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: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 is the connection distance of the LED light string?Be specific

LED light string connection distance: in general, the 3528 series of LED lights belt, its connection distance is the longest 20 meters, 5050 series of LED lights string, the longest connection distance is 15 meters

Q:The number of lights in the LED string

15 lights, 30 lights, and 60 lights refer to the LED band. How many LED components are welded per meter length?

Q:The top LED lights always burn the bulb in series

If the regulator is powered, it is necessary to lower the voltage

Q:Rated voltage of LED lamp string

LED is a light emitting diode. It can be used for AC and DC. Because of the reverse breakdown voltage of LED, it is very voltage. The single LED current can be connected by a ammeter to the inside. If you look at the rated current of LED, you should look at it

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!!

55, it is blue, blue and white as the power is too large, large power consumption, even in parallel connection, the voltage of 3V certainly do not move with the battery, just to be able to provide 4.5V voltage, and three batteries of 5 words for a while no electricity, regulated power supply with advice, use parallel to, from the 3V voltage can be gradually increased, the brightness is just perfect, too high voltage lamp

Q:How do you connect the LED lights?

A series of even parallel. Are not clear, boss, you want to use LED do what?There is a gap, which is the positive pole of the LED (usually the long foot is short and the foot is negative)

Q:How does the LED light string flash?

What kind of light? What about the flash?If you are talking about the pulse drive mode of LED, then it is for heat dissipation and energy saving.

Q:What are the power connections for the LED light string?

If you do not want to use a power to control each LED lamp string, can switch power to buy a relatively large power for the total power supply, then put all LED light on the input power (all parallel wire size is not enough, can also extend) unified by the total power switch.
