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: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: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:220vled water lamp string how to connect, that is, 220 of the electricity
The triode acts as a switch in the circuit, and when the circuit is through, the left LED is first lit. The base is connected with a capacitor to connect the collector of the next triode.
Q:How do you connect the LED lights?
Connect the first LED positive pole to the negative electrode of the second LED and then connect the first LED negative pole with the second LED positive pole to the power supplyConnect the positive pole of each LED with the positive pole of the positive electrode, and then connect to the power supply. This is the parallel connection
Q:What is the principle of the LED series?
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: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:Low voltage LED lamp string resistance is how to count, there is no formula?
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.
Q:The number of lights in the LED string
15 lights, 30 lights, and 60 lights refer to the LED band. How many LED components are welded per meter length?
Q:Who knows how the controller of outdoor LED lights can be protected against water?
You can use the plastic wrap, mouth down, so even if again under the rain is not bad. Or glue the entire controller to the point where the water is likely to enter the water.
