FAQ

The top LED lights always burn the bulb in series
If the regulator is powered, it is necessary to lower the voltages
Why are there three lines for the controller of the LED light string? What are they?
Common positive (red line +) is the positive pole for each street lampThree road cycling (blue line) this four lines are respectively connected with the four colors of LED tube anode side run. When the positive pole is connected to the common cathode, remember that the resistor must be connected first to connect to the positive electrode of the LED tube. The bright output (white) is the word to make it brights
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 decides
Low voltage LED lamp string resistance is how to count, there is no formula?
In general, LED lamps need constant current to drive, and the voltage may be adjusted according to the aging degree of the LED lamp.s
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/Us
What is the principle of the LED series?
When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.s
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 problems
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!!
You can use the 4~6V battery, through the 4W, 2~3 Europe (6V with 3 Euro, 4V with 2 Euro) current limiting resistor, to the LED lamp power supply. The parameters of each lamp are: 3V, 20MA, in parallel (polarity). If you don't quite understand, you can also ask a science and engineering student (preferably a teacher) to help.s
