Road lighting is an important part of urban lighting. Traditional street lamps often use high-pressure sodium lamps that emit light in 360 degrees. The disadvantage of large light loss has caused a huge waste of energy. At present, the global environment is deteriorating day by day, and all countries are developing clean energy. With the rapid growth of the national economy, the contradiction between energy supply and demand in our country has become increasingly prominent, and there is a serious shortage of power supply. Energy conservation is an urgent problem to be solved. Therefore, the development of new types of LED street lamps that are highly efficient, energy-saving, long-lasting, have a high color rendering index and are environmentally friendly is of great significance for energy conservation in urban lighting.
Road lighting is closely related to people's production and life. With the acceleration of urbanization in China, LED street lamps have gradually come into people's view due to their advantages such as directional light emission, low power consumption, good driving characteristics, fast response speed, high shock resistance, long service life, and environmental friendliness. They have become the new generation of energy-saving light sources with the most advantages to replace traditional light sources in the world. Therefore, LED street lamps will become the best choice for energy-saving renovations of road lighting.
