QQ Phone East China Zhou Wenbiao //.ohzmdj.com/I heard that *the price of LED display has been reduced again, Mr. Zhang is going to buy one to enhance the overall image of his fruit shop, but as soon as he enters the LED electronic market various products There is a dazzling array of things, and I don’t know how to do it, so I can only get a preliminary understanding through a simple introduction to the shopping guide, and I really feel that I have no choice. * Later, he came to a counter where he was doing activities. Since the price was much lower than other counters, he made up his mind to buy one. But it didn't take long for this screen to have many problems such as dead lights, and he had to pay for it, which undoubtedly made him very annoyed.
After reading this short story, do you feel the same, blindly pursuing low prices, but neglecting the cost-effectiveness of the products, really shouldn't, so facing the market malicious low price trap, you need to be more vigilant!
So why is the price gap between the same LED display screens so big? We know that the most important factor affecting the cost of LED display screens is the components. Among the components, the highest proportion of the cost is the lamp. Let's use the powerful Jucai S goddess product to make an analysis. The lamp is the most used component of Goddess S, with as many as tens of thousands per square meter; the cost of lamps in Goddess S products accounts for as high as %-%. Therefore, the quality of the tube will directly affect the price of Goddess S.
So the question is, why does Goddess S have to use high-quality lamps? What is so good about the so-called high-grade lamps? How to distinguish it? Next, let's take a look at the excellent domestic lamp suppliers. Xingguang’s professional analysis.
**Trick: Look at the bracket
At present, the mainstream metal brackets for lamp tubes in the market are copper-plated silver and iron-plated silver. Although the two metals are only one word difference, they are very large in terms of electrical conductivity, thermal conductivity, corrosion resistance and price. The difference.
During the use of outdoor LED displays, they often face harsh environments such as rainy and humid, sunny days, etc. This requires devices to have good performance to withstand external losses. Strong corrosion resistance, good electrical and thermal conductivity can make the device have the advantages of longer life, better heat dissipation, and less light attenuation. Through comparative tests, we can conclude that the performance of the copper stent is far superior to that of the iron stent. However, the price of copper stents is twice or even higher than that of iron stents. For this reason, many manufacturers disregard the quality of the devices, only pursue low cost and high return, and choose iron stents as raw materials. Therefore, so many 'low-cost devices' appear on the market.
**Trick: Identify bonding wires
The LED lamp needs to connect the chip and the pin as a current channel through the connecting wire, and the bonding wire serves as the connecting wire. Like the bracket alloy, the bonding wire is also an important part of the device, and its quality directly affects the quality of the lamp. Manufacturers* commonly used bonding wires include copper wire, alloy wire and pure gold wire. Let's compare the differences between the bonding wires of the three metals.
Pure gold wire is more inert than copper wire and alloy wire. It has more advantages in terms of oxidation resistance, back pressure resistance and manufacturing process. It is the best choice for LED device materials. However, because high-purity gold resources are scarce and expensive, the price of gold wire is twice that of copper wire, and the price of alloy wire is between gold and copper wires. Therefore, if you want to get better quality LED devices, the price is certainly not that cheap.
So if you want to pursue a high-quality LED display, don't blindly pursue low prices, because the cost price is there, and no one can escape! The S Goddess series surface mount products are equipped with National Star Optoelectronics copper Bracket + pure gold wire tube, the quality of this kind of tube can be described as the best. It has been used for military parade. It adopts brick and three-proof design. It can pass high-strength environmental tests such as MSL, cycles and severe cold and heat shocks. It is resistant to back pressure and salt and alkali. It has strong corrosion ability and has been put into the market for years, but it has passed strict market inspection.
After sharing the dry goods, you are as witty as you. I believe that when you encounter the low price trap of LED display again in the future, you will make a wise judgment.
