A General Electric NE-34 glow lamp, manufactured circa 1930. Neon was discovered in 1898 by William Ramsay and Morris Travers.The characteristic, brilliant red color that is emitted by gaseous neon when excited electrically was noted immediately; Travers later wrote, "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget."
A 230-volt LED filament light bulb, with a B22 base. The filaments are visible as the four yellow vertical lines. A LED filament light bulb is a LED lamp which is designed to resemble a traditional incandescent light bulb with visible filaments for aesthetic and light distribution purposes, but with the high efficiency of light-emitting diodes (LEDs).
The material covering was used to prevent the flame in the lantern from being extinguished by wind, while still retaining its use as a light source. Papermaking technology originated from China from at least AD 105 during the Eastern Han dynasty , [ 2 ] [ 3 ] but it is unknown exactly when paper became used for lanterns.
A chandelier (/ ˌ ʃ æ n d ə ˈ l ɪər /) is an ornamental lighting device, typically with spreading branched supports for multiple lights, designed to be hung from the ceiling. [1] [2] Chandeliers are often ornate, and they were originally designed to hold candles, but now incandescent light bulbs are commonly used, [3] as well as ...
Luminaria is a term used in different parts of the world to describe various types of holiday lights, usually displayed during Christmas. In English, the term most commonly refers to a specific type of simple paper lantern made by placing a votive candle in some sand inside a paper bag. [1]
When lit, the flame heats the air inside the lantern, thus lowering its density and causing the lantern to rise into the air. The sky lantern is only airborne for as long as the flame stays alight, after which the lantern sinks back to the ground. In China, Taiwan and Thailand, sky lanterns are traditionally made from oiled rice paper on a ...
Early electrical nightlights used small incandescent lamps or small neon lamps to provide light, and were much safer than small candles using an open flame. The neon versions consumed very little energy and had a long life, but had a tendency to flicker on and off (reminiscent of a candle), which some users liked and others found annoying.
Flameless candles display flickering light, simulating real flames. As a decorative element, the design of a flameless candle is relatively versatile. The body or "housing" of the device is commonly cylindrical, containing a battery pack and an often flame-shaped LED lamp atop the candle. Many manufactures use LED lights with a sporadic ...
