Interviews & Tech-Talks BREGENZ (TTB)
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.

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”.

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.
