'Lion Lights': A bright solution with LEDs

Sometimes innovative technologies come from the wildest places.

Such was the case for Richard Turere, a teen-age Maasai boy from Kitengela, Kenya, who only wanted to protect his family's herd of cattle, goats and sheep from the lions who roamed the savannah near the border of the Nairobi National Park.

At the age of nine, Turere was given the responsibility of  looking after the family cattle. After two years of losing too many of the livestock to lions while the family was sleeping, and with little access to technical information, he found a photonics-based method to keep the predators at bay.

Turere explained at a recent TED conference how he had noticed that the lions were unafraid of the fires he built to keep them away. They learned to skirt around them and remain in the shadows, still able to hunt vulnerable animals.

However, the lions were afraid of moving lights. They wouldn’t come near the Turere family stockade if someone walked around with a flashlight at night. After a few weeks of contemplation and experimentation, he came up with a simple and low-cost system to protect his family's source of meat and milk.

Turere, 11 at the time, put together an automated lighting system with LED bulbs from broken flashlights and a car battery powered by a solar panel. His system of “Lion Lights” is designed to flash light intermittently into the dark night, tricking lions into thinking someone is walking around with a flashlight.

His solution has been so successful, according to SPIE Professional magazine, that several neighboring families have asked for Lion Lights. So far, 75 such systems have been installed around Kenya.

In addition, Turere's Lion Lights provided a solution that benefits the animals that inhabit Nairobi National Park, which has the world's largest density of lions, and the tourist economy built around the wildlife of Africa.

It's an inspiring story and a true example of photonics for a better world. (Watch Richard's TED talk to hear him tell the story.)

Cataract surgery: misnomer?

On left, the patient’s left eye has no cataract and all structures are visible. On right, retinal image from fundus camera confirms the presence of a cataract. (From Choi, Hjelmstad, Taibl, and Sayegh, SPIE Proc. 85671Y , 2013)   Article by guest blogger Roger S. Reiss , SPIE Fellow and recipient of the 2000 SPIE President's Award. Reiss was the original Ad Hoc Chair of SPIE Optomechanical Working Group. He manages the LinkedIn Group “ Photonic Engineering and Photonic Instruments .” The human eye and its interface with the human brain fit the definition of an "instrument system."   The human eye by itself is also an instrument by definition. After the invention of the microscope and the telescope, the human eye was the first and only detector for hundreds of years, only to be supplemented and in most cases supplanted by an electro-optical detector of various configurations. The evolution of the eye has been and still is a mystery.   In National Geogr...

Taking a Deep Dive into the World of Biophotonics

Gavrielle presents her research in Ven SPIE Student Member Gavrielle Untracht is pursuing her PhD at The University of Western Australia. She had the chance to participate in the 9th International Graduate Summer School in Biophotonics this past June on the island of Ven between Sweden and Denmark. At the school, sponsored by SPIE, invited experts from around the globe gave extended presentations on topics like tissue optics, strategies for cancer treatment using lasers, and entrepreneurship in photonics. Attendees also had the opportunity to present their current research projects, results, or ideas. Gavrielle shares her experiences of the summer school with this community in the following guest blog post. I recently returned from a week of great discussions and beautiful weather at the 9th Biophotonics Summer School on the Isle of Ven, Sweden. This experience, made possible (in part) by SPIE, was an invaluable opportunity for networking and a deep dive into the world of bi...

#FacesofPhotonics: Opto-mechanical Designer Deven Patel

DYNAMIC FORCE: Patel enjoys a rainy day at the Gufufoss waterfall in Iceland Salut!  Meet Deven Patel, a graduate student at Université Laval's Center for Optics, Photonics, and Lasers (COPL) in Quebec City who is also working as an opto-mechanical designer at Esterline Technologies Corporation. Over the past two years, Patel was instrumental in Laval’s exoplanet-imaging project  HiCIBaS , or High-Contrast Imaging Balloon System. He had two main jobs: designing a dynamic structure for the star-pointing system and front-end optics (telescope, etc.), and developing a passive-cooling thermal system for the back-end optics system. "Basically, I developed the mechanical solutions that were necessary for the other systems to function correctly and to perform the science of the mission," he explains. I CAN SEE CLEARLY NOW: HiCIBaS' telescope. Credit: Cédric Vallée The HiCIBaS project received quite a bit of media attention , and for good reason: "The proje...
