LED strip price
LED strip is very popular at present. It is not only rich in color, but also energy-saving and environmentally friendly, and is widely used. It can be used to replace the traditional lamp. The price in LED strip is not very expensive at present. If it is monochrome, one meter is between a few yuan and a dozen yuan. If it is color RGB, it will be more expensive. The prices of different specifications and varieties are different. Specifically, the price ranges from around 5 yuan to tens of yuan. It is recommended not to use 220V high-voltage optical tape, which will generate a lot of heat when starting. Life expectancy will be relatively short. Low-voltage lamp strip has long service life, energy saving and environmental protection, and its safety factor is higher than that of high-voltage lamp strip. It is best to use 12v LED soft light strip, waterproof bare board light strip or waterproof glue drip light strip in the living room. Select a specific brightness according to the optical effect. You can choose a meter of 5050,60 lights or a meter of 5050,30 lights with higher brightness. Low brightness can choose 3528, 60 meters first class. For optical effects, you can choose monochrome, color or happy lanterns.
Nine factors that determine the price of LED strip.
1.LED size
Different sizes of LEDs have different prices. For example, the prices of 0603LED and 12 10, that is, 3528LED are quite different; The price difference between 12 10 and 5050 LED specifications has reached a new level.
Chip used in 2.2. LED light bar
There are domestic and Taiwan Province chips, as well as imported chips (including American chips, Japanese chips, German chips, etc. ). Different chips have different prices. At present, American chips are the most expensive, followed by Japanese chips and German chips, while Taiwan Province chips with the lowest price have a slightly poor heat dissipation performance. What chip is used specifically? What kind of effect should it achieve? Know clearly before buying.
3.LED package
It is divided into resin encapsulation and silica gel encapsulation. The price of resin packaging is cheaper. Everything else is the same. Silica gel packaging has good heat dissipation performance, so the price is a little more expensive than resin packaging.
4.LED color consistency
At present, there are many packaging factories in China. Large and small add up to thousands, of course, there are differences in strength. There are many small packaging factories that don't have color separators, or they don't separate colors, or they can't be distributed, so the quality is difficult to guarantee. The color consistency of leds without beam splitting is poor, and the effect of installing them on LED strips is not so good. Of course, the price difference is relatively large.
5.LED welding effect
LED strip's assembly is divided into manual welding and machine welding. Manual welding is to use a soldering iron and use the most primitive method to weld. The appearance of the products in this operation mode is ugly (the solder joints are different in size), and the electrostatic maintenance measures are not good, and many LED chips are broken down, which leads to the phenomenon that they are slightly bright or not bright after power-on. Machine welding is soldering with reflow soldering, but machine welding is different. Not only is the product beautiful after welding (the solder joint size is uniform, the solder joint is 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 LED are beautiful. This can be seen directly from the appearance.
6.FPC materials
FPC can be divided into calendered copper and coated copper. Copper plating is cheaper, and calendered copper is more expensive. Copper-plated pads are easy to fall off when bent, but calendered copper is not. What kind of FPC material to use depends on the promoter's own decision according to the use environment.
7. There are seven. FPC has passed the environmental protection certification and UL certification? Is there a patent for LED?
Without the above certification and patents, the price is low, and those with certification and patents are more expensive.
8.LED brightness
The price of LEDs with different brightness is different. The price gap between ordinary brightness and high-brightness LED is still quite large. Therefore, when buying, you must clearly know what kind of brightness you need, so that you can accurately locate your products.
9.LED color
Different colors. The price is different. Red and green are more expensive than other colors because of difficulties in color matching and color separation. Red, yellow, blue and other colors are easier to separate and more consistent, so the price is slightly cheaper. Special colors such as purple and brown are the most expensive because of color matching.
