Technical Field

[0003] This invention relates to the field of light reflection, and more particularly to a light reflection device for a grooved surface. Background Technology

[0004] When using a material in a product or structure, its ability to reflect or absorb light is usually taken into consideration. For example, in products that require light transmission (such as equipment using lasers), different types of highly reflective glass and mirrors are often used. Highly reflective materials are also common in safety products, such as reflectors on vehicles or reflective fabrics in clothing. When light reflection is not required, materials that readily absorb light can be used. For example, light-absorbing marker paint can be used on roads to prevent glare for drivers. Furthermore, light-absorbing or reflective materials are also frequently used in decorative elements, such as outdoor sculptures. The Cloud Gate sculpture in Chicago is designed to reflect the distorted skyline of Chicago.

[0005] However, in many cases, we desire better control over a material's ability to reflect light, the direction of light reflection, or other characteristics of light reflection. While the ability to reflect or guide light can be controlled by positioning or orienting a mirror or other highly reflective material at a desired angle, repositioning these materials to achieve different reflection modes may require mechanical devices such as supports, actuators, or similar repositioning mechanisms. Even so, some reflective materials may not be suitable for all situations. For example, while glass mirrors are reflective, they are also highly fragile and therefore unsuitable for certain environments.

[0006] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

At least one light source emits light on the first surface and the second surface, wherein when the orientation of light emitted onto the first surface and the second surface is changed by moving the first surface and the second surface or by moving at least one of the light sources, the first groove on the first surface and the second groove on the second surface independently reflect the emitted light.

[0008] This invention provides a grooved surface light reflection device.

[0019] To provide greater control over light reflection, such as Figure 1 As shown, the present invention provides a grooved surface light reflecting device 10. The grooved surface light reflecting device 10, referred to herein simply as device 10, includes: a first surface 20 having a first groove 22, and a second surface 30 having a second groove 32. The second groove 32 of the second surface 30 differs from the first groove 22 of the first surface 20 in that the angle shape of the second groove 32 is different from that of the first groove 22. The device 10 may also be provided with any other number of surfaces having grooves. The device 10 provides at least one light source 40, which emits light 42 on the first surface 20 and the second surface 30. As the direction of the emitted light 42 changes relative to the first surface 20 and the second surface 30, the first groove 22 of the first surface 20 or the second groove 32 of the second surface 30 independently reflects light 42A or light 42B.

[0020] Specifically, the device 10 can control the independent reflection of light from different surfaces based on the first groove 22 and the second groove 32 at different angles within the surface. For example... Figure 1 As shown, the first surface 20 and the second surface 30 can be two of a plurality of surfaces located on the central support, base, or plate 12. While the application of the first surface 20 and the second surface 30 has been discussed in this invention, it should be noted that the device 10 can include a plurality of grooved surfaces, each of which can have different or similar grooves formed. For example, as... Figure 1 As shown, plate 12 has six different groove surfaces, each groove surface being disposed within a portion 14 of plate 12, such that the positions of the first groove 22 and the second groove 32 at different angles are different from each other. In other examples, the groove surfaces may be in different angular orientations, for example, the first groove 22 and the second groove 32 may have different spatial orientations on the plane of plate 12. For instance, the first groove 22 and the second groove 32 may not be parallel to each other. It should also be noted that the first groove 22 and the second groove 32 may be located in positions where portions 14 are completely adjacent to each other or even overlap each other.

[0021] The plate 12 may be a structure with a mounting surface, which is typically planar, and the recessed surfaces (the first surface 20 and the second surface 30) may be attached to or formed on the mounting surface. The plate 12 may be of any size or shape, such as a large circular size with a diameter of 1-10 feet, or a small non-circular size with a width of less than 1 foot. The plate 12 may be mounted on a mounting device, such as a bracket or stand, for example, a bracket that allows the plate 12 to rotate or otherwise move. Therefore, the bracket or stand may utilize any mechanical or electromechanical device to control the movement of the plate 12, such as bearings, rotary joints, servo motors, actuators, belts, pulleys, gears, or any other device.

[0022] The groove surfaces (first surface 20 and second surface 30) can be made of various materials. For example, the groove surfaces (first surface 20 and second surface 30) are typically made of a metal with sufficient ductility. Metal materials may include copper, bronze, steel, gold, silver, or any other type of metal or metal compound. Different metals can also be plated onto the metal surfaces (first surface 20 and second surface 30) using electroplating or sputtering coating processes, allowing the use of inexpensive metals as the primary substrate while using more expensive or more reflective metals (such as gold or silver) for light reflection. Other materials can also be used for the groove surfaces, including plastics, glass, resin-based materials, polymers, or any other type of material. The materials used can be selected based on the intended use and design of the device. Furthermore, it should be noted that the etched grooves are delicate and difficult to clean if they become dirty. Therefore, in order to prevent light reflection from being contaminated or obstructed, the surfaces of the grooves (the first surface 20 and the second surface 30) as well as the first groove 22 and the second groove 32 can be sealed under a transparent protective coating (e.g., paint, polyurethane or similar fully transparent or semi-transparent protective coating). The coating can fill all or part of the first groove 22 and the second groove 32, but still allow light to be reflected in the first groove 22 and the second groove 32.

