Abstract: There are still some illegal people in the LED lighting lighting market, deceive suppliers, defraud suppliers of materials to produce finished products, and sell finished products at unusually low prices in exchange for cash. To avoid being cheated, you need to understand the factors that affect the price difference of LED lamps.
Let's take a look at what factors contribute to LED lamp price differences:
1, brightness
LED brightness is different, the price is different.
2, anti-static ability
The LED with strong anti-static ability has a long life and is therefore expensive. Usually the LED with antistatic capacity greater than 700V can be used for LED lighting.
3, wavelength
Wavelength-consistent LEDs have the same color. If the color is the same, the price is high. Manufacturers without LED spectrophotometers have difficulty producing products with pure colors.
4, leakage current
LED is a one-way conductive light, if there is a reverse current, it is called leakage, LED leakage current, short life, low price.
5, light angle
Different uses of LED have different lighting angles. Special light angle, higher prices. Such as full diffusion angle, the price is higher.
6, life
The key to different qualities is life, and life is determined by light decay. Low light decay, long life, long life, and high price.
7, LED chip
LED's luminous body is the chip, different chip, the price is very different. Japan and the United States have more expensive chips, and LED chips from Taiwanese and Chinese manufacturers are lower than Japan and the United States.
8, chip size
The size of the chip is represented by the length of the side, and the quality of the large chip LED is better than that of the small chip. The price is directly proportional to the size of the chip.
9, colloid
Ordinary LED's colloid is generally epoxy resin, plus anti-UV and fire retardant LED's more expensive, high-quality outdoor LED lighting should be UV and fire.
There are still some illegal people in the LED lighting lighting market, deceive suppliers, fraudulently take supplier materials to produce finished products, and sell finished products at unusually low prices in exchange for cash. There are also a few LED lighting manufacturers who deceive dealers and users with unrealistic promises, and then shirk their responsibility by constantly changing the trade name or responsible person's tactics.
