Stage lighting design is an important part of event planning. Whether the processing of each light position and the stage design can form a perfect whole is one of the things that the executive team should care about most. Before explaining each lamp position in detail, it is necessary to explain the common issues:
1) Due to the various forms of the stage, the lighting position will change accordingly. But the ever-changing principle is to strive for the perfect unity of form and content on the premise of satisfying artistic functions. This article takes the traditional framed stage as the research object.
2) The actors are the main body of the performance. When the actors are active in the main performance area, their faces should be well illuminated. For lamp positions involving lighting in the performance area, the 'effective lighting range' does not refer to the ground range. Instead, it requires a level elevation of 1.7m from the stage surface (the height of the average human eye) as the lighting benchmark.
3) The stage depth function is divided according to the rules of performance: the first 1/3 is the main performance area, the middle 1/3 is the secondary performance area, and the last 1/3 is the scenic spot (background area). According to this rule, the stage lighting position also has a basic division of performance lighting: the external lighting position (surface light, outer light) mainly takes care of the lighting of the characters in the first 1/3 stage space; the proscenium lighting (the top light of the proscenium, the proscenium Side light) mainly takes care of the lighting of characters in the middle 1/3 of the stage space. This is just a general concept and commonly used spatial relationship, and does not mean that any performance uses space in this way. But as a stage lighting design should pay attention to this factor.
4) The design of each light position of the stage must ensure the installation space of a certain number of lamps according to the scale of the stage. The lamp has the space concept of horizontal rotation and vertical rotation. The design of the installation space of the lamp must consider two rotating factors (including the addition of color changers, cover and other accessories).
5) Due to the wide variety of lamps and lanterns, and continuous development. The installation space of each lamp position provides a flexible and adjustable structure as much as possible. If a fixed structure is adopted, the distance between the upper and lower poles of the hanging lamp space should not be less than 90cm, and the distance between left and right should not be less than 70cm. Light poles should be made of seamless steel pipes with a diameter of 50-60mm. Lamps and lanterns should be hung on round rods with lamp hooks and safety chains added.
6) In addition to the architectural form or performance form that needs to be exposed, the installation of each lamp position is generally concealed, so that the audience can not see the light source and operation as much as possible. Each lamp position is designed to provide good working conditions, convenient passages and safety facilities for the installation, maintenance and transportation of lighting equipment by lighting operators as much as possible.
