Green electroluminescence from a point contact on a crystal of SiC recreates Round's original experiment from 1907. Close-up of a 1 watt red power led. The first Light-Emitting Diode was created in 1927 by Russian inventor Oleg Losev, [1] and used silicon carbide as a semiconductor.
The Briton Narinder Singh Kapany investigated the propagation of light in fine glass fibers (optical fibers). The first wireless remote control for a television US-based Zenith consists of a better flashlight, with which one lights up in one of the four devices corners to turn the unit on or off, change the channel or mute the sound.
Beam of sun light inside the cavity of Rocca ill'Abissu at Fondachelli-Fantina, Sicily. The speed of light in vacuum is defined to be exactly 299 792 458 m/s (approximately 186,282 miles per second). The fixed value of the speed of light in SI units results from the fact that the metre is now defined in terms of the speed of light.
Tharon Myrene Musser (January 8, 1925 – April 19, 2009) [1] was an American lighting designer who worked on more than 150 Broadway productions.

In 1977, Kimble et al. demonstrated the first source of light which required a quantum description: a single atom that emitted one photon at a time. Another quantum state of light with certain advantages over any classical state, squeezed light, was soon proposed.
During his time at Yale, McCandless published some of the first books to lay out a method and approach to the art of lighting design. In his book A Method of Lighting the Stage (1932), McCandless details his method of lighting design which is based on the idea of breaking the stage down into uniform acting areas and manipulating light in terms of intensity, color, distribution, and control.
