Worklight
In theater, a worklight is a high-intensity light fixture which is used to illuminate the stage for the benefit of technicians. Technicians use these lights, rather than the stage lights for a number of reasons. Firstly, it takes much less technical knowledge to turn on worklights, so even people with no knowledge of electrics can turn them on. Secondly, regardless of the lights hung for the specific show, they provide fairly consistent and complete lighting. Finally, and most importantly, they are designed to be cheap and easy to re-lamp, in contrast to theatrical fixtures, which have expensive lamps and would burn through color gels if used to illuminate stage work. Worklights are not designed to light the stage in an aesthetically pleasing way, but rather to be efficient in terms of space and heat; however, they may occasionally be used to emphasize plot elements during a show. They are generally near-white. Worklights are usually placed on catwalks and battens, or can be pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scoop (theater)
In stage lighting, an ellipsoidal reflector floodlight (sometimes known by the acronym ERF which is often pronounced "erf"), better known as a scoop, is a large, simple lighting fixture with a dome-like reflector, large high-wattage lamp and no lens. It consists almost entirely of a lamp in the center of a big curved metal (or plastic lined with reflective foil) dome that acts as a reflector. The result is a wide, soft-edged pool of light good for general lighting. However, since scoop lights do not have a mechanism for cutting down the size of their beam, they are rarely used for more specific lighting needs. Many theaters use scoop lights for worklights, rehearsals, non-performance times, and certain performance times. Scoops can be used to mimic the effect of a striplight to illuminate a cyclorama. They are easy to set up and take down, are relatively inexpensive, typically have long lamp life. When used as worklights, scoop lights frequently don't require the use of the lig ...

Running Lights (theater)
In theater, running lights are any lights that the audience does not see, but are on during a performance. They are different from worklights which are not used during a show. One type of running light is the lights set in wings or crossovers for actors and technicians to find their way in the (mostly) dark. These are usually rope lights or traditional fixtures with a colored lamp or colored gel over them. Booth staff will also use running lights to illuminate control boards or scripts. One brand marketed for this specific purpose is LittLite. Cue light A theatrical cue is the trigger for an action to be carried out at a specific time. It is generally associated with theatre and the film industry. They can be necessary for a lighting change or effect, a sound effect, or some sort of stage or set m ...s are distinct from running lights. Stage lighting {{Stagecraft-stub ...

Light Fixture
A light fixture (US English), light fitting (UK English), or luminaire is an electrical device containing an electric 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. Fixtures may also have a switch to control the light, either attached to the lamp body or attached to the power cable. Permanent light fixtures, such as dining room chandeliers, may have no switch on the fixture itself, but rely on a wall switch. Fixtures require an electrical connection to a power source, typically AC mains power, but some run on battery power for camping or emergency lights. Permanent lighting fixtures are directly wired. Movable lamps have a plug and cord that plugs into a wall socket. Light fixtures may also have other features, such as reflectors for directing the light, an aperture (with or without a lens), an outer shell or housing f ...

Theatrical Technician
A theatrical technician (also known as a tech, technician, theatre tech, theatre technician, or techie) is a person who operates technical equipment and systems in the performing arts and entertainment industry. In contrast to performers, this broad category contains all "unseen" theatrical personnel who practice stagecraft and are responsible for the logistic and production-related aspects of a performance including designers, operators, and supervisors. Typical positions Theatrical responsibilities taken by technicians include: * Set construction and theatrical carpentry * Sound system configuration and operation * Lighting design and light board operation, Followspot operation, hanging and maintenance of stage lighting instruments as well as various other electrical jobs * Flying of scenery and occasionally even actors by fly men * Rigging of moveable and stationary set pieces by riggers * Stage management * Costume and prop management * Operation of Special effects ...

