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 protection. The key to different quality of lifespan is lifespan, which is determined by light decay. However, the brightness of the LED is different and the price is different. The LEDs used for LED lamps should meet the laser class I standard.

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. Antistatic ability LEDs with strong antistatic ability have long life and high price. Usually LEDs with anti-static greater than 700V can be used for LED lighting. 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.

The illuminant 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. Chip size The size of the chip is expressed in terms of side length, and the quality of LEDs with large chips is better than that of small chips. The price is proportional to the size of the chip. The light-emitting angle of LEDs with different uses is different. Special lighting angle, higher price. Such as the full diffusion angle, the price is higher. 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 color.