[0023] Figures 2A-2D yes Figure 1 A schematic diagram of the groove surface in the groove surface light reflection device of Embodiment 1 of the present invention. (See attached diagram.) Figures 1-2D As shown, the first groove 22 of the first surface 20 and the second groove 32 of the second surface 30 are formed within the surface and descend into the material. The first groove 22 and the second groove 32 have variable angular dimensions, such that one or more sidewalls 24 of the first groove 22 have a specific angular position relative to the basic planar shape of the first surface 20, on which the first groove 22 is formed; similarly, one or more sidewalls 34 of the second groove 32 have a specific angular position relative to the basic planar shape of the second surface 30, on which the second groove 32 is formed. For example, as... Figure 2A As shown, the first groove 22 of the first surface 20 is provided with a first sidewall 24, as indicated by arrow 26. The angle between the first sidewall 24 and the first surface 20 extending therefrom is between 90° and 135°. Figure 2BAs shown, the second sidewall 34 of the second groove 32 can form a larger angle 36 with the second surface 30 extending therefrom, for example, greater than 135°. However, it should be noted that the first groove 22 and the second groove 32 within the first surface 20 and the second surface 30 can have angles of any size, for example less than 90°, between 90° and 135°, and / or greater than 135°, all of which are within the scope of the present invention. By changing the angular shape of the first groove 22 and the second groove 32, the depth of the first groove 22 and the second groove 32 can be changed, both of which affect the reflection of light from the first sidewall 24 of the first groove 22 and from the second sidewall 34 of the second groove 32.

[0024] In addition, such as Figure 2C-2D As shown, the number of the first groove 22 per unit area on the first surface 20 and the number of the second groove 32 per unit area on the second surface 30 can vary, such that... Figure 2C The number of grooves per unit area on the grooved surface (first surface 20) is less than Figure 2D The groove surface 30 (the second surface 30) is understood to be the unit density of the grooves. It should also be noted that the dimensions of the first groove 22 and the second groove 32 within a given unit length or unit area can vary without changing the number of the first grooves 22 and the second grooves 32 themselves. For example, by providing more or less space between the first grooves 22 and more or less space between the second grooves 32 on the first surface 20. For example, by enlarging the first opening of the first groove 22, which is defined between the first sidewall 24 and the first surface 20; and by enlarging the second opening of the second groove 23, which is defined between the second sidewall 34 and the second surface 30. To illustrate the different grooves per unit area, Figure 3A Examples include surfaces with a high number of grooves per unit area, such as the first surface 20, which is one square inch. Figure 3B The example illustrates two surfaces with a small number of grooves per unit area. Furthermore, as shown, the first groove 22 and the second groove 32 can be symmetrical, asymmetrical, have flat sides, have curved sides, or have any other variation. Similarly, the first groove 22 and the second groove 32, which intersect each other, can create a crosshair pattern, allowing a single area to reflect light simultaneously in different directions.

[0025] Furthermore, the positions of the first groove 22 and the second groove 32 can be changed. For example, as Figure 1As shown, the first groove 22 of the first surface 20 extends along a linear direction, while the second groove 32 of the second surface 30 extends along a different linear direction. The first surface 20 and the second surface 30 may also have the first groove 22 and the second groove 32 located in different linear directions within the same surface (the first surface 20 and the second surface 30). For example, the directions of the first groove 22 and the second groove 32 within the same surface (the first surface 20 and the second surface 30) can be alternated. For example, as... Figure 3B The groove pattern exemplified in the first part 50, when columns or rows of the first groove 22 and the second groove 32 are formed in the first surface 20 and the second surface 30, has alternating groove directions between adjacent columns or rows. In another example, such as Figure 3B The groove pattern exemplified in Part 2, 52, wherein the first groove 22 and the second groove 32 may be positioned on a circular surface (the first surface 20 and the second surface 30), wherein each groove (the first groove 22 and the second groove 32) is positioned along a radial path formed substantially tangentially within the circular surface (the first surface 20 and the second surface 30).

[0026] In addition to having the first groove 22 and the second groove 32 within a row or column, the first groove 22 and the second groove 32 can also be oriented within a linear or curved path; this concept is called path blinking. For example, Figures 4A-4B This is a schematic diagram of the groove pattern of the groove surface light reflection device in Embodiment 1 of the present invention, as shown below. Figures 4A-4B As shown, the curved path of the straight line has different segments, namely, the first segment 54A, the second segment 54B, the third segment 54C, and the fourth segment 54D, wherein each of the first segment 54A, the second segment 54B, the third segment 54C, and the fourth segment 54D has a plurality of the first groove 22 and the second groove 32.

