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

发布于: 2022-03-30 19:36

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 directly connected to 220V mains power and this problem occurs, it must be due to a broken AC to DC converter inside the high-voltage plug.
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, immerse the patch LED in alcohol and let it dry naturally for less than 1 minute at normal room temperature for 15 minutes before starting to 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. The storage packaging bag should be sealed and stored at a temperature below 40 ℃.

Frequently Asked Questions (FAQ)

1. Can I get free LED samples from Hongcheng Optoelectronics?

Yes. Dongguan Hongcheng Optoelectronics Co., Ltd. supports sample testing — you can verify electro-optical parameters, dimensions and soldering compatibility before placing bulk orders. To request samples, call +86 139 2571 4318 (WeChat same number) or email sales@led-hc.com with the model and quantity you need.

2. What is the minimum order quantity (MOQ)?

The MOQ for DIP (through-hole) LEDs is 1K (1,000 pcs); for SMD LEDs the MOQ is 3-5K, shipped in tape-and-reel packaging. The MOQ for customized models (special wavelength, brightness or voltage binning) is confirmed per custom solution. Please contact sales for an accurate quotation and MOQ for your model.

3. What are the lead times for samples and mass production?

Sample lead time is typically 3-4 working days; in-stock samples are usually shipped within 2 working days. Mass production lead time is typically 10-15 working days, confirmed according to order quantity and production schedule — please contact sales for an accurate lead time.

4. Are the products RoHS certified?

Yes. All Hongcheng LED diodes are RoHS and CE certified, made with A-grade chips, 99.9% pure gold wire bonding and high-temperature resistant encapsulant — anti-sulfuration and low light decay, meeting the environmental and reliability requirements of home appliance, automotive and industrial equipment applications.

5. Can voltage, wavelength, brightness or color be customized?

Yes. We support binning and customization of brightness, wavelength, voltage and color, and provide OEM services. Our product range covers 0201-5730 SMD LEDs, addressable RGB LEDs with built-in IC, side-emitting LEDs, and 2mm-10mm DIP LEDs, packed in vacuum moisture-proof tape and reel, suitable for automated SMT mounting and reflow soldering.

6. How do I get the product datasheet?

Every model has an official PDF datasheet (electro-optical parameters, dimensions, pad design, tape packaging and reliability test data) — 259 datasheets in total, all free to download with no login required. Browse the datasheet center (https://www.hc-led168.com/datasheets) by series, or download directly from each product page.

7. Is Hongcheng Optoelectronics a factory or a trading company?

Hongcheng Optoelectronics is a member of Guangyu Group — a professional LED diode source manufacturer based in Dongguan, Guangdong, China, with 20+ years of LED packaging experience. Factory-direct sales; over 50% of raw materials are imported from South Korea, Japan and Taiwan, China. Quality and lead time are controlled directly by the factory.
