An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a filament that is heated until it glows. The filament is enclosed in a glass bulb that is either evacuated or filled with inert gas to protect the filament from oxidation. Electric current is supplied to the filament by terminals or wires ...
Like the incandescent soot in a luminous flame, the mantle is heated and then glows. The flame does not provide much light itself, and so a more heat-efficient non-luminous flame is preferred. Unlike simple soot, a mantle uses rare-earth elements to provide a bright white glow; the colour of the glow comes from the spectral lines of these ...
The carbon button lamp is a single-electrode incandescent lamp invented by Nikola Tesla in the 1890s. [1] A carbon button lamp contains a small carbon sphere positioned in the center of an evacuated glass bulb.
An incandescent gas mantle, gas mantle or Welsbach mantle is a device for generating incandescent bright white light when heated by a flame. The name refers to its original heat source in gas lights which illuminated the streets of Europe and North America in the late 19th century.
An artist's statement (or artist statement) is an artist's written description of their work. The brief text is for, and in support of, their own work to give the viewer understanding. As such it aims to inform, connect with an art context, and present the basis for the work; it is, therefore, didactic, descriptive, or reflective in nature.
Views of a liquid crystal display, both with electroluminescent backlight switched on (top) and switched off (bottom). Electroluminescence (EL) is an optical and electrical phenomenon, in which a material emits light in response to the passage of an electric current or to a strong electric field.
Since both phosphorescence (transition from T 1 to S 0) and the generation of T 1 from an excited singlet state (e.g., S 1) via intersystem crossing (ISC) are spin-forbidden processes, most organic materials exhibit insignificant phosphorescence as they mostly fail to populate the excited triplet state, and, even if T 1 is formed ...
Mark making is the interaction between the artist and the materials they are using. [1] It provides the viewer of the work with an image of what the artist had done to create the mark, reliving what the artist had done at the time. [1] Materiality is the choice of materials used and how it impacts the work of art and how the viewer perceives it ...
