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:LED lights string broken, how to repair?

LED lights string broken: you can check one by one, which is bad, which change.

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:Section LED lantern, no controller, can shine principleTwo now reduced brightness string string

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: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

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: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!!

If it is a general common blue LED working current is 20 mA, voltage of about 2.5V can be lit, the battery power can be used in parallel, the benefits of this connection is one of the damage does not influence the normal operation of other LED. And each LED string to a current limiting resistor, LED protection lamp, prolong life, calculation formula of the resistance for V / 0.02A=: voltage current resistance: 3V, battery powered =3 / 0.02=150. You want to supply 55 LED batteries to work together, the total current is up to 0.02x55=1.1A, i.e. 1AH (ah) capacity of the battery can work 1 hours or so.

Q:Led full-color light string and how to control wiring

Four line color data signal exposed lamp connected: lamp electrode with GND surface control signal is connected with the DAT clock with CLK

Q:How do you connect the LED lights?

LED lamp can string together end to end, with more than 24 fluorescent lamp series, bulb lamp with 5X1W5 lamp series, and 6 series and 14.

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.
