The requirements for the anti-interference ability of stage lights when purchasing them

When choosing stage lights, there are strict requirements for the anti-interference ability of the lamps. The anti-interference ability is directly related to the stable operation of stage lights in complex electromagnetic environments and the smooth progress of performances. The following is a detailed analysis of the anti-interference capability requirements for stage lights:

First, the importance of anti-interference ability

Ensure the quality of the performance

Stage lighting, as an important component of a performance, its stable operation is the key to ensuring the quality of the performance. Stage lights with strong anti-interference ability can resist external electromagnetic interference, avoiding problems such as light flickering and loss of control caused by interference, thus ensuring the smooth progress of the performance.

Improve equipment reliability:

Stage lighting fixtures with strong anti-interference ability have higher equipment reliability. In the complex and ever-changing performance environment, it can work stably, reduce the probability of faults, and lower maintenance costs.

Second, the requirement for anti-interference capability

Electromagnetic compatibility (EMC) performance

Stage lights should have good electromagnetic compatibility performance, including two aspects: electromagnetic interference (EMI) and electromagnetic immunity (EMS).

EMI requirements: The electromagnetic interference generated by stage lights during normal operation must not exceed certain limits to prevent interference with surrounding equipment such as audio and video devices. This usually requires that stage lights comply with relevant national standards, such as GB 17743-2007 "Limits and Methods of Measurement for Radio Disturbance Characteristics of Electrical Lighting and Similar Equipment", etc.

EMS requirements: Stage lights should have a certain degree of electromagnetic immunity, that is, they should be able to resist external electromagnetic interference and maintain a normal working state. This usually requires that stage lights take necessary anti-interference measures during the design and manufacturing process, such as using shielded cables and installing filters, etc.

Anti-interference index of dimming cabinet:

As an important component of the stage lighting control system, the dimming cabinet's anti-interference ability is equally crucial. The dimming cabinet should have good anti-interference ability to ensure stable operation in a complex electromagnetic environment and avoid problems such as dimming loss of control and signal loss caused by interference.

Signal transmission stability

The signal transmission between the stage lights and the control system should remain stable. Stage lights with strong anti-interference ability can resist external electromagnetic interference, ensuring the accuracy and reliability of signal transmission and avoiding problems such as light loss of control and flickering caused by interference.

Third, how to evaluate the anti-interference ability of stage lights

View product certification and test reports:

When choosing stage lights, it is necessary to check whether the product has passed the relevant EMC certification and test report. These certifications and reports usually objectively reflect the anti-interference ability of stage lights.

Understand product design and manufacturing processes:

The anti-interference ability of stage lights is closely related to their design and manufacturing process. When making a purchase, you can learn about the design and manufacturing process of the product, such as whether shielded cables, filters and other anti-interference measures are used, and whether high-quality electronic components are adopted, etc.

Actual test

When conditions permit, actual tests can be conducted on stage lights to evaluate their stable operation capabilities in complex electromagnetic environments.

Fourth, Summary

When choosing stage lights, there are strict requirements for the anti-interference ability of the lamps. Stage lights with strong anti-interference ability can ensure the smooth progress of performances, enhance the reliability of equipment, and reduce maintenance costs. When making a purchase, attention should be paid to the electromagnetic compatibility performance of the stage lights, the anti-interference index of the dimming cabinet, and the stability of signal transmission, etc. The anti-interference ability of the stage lights can be evaluated by checking the product certification and test reports, understanding the product design and manufacturing process, and conducting actual tests.
