1. The brightness of the high-brightness LED is different, and the price is different. The LED used in the LED lamps should meet the laser class I standard.
2. The LED with strong antistatic ability has long life and high price. Generally, LEDs with anti-static voltage greater than 700V can be used for LED Lighting.
3. LEDs with the same wavelength have the same color. If the color is required to be the same, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure colors.
4. LED is a unidirectional conductive light-emitting body. If there is a reverse current, it is called leakage. LEDs with large leakage current have short life and low price.
5. LEDs with different purposes have different light-emitting angles. Special lighting angle, higher price. Such as full diffusion angle, the price is higher.
6. The key to quality is life, and life is determined by light decay. Low light decay, long life, long life, high price.
7. The luminous body of the LED is a chip, and the price of different chips varies greatly. Chips from Japan and Germany are more expensive. Generally, the price of chips from Taiwan and China is lower than that of Japan and the United States.
8. 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. The price is proportional to the size of the chip.
9. 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.
Each product will have a different design. Different designs are suitable for different purposes. The reliability design of LED lighting includes: electrical safety, fire safety, applicable environmental safety, mechanical safety, health safety, safe use time and other factors. From the perspective of electrical safety, it should comply with relevant international and national standards.
