The United States LED street lamp market application

The lamps and lanterns of lamps, which provide road lighting function.Traditional street lamp generally use high intensity discharge lamps （HID） as a light source, such as high pressure sodium （HPS）， metal halide lamp （MH） and mercury lamp （MV）.

LED applications in lighting has a unique advantage, because LED is a directional light, durable, and long product life. Currently, part of the City of the United States has started LED street lighting retrofit projects, such as the southern West Bank city of Los Angeles, California USA, completed the city's more than 150,000 LED lights transformation, the transformation of energy-saving 63% compared to the previous, saving $ 8 million per year.

LED prices compared to high pressure sodium, metal halide lamps and mercury still a lot more expensive, for example, in 2014 the market price is high pressure sodium $ 1.2 / thousand lumens, a metal halide lamp is $ 2.1 / thousand lumens, mercury is $ 2 / thousand lumens, LED street lamp market average price is $ 58 / thousand lumens.

According to statistics, the LED street lamp luminous efficiency for an average of 87 2014 lumens per watt, and the best level can reach 137 lumens/watt, and HID lamp is the best luminous efficiency levels of 130 lumens/watt.LED street lamp rated life over 50000 hours, usually is 3 times of high intensity discharge lamp life.

LED street light in use in the United States in 2012 to 2012, accounts for only 3% of the total amount, to 2014 LED lights in the dosage for 5.7 million sets of 4.4 million sets （growth）， about 13%, and in 2014 the United States street lamp always in the consumption of about 45 million sets.LED road lighting application promotion success is mainly attributed to the energy saving lighting renovation project of the city, by government subsidies, the project to replace the traditional HID lamps, achieve the goal of energy conservation and emissions reduction.
