In related news
analysis, LED display has been occupy the dominant in the field of outdoor
advertising , while at the same time LED display leakage, fire emerging,
brought a great threat to our lives and property. Let us look at the LED
display frequent fire accidents which reasons.
First,
the wire. In most display applications, the unit area of the display shows more
large,the consumption is more big,the greater stability of the wire is
energized with a higher demand. Numerous wire products, used accordance with
the national standard wire can be able to guarantee its safety and stability.
Low quality wire, hidden fire hazards.
Second,
the power supply. The best choice is selection of similar product by UL
certified, the effective conversion rate ensure power load security and stability
in the external environment temperature hot conditions, it can also work.
Third,
the protective material. General outdoor display products of aluminum composite
panel with high temperatures, rain and cold impact of aging faster, make it
more humid climate season segment, rain is easy to penetrate the interior of
the screen resulting in a fire caused by a short circuit electronic components.
In materials display external protective structure, the market higher fire
rating of display products are mostly fire-resistant aluminum panels, excellent
fire resistance, fire retardant is also very strong.
Fourth,
the plastic packages. Plastic packages mainly to mask the bottom case of the
use of modular units materials, mainly used material is fiberglass materials
with flame retardant PC functions, not only fire-retardant features, more at
high and low temperature and long-term use, no distortion, no become brittle
cracking, combined with better sealing glue, can effectively blocking rainwater
penetration into the interior of the external environment in order to cause a
short circuit fire.
In
addition to raw materials will affect the internal fire protection, thermal and
other external design is also very important. LED outdoor display at high temperatures,
heat dissipation is a major challenge, if it is a large area of the display,
but also increased the difficulty of cooling. Previous large outdoor screens
are made fans and other auxiliary heat, was developed to internal
self-installed air conditioning. Good heat dissipation performance, one can
prevent fire, on the other hand, you can also extend the life of the display.
Of
course, the fire also with local environmental factors such as temperature,
humidity, and human error related to temperature, humidity, rain, lightning,
and other weather factors, and improper operation of construction and technical
personnel are likely to cause accidents.
After
understand the causes of fire accidents, targeted preventive measures will help
to build a secure and harmonious social environment.
