Learning From Nature – Improving LEDs

This is NOT a religious rant so please bear with me.

FireflyTwo Jehovah’s Witnesses dropped by the other day and left after a short time, leaving me with copies of their two publications – Awake! and The Watchtower.

As I deposited them on the kitchen table I noticed on the back page of the February 2014 issue of Awake! a story entitled The Lantern of the Photuris Firefly.

Well naturally the word lantern caught my eye plus the fact that fireflies are prevalent in the Philippines where I am living right now.

Interesting story, and very interesting how scientists adapted it to modern day Light Emitting Diode (LED) technology which is used in your el-cheapo flashlights up to modern high-intensity LEDs for beacons and marker lamps of all sorts used in lighthouses and light beacons.

Especially take note of the fact:

. . . scientists coated LEDs with a corrugated surface similar to that of the firefly’s lantern. The result? The LEDs emitted up to 55 percent more light!

Instead of repeating the story below, please follow the link. It is a short and worthwhile read.
