The PH Artichoke pendant is a Light fixture designed by Danish architect and designer Poul Henningsen.

Contents

It was manufactured by Louis Poulsen. It was created for the Langelinie Pavilion in Copenhagen in 1958.

Design

A chrome inner diffuser also assists in the proper even reflection of the light source. The light source can be an incandescent bulb (high powered halogen or xenon), fluorescent (with the ballast mounted in fixture canopy), or metal halide (canopy-mounted ballast). The metal halide sources are used in the largest of the Artichoke fixtures. For years, a number of companies have tried to replicate the Artichoke fixture, only a handful have made a replica that is at all geometrically and cosmetically similar.

The Poulsen Artichoke Pendant comes in copper, wet painted white or brushed stainless steel and in three different sizes. The leaves are laser-cut steel to produce shape lines reflective of modern design. The entire fixture is mounted by stainless steel aircraft cables to hold the unusually heavy weight of the light. A heavy duty UL Listed junction box is generally required to handle the weight of this pendant. The metal halide–sourced version utilizes a 220-277 volt AC power input, generally requiring a dedicated 20 A circuit and breaker.

Name

The English name is PH Artichoke ( artichoke ). [1] The original Danish name is PH Kogle ( conifer cone ) [2] This name is also used in Norway and Germany [3] /PH Kogle/PH Zapfen. [4]

A flashlight or electric torch, usually shortened to torch, is a portable hand-held electric lamp. Formerly, the light source typically was a miniature incandescent light bulb, but these have been displaced by light-emitting diodes (LEDs) since the early 2000s. A typical flashlight consists of the light source mounted in a reflector, a transparent cover to protect the light source and reflector, a battery, and a switch, all enclosed in a case.

<span class="mw-page-title-main">High-intensity discharge lamp</span> Type of electric lamp/bulb

High-intensity discharge lamps are a type of electrical gas-discharge lamp which produces light by means of an electric arc between tungsten electrodes housed inside a translucent or transparent fused quartz or fused alumina arc tube. This tube is filled with noble gas and often also contains suitable metal or metal salts. The noble gas enables the arc's initial strike. Once the arc is started, it heats and evaporates the metallic admixture. Its presence in the arc plasma greatly increases the intensity of visible light produced by the arc for a given power input, as the metals have many emission spectral lines in the visible part of the spectrum. High-intensity discharge lamps are a type of arc lamp.

A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce light. The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger soda lime or borosilicate glass bulb. The outer bulb may be clear or coated with a phosphor; in either case, the outer bulb provides thermal insulation, protection from the ultraviolet radiation the light produces, and a convenient mounting for the fused quartz arc tube.

<span class="mw-page-title-main">Metal-halide lamp</span> Type of lamp

A metal-halide lamp is an electrical lamp that produces light by an electric arc through a gaseous mixture of vaporized mercury and metal halides. It is a type of high-intensity discharge (HID) gas discharge lamp. Developed in the 1960s, they are similar to mercury vapor lamps, but contain additional metal halide compounds in the quartz arc tube, which improve the efficiency and color rendition of the light. The most common metal halide compound used is sodium iodide. Once the arc tube reaches its running temperature, the sodium dissociates from the iodine, adding orange and reds to the lamp's spectrum from the sodium D line as the metal ionizes. As a result, metal-halide lamps have high luminous efficacy of around 75–100 lumens per watt, which is about twice that of mercury vapor lights and 3 to 5 times that of incandescent lights and produce an intense white light. Lamp life is 6,000 to 15,000 hours. As one of the most efficient sources of high CRI white light, metal halides as of 2005 were the fastest growing segment of the lighting industry. They are used for wide area overhead lighting of commercial, industrial, and public places, such as parking lots, sports arenas, factories, and retail stores, as well as residential security lighting, automotive headlamps and indoor cannabis grow operations.

A light fixture, light fitting, or luminaire is an electrical lighting device containing one or more light sources, such as lamps, and all the accessory components required for its operation to provide illumination to the environment. All light fixtures have a fixture body and one or more lamps. The lamps may be in sockets for easy replacement—or, in the case of some LED fixtures, hard-wired in place.

<span class="mw-page-title-main">Grow light</span> Lighting to aid plant growth

A grow light is an electric light that can help plants grow. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated. Outdoor conditions are mimicked with varying colour temperatures and spectral outputs from the grow light, as well as varying the intensity of the lamps. Depending on the type of plant being cultivated, the stage of cultivation, and the photoperiod required by the plants, specific ranges of spectrum, luminous efficacy and color temperature are desirable for use with specific plants and time periods.

Black oxide or blackening is a conversion coating for ferrous materials, stainless steel, copper and copper based alloys, zinc, powdered metals, and silver solder. It is used to add mild corrosion resistance, for appearance, and to minimize light reflection. To achieve maximal corrosion resistance the black oxide must be impregnated with oil or wax. Dual target magnetron sputtering (DMS) is used for preparing black oxide coatings. One of its advantages over other coatings is its minimal buildup.
