Granada   ANDALUSIAN SPAIN Granada The bus journey from Madrid to Andalusia was strangely inviting. Andalusia is the southernmost part of Spain, also known as the Iberian Peninsula. The bosky landscape around was wild and cultivated. Cultivated with fleeting patches of olive orchards, which at some places spread far into the horizon? Traversing through the heart of Spain and somewhere at the back of my mind the landscape triggered the swashbuckling identity of the historical country. In search of El Dorado maybe one of the reasons why the Moors from Africa invaded Andalusia after crossing the strait of Gibraltar in the early 8 th century. They ruled this part of Spain till the 15 th century. Spain’s heartland, known as the Meseta, is a large plateau with an average elevation of six hundred meter above sea level is located in the centre of the Iberian Peninsula. Since Madrid lies on this plateau most of the journey up to Granada was through this fascinating and partly a

What is Human Centric Lighting? - An illuminating talk by Professor Warren Julian Human Centric Lighting Design is an old Concept, given that our circadian clock runs on a 24-hour cycle. But It was difficult to maintain the circadian entrainment effectively with traditional lights. With the advent of LED, having expanded color capabilities, and seamless control on color changes and dimming, a lot of research is underway to make our visual system respond more effectively to the light stimulus. Dynamic Tunable LED, varying lighting   has always been human-centric  Spectrum from 6500K to 2700K has increased the circadian effectiveness of the human system. Increasing daytime alertness and nighttime sleep can be addressed in the near future by acutely synchronizing the circadian system of human beings with proper doses of red and blue light. A brilliant presentation on Human Centric Lighting was made at the Hong Kong International Lighting Fair 2017 by Professor Warren Julian of Sy
