How to identify the quality of LED light strips What are the factors that affect the price of LED lights
LED light strip has a series of characteristics such as obvious power saving effect, long service life, no radiation, no stroboscopic effect, no noise, soft light, wide working voltage range, etc., and its decorative effect is also particularly prominent, so it is loved by people. At present, there are many LED light strip products on the market, and the quality is uneven. If you want to choose high-quality LED light strip products, you must understand its identification skills. Today, let BENWEI LIGHT take everyone to understand how to identify LED light strips. What are the relevant knowledge about the quality and the factors that affect the price of LED lights?

How to identify the quality of LED strips:
1. Look at the solder joints:
The LED strips produced by regular LED lamp manufacturers are produced using SMT chip technology, using solder paste and reflow soldering processes.
2. Look at the quality of FPC:
FPC is divided into two types: copper-clad and rolled copper. The copper foil of the copper-clad board is protruding, and the rolled copper is closely connected with the FPC.
3. Look at cleanliness:
If the LED light strip produced by SMT process is used, the cleanliness of the surface is very good, and no impurities and stains can be seen.
4. Look at the packaging:
The regular LED lights will be packaged in an anti-static reel, and then sealed with an anti-static and moisture-proof packaging bag.
5. Look at the label:
Regular LED light packaging bags and reels will have printed labels instead of printed labels.
6. Look at the attachment:
Regular LED lights will be equipped with instructions for use and light strip specifications in the box, and they will also be equipped with LED light connectors or card holders.

The above is a brief introduction on how to identify the quality of LED light strips. I believe that after the above introduction, everyone will have a certain understanding of the quality identification techniques of LED light strips. Of course, many people always feel that when choosing home improvement LED lamps. The price difference is always great. This is because there are many factors that affect the price of LED lights. What are the factors that affect the price of LED lights? Let's take a look at the following introduction:
What are the factors that affect the price of LED lights:
1. Brightness:
The brightness of the LED is different, and the price is different.
2. Antistatic ability:
LEDs with strong antistatic ability have long lifespan and are therefore expensive. Generally, LEDs with antistatic ability greater than 700V can be used in LED lighting.
3. Luminous angle:
LEDs with different purposes have different light-emitting angles. Special light-emitting angles are more expensive, such as full diffusion angles.
4. Life:
The key to different qualities is life, life is determined by light decay, low light decay, long life, long life, and high price.
5. Wavelength:
LEDs with the same wavelength and the same color are expensive, and it is difficult for manufacturers without LED spectrophotometers to produce products with pure colors.
6. Leakage current:
LED is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage. LEDs with large leakage current have short life and low price.
7. LED chip:
The luminous body of the LED is a chip, and the price of different chips is very different. The chips in Japan and the United States are more expensive, and the prices of LED chips from Taiwan and Chinese manufacturers are lower than those in Japan and the United States.
8. Chip size:
The size of the chip is expressed by the side length. The quality of the large chip LED is better than that of the small chip, and the price is proportional to the chip size.
9. Colloid:
The colloid of ordinary LEDs is generally epoxy resin. LEDs with anti-ultraviolet and fire retardants are more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fireproof.
