Whois & Analysis for usedlighting.com

Stage lighting is the craft of lighting as it applies to the production of theatre, 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.

An LED lamp is a light-emitting diode (LED) product which is assembled into a lamp (or light bulb) for use in lighting fixtures.

LED lamps have a lifespan and electrical efficiency which are several times greater than incandescent lamps, and are significantly more efficient than most fluorescent lamps, with some chips able to emit more than 300 lumens per watt (as claimed by Cree and some other LED manufacturers).

The LED lamp market is projected to grow by more than twelve-fold over the next decade, from $2 billion in the beginning of 2014 to $25 billion in 2023, a compound annual growth rate (CAGR) of 25%.

As of 2016, LEDs use only about 10% of the energy an incandescent lamp requires.

Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect.

Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight.

Daylighting (using windows, skylights, or light shelves) 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.

Intelligent lighting refers to stage lighting that has automated or mechanical abilities beyond those of traditional, stationary illumination.

Although the most advanced intelligent lights can produce extraordinarily complex effects, the intelligence lies with the programmer of the show rather than the instruments or the lighting operator.

For this reason, intelligent lighting is also known as automated lighting, moving lights or moving heads.

In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object".

A "two-force member" is a structural component where force is applied to only two points.

Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as nodes.
