Scoop Light - Scoop lights or Scoops are circular fixtures that do not have any lenses. They have a reflector at the back of the fixture that directs the light out of the fixture. Since they do not have any sort o. Used Studio Color 575 M. f lens system they are cheaper than other fixtures. However, the downside of this makes it so that you can not focus the light at all (even PAR's allow for more control than. Used Studio Color 575 M. scoops).
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 Studio Color 575 M. 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. Ste. Used Studio Color 575 M. pper motors do not 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, mea
Kelvin - The kelvin (symbol: K) is the SI unit of temperature, and is one of the seven SI base units. It is defined by two facts: zero kelvins is absolute zero (when molecular motion stops), and one kelvin is . Used Studio Color 575 M. the fraction 1/273.16 of the thermodynamic temperature of the triple point of water. The Celsius temperature scale is now defined in terms of the kelvin, with 0 °C correspon. Used Studio Color 575 M. ding to 273.15 kelvins, approximately the freezing point of water under ordinary conditions.
The kelvin is named after the British physicist and engineer William Thomson, 1st Baron Kelvin; his barony was in turn na...
Lens - A lens is a device for either concentrating or diverging light, usually formed from a piece of shaped glass. Analogous devices used with other types of electromagnetic radiation are also called lense. Used Studio Color 575 M. s: for instance, a microwave lens can be made from paraffin wax.
The earliest records of lenses date to Ancient Greece, with Aristophanes' play The Clouds (424 . Used Studio Color 575 M. BC) mentioning a burning-glass (a convex lens used to focus the sun's rays to produce fire). The writings of Pliny the Elder (23-79) also show that burning-glasses were known to the Roman Empire, and mentions what is possibly t
DMX-512 - DMX512, often shortened to DMX (Digital MultipleX), is a communications protocol used mainly to control stage lighting.
Developed by the Engineering Commission of USITT, the standard star. Used Studio Color 575 M. ted in 1986, with subsequent revisions in 1990 leading to USITT DMX512/1990. ESTA took control of the standard in 1998 and began a revision process. The new standard, known .
