With the overwhelming market, as consumers, choosing LED still needs to be calm, scientifically analyzed, and choose the best cost-effective light source lamps. Below are the basic performance of several LEDs:
1. Brightness. The brightness of LEDs varies and their prices vary. The LED used for LED lighting fixtures should comply with the Class I standard for laser rating.
2. Antistatic ability. LED with strong anti-static ability has a long lifespan and is therefore expensive. Usually, LEDs with an anti-static voltage greater than 700V can be used for LED lighting.
3. Wavelength. LEDs with consistent wavelengths have consistent colors. If color consistency is required, the price is high. Manufacturers without LED color separators find it difficult to produce products with pure colors.
4. Leakage. Current LED is a unidirectional conductive luminous body. If there is reverse current, it is called leakage current. LED with high leakage current has a lifespan
Short lifespan, low price.
5. Glow. LEDs with different angles and purposes have different luminous angles. Special luminous angle, high price. If it has a full diffuse angle, the price is higher.
6. Lifetime. The key to different qualities is lifespan, which is determined by light decay. Low light attenuation, long lifespan, long lifespan, and high price.
7. Wafer. The luminescent body of LED is a chip, and the price varies greatly among different chips. Chips from Japan and the United States are more expensive, while chips from Taiwan and China are generally priced lower than those from Japan and the United States.
8. Chip size. The size of a chip is represented by its edge length, and the quality of a large chip LED is better than that of a small chip. The price is proportional to the size of the wafer.
