The diffuse reflection principle of stage electric hoists

　　As is well known, the surface of the stage electric hoist is coated with special paint, which effectively avoids discomfort to the audience caused by reflected light during the stage performance. So, what is the principle behind the characteristics of the stage electric hoist?

　　First, let's understand two concepts: specular reflection and diffuse reflection. Specular reflection refers to the phenomenon where if the reflective surface is relatively smooth, when parallel incident light rays reach this reflective surface, they will still reflect in one direction in a parallel manner. This type of reflection belongs to specular reflection; Diffuse reflection refers to the phenomenon where light is irregularly reflected in various directions by a rough surface.

　　The reflected light on the mirror is very strong and can cause significant visual interference to us. For example, when the high beam of a car coming from behind hits the reflector of a car in front, it will reflect a dazzling light. If the light is diffusely reflected and transmitted to all directions, the light becomes much softer, and the stage electric hoist adopts this principle.

　　The surface of some stage electric hoists appears very smooth, but the reflected light is very soft. This is precisely because it uses diffuse reflective paint, which not only ensures that the stage electric hoists have sufficient texture, but also ensures the softness of the stage reflected light.

　　Why is the lifting equipment used for stage construction always the stage electric hoist

　　The stage electric hoist belongs to the specialized lifting equipment for stage construction work. Like traditional electric hoists, it controls the lifting operation through remote control. Many people do not understand this. Since the operation mode is the same, why can't ordinary electric hoists be used instead of stage electric hoists?

　　Firstly, we need to clarify that ordinary electric hoists can only be used for lifting and hoisting during construction work, and have no practical value after construction is completed. On the other hand, stage electric hoists are different, as they still need to be used to adjust and change the lighting position during the performance process. You may wonder, can ordinary electric hoists also do these tasks? This will involve another issue, which is the impact on the stage effect.

　　The stage electric hoist uses special materials, which will present a diffuse reflection effect on the lighting during the performance, without affecting the audience's vision. At the same time, the noise generated by the stage electric hoist during operation is extremely low, which will not have any impact on the audience's hearing. These characteristics cannot be replaced by ordinary electric hoists, so it is necessary to choose a stage electric hoist for stage construction.
