Q:The top LED lights always burn the bulb in series
If it is a constant current drive, there is a special adjustment element to adjust the current.
Q:What are the power connections for the LED light string?
If you do not want to use a power to control each LED lamp string, can switch power to buy a relatively large power for the total power supply, then put all LED light on the input power (all parallel wire size is not enough, can also extend) unified by the total power switch.
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?
If the lamp light current series is their rated current,
Q:Who knows how the controller of outdoor LED lights can be protected against water?
If you don't have a shell, it's an open controller, so you can make a waterproof plastic lid and make it waterproof at the front of the O loopYou can refer to the LED waterproof flashlight for inspiration!
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:Performance and characteristics of LED lamp string
1.LED light string is good. The colors are red, yellow, green, blue, white, warm white and so on;2.LED lamp has the advantages of convenient installation, after one-time injection waterproof, waterproof grade IP65, installation of plastic card, do not need any accessories, you can direct the word in the hole and fixed installation;
Q:How does the LED light string flash?
LED because of its special structure, frequent startup does not reduce its service life, but high temperature can significantly shorten its life. So cooling is important for LED.
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 triode acts as a switch in the circuit, and when the circuit is through, the left LED is first lit. The base is connected with a capacitor to connect the collector of the next triode.
