- this end comprises at least one bevel 44 for receiving light according to FIG. a direction D substantially perpendicular to a plane parallel to two parallel planes P1, P2, defined by the upper 41 and lower 42 faces of the watch component 1.
- the direction D is advantageously parallel to the axis A of pivoting of the shaft 2.
- the invention makes it possible to produce the watch component 1 as a light guide with controlled losses throughout the watch component.
- the illumination of the watch component 1 is not necessarily in a preferred direction, in fact, it can be done by an upper face 41 (plane P1 of the figures), and / or by the transverse faces 46 and 47 of the watch component 1 .
- variable illumination according to the movement of the watch component, for example to simulate the beat of a human heart: in particular, the watch component can be illuminated over its entire length when the turns are close to each other, and reduce this illumination to minimum (extinguishing effect) when the turns are distant from each other; or the opposite. Loss control is then done according to the position of the turns;
- the coupling between the light source 5, or the relay 50, and the watch component 1, may result from their proximity: the source 5 or the relay 50 emits light with a sufficient energy level so that the watch component 1 can capture this light, before re-broadcasting it.
- the coupling may also be advantageously and preferably carried out by direct contact, surface-to-surface contact, or by plug-in, or by any known technology in the light guides and in the optical fibers.
- the light is concentrated upstream of its sending to the watch component, or when entering the watch component 1, at a concentrator.
- the concentrator is integrated with the watch component 1 during its manufacture.
- the distribution of the stresses in the watch component 1 varies during the contraction or elongation of this watch component for a given adjustment. It also varies during a change in characteristics of the mobile watch component: In the case of a spiral spring of a regulator, in particular, as a function of the amplitude of oscillation of the shaft 2; a variation of the illumination of the watch component 1 can thus make it possible to highlight a modification of the amplitude.
- the watch component 1 according to the invention may not be homogeneous, which then makes it possible to create special technical features, and differentiated light scattering zones.
- Amorphize is used here to mean changing the structure so as to modify the refractive index.
- a coil can be locally amorphized, in particular by laser treatment.
- the watch component 1 may be, at least locally, polished.
- a particular mechanical structuring makes it possible to create chosen light leakage surfaces with particular orientations on certain faces and in particular locations.
- the problem of guiding and diffusing light over the entire length of a watch component 1 which may have a large developed length may cause some turns to be neutralized, or certain portions of turns, by preventing the light from escaping from them. for example by reflective layer deposits or savings of similar functionality. This then allows a saving of light, and the light guide to the ends 6 and 7 of the watch component 1.
- the mobile watch component 1 comprises at least one elastic and deformable part, and the light diffusion through this mobile watch component 1 is variable according to the constraints in this elastic and deformable part.
- the watchmaking mobile component 1 is an energy storage spring or a mainspring or a striking spring, and its illumination mode displays its remaining power reserve.
- the mobile watch component 1 is a game recovery spring. More particularly, it constitutes a game recovery spring for an altimeter watch.
- the clockwise mobile component 1 is a split-spring.
- the clockwise mobile component 1 is a jumper or a jumper spring
- the component 1 may, again, be a spiral spring of the same material that would have other functions than that in a regulating member.
- the component 1 may, again, be a quartz spiral spring intended to be used as a return spring to eliminate the play of a needle, or the like.
- the light source 5 can take various forms. Preferably, this source 5 is an electroluminescent diode or a phosphorescent or fluorescent component.
- the source 5 is phosphorescent and / or fluorescent, preferably phosphorescent due to the longer duration of remanence, which can reach several hours, and is compatible with a possibility of illumination of the watch component at any time during the period of time. a night.
- the source of light will be "phosphorescent" in the rest of the presentation.
- a phosphorescent source advantageously comprises rare earth aluminates, well known to physicists, for example strontium aluminate SrAI204 doped with europium, a variety of which is known under the name “Super-LumiNova”, or rare earth silicates, or a mixture of aluminates and rare earth silicates.
- Other trading materials such as “Lumibrite” are also suitable.
- Materials such as tritium 3H, promethium 147, or radium 226 have excellent phosphorescent properties, but their high beta and / or gamma radioactivity severely limit their use, and they can only be used in large quantities.
- the excitation light comes from the user's environment, solar light, ambient light.
- the light source is housed in the interior volume of the timepiece box or the watch.
- the ambient energy can be collected at a partially or completely transparent, or translucent middle and / or at a partially or totally transparent, or translucent dial, or / and still at a display window , especially for a calendar or the like.
- the ambient energy may, again, be collected by an adjoining accessory to the timepiece, such as a watchband, and be transmitted by a waveguide or an optical fiber, or the like. In the same way, the capture of ambient energy can be performed at the level of other elements of dressing such as the bottom, the telescope, the flange, or others.
- the light source 5 can emit monochromatic pulsed light.
- One of the preferred applications of the invention is the visualization of the internal stresses within the watch component, revealed by the light coming from the light source 5, transmitted and diffused by the component 1.
- the invention also relates to a watchmaking mechanical movement comprising at least one such timepiece display 4.
- the light source 5 is either located at this timepiece display 4 or is deported out of this timepiece display 4 and at the same time. inside the movement 10 in which case it is connected by at least one light guide 51 or an optical fiber to a light relay 50 which is located at the timepiece display 4 in the immediate vicinity of the clockwise mobile component 1 or in contact therewith.
- the invention also relates to a timepiece 100 comprising such a mechanical movement 10, and / or at least one such timepiece display 4.
- the light source 5 is either located at the timepiece display 4, or is deported out of the timepiece display 4 and inside the movement 10 in which case it is connected by at least one light guide 51 or an optical fiber to a light relay 50 which is located at the timepiece display 4 in the immediate vicinity of the mobile watch component 1 or in its contact, or is deported out of the movement 10 and inside the timepiece 100 in which case it is connected by at least one light guide 51 or an optical fiber to a light relay 50 which is located at the timepiece display 4 in the immediate vicinity of the clockwise mobile component 1 or in contact therewith.
- this timepiece 100 is a watch, and the watch component 1 is of the so-called "flat" type described above.
- the invention can be coupled with a stroboscopic device interposed on the light path between the light source and the watch component, so as to perform particular lighting.
- Structuring with stroboscopic effect according to the frequency and the wavelength of the light diffused by the source 5 or the relay 50, makes it possible to carry out an anti-counterfeiting marking or a secret signature, by structuration or masking, and which n is revealed only under certain lighting conditions.
- the slowing down of the light because of the variation of the refractive index which is linked to the variation of the stresses at heart during the contraction or the elongation of the watch component, also allows a particular authentication.
- the diffusion by a clock component 1 treated and colored at a first wavelength, with a pulsed monochrome light of another wavelength, allows a particular visualization.
- a variant of the invention rather applicable to the clocks and timepieces static, consists in its application to mobile watch component, which is not a substantially flat spring as above, but which is a coil spring.
- the display device of the watch component offered by the invention is compact and low energy consumption. It attracts the eye of the user on the visible heart of his watch or timepiece, and highlights the particularly lively character of a mechanical timepiece, saving mechanical display elements of the watch. status of a watchmaking function.
