LED light source is already a very familiar product in the LED industry, but many people don’t know much about the price of LED SMD lamp beads. What makes the price of LED SMD lamp beads so different? Take a look below You can clearly understand the introduction, let’s take a look at the factors that affect the price of LED light sources.
1. LED light source size: LED light sources of different specifications and sizes have different prices.
2. Chips used in LED light sources: Chips include domestic and Taiwanese chips and imported chips. The prices are very different for different chips. At present, the most expensive American chips are followed by Japanese chips and German chips. The lowest-priced Taiwanese chips have poor heat dissipation performance.
3. LED light source packaging: resin packaging and silicone packaging. The price of 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.
4. The color consistency of LED light source: At present, there are many packaging factories in China, and there are thousands of large and small. Of course, there are strengths and weaknesses. The color consistency of the LED chip beads that have not undergone color separation is poor, and the effect after lighting is not so good, of course, the price difference is relatively large.
5. LED light source welding effect: The assembly of LED chip lamp beads is divided into manual welding and machine welding. Manual soldering is to use a soldering iron, using the most primitive method for soldering. Machine soldering uses reflow soldering, but machine soldering is different. This can be seen directly from the appearance.
6. FPC material: FPC is divided into two types: rolled copper and copper-clad. Copper-clad boards are cheaper, and rolled copper is more expensive. The pads of the copper-clad board are easy to fall off when bent, but the rolled copper will not. The specific FPC material to be used depends on the seller's decision according to the environment in which it is used.
7. Does FPC have passed environmental certification or UL certification? Is there a patent for LED? There is no low price. Certified and patented ones are more expensive.
8. LED light source brightness: LED light sources with different brightness have different prices. The price difference between ordinary brightness and high brightness LED light source is quite different.
9. LED light source color: different colors. The price is different. Red and green are more difficult to match and separate, so the price is higher than other colors; red, yellow, blue and other colors are easier to separate and have better consistency, so the price is slightly cheaper. Special colors such as purple and brown are the most expensive due to color matching reasons.
