The benefits of LED street lighting are numerous. Because they last longer and use less energy than their traditional equivalents like incandescent, halogen, or fluorescent lights, they are cost-effective and sustainable. The advantages of LED street lights and public lighting are listed below.
How might LED street lighting help cities become more sustainable?
Due to their decrease energy usage, LED street lights can assist cities in becoming more environmentally friendly by reducing their carbon impact. In order to reduce costs, conserve energy, and improve the adaptability, flexibility, and efficiency of public lighting infrastructure. LED lighting systems can also connect with smart technologies.
LED street lighting’ energy efficiency
Due to their low heat output, LEDs are far more energy-efficient than their conventional counterparts since they need much less electricity to provide the same quantity of light. In contrast, around 80% of the energy in fluorescent lights and 90% of the energy in incandescent bulbs is converted to heat. LED lighting is between 40 and 60 percent more energy-efficient than conventional lighting methods.
The fact that LED street lights use less energy and produce less pollutants. Their conventional counterparts is one of its benefits. According to the World Bank, switching to LED outdoor lighting in the US alone can reduce carbon emissions by the same amount as removing 8.5 million automobiles from the road for a year.
The extended lifespan of LED lighting products—which outlive conventional illumination—is another advantage of LED street lights. For instance, LED bulbs can last 30 times longer than incandescent ones and three to five times longer than fluorescent ones.
Excellent Colour Rendering
The exceptional colour rendering of LED street lighting reproduces natural light and presents colours in a more realistic way. Making objects easier to see at night for vehicles and pedestrians improves traffic safety and road conditions.
It takes incandescent lamps between 0.1 and 0.2 seconds to turn on. It can take tens of seconds to ten minutes for gas discharge lamps. Like high-pressure sodium and metal halide lamps, to reach a stable light output. They need 3-6 minutes to cool down after being switch off before they can restart. In contrast, LED lights can function regularly in an on/off state. And take only tens of nanoseconds to turn on, with no wait time before restarting.
