Led supermarket in led high bay lights .

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: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: 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: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:Section LED lantern, no controller, can shine principleTwo now reduced brightness string string: LED string:Light emitting diodes, referred to as LED, are made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.

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:220vled water lamp string how to connect, that is, 220 of the electricity: On the way of C1, R1, L1, R2 varistor, the primary power supply filter circuit, can input the instantaneous pressure filter, C2, R2, C4, C3 step-down circuit, L2 varistor and filter circuit is composed of rectifier, the filter, which can effectively protect the LED by high pressure breakdown.

Q:The color temperature of LED light string: Generally speaking, the color temperature is not an indicator of the LED band, but many foreign customers will make a special request because of the use of the environment.

Q:How do you connect the LED lights?: Connect the bottom edge of the triangle symbol to the high voltage and the sharp angle to the low voltage. The bottom edge of the next LED is connected with a sharp angle

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.
