Stage lightingStage lighting is the craft of lighting as it applies to the production of theater, dance, opera, and other performance arts. Several different types of stage lighting instruments are used in this discipline. In addition to basic lighting, modern stage lighting can also include special effects, such as lasers and fog machines. People who work on stage lighting are commonly referred to as lighting technicians or lighting designers. The equipment used for stage lighting (e.g.
ÉclairageLéclairage est l'ensemble des moyens qui permettent à l'homme de doter son environnement des conditions de luminosité qu'il estime nécessaires à son activité ou son agrément. L'éclairage associe une source lumineuse (naturelle ou artificielle, fixe ou mobile) et d'éventuels dispositifs de type batteries, luminaires ou miroir/puits de Lumière. Les sources artificielles étaient le feu, des lampes à graisse, puis des lampes à huile, des torches, des bougies, les lampes à pétrole puis le gaz, puis des lampes électriques d’abord à incandescence (traditionnelle ou halogène) puis fluorescentes et électroluminescentes.
Lighting control consoleA lighting control console (also called a lightboard, lighting board, or lighting desk) is an electronic device used in theatrical lighting design to control multiple stage lights at once. They are used throughout the entertainment industry and are normally placed at the front of house (FOH) position or in a control booth. All lighting control consoles can control dimmers which control the intensity of the lights. Many modern consoles can control Intelligent lighting (lights that can move, change colors and gobo patterns), fog machines and hazers, and other special effects devices.
Landscape lightingLandscape lighting or garden lighting refers to the use of outdoor illumination of private gardens and public landscapes; for the enhancement and purposes of safety, nighttime aesthetics, accessibility, security, recreation and sports, and social and event uses. Light pollution exacerbated by excessive, misdirected or obtrusive use of light, but even carefully used light fundamentally alters natural conditions. As a major side-effect of urbanization, it is blamed for compromising health, disrupting ecosystems and spoiling aesthetic environments.
Projecteur asservithumb|Un projecteur asservi. Un projecteur asservi, communément appelé « moving light » ou « projecteur automatisé », «projecteur motorisé» est un projecteur possédant une régulation d'un ou plusieurs positionnements de ses accessoires (lyres, couteaux, roues de couleurs, de gobo, trichromie, dimmer, ...., ...). Il peut fréquemment être piloté à distance, réagir de façon automatique au son ou posséder des fonctions de tests automatisés.
Solid-state lightingSolid-state lighting (SSL) is a type of lighting that uses semiconductor light-emitting diodes (LEDs), organic light-emitting diodes (OLED), or polymer light-emitting diodes (PLED) as sources of illumination rather than electrical filaments, plasma (used in arc lamps such as fluorescent lamps), or gas. Solid state electroluminescence is used in SSL, as opposed to incandescent bulbs (which use thermal radiation) or fluorescent tubes. Compared to incandescent lighting, SSL creates visible light with reduced heat generation and less energy dissipation.
Éclairage de vélothumb|Un éclairage LED à pile. L'éclairage à vélo est l'ensemble des composants permettant à un cycliste de voir et d'être vu dans l'obscurité ou des conditions de faible visibilité. Ces composants peuvent être des phares ou des éléments réfléchissants. Dans la plupart des pays, l'éclairage est un équipement obligatoire. L'éclairage est un élément essentiel du cycliste urbain. Toutefois, il est aussi utile au cycliste sportif, pour les entraînements avec peu de visibilité, ou pour les courses de nuit.
Lighting control systemA lighting control system incorporates communication between various system inputs and outputs related to lighting control with the use of one or more central computing devices. Lighting control systems are widely used on both indoor and outdoor lighting of commercial, industrial, and residential spaces. Lighting control systems are sometimes referred to under the term smart lighting. Lighting control systems serve to provide the right amount of light where and when it is needed.
Logique quantiqueLa logique quantique est la base de raisonnements et conclusions en accord avec les postulats de la mécanique quantique. En particulier, les observables n'étant pas forcément commutatives, le théorème d'Heisenberg (cf. le principe d'incertitude), entraîne la notion d'intricats, notion purement quantique comme l'illustre celle de chat mort & vivant du célèbre paradoxe du chat de Schrödinger. John von Neumann a montré, en réfléchissant aux fondations de la mécanique quantique, que la logique d'Aristote (cf.
Quantum operationIn quantum mechanics, a quantum operation (also known as quantum dynamical map or quantum process) is a mathematical formalism used to describe a broad class of transformations that a quantum mechanical system can undergo. This was first discussed as a general stochastic transformation for a density matrix by George Sudarshan. The quantum operation formalism describes not only unitary time evolution or symmetry transformations of isolated systems, but also the effects of measurement and transient interactions with an environment.
