LED lens strips are widely used in light boxes, but when purchasing, face A wide variety of LED lens strips, we are also at a loss when purchasing We need to pay attention to these tricks.

The first trick, look at the glue: some LED lens strips will be damaged after 1 year The serious yellowing of the glue is because the glue material is too poor. There are many inferior glues sold in the name of waterproof PU glue on the market. They have poor waterproof performance and are prone to yellowing and darkening. The same is the same as normal waterproof PU glue. The prices are very different, basically the price difference is more than double.

The second trick, look at aluminum: ultra-thin aluminum is easy to deform, in LED lens strip In the selection of aluminum materials for /a>, regular manufacturers will first consider whether the heat dissipation performance is good or not. Do you think that the thicker the aluminum material, the better? In fact, it is not. The makeup you put on, the thicker the foundation, the better it looks? Certainly not. If you want to make the aluminum material not easily deformed and have good heat dissipation, you must choose a moderate thickness. It cannot be said that the thicker the aluminum material is, the better. In addition, if LED lens light bar The thinner the aluminum material, the better the heat dissipation? NO! The thinner the aluminum, the worse the heat dissipation, and it is easy to be squeezed and deformed during installation, so it is not necessary to cut corners! In addition, it is a question of cost performance. If you want high cost performance, manufacturers must control the materials used quite well.

The third trick is to look at the lamp bead components: in the industry, there are only a few well-known packaging manufacturers, such as Cree - Purui - Nichia - Taiwan Jingyuan, etc., but you can tell whether it is you or not Did you get the brand chip? There are some unscrupulous LED lens light bar manufacturers. Their quotations advertise how good the raw materials are, and they sell chips for a few cents as big brand chips, but the price law has always existed, how can it be cheap to buy good ones? goods? Customers are also deceiving themselves, being deceived willingly, and being drunk. There are some domestic lamp bead brands that have been tested and improved for many years, and their craftsmanship and technology are also very skilled and stable. According to your project cost, you can also choose some domestic better brands.

The fourth trick is to look at the selection of circuit boards: is aluminum substrate better than fiberglass? Really good quality LED lens light bar, most of them choose aluminum substrate as light source for the circuit board. Has fiberglass board always been labeled as inferior? This is not true. I used to think that glass fiber board products are not high-quality products. Later, after the technician's explanation, I also understood that glass fiber boards are also good or bad, and even better than the quality of aluminum substrates. As long as they perform stably, Whether it is an aluminum substrate or a glass fiber board, they are all good circuit boards.

The fifth trick is to look at the waterproof plug: the LED market is really big. Every year, customers will ask: "Is there any new price this year?" There are also some manufacturers who have lowered their profits to maintain their original customers. There are also cheap waterproof plugs, but relatively speaking, they have poor electrical conductivity and poor waterproof performance. Yes, although its price is high, the overall stability can reach 99% waterproof, and the 1% may be not plugged tightly.
