If the LED surface mount light keeps flashing, where is the problem?

There are probably two situations where this problem occurs:
1. Are your power plugs and sockets compatible and confirmed to be functioning properly? Please try replacing the plug or socket to check if the power supply is normal;
2. If there is still a "flash", it may be a problem with the power driver. It is possible that the output voltage of the driver is not consistent with the driving voltage required by your LED strip (you can test whether it matches or understand the driving voltage required by your strip). It is also possible that the power driver is damaged internally. Please try replacing it with a matching driving power supply;
Note: If your light strip is connected directly to 220V mains and flickers, common causes include a failed AC-to-DC converter inside the high-voltage plug, poor plug contact, or excessive voltage drop along the strip; check them one by one, starting with a matching replacement driver.
LED strip lights require a DC constant voltage power supply.
If equipped with an AC transformer, it will flash.
LED surface mount lights, also known as SMD or surface mounted light-emitting diodes, are packaged for production and can be operated using automatic surface mount machines,
The main models include 0402.0603.0805.1206.3528.3020.05.050.3014.5730, etc
Precautions for SMT LED
1. Clean and do not use unknown chemical liquids to clean the patch LED: Unknown chemical liquids may damage the patch LED. When cleaning is necessary, follow the official instructions for the specific model — do not immerse by default; where the datasheet permits, wipe with alcohol and let it dry naturally before use.
2. Moisture proof: To prevent the product from absorbing moisture during transportation and storage, the packaging of SMD LEDs is made of moisture-proof aluminum bags, which contain desiccants and humidity cards. The desiccants mainly control the humidity inside the packaging bags, while the humidity cards mainly monitor the humidity inside the packaging bags.
3. Storage: keep the packaging sealed; storage conditions (temperature, humidity, sealing and shelf life) are subject to the datasheet of the specific model.
