Topic: Applications A few days ago, the University of Pittsburgh's Sustainable Engineering Mascaro Center announced an evaluation report for street light replacement lamps. The evaluation study compares LED lights with metal halide lamps, high pressure sodium lamps and induction lamp technology, and the results show that LEDs are winners.
The research team's report shows that although the initial input cost of LED lamps is too high, LED street lamps consume less than half of the energy. Compared with metal halide lamps and high pressure sodium lamps, the service life is more than 5 times, and more light sources can be produced. Gas-sensing lamps are another emerging technology. In terms of energy conservation and light efficiency, gas-sensing lamps will surpass LED replacement lamps, but they will have a greater impact on the environment during use.
The report also shows that if the city of Pittsburgh uses LED street lights, it will save $1 million in energy costs, and $700,000 in maintenance costs will also reduce carbon dioxide emissions.
