2. Skylight - Wikipedia

   en.wikipedia.org/wiki/Skylight

   The dome shape allows for shedding of water and burning embers. Plastics used in skylights are UV stabilized and may feature other advances to improve thermal properties. Lack of accepted standards for measuring light transmittance is a disadvantage for comparing and choosing skylights with plastic glazing.

3. Poly(methyl methacrylate) - Wikipedia

   en.wikipedia.org/wiki/Poly(methyl_methacrylate)

   Laser cut acrylic panels have been used to redirect sunlight into a light pipe or tubular skylight and, from there, to spread it into a room. [33] Their developers Veronica Garcia Hansen, Ken Yeang , and Ian Edmonds were awarded the Far East Economic Review Innovation Award in bronze for this technology in 2003.

4. 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.

   Total external reflection, hollow light tube Total internal reflection, block of acrylic. Light tubes (also known as solar pipes, tubular skylights or sun tunnels [1]) are structures that transmit or distribute natural or artificial light for the purpose of illumination and are examples of optical waveguides.

7. Daylighting (architecture) - Wikipedia

   en.wikipedia.org/wiki/Daylighting_(architecture)

   Skylights are widely used in daylighting design in residential and commercial buildings, mainly because they are the most effective source of daylight on a unit area basis. An alternative to a skylight is a roof lantern. A roof lantern is a daylighting cupola that sits above a roof, as opposed to a skylight which is fitted into a roof's ...
