How to choose LED street light?
As a large product, purchase before buying become everyone's focus. As an LED engineer, I talk to you today to pick LED street lights need to pay attention to things. Select LED lights, mainly from the specifications, LED tube life, anti-static parameters of these to choose, color, leakage is also very important.
LED brightness (MCD) different, the price is different. LED lamps for LED should meet the laser class Ⅰ standard.
Anti-static ability Anti-static ability of the LED, long life, and thus high prices. Generally more than 700V antistatic LED can be used for LED lighting
Wavelength consistent LED, the same color, such as the requirements of the same color, the price is high. Manufacturers without an LED spectrophotometer can hardly produce pure colors.
Leakage current LED is a one-way conductive street lights, if there is reverse current, then known as leakage, leakage current LED, short life expectancy, low price
LED angle of use Different LED lighting angle is not the same. Special lighting angle, the price is higher. If full diffuse angle, the price is higher.
The company is located in:
Life The key to different qualities is life, life is determined by the light fades. Low light failure, long life, long life, high prices.
Chip LED luminous body for the chip, different chips, the price is very different. Japan, the United States more expensive chips, the general Taiwan and domestic chip prices lower than Japan, the United States (CREE).

Chip size The size of the chip to the side that the quality of large chip LED chip is better than small. The price is proportional to the size of the chip.
