Alternating Current - An alternating current (AC) is an electrical current where the magnitude and direction of the current varies cyclically, as opposed to direct current, where the direction of the current stays constan. Used . t. The usual waveform of an AC power circuit is a sine wave, as this results in the most efficient transmission of energy. However in certain applications different waveforms are used, such a. Used . s triangular or square waves.
Used generically, AC refers to the form in which electricity is delivered to businesses and residences. However, audio and radio signals carried on electrical wire ar
Arc Lamp - An arc lamp is a device that produces light by the sparking (or arcing, from voltaic arc or electric arc) of a high current between two carbon rod electrodes. The rods are touched and then slowly draw. Used . n apart; as the rods separate the current is "struck" and arcs across the gap in a bright, ionized path. The arc produces a temperature of several thousand degrees, and the tips of the carbon. Used . rods are heated to incandescence, creating light. The rods are slowly vaporized during the process and need to be regularly adjusted to maintain the arc. The concept was first demonstrated by Sir Humphry Davy...
Moving Lights - Moving lights or intelligent fixtures were originally implemented in 1972, but the first computer-controlled stage lighting fixtures began to gain widespread acceptance in the concert industry in the . Used . early 1980's. As the digital age progressed, the cost of these fixtures was reduced and they slowly started being used in more 'traditional' theatrical environments. Intelligent fixtures are . Used . currently used in almost all major theatrical productions.
Usually relying on compact arc lamps as a light source, these fixtures generally use stepper motors connected to varying internal devices...
Used Lasers
One of the many applications of lasers is in the entertainment industry. The reason for this is that lasers can make an extremely visible narrow beam of light which can be used with optical scanning to produce patterns or images on the walls, ceilings or other surfaces. Using mirrors, light from lasers can also be bounced to produce special effects or to enhance special effects smoke, fog or haze. The “laser tunnel effect” can be created using a planar or conical moving beam of laser light aimed through atmospheric smoke or fog.
A laser lighting display or lasers light show may involve projecting laser beams set to music or as stage lighting effects for a concert or other musical performance. Use of lasers in these applications is not a new concept. Back in the 70s, live performances by artists like Pink Floyd have already used laser light to enhance the concert experience.
Laser light shows can be customized for stage acts, theater, discos, dances, parties and similar events using programmable, animated lasers. They are available in a variety of colors and output powers. Lasers can produce rotating, bounce, size, color, slowdraw, stretch, rolling and other effects. Using software, images and text can also be displayed as part of a laser light display.
In the United States, operators of lasers apply beamstops and procedures as safety precautions for the audience. This is in compliance with the safety regulations governing the use of lasers in any product.
