LED lamp beads play a vital role in the LED display system. However, many people do not know much about the prices of LED beads. What is the reason why the prices of LED lamp beads are so different? IAM USED LED Wall will guide you the following introduction, let’s take a look at the price of LED lamp beads and its influencing factors!
Factors affecting the price of LED lamp beads of LED displays
LED lamp bead chip
Chips include China, Taiwanese chips and imported chips (including American chips, Japanese chips, German chips, etc.). Different chips have huge price differences. Currently, the most expensive American chips are followed by Japanese chips and German chips. The lowest-priced Taiwanese chips have slightly poorer heat dissipation performance. What kind of chip is used specifically? What kind of effect is to be achieved? You should know it before buying.
LED size
Different size LEDs have different prices. For example, the prices of SMD0603 LED and SMD1210 or SMD3528 LED are quite different; and the prices of LEDs with specifications of SMD1210 and SMD5050 are even different. When buying LED display, don’t just focus on the price. The following aspects should be comprehensively assessed in order to purchase high-quality LED display.
LED packaging
Divided into resin encapsulation and silicone encapsulation. Resin encapsulation is cheaper. Everything else is the same. Silicone encapsulation has good heat dissipation performance, so the price is slightly more expensive than resin encapsulation.
LED color consistency
At present, there are many LED packaging manufacturers in China like Nationstar LED and Kinglight LED. There are thousands of large and small companies in total, and of course there are strong and weak ones. There are many small LED packaging manufacturers that do not have spectroscopic and color separation machines, so they either do not do spectroscopic and color separation, or they send out the products outsourced, which makes it difficult to guarantee quality. LEDs that have not been separated by light and color have poor color consistency, and the effect after being installed on LED lamp beads and lit is not that good. Of course, the price difference is relatively large.
FPC material
FPC is divided into two types: rolled copper and coated copper. Copper-clad laminates are cheaper, and rolled copper is more expensive. The pads of copper-clad boards tend to fall off when bent, but rolled copper does not. The specific material used for FPC depends on the promoter’s decision based on the use environment.
Has the FPC passed environmental certification or UL certification? Does the LED have any patents? None are cheap. Certified and patented ones are more expensive.
LED welding effect
The assembly of LED lamp beads is divided into two types: manual welding and machine welding.
Manual soldering is to use a soldering iron and use the most primitive method to solder. The products produced in this way have an ugly appearance. In addition. the electrostatic protection measures are not good, and many LED chips are broken down, resulting in a slight brightness or no brightness when the power is turned on.
Machine welding uses reflow soldering, but machine welding is different. Not only does the soldered product look beautiful (solder joints are of consistent size, smooth, no flux residue, and the LED package is intact), but the chip will not be burned by static electricity. At the same time, the LED position and direction are more beautiful.
LED color
Red and green colors are more difficult to match and perform spectroscopic color separation, so the price is higher than other colors; red, yellow, blue and other colors are easier to spectroscopically separate and have better consistency, so the price is slightly cheaper.
LED brightness
Different brightness LEDs have different prices. The price difference between ordinary brightness and high-brightness LEDs is quite large. Therefore, when purchasing LED display, you must clearly know what kind of brightness you need, so that you can accurately position your product.
