LED Street Light Project in San Jose, Pittsburgh, USA
Pittsburgh, Pennsylvania, and San Jos, Calif., are planning to refit LED streetlights, but they are not comprehensive.
Among them, Pittsburgh plans to replace 40,000 traditional street lights with LED street lights, while San Jose is preparing to replace 62,000 traditional street lights with new LED street lights.
Through LED light source technology, it is expected to reduce the energy cost of street lighting by half, and change its lighting intensity and service life.
The City of Pittsburgh estimates that it can save more than $1.4 million annually in energy and maintenance costs. GuyCosta, director of the city's public works department, pointed out that Pittsburgh's annual energy consumption and maintenance costs for street lamps are $4 million. If it is replaced by LED street lights, it is expected to be reduced to $1.4 million. The open tender contract includes replacement, installation and maintenance of LED street lights at a cost of $25 million.
For decades, San Jose’s drivers, pedestrians, and police have generally complained about the city’s yellow streetlights, which are easily confused with traffic signs and make the car’s colors and fences look strange. In the spring of 2009, the city plans to replace traditional street lights and is working hard to raise a budget of about $20 million.
US Climate Proposal: LED Street Lights in Los Angeles
A report from the Clinton Climate Proposal, former President Clinton announced the Clinton Climate Proposal (CCI) outdoor lighting program, which will be a city for large-scale LED streetlight renovation projects to date.
In five years, the Los Angeles City Street Lights Bureau will replace the existing 140,000 street lights in Luocheng with LED street lights, which will not only improve the lighting quality and reduce power consumption in Los Angeles, but also help during the transformation process. The city saves money.
Although typical street lamps have a service life of 4-6 years, LED street lamps have a longer service life and are expected to last 10-12 years. This new, white LED street light is more durable and resistant to damage than other street lights. This will not only reduce the frequency and cost of repairing street lights, but the city will also save a lot of labor and raw material costs.
The increased life of the street light also means that the street light provides urban residents with more reliable street and sidewalk lighting. In addition, Los Angeles is committed to using LED lighting - night sky artificial lighting to alleviate the sky glow.
Once the renovation project is completed, Los Angeles will save 40% of the electricity consumption for street lighting and reduce carbon dioxide emissions by about 40,500 tons per year, which is equivalent to reducing 6,700 cars per year on the road.
In the next seven years, the city will save a total of $ 48 million in capital and reduce carbon dioxide emissions by 197,000 tons. After repaying the seven-year loan, it is because of the implementation of this lighting renovation project that Los Angeles will continue to save 10 million US dollars every year. In addition, the loan will not adversely affect the city, and the amount of money to be repaid will be covered by the current savings from energy and maintenance.
The LED retrofit project also includes the installation of remote controls for the city's 140,000 street lights. When a street light fails, the unit reports directly to the street light bureau and repairs it immediately, allowing the staff to optimize their repair service.
The outdoor lighting program between the Clinton Climate Proposal (CCT) and partner cities uses energy, procurement and project assistance to improve the energy efficiency of street and traffic signal systems.
