Alas, are friends who have just entered the industry often confused by this question? Yesterday a customer asked me: "Old Wang, I spent 200,000 yuan to install the LED large screen. Why did the urban management team need to dismantle it when they say it? "Actually, there is a lot of knowledge here. Let’s break it up and talk about the pits that novices are most likely to step on...

​​Let me first talk about why I need to approve it​​
Do you know? Last year, more than 300 outdoor screens in Shenzhen were forced to demolish due to incomplete procedures. Take the most common outdoor advertising screens as an example. You have to pass five or six department levels at the same time. It’s not to scare you. I have seen someone investing in a million screen, but because they didn’t report it next to the green belt, they finally dismantled it.

​​List of core approval departments​​

1. Municipal Appearance Administration (Contacts Advertising Content Compliance)
2. Urban and Rural Planning Bureau (see whether the installation location is in line with the planning)
3. Housing and Construction Department (review of steel structure safety)
4. Environmental Protection Agency (evaluation of light pollution and noise)
5. Electric Power Company (Electric Load Approval)
   Especially for transparent screens with a transmissibility of more than 86%, the environmental protection approval is stricter, and special glare test reports must be made.

​​Prepare three major items of materials​​
Last year, I helped the client with urgent approval, and the list of materials still exists in my mobile phone:

• Certificate of use of the site (original document that the landlord wants to stamp out)
• Structural safety appraisal certificate (you must find a qualified testing agency)
• Brightness adjustment solution (such as the intelligent system that can automatically adjust 4000-7500cd/m² is the most popular)
  Remind you: The fence screen used in sports stadiums also requires additional lightning protection inspection reports, which many people will miss.

​​Pay attention to time cost​​
The normal process takes about 25 working days, but if you catch up with major events - for example, during the Hangzhou Asian Games last year, a customer installed a competition display screen, and the Hierarchical Environmental Protection Evaluation delayed for two months. Now I know why professional engineering screens have to be planned half a year in advance?

​​Self-questioning session​​
Q: Why do others approve the same screen faster than me?
A: The trick is to consider the approval requirements in the design stage of the plan. For example, if you make a window screen, you can write the automatic brightness reduction function at night into the plan in advance, so it will be much better for environmental protection.

Q: What should I do if I am asked to make rectifications?
Once, the customer's screen was too close to the residential building, so we changed the cooling system overnight and installed soundproof cotton before passing the test. Remember: the rectification notice is not a death sentence, and it is still possible to find professionals to adjust the plan in time.

​​Tears of blood and tears three times​​

1. Don't believe the nonsense of "installing first and replenishing later". The LED walls that were forced to be demolished in Shanghai last year were so useless
2. Apply for power capacity expansion as early as possible, and a customer will rust the equipment when the approval is approved.
3. Maintenance plan must also be reported! Many places now require a three-year warranty agreement

Speaking of this, I suddenly remembered something - last month, a customer who made a shopping mall poster screen failed to write down anti-dumping measures in the plan, and the approval was blocked for a full three weeks. So, you can't be careless about every detail.

Editor's opinion: Approval is like an exam, and memorizing the answers in advance will naturally go smoothly. Those who always think "just as long as they are" will have to pay tuition fees sooner or later. Remember, compliance operations are the long-term way for the LED display industry.
