The biggest geomagnetic storm in two decades, sparked by solar flares, caused dazzling lights displays in parts of Latin America overnight on Friday, including a rare appearance in Mexico. In ...
Long regarded as offering one of the best Christmas light displays in the nation, Branson's 1880's-style theme park Silver Dollar City will be decked out in a whopping 6.5 million lights for its ...
The Northern Lights hit their peak between 2 a.m. and 3 a.m. Saturday. However, more geomagnetic activity is heading Earth's way over the weekend from additional solar flares, possibly lasting ...
Main article: Light-emitting diode physics. In a light-emitting diode, the recombination of electrons and electron holes in a semiconductor produces light (be it infrared, visible or UV), a process called " electroluminescence ". The wavelength of the light depends on the energy band gap of the semiconductors used.
A LED is a long-lived light source, but certain mechanisms can cause slow loss of efficiency of the device or sudden failure. The wavelength of the light emitted is a function of the band gap of the semiconductor material used; materials such as gallium arsenide , and others , with various trace doping elements , are used to produce different ...
In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED. The voltage drop across an LED is approximately constant over a wide range of operating ...
The northern lights colored the Tri-Cities sky Friday night with a spectacular light show. The clear warm night drew thousands out into the darkness hoping to see the often elusive dancing display.
A dazzler is a non- lethal weapon which uses intense directed radiation to temporarily disorient its target with flash blindness. They can effectively deter further advances, regardless of language or cultural barriers, but can also be used for hailing and warning. [1] Targets can include electronic sensors as well as human vision.
Wales was treated to a breathtaking display overnight from the Northern Lights. Dozens of BBC Weather Watchers captured the aurora borealis on camera across the whole of Wales including Anglesey ...
Early patterns with unknown futures, such as the R-pentomino, led computer programmers to write programs to track the evolution of patterns in the Game of Life. Most of the early algorithms were similar: they represented the patterns as two-dimensional arrays in computer memory. Typically, two arrays are used: one to hold the current generation ...
