Tech-Talks BREGENZ - Fred Maxik, Founder & CTO, Lighting Science Group

Tech-Talks BREGENZ - Fred Maxik, Founder & CTO, Lighting Science Group LED light in combination with advanced controls, and here especially IoT capabilities, opened several new options in lighting. In this context, the term Human Centric Lighting, and more recently, the term Biologically Active Light have become trendy. Fred Maxik, founder and CTO of the Lighting Science Group, who held the keynote speech at LpS 2017, recognized these opportunities in a very early stage when most other manufacturers were still struggling with the challenges of the new technology. In the interview he explains what his perception of light is and its importance in our lives. He gives insights into his philosophy and ideas on which criteria artificial lighting has to fulfill in order to live up to the promising terms „Human Centric Lighting“ and „Biologically Active Light“.

On Smart Luminaires

On Smart Luminaires In the time up to 2010, conventional luminaires with low or high-pressure discharge lamps with a luminous efficacy of about 80 lm/W were developed. The electrical power was dependent on the electrical power of the lamps built in the luminaire. From 2008 and likely until around 2020, luminaires with phosphorconverted white LEDs with one fixed color temperature, a constant luminous intensity distribution and a maximal luminous efficacy of about 140-160 lm/W are developed with an electrical power between 10 W and 300 W for different applications and dependent on the manufacturer. Therefore, a relative increase in luminous efficacy of 80 -100% in the context of the discussions on “energy efficiency” is being achieved. Read more »

Tech-Talks BREGENZ - Ken T. Shimizu, Research & Development Director, Lumileds

Tech-Talks BREGENZ - Ken T. Shimizu, Research & Development Director, Lumileds QDs have been a hot topic in lighting for a while already, but up until now they haven’t been adopted on a large scale in lighting. The adoption began in display devices because some of the technical issues were of less concern in this application. With continuing development, QDs are now also becoming interesting for general lighting applications. Ken Shimizu, Director of Novel Technologies and Devices, Research and Development at Lumileds, attended the LpS in Bregenz and made a presentation about the company’s QD technology. In this interview he gives some background information about the QD program and future steps. Read more »

Tech-Talks BREGENZ - Julia Frohleiks, Researcher, University of Duisburg-Essen

Tech-Talks BREGENZ - Julia Frohleiks, Researcher, University of Duisburg-Essen In his commentary on technical progress and innovation, Dr. Sejkora said: “In the early stage, in the first phase of its life cycle, technology is mainly driven by fundamental research.” He went on to say that we can never predict how a technology will develop. Researchers from the University of Duisburg-Essen, working in the Nano Energy Technical Center (NETZ), worked on this type of fundamental technology and their submission received the LpS 2017 Scientific Award. Ms. Julia Frohleiks, a Ph.D. student, was a major contributor to this research in the group led by Dr. Ekaterina Nannen and accepted the award in Dr. Nannen’s name. In the following interview she gives some background information and discloses future research possibilities. Read more »

Can You Show Me the Next S-Curve, Please?

Can You Show Me the Next S-Curve, Please? The evolution of technologies is often described using the “S-curve” model. In the early stage, in the first phase of its life cycle, technology is mainly driven by fundamental research. Only a few players are active at that time and innovation steps are quite large. In the second phase, early adopters start to develop products and bring them to market. This phase is characterized by huge investments. In the third phase, more and more players enter the technology field, competition becomes important and development speed of the technology decreases. In the last phase, the technology is mature, (nearly) everybody can use it, there are fewer margins and the technology should be replaced by a new one. Many of the SSL technologies have meanwhile reached maturity. Where are the upcoming technologies, what will be the next S-curve? Looking at technology discussions and lectures at LpS 2017 I tried to find answers to these questions. Read more »

Brave New World and the Dualism of Light(ing)

Brave New World and the Dualism of Light(ing) The lighting business has been quite predictable over a long period of time. Technical changes were introduced slowly, dominated by a handful of leading companies, and mostly due to new, but not disruptive light sources. The life of engineers was mainly determined by a manageable number of parameters: Lighting requirements, light source parameters, costs, product dimensions, and the odd, required feature.

Paul Scheidt, Cree - Horticulture Lighting

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."

A Lighting Designers Relativity of Light Performance

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.

Professor Shuji Nakamura

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". Read more »

Lighting Up Smart Cities, Dr. Wu Chou, Huawei

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. Read more »

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. Read more »
