The factors affecting the price of LED light source

There is a big difference in the price of LED chip light beads, then what are the factors affecting the price of LED light source?

1. LED light source size: the price of LED light sources of different sizes is different.

2. Chips used for LED light source: domestic and Taiwan chips and imported chips. The price varies greatly with different chips. At present, the most expensive American chips are followed by Japanese chips and German chips. The lowest price Taiwanese chips have slightly poor heat dissipation performance.

3. LED light source packaging: resin packaging and silicone packaging. The price of resin packaging is cheaper. Everything else is the same. The heat dissipation performance of silicone packaging is good, so the price is slightly more expensive than that of resin packaging.

4. Color consistency of LED light source: at present, there are many packaging plants in China, including thousands of large and small ones. Of course, there are strengths and weaknesses. The color consistency of LED patch beads without light and color separation is poor, and the effect after lighting is not so good. Of course, the price difference is relatively large.

5. Welding effect of LED light source: there are two kinds of LED chip lamp bead assembly: manual welding and machine welding. Manual welding is to use soldering iron and use the most original method for welding. Machine welding is reflow welding, which is different from machine welding. This can be seen directly from the appearance.

6. FPC material: FPC is divided into calendered copper and copper coating. Copper clad plate is cheaper and calendered copper is more expensive. The pad of copper clad plate is easy to fall off during bending, while the calendered copper will not. The specific material of FPC depends on the salesperson's decision according to the use environment.

7. Has FPC passed environmental protection certification and UL certification? Whether the LED has patent, etc. No, the price is low. Certified and patented products are more expensive.

8. LED light source brightness: the price of LED light sources with different brightness is different. The price of ordinary brightness and bright LED light source is quite different.

9. LED light source color: different colors. The price is different. The price of red and green is higher than that of other colors due to the difficulty of color matching and light and color separation; The light and color separation of red, yellow and blue is relatively easy and consistent, so the price is slightly cheaper. Special colors such as purple and Brown are the most expensive due to color matching.
