Description

[0001] Technical Field: This invention belongs to the field of eye care within the health products industry.

[0002] Background: Among existing eye care devices, eyeglasses are the only ones that can correct eye conditions. However, wearing eyeglasses can cause pressure, discomfort, inconvenience, and many other negative experiences.

[0003] Summary of the Invention: To address the unpleasant experience of wearing glasses, this invention provides a glasses-free distance viewing device that assists in seeing text or objects clearly or partially without the need for glasses. The overall technical solution utilizes the combined use of three devices to achieve the viewing function, fulfilling the need for distance viewing without glasses: a display device, a guiding device, and a lighting device. A branch solution focuses on one device, with the others serving as auxiliary components. Functional requirements are achieved through variations in the emphasis, spatial position, and structure of the three devices, resulting in a superior visual experience. The display device comprises components carrying images or objects whose spatial position can be adjusted according to viewing needs. The guiding device, based on viewing requirements, positions lenses or components and their combinations in specific spaces, refracting or reflecting light from the displayed object to enable clear viewing of images or objects. The refraction or reflection of light, enabling the clear reading of text or objects, is based on three optical principles: first, the long-distance imaging principle of lenses; second, the refractive index of interference light produced by the spatial superposition of near-natural light is lower than that of non-interference near-natural light; and third, the interference light produced by the spatial superposition of near-natural light is more easily perceived by visual cells than non-interference near-natural light. The lighting device is of two types: one is a device equipped with a light source, positioned to facilitate the clear reading of text or objects, and capable of adjusting the brightness of the light source in real time; the other is a device that uses the light source as an information carrier, displaying text and images through a combination of light sources or after refraction through a medium.

[0004] In display device designs that primarily utilize guiding mechanisms, two types are identified: lens-guided light display devices and cylindrical stereoscopic guided light display devices. The lens-guided display device uses lenses or lens-like components as the main guiding elements. Based on the different auxiliary guiding components, it is further divided into three types. The first type, a plane mirror plus lens-guided light device, is located inside the building structure. Along its length, the operating device is placed in the middle, the display device is placed behind it, and the plane mirror is placed in front. The operating device is equipped with a lens, and the text or exhibit on the display device faces the plane mirror. The lighting device is positioned so that the light source is located in the center of the ceiling. By controlling the spatial position of the lens in front of the plane mirror through the operating device, the viewer can see the displayed text or exhibit through the lens within the plane mirror. The distance between the operating device, the plane mirror, and the display device can be adjusted according to actual needs; however, the relative positions of the three components remain unchanged. In this first type of plane mirror plus lens-guided light device, as the lens size increases, the moving operating device used to support the larger lens differs from that before the lens size was increased, but the positional relationships of the various devices and the display principle remain the same. The second type of light-guiding device uses a lens without a plane mirror. A manipulator with the lens is placed in front of the plane mirror to move and adjust the spatial position of the lens. The displayed text or objects are viewed directly through the lens in the plane mirror. An illumination device is positioned at the top, in front of the display device, to position the light source. With increasing lens size, the manipulator used to support the larger lens differs from that used for smaller lenses, but the positional relationships of the devices and the display principle remain unchanged. The third type uses a plane mirror and water to guide light. Water, as the light-transmitting substance, is contained in a container with an inlet and an outlet. The container is connected to a water pump via pipes. The pump keeps the water flowing. A transparent plastic bag containing books or other graphic media is placed in the water. An illumination device is located on the inlet side. The transparent plastic bag is equipped with a self-sealing strip with a sealing function and a support to make the plastic bag bulge. The plane mirror is placed at a certain angle on one side of the water container, and the corresponding plane mirror is placed vertically. By looking at the vertical plane mirror, the viewer can see the images and text displayed in the water in the angled plane mirror. The flowing water refracts light, and the flow of water also causes the light to overlap and meet, producing interference light, thus making the images and text clear. The cylindrical three-dimensional guiding light device is composed of an outer circle with an inner polygonal ring, with corners and sides alternately stacked. The middle part is a double-convex cylindrical structure, which is formed by trapezoidal inner polygonal outer rings with gradually increasing diameters, with corners and sides overlapping and transitioning. The interior has a brick-like structure. A display device is located near the end cap of the cylinder. A lighting device is located between the display device and the first drum-shaped protrusion, close to the cylinder wall. The light shines on the display panel, and the color of the display panel is close to the color of the cylinder wall. The regular stacking structure inside the cylinder makes the diffused light reflect more regularly, and some of the diffused light shines on the display panel, forming a spatial superposition of light of the same frequency, which interferes. The interfered light is reflected to the opening of the cylinder, allowing the viewer to see the displayed pictures, texts or objects clearly.The double convex cylinder in the middle filters out reflected light that does not follow a fixed direction, preventing it from continuing to diffusely reflect inside the cylinder and avoiding interference with regular diffuse reflection.

