Street lights in Chattanooga, Tennessee are very smart and they can fight crime too. A Chattanooga company, Global Green Lighting, has developed the smart street light of the future. As described in a profile in The Atlantic Cities magazine, the city of Chattanooga was having gang problems in Coolidge Park, one of their city parks. The situation got so bad in 2011 that the city was facing a decision to close the park at dusk or light the park with gigantic flood lights for safety. Along came Global Green Lighting to save the day!
Global Green Lighting installed a new smart LED lighting system in Coolidge Park. Not only does the new LED lighting system provide better, less expensive lighting for the park, but the new wirelessly enabled LED lighting system offers the city the ability to work smarter. Each light can be controlled specifically to turn on at dusk and turn off at dawn. Each light also can turn into a crime fighting tool like a search light or brighten to illuminate a crime scene or trail a suspect as he or she sprints down a road. While park goers can’t activate the changes in the LED lighting, the lights can be controlled right from a police cruiser on site.
The LED lighting system also brings other advantages for the city. They can flash warning signals in emergencies like weather alerts. Further, they’ll be wired into the city’s power system and broadband network so the city can plug in devices like air quality sensors, video cameras, or WiFi routers.
After a successful test of 350 lights last year, Chattanooga worked with Global Green Lighting to replace the city’s 26,500 streetlamps at a cost of $18.1 million. The city estimates that the new lights will save $2.7 million each year when the project is completed in late 2013 and the system will pay for itself within seven years. Further, the system is so smart that it will alert the city when one of the LED lights is having a maintenance issue, letting them know which one needs service.
