Q:SMD LED lamp working voltage?
LED is a light emitting device of low voltage, low current, low power forward current general patch type LED when using (IF) 20MA, (VF) 1.8-2.5V, voltage of red green and blue (VF) voltage is 3.0-3.6V. Different manufacturers also have small differences, so first of all, look at the color,Of course. The multi chip assembly in high voltage chip together, some current: 1 watts, 1 watts and above. A wide variety of varieties, as follows:
Q:How many voltages and how many W drivers are used in series and parallel connection with 20 1W patches LED?
In series, the voltage is 20 times the rated voltage, in parallel, the voltage is rated voltage, but in tandem, a LED is broken, it is not bright, so it is recommended not to use it.
Q:Patch LED manual welding, how can welding not burn lights?
If the power of the lamp, because heat high power do very well, so not good welding, the temperature at the highest (300 degrees), the use of horseshoe iron head, not waiting to solder, because the heat is very powerful, quick action.
Q:What does "1210" mean in patch LED?
1210 represents the size of the LED package specification (size, specification), and represents the length and width of the resistanceSpeed adoption!!!
Q:Indoor full color LED display module and LED what is the difference between a full color?
Indoor full color LED display module and LED chip has three full color difference. The first part: Second: third light emitting display module: maintenance: LED full color display is not easy to maintain. LED full color patch is relatively easy to maintain.
Q:Is the forward voltage drop of the patch LED too large or too small?
The pressure drop in the normal range is generally better. The smaller the pressure drop, the lower the power dissipation. The more you save the electricity bill.But not to say that the smaller the better, not in the normal range of low pressure drop products may be defective.In addition, the uniformity of the LED pressure drop is also important.
Q:How does the LED patch lamp differentiate between positive and negative poles?
Because the LED open threshold is about 1.5-1.8V. It is possible that the voltage supplied by the digital multimeter does not activate it. So look at the sign. Patch LED (SMD LED), the green point of negative, relative to the positive.
Q:LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?
LED patch lamp with 3528-60 beads should be 4.8W/ meters.Because the LED light belt is made according to the manufacturer's standard, the parameters are different, and the parameters of the LED lamp belt and the method of use are best connected with the manufacturer's confirmation. Some common parameters are given here for reference only
Q:Led lamp and Led what is the difference between the two patch! Ask for detailed explanations of the differences!
First of all, I want to say, in the same light emitting chip case, two is not what were, just a different process is a DIP plugin, a SMD patch process, the 3 floor of the right, just some high grade patch.
Q:Patch LED light does not flash, why?
There are three main reasons:1, the temperature is too high, resulting in LED lights, dead lights.2, do not do anti-static measures, electrostatic breakdown chip, resulting in damage to the LED light.3, the use of LED lamp quality is too bad, the purchase price reasonable LED lights
