More and more led screen is installed all over the world, but not so many people take care the installation issue, here in this email, some people will install the led screen neglecting government standard or lower the standard of steel structure, cable quality etc, i will introduce some points about the installation work of led screen:
The working environment of led screen is not that bad, sun, rain, there will have shortage happen once the electronic product is damaged even fire.
Led screen is easily to be attacked by the thunder, lighting.
Usually the outdoor led screen is a few square meter even hundred square meter, it request wider view angle, but some installation site will face to sun directly which will affect the view effect
Big temperature change during night and daytime, there will have heat produced when the led screen is working, if the environment is too high, then heat dissipation will be a serious problem, it could have the led screen burned without good solution; if the temperature is too low, the led screen can not work under extreme low temperature.
Here it will be the solution to above mentioned questions:
The steel structure needs to be strong enough considering the base, wind load, waterproof, dust-proof, moistureproof, temperature, lightning-protection etc; and power distribution box, air condition, lighting etc needs to be considered. The steel structure needs to get a permit from government.
Scaffold is an important step also, the solution needs to be qualified.
The power supply system needs to be conformed to local power use standard, led screen is industrial power use standard, three-phase power supply, grounding protection, leakage protection
The led screen and installation site needs to be combined well, design good drainage protection; waterproof level should be at least IP65/IP54
Led screen inside temperature needs to be -10 – +40 degree, could install axail flow fan behind the led screen; choose -40 – +80 industrial drive ic’choose lower power supply if the temperate is too low
Install lightning protection in case big current from lightning could release; thunder could attack led screen, so need to set ground protection, put metal shell, cable metal shell, metal frame of led screen inside on ground
Prepare 1 unit power distribution box once the power consumption is bigger than 10KW, add leakage protection, leakage switch; you could also add the LCD controller in the power distribution box to display the real time temperature, once the led screen inside is over 65 degree, it will remind it and send warming sound, then cut off power automatically to prevent fire.
