If they are known as "the light of tomorrow" there must be a reason, and it only partly has to do with efficiency. In fact, the LEDs that illuminate many of today's illuminated signs are not only highly efficient and durable, but also environmentally friendly.
The reason, indeed the reasons, are simple: they have a longer life cycle, do not pollute and guarantee high energy savings. Let's start from the first point: LEDs have an average life of 50-100 thousand more hours than traditional lighting. For this reason, they require less maintenance.
Once exhausted, LED illuminated signs do not pollute the environment because they contain neither the 49 phosphors contained in fluorescent tubes, nor the dangerous, highly toxic gases such as mercury vapour, which can cause serious forms of soil and water pollution.
The high energy savings that can be achieved with these light-emitting diodes, quantifiable around 50-70% compared to traditional lamps, guarantees a strong reduction of carbon dioxide.
Finally, the LEDs of the illuminated signs generate heat, but retain it inside, so that the casing controls the heat produce, gradually releasing it with less impact on the environment.
There are few Italian companies that can boast such experience and expertise in design and manufacture energy-efficient LED signs. Among these there is Eliosneon, to whom we owe the realization in the 1930s of the first neon luminous sign in the history of our country.
