A sconce or wall light is a decorative light fixture that is mounted to a wall. [1] The sconce is a very old form of fixture, historically used with candles and oil lamps.
They can provide general room lighting, and are common in hallways and corridors, but they may be mostly decorative. [1] A sconce may be a traditional torch, cresset, candle or gaslight, or a modern electric light source affixed in the same way.
Sconces can be placed on both the interior and exterior walls of buildings. [2] The light is usually, but not always, directed upwards and outwards, rather than down. In pre-modern usage, these usually held candles or gas flame, and torches respectively. Historically, candle sconces were often made of silver or brass from the 17th century, with porcelain and ormolu coming into use during the 18th century. The light of the candle flame was often intensified by a reflecting backplate. Using brackets, the candle or gas flame would be kept at safe distance from the wall and ceiling. [3]
Modern electric light fixture sconces are often used in hallways or corridors to provide both lighting and a point of interest in a long passage. Sconce height in a passageway is generally 3/4 of the distance up the wall as measured from the floor to the ceiling, and the distance between sconces on the wall is generally equal to the distance of the sconces from the floor, often alternating sides of the passageway.
Sconces are typically installed in pairs or other multiple units to provide balance. They can be used to frame doorways or line a hallway. Swing-arm sconces are often placed next to a bed to provide task lighting for reading.
A torch is a stick with combustible material at one end which can be used as a light source or to set something on fire. Torches have been used throughout history, and are still used in processions, symbolic and religious events, and in juggling entertainment. In some countries, notably the United Kingdom and Australia, "torch" in modern usage is also the term for a battery-operated portable light.
A candle is an ignitable wick embedded in wax, or another flammable solid substance such as tallow, that provides light, and in some cases, a fragrance. A candle can also provide heat or a method of keeping time.
Stage lighting is the craft of lighting as it applies to the production of theater, dance, opera, and other performance arts. Several different types of stage lighting instruments are used in this discipline. In addition to basic lighting, modern stage lighting can also include special effects, such as lasers and fog machines. People who work on stage lighting are commonly referred to as lighting technicians or lighting designers.
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.
A bathroom, restroom or washroom is a room, typically in a home or other residential building, that contains either a bathtub or a shower. The inclusion of a wash basin is common. In parts of the world e.g. India, a toilet is typically included in the bathroom; in others, the toilet is typically given a dedicated room separate from the one allocated for personal hygiene activities. In the United States, the word 'bathroom' is often used to refer to any room that contains a toilet, regardless of the inclusion of a bath or shower.
A lantern is an often portable source of lighting, typically featuring a protective enclosure for the light source – historically usually a candle, a wick in oil, or a thermoluminescent mesh, and often a battery-powered light in modern times – to make it easier to carry and hang up, and make it more reliable outdoors or in drafty interiors. Lanterns may also be used for signaling, as torches, or as general light-sources outdoors.
In the United States, Canada and the United Kingdom, grips are camera support equipment technicians in the filmmaking and video production industries. They constitute their own department on a film set and are directed by a key grip. Grips have two main functions: The first is to work closely with the camera department to provide camera support, especially if the camera is mounted to a dolly, crane, or in an unusual position, such as the top of a ladder. Some grips may specialize in operating camera dollies or camera cranes. The second function is to work closely with the electrical department to create lighting set-ups necessary for a shot under the direction of the director of photography.
Grips' responsibility is to build and maintain all the equipment that supports cameras. This equipment, which includes tripods, dollies, tracks, jibs, cranes, and static rigs, is constructed of delicate yet heavy duty parts requiring a high level of experience to operate and move. Every scene in a feature film is shot using one or more cameras, each mounted on highly complex, extremely expensive, heavy duty equipment. Grips assemble this equipment according to meticulous specifications and push, pull, mount or hang it from a variety of settings. The equipment can be as basic as a tripod standing on a studio floor, to hazardous operations such as mounting a camera on a 100 ft crane, or hanging it from a helicopter swooping above a mountain range.
Good Grips perform a crucial role in ensuring that the artifice of film is maintained, and that camera moves are as seamless as possible. Grips are usually requested by the DoP or the camera operator. Although the work is physically demanding and the hours are long, the work can be very rewarding. Many Grips work on both commercials and features.
