The purchase of LED lights
Sep 20, 2021
1. The LED brightness (MCD) is different, and the price is different. The LED used for 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. Leakage current 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 light-emitting angles have different light-emitting angles. Special lighting angle, higher price. Such as full diffusion angle, the price is higher.
6. The key to different qualities of life span is life span, which is determined by light decay. Low light decay, long life, long life, high price.
7. Chip LED's light-emitting body 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 made in Taiwan and China are lower than those in Japan and the United States (CREE).
8. Chip size 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. Colloid The colloid of ordinary LED is generally epoxy resin. The price of LED with anti-ultraviolet and fire retardant 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 safety, safe use time and other factors. From the perspective of electrical safety, it should comply with relevant international and national standards.
