The first international design seminar dedicated to accent lighting in architectural lighting took place at the Aegean coast of Kea on November 20-24th, 2014. The seminar was held under the motto „Rethink the night!“ and left a lasting impression.
Greek Committee for lighting, led by President G. Paissidis proposed a series of experiments with lighting to show interesting effects due to changes in object parameters such as saturation and hue.
It is known that LEDs consist of a semiconductor chip which emits light energy near ultraviolet level and phosphors which converts the energy into radiation of a wide spectrum, which is visually perceived as a white color. The luminous flux is directly dependent on the radiation power of the crystal which is directly proportional to the operating current and inversely proportional to the transition temperature. It is obvious that the radiation increases with increasing current and decreases with increasing temperature.
From the viewpoint of saving the most important is the indicator of the light output: radiation power ratio to the power consumption.
It therefore becomes apparent the use of modern energy-saving lighting. But, unfortunately, modern lighting systems have their drawbacks:
1. The rather high price,
2. Lack of proper use experience,
3. A large number of defective products,
4. Parameters of the light sources do not meet the standard documentation,
5. Elevated pulsation of light. Let’s consider how the ripple of light effects on the human body.
In applied lighting engineering it is appropriate to associate the luminous temperature of different types of candlelight sources with natural sources of light.
The Hellenic Illumination Committee (CIE Member) in cooperation with the Department of Master Studies in Lighting Design of Wismar University of Applied Sciences / DE the Design Forum of Coburg & the Kuffner Observatory of Vienna is staging an International Lighting Design Workshop (ILDW) on the aegean coast of Kea from 20.10.2014 to 24.10.2014 under the auspices of Kea Municipality.
