    BACKGROUND OF THE INVENTION
    The existence of electroluminescent lamps is known which, consisting of sheets formed by several layers, emit their own light when connected to a power supply 5, being normally intended to be incorporated into
    clothing for protection and safety in situations of poor visibility.
    Specifically, applications of this type of lamps are known in safety helmets, for example, for cyclists or motorcyclists. 10
    For example, documents US5327587, US5426792, US2015195890, KR101412341, US2006133068, JPH10226916 and JPH08202282 describe safety helmets with electroluminescent elements. For its part, patent application ES201430685 describes an electroluminescent element according to the preamble of the
    Claim 1.
    The systems of these prior art documents comprise:
    to. lamps formed in electroluminescent bands that must be superimposed on the surface of a helmet, and
    b. Power batteries for electroluminescent lamps that must be replaced or charged periodically.
    This implies two drawbacks that, in practice, have limited the application and commercialization of these types of safety helmets.
    The present invention aims to provide a safety helmet with electroluminescent elements that simultaneously solve both problems.
    30 EXPLANATION OF THE INVENTION
    For this purpose, the object of the present invention is a safety helmet, of novel concept and functionality, which, according to the preamble of claim 1, is of the type of those comprising light elements
    electroluminescent (EL), on a band or plate provided with at least one electroluminescent flexible lamp; an electronic control circuit; a battery for electric charging of electroluminescent lamps; being electrically connected by electrodes with the lamps; and a battery charging means, all of it
    5 on a substrate or flexible sheet.
    In essence, the helmet of the invention, according to the characterizing part of claim 1, is characterized in that said battery charging means includes a wireless charging device.
    In accordance with another feature of the present invention, electroluminescent lamps; the electronic control circuit; the electrodes; and the battery charging means, are printed on said sheet substrate.
    In another complementary embodiment of the invention, the wireless charging device is a magnetic induction charging device.
    In this case, the wireless magnetic induction charging device may comprise receiving coils in the electronic control circuit of the board, 20 connected to the battery, and emitting coils in an external charging device, which is magnetically coupled to the coil of the electroluminescent plate, at a
    default concrete frequency.
    This predetermined specific frequency may preferably be 136 25 kHz or 13.56 MHz.
    The sheet substrate on which the different electronics element and the EL lamps are is preferably a sheet embedded in the hull, the preferred material being a polyimide. However the sheet substrate material
    30 can be virtually any, even textile, but the main advantage of polyimide is that it allows conventional welding on it. Other materials with this property are also possible, such as for example Nomex®, Kevlar®, Technora® or other aramids, polyethylene naphthalate (PEN) or other polyesters,
    fiberglass or even flexible glass film.
    According to another characteristic of the helmet of the invention, the different elements mounted on the substrate are encapsulated in a plastic wrap, plastic that allows the joint injection in the manufacturing process of the helmet, being the
    5 preferred plastic materials polycarbonate and polyester, not excluding otherpossibilities.

    15 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION
    In view of the aforementioned figures, and according to the numbering adopted, a non-limiting embodiment of the hull of
    20 security 1 with electroluminescent light elements (EL) 10 recommended, which comprises the parts and elements indicated and described in detail below. The safety helmet incorporates electroluminescent (EL) light elements in order to increase user visibility in low light conditions.
    The safety helmet 1 with electroluminescent light elements of the invention comprises, arranged on a sheet substrate 2:
    30 an electroluminescent band 10 provided with two electroluminescent lamps 14 and 6 (or EL lamps), of known type, which make up the electroluminescent element in question, and of direct current (DC) power supply; an electronic control circuit 13, with a microprocessor 31;
    35 a battery 5 for the operation of the electronic control circuit 31 and
    the inverter 15;two electrodes 7, 8 which are electrically connected with the EL 14 and 6 lamps;an induction charging device 4 of the battery 5; Yan inverter 15 to convert the direct current (DC) of the battery into the
    5 AC power required for EL 14 and 6 lamps.
    All of the above elements are interconnected with copper printed on said sheet substrate 2. This sheet substrate 2 is, in the embodiment illustrated, a flexible sheet of polyimide embedded in the hull 1, as may be
    10 see in Figs. 3, 5 AND 6. The sheet substrate 2 can be flexible or rigid. The preferred material is polyimide, since it allows conventional welding on it. Other materials with this property are also possible, such as for example Nomex®, Kevlar «, Technora® or other aramids, polyethylene naphthalate (PEN) or other polyesters, fiberglass or even flexible glass film.
    The different elements mounted on the substrate 2, including the latter, are encapsulated in a plastic wrap 11, preferably polyester or polycarbonate. The band EL 10 with all its elements, as well as the wrapping plastic 11 of the package, are embedded in the outer shell 200,
    20 normally made of polycarbonate or PE, of the hull 1, leaving the inner layer 100, usually of PE or PVC, free and intact thereof.
    Said light elements 1, 5 and the encapsulated electronics are extremely thin (less than 0.5 mm), which allows them to be grafted into the helmet itself 1 by uln-Mold 'techniques, resulting in an excellent finish, in which The EL 10 band itself forms part of the outer shell 200 of the helmet 1 without it being removable. The material of the substrate 2 is polyimide (for example Kapton® from Dupont®). Polyimide is the preferred material because it holds a lot of temperature, more than 4500 without deformation and in the injection of the helmet it is important
    30 this feature. Polyimide also allows conventional welding on it. Other materials with this property are also possible, such as, for example, Nomex®, Kevlar®, Technora® or other aramids, polyethylene naphthalate (PEN) or other polyesters, fiberglass or even flexible glass film.
