Q: How do you connect the LED lights?: A series of even parallel. Are not clear, boss, you want to use LED do what?There is a gap, which is the positive pole of the LED (usually the long foot is short and the foot is negative)

Q: Hanging on the tree string lights, each one is 10 meters long, with a controller, I asked the factory with the AB protection, but the manufacturers say that only do the general anti rain, no water, even the rain stop, I want to use plastic wrap, don't know? Which expert can give advice and advice? emergency: Now the market has launched a LED string lamp controller. Professional rainproof. You should be able to buy it at the big mall!!!

Q: The color temperature of LED light string: Refers to a standard blackbody heating, the temperature rises to a certain degree when starting from the color red - Orange - red - white - blue, gradually changed, a light source and the blackbody with the same color, we will at the time of the absolute temperature blackbody called the color temperature of the light source.

Q: The number of lights in the LED string: In general, 1210 specifications of the band is 60 LED per meter, 5050 specifications of the band is 30 LED per meter, the special has 60 LED per meter.

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: 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: Example: if I want to do a 40 head low voltage lamp string, do 10 lights, 1 loop, transformer is 150MA, then how can I calculate the resistance? The grid is 60 Hz of China's power grid! Give a formula, and then count the examples. What is it?! Thank you: Diode products cannot be calculated by resistors.

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's the price of the LED light string?: On the market now, 3014 of 11lm is often priced at between 0.13-0.16. The lamp has stable performance, good brightness, low luminous decay, and color index is much better. 600x600LED panel light 360 beads, which is about 53 yuan.Are basically using 11x23 or 11x26mil chip, chip /pcs lamp about a penny.
