What are the design principles and technological requirements of stage lighting?

Lighting design is a very important part of stage exhibition. What problems should be considered in stage lighting design? What are the principles and technical requirements of stage lighting design? First of all, stage lighting design needs to consider how to set the type of scene lighting and the purpose of using lighting design. Secondly, the design principle of stage lighting is to ensure the accuracy and integrity of the stage lighting system, and the technological requirements include allowing the use of various lamps and other auxiliary equipment. About the specific knowledge of stage design, let's take a look at the article with me! 1. What problems should be considered in stage lighting design?

Stage lighting is one of the means of beautiful dance modeling. By using certain scientific and technological means, according to different plot development and different stage lighting mapping, it can play a role in highlighting the psychological changes of characters or rendering the atmosphere. Stage lighting is the crowning touch of a performance, so stage lighting design is particularly important, so what problems should be considered in stage lighting design?

1. How to set the type of scene lighting?

Scene lighting is usually divided into three types: natural light, artificial light or a combination of the two.

(1) Natural light is actually what we call sunlight. We need to pay attention to three issues when using sunlight: time, weather and brightness of light source. But the use of natural light is more difficult to operate, because many times you can only leave it to fate.

(2) Artificial light is the opposite of natural light. Artificial light is the most commonly used and universal of the three light sources. Lights, stoves or some luminous objects are recognized as artificial light as long as they can illuminate the surrounding environment. However, it should be noted that the use of artificial light needs to consider the source and quality of light.

(3) The last kind of lighting is the combination of natural light and artificial light. When shooting outdoors in bright light, photographers or lighting engineers will use mirrors or auxiliary lights to alleviate harsh shadows.

2, the purpose of using lighting design

Lighting helps to express emotions, or guide the audience's line of sight to the characteristic position, or make the audience form a special visual effect, which can provide greater depth for the scene and show a sense of hierarchy. Therefore, what color tone should be expressed in lighting design, and whether the designed lighting can better enhance the depth level.

3. Reference materials for scene design

When creating realistic scenes, we should get into the habit of drawing materials from actual photos and movies. Reference materials can provide you with better clues and let you know the specific object clearly.

4. How to use the key light

The main light is the most important light source in the scene. The key light is not necessarily just the light source, but it is the main light source of a photo. Similarly, a highlight light may not be fixed in one place like a point light source.

5. How to use fill light

Fill light is mostly used to fill the dark parts and shadow areas of the scene, and the light of fill light can provide depth of field and realism.

The more important supplementary light comes from natural diffuse reflection, which is usually called ambient light. This type of lighting is important in part because it improves the brightness of the whole scene, but the ambient light of most renderers is applied evenly to the whole scene.

6. How to use background light

Background light is usually used as "edge light" to separate the target object from the background by illuminating the edge of the object. It is best to put it in front of three-quarters of the key light and act on the edge of the object, resulting in a small reflective highlight area. This highlight will make the object increase the real credibility of the scene.

2. What are the design principles and technological requirements of stage lighting?

1, stage lighting design principles

(1) The design of stage lighting system is configured according to the rules and the special use requirements of stage art performances. The purpose of this paper is to design and configure all kinds of lighting technical equipment needed in the process of performing arts reproduction according to system engineering, so as to make the stage lighting system accurate and complete.

(2) Create a complete free space for stage lighting to meet all lighting requirements. In order to keep the system running, reserve and expand the space appropriately. Anti-interference ability and system security are important design indicators. In the system design, a new type of efficient and energy-saving electroluminescence is introduced, and DMX5 12 digital signal network technology is introduced in all aspects of the system design.

2. Process design requirements of stage lighting system

(1) The process design and equipment configuration of the system have the function of using a comprehensive cinema, which can rotate all kinds of lights into action programs of different types of cinemas in a short time.

(2) The system design can be quickly switched from one lighting scheme to another, and the switching time is completed within 2 hours.

(3) The system allows the use of various lamps and other auxiliary equipment.

(4) The system design has sufficient security and storage capacity. The whole system performs continuous diagnostic checks on the main console without interrupting the main power supply.
