuit, can input the instantaneous pressure filter, C2, R2, C4, C3 step-down circuit, L2 varistor and filter circuit is composed of rectifier, the filter, which can effectively protect the LED by high pressure breakdown.
Q:LED lights string broken, how to repair?
Connect the electricity. Can be shorted one by one. It's shining. This is just short of bad beads.
Q:What's the average luminous current of an ordinary LED lamp string?
If the lamp light current series is their rated current,
Q:The top LED lights always burn the bulb in series
Do not know what kind of drive you are, try to reduce the current of LED, do not exceed the rated operating current of LED on the line. The method of reducing current is related to drive circuit, and the current limiting method is different for different circuits.
Q: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.
Q:Who knows how the controller of outdoor LED lights can be protected against water?
If you don't have a shell, it's an open controller, so you can make a waterproof plastic lid and make it waterproof at the front of the O loopYou can refer to the LED waterproof flashlight for inspiration!