    In Figs. 5 and 6 it can be seen that on one side of the polyimide substrate 2
    EL 14 and 6 lamps are printed and the electrical circuit itself for the electronic components, and on the other side the antenna / coil of the wireless induction charger and the electrodes of the capacitive / inductive sensor are printed, in addition to circuit 39 of the optical sensor 38. These encapsulated or assembled elements are shown in Fig. 4
    5 in a set 13, of electronics, charging and control, which may include printed circuits13 on the substrate 2 of polyimide itself.
    Next, the operation of the different EL and electronic light elements of the present invention is defined and explained, especially in relation to Fig. 7. Note that in Fig. 7 the elements and components of the electroluminescent band 10 are represented. with a darker stroke and enclosed in a block 10. In this figure, some elements have been indicated with the terms with which they are commonly known in the electronics and communications sector (usually with abbreviations or denominations in English) .
    The operation of the EL 14 and 6 lamps is based on a DC / AC 15 inverter (Figs. 6 and 7). Said inverter 15 converts the direct current of the battery 5 to alternating current with voltage and frequency values optimized for the operation of the lamps EL 14 and 6. The inverter 15 can also be
    20 embedded in an electronic control circuit 3, together with the sensor, communication elements and a microprocessor 31 (Fig. 7).
    The control of the inverter 15 is carried out by means of a small microprocessor 31, embedded in the electronic control circuit 3, in order to be able to control the ignition time 25, the frequency of "flashing" or flashing, the light intensity or
    Any other mode of operation. This control can be activated manually, automatically or remotely.
    When activated manually, the user presses a button 27 (Fig. 7) of the
    30 safety helmet 1 to enable it to be activated via manual "ON / OFF" control 28. Each time button 27 is pressed, you can change the operating mode, such as continuous, intermittent and off. These functions depend on the microprocessor program 31.
    35 When the control is activated automatically, the activation can be
    P201 531236
    5 perform when detecting that the helmet 1 has been placed on the user's head and optionally, there is insufficient light to activate the system. It can also be activated when helmet 1 is in motion and optionally there is insufficient light. Among these sensor elements, a light sensor 9 and an optical sensor 38 have been illustrated (Figs. 6 and 7). Also shown in Fig. 7 is the motion sensor 16 and an accelerometer 29 that provide their signals to a control block "ON / OFF ~ 26 of the sensor inputs for the case of" helmet on. "
    1O For the "helmet-put" control, preferably a presence sensor is used which can be magnetic / mechanical, optical 38 or inductive / capacitive 17. For motion activation, the accelerometer sensor 29 already indicated is preferably used, But it can also be vibration, or mechanical, or a gyroscope.
    fifteen In the light sensor 9, the detection of insufficient light can be carried out by means of a light-sensitive resistor type LDR ("Light Depending Resistor") 23, and it can also be carried out by means of a photovoltaic solar cell 24, and that at the same time it can charge the battery 5.
    20 25 When the control is remote, the start-up system and / or operating mode is performed wirelessly through a wireless communications port 25. This wireless connection can be established between a mobile device type Smartphone 21, a remote control 22, which can be installed on the handlebar or the user's wrist. In general, the sensors and detectors can be optical, capacitive, inductive or by mechanical sensor, for example a physical contact for when the head of the user touches the helmet 2.
    30 The wireless connection between the helmet 1 and any of the devices is preferably by means of Bluetooth 18 technology, but it can also be made by an NFC, ANT + 19 input or by any standard or proprietary wireless communications system / technology.
    One of the main novel features of helmet 1 is presented in the
    Battery charging system 5, which is done by magnetic induction. This consists of passing the energy to the battery 5 wirelessly by means of coils 4 (Figs. 4 and 7) magnetically coupled. This does not require any type of cable or electrical connection between the safety helmet 1 and the external charger
    5 30 (Fig. 7).
    The operation of this type of energy transfer system is based on the same as a galvanic transformer, that is, a magnetic coupling of two coils is made at a certain frequency. One of the coils is the
    10 receiving coil located in the charging device 4 of the hull 1. In the present case, the 135 kHz free-use frequency is used, but 13.56 MHz could also be used. Said circuit oscillates a signal at said frequency, the The circuit is adjusted to resonate at the working frequency, obtaining optimum performance, both in the antenna or transmitter coil and in the receiver. The receiver circuit, with coils 4,
    15 is responsible for transforming the received alternating signal into a continuous signal to charge the battery 5.
    It is also provided that the battery 5 of the helmet 1 of the invention can be electrically charged, for example by means of a USB device 12 or similar (see Fig. 20 2).
    The inventors have contemplated the possibility of a variant, not shown in the drawings, in which the band 10 is not built "In-Mole!" or embedded in a helmet 1, but as an accessory and independent band 10, which on one side would have a
    25 adhesive to adhere to the helmet. In this case, the EL 2 band and the helmet could be sold separately.
    Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to make its
    30 explanation so that any expert in the field understands its scope and the advantages that derive from it, stating that, within its essentiality, it can be put into practice in other embodiments that differ in detail from that indicated by title as an example, and to which it will also achieve the protection that is sought as long as it does not alter, change or modify its fundamental principle.
