Definitions
- WO 2004/015658 discloses a backlit display comprising a front face having at least one transparent region, and at least one mirror arranged at the rear of the front face and oriented so as to reflect a vertical incident external light in the direction of the front, to ensure the backlight of it.
- WO 2008/110881 discloses a bottle or bottle stopper comprising a sealed housing and a reflective object arranged inside the housing, the reflective object being oriented to receive a vertical incident light vertically and return a light reflected on a transparent region of the object, to ensure the backlight thereof.
- the present invention proceeds from the idea of implementing a similar principle of ambient light collection in the field of small decorative decorative objects and in particular in the field of jewelery, to produce objects that offer a surprising effect of blazing or who seem enlightened from the inside.
- the present invention more particularly relates to a portable decorative object or intended to be worn on oneself, and / or weighing less than 20 grams, devoid of a light source, comprising a transparent piece having an upper face, wherein the transparent piece comprises at least one reflective inclined edge oriented to receive incident ambient light perpendicular to the upper face of the transparent piece, the inclined edge being oriented to return to the interior of the room transparent perpendicular incident light, the object comprising a decorative region illuminated by the light reflected by the inclined edge.
- the inclined edge has an angle of 45 ° to a degree relative to the upper face of the transparent part.
- the decorative region comprises an etching performed on a lower face of the transparent part, revealing a relief shape inside the transparent part.
- the decorative region comprises at least one of the following elements: an object included in the transparent part, combinations of transparent materials of different colors, a colored region included in the transparent part, or bubbles of air or gas trapped from the transparent piece.
- the transparent piece is a plate comprising a rear face parallel to its front face.
- the transparent piece is made of a mineral or organic glass.
- the reflective inclined edge comprises a layer of a reflective material.
- the object is a jewel.
- the object belongs to the group of objects comprising: a watch glass, a cufflink, a ballpoint pen, a decoration of a branch of spectacles.
- FIG. 1 is a sectional view of an embodiment of a decorative object according to the invention
- FIG. 2 shows light paths in the decorative object
- FIG. 3 is a view from above of a first variant embodiment of the object of FIG. 1,
- FIG. 4 is a sectional view of a second alternative embodiment of the object of FIG. 1,
- FIG. 5 is a sectional view of a third variant embodiment of the decorative object of FIG. 1, and
- FIG. 6 is a sectional view of a fourth variant of the decorative object of Figure 1.
- Figure 1 is a sectional view of an embodiment of a decorative object according to the invention.
- the object is shown in section and comprises a wafer 1 in at least one transparent material, such as mineral or organic glass.
- transparent material such as mineral or organic glass.
- mineral or organic glass is meant any type of transparent material commonly used in the industry for making glasses or the like, including acrylic, polycarbonate, sapphire, etc. glasses.
- the wafer 1 comprises a front face 2, a rear face 3 substantially parallel to the front face 2, at least one inclined edge 4 covered with a reflecting material 5, and a decorative region 6 located inside the wafer.
- the inclined edge 4 here has an angle A1 of the order of 45 ° relative to the upper face of the wafer, more or less a degree.
- the reflective material 5 is for example a thin layer of chromium deposited in the vapor phase (PVD).
- the thickness of the wafer 1 is a function of the intended application, and may be of the order of a few millimeters, for example from 1 to 5 mm.
- the decorative region here comprises an etched region 6 on the rear face of the wafer 1, revealing inside the wafer hollow patterns which extend in the thickness thereof. These patterns extend over a fraction of the thickness of the wafer, for example between 2 and 5 tenths of this thickness.
- FIG. 2 represents an exemplary path of a vertical incident ambient light 100 perpendicular to the front face 2, the wafer 1 being assumed to be arranged horizontally.
- the light 100 is reflected on the inner face of the inclined edge 4, thanks to the material 5, to form a reflected light 101 which is returned to the inside of the wafer, here in a direction parallel to the front face 2, and which illuminates the engraving 6.
- the light is preferably a matte (unpolished) etching. It can be performed by a mechanical process such as sanding or microbilling.
- the decorative region 6 may comprise an object included in the wafer, combinations of transparent materials of different colors, air bubbles or gases trapped in the wafer, etc.
- the reflective material may comprise a combination of colored chromes, to introduce color variations in the light it reflects, or other reflective materials such as silver or gold.
- the plate 1 seen from above can be of generally circular shape, as shown in FIG. 3, or triangular, parallelepipedal, polygonal, etc. If she is not circular, it has several edges. Each of these edges can then be provided inclined and reflective, or only part of them. The angle of inclination of each edge may vary to illuminate different regions of the wafer.
- the wafer 1 is surrounded by a frame 8 of circular, triangular, parallelepipedal or polygonal adapted to that of the wafer.
- the frame may be made of metal, of mineral or organic glass, and has an inclined inner face that matches the outer shape of the wafer and covers the inclined edge 4.
- the wafer 1 and held by the frame 4 is here mounted on a support 9 , which can be hollow or full.
- Figure 5 shows a transparent piece 1 of complex shape forming an alternative embodiment of the wafer 1 (Figure 1) including the initial form thereof, as shown by dashed lines.
- the piece has a rear face 3 'of non-planar surface, obtained for example by etching.
- the piece also comprises another edge 11, in the extension of the edge 4, which forms an edge with the rear face 3 '.
- the etched decorative region 6 is present in the center of the rear face 3 ', and is here of the same shape as that of the wafer 1
- Fig. 6 shows a transparent part 1 "also forming an alternative embodiment of the wafer 1 (Fig. 1) including the initial form thereof as shown by dotted lines. of polyhedral type and has a rear portion of complex shape comprising several faces 12, 13, 14, the face 12 being in the extension of the edge 4 of the wafer 1, the face 14 forming the rear face of the piece 1 ". 4 itself forms a face of the piece 1 "and is no longer a board edge itself.
- the decorative region comprises bubbles 6 'of air or gas trapped in the material forming the part, on which an incident light 100 is reflected, the reflected light 101 showing the decorative region as illuminated from the inside.
- the upper face of the object could also be non-planar.
- a decorative object according to the invention is portable and intended to be worn on oneself or with oneself. In other embodiments, a decorative object according to the invention weighs less than 20 grams including the decorative region.
- the present invention is particularly applicable to the production of jewelry (ring, pendant, earring, etc.), jewelry parts, or portable decorative objects or portable decorative objects parts having in addition to a technical function a decorative function similar to that of jewelry, such as: watch glass, cufflink or cufflink decoration, top of a ballpoint pen, decoration of a branch of glasses ...
- An application to mobile phone shells can also be considered.
- the transparent plate ⁇ , ⁇ ', ⁇ " can also be made of a precious or semi-precious stone, even of plastic material, such as polymethyl methacrylate.
- the angle of 45 ° may vary more than one degree depending on the location of the inner part of the object to be illuminated, and may for example be between 40 and 50 °.