[0005] The display device scheme, with the display unit as its core component, is divided into two types: graphic carrier display devices and body display devices. The graphic carrier display devices are further categorized into three types based on the carrier's structure: the first type uses a single graphic carrier of different materials as a base, attaching graphics and text for display; the second type uses a composite graphic carrier display device, where the carrier has graphics attached, with the bottom attached to a substrate and the top to a transparent film; the third type combines a graphic carrier with a backplate, where the carrier has graphics attached, and a backplate with piping is placed behind the carrier display device, with the lighting device positioned between the two. The body display device is where the display device itself is the object of display; the light source from the lighting device shines through the gaps in the display device, creating a mottled, variegated pattern that produces a relaxing and comfortable visual experience.

[0006] The lighting device scheme is divided into two types: a lighting device with adjustable brightness and distance, and a multi-source dot matrix display device with adjustable dot pitch. The lighting device with adjustable brightness and distance places the display on a tray, which is guided by a servo motor and driven by a DC motor. A remote control moves the display forward or backward, a dimmer controls the brightness, and a keyboard and mouse allow for remote control of the displayed content. This can be done using wires or a remote control with accompanying circuitry. The adjustable dot matrix display device uses incandescent lamps connected to diodes as the light source for the dot matrix, thus achieving a lighting device using incandescent lamps as the dot matrix screen. By adjusting the spacing of the incandescent lamps, light interference between the point light sources is reduced, allowing for clear viewing of the graphics and text composed of the dot matrix light source from a distance. The use of incandescent lamps reduces light stimulation. Attached image description:

The other end of the auxiliary arm 70 is provided with a fixing clip 71, and a convex lens 3 is mounted on the fixing clip 71.

[0063] The working principle of the electromechanical control device 58 is as follows: the servo motor 60 controls the direction of chassis movement, the motor 63 drives the chassis to move, causing the device to shift as a whole, the motor 63 drives the support arm, the servo motor 60 controls the angle of the swing arm, and through the control of the rotation angle of the motor 63 and multiple servo motors 60 located above the chassis, the swing arms change spatial position and combine into shape, so as to swing the convex lens 3 to the required spatial position.

[0064] The control device 255 can specifically be a lever-type control device 88, which includes a bracket 89, a turntable 90, a support ring 93, a rod 92, and a clamping block 94.

The guidance of the convex lens 3 ensures that the emitted light does not simply return along the original path. Some of the light is superimposed after several refractions and reflections, and some changes direction after several superpositions. Those that change direction and are seen are the positions where the displayed text or objects are clearly visible, either partially or largely.

Sealant is applied to the joined periphery, a transparent liquid is injected into the container, and the cap 125 is tightened.

[0072] Another embodiment of the concave lens 120 is a concave lens assembly 126, comprising a small-diameter arc-shaped concave shell 127 and a large-diameter arc-shaped concave shell 128, characterized in that, except for the arc-shaped concave structure, the remaining structure and assembly method are the same as those of the aforementioned convex lens assembly 121.

[0073] The working principle of a lens-guided naked-eye distance vision device 104 is as follows: Based on the distance imaging law of the display component, when the convex lens 3 is placed in front of the display board 4, a person views the image refracted by the convex lens 3 from a distance. The distance between the convex lens 3 and the display board 4, and between the convex lens 3 and the person, is adjusted until the image or text on the display board 4, whether upright or reversed, can be clearly seen. The convex-concave lens guiding display device 119 uses the convex lens 3 and the concave lens 119 to guide light refraction. The distance between the convex lens 3, the concave lens 119, and the display board 4 is adjusted until the image or text on the display board 4, whether upright or reversed, can be clearly seen.

