Stage and show lighting Lighting is important in theatre and shows. Lighting allows us to see the performers. Lighting provides a tool for setting moods and tones of scenes on stage. Different type of performanced have different lighting needs. Here are some typical lighting situations: Dance - Back lighting Theatre plays - a somwhow realistic looking combination of different lights Straight Theatre - Light through a window Stage lighting is achieved by the use of a large number of powerful stage lights, or lanterns or luminaires.
There are a great variety of these, for different applications, or of different make or vintage. So there are many different types of lighting instruments used in any theatre. Each type of instrument plays an important role in the overall lighting scheme. The most common light types used in theatres are plane convex lights, freshnels, profiles, which are the generic classes of spotlights.
In addition to this floods are used for various applications. Also used are PAR cansbut these offer little control and are used more in rock lighting than in theatre. Most luminaires use at least one lens, which is a piece of glass with one or both sides curved for concentrating or dispersing the light beam; this produces a variation in the beam angle and the quality of the light produced.
Some luminaires utilise an attachment on the front of the unit called a barndoor. This consists of four movable metal flaps which are used to control the spill of light produced.
The lamp which generates the light inside light instrument is a glass or quartz envelope which contains a filament or electrodes surrounded by a gas. The most common lamp types are: If coloured or tinted light is required, as is usually the case, sheets of gel or colour held in special gel frames are placed in front of the lanterns.
The light color is controlled by color filters that are placed in front of the light bulb that created the white light. The filter passed through the needed wavelengths to produce the needed light color. In the early days of the electric filament lamp, gelatin color filters were used to color stage lighting fixtures.
Gelatin filters dissolved when wet, and could not withstand the high heat from the tungsten halogen lamp. Next filter technology was Cinemoid. Cinemoid used a colored acetate sheeting, with inherent self-extinguishing properties.
This base is then coated with specially prepared lacquers. The lacquer coating is applied to both sides of the film, is also tough and flexible and has a high resistance to water and heat. This kind of filters may scratch and the surface color may actually vaporize from the surface, through atmospheric contact.Community member duja found a convenient way to change the skin in version +.
