Applications support many different institutions throughout the year bringing together light and light is the sponsor of the plans. Also Ibn an optical heysem 2015 book 1000 th 200 th Fresnel of revealing the wave structure of light, electromagnetic waves, Maxwell's 150 th your description of Einstein's space-time showing the influence of light of the 100th anniversary of the discovery of cosmic Microwave background radiation is the 50th and fiber optics. 2015 Steering Committee Chair John Dudley light-years of this year, according to demonstration of the potential of light technologies in terms of solving the problem of politicians is an extraordinary opportunity. Light energy, sustainable development, climate change, health, communication, and agriculture in many different areas such as cost-effective solutions. Innovative lighting solutions, light pollution, energy consumption and reducing environmental impacts while at the same time, we, too, makes us realize the beauty of the universe in a dark sky. Light years offers a unique opportunity to increase awareness in this field. Replace light bulbs very energy efficient-efficient lamps and LED lights I wish to be a new beginning for you to use.
