Having Some Fun: Smart Lighting is going to be messy
... Don't let the headline worry you... 'smart' lighting is going to be great, and it will work well, but it is most assuredly going to be a somewhat messy process to go from today's versions of controllable lighting, to tomorrow's actual smart lighting. In terms of impact players, Philips... Read

Up to 1.1 Gigabit per Second LiFi Transmission Using Micro LEDs is Possible Over 10 Meter Distance, According to Researchers LIGHTimes News Staff
April 10, 2014...Harald Haas, a University of Edinburgh professor, chief science officer
(CSO), and co-founder of pureLiFi, and his team demonstrated that up to 1.1
gigabit per second (Gbps) can now be transmitted using light from micro LEDs
over a distance of 10 meters with less than 0.5W power. LiFi is a term
reportedly coined by professor Haas in which light is used to transmit data
wirelessly in a way that enables full networking capabilities similar to WiFi.
However, LiFi has greater spatial reuse of bandwidth
The process uses just 5% of the power of a typical 10W LED light bulb.
Therefore, lights can be dimmed while maintaining high LiFi data rates and
coverage. Furthermore, the researchers found that the distance at which 1 Gbps
is possible with a single color LED is 10 times larger than previously
EPSRC funded the work as part of the Ultra Parallel-Visible Light
Communications (UP-VLC) program grant. Haas collaborated with partners from the
Institute of Photonics at the University of Strathclyde, the University of
Glasgow, and the University of Oxford.
pureLiFi successfully demonstrated of the first commercial Li-Fi product,
Li-1st, at MWC 2014 and CeBIT 2014 in March and added a second production run
of the Li-1st to meet the demand from industry customers. The new production
run is scheduled to ship this month. Haas founded pureLiFi (formerly pureVLC)
as a spin-out from the University of Edinburg. The company produces LiFi
drivers and receivers.
Professor Haas said, “Li-Fi is revolutionizing wireless
communications and showing that Li-Fi can be the enabler of the emerging
Internet of Everything. By transmitting data at speeds above 1 Gbps and record
distances of 10 metres at a fraction of the power of typical LED bulbs, we
continue to make the technological leaps and bounds that make Li-Fi a
technology that could transform the way we use the internet in the near
Tetris is Played on Cira Centre in Philadephia LIGHTimes News Staff
April 8, 2014...Two sides of the 29-story Cira Centre in downtown Philadelphia were
transformed into a giant game of Tetris as part of the kickoff to Philly Tech
Week on Saturday. Sam Robinson was one of the lucky participants who got to
play the famous game on the 100,000 square foot screen formed with LED lights.
Tetris has been played on buildings before, but the size of the game on the
north and south faces of the Cira Centre building may be a record.
“It has been probably 15 years since I played Tetris last on a
Game Boy, and it’s much different playing on the side of building
that’s a half-mile away,” Robinson said.
Organizers hoped that the grand exhibitiion would inspire players and
onlookers to imagine technology's possibilities. The hundreds of LEDs mounted
on the building's glass walls normally display patterns, but on Saturday night
enormous shapes fell and piled up as players attempted to maneuver the falling
puzzle pieces so that an entire row could be filled and then erased before the
pieces piled up to the top.
Frank Lee, associate professor of digital media at Drexel University,
oversaw the creation of the giant game on Cira Centre to celebrate the upcoming
30th anniversary of Tetris. Tetris was created by Russian computer programmer
Alexey Pajitnov in 1984 and was eventually put on numerous gaming platforms.
The game's popularity took off after it was put on the original Nintendo
Lee addressed a crowd of onlookers saying, “This project began as
a personal love letter to the games that I loved when I was a child –
Pong last year, Tetris this year, but it ended up as a way of uniting the city
of Philadelphia." Lee previously set the Guinness World Record for the
largest architectural video game display for playing Pong on one side of the
Cira Centre last year.
Curved TV Screens Jump Into Global Market LIGHTimes News Staff
April 8, 2014...NPD Display search forecasts that shipments of curved TVs will reach almost
800k units in 2014 and are predicted to be more than 6 million units by the end
of 2017. According to the company, curved TV is a feature that is expected to
reach its peak in LCD TVs in 2016. Then, growing shipments of OLED TVs are
predicted to increase curved TV shipments in 2017.
After two straight years of declining revenue from the global TV market,
brands are exploring numerous avenues to revitalize the business such as curved
screens, OLED displays, and increased resolution (4K or Ultra-HD).
