How to distinguish the quality of LED strip lights
There are many styles of LED strip lights on the market. A large number of manufacturers say that the LED engineering line lights they make are of good quality, low price, long life, etc. There are also some high-priced "brand products". How do we go about it? To distinguish the quality of LED engineering line lights, what points should be analyzed? This issue has been specially collected by the editor to give you a lot of information.
First, look at the glue:
The serious yellowing phenomenon of LED strip lights after one year is because the glue materials are too poor. There are many low-quality glues sold in the name of waterproof PU glue on the market. They have poor waterproof performance and are prone to yellowing and darkening. Likewise, The price of it is very different from that of normal waterproof PU glue, basically the price difference is more than double.
The linear lights produced by regular LED strip light manufacturers use the patch process, solder paste and reflow soldering processes. Therefore, the solder joints on the line lamp are relatively smooth, and there is not much solder paste. The solder joints are arc-shaped and extend from the FPC pad to the LED electrode. However, the amount of solder in the solder joints of the knockoff version of the line lamp is uneven, with a round dot covering the solder legs, and tin tips appearing in varying degrees. This is a typical phenomenon of manual soldering.
LED strip lights usually use aluminum as the radiator. The larger the contact area between the radiator and the air, the better. This is conducive to heat dissipation. The whole lamp works stably, has low light attenuation and has a long life. The bulbs and ceiling spotlights should not have excessive ventilation. holes to prevent mosquitoes from crawling in during use, affecting the lighting effect or causing unnecessary damage.
The quality of the waterproof plug directly determines whether the LED hard strip light can work properly. With the expansion of my country's LED strip light market in recent years, competition among industries has become increasingly fierce. In order to save capital, some LED light manufacturers have They cut corners, such as tampering with the waterproof plug. Therefore, to choose a good LED strip light, you also need to look at the quality of the waterproof plug.
If the LED strip light shows such a serious yellowing phenomenon after one year of use, do not buy this type of product. It is because the glue used in the linear lights is too poor. There are many sold on the market under the name of waterproof PU glue. The inferior glue has poor waterproof performance and is prone to yellowing and darkening. Likewise, its price is far different from that of normal waterproof PU glue. Basically, the price difference is more than double.
Regular LED strip lights will be packed in anti-static reels, and then sealed in anti-static and moisture-proof packaging bags. In order to save costs, the knock-off version of the LED strip light does not use anti-static and moisture-proof packaging bags. If you look carefully at the reel, you can see that there are traces and scratches on the surface left when the label is pasted.