Catwalk (theater)
{{Unreferenced, date=June 2009 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. Function Catwalks are used to suspend lighting instruments and microphones directed at the stage. The catwalks provide easy access for theater personnel to perform common tasks. For example, lights may need to be accessed for maintenance, position adjustment, or addition and removal of gels and gobos. Placement Typically, catwalks are located in positions hidden from audience view or directly above an audience, and are considered "behind-the-scenes". For example, many proscenium theaters have a series of two or more catwalks running parallel to the proscenium arch above a false ceiling. Stairs or a ladder up to the catwalks is usually located somewhere backstage. In modern theatres, many architects design catwalks into the "look" of the theatre. In black box theatres, catwalks and pipe grids may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batten (theater)
In theaters, a batten (also known as a ''bar'' or ''pipe'') is a long metal pipe suspended above the stage or audience from which lighting fixtures, theatrical scenery, and theater drapes and stage curtains may be hung. Battens that are located above a stage can usually be lowered to the stage (flown in) or raised into a fly tower above the stage (flown out) by a fly system. Types Electric An ''electric'' is a batten that incorporates electrical cables above the pipe, often enclosed in a raceway. It typically has power cables for lights and DMX512 data cable for lighting control, and may also have audio cables for microphones. The cables emerge from one end of the batten and continue through a snake to dimmers, control boards, or patchbays. All cable plugs have identifying numbers printed on them so that they can be easily referenced by the lighting control system. Loaded electrics are among the heaviest types of battens, often weighing more than a thousand pounds. Electrics w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theatre
Theatre or theater is a collaborative form of performing art that uses live performers, usually actors or actresses, to present the experience of a real or imagined event before a live audience in a specific place, often a stage. The performers may communicate this experience to the audience through combinations of gesture, speech, song, music, and dance. Elements of art, such as painted scenery and stagecraft such as lighting are used to enhance the physicality, presence and immediacy of the experience. The specific place of the performance is also named by the word "theatre" as derived from the Ancient Greek θέατρον (théatron, "a place for viewing"), itself from θεάομαι (theáomai, "to see", "to watch", "to observe"). Modern Western theatre comes, in large measure, from the theatre of ancient Greece, from which it borrows technical terminology, classification into genres, and many of its themes, stock characters, and plot elements.

Fluorescent Lamp
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, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow. A fluorescent lamp converts electrical energy into useful light much more efficiently than an incandescent lamp. The typical luminous efficacy of fluorescent lighting systems is 50–100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output. For comparison, the luminous efficacy of an incandescent bulb may only be 16 lumens per watt. Fluorescent lamp fixtures are more costly than incandescent lamps because, among other things, they require a ballast to regulate current through the lamp, but the initial cost is offset by a much lower running cost. Compact fluorescent lamps are now available in the same popular sizes as incand ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LED Lamp
An LED lamp or LED light bulb is an electric light that produces light using light-emitting diodes (LEDs). LED lamps are significantly more energy-efficient than equivalent incandescent lamps and can be significantly more efficient than most fluorescent lamps. The most efficient commercially available LED lamps have efficiencies of 200 lumen per watt (Lm/W). Commercial LED lamps have a lifespan many times longer than incandescent lamps. LED lamps require an electronic LED driver circuit to operate from mains power lines, and losses from this circuit means that the efficiency of the lamp is lower than the efficiency of the LED chips it uses. The driver circuit may require special features to be compatible with lamp dimmers intended for use on incandescent lamps. Generally the current waveform contains some amount of distortion, depending on the luminaires’ technology. The LED lamp market is projected to grow from US$75.8 billion in 2020 and increasing to US$160 billion in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Fixtures
Light or visible light is electromagnetic radiation that can be perceived by the human eye. Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). In physics, the term "light" may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light. The primary properties of light are intensity, propagation direction, frequency or wavelength spectrum and polarization. Its speed in a vacuum, 299 792 458 metres a second (m/s), is one of the fundamental constants of nature. Like all types of electromagnetic radiation, visible light propagates by massless elementary particles called photons that represents the quanta of electromagnetic field, and can be analyzed as both waves and particl ...
