Q:What's the average luminous current of an ordinary LED lamp string?

If the lamp light current series is their rated current,

Q:LED lights string broken, how to repair?

As an emergency treatment, you can also short-circuit the open circuit of the LED lights. Used to restore normal work.

Q:What is the connection distance of the LED light string?Be specific

The connection distance is 15 meters. If the connection distance is exceeded, the LED light string is easy to heat, and the service life of the LED light string will be affected during use

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: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: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

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.

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!!

55, it is blue, blue and white as the power is too large, large power consumption, even in parallel connection, the voltage of 3V certainly do not move with the battery, just to be able to provide 4.5V voltage, and three batteries of 5 words for a while no electricity, regulated power supply with advice, use parallel to, from the 3V voltage can be gradually increased, the brightness is just perfect, too high voltage lamp

Q:The color temperature of LED light string

Light source temperature is different, light color is also different:The color temperature is below 3300K, the color is red, and gives a warm feeling. There is a sedate atmosphere and a warm feeling.The color temperature is in the middle of 3000--6000K, and there is no obvious visual psychological effect in this hue, and there is a refreshing feeling. It is called neutral color temperatureColor temperature exceeds 6000K, light color slants blue, give a person with cool feeling, commonly referred to as cool color temperature.

Q: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 bright

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

In general, LED lamps need constant current to drive, and the voltage may be adjusted according to the aging degree of the LED lamp.
