    en.wikipedia.org/wiki/Artificial_sunlight

    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 ...

    en.wikipedia.org/wiki/Heliodon

    HFT, Stuttgart University of Applied Sciences, Stuttgart uses a robotic heliodon at their Daylight Planning Lab. [19] The lab uses two elements in their daylight simulator – an artificial sky and artificial sun. [19] The artificial sun simulator consists of a halogen bulb with a parabolic reflector to replicate parallel sunlight.

  4. Dawn simulation - Wikipedia

    en.wikipedia.org/wiki/Dawn_simulation

    Dawn simulation is a technique that involves timing a light, often called a wake-up light, sunrise alarm clock, or natural light alarm clock, in the bedroom to come on gradually, over a period of 30 minutes to 2 hours, before awakening to simulate dawn.

  5. Artificial sky - Wikipedia

    en.wikipedia.org/wiki/Artificial_sky

    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.

    en.wikipedia.org/wiki/Solar_simulator

    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.

    en.wikipedia.org/wiki/Aquarium_lighting

    All in one fixtures require large fans to cool the bulbs and achieve maximum light efficiency. LED lighting is also becoming more common for not only lunar lighting but also to simulate daylight conditions, LEDs have a higher initial cost than other lighting sources but utilize much less energy. They are also dimmable.
