Artificial sunlight is useful in treating and preventing seasonal affective disorder (also known as winter depression, which causes depression symptoms specifically in winter), [3] and delayed sleep phase syndrome, in which the circadian rhythm (the rhythmic alternation between daylight and nighttime behavior and bodily states) is disturbed and the person falls asleep much later than he or she ...
15 kW xenon short-arc lamp used in IMAX projectors High-speed, slow-motion video of a xenon flashtube recorded at a speed of 44,025 frames per second.. A xenon arc lamp is a highly specialized type of gas discharge lamp, an electric light that produces light by passing electricity through ionized xenon gas at high pressure.
Laboratory class AAA solar simulator. A solar simulator (also artificial sun or sunlight simulator) is a device that provides illumination approximating natural sunlight.The purpose of the solar simulator is to provide a controllable indoor test facility under laboratory conditions.
The artificial sky is a daylight simulation device that replicates the light coming from the sky dome. An architectural scale model or 1:1 full-scaled aircraft is placed under an artificial sky to predict daylight penetration within buildings or aircraft that subjects to different situations, complex geometries, or heavily obstructed windows.
This list contains natural objects up to apparent magnitude 3.5. All objects are listed by their visual magnitudes, and objects too close together to be distinguished are listed jointly.
The Solar Bottle Bulb, as it has also been called, [7] is installed in the roof of homes with the purpose of refracting sunlight in order to light up a room. The project's innovation lies in its utilization of cheap, durable and readily available materials to produce high quality natural lighting enabling the urban poor to have access to an ...
This is a list of lighting design software for use in analyzing photometrics, BIM (Building Information Modeling), and 3D modeling.The software is typically used by importing the structural design via CAD files.
Computer graphics lighting is the collection of techniques used to simulate light in computer graphics scenes. While lighting techniques offer flexibility in the level of detail and functionality available, they also operate at different levels of computational demand and complexity. Graphics artists can choose from a variety of light sources ...