“The novelty of curved screens is expected to wear off with time,
leading to shipments peaking and then trailing off,” said Paul Gray,
director of European TV research for NPD DisplaySearch. “Even so,
curved screens will have completed the important task of differentiating new
high-end models, thereby helping to boost overall value in the global
Curved LCD displays first emerged at IFA 2013. Samsung, LGE, and several
Chinese brands showed curved screen LCD TV models at the 2014 Consumer
Electronics Show (CES), but the companies are hedging their bets with other
features. “Brands are not staking their futures only in curved screens or
any other single feature, but are instead exploring a whole mix of features to
attract TV buyers,” Gray noted.
OLED TVs are getting much attention, but they still face significant
manufacturing difficulties. NPD Display Search says that at best only 100K will
ship in 2014, and annual shipments are expected to reach only over in 2016.
“LCD has proved a tough act to beat, because it is a mature,
efficiently-manufactured technology, with a surprising amount of room for
innovation,” according to Gray.
Companies are racing to get the best screen resolution. This year, Netflix
announced 4K streaming services to support expansion of the category. The
number of ultra-high-definition (UHD) 4K TVs shipped in 2014 are forecast to
exceed 12M units and increase to 62 million in 2017. China will reportedly
dominate demand and shipments of 4K TVs with an 83% share of 4K TV shipments in
2013, falling to 46% in 2017, as other countries catch up. “4K TV is
currently grabbing a lot of headlines, but it would not have been possible to
deliver 4K, had there not been investment in connected TVs, over the past five
years,” Gray said.
April 3, 2014...German automotive lighting company Hella, has used bent OLED modules in a prototype for combination rear lamps. A total of 28 of these differently shaped OLED modules produce three-dimensional, illuminated structures. LG Chem and BMW collaborated with Hella to develop the prototype design , which was unveiled at Light + Building 2014. This design sample will be showcased at the stand of the OLED specialist, LG Chem.
OLEDs, which are made up of are very thin, organic, semi-conductor layers, generate light over a complete area. The OLED's bent shape is made from a flexible OLED substrate. Hella notes that the flexible OLED can be made into virtually three-dimensional shapes with bend radii of just a few millimeters. Hella reports that it is in the process of developing technologies for a rigid, bent OLED module.
S+H Starcloth Serves as Backdrop for Crufts Dog Show LIGHTimes News Staff
April 3, 2014...S+H Technical of Devon, UK, built a custom ‘Crufts’ LED sign and
supplied quantities of its standard RGB LED starcloth for the main show ring of
the 2014 edition of the world’s largest dog show. Crufts was staged at
Birmingham, UK’s National Exhibition Centre (NEC), the LG Arena. The
Kennel Club initiated the idea of the sign and the starcloth. The starcloth was
first used in 2012 by Jon Pope, the show’s lighting designer since 2009.
The star cloth creates a highly visible and flexible ‘Crufts’
identity in the form of the color changing sign that has augmented the
background of all the presentations in the ring.
The main show ring served as the hub of the action for all four days of the
event which culminates in the renowned ‘Best in Show’ competition.
It is broadcast on More 4 and Channel 4 national TV and also streamed daily on
YouTube. Pope wanted to complement the show's lighting for the ring with a
dramatic backdrop. He need something that could change the mood and feel of the
space and would look great on camera, especially as a visual filler for the
‘back’ of the shots. Pope had to satisfy the demands of both the
live event, and the live TV coverage. At the same time, he had to give all
involved ideal conditions in which to work.
The S+H RGB starcloth, which measured 30 meters wide by 10 meters high,
formed the main backdrop along the closed sides of the ring. Three 3 x 3 by 4.5
meter runs of RGB Starcloth clad one of the TV camera towers that was also
frequently in shots from other cameras.
The custom Crufts sign was made up from ShowLED RGB LEDs, with a 40mm pitch
and approximately 1200 lights. It measured 6.5 metres in length with a 2.5
meter drop, and 8 -channel controls enabled full color mixing, and chasing,
etc.... The sign was prominently displayed throughout the duration of the
event. The starcloths and the sign were DMX controlled by Pope via his ETC
Congo lighting console, through which he also controlled the generic lighting
Pope commented that S+H's pricing was competitive and that they were
“Very helpful and constructive in making suggestions about how the
Crufts starcloth should be built.” He added that both the starcloth
and the Crufts logo brought an “Impressive backdrop to the event,
which looked great on camera.” Both items gave him a large
back-cloth and enabled him to “Greatly enhance the lighting and ambience
of the space.”
