Limelight (also known as Drummond light or calcium light) [1] is a non-electric type of stage lighting that was once used in theatres and music halls. An intense illumination is created when a flame fed by oxygen and hydrogen is directed at a cylinder of quicklime ( calcium oxide ), [ 2 ] due to a combination of incandescence and ...
Leviton Manufacturing Company, Inc. is an American manufacturer of electrical wiring equipment in North America. The company produces electrical outlets including GFCI and USB charging devices , network infrastructure, lighting control systems , load centers and circuit breakers , EV charging stations, and utility submetering .
A low steady current can illustrate the gas spectrum in a gas-filled tube. A neon lamp is an example of a gas-discharge lamp, useful both for illumination and as a voltage regulator. A flashtube generates a short pulse of intense light useful for photography by sending a heavy current through a gas arc discharge.
Current Lighting Solutions, LLC (formerly Current, powered by GE and GE Current, a Daintree company), trading as Current, is a company that sells energy management systems. It is headquartered in Greenville, SC, U.S. The company appointed Steve Harris as its new Chief Executive Officer, succeeding interim CEO Bill Tolley on May 30, 2023.
15 kW xenon short-arc lamp used in IMAX projectors High-speed, slow-motion video of a xenon flashtube recorded at a speed of 44,025 frames per second.. A xenon arc lamp is a highly specialized type of gas discharge lamp, an electric light that produces light by passing electricity through ionized xenon gas at high pressure.
The company is the successor to both Arrow-Hart & Hegeman and Eagle Electric, both of which Cooper Industries had acquired. The Arrow-Hart brand is still used by Cooper Wiring Devices for some of their commercial products. Cooper Wiring's key competitors today include Hubbell, Leviton, Legrand and Lutron Electronics Company.
Current crowding is one of the factors limiting the efficiency of light-emitting diodes. Materials with low mobility of charge carriers (e.g., aluminium gallium indium phosphide (AlGaInP)) are especially prone to current crowding phenomena. It is the dominant loss mechanism in some LEDs, where the current densities, especially around the P-side ...
The Staebler–Wronski Effect (SWE) refers to light-induced metastable changes in the properties of hydrogenated amorphous silicon. The defect density of hydrogenated amorphous silicon (a-Si:H) increases with light exposure, causing an increase in the recombination current and reducing the efficiency of the conversion of sunlight into electricity.
