Other features and advantages of the bow for a bowed string musical instrument will be evident in light of the description of a preferred, but not exclusive, embodiment, which is illustrated by way of a non-limiting example in the drawings which are attached, in which:



BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS
FIG. 1 is a schematic view of a preferred embodiment of the bow for a bowed string musical instrument of the present invention.



DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION
As shown schematically in FIG. 1, the bow for a bowed string musical instrument of the proposed invention comprises a narrow rod 1 and one or several strips 2 or hairs for rubbing on the strings 31 of the same musical instrument 3, in the manner already known in the state of the art.
In this preferred embodiment represented in FIG. 1, the bowed string musical instrument 3 is a violin. In other preferred embodiments not represented in FIG. 1, the bowed string musical instrument 3 can be a cello, a viola, or a double bass, for example, or any other known in the state of the art.
Already according to the invention itself, the bow for a bowed string musical instrument of the present invention incorporates at least one illuminating means disposed on the narrow rod 1, a processing means able to activate and control said illuminating means, and a power supply battery 6 enabled to power the illuminating means.
In this preferred embodiment, it involves a plurality of illuminating means, each illuminating means being an LED 4, and the processing means comprises a microprocessor 5.
Both the LEDs 4 and the microprocessor 5, as well as the power supply battery 6, are disposed on the narrow rod 1, and such that they do not alter the dynamic equilibrium of the bow for a bowed string musical instrument of the invention during use when rubbing the strings 31 of the musical instrument 3.
The power supply battery 6 is rechargeable, for example by means of a USB connector.
The bow for a bowed string musical instrument of the invention can also incorporate a switch 7 with manual actuation disposed on the narrow rod 1 and interposed between the LEDs 4 and the power supply battery 6, and therefore able to turn the LEDs 4 on or off.
Said switch 7 with manual actuation is interleaved between the LEDs 4 and the power supply battery 6, such that the LEDs 4 can stay invariably on or off as desired by the user, and are able to inhibit the actuation of the microprocessor 5 on the LEDs 4.
The microprocessor 5 is able to activate and control the LEDs 4. This activation and control of turning the LEDs 4 on and off is carried out according to a programming incorporated in the microprocessor 5 itself.
The LEDs 4 used also have the possibility of changing the colour of the emitted light, according to the control thereof from the microprocessor 5 programmed to this end.
The microprocessor 5 is programmable, and it can also have Wi-Fi or Bluetooth communication capacity or similar, enabling them to be programmed and controlled remotely and simultaneously to the use of the bow for a bowed string musical instrument of the proposed invention. Therefore, the programming used by the microprocessor 5 and the consequent result obtained in turning the LEDs 4 on and off can be altered remotely, even during the very use of the bow for a bowed string musical instrument of the invention.
In this sense, turning the LEDs 4 on and off can follow a certain rhythmic and repetitive sequence previously programmed in the microprocessor 5 itself.
In another preferred embodiment, according to another programming, the microprocessor 5 is able to activate and control the LEDs 4 following the sound rhythm of the surrounding musical melody, generated by the bowed string musical instrument 3 itself or by the entire orchestra wherein it is integrated, for example. To do so, the bow for a bowed string musical instrument of the proposed invention incorporates a sound recording means 8 and at the same time linked in data communication with the microprocessor 5. According to the surrounding musical melody recorded by the sound recording means 8 and the representative data communicated by the same to the microprocessor 5, the same microprocessor 5 activates and controls turning the LEDs 4 on and off, with an on and off sequence in accordance with the sound rhythm of the surrounding musical melody.
In another preferred embodiment, the microprocessor 5 is able to activate and control the LEDs 4 according to the intensity of pressure exerted by the strips 2 or hairs on the bowed strings 31 of the musical instrument 3. To do so, the bow for a bowed string musical instrument of the proposed invention incorporates a tension recording means 9 physically linked to the strips 2 or hairs, and at the same time linked in data communication with the microprocessor 5. According to the tension recorded by the tension recording means 9 in the strips 2 or hairs and the representative data communicated by the same to the microprocessor 5, the same microprocessor 5 activates and controls turning the LEDs 4 on and off, with an on and off sequence according to the pressure exerted by the strips 2 or hairs on the bowed strings 31 of the musical instrument 3.
The bow for a bowed string musical instrument of the proposed invention, in the different preferred embodiments thereof, maintains a dynamic equilibrium during use when rubbing the strings 31 of the musical instrument 3.
The connection cables between the different elements described stay hidden from view, in order to thus maintain the aesthetics of the bow for a bowed string musical instrument of the invention.
The details, shapes, dimensions and other secondary elements, as well as the materials used in manufacturing the bow for a bowed string musical instrument of the invention, may be suitably replaced with others that are technically equivalent and do not depart from the essential nature of the invention or from the scope defined by the claims included below.
