Euroshop took place in Dusseldorf, Germany, last week. The event is the biggest retail themed trade show in the world and this year there were plenty of lighting developments to get excited about. From indoor positioning to interactive flooring, we have the low-down fresh from the Messe. Lux Review 14 March 2017.

Li-Fi crucial to the future of lighting, says LED inventor

Laser lighting is currently being used in cars, but the technology is not cheap, something that is set to hold back the product’s commercialisation.
Speaking at Academia Sinica, in Taipei, Dr. Nakamura stated that LED has now reached a ‘stage of maturity’ and manufacturers are seeking out new markets where they can thrive into the future.
Nakamura named Li-Fi and laser lighting as two crucial areas the LED industry needs to concentrate on in order to further their businesses successfully.
The Nobel Laureate also stated in his lecture that there has been areas in which the advancement of LED has surpassed even his expectations.
For example, researchers in Taipei have recently begun using LEDs to separate malignant cancer cells from normal cells.
Most recently, Nakamura has been dedicating his time to developing laser lighting, which he hopes, will one day replace LED.
Laser lighting has already been used successfully in car development. Automotive headlights that feature laser lighting are able to project light as far as 600 metres, which is much longer than the 300 metres managed by LED.
Nakamura predicted that should Li-Fi and laser lighting combine, then the Li-Fi technology would be able to transfer data at speeds up to one hundred times faster than Wi-Fi can currently manage.
However, laser lighting does not currently have the same efficiency benefits as LED and is, in comparison with LED, quite expensive, costing up to ten times more than its sister technology.
Nakamura is currently teaching at the University of California in Santa Barbara, with his two fellow researchers, Isamu Akasaki and Hiroshi Amano, who together received the Nobel Prize in Physics in 2014 for ‘developing the manufacturing technology of the blue LED and fostering the emergence of bright, power-saving white LED.’

The LED revolution has concluded, prices are falling and the industry’s attention is turning to the digital world, to the internet of things and smart cities.
In a Lux Today special edition, we examine smart cities and ask how is lighting improving our urban environments? Why are more and more cities adopting smart technology? And why does the lighting industry need to move quickly to take advantage of this new innovation?

LEDs could be used to link appliances into the ‘Internet of Things’.
LEDs can do double duty and illuminate a room whilst joining together the Internet of Things.
Experts at Disney Research and ETH Zurich believe that it is possible to create a network of luminaires that can send messages to each other, while having no effect on the level of lighting they emit. The experts have designed a Visible Light Communications system that is able to connect to appliances and wearable devices.
‘LED light bulbs mounted on the ceiling or in free-standing floor lamps easily cover a room, serving as illumination while at the same time creating a room-area network that allows data exchange between light-emitting devices’
Markus Gross – vice president Disney Research
‘LED light bulbs mounted on the ceiling or in free-standing floor lamps easily cover a room, serving as illumination while at the same time creating a room-area network that allows data exchange between light-emitting devices,’ commented Markus Gross, vice president at Disney Research.
‘Even if a bulb is not needed for lighting and is switched off, it can still serve as a receiver of signals from those devices,’ he added.
The research team used commercially available, off-the-shelf LED light bulbs to create the system. The fixtures were then modified and a System-on-a-Chip, or SoC, running an embedded version of Linux was added to each luminaire, as well as photodiodes to enhance the sensing of incoming signals.
The team’s completed prototype is able to create stable networks that can support the low bandwidth applications typical of most ‘Internet of Things’ devices.
‘Interconnecting appliances, sensors and a wide variety of devices into the Internet of Things has many potential benefits, but using radio links to do so threatens to make the radio spectrum an even scarcer resource,’ commented Markus Gross, vice president at Disney Research. ‘Visible light communication networks act to conserve the radio spectrum.’