S+H’s Terry Murtha commented, “He had a very clear idea of
what he wanted and listened and took onboard our ideas and experience in this
specialist area. The results looked truly spectacular!”
Pope worked on the show which was directed by Nick Brooks-Ward, with Moving
Light Operator Phil Cole and Production LX Nigel Hollowell Howard. Rental
company Neg Earth supplied all the lighting equipment. Crufts 2014 ‘Best
In Show’ winner was Ricky the standard poodle.
Consumer Demand for LED Backlight Falters as Demand for LED Lighting Rises LIGHTimes News Staff
April 3, 2014...While demand for LED chips for backlight applications in display screens is
expected to decline, both LED lighting sales and total shipments of LED chips
are increasing. According to NPD DisplaySearch, worldwide LED lighting chip
sales are expected to rise from $1.1 billion in 2013 to $3.4 billion in 2017.
The company forecasts that overall LED chip demand (measured in standard units
of 500 × 500 micron chip size) is expected to grow from 17 billion in 2012 to
61 billion in 2014. However, NPD Display Search predicts the market for LED
backlight chips for TVs and other display applications will begin declining
The company says a combination of slower growth in LED-backlit LCD TV sales
and efficiency increases have resulted in a reduction in the number of chips
used per backlight and the demand. LED backlight chip sales reached $2.0
billion in 2013, but are NPD DisplaySearch expects them to decrease to $1.4
billion in 2017. However, the company points out that consumer demand for LED
lighting has increased since 2012, and the company expects it to continue
growing through 2017.
"LED market observers have been expecting huge growth in the LED
lighting market for a long time, and it's finally here," said Steven Sher,
LED backlight and lighting analyst for NPD DisplaySearch. "Significant
growth in consumer lighting is helping to keep the LED market on an upward
trajectory, even with ongoing declines in backlight demand."

Philips and Saint-Gobain Ecophon Launch Ceiling Lighting Attuned to Body's Circadian Rhythm LIGHTimes News Staff
March 26, 2014...Philips and Saint-Gobain Ecophon, a supplier of acoustic systems is
launching a new version of their jointly developed light emitting ceiling. The
new active SoundLight Comfort Ceiling Tunable White is designed to promote
vitality and productivity through leveraging the human body’s natural
The luminaire system incorporates programmable lighting controls. Throughout
the work day, the lighting controls change the brightness and warmth of office
lighting to simulate daylight. Simulating daylight can reportedly help reverse
a person's feeling of diminished energy from being stuck inside. SoundLight
Comfort Ceiling Tunable White simulates ‘daylight'. This simulated
daylight helps the body maintain its natural connection to the sun.
“Saint-Gobain Ecophon and Philips jointly developed and released
SoundLight Comfort Ceiling in 2012. Now with dynamic lighting we take the next
step towards an optimum working conditions when it comes to light and sound
absorption, enabling people to perform at their best and keep the balance in
their biorhythm,” said Gert-Jan van Doormalen, president of the
After the product's launch in 2012, research done at the Stress Research
Institute of Stockholm University examined the effects of the SoundLight
Comfort Ceiling on employee well-being and comfort in the workplace. According
to the findings, nine out of ten office workers agreed that SoundLight Comfort
Ceiling contributed to an environment in which they like to work. Additionally,
the majority of those involved in the research stated that the ceiling created
an atmosphere that was more stimulating, lively and inspiring than the
conventional lighting that they used previously. Office workers who tested the
SoundLight Comfort Ceiling experienced greater visual comfort than those when
they used traditional office lighting.
“Many people suffer from light deficiency especially in the
winter; have sleeping problems, are more tired, and even depressed as a result,
’’ said associate professor, Arne Lowden, Stockholm
University, Stress Research Institute. “The preliminary results using
SoundLight Comfort Ceiling show that employees feel less stressed and more
energetic as a result of improved lighting.”
‘’Innovation at Philips is based on our understanding of how
light can be used to positively impact people – we know it can soothe,
energize and relax us, aiding productivity and concentration,
’’ said Menno Kleingeld from Philips Lighting.
‘’We applied this knowledge to develop SoundLight Comfort
Ceiling Tunable White in partnership with Saint-Gobain Ecophon, to help create
comfortable and inspiring workplaces.’’
