Typical cases of Expressway LED lighting application

In low carbon energy environment, at present, the high-speed road LED lighting application case increased, among them, the national highway the first large-scale application of LED street - Shenzhen Expressway Qinshang LED lighting contract energy management project, the most famous.

Previously, other domestic provinces highway has gradually began to use LED lights to replace the original highway toll plaza, toll greenhouses, service area, tunnel lamp using incandescent lamp, fluorescent lamp, high-pressure sodium lamp etc..

LED tunnel lighting in the high-speed road, so far the world's LED lighting in the high-speed tunnel on the largest engineering applications - Anhui province six highway tunnel lighting project, but also quite representative.

In recent years, in the national energy conservation and emission reduction policy call, a number of domestic highway launched LED lighting, have successful experience, but also the lessons of failure. Now the successful cases show for the industry reference.

Application case of LED tunnel lamp lighting on Expressway

According to incomplete statistics of highway tunnel at present in our country, the completion of the extension has been more than 2600 kilometers, and with the improvement of transportation infrastructure, highway construction is the geological environmental conditions worse development of mountainous areas, highway tunnel will be further extended. In order to ensure traffic safety, tunnel lighting is an important part of highway construction. In accordance with the provisions of Chinese design code of highway lighting, tunnel length of more than 100m should set the lighting facilities, and each extension of KM tunnel lighting load should not be less than 60kW, according to the average daily open 10 hours, the average annual consumption of 216 thousand degrees (equivalent to 76 tons of standard coal), energy consumption is huge. In addition, the cost of maintenance and renovation, so that the highway tunnel lighting has become a heavy economic burden on the road operator. Energy saving and consumption reduction and security are the key technical problems for construction and operation units.

So far the world's largest engineering application of LED lighting in high-speed tunnels

Anhui six highway tunnel lighting project

In 2009 on the micro channel in Anhui in July through the bid to obtain six high-speed road tunnel project LED LED tunnel lamp lights near the order of 10 thousand. Through nearly half a year of production, installation and commissioning, the company provides the LED tunnel lamp indicators have reached or exceeded the tender requirements of the project, has been successfully passed the project acceptance in 2010 of January. It is reported that this is by far the world's largest engineering application of LED lighting in high-speed tunnels.

Name of the project: Anhui six highway tunnel lighting project

Two, project background

Anhui province (Lu'an - Qianshan) six potential highway as approved by the Ministry of communications of the national key construction project of highway, the tunnel lighting project is divided into four sections, a total length of 45223 meters, of which first, 2, 3 tenders for LED lamps, fourth tenders for the traditional high pressure sodium lamp, the installation of 20658 sets of tunnel light. The project in June 2, 2009 by the Anhui provincial highway engineering construction headquarters is responsible for the tender, in the light of the third successful bid for the longest section (contract number: LQZM-003), a total length of 19600 meters.

Three, installation time

The project began to supply from 2009 08 to 2009 09, 30 August installed.

, four installation site

The project has a total of 5 tunnels, namely: the old Ridge Tunnel, rouge tunnel, Castle Peak row tunnel, the old house tunnel and the tunnel.

Five, installation of LED tunnel lamp name, quantity

The project was originally planned to install the "micro" brand LED tunnel lights 6460, of which 100 watts (AL-T10 type) of the 1360 sets, 50 watts (AL-T05 type) sets. The actual installation of "micro" brand LED tunnel lamp 6554, of which, 100 watts (AL-T10 type) of the 1252, 50 watts (AL-T05 type) of the 5302.

Six, opening time

Trial run time: October 2009 - November

Opening hours: December 2009 08.

Seven, operation

Since the installation of the project has been officially used for nearly 2 years, the operation time of more than 16500 hours, the product has been a continuous test of the spring and autumn of the two seasons. From the micro company after sales tracking and customer feedback information, the smooth operation of the project, excellent product quality. Up to now, due to the installation, weather, power grid, the quality of the product itself and other reasons for the emergence of the failure of about 63 lamps, accounting for 0.96% of the total number of running lamps. By actual measurement, micro LED tunnel light intensity and initial decay is only about 2.9% compared to the average illuminance.

After preliminary estimates, the project and the traditional high-pressure sodium lamp tunnel light, the use of micro LED tunnel lights to save electricity has fully recovered the initial investment, and save considerable maintenance, maintenance costs. The operation of the project, not only produced a huge economic benefits, but also a large number of reducing carbon dioxide, sulfur dioxide and dust emissions of greenhouse gases, significant social benefits.

It can be seen that the current high-speed LED applications are mainly reflected in the high-speed road LED tunnel lighting, in the application and energy saving have advantages. In the case of application, there are many, such as:

In October 2007, the tunnel LED lighting group in Anhui transportation group construction in Tongling to Mount Huangshan Expressway Tunnel began trial, the energy saving effect is better. After calculation, the road length of 422 meters of Huang Bang Ling tunnel, the total power of the traditional left hole high-pressure sodium lamp is 115 kilowatts, the average power consumption of 1150 degrees; the right hole using LED lighting a total power of 40 kilowatts, the average power consumption is 400 degrees, run for half a year to save electricity 110 thousand yuan;
