Q:How much is the voltage across the 20 LED lamps in series?: Each LED is about 3V, and the 20 series is 60V

Q:What's the average luminous current of an ordinary LED lamp string?: If the lamp light current series is their rated current,

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: Different LED number of LED light band price is different, and this is also to distinguish LED lamp belt price is an important factor.

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!!: 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:Led full-color light string and how to control wiring: Four line color data signal exposed lamp connected: lamp electrode with GND surface control signal is connected with the DAT clock with CLK

Q:Why are there three lines for the controller of the LED light string? What are they?: The four cycles are green, blue and white, and the answer is almost the same as that on the top. But the three colors are strung together

Q:Example: if I want to do a 40 head low voltage lamp string, do 10 lights, 1 loop, transformer is 150MA, then how can I calculate the resistance? The grid is 60 Hz of China's power grid! Give a formula, and then count the examples. What is it?! Thank you: If you direct the transformer to the LED lamp power supply, the life of the LED lamp will be affected, far less than the nominal value.
