Description

DESCRIPTION

Luminous wireless seat.

Description

The object of the present invention is a seat made of plastic, wood or any other material, of the type that is placed on cement stands, concrete or similar, and which is characterized by incorporating a decorative light element, but not fed by a electric cable, but powered wirelessly. In this way the seat can be removed and placed by mechanical means, such as fixing screws, but without the need for any electrical connection or intervention. The seat can be intended for venues such as football, tennis or basketball fields, sports centers, bull rings, athletic tracks and a long etcetera.

The wireless power is achieved through the phenomenon of electromagnetic induction, which avoids the use of electrical connection wiring.

Field of application of the invention

The field of application of the present invention is within the technical sector of the seat industry for popular venues, the industry dedicated to the manufacture of decorative elements and in the construction sector.

Previous definitions

We define below, for a better understanding, the relevant terms that will be used frequently in this document:

Inductive current socket: Electrical device through which a variable current flows which in turn generates a variable magnetic field. This variable magnetic field can electrically power another circuit through the phenomenon of electromagnetic induction. A simple electrical cable through which an alternating current circulates can be an inductive current socket.

Receiving or Secondary coil: Magnetic field receiver through which charges will flow due to the effect of electromagnetic induction. Normally this secondary will be a coil of conductive material of circular, rectangular or polygonal shape in general.

A simple electrical cable through which an alternating current circulates can be an inductive current socket.

PCBA: Acronym for "Printed Circuit Board Assembled", which means "card / printed circuit board assembled". It is basically a PCB with assembled or welded electronic components.

LED: Acronym for "LIGHT Emiting Diode." It is an electronic device that emits light, and that is part of most of the bulbs that are manufactured today.

COB LED: Acronym for "LIGHT Emiting Diode", "Chip On Board". It is an electronic device formed by multiple tiny LEDs arranged on a mounting platform, with the appearance of being a larger LED.

LED STRIP: It is a circuit of illumination formed by multiple LEDs, with the form of a rigid strip or flexible tape, which when turned on gives the sensation of forming a strip or luminous strip.

State of the art

Within the uses of a seat is the seat intended for entertainment venues. This type of seats is usually mounted on a concrete step. Since vandalism is frequent in certain sporting or musical events, these seats do not incorporate lighting, since the necessary wiring to illuminate them will be a problem of electrical safety, if they are torn from their position.

That is why no luminous seat has been found after a meticulous search in the market. And of course, note that in the multiple databases consulted when writing this document, there is no type of light seat fed directly by the phenomenon of electromagnetic induction.

It is a fact that in the current market there are few devices powered inductively, and those that are marketed, such as electric toothbrushes or smartphones, work with batteries that have been previously charged wirelessly.

The light seat of the present invention, as an additional novelty, is fed directly from an inductive power outlet, without the need of having a battery as an electrical energy storage element.

It should be mentioned that the author of the present invention has registered the utility model ES1123205, referring to a "Wireless Bulb for inductive power socket", also characterized by not requiring batteries and feeding directly from the inductive power socket.

Description of the invention

The object of the present invention is a seat in which one or several lighting circuits have been incorporated, all of them powered wirelessly and at the same time embedded in the plastic mold itself, which will provide electrical isolation and even sealing to such circuits of lighting.

Basically, the light seat will be made up of the following elements:

1. Solid material presenting on its surface at least one non-opaque area through which the light comes out

2. Receiving or secondary coil

3. Resonance condenser

4. Control circuit

5. Luminous elements

The receiver coil, the resonance capacitor, the control circuit and the light elements will be embedded in the material that makes up the seat.

The control circuit can be an electronic device that modifies the color or the intensity of the luminous elements, from signals received by radiofrequency, or from electrical signals incorporated in the wireless power supply itself.

The luminous elements can be "LED strips", or "LED COBs" arranged in series or parallel, and placed in the place that is of most interest so that their light comes out through the diffusers prepared in the plastic housing of the seat.

The receiver coil, the resonance capacitor, the control circuit and the light elements could be integrated into a printed circuit board, which is known as PCBA. However, in most cases, the receiving or secondary coil will be separated from the PCBA, although it is important to insist that such a receiver coil can also be assembled or integrated into the PCBA's own design.

Sometimes the presence of a PCB printed circuit board is not necessary, as for example, when only a secondary coil, a capacitor, and an LED strip are used as a light element.

The set of the receiver coil and the resonance capacitor will normally be calculated so that their capacitance and inductance values form a resonant circuit. In this way the transfer of wireless power will be produced optimally.

The most important characteristics of the invention are:

The luminous seat is not connected to the electrical network by means of cables or contacts, but it can be installed directly on the surface on which it is going to be placed and it will shine if in its surroundings there is an inductive power socket.

Since an inductive power outlet can be a simple power cable, for the light seat of the invention to shine, it would suffice to be placed "close to" or "over" the power cable, without any connection. In this way and by way of example, a whole row of luminous seats could be fed by simply placing an underground cable in the support floor, prior to the colocation of the row of seats.

The receiver coil embedded in the seat of the invention can be formed by a standard multi-cable hose of the market, which is also known as multipolar cable. This considerably lowers manufacturing costs, since it is not necessary to expressly manufacture the receiver coil. Take into account, as a differentiating element of this invention, since as can be seen in one of the figures that accompany this description, with a single turn of a four-wire hose can be made a mono cable coil with four turns.

The receiver coil can be installed near the outer perimeter edge of the seat base, so that the magnetic flux reception area is maximum, which facilitates the wireless transfer of current.

The luminous seat does not present "living poles", it is dedr, there are not two terminals in which there is a difference of potential, and therefore, there are no risks of accident or electrical incident.

The light seat can be changed very easily by not being electrically connected by means of contacts or connection cables, and also the change or replacement can be done without the danger of electric shock and even with the installation running.

The installation of the light seat is as simple as that of a conventional seat, since it does not have external contacts and can be placed in the desired place as if it were a normal seat, and therefore it can be installed by unqualified personnel. electricity.

The light seat incorporates basic electrical components, in the simplest case it will only house a receiver coil, a resonance capacitor and a light element, so the substitution or manufacture of said devices will be of low production and / or repair cost.

The shape or materials with which the seat is constructed, the shape of the receiving coil and the arrangement of the luminous elements therein, are limiting of the present invention.
