Скачать или смотреть Detailed Q&A description of various interfaces and accessories for holiday decorative lights?

1. Common interface types
Q: What are the commonly used power interfaces for holiday decorative lights?
A:
Two-pin plug: The most basic non-polar plug, mostly used for low-voltage LED light strings.
Three-pin plug (with grounding): Used for high-power decorative lights (such as outdoor lighting) to enhance safety.
USB interface: Suitable for small lighting (such as desktop decorative lights), can be powered by a power bank.
Waterproof interface (IP44/IP65): Common for outdoor lights, equipped with rubber sealing rings, rainproof and dustproof.
Q: What are the connection interfaces between light strings?
A:
Snap-on connector: Quick plug-in design, common in LED light strings, male and female.
Threaded knob interface: Used for outdoor lights, locked by rotation to enhance waterproofness.
Magnetic interface: Used by some high-end decorative lights, easy to disassemble and adjust the position.

2. Core accessories and functions
Q: What are the accessories for controlling the effects of decorative lights?
A:
Controller (remote control/timing): supports flashing mode, brightness adjustment, timer switch (such as RF remote control or Wi-Fi smart control). Extension cord: waterproof extension cord is used outdoors, usually 1-10 meters in length.
Adapter: Convert different interfaces (such as USB to DC plug).
Q: What accessories are needed for installation and fixation?
A:
Plastic tie/hook: fix the light string on the railing or tree trunk.
Suction cup bracket: suitable for glass or smooth surface.
Grounding nail: fix the outdoor lawn light to prevent tipping.

3. Voltage and power adaptation
Q: How to choose the adapted voltage?
A:
Low-voltage lamp (12V/24V): needs to be used with a transformer, suitable for LED light string, and has high safety.
Mains power (110V/220V): plug in directly for use, and pay attention to waterproofing and insulation.
Q: Will connecting multiple sets of light strings cause overload?
A:
The total power needs to be calculated (single string power × quantity) to ensure that it does not exceed the nominal load of the power supply or controller (e.g. a 10A controller supports up to 1200W).
LED light strings have low power consumption and can be connected in series in multiple groups; incandescent lamps need to be used with caution.

IV. Precautions for outdoor use
Q: How to distinguish the waterproof levels of outdoor lights?
A:
IP44: splash-proof (suitable under eaves).
IP65: spray-proof (can be directly exposed to rain).
IP67: can be temporarily immersed (such as pool lights).
Q: How to avoid short circuits?
A:
Check the sealing of the interface to avoid exposed copper wires.
Wrap the connection with waterproof tape.
Install a leakage protector in the distribution box.
V. Troubleshooting
Q: What should I do if part of the light string does not light up?
A:
Check whether the faulty bulb is loose or burned (the spare bulb can be replaced).
Test whether the connection interface is oxidized (clean the contacts with alcohol).
Q: How to solve the problem of remote control failure?
A:
Replace the battery and make sure the receiver is not blocked.
Reset the controller (refer to the pairing steps in the manual).
