The method of lighting up the space with lights is derived from the concept of "Light washing" pioneered by two masters Richard Kelly and Philip Johnson. It is very popular in current home decoration, so how to distinguish the quality of LED lights Well, why is the price difference between different LED strips so big?

　　1. The number of LED lamp beads

　　Because the number of lamp beads is different, the brightness of the lamp strip is also different. Generally speaking, the more LED lamp beads in the same unit, the higher the brightness of the lamp strip. For example, two one-meter-long light strips, one of which is 126 beads and the other is 140 beads, the latter will be brighter than the former.

　　But besides the lamp beads, the wattage determines the brightness of the lamp strip. If the number of LED lamp beads in a unit is the same, the lamp strip with higher wattage will be brighter than the lower wattage.

　　Second, the material of the LED light bar

　　In terms of materials, there are two types of LED light strips, LED hard light strips and LED soft light strips. The soft light strips are made of flexible materials. The hard light bar is an assembled circuit board made of PCB hard board. The hard light bar and the soft light strip have their own advantages and disadvantages. The advantage of the LED hard light bar is that it is easier to fix, its processing and installation are more convenient, and the disadvantage is hard. The material cannot be bent at will.

　　The light bar can be assembled by attaching LEDs, or by inserting LEDs for assembly.

　　LED flexible light strips often use FPC to assemble circuit boards, and then use SMD LEDs for assembly. Its advantage is that the product is very thin, does not occupy extra space, and is easy to bend. It is very convenient to make various assembly shapes, and the price is slightly lower. Light Bar.

　　Third, the chip

　　LED chips are the factors that determine the core quality of LEDs. There are many brands of LED chips, including European and American brands, Taiwanese brands, and domestic brands. Generally speaking, the quality of European and American brands is higher than that of domestic brands, but their prices are domestically produced4 , 5 times, it is recommended to buy light strips with domestic chips. It is more economical and cost-effective. The main gap between imported chips and domestic chips is in light efficiency, but this gap is not very large, such as Xiamen San’an’s chip light efficiency. 120 lumens/watt, imported CREE chips with the same variable can make 130 lumens/watt. There is no need to spend extra high price to buy a little brightness advantage. As far as domestic manufacturers are concerned, as long as they are certified domestically, there is no problem. Now domestic chips are doing better and better, and they are becoming more and more popular in the international market. .

　　Four, waterproof level

　　LED lamps generally require protection levels. The higher the protection level, the more expensive the price. Generally speaking, IP20 is suitable for indoor dry environments, IP65 is suitable for indoor humid environments, IP66 is suitable for outdoor environments, and IP68 is suitable for underwater environments. You can choose according to your own use environment.
