The theatrical world is a living organism, it is changing as rapidly as the surrounding reality, but there are things that are not subject to time. For example, the organization of the stage space, the unity of time and place of action, as well as some technical features like lighting and the arrangement of devices.
Era of living fire
Specific lighting of the stage has been used since the time of the ancient Greek and Roman theater, in those days oil torches were used, placed around the perimeter of the amphitheater. To create the color or a certain atmosphere of mystery, colored smoke was used, as well as a reduction in the number of torches.
In the Middle Ages, the stage began to be lit with candles, and later with gas lamps. Reflectors were used for both light sources: polished metal or mirror. With the advent of incandescent lamps in stage lighting, a new era has come.
Artists highlight various scenes and individual actors with light to give them greater expressiveness and stylistic orientation.
Incandescent lamps
Until the 30s of the last century, primitive electric lamps were used for stage lighting; they were installed point and peripherally. On average, up to 500 lamps were used in one performance, which were controlled by 350-500 circuit breakers. In the early 30s, the first special spotlight was invented for the stage based on an elliptical reflector, which became widely used in theaters to create special lighting effects during the performance. Using the light design of the scene, you can achieve the most realistic perception of the performance and give it greater naturalness.
Profile projectors on the slang are called "head", they are really large and round, are installed around the perimeter of the ramp. By the way, the ramp also has lighting, usually linear.
