  • the minimum voltage value Umin for the minimum frequency Fmin is expected to be above said threshold voltage Us
  • the regulation device 1000 is arranged so as not to include any means of dissipating kinetic energy from the rotor 10 of the micro-generator 100. It is understood that the invention does not brake the rotor to reduce its frequency, but only to prevent its frequency from increasing.
  • the motor device is equipped with a barrel 200 dimensioned so that the useful range of the torque it delivers, between the minimum motor torque C MotMin and the maximum motor torque C MotMax , is such that the minimum motor torque C MotMin is equal to the sum of a mechanical torque C MecVmin required to drive the mechanism driven by the barrel, excluding the rotor 10 of the micro-generator 100, with the rotating part 1 rotating at the minimum speed V min , on the one hand, and a minimum rotor drive torque C EDmin corresponding to the minimum frequency F min of the rotor 10, on the other hand, and such that the maximum motor torque C MotMax is equal to the sum of a mechanical torque C MecVmax required to drive the mechanism, excluding the rotor 10 of the micro-generator 100, with the rotating part 1 rotating at the maximum speed V max , on the one hand, and a drive torque of the maximum rotor C EDmax corresponding to the maximum frequency F max of the rotor on the other hand.
  • the light-emitting diode or several light-emitting diodes 31, 32 are chosen in such a number that, according to their type and dimensions, the set of light-emitting diodes 31, 32 comprising the regulation device 1000 is arranged to perform electrical dissipation with a rotor drive torque between the rotor drive torque minimum C EDmin , corresponding to the minimum frequency F min , and the maximum rotor drive torque C EDmax, corresponding to the maximum frequency F max , on the other hand, as seen on the figure 7 .
  • an indirect supply of at least one LED 31, 32 is chosen by the micro-generator 100, and at least one LED 31, 32 is connected to the micro-generator 100 through an electrical and/or electronic circuit without a substantial storage component for an electric current induced in the coils 11 during a rotation of the rotor 10 of the micro-generator 100.
  • the invention implements passive regulation, requiring no electronic circuitry for data processing and control of the regulation.
  • Powering LEDs directly or indirectly via an electrical/electronic circuit, without substantial electrical energy storage components, using a micro-generator for a mobile speed control device is a novel concept that combines high efficiency, compactness, a small number of components, and reduced cost. Furthermore, such a device allows for a robust and relatively high-end design, suitable for high-end watchmaking.
  • the invention also eliminates the need for fragile, wear-prone moving mechanical components, such as those used in inertial governors, aerodynamic governors, or eddy current governors. It also eliminates the need for mechanical return mechanisms such as springs.
  • the invention has numerous advantages.
  • Arranging the LEDs directly on the micro-generator eliminates the need for contact connections, conductive wires, or printed circuit board (PCB) traces. This ensures compatibility with high-end watchmaking. Their advantageous arrangement on the rotor prevents the presence of any An electronic component composed of materials incompatible with a high-end mechanical watch.
  • LEDs are the only components that could be considered “electronic,” but their composition is inorganic, and the vast majority of the volume is made of crystal and metal. Therefore, the proposed arrangement is aesthetically discreet and also compatible with a skeleton watch construction with a visible mechanism.
  • LEDs light-emitting diodes
  • a smoothing capacitor on the rotor could be used, this does not appear necessary because the rotor rotates at a relatively high frequency, making the periodic variation in brightness imperceptible to the human eye when the LEDs are used to illuminate a visible part of the timepiece.
  • the preferred embodiment of the invention offers the advantage of a passive circuit without any intermediate energy storage, thanks to the direct powering of each diode by the coils, thus eliminating the need for an induced voltage rectifier or smoothing capacitor.
  • the light-emitting diode does not provide sustained brightness when the current is switched off, but the user's eye perceives a persistent illumination because, with a rotation speed on the order of hundreds of Hertz and, for example, 12 or 14 poles in the micro-generator, there is a flicker on the order of kHz, imperceptible to the naked eye.
  • a rotation speed on the order of hundreds of Hertz and, for example, 12 or 14 poles in the micro-generator
  • small braking torques a thousand times per second will smooth the rotational frequency.
  • An energy storage capacitor is not desirable because its voltage variation would not keep pace with the induced voltage variation sufficiently, and would therefore be inefficient for speed regulation.
  • LEDs rotate at high frequencies, they generate a nearly continuous and uniform ring-shaped light distribution, visible to the human eye, with a surface area much greater than that of a standard LED.
