Many of the installations of sulfur lamps were for testing purposes only, but there remain a few sites where the lamps are in use as the primary lighting source. Perhaps the most visible of these would be the glass atriums in the National Air and Space Museum.
Light pollution is the presence of any unwanted, inappropriate, or excessive artificial lighting. In a descriptive sense, the term light pollution refers to the effects of any poorly implemented lighting sources, during the day or night. Light pollution can be understood not only as a phenomenon resulting from a specific source or kind of pollution, but also as a contributor to the wider, collective impact of various sources of pollution.
Koninklijke Philips N.V., commonly shortened to Philips, is a Dutch multinational conglomerate corporation that was founded in Eindhoven in 1891. Since 1997, its world headquarters have been situated in Amsterdam, though the Benelux headquarters is still in Eindhoven. The company gained its royal honorary title in 1998.
An arc lamp or arc light is a lamp that produces light by an electric arc.
A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, to produce ultraviolet and make a phosphor coating in the lamp glow. Fluorescent lamps convert electrical energy into useful light much more efficiently than incandescent lamps, but are less efficient than most LED lamps. The typical luminous efficacy of fluorescent lamps is 50–100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output.
Wright-Patterson Air Force Base (WPAFB) is a United States Air Force base and census-designated place just east of Dayton, Ohio, in Greene and Montgomery counties. It includes both Wright and Patterson Fields, which were originally Wilbur Wright Field and Fairfield Aviation General Supply Depot. Patterson Field is approximately 16 kilometres (10 mi) northeast of Dayton; Wright Field is approximately 8.0 kilometres (5 mi) northeast of Dayton.
Lighting or illumination is the deliberate use of light to achieve practical or aesthetic effects. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants.
Gas lighting is the production of artificial light from combustion of a fuel gas such as methane, propane, butane, acetylene, ethylene, hydrogen, carbon monoxide, coal gas or natural gas. The light is produced either directly by the flame, generally by using special mixes of illuminating gas to increase brightness, or indirectly with other components such as the gas mantle or the limelight, with the gas primarily functioning to heat the mantle or the lime to incandescence.
A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent light bulb; some types fit into light fixtures designed for incandescent bulbs. The lamps use a tube that is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.
The sulfur lamp is a highly efficient full-spectrum electrodeless lighting system whose light is generated by sulfur plasma that has been excited by microwave radiation. They are a particular type of plasma lamp, and one of the most modern. The technology was developed in the early 1990s and appeared promising, but was not a commercial success by the late 1990s. Since 2005, lamps are again being manufactured for commercial use.
Selective yellow or non-spectral yellow is a colour for automotive lamps, particularly headlamps and other road-illumination lamps such as fog lamps. Under ECE regulations, headlamps were formerly permitted to be either white or selective yellow—in France, selective yellow was mandatory for all vehicles' road-illumination lamps until 1993.
The Swedish Meteorological and Hydrological Institute is a Swedish government agency and operates under the Ministry of Climate and Enterprise. SMHI has expertise within the areas of meteorology, hydrology and oceanography, and has extensive service and business operations within these areas.
Stockholm Central Station, is the main railway station in Stockholm, and largest railway station in Sweden in terms of passenger numbers and train traffic. It is located in the Norrmalm district of central Stockholm on Vasagatan, extending from Vattugatan in the south to Kungsbron in the north. The station opened on 18 July 1871. Since 2001, the station building has been owned and managed by Jernhusen, while the platforms and tracks are overseen by the Swedish Transport Administration. The station code for Stockholm Central is Cst.
Light tubes are structures that transmit or distribute natural or artificial light for the purpose of illumination and are examples of optical waveguides.
District cooling is the cooling equivalent of district heating. Working on broadly similar principles to district heating, district cooling delivers chilled water to buildings like offices and factories. In winter, the source for cooling can often be seawater, so it is a cheaper resource than electricity to run compressors for cooling. Alternatively, district cooling can be provided by a Heat Sharing Network which enables each building on the circuit to use a heat pump to redirect heat to an ambient ground temperature circuit.
Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems. For example, insulating a building allows it to use less heating and cooling energy while still maintaining a comfortable temperature. Another method is to remove energy subsidies that promote high energy consumption and inefficient energy use. Improved energy efficiency in buildings, industrial processes and transportation could reduce the world's energy needs in 2050 by one third.
Fluorescent lamp recycling is the recovery of the materials of a spent fluorescent lamp for the manufacture of new products.
An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical grid that provides power to homes and industries within an extended area. The electrical grid can be broadly divided into the generators that supply the power, the transmission system that carries the power from the generating centers to the load centers, and the distribution system that feeds the power to nearby homes and industries.
The AIA Tower, formerly the Philamlife Tower, is an office skyscraper located in Makati, Philippines. It is owned and developed by Philam Properties Corporation, the real estate arm of the Philippine American Life and General Insurance Company. Standing at 200 meters (660 ft), it is currently the 7th-tallest building in Makati, and is the 14th-tallest building in the country and Metro Manila as well. The building has 48 floors above ground, and 5 basement levels for parking. It is also the current headquarters of AIA Philippines since 2023, which was renamed to AIA Tower.
Plasma lamps are a type of electrodeless gas-discharge lamp energized by radio frequency (RF) power. They are distinct from the novelty plasma lamps that were popular in the 1980s.
Paul Housberg is an American glass artist recognized for his use of fused and kiln formed glass as an architectural medium. He currently resides in Jamestown, Rhode Island.
