- Lighting consoles are electronic devices used in lighting design to control multiple lighting and staging devices. They can generally control dimmers and many modern consoles can also control automate. Used . d lighting, fog machines, hazers, and other special effects devices. Lighting consoles communicate with the devices in the lighting system with an electronic control protocol, the most common. Used . of which is DMX-512.
- A type of profile spot with two lenses allowing the adjustment of both the size of the beam and whether it is a hard or soft focus. This adjustment of focal length makes for an instrument with many us. Used . es around the stage. The flexibility is also vital when working with gobos. Also known (in the US) as a Zoom Ellipsoidal.. Used . ...Zoom Lens
- A mechanical assembly of lens elements with the capability to vary its focal length allowing for a closer or farther view of a subject, without changing perspective. Zoom lenses are often described b. Used . y the ratio of their focal lengths from longest to shortest. A 100mm to 400mm zoom may be described as a 4:1 or 4× zoom.
. Used . ...Stepper Motor
- A stepper motor is a type of electric motor that is used when something has to be positioned very precisely or rotated by an exact angle.
In a stepper motor, an internal rotor containing. Used . permanent magnets is controlled by a set of stationary electromagnets that are switched electronically. Hence, it is a cross between a DC electric motor and a solenoid. Stepper motors do not. Used . use brushes and commutators.
Stepper motors have a fixed number of magnetic poles that determine the number of steps per revolution. Most common stepper motors have 200 full steps/revolution, meaLimelight
- An early type of stage light in which an intense illumination is created when an oxyhydrogen flame is directed at a cylinder of lime, also called calcium oxide, which can be raised to white incandesce. Used . nce heat without melting to producing brilliant illumination. The limelight effect was discovered early in the nineteenth century by Goldsworthy Gurney. A Scottish engineer, Thomas Drummond. Used . , realized that the light would be useful for surveying and built a working version in 1826. Therefore, the light is sometimes known as the Drummond Light. The Limelights first theatrical use was in 1837 at ...
