1. LED brightness (MCD) is different, and the price is different. The LED used for LED lamps shall conform to the Class I standard of laser radiation level.
2. The LED with strong anti-static ability has a long service life, so its price is high. Generally, an LED with an antistatic voltage greater than 700V can be used for LED lighting.
3. The LED with the same wavelength has the same color. If the color is required to be consistent, the price is high. It is difficult for manufacturers without LED spectrophotometers to produce pure-color products.
4. Leakage current LED is a unidirectional conductive luminous body. If there is a reverse current, it is called a leakage current. LED with large leakage current has a short life and low price.
5. The luminous angle is different for LEDs with different purposes. Special luminous angle, high price. Such as a full diffusion angle, the price is higher.
6. The key to a different quality of life is life, which is determined by light decay. Small light attenuation, long life, long life, and high price.
7. The luminous body of chip LED is a chip, and the price varies greatly with different chips. Chips from Japan and the United States are more expensive. Generally, chips from Taiwan and China are cheaper than those from Japan and the United States (CREE).
8. Chip Size The size of a chip is expressed in terms of its side length, and the quality of a large chip LED is better than that of a small chip LED. The price is proportional to the chip size.
9. The colloid of ordinary LED is generally epoxy resin. LED with anti-ultraviolet and fire retardant is expensive. High-quality outdoor LED lighting should be anti-ultraviolet and fireproof. Each product has different designs, which 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 shall comply with relevant international and national standards.
