Road lighting is an important part of urban lighting. Traditional street lamps are often used. The high-pressure sodium lamp emits light at 360 degrees, which causes 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 national economy, the contradiction between energy supply and demand in China has become increasingly prominent, and the power supply is seriously insufficient. Energy saving is an urgent problem to be solved. Therefore, it is of great significance to develop new LED street lamps with high efficiency, energy saving, long life, high color rendering index and environmental protection for urban lighting energy saving.
Road lighting is closely related to people's production and life. With the acceleration of urbanization in China, LED street lamps have gradually entered people's field of vision with the advantages of directional lighting, low power consumption, good driving characteristics, fast response, high earthquake resistance, long life and environmental protection, and become the new generation of energy-saving light sources with the most advantages of replacing traditional light sources in the world. Therefore, LED street lamps will become the best choice for energy-saving transformation of road lighting.
Different from traditional street lamps, LED light source adopts low-voltage DC power supply and high-efficiency white light synthesized by GaN-based power blue LED and yellow, which has the unique advantages of high efficiency, safety, energy saving, environmental protection, long service life, fast response and high color rendering index, and can be widely used in roads. The outer cover can be made of high temperature 135 degrees and low temperature -45 degrees.
By the end of 2007, the total number of street lamps for urban road lighting had reached 6,543.8+03.95 million, with an annual growth rate of 654.38+00% to 20%. Therefore, the urban road lighting energy-saving market can not be ignored.
At the the State Council executive meeting in 2009, semiconductor lighting was included in the measures to expand domestic demand. On April 28th, 2009, the Ministry of Science and Technology approved 2 1 city as the pilot application of semiconductor lighting in "Ten Cities with Ten Lights". Through the demonstration project of "Ten Cities with Ten Lights", the application of LED lighting technology will be promoted to achieve the goal of economic growth.
