1. Analysis of the particularity of the stage environment
As a complex system that integrates artistic expression and technical support, the particularity of the stage environment has a profound impact on the selection of stage equipment, the presentation of performance effects, and the experience of actors and audiences:
1). Variable climate conditions
1.1). The impact of indoor and outdoor temperature difference and humidity changes on electronic equipment:
The stage environment often needs to be converted between different indoor and outdoor venues.
Changes in temperature and humidity pose a severe challenge to electronic equipment. Excessive temperature differences may cause stress in the internal components of electronic equipment due to thermal expansion and contraction, which in turn affects its physical structure and electrical performance stability.
Excessive humidity may cause moisture inside the electronic equipment, leading to circuit short circuits, component corrosion, and other problems, while too low humidity may cause electrostatic discharge and damage sensitive components of electronic equipment.
Therefore, stage equipment must have good temperature and humidity adaptability or take additional temperature and humidity control measures, such as installing temperature and humidity adjustment equipment, using moisture-proof materials, etc., to ensure the normal operation of the equipment.
1.2). Waterproof and moisture-proof requirements in bad weather such as rainy days and foggy days:
In outdoor stage performances, bad weather, such as rainy days and foggy days, are common challenges. Rainwater may directly penetrate into the stage equipment, causing serious consequences such as circuit short circuits and component damage.
Foggy days may increase the humidity of stage equipment and accelerate the corrosion and aging process of equipment. Therefore, in bad weather, strict waterproof and moisture-proof measures must be taken.
For example, protective materials such as waterproof covers and waterproof cloth should be used to wrap the equipment to ensure that it can remain dry and stable in bad weather.
2). Physical shock and vibration
2.1). Accidental collision during stage construction and dismantling:
The stage construction and dismantling process is a complex and tedious process involving the collaboration of a large number of equipment and personnel.
In this process, the equipment may be collided due to improper operation or unexpected circumstances, resulting in damage or performance degradation.
Therefore, during the installation and disassembly process, the operating procedures must be strictly followed, and the equipment must be handled carefully to avoid unnecessary collision and damage to the equipment.
2.2). Possible contact between props or personnel during the performance:
During the stage performance, props and actors are indispensable elements. However, the movement of props and the performance of actors may come into contact with stage equipment, such as sound and lighting.
Such contact may cause equipment damage, performance degradation, or affect the performance effect. Therefore, when laying out the stage and installing the equipment, the range of activities of props and actors must be fully considered to ensure that there is a sufficiently safe distance between the equipment and props and actors to avoid unnecessary contact and collision.
3). Dust and pollution
3.1). Particle pollution generated by stage special effects (such as smoke and foam):
Stage special effects are an important means to enhance the performance effect and audience experience.
However, special effects such as smoke and foam may generate a large number of particles, which may adhere to the stage equipment and affect its surface finish and performance. Long-term accumulation may also cause problems such as internal blockage and poor heat dissipation of the equipment.
Therefore, stage equipment must be cleaned and maintained regularly to ensure that its surface is clean and dust-free, and the interior is unobstructed and unblocked.
3.2). Dust raised in the audience area:
The audience area is an indispensable part of stage performances. However, the activities of the audience may raise a lot of dust, which may also enter the stage equipment and cause damage to the equipment.
Especially in outdoor performances or occasions with a large audience density, the dust problem is more prominent. Therefore, it is necessary to keep the audience area clean and tidy to reduce the generation and raising of dust.
At the same time, dust nets, dust covers, and other protective measures can be set around the stage equipment to further reduce the impact of dust on the equipment.
2. What is the definition and standard of high protection performance of LED display screens?

For LED display screens, obtaining CE certification not only means that its electrical safety performance is fully guaranteed but also indicates that it has met the strict requirements of the European market in terms of electromagnetic compatibility and radiation control.
2.2). RoHS certification:
The RoHS (Restriction of Hazardous Substances) directive is a restrictive requirement formulated by the European Union for the content of specific hazardous substances in electronic and electrical equipment.
The directive clearly stipulates the maximum allowable content of hazardous substances such as lead, mercury, and cadmium in electronic products, aiming to reduce the potential harm of these hazardous substances to human health and the environment.
LED display screens that have obtained RoHS certification have more environmentally friendly material selection, minimizing the impact on human health and the environment.
2.3). Special certification for specific application scenarios:
For specific application scenarios such as outdoor performances, LED display screens must also meet a series of special certification requirements.
For example, considering the impact of stage vibration and impact on the stability of the equipment, the LED display screen must have good anti-seismic performance; at the same time, in order to ensure the stability of the equipment under long-term high-brightness operation, its heat dissipation performance must also meet certain standards.
In addition, for applications in certain special places (such as chemical plants, oil fields, etc.), LED display screens must also have special properties such as explosion-proof and anti-corrosion.
These special certification requirements are based on specific application scenarios and are intended to ensure that the LED display screen can maintain excellent working performance and extend its service life in various harsh environments.
