Hole in 1(am) - Golfers can Play All Night Thanks to LED Balls


With the clocks going forward and those long summer evenings just around the corner, golfers everywhere will be looking FORE-ward to playing long into the night.

But why end your round when the sun finally decides to go down?

Keen golfers can now play all night as well as all day - thanks to these amazing light-up LED golf balls.

They are the brainchild of U.S. suppliers Night Sports USA and light up in one of four colours when they are hit, staying alight for eight minutes after each shot.

They also produce light-up tees, fairway yardage markers and flags.

Experts at the company insist they play exactly like a standard golf ball except they float in water so can be retrieved.

A spokesperson for Night Sports USA said: “The balls provide the high performance aerodynamics, control, accuracy, feel and distance you expect from a professional quality ball.

“We developed night golf as a fun, innovative way of furthering existing player’s game - and also for a bit of fun. There are twice as many night time hours as there are day time which makes night time golf perfect.”

The balls, which can stay illuminated for up to 40 hours without recharging, are available online with a four-pack costing £18.

 

Scientists Develop LED That’s Thinner Than a Human Hair

Scientists in the US claim to have built what they describe as the “thinnest known” LED, which is smaller than the thickness of a human hair.

It’s believed that the minuscule bulb could be used in applications, small gadgets and mobile devices.

Scientists at the University of Washington (UW) said the LEDs are based on two-dimensional flexible semiconductors, making it possible to stack them and use them in much smaller and more diverse applications than present technology allows.

The ultra thin LEDs will also consume much less energy than the lamps currently being used.

Most consumer electronics devices use three-dimensional LEDs that are around 10 to 20 times thicker than this one.

“These are 10,000 times smaller than the thickness of a human hair,” said UW materials science and engineering graduate student Jason Ross.

“This is a huge leap of miniaturisation of technology, and because it’s a semiconductor, you can do almost everything with it that is possible with existing, three-dimensional silicon technologies.”

Xiaodong Xu is assistant professor of materials science and engineering at UW. He added:  “We are able to make the thinnest possible LEDs, only three atoms thick yet mechanically strong.

“Such thin and foldable LEDs are critical for future portable and integrated electronic devices.”

The scientists believe the technology could also open doors for using light as interconnects in nano-scale computer chips instead of standard devices that operate using the movement of electrons, or electricity.
