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: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:What is the principle of the LED series?
Led 2 polar tube inside chip oscillator circuit, and the general appearance led 2 polar tube without distinction, only connected to the power supply of two kinds of color turns light, 1 seconds, I bought the 5MM red, blue autoflash. From the appearance of the series, but not necessarily in series
Q:What's the price of the LED light string?
Frame and bottom plateLED panel light frame and bottom plate according to different material, its heat dissipation performance is not the same priceThere are differences. The price of the 6063 aluminum profile is about 50-80 yuan (the specifications are different and the prices are different).
Q:Led full-color light string and how to control wiring
Four line color data signal exposed lamp connected: lamp electrode with GND surface control signal is connected with the DAT clock with CLK
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:How much is the voltage across the 20 LED lamps in series?
LED lighting general LED lamp belt voltage, conventional specifications are 12 volts and 24 volts, if it is 12 volts, that voltage is 420 volts, if it is 24 volts, that is 840 Volts
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:How does the LED light string flash?
LED because of its special structure, frequent startup does not reduce its service life, but high temperature can significantly shorten its life. So cooling is important for LED.
