Hundreds of Drones Light Up the Night Sky

Hundreds of Drones Light Up the Night Sky

Drones can do everything, even put on a fireworks show. In Germany, 500 drones equipped with LEDs were launched into the sky. It was Intel’s idea. It broke the Guinness World Record for the most unmanned aerial vehicles in the air at the same time. There were hundreds of blinking lights in the night sky and it may have fooled everyone into thinking it was a real fireworks show, but since there weren’t any exploding noises, the show could have been mistaken for something else.

The quadcopters are made of form and plastic, and they weigh 0.5 pounds. The LEDs produce more than 4 billion color combinations. The drones are able to fly in formation and follow a pre-programmed routine.

LEDs are interesting. Here’s more info on this type of light source:

A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode, which emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor.

An LED is often small in area (less than 1 mm2) and integrated optical components may be used to shape its radiation pattern.

Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were also of low intensity, and limited to red. Modern LEDs are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.
