Installation of LED screens demands of the environment

With the development of science and technology, LED screen with particular size, wide Angle, high brightness and color gorgeous and other characteristics, application to play the more extensive, its outstanding advantage as a flat led panel display of the mainstream of the product, in finance, transportation, sports, advertising, and brought Shi widely used. With the quickening of the process of social informatization, the LED display in the information display field of applied will increasingly wide. But, LED screen to the environment? What are the specific requirements, the following points a few respects analysis:

All equipment are able to in this design all weather provisions of the 24 hours of continuous operation, it shall meet the following conditions:

Power supply condition: AC380V plus or minus 10% 50 ± 2 Hz power line three-phase five line system, points in AC220 V plus or minus 10%

Environmental temperature: ℃ ─ 40 ℃

Humidity: 10% ℃ ─ 95% RH

LED screen screen body installation conditions: screen body must be equipped with lightning protection electric device, each a hair into line all needs to take corresponding measures to protect the lightning protection electricity. Equipment must be good anti-disturbance and lightning surge protection characteristics, electrical impulses interference protection and electrostatic interference protection to IEC801 level 3 or more. Equipment case shall have anticorrosive, antirust, waterproof, dustproof function, protection grade GB4208-93 with the IP65.

Metal components should be grounding is good, the work is grounding and lightningproof grounding share, grounding resistance Ω than 4.

Pillar, framework, supporting frame, display enclosure, controller case etc products components should be installed by firm, the structure stability, edge horn transition smoothly, without flash, no burr. All kinds of retaining bolt strong, meet the road shocks and outdoor environment requirements.

Each pixel display light shine even, no Mosaic phenomenon.

To ensure that can display in outdoor all-weather conditions 24 hours of continuous work, circuit boards, etc must be waterproof, moistureproof and anticorrosive processing.

The LED display brightness according to environment to automatically adjust the brightness, can also be remote manual adjustment, adjusting range is not less than 32 level. The light can be in direct sun screen surface conditions during the day, in the provision of range clearly identify display content; Dim, should be in night no glare phenomena.

Module shell material: module shell using modified high strength engineering plastic, join special fight ultraviolet agent, ensure that materials long-term chemical stability, regardless of high temperature or strong ultraviolet ray degradation will not be phenomenon, good deformation parameters of the pixels that distance does not happen in change.
