Nowadays, the styles of LED line lights are dazzling. Many manufacturers admire the quality of their own line lights, low price, long life, etc. There are also some expensive "brand goods". How do we distinguish the line lights? Good or bad, from what time to analyze, this small series of special questions collected a lot of information for everyone. Analyze the quality of the line lights from the basic five points First of all, look at the third article in the picture, this is an unused product, the same line lamp, the first paragraph: the line lamp is purchased from a small workshop and installed on the river bank to make the outline brightening, has been used One year, due to the serious yellowing, the brightness has not reached the customer's requirements, so it was dismantled. This is a model sent by a customer to us. Section 2: The line lamp is a line lamp that has been subjected to a one-year aging test in an outdoor environment, and the surface dust is wiped off. Paragraph 3: It is a line lamp that has just been put into use. You have seen the difference between these 3 lines of lights. You certainly don’t know that their appearance may be exactly the same, so how can we avoid it? Buying inferior line lights? The first trick, look at the glue: the first line of light appeared in such a serious yellowing phenomenon after 1 year because the glue material is too bad, there are many inferior glues sold in the name of waterproof PU glue on the market, waterproof performance Poor, easy to turn yellow and dark, the same as the price of normal waterproof PU glue is very different, basically the price difference more than doubled. The second measure, look at aluminum: ultra-thin aluminum is easy to change, the aluminum material of the online strip lamp is selected. The regular manufacturer will first consider the heat dissipation performance. Do you think the thicker the aluminum is, the better? The makeup you make, the thicker the foundation, the better it looks? It is definitely not. If you want to make the aluminum material difficult to deform and heat well, you must choose a moderate thickness. You can’t say that the thicker the aluminum, the better. In addition, if the aluminum of the line lamp is thinner, is it better to dissipate heat? NO! The thinner the aluminum material, the worse the heat dissipation is. The installation is easy to squeeze and deform, so it is not necessary to cut corners. Another problem is the price/performance ratio. High, the manufacturer's materials must be controlled quite well. The third measure, look at the lamp bead components: in the industry, the packaging manufacturers are also famous, so what Curry - Puri - Nichia - Taiwan Jingyuan, etc., but you can tell if this is not you Did you get the brand chip? There are some line lamp manufacturers who have buried their conscience. His quotation advertises how good the raw materials are. He holds a few cents of chips to pretend to sell big brands of chips, but the price law has always existed. How is it possible? Cheaper will buy good goods? Customers are also self-deception, willing to be deceived, Xiaobian is also drunk. There are some lamp bead brands in China that have been tested and improved over the years. Their craftsmanship and performance are also very skillful and stable. According to your engineering cost, you can also choose some domestic brands. For example, Sanan is also a good brand. The fourth measure, look at the choice of circuit board: aluminum substrate will certainly be better than glass fiber board? Indeed, good quality line lights, mostly use aluminum substrate as a light source circuit board. Isn't the fiberglass board always labeled as inferior? This is not the case. I used to think that the fiberglass board product was not a quality product. Later, after the technician explained it, I also understood that the fiberglass board is also good or bad. It can even be better than the quality of the aluminum substrate, as long as it is stable, whether it is an aluminum substrate or a fiberglass board, they are good circuit boards. The fifth measure, look at the waterproof plug: LED market is really big, every year to start, customers will consult once: "There is no new price this year", some manufacturers are forced by this pressure, will reduce the material a little, but There are also some manufacturers that have lowered their profits to maintain their original customers. Waterproof plugs are also cheaper, but they are relatively poorly conductive, and have poor waterproof performance. They are easy to enter the water and cause leakage. Basically, the four-core plug is also very square. Not bad, although its price is high, but the overall stability can reach 99% waterproof, then 1% may not be tight.
