Learn these five easy to distinguish the quality of LED line lights
2024-05-28

Now the style of LED line lights is dazzling, many manufacturers recommend their own line lights made of good quality, low price, long service life, etc., there are some expensive "brand goods", in the end how do we distinguish the quality of line lights, from which points to analyze?

Analyze the quality of line lights from the basic five points

First of all, look at the glue: after 1 year, the line lamp has a serious yellowing phenomenon because the glue is too poor, there are many inferior glue on the market in the name of waterproof PU glue to sell, poor waterproof performance, easy to yellow and dark, the same with the normal waterproof PU glue price is very far apart, basically more than double the price.

The second trick, look at aluminum: ultra-thin aluminum is changeable, in the aluminum selection of line lights, regular manufacturers will first consider the heat dissipation performance is good, do you think that the thicker the aluminum, the better? In fact, it's not true. The thicker the foundation, the better you look. Certainly not, aluminum if you want to do not easy deformation, good heat dissipation, you must choose a moderate thickness, can not say that blindly want aluminum thicker the better, in addition, if the aluminum of the line lamp thinner is not the better heat dissipation? Noooo! The thinner the aluminum, the worse the heat dissipation, and the easier it is to squeeze and deform during installation, so it is not necessary to cut corners! Another is a cost-effective problem, if you want to be cost-effective, manufacturers must control the material is quite good.

The third trick, look at the lamp bead components: In the industry, the packaging manufacturers are well-known only a few, but you can tell whether this is not the brand chip you got? There are some unconscionable line lamp manufacturers whose quotes advertise how good the raw materials are, holding a few cents of chips to pretend to be high-quality chips to sell, but the law of prices has always existed, how can cheap buy good goods? There are some domestic lamp bead brands after years of testing and improvement, their process and play is also quite mature and stable, according to your project cost can also choose some domestic better brands.

The fourth trick, look at the selection of circuit boards: aluminum substrate will be better than glass fiber board? Really good quality line lights, most of the use of aluminum substrate as a light source circuit board. Is fiberglass always labeled as inferior? This is not true, glass fiber board also has good or bad, and some can be better than the quality of aluminum substrate, as long as the stable play, whether aluminum substrate or glass fiber board, they are good circuit boards.

The fifth trick, look at the waterproof plug: the LED market is really large, every year, customers will consult once: "There is no new price this year", some manufacturers are forced by this pressure, will be a little less in the material, waterproof plug is also cheap, but relatively speaking, the conductivity is not good, waterproof performance is poor, easy to water leakage, although the good waterproof plug price is high, but the overall stability can reach 99% waterproof.
