How Is the Price of LED Lamp Beads Fixed? What Are the Effects of Lamp Beads

LED lamp beads are already a very familiar product in the LED industry, but many people do nt know much about the price of LED lamp beads. What is the reason why LED lamp beads are very different? Everyone introduces factors affecting the price of LED lamp beads. 1. LED lamp bead brightness. The price of LEDs with different brightness is different. The price difference between ordinary brightness and high bright LED is very different. 2. The chip used by LED lamp beads. The chips include domestic and Zhuhai chips and imported chips (including American chips, Japanese chips, German chips, etc.). The chip is different, the price difference is very different. Currently more expensive American chips, followed by Japanese chips and German chips. The lower -priced Zhuhai chip has a slightly worse heat dissipation performance. 3. The effect of LED size on price. Different specifications of LEDs are different. For example, the price of 0603 LED lamp beads and 3528LED lamp beads is large; and the price of LEDs of 3528 and 5050 is different. Don't just pay attention to the price when buying LED lamp beads. Comprehensive assessment should. 4. LED installation. Divide resin packaging and silicone packaging. The price of resin packaging is cheaper. Others are the same. The cooling performance of silicone packaging is good, so the price is slightly more expensive than resin packaging. 5. LED lamp bead welding effect. The assembly and breakup of LED lamp beads, handmade welding and machine welding. Manual welding is to use the soldering iron and use the most primitive method for welding. The product that enters this operation is ugly (the welding joints are inconsistent with the size of the Fuzhou LED electronic display). The second is that the static maintenance measures are not good. Machine welding is welded with reflux welding, and machine welding is different. Not only the welding product is beautiful (the size of the welding joint, the smooth welding joints, the residual welding residue, the LED packaging is intact), and there will be no phenomenon of chip being burned by electrostatic and burning. At the same time, the LED position and direction are more beautiful. This can be seen directly from the appearance. 6. The consistency of the color of LED lamp beads. There are currently many packaging factories in China. There are thousands of large and small plus up, of course, there are strengths of strength and weakness. There are many small packaging factories because there is no split color division machine, so it is either different from the color or color, so it is difficult to guarantee the quality. The color consistency of the LED without splitting color is poor, and the effect after lighting on the LED lamp bead is not so good, of course, the price difference is relatively large. 7. Does the FPC have undergone environmental certification and UL certification? Is there any patent for LED?. No price is low. The price of certification and patent is more expensive. 8. FPC material. FPC division pressure dependent copper and copper applied copper. It is cheaper to apply copper plate, and it is more expensive. The pad of the copper plate is easy to fall off when the bend is bent, but the crushing copper will not. What kind of material is used to make decisions based on your own environmental environment to make decisions. 9. LED lamp bead color. Different color. Different price. Red and green are difficult to split color and color matching, so the price is higher than the price of other colors; the color of red, yellow, blue and other colors is easier and consistent. Therefore, the price is slightly cheaper. Special colors such as purple and brown due to color reasons, the price is the most expensive.
