1. The LED brightness (MCD) is different and the price is different. The LEDs used for LED lamps should meet the laser class I standard.
2. LED with strong antistatic ability have long life and high price. Usually LEDs with anti-static greater than 700V can be used for LED lighting.
3. LED with the same wavelength have the same color. If the color is required to be the same, the price will be high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure color.
4. Leakage current LED is a unidirectional conductive luminous body. If there is a reverse current, it is called leakage current. LEDs with large leakage current have short life and low price.
5. LED with different lighting angles have different lighting angles. Special lighting angle, higher price. Such as the full diffusion angle, the price is higher.
6. Lifespan The key to different qualities is lifespan, which is determined by light decay. Low light decay, long life, long life and high price.
7. The luminous body of the chip LED is a chip, and the price of different chips varies greatly. Chips in Japan and the United States are more expensive. Generally, the prices of chips in Taiwan and China are lower than those in Japan and the United States (CREE).
8. Chip size The size of the chip is represented 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 wafer size.
9. Colloid The colloid of ordinary LED is generally epoxy resin. The LED with anti-ultraviolet and fire-retardant agent is more expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fireproof. Each product will have a different design, and different designs are suitable for different purposes. The reliability design of LED lighting includes: electrical safety, fire safety, applicable environmental safety, mechanical safety, health and safety, safe use time and other factors. From the perspective of electrical safety, it should comply with relevant international and national standards.
