LED lamp with the price of 9 major determinants LED size: Different specifications of the size of the LED price is different. For example, 0603 LED and 1210 or 3528 LED have a big difference in price; while the price of 1210 and 5050 LED is a difference. Don't just pay attention to the price when buying LED strips. Comprehensive assessment should be conducted from the following aspects in order to purchase inexpensive LED light strips.
LED chips used in the chip: domestic and Taiwan chips and imported chips (including American chips, Japanese chips, German chips, etc.). Different chips, the price is very different. At present, the most expensive US chips, followed by Japanese chips and German chips, are the lowest-priced Taiwanese chips, and their heat dissipation performance is slightly inferior. What chip is used specifically? What kind of effect must I achieve? Be aware before buying.
LED package: sub resin package and silicone package. Resin package prices are cheaper. Everything else is the same. The thermal performance of the silicone package is good, so the price is slightly higher than the resin package.
LED color consistency: At present, there are many packaging factories in China. There are also thousands of large and small additions. Of course, there are strengths and weaknesses. There are many small packaging factories that have no spectrophotometric separation machine, so they either do not separate the light from the light, or they are outgoing, which makes it difficult to guarantee quality. The color consistency of the LED that has not been separated by light is not good, and the effect after being mounted on the LED light strip is not so good, and the price difference is also relatively large.
LED welding effect: The LED lamp assembly is divided into manual welding and machine welding. Manual welding is the use of iron, the most primitive method of welding. The first product of this operation mode is the appearance of ugly (inconsistent solder spot size Fuzhou LED electronic display) Second, static maintenance measures are not good, many LED chips are broken down, resulting in the phenomenon of light or not bright when powered. Machine welding uses reflow soldering. Machine welding is not the same. Not only the welded product has a beautiful appearance (uniform solder joint size, smooth solder joints, no flux residue, intact LED package), and there is no phenomenon that the chip is destroyed by static electricity. At the same time, the LED's position and direction are more beautiful. This can be seen directly from the appearance.
FPC material: FPC is divided into copper and copper. Copper plates are cheaper and rolled copper is more expensive. The copper pad's pad easily falls off when it is bent, and the rolled copper does not. The specific FPC used depends on the salesperson's decision to use the environment.
Does FPC have environmental certification or UL certification? LED has no patents. There is no cheap price. There are certified and patented prices that are more expensive.
LED brightness: different brightness LED prices are different. The difference between ordinary brightness and highlighted LED prices is very different. Therefore, when buying, be sure to know what kind of brightness you need, so that you can accurately position your product.
LED color: different colors. The price is not the same. Red and green are more difficult to match due to color separation and separation, so the price is higher than that of other colors. Red, yellow, and blue colors are easier to separate, and the consistency is better, so the price is a little cheaper. Special colors such as purple, brown, etc. are the most expensive because of color matching.
