1, the brightness of LED Solar Street Lightis different, the price is different. The LED used for LED lamps should conform to the laser class I standard.
2, LED solar street lamp antistatic ability, strong antistatic ability LED, long life, and therefore the price is high. Usually, LED with an electrostatic strength greater than 700V can be used for LED lighting.
3. LED with the same wavelength of LED solar street lamp, the same color, if the color is required, the price is high. It is difficult for manufacturers without LED spectrometers to produce pure color products.
4. Lead Solar Street Lighting leakage current LED is a unidirectional light emitter, if there is a reverse current, it is called leakage, leakage current LED, short life, low price.
5, LED solar street lighting angle uses different LED, its luminous angle is different. Special luminous angle, higher price. Such as the full diffusing angle, the price is higher.
6, the key to the life of LED solar streetlights is life expectancy and life expectancy is determined by light decay. Light decay, long life, long life and high price.
7, LED solar street lamp chip LED's luminous body is chip, different chip, the price difference is very big. Chips in Japan and the United States are more expensive, and the prices of chips in Taiwan and China are lower than those in Japan and the United States.
8. The size of LED solar street lamp chip is indicated by the side length, and the quality of large chip LED is better than that of small chip. The price is directly proportional to the chip size.
