Description

"LIGHT PANELS ENABLED BY SOLAR AND WIND ENERGY". Fields of this Patent:

• Reduction of electricity costs for indoor or outdoor panel lighting;

• Maintenance of lighting in luminous panels of high social relevance, in case of lack of electricity in the public grid.

• Energy self-sufficiency in light panels as a practical demonstration of commitment to reduce advertisers' carbon footprint.

State of the art.

Ten years ago the issue of global warming was restricted to the experts and the minority heavily involved in environmental issues; after all, if the temperature of the planet's atmospheric layers and surface waters would rise by 0.5 ° C over the next ten years, for ordinary people, this value seemed to be negligible for personal thermal comfort.

Contrary to common sense, temperature increases of this magnitude profoundly affect the biosphere.

Published studies showing the extinctions of various species each time, over the past billion years, landslides in the "Grand Canyon" escarpments disrupted the flow of the Colorado River, forming floods that caused water due to the larger catchment area. if they heat up to around 0.5 ° C are far from ordinary citizens.

However, in recent years the weather has become the main daily tragedy shown by the media; prolonged droughts alternating with floods, blizzards, hurricanes, the big cities helpless in the face of the rage of the elements, the great impacts on humans and animals, all of this made the common man to worry about the multiple phenomena arising from the global warming, becoming aware of the "carbon footprint" of every human activity, even seemingly innocuous ones such as surfing the internet.

Involving mega-companies with powerful opinion-forming powers, such as Google and Microsoft, in brave solutions to diminish their "Carbon footprints" broadened the common man's understanding that the solution is the old ecological "mantra": "Think globally, but act locally."

Environmental responsibility has become extremely important for companies as consumers have clearly manifested themselves as being able to avoid doing business with companies that do not respect their environmental obligations.

The moment when companies are most at risk of getting results contrary to their purposes is when they advertise, because this activity fundamentally draws everyone's attention to the name of the advertiser.

Conversely, activities and promotions by companies aimed at energy self-sufficiency, reducing the environmental impact of their products, the use of recycled or recyclable materials and others are very well received by consumers and raise the prestige of these companies in the impacted communities.

Due to competition, there is no longer a way for high-exposure companies to act without realistically showing their environmental actions. The object of this Patent - "Solar and Wind Power Activated Light Panels" - refers to a communication resource that brings to the communities the names of the advertisers committed, of course, by decreasing their "carbon footprints" by advertise via energy-efficient light panels.

Due to the current state of the art, large light panels may have only one illuminated face - such as those affixed to building faces or directed only to one way traffic - or two or more faces. and consist of equipment that consumes large amounts of electricity.

The faces carrying the advertising messages can be front-lit - front light panels - or backlit - back-light panels. Panels of the first type currently avoid incandescent lamps and use electric discharge lamps such as mercury vapor or sodium, for energy saving and maintenance costs for lamp replacement.

Back light panels are replacing their tubular fluorescent lamps with LEDs, as these devices turn 70% of the electrical energy they consume into light energy, compared to just 15% of fluorescent lamps and 10% of incandescent lamps, and have much longer useful lives.

A third type of light panel is the high power "RGB - Red, Green, Blue" LED panel, which acts as a large video terminal, achieving good resolution and color fidelity effects, placed indoors or outdoors. and that displays moving images.

A fourth type of panel is the monochromatic or polychromatic LED panel, intended primarily to pass information in the form of texts, indoors or outdoors, being a type of panel of high social relevance, being widely used to guide traffic vehicles on major urban roads, informing drivers to avoid or prefer certain roads.

All four types of light panels mentioned above, which make up the state of the art, are powered by the public electricity grid; However, in the absence of this, while the first three types only deprive advertisers of the delivery of their messages, the LED panel for the dissemination of text messages, being deactivated, usually in times of their greatest need, leads to great losses. social,

Advances to the State of the Art brought by the "Luminous Panels"

ACTIVATED BY SOLAR AND WIND ENERGY ", object of this Patent.

The "LIGHT PANELS ENABLED BY SOLAR AND WIND ENERGY", object of this Patent advance the State of the Art by the following innovations:

1st - solar energy capture and wind power, by transforming them into electricity, storage and supply of the electricity generated to the times when sunlight or winds are not so that the panels can be operated for long periods, even in the absence of sunlight and or winds.

2 ^o - The capture of solar and wind energy can be done by devices juxtaposed to the panels, or remotely.

3 ^o - Solar and / or wind energy capture devices, as well as electric energy management devices generated by both processes, can be used in light panels of any type of illumination - frontal or internal - including those whose messages be made by leds.

4 - Preferably, the innovations of the object of this patent refer to capture and storage of solar energy and or wind for pickups and hosts devices smaller and costs and the use of these energies in type lighting "front light" with modern LEDs High brightness and energy performance replacing gas discharge lamps. 4 - In the case of high social relevance panels, which need to be operating is even greater in times of acute weather events such as storms, blizzards, typhoons and other, which often cause interruptions of supply of electricity, the devices solar and / or wind energy capture systems, as well as the storage and management devices for the electrical energy generated by both processes are a reliable power supply for critical moments.

5th - The panels, object of this patent were developed by an expert in communication and consist of the embodiment of the proposition made in the seventies of the last century, by one of the greatest theoreticians of Communication Science - Marshal Mac Luhan - "The medium is the message". In fact, a panel endowed with seductive light features employing modern digital language placed in an urban reference point working with its own resources embodies the advertiser's commitment to the environment.
