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.
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:Led full-color light string and how to control wiring
5 line DMX512 full color string, 2Po, 2 access, and access control site
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 color temperature of LED light string
Refers to a standard blackbody heating, the temperature rises to a certain degree when starting from the color red - Orange - red - white - blue, gradually changed, a light source and the blackbody with the same color, we will at the time of the absolute temperature blackbody called the color temperature of the light source.
Q:LED lights string broken, how to repair?
As an emergency treatment, you can also short-circuit the open circuit of the LED lights. Used to restore normal work.
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:Performance and characteristics of LED lamp string
1.LED lamp string can handle perforation lamp string processing;2.LED lights string may through seven colors and full-color controller to achieve colorful jump, gradient, monochrome, full-color, fluttering and other effects.
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: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.
