The lighting price war is becoming increasingly fierce. Products with almost the same appearance, structure, and function have 2-3 times the price difference. Many users are confused and wonder where the spread will come from. Generally, LED lighting manufacturers that do not produce LED light-emitting diodes are generally not produced. It's hard to distinguish, let alone consumers. The market is so turbulent that consumers are always looking at the flowers in the fog. What are the main factors that cause such a large price gap? Consumers should identify the basis for determining the pros and cons of these products.
The key to different quality of life is life, which is determined by light decay. Low light decay, long life, long life, and high price.
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.
Chip size The size of the chip is expressed in terms of the length of the side. 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.
Colloidal General LED colloid is generally epoxy resin, plus anti-ultraviolet radiation and fire retardant LED prices are more expensive, high-quality outdoor LED lighting should be anti-ultraviolet and fire.
LED brightness is different, the price is different. The LED used for LED lamps should meet the laser class I standard.
Anti-static ability The LED with strong anti-static ability has a long life and therefore a high price. Usually the LED with antistatic capacity greater than 700V can be used for LED lighting.
Wavelength and wavelength of the same LED, the same color, such as the requirements of the same color, the price is high. Manufacturers without LED spectrophotometers have difficulty producing products with pure colors.
LED is a one-way conductive light, if there is a reverse current, it is called leakage, LED leakage current, short life, low price.
The different angles of light used for different light emitting angles are different. Special light angle, higher prices. Such as full diffusion angle, the price is higher.