A chandelier ( is an ornamental light fixture with multiple lights, typically with spreading branched supports, designed to hang down from the ceiling. Chandeliers are often ornate, and they were originally designed to hold candles, but now incandescent light bulbs are commonly used, and fluorescent lamps and LEDs may also be used in some modern designs.
A ceiling fan is a fan mounted on the ceiling of a room or space, usually electrically powered, that uses hub-mounted rotating blades to circulate air. They cool people effectively by increasing air speed. Fans do not reduce air temperature or relative humidity, unlike air-conditioning equipment but create a cooling effect by helping to evaporate sweat and increase heat exchange via convection. Fans add a small amount of heat to the room mainly due to waste heat from the motor, and partially due to friction. Fans use significantly less power than air conditioning as cooling air is thermodynamically expensive. In the winter, fans move warmer air, which naturally rises, back down to occupants. This can affect both thermostat readings and occupants' comfort, thereby improving the energy efficiency of climate control. Many ceiling fan units also double as light fixtures, eliminating the need for separate overhead lights in a room.
A nightlight is a small light fixture, usually electrical, placed for comfort or convenience in dark areas or areas that may become dark at certain times, such as at night or during an emergency. Small long-burning candles serving a similar function are referred to as "tealights".
An emergency light is a battery-backed lighting device that switches on automatically when a building experiences a power outage.
Architectural lighting design is a field of work or study that is concerned with the design of lighting systems within the built environment, both interior and exterior. It can include manipulation and design of both daylight and electric light or both, to serve human needs.
A catwalk is an elevated service platform from which many of the technical functions of a theater, such as lighting and sound, may be manipulated.
A girandole is an ornamental branched candle holder consisting of several lights that may be on a stand or mounted on the wall, either by itself or attached to a mirror. Girandole has been used to describe a variety of different objects and designs; the early girandoles were candelabras decorated with crystals looking like a chandelier on a stand, and at one time it was also used to describe all candelabras and chandeliers, with or without crystals. The girandole first appeared in France in the mid-17th century as a luxurious appliance for lighting, and large wall-mounted girandoles that may incorporate a mirror became fashionable in England in the second half of the 18th century. A form of girandole backed with a round convex mirror was also popular in the United States in the early 19th century.
A lampshade is a fixture that envelops the lightbulb on a lamp to diffuse the light it emits. Lampshades can be made out of a large variety of materials like paper, glass, fabric or stone. Oftentimes conical or cylindrical in shape, lampshades can be found on floor, desk, tabletop, or suspended lamps. The term can also apply to the glass hung around many designs of ceiling lamp. Beyond its practical purpose, significant emphasis is also usually given to decorative and aesthetic features. A lamp shade also serves to "shade" human eyes from the direct glare of the light bulbs used to illuminate the lamp. Some lamp shades are also lined with a hard-backed opaque lining, often white or gold, to reflect as much light as possible through the top and bottom of the shade while blocking light from emitting through the walls of the shade itself. In other cases, the shade material is deliberately decorative so that upon illumination it may emphasize a display of color and light emitting through the shade surface itself.
A light fixture, light fitting, lamp, or luminaire is an electrical device containing an electrical component called a lamp that provides illumination. 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.
Landscape lighting or garden lighting refers to the use of outdoor illumination of private gardens and public landscapes; for the enhancement and purposes of safety, nighttime aesthetics, accessibility, security, recreation and sports, and social and event uses.
A tealight is a candle in a thin metal or plastic cup so that the candle can liquefy completely while lit. They are typically small, circular, usually wider than their height, and inexpensive. Tealights derive their name from their use in teapot warmers, but are also used as food warmers in general, e.g. fondue.
Often task lighting refers to increasing illuminance to better accomplish a specific activity. However, the illuminance level is not the only factor governing visibility. Contrast is also important, and a poorly positioned light source may cause contrast reduction, resulting in loss of visibility. The most important purpose of task lighting in the office is not increasing illuminance, but improving contrast. General lighting can be reduced because task lighting provides focused light where needed.
A yard light or garden lantern is a free standing exterior light fixture in gardens and landscaped settings. They are usually illuminated by electricity, but occasionally natural gas, and are usually placed near an outdoor path or driveway to provide visibility in dark areas or areas that become dark at certain times. A solar lamp is operated by batteries charged by solar panels during the day.
