Q:Low voltage LED lamp string resistance is how to count, there is no formula?
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.
Q:What is the principle of the LED series?
When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.
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:Who knows how the controller of outdoor LED lights can be protected against water?
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 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: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 lights string broken, how to repair?
LED lights string broken: you can check one by one, which is bad, which change.
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: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:220vled water lamp string how to connect, that is, 220 of the electricity
The time of the water lamp is controlled by adjusting the capacity value of the capacitor.
