Q:Performance and characteristics of LED lamp string
1.LED light string is good. The colors are red, yellow, green, blue, white, warm white and so on;2.LED lamp has the advantages of convenient installation, after one-time injection waterproof, waterproof grade IP65, installation of plastic card, do not need any accessories, you can direct the word in the hole and fixed installation;
Q: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.
Q:Led full-color light string and how to control wiring
Three line full color exposure lamp data signal two, the controller needs two wire negative electrode control, GND signal connected to the DAT surface
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: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.
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:The top LED lights always burn the bulb in series
Do not know what kind of drive you are, try to reduce the current of LED, do not exceed the rated operating current of LED on the line. The method of reducing current is related to drive circuit, and the current limiting method is different for different circuits.
Q:What's the average luminous current of an ordinary LED lamp string?
General LED patch to 0.2W, 0.5W, 0.2W lamp current is 60mA, 0.5W beads 150mA,
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:Why are there three lines for the controller of the LED light string? What are they?
65 of the LED tubes are connected with 3-4 resistors. One end of the resistor is connected to the positive electrode of the LED, and the other end of the resistor is connected to the common anode of the controller. The blue wire is attached to the negative electrode of the LED tube.
