First of all, look at the adhesive: the serious yellowing phenomenon of the line lamp after one year is because the material of the adhesive is too poor. There are many inferior adhesives sold in the name of waterproof PU adhesives on the market, and the waterproof performance is poor. , It is easy to yellow and darken. Also, it is very different from the price of normal waterproof PU glue. Basically, the price difference is more than twice.
Second-hand, look at aluminum: ultra-thin aluminum materials are easy to deform. In the selection of aluminum materials for online lamps, regular manufacturers first consider whether the heat dissipation performance is good. Do you think the thicker the aluminum material, the better? In fact, it is not. The thicker your makeup and foundation, the more beautiful, and the thinner the aluminum of the Rhine lamp, the better the heat dissipation. NO! The thinner the aluminum material, the worse the heat dissipation, and it is easy to be pressed and deformed during installation, so it is not possible to cut corners. In addition, although there is an individual price ratio problem, in order to improve the cost performance ratio, it is necessary to control the manufacturer's materials considerably.
Third-hand, look at the lamp bead parts: in the industry, these are the famous packaging manufacturers, such as Cree-Puri-Riya-Taiwan Jingyuan, etc., but can you tell if this is not the brand chip you got? ? The conscientious line lamp manufacturer advertises how good the raw materials are in his quotation. Although the chips with some money are sold as chips from large brands, the price rule has always existed. Guests who can't get cheap and good stuff are also bullying themselves, so it's nice to be cheated and the editor is drunk. Some domestic bead brands have been tested and improved for many years, and their technology and performance are also very pure and stable. You can choose some domestic better brands according to your project price. For example, Sanan is also a good brand.
The fourth technology, from the point of view of the selection of circuit boards, aluminum substrates must be better than glass plates. Indeed, high-quality circuit lights mostly use aluminum substrates as circuit boards for light sources. this is not. In the past, I also thought that the products of glass plates are not good products, but after the explanation of the technicians, there are good and bad glass plates. If the quality is better than that of the aluminum substrates, and the performance is stable, the aluminum substrates are good, and the glass plates are also good. , these are good circuit boards.
The fifth step, look at the waterproof plug: The LED market is really big. Every year, customers will ask: "Is there any new price this year?" Basically, the four-core plug in a square shape is also very good, but although the price is high, the overall Stability is still 99% waterproof, 1% of which may not be plugged in.
