At this time I have been requested twice concerning the IP ranking in relation to LED big screens. This can be a very good query that anyone approaching the business ought to ask himself and (most of all) ask the LED show producer.

So let’s begin from the fundamentals: IP is the acronym of ingress safety and it identifies the “safety” in opposition to humidity and suspended particles. The IP degree is described by two figures: the primary one is referred to the safety degree in opposition to mud (together with air pollution), the second in opposition to water.

The ingress safety degree is a global normal and it’s utilized to measure the waterproofness of any digital system. Merchandise with a better IP degree maintain the interior parts safer and cleaner, whereas decrease IPs implies that the system could be water and dirt delicate.

This ingress safety degree is especially vital when the enormous display is supposed for out of doors use – whereas it turned virtually insignificant for indoor purposes, the place there is no such thing as a threat of rain and air pollution.

So you’re in all probability questioning what’s the precise definition of IP65? Right here we go:

*6 (Mud) Mud-tight. No ingress of mud.

* 5 (Water) Protected in opposition to water jets. Water projected from a nozzle in opposition to the enclosure from any route shall haven’t any dangerous impact.

Now, if you’re curious concerning the IP fee, you can additionally ask: how can the display be dust-tight if in case you have a pressured air flow system? Would not the mud enter along with the air?

Within the LED big screens business, the IP fee is often referred to the entrance facet (not the rear facet) of the display, which is most uncovered to the atmospheric brokers, and is subsequently extra prone to be careworn.

Please be aware that this info isn’t clearly acknowledged by all LED big screens producers: a few of them don’t specify it on their brochures or web sites that the IP65 is referred solely to the entrance, to not the rear.

Certainly the safety degree on the rear facet is often decrease, at IP64. LED screens lightall with IP63 or decrease shouldn’t be utilized in out of doors setting, so when evaluating totally different producers, please be sure you double-check with them what’s the rear facet IP fee.

Keep in mind, you can check their honesty and professionalism by asking: “How can the module be dust-tight if in case you have a pressured air flow system? Would not the mud enter along with the air?” – after which see how they reply you.
