Q: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 problem
Q:LED lights string broken, how to repair?
LED lights string broken: you can check one by one, which is bad, which change.
Q:The top LED lights always burn the bulb in series
A simple circuit based on resistance current limiting can only be adjusted with current resistance.
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
There are grades of waterproof and dustproof, and the methods from 0 to 9. are different!I think you should use, can prevent the rain, and shallow water immersion!This is easy to handle. When the controller is made, if it has a shell, touch 703 glue at the joint! General circuits are frequently usedIn fact, many LED production plants have LED filling glue and waterproof!
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!!
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.
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: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:How does the LED light string flash?
What kind of light? What about the flash?If you are talking about the pulse drive mode of LED, then it is for heat dissipation and energy saving.
Q:Why are there three lines for the controller of the LED light string? What are they?
The LED pipe positive string is connected with 4-5 1K2W resistance strings, and the other end of the resistor is connected with the common positive pole of the controller. LED tube controller's direct bright output (Huang Xian), if the LED tube brightness is not too bright, minus a resistor. Remember not to short-circuit, short-circuit, burn out the controller. The less string LED, the more resistance string.
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
If you direct the transformer to the LED lamp power supply, the life of the LED lamp will be affected, far less than the nominal value.