[0027] Although the previous examples used a region or section with parallel grooves, such that all the grooves within that region reflect light simultaneously, Figures 4A-4BThe path flickering example uses parallel grooves within specific segments 54A, 54B, 54C, and 54D, such that segments 54A, 54B, 54C, and 54D reflect light at a given point in time. When multiple segments 54A, 54B, 54C, and 54D are positioned adjacent to each other, each segment has a different angle, a first angle A1, a second angle A2, a third angle A3, and a fourth angle A4. Light may be reflected from the first groove 22 and the second groove 32 at different time intervals. Therefore, as the light moves or when the surface containing the first groove 22 and the second groove 32 moves relative to the light, the reflected light moves along any path or curve of the segments 54A, 54B, 54C, and 54D. The path flashing, divided into first segment 54A, second segment 54B, third segment 54C, and fourth segment 54D, is possible for any curved or straight path, and each of the first segment 54A, second segment 54B, third segment 54C, and fourth segment 54D is filled with the first groove 22 and the second groove 32, the first groove 22 and the second groove 32 having different angles than the first groove 22 and the second groove 32 of the previous segment (first segment 54A, second segment 54B, third segment 54C, and fourth segment 54D). Typically, the changes between the angles of the first segment 54A, second segment 54B, third segment 54C, and fourth segment 54D—first angle A1, second angle A2, third angle A3, and fourth angle A4—can be incremental, making the light appear to move or travel along the path.

[0028] Figure 4A This is a schematic diagram of path blinking for the first segment 54A, the second segment 54B, the third segment 54C, and the fourth segment 54D. Each segment has a first angle A1, a second angle A2, a third angle A3, and a fourth angle A4 at different angles of the first groove 22 and the second groove 32. In fact, path blinking can also be... Figure 4B As shown, Figure 4B Examples include numerous shortened segments 54A, 54B, 54C, and 54D, where the angular position variation between the first groove 22 and the second groove 32 within each segment 54A, 54B, 54C, and 54D is incremental. In practical applications, when a path with multiple segments 54A, 54B, 54C, and 54D rotates relative to one or more light sources 40 emitting light 42, if the light source 40 moves relative to the first groove 22 and the second groove 32, the reflected light will visually appear to travel along the path, as indicated by dashed arrow 56.

[0029] For any embodiment of the invention, the first groove 22 can be formed in the first surface 20 and the second groove 32 in the second surface 30 by any known technique. In one embodiment, the first groove 22 is formed in the first surface 20 using an inscription technique and the second groove 32 is formed in the second surface 30 using an inscription technique, i.e., by moving a strong tool through the first surface 20 and the second surface 30 with a downward force. In another embodiment, a computer numerical control (CNC) machine tool can be used to precisely and efficiently drag a diamond-tipped engraving drill bit across the surface to form the first groove 22 and the second groove 32. When using a CNC machine tool, software can be used to generate a specific design with any number of the first surfaces 20 and the second surfaces 30, thereby controlling or recommending a specific type of the first groove 22 in the first surface 20 and a specific type of the second groove 32 in the second surface 30. The software can communicate with the CNC machine tool, which receives geometric code (g-code) to control the engraving movement of the CNC machine tool. Other processes, such as chemical etching, stamping, molding, or similar techniques, can also be used.

[0030] As previously described, the angular shapes of the first groove 22 and the second groove 32 allow light to be reflected from the groove surfaces (first surface 20 and second surface 30) in different directions. Thus, by placing a certain number of first grooves 22 with the same angular shape within a first surface 20 and a second number of second grooves 32 with the same angular shape within a second surface 30, light can be reflected in different directions from two or more surfaces. Different lighting effects can be produced when the first surface 20 and the second surface 30 move or rotate, or when the light source 40 moves or rotates relative to the first surface 20 and the second surface 30. For example, by changing the angles between the light source 40, the first surface 20 and the second surface 30, and the observer, different portions of the first surface 20 and the second surface 30 can appear to emit light. In other words, light from the light source 40 can be reflected at different angles on different first surfaces 20 and second surfaces 30, such that different beams of light are reflected into the observer's eye based on the specific angle of the light source 40 relative to the first surface 20 and the second surface 30, as well as based on the characteristics of the first groove 22 in the first surface 20 and the second groove 32 in the second surface 30.

