Cotton Ball String Lights Led Holiday Lights For Home Decoration

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?: 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: The color temperature of LED light string: Light source temperature is different, light color is also different:The color temperature is below 3300K, the color is red, and gives a warm feeling. There is a sedate atmosphere and a warm feeling.The color temperature is in the middle of 3000--6000K, and there is no obvious visual psychological effect in this hue, and there is a refreshing feeling. It is called neutral color temperatureColor temperature exceeds 6000K, light color slants blue, give a person with cool feeling, commonly referred to as cool color temperature.

Q: 220vled water lamp string how to connect, that is, 220 of the electricity: The time of the water lamp is controlled by adjusting the capacity value of the capacitor.

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: Section LED lantern, no controller, can shine principleTwo now reduced brightness string string: 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.

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: 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: 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.

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
