q: how to design and determine the efficiency of led street light? A: L light pole factory led street lamp power efficiency refers to the input power and the ratio of the led street lamp power work power. This parameter is very important. Efficiency value is smaller, the lower the efficiency, which indicates that a large part of the input power is converted into heat to send out. Led street lamp power all the electronic components in life will shorten with the increase of temperature, after more than 80 degrees Celsius, the life will be cut in half every five degrees. Led street lights, energy efficiency is the most basic factor of led street lamp life.
