LED lighting in the LED lights with quality recognition skills

1, the flexible LED light belt is the use of FPC assembly circuit board, with patch LED assembly, so that the thickness of the product is only the thickness of a coin, does not take up space; The general specifications are 30cm long 18 LED, 24 LED and 50cm long 15 LED, 24 LED, 30 LED and so on. There are 60cm, 80cm, etc., different users have different specifications. And can be cut at will, can also be extended at will and the light is not affected. The FPC material is soft, can be bent, folded, wound arbitrarily, can be moved and expanded in three-dimensional space without breaking. It is suitable for use in irregular places and small Spaces, and because it can be bent and wound arbitrarily, it is suitable for any combination of patterns in advertising decoration.
2, LED hard light strip is assembled with PCB hard board, LED useful patch LED for assembly, but also useful in direct insertion LED
LED lighting technology is widely used in modern home, commercial and decorative fields, among which LED light strips are favored for their flexibility and energy saving characteristics. However, the quality of LED lights on the market is uneven, and it is crucial to master the skills of identifying high-quality LED lights.

We need to understand the basic types of LED lights. The Flexible LED light belt uses FPC (Flexible Printed Circuit) as an assembly circuit board, which has the characteristics of thin and flexible, and can adapt to various shapes and Spaces. Common specifications are 30cm, 50cm and other lengths, including different numbers of leds. Due to the characteristics of FPC material, this light belt can be freely bent, folded and wound, suitable for irregular space and advertising decoration. On the other hand, the LED hard strip uses a PCB hard board, which can be a patch LED or an in-line LED, which is easy to fix and process, but cannot be bent arbitrarily like a flexible light strip.

When identifying the quality of LED lights, there are the following key points:

1. Observe solder joints: high-quality LED strip adopts SMT patch process, solder joints are smooth and solder distribution is uniform, showing a circular arc. Inferior products have irregular solder joints and may have too much solder or tin tips, which is a sign of manual welding.
2. Check the quality of FPC: the copper foil of the copper plate is obviously protruding, which is easy to fall off the pad; Pressed copper is tightly integrated with FPC for greater durability. Observe whether the pad is firm and whether there is a risk of falling off.
3. Cleanliness: The surface of the lamp produced by the SMT process is clean, without impurities and residues. Hand-welded lamp strips may have stains and flux residue.
4. Packaging: Regular products will use anti-static coil trays and moisture-proof bags with clear labels, while low-cost products may lack these protective measures.
5. Labels and accessories: There will be printed labels on the packaging of the regular light belt, and the specifications and accessories are complete. Knock-off versions may only have printed labels and lack accessories.
6. Brand reputation: Choose a manufacturer with a good reputation. Choose our LIKELIGHT, the quality of our products is guaranteed, after-sales worry, provide project design.

When buying LED lights, in addition to the above skills, you can also refer to the user's evaluation and professional website recommendation.

The choice of LED light belt needs to consider its material, production process, appearance cleanliness, packaging details and brand reputation and other factors. Only in this way can we ensure the purchase of both beautiful and durable LED lights to meet a variety of lighting and decorative needs.
