Christmas is coming! What are you going to need to decorate your house for party? Surely you won't miss the Christmas lights. Not only it brights up your home, everyone in the family instantly feels the spirit of Christmas - the love and the warmth.

Features:
change light string:
8 Lighting Modes, Choose your favorite light mode! you can select any mode what you like (Combination, In waves, Sequential ,SLO GLO, Chasing / flash ,Slow fade ,Twinkle/flash ,Steady on)

Usually for the following purpose: Christmas tree or Halloween Illuminations, Showcase or Window displays, Restaurants or Bar Decorations, Home or Garden Decorations, Wedding, Birthday or party Illuminations, etc.

Q: The top LED lights always burn the bulb in series: A simple circuit based on resistance current limiting can only be adjusted with current resistance.

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: How do you connect the LED lights?: Connect the bottom edge of the triangle symbol to the high voltage and the sharp angle to the low voltage. The bottom edge of the next LED is connected with a sharp angle

Q: How does the LED light string flash?: Because of the special volt ampere characteristics, LED can not use constant voltage driving mode, but is driven by cross flow. The direct drawback of cross flow drive, however, is heat. So people invented the drive mode of pulse drive. For example, 0.5 seconds per second, so that the amount of heat in the LED is reduced by half. Then turn the frequency up to 100 times per second, lighting for 0.005 seconds each time. At this point, the power of the LED is not the same, and people do not feel blinking. What's more, in this driving mode, an approximate cross flow drive (that is, the current is not necessarily precise) can be simplified, which simplifies the drive circuit (the precise cross flow source is very complex)

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: 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: Rated voltage of LED lamp string: You are the light string and see how much you a lamp, the lamp voltage for LED in 3.0-3.4V, for intermediate values of 3.2V, N=220/3.2=68.75 so many beads. In fact, we are in terms of LED is a DC device, there is no voltage rating, mainly to see his current value, the work must be steady flow. The power 0.06W LED current is 20MA, the power 0.2W LED current is 60MA, the power is 0.3W, the LED current is 100MA, the power is 1W, the high power LED current is 300-350MA, and so on in turn, ah, I=P/U

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: LED lights string broken, how to repair?: LED lights string broken: you can check one by one, which is bad, which change.

Q: How much is the voltage across the 20 LED lamps in series?: Don't know what kind of LED, if it is ordinary bright LED words, according to different colors, the rated voltage between 3.6-3.8V (current allowable level <20mA), you can be calculated according to the amount of estimates, as long as the control current should not exceed 20MA no problem

Q: What are the power connections for the LED light string?: LED lamp string power connection method: LED light string, general voltage is DC 12V, so need to use switching power supply, power supply according to the size of LED light string and connection length to decide
