A prism transom bends light passing through the upper part of the window upwards. Prism lighting is the use of prisms to improve the distribution of light in a space. It is usually used to distribute daylight, and is a form of anidolic lighting.
In architecture, a transom is a transverse horizontal structural beam or bar, or a crosspiece separating a door from a window above it. This contrasts with a mullion, a vertical structural member. [1] Transom or transom window is also the customary U.S. word used for a transom light, the window over this crosspiece.
A transom window, or transom light, is a small window set above a larger window or a door, or, more specifically, above a transom, which is the horizontal beam above a door or window. (Yep, it's ...
The history of electric light is well documented, [11] and with the developments in lighting technology the profession of lighting developed alongside it. The development of high-efficiency, low-cost fluorescent lamps led to a reliance on electric light and a uniform blanket approach to lighting, but the energy crisis of the 1970s required more design consideration and reinvigorated the use of ...
Transom may refer to: Transom (architecture) , a bar of wood or stone across the top of a door or window, or the window above such a bar Transom (nautical) , that part of the stern of a vessel where the two sides of its hull meet
Door with sidelights. A sidelight or sidelite in a building is a window, usually with a vertical emphasis, that flanks a door or a larger window. [1] Sidelights are narrow, usually stationary and found immediately adjacent to doorways.
The human eye's response to light is non-linear, so a more even distribution of the same amount of light makes a room appear brighter. The source of all daylight is the Sun. The proportion of direct to diffuse light impacts the amount and quality of daylight. [1] "Direct sunlight" reaches a site without being scattered within Earth's atmosphere.
Light exerts physical pressure on objects in its path, a phenomenon which can be deduced by Maxwell's equations, but can be more easily explained by the particle nature of light: photons strike and transfer their momentum. Light pressure is equal to the power of the light beam divided by c, the speed of light.
