A complete lighting fixture unit consists of the light source or [[lamp (electrical component)|lamp]], the reflector for directing the light, an aperture (with or without a [[Lens (optics)|lens]]), the outer shell or housing for lamp alignment and protection, an [[Ballast (electrical)|electrical ballast]], if required, and connection to a power source. A wide variety of special light fixtures are created for use in the automotive industry, aerospace, marine and medicine. Light fixtures are classified by how the fixture is installed, the light function or lamp type. ==Fixture types== [[Image:Chandelier q.jpg|thumb|right|250px|A [[chandelier]] light fixture]] [[Image:Tiffany dragonfly lamp with pigeon sculptures.jpg|thumb|[[Tiffany lamp|Tiffany dragonfly desk lamp]] with pigeon sculptures]] * Free-standing or portable — table lamps, standard lamps and office task lights. Note: The use of "lamp" to describe light fixtures is different from its use to describe electrical components - see ''[[Lamp (electrical component)]]''. * [[Recessed light]] — the protective housing is concealed behind a ceiling or wall, leaving only the fixture itself exposed. The ceiling-mounted version is often called a "downlight". ** "Cans" with a variety of lamps — this term is jargon for inexpensive downlighting products that are recessed into the ceiling. The name comes from the shape of the housing. The term "pot lights" is often used in Canada and parts of the US. ** [[Troffer light]] — recessed fluorescent lights (the word comes from the combination of trough & coffer) * [[Surface-mounted]] light — the finished housing is exposed; not "flush" with surface ** [[Chandelier]] * [[Pendant light]] — suspended from the ceiling with a chain or pipe * [[Sconce (light fixture)|Sconce]] — provide up or down lights; can be used to illuminate artwork, architectural details; commonly used in hallways and/or as an alternative to overhead lighting. * [[Indirect lighting]] — light reflects off the ceiling for general illumination * [[Cove light]] — recessed into the ceiling in a long box against a wall * [[Track lighting]] fixture — individual fixtures (track "heads") can be positioned anywhere along the track, which provides electric power. * [[Under-cabinet light]] — mounted below kitchen wall cabinets * [[Outdoor lighting]] — used to illuminate walkways, parking lots, roadways, building exteriors, landscape and architectural details. ** Pole or [[stanchion]] mounted — for landscape, roadways, and parking lots ** [[Pathway lighting]] — typically mounted in the ground at low levels for illuminating walkways ** [[Bollards]] — A type of architectural outdoor lighting that is a short, upright ground-mounted unit typically used to provide cutoff type illumination for egress lighting, to light walkways, steps, or other pathways * [[High bay]]/[[Low bay]] lighting — typically used for general lighting for industrial buildings * [[Strip light]]s or [[industrial light]]s — often long lines of fluorescent lamps used in a warehouse or factory * [[Emergency lighting]] or [[Exit light]] — connected to a battery or to an electric circuit that has backup power if the main power fails * [[Balanced arm lamps|Balanced arm lamp]] is a spot light with an adjustable arm like [[Anglepoise lamp|anglepoise]] and [[Luxo L1]]. == Light fixture functions == [[Image:Solarlight.JPG|thumb|200px|right| A garden [[solar lamp]] is an example of landscape lighting]] <div style="-moz-column-count:3; column-count:3;"> * [[Accent light]] * [[Background light]] * [[Blacklight]] * [[Recessed lighting|Downlight]] * [[Emergency light]] * [[Flood light]] * Landscape or [[outdoor lighting]] * [[Nightlight]] * [[Safelight]] * [[Safety lamp]] * [[Sconce (light fixture)|Sconce]] * [[Searchlight]] * [[Security lighting]] * [[Solar lamp]] * [[Step light]] * [[Street light]] * [[Strobe light]] * [[Spotlight]] * [[Study lamp]] * Torch lamp or [[torchiere]] * [[Wallwasher]] </div> ==Lamp types== [[Image:Lightbulb.jpg|right|150px]] {{main|List of light sources}} *'''Fuel lamps''' :[[Betty lamp]], [[butter lamp]], [[carbide lamp]], [[gas lighting]], [[kerosene lamp]], [[oil lamp]], [[rush light]], [[torch]], [[candle]] *'''[[Arc lamp]]s''' :[[Safety lamp]]s: [[Davy lamp]] & [[Geordie lamp]], [[Xenon arc lamp]], [[Yablochkov candle]] * '''[[Incandescent light bulb|Incandescent lamp]]''' :[[Incandescent Lamp#Bulb shapes, sizes, and terms|A-lamp]], [[Incandescent Lamp#Bulb shapes, sizes, and terms|PAR Parabolic reflector lamp]] (PAR), [[Reflector lamp]] (R), [[Bulged reflector lamp]] (BR) ''(Refer to lamp bases)'' :*Obsolete types: [[Limelight]], [[Carbon button lamp]], [[Mazda (light bulb)]], [[Nernst glower]] :*Novelty: [[Blacklight]], [[Lava lamp]] :*Special purpose: [[Heat lamp]], [[Nernst lamp]], [[HQI]] *'''[[Incandescent light bulb#The halogen lamp|Halogen]]''' - special class of incandescent lamps *'''[[Gas discharge lamp]]''' and [[High-intensity discharge lamp|High-Intensity Discharge lamp]] (HID) :[[Mercury-vapor lamp]], [[Ceramic discharge metal halide lamp]], [[Metal-halide lamp|Metal-halide]], [[Sodium vapor lamp|Sodium vapor]] or "high pressure sodium", [[Hydrargyrum medium-arc iodide|HMI]] :*[[Neon sign]], [[Plasma lamp]] *''' Fluorescent''' :[[Fluorescent lamp|Linear fluorescent]], [[Compact fluorescent lamp|Compact Fluorescent Lamp]] (CFL) * [[Cold cathode]] * [[Fiber optics]] * [[Induction lamp]] * [[Light-emitting diode|Light-Emitting Diode]] (LED) ([[Solid State Lighting|Solid state lighting]]) *'''Nuclear:''' [[Self-powered lighting]] ==Light fixture controls== * [[Light switch]] * [[Dimmer]] * [[Motion detector|Occupancy sensor]] * [[Timer]] * [[Touch-sensitive lamp|Touch]] ==See also== * [[Architectural lighting design]] * [[History of street lighting in the United States]] * [[Lighting designer]] for the theater * [[List of light sources]] * [[Luminous efficacy]] * [[Study lamp]] {{Rhere}} * [[Timeline of lighting technology]] {{ArtificialLightSources}} [[Category:Electrical systems]] [[Category:Lighting]] [[Category:Architectural elements]] [[cs:Svítidlo]] [[da:Armatur]] [[de:Leuchte]] [[es:Lámpara]] [[fr:Luminaire]] [[he:גוף תאורה]] [[nl:Armatuur]] [[pl:Oprawa oświetleniowa]] [[ru:Светильник]] [[scn:Làmpara]] [[sv:Armatur]]
