Lighting is in the midst of a technological revolution. More than one hundred years after Thomas Edison kick-started the lighting industry by inventing the first commercially viable incandescent light, the industry is undergoing a radical transformation.
The move from fluorescent to LED lights will have a significant impact on energy use, cost, and the carbon footprint of lighting. But what seems like radical change is only the beginning of the story.
In a second technological revolution, we are in the process of moving light from AC power to Power over Ethernet. By combining the transmission of power and data on one low-voltage cable, we are effectively integrating light into the Internet.
The possibilities of digitally powered and controlled lights go far beyond what we could have imagined just a few years ago. Powering lights using Power over Ethernet technology makes a separate power network redundant. The same network that provides control to all kinds of digital devices like computers or phones can now also provide both controland power for the LED.
What advantages does this provide…read the full article here.
