1. The life span is different, and the key to quality is life span. Life is determined by light decay. Low light decay, long life, and high price.
2. Chip
The luminous body of the 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 made in Taiwan and China are lower than those in Japan and the United States (CREE).
3. Chip size The size of the chip is expressed by the side length, and 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.
4. 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. 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.
