The problem of lighting is very important. If you are outdoors, you should know the time of the activity in advance, consider the angle of sunlight, and avoid the backlight of the stage, which will interfere with the work of taking pictures under the stage. If the activity is indoors, consider the position of the light. First, it is convenient to connect electricity, and second, it is necessary to prevent wires from passing through the audience passage, causing potential safety hazards. The height of the stage, in the process of building, must adjust the height of the stage to the length and width suitable for the audience, so as to perfectly reflect the effect of the stage. In some large-scale activities, if the stage is too single, it will be dull, but reasonable design will make the stage feel layered and the effect will be the opposite. The ascending and descending channels of actors on the stage should also be considered reasonably to facilitate admission and exit. It is best not to set the passage as stairs, and the inclined passage will be better. Finally, the security issue. Before building the stage, we must fully understand the static load and dynamic load of the stage during the activity to ensure that the stage will not collapse.
