Paul Scheidt, Cree - Horticulture Lighting
"When you go into horticulture application the light output level directly correlates to the yield that you see in the plants. There is no buffer, when lights dim, the yield goes down. If something degrades very quickly and is 100% for one growth cycle then goes down to 90% for the second growth cycle, you will see a reduced yield. There is no room for adjustments." Paul Scheidt

A Lighting Designers Relativity of Light Performance
The LED will always be the superstar
of light sources. Their precise and clear lighting possibilities have been targeted by lighting planners and architects for the past ten years. The coming years will see the performance of the LED getting progressively closer to the spectrum of daylight and that will, in turn, generate biologically effective LEDs that are even higher in contrast and promise a new kind of feel-good light.

Dr. Jy Bhardwaj - The Future of Lighting Applications
DR. JY BHARDWAJ SAID: "LEDs get integrated into the infrastructure, or let’s say, embedded. Instead of points of light there will be ceilings of light or walls of light. LEDs will be integrated into work surfaces, tables and all kinds of different things".

Professor Shuji Nakamura
PROF. NAKAMURA SAID: "For violet LEDs we reach about 50-100 Acm-2 but the laser diode uses 3-10 kAcm-2 which is about 1,000 times higher than blue LEDs. This leads to very tiny chips in combination with the same phosphors such as YAG types. The light output is about 1,000 times higher than conventional LEDs with the same chip-size".

From Component to System, Andreas Weisl, CEO at Seoul Semiconductor Europe GmbH
The history of Light-Emitting Diodes
(LED) is quite short compared with
some other electronic device industries.
However, it has changed and
revolutionized the entire world of light
within a very short period of time. The history of Light-Emitting Diodes (LED) is quite short compared with some other electronic device industries. However, it has changed and revolutionized the entire world of light within a very short period of time.

Tech-Talks BREGENZ - Dr. Rubén D. Costa, Group Leader, University of Erlangen-Nuremberg
Light quality and costs of LED systems remain an important topic even though big improvements have
been made. New approaches are always welcome and stir up hope. It was exactly a year ago that LED
professional published the article by Dr. Rubén D. Costa, Liebig Group Leader at the University of
Erlangen-Nuremberg, about his amazing new „Bio-Hybrid“ white LED approach. At LpS 2016 his
presentation on the latest research results and improvements also won him the LpS 2016 Scientific
Award. Consequently, we just had to invite him to a Tech-Talk Bregenz! In the interview below he gives
us some interesting background information about why he started the project, how it works and what
he expects in the future. He also gives us his views on LEDs and lighting in general.

Lighting Up Smart Cities, Dr. Wu Chou, Huawei
Although streetlights have been
associated with cities for more than
a thousand years, they are rarely
considered for functions other than
luminary purposes. One of the distinct
features of streetlights is their
geographic location. In particular,
streetlights follow the roads and
streets that are the arteries of the city,
and at night they outline the city so it
can be seen from many miles away.

Tech-Talks BREGENZ - Prof. Christian Cajochen, Univ. Basel, Head of Center of Chronobiology
Human Centric Lighting has become a catchphrase used by industry and the press. But the press has also started reporting that research emphasizes the danger of LED lighting in connection to our health and has coined the term “Blue Light Hazard”. These claims have caused confusion amongst end users and throughout the lighting community. Prof. Christian Cajochen, Head of the Centre for Chronobiology
at the University of Basel - an expert on this topic - held a lecture at the LpS 2016 entitled “Light Beyond Vision”. Afterwards, LED professional seized the opportunity to talk to him personally and get some in-depth information about the risks and benefits of LED lighting.

Review of the LED Lighting Design Approach
A rapidly changing world leaves little time to react to new trends. Nokia lost its lead position because it failed to recognize market changes and take appropriate action in time. This has caused anxious industries to react quickly when changes come about. But, in some cases, such hasty
reactions can also be harmful.

Tech-Talks BREGENZ - Sebastian Huelck, Director Lighting, EBV Elektronik
Solid State Lighting has not only changed the way that light is generated but also how areas or objects
are illuminated. It has changed the whole industry and business. Sebastian Huelck, Director of Segment
Lighting at EBV Elektronik GmbH & Co. KG, discussed these changes and the new requirements for
modern distribution with Siegfried Luger and Dr. Guenther Sejkora. He explained the transition of
distributors from pure logistic specialists to one-stop shops and full service providers, and commented
on regional differences. He finished off by giving insights into the future projects of the company.

Lifetime and Reliability by Günther Sejkora
Although questions regarding lifetime
and reliability of Solid-State-Lighting
(SSL) products are essential for
customers, knowledge about it
is still fragmentary. It was easy to
give answers to these questions
in the times of conventional lamps
(incandescent, fluorescent, high
pressure): light output degraded over
time and end of life was reached
when light output fell below a certain
level or when the lamp “burned out”.

LFI 2016 Touts LED Lighting and Digital Control Technology Transformation by Dr. Nisa Khan
The 27th Annual LightFair International (LFI) conference was dominated by LED lighting coupled with internet-based control via wireless networks that continues to proliferate in today’s world. The world is increasingly becoming drenched with Internet of Things (IoT) discussions, demonstrations and for some, a certain level of implementation. Electric lighting
transformed our society for over 100 years, boosting our mood and association with the environment, culture, productivity,
and economic conditions. Such enormity pales in comparison to an unprecedented revolution that LFI describes as “Light and Technology in a New Language!”

Zhaga Meets Smart Lighting by Dee Denteneer
At first glance, the standardization of LED lighting components seems to be quite remote from the rise of smart, connected lighting and the Internet of Things (IoT). But the projected growth in penetration of smart lighting can only be realized through developments in high-volume electronics and
standardization. Such standardization is intended to remove arbitrary variations in components, making design and
implementation easier for manufacturers of smart LED luminaires, and enabling a supplier ecosystem. This is where
Zhaga comes in.
