One of The Misunderstandings About LED Public Lighting
The rapid changes in Led Public lighting(Classic) technology have led to a revolution in LED retrofitting. On a global scale, municipalities have chosen to convert old public lighting into new, more energy-efficient LED public lighting. Unfortunately, these changes have also led to incorrect information about LEDs, dark skies, security and the environment.
Myth: The use of LED public lighting reduces light pollution and “fits the dark sky” because of their high energy efficiency.
Yes, LEDs are more energy efficient, but the fact is ironic that as the city saves on electricity costs, it saves more light by buying more lighting. In most cases, especially in the United States, when the price of a product being produced and distributed falls, more things are often used, not less. In economics, it is called the Jevons Paradox.
“Governments and environmentalists generally believe that improving efficiency will reduce resource consumption and is an effective policy for sustainable development, ignoring the possibility of public opinion,” said Blake Alcott, a researcher who created the term.
The transformation revolution is particularly vulnerable to Jevons's paradox, as global demand for lighting continues to outpace supply, and urban lighting levels are higher, as LED public lighting makes new lighting costs lower.
LED technology has great potential to reduce light pollution - if done well. If not, it may make things worse. The municipality must consider all issues before implementing LED public lighting retrofits.
