Nine major determinants of the price of led lights
LED size: LED strips of different specifications and sizes have different prices. For example, the price of 0603 LED and 1210 or 3528 led strips are quite different; while the price of 1210 and 5050 led strips differs by another step. Don't just pay attention to the price when buying LED strips. It should be comprehensively assessed from the following aspects in order to purchase high-quality and inexpensive led light strips.
Chips used in led strips: chips include domestic and Taiwanese chips and imported chips (including American chips, Japanese chips, German chips, etc.). The price of chips varies greatly.
LED lamp strip packaging: divided into resin packaging and silicone packaging. The price of resin-encapsulated led strip is cheaper. Everything else is the same. The silicone package has good heat dissipation performance, so the price is slightly more expensive than the resin package.
The color consistency of the led strip: There are many packaging factories in China. There are thousands of big and small companies, and of course there are strengths and weaknesses. There are many small packaging factories that do not have spectroscopy and color separation machines, so they either do not perform spectroscopy or are outsourced, so it is difficult to guarantee the quality. The color consistency of LEDs that have not undergone color separation is poor, and the effect after lighting on the LED strip is not so good. Of course, the price difference of the LED strip is relatively large.
LED light strip welding effect: LED light strip assembly is divided into manual welding and machine welding. Manual soldering is to use a soldering iron, using the most primitive method for soldering. The products with this kind of operation are ugly in appearance (the solder joint size is inconsistent, Fuzhou LED electronic display screen), and the electrostatic maintenance measures are not good. Many LED chips are broken down, causing the phenomenon of dim light or no light when power is on. Machine soldering uses reflow soldering, but machine soldering is different. Not only the appearance of the soldered product is beautiful (the solder joints are the same size, the solder joints are smooth, there is no flux residue, and the LED package is intact), but the chip will not be burned by static electricity. At the same time, the position and direction of the led strip are more beautiful. This can be seen directly from the appearance.
LED lamp strip FPC material: FPC is divided into two types: rolled copper and coated copper. 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 use environment.
Is the LED lamp belt FPC certified for environmental protection and UL certification? Is there a patent for LED? The LED strips that do not have low prices. Certified and patented ones are more expensive.
LED strip brightness: LED strips with different brightness have different prices. The price difference between ordinary brightness and high-brightness led strip is quite different. Therefore, you must clearly know what kind of brightness you need when buying, so that you can accurately locate your product.
LED strip color: different colors. The price of led lights 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 of led strips is slightly cheaper. Special colors such as purple and brown are the most expensive due to color matching.
