International Year of Light and Light-based Technologies (IYL): a United Nations program

video: LIGHT2015 -- Lighting the Future

LIGHT2015 -- Lighting the Future, a video developed by the National University of Galway as part of the LIGHT2015 Project aims to encourage venture capitalists and industry who have not yet invested in photonics innovation to do so, pointing out that photonics supports 10% of the European economy but its impact is much greater. The creators of the video hope to inspire others about the opportunities for business and growth now and in the future. (Run time 4:38.)

International Year of Light in Washington, D.C.: Light at Play Radiance Orb

Fun was the word of the day at the Wonders of Light: Family Science Fun day held at the Smithsonian National Museum of the American Indian. Over 500 children and parents participated in activities as diverse as building kaleidoscopes to being a science reporter for a day. An evening symposium and reception followed at the National Academy of Sciences. Light for a Better World: A Celebration of U.S. Innovation saw speakers from the National Science Foundation, GE Lighting and AIM Photonics -- and two Nobel Laureates. Read the SPIE press release.

image for IYL photo contest The SPIE International Year of Light Photo Contest was organized by SPIE Professional magazine to raise awareness about light and light-based technologies during IYL2015. International judges selected 3 photos depicting light and light-based technologies in daily life for top prizes (at left, the third-place winner). Another 32 photos were eligible for the People’s Choice Award. Voting is now closed and results will be announced soon!

As the international society for optics and photonics, SPIE is delighted to play a key role in the International Year of Light as a Founding Partner.

The International Year of Light 2015 recognizes the importance of raising global awareness of how light-based technologies promote sustainable development and provide solutions to global challenges in energy, education, agriculture, and health. Listen to Nobel Prize winners invite you to join them in celebrating the International Year of Light:

"Civilization would not exist without light—light from our sun and light from the focused and coherent lasers that have now become an important part of our daily lives; from scanning packages at supermarkets, to eye surgery, and to IT communications across oceans. The International Year of Light will surely raise awareness of these powerful discoveries and their present wide-ranging, light-based technologies, which are significant contributors to the world market. As importantly, the International Year of Light will inspire future discoveries and applications for one of the most important elements of our existence: light."

Light for the Future:
The science and technology of light are essential for the future development of humankind, and in the search of solutions to solve global problems in sustainability and healthcare through international cooperation. We hope that International Year of Light will increase global awareness of the central role of light in human activities through optics and photonics, and that the brightest young minds continue to be attracted to careers in this field.

Light-based Industries: Industries based on light are major economic drivers, and the many applications of light-based technologies have revolutionized and impacted society through medicine, communications, entertainment and culture.

Light-based technologies directly respond to the needs of humankind by providing access to information, promoting sustainable development, and increasing well-being and standard of living -- perfect examples include the inexpensive solar-powered solid-state lighting that has replaced toxic kerosene for indoor use in some developing regions, remote sensing from space that tracks crop health, major storms, and underground water sources, and non-invasive screening of infants for life-threatening breathing or digestive conditions.
