Abstract: According to the test results of LED luminaires for road and street lighting of twice bidding for expressway of Anhui province, this article analyzes the status quo and the improvement direction of the application of LED luminaire for road and street lighting in China. The EMI of control gear and the induction circuit for lightning protection widely applied in the LED luminaire for road and street lighting this time, and points out the disadvantage and improvement direction.

introduction
In recent years, in addition to the obvious technological progress of LED devices, various types of lighting fixtures have also made great progress in LED application technology. A few of the lighting products application level and most of the technical indicators have reached the latest release of the US Department of Energy (DOE). The level of indicators. However, due to the limitations of the technical level of most lighting electrical appliance manufacturers in China, there is still a significant gap between the products produced by most LED application companies and the qualified products that fully meet the requirements of various standards and requirements.
In June and July of 2009, the bidding units of the Six-Submersible Highway Project under construction in Anhui Province were 40 batches of 80 batches of products, and the number of bidding enterprises of Liu-Wu Expressway Project was 17 batches of 67 batches. Almost all the enterprises of roads and tunnel lamps participated in the bidding, but the test results of the bidding products were very unsatisfactory.
