How to choose and compare LED light sources for light boxes

1. 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.
2. LEDs with strong anti-static ability and strong anti-static ability have a long life, so the price of such advertising equipment is high. Usually LEDs with anti-static greater than 700V can be used for LED lighting.
3. The LEDs with the same wavelength and wavelength have the same color. If the same color is required, the price will be high. It is difficult for manufacturers without LED spectrophotometers to produce products with pure color.
4. 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.
5. LEDs with different lighting angles have different lighting angles. Special lighting angle, higher price. Such as the full diffusion angle, the price is higher.
6. Lifespan The key to different qualities is lifespan, which is determined by light decay. Low light decay, long life, long life and high price.