[0031] In a preferred embodiment, the first surface 20 and the second surface 30 are mounted on a dynamic structure (e.g., a rotatable plate) that rotates relative to the stationary light source 40, such that as the first surface 20 and the second surface 30 move, an observer sees different light reflections. The light appears to dance on the first surface 20 and the second surface 30 in a pleasing manner, creating an animated effect. The first surface 20 and the second surface 30 can be rotated using any type of mechanical or electromechanical device, such as an electromagnetic motor, blades powered by wind or water flow, or any other device capable of inducing rotational motion. A similar effect can be achieved by keeping the first surface 20 and the second surface 30 stationary and moving the light source 40 relative to them. Figure 5 This is an illustration of the device 10 as a dynamic structure, wherein the first surface 20 and the second surface 30 rotate relative to the light source 40 emitting light 42. As shown, light reflection on the different surfaces (the first surface 20 and the second surface 30) creates brighter and darker areas on the device 10. As the device 10 rotates, for example, by fixing the first surface 20 and the second surface 30 using a rotating bracket 48, the brighter and darker areas move from the respective surfaces (the first surface 20 and the second surface 30) to produce an illumination animation. The illumination animation can include various types, such as spiral patterns, radial movement from the center to the outer edge, scattered light patterns where light moves between the first surface 20 and the second surface 30 in a more abstract pattern, or any other pattern. The resulting effect can be displayed as a dynamic light mosaic.

[0032] Furthermore, it can display non-abstract patterns, such as photographs, text, designs, symbols, or other recognizable elements. For example, motion can be programmed to have specific behaviors that affect animation, such as mimicking the movement of a pendulum, providing directional movement instructions for vehicle or pedestrian traffic, or other similar actions.

[0033] Furthermore, other effects can be produced by changing other physical parameters of the first surface 20 and the second surface 30. For example, the first surface 20 and the second surface 30 can be mounted at an angle or tilt when rotated, or without any rotation, so that light is reflected at an angle. Different first surfaces 20 and second surfaces 30 can also be configured so that they can move independently and their movement or illumination can be coordinated.

[0034] In another example, such as Figure 6As shown, multiple light sources 40 can be used, and these light sources or ambient light sources can be positioned or arranged to illuminate the first surface 20 and the second surface 30. When multiple light sources are used, the color of the light can be changed to create different color visual effects. By placing different light sources at different angles, multiple surfaces of the device (the first surface 20 and the second surface 30) can be illuminated. When this happens, one color illuminates some surfaces (the first surface 20 and the second surface 30), while different colors illuminate other surfaces. Improvements that are readily apparent to those skilled in the art can be made by moving the inner surfaces (the first surface 20 and the second surface 30) relative to the lighting, for example by rotating the first surface 20 and the second surface 30 on a rotating bracket 48, and / or moving the light source relative to the inner surfaces (the first surface 20 and the second surface 30), or by moving the first surface 20 and the second surface 30 and the light source simultaneously, and are all included within the scope of this invention. It should be noted that further effects can be produced by changing the rotational or moving speed of the first surface 20 and the second surface 30, pulsed with light of different colors at frequencies corresponding to the rotational speeds of the first surface 20 and the second surface 30, or by the movement of the first surface 20 and the second surface 30. Alternatively, the lighting or lighting color can be determined by interactive input, such as sound, musical beats, nearby motion, or other input from the environment.

[0035] In addition to large flat metal sheets, grooves can also be formed within the metal surface of an object. For example, grooves can be formed in works of art such as sculptures, architectural structures in buildings, and jewelry such as earrings, necklaces, bracelets, rings, and badges, where the movement of the user, observer, and light can produce an appearance of light emission, motion, or animated patterns. These jewelry items can be made of metal or other materials such as plastic or glass. Figures 7A-7B This is a schematic diagram of the groove surface light reflection device in embodiment 1 of the present invention applied to jewelry. Figure 7A As shown, an earring may have one or more of the first surface 20, and the jewelry surface 20 has one or more portions, each portion containing a number of grooves (the first groove 22 and the second groove 32). When the wearer moves, the first surface 20 on the earring will move, thereby changing the light reflection on the first groove 22 and the second groove 32. Similarly, in Figure 7BIn this context, the jewelry item is a bracelet having a first surface 20 including the first groove 22, from which light is reflected in various directions when the user moves their wrist. Other jewelry items may include necklaces, pendants, brooches, body jewelry, or any other type of jewelry or fashion accessory. Using a grooved surface on jewelry items can be effective during recreational activities with significant lighting, such as music festivals, parties, dances, clubs, sporting events, or any other environment with abundant lighting.

[0036] The device 10 can also be used in the form of marking or communication, for example, by using light to indicate different visual or text messages relative to the user and the surface in different orientations. For example, a stop sign with a grooved surface can be animated to indicate that a train is approaching. Therefore, any use of the device 10, whether decorative, practical, or a combination thereof, is included within the scope of this invention, including but not limited to security purposes, communication, ID badges, safety, entertainment, education, industry, or others.