[0075] The working principle of a plane mirror and water-guided naked-eye distance vision device is as follows: the flowing water causes the incident light and reflected light to converge and overlap. The light emitted by the illumination device 127 is incident on the text in the book in the flowing water. The light is reflected and refracted by the flowing water onto the tilted plane mirror 125, which displays the text in reverse. The light is then reflected onto the upright plane mirror 126, which displays the text in an upright position. The relative positions of the various devices are adjusted so that the clear text presented by the converged and overlapping light can be viewed.

The front straight cylinder 149 is characterized by being composed of an end cap 163, a first ring 157, and an overlapping ring 158. The end cap 156 is a circular plate structure with four countersunk holes 165 symmetrically arranged around its circumference. The first ring 157 is an outer circle with an inner polygon, and eight threaded through holes 169 symmetrically arranged around its circumference. The overlapping ring 158 is positioned diagonally opposite each other; when stacked diagonally, the countersunk holes 165 correspond to the threaded holes 167. A bolt 2 is also included. Bolt 256 passes through the countersunk hole of end cap 163 and connects to the threaded hole of first ring 157. Overlapping ring 158 is an outer circle with an inner polygon, with 8 countersunk holes 168 and 8 threaded holes 167, all double-symmetrical. Overlapping rings 158 are placed diagonally opposite to the first ring. Bolt 256 passes through the countersunk hole of overlapping ring 158 and connects to the threaded hole of first ring 157. The second overlapping ring 158 is placed diagonally opposite to the first overlapping ring 158, and its countersunk holes and threaded holes also correspond simultaneously. Bolt 256 connects the two overlapping rings, and so on, until the overlap is completed at the front straight cylinder 149. Lighting device 1 48 is located at the rear end of the front straight cylinder 149, and the diameter of all the inner circles of the front straight cylinder 149 is 0.86 meters. The front drum 150 is composed of an expansion ring 159 and a frustum expansion ring 160. The expansion ring 159 is identical in structure except that its inner diameter is larger than that of the overlapping ring 158. The cross-section of the frustum expansion ring 160 is an outer circle with an inner polygon. It has eight countersunk holes 165 symmetrically located on the inner polygonal circumferential surface or the outer conical surface, and eight threaded holes 167 symmetrically located on the end face of the frustum. The front drum 150 has a front small drum 156, which is composed of expansion rings 159. The front drum 150 is the largest... The large inscribed circle diameter is 1.5 meters; the middle straight cylinder 151 is composed of a narrow ring 161 and a wide ring 162. The structure of the narrow ring 161 is the same as that of the overlapping ring 158, and the structure of the wide ring 162 is the same as that of the narrow ring 161, with a length approximately four times that of the narrow ring 161. The total inscribed circle diameter of the middle straight cylinder 151 is 1.15 meters; the rear drum 152, except for the front small drum 156, has the same structure as the front drum 150. The rear straight cylinder 153 is composed of a narrow ring 164, a wide ring 165, and a port ring 166. The inner diameter of the rear straight cylinder 153 is 0.95 meters, which is larger than that of the front straight cylinder 149 but smaller than that of the middle straight cylinder 151. The inner diameter refers to the inscribed circle diameter of the inner polygon. Bolts 164 pass through the countersunk holes 165 of the support 154 and are connected to the front straight cylinder 149 and the rear straight cylinder 153 respectively. The cylindrical three-dimensional guiding and lighting device 155 has a total length of 12.8 meters and its inner surface is brown.

[0077] The working principle of a cylindrical stereoscopic guided naked-eye distance viewer 155 is as follows: the light from the light source shining on the display object is diffusely reflected towards the exit in a certain range according to a certain pattern. The light that converges in the space produces interference, thereby achieving the purpose of clear visibility. Some of the light that is not directed towards the exit is filtered out in the space between the front and rear drums to reduce interference with the light directed towards the exit.

[0078] A naked-eye distance viewing device 171 for displaying images and text includes: a bracket 172, a clip 174, wax paper 173, a multi-headed pen 193, and an illumination device 187. The clip 174 is connected to the bracket 172. The wax paper 173 is semi-transparent, used for printing, preferably blue. The multi-headed pen 194 is an accessory to the wax paper 173, including a pen tip 192, a spring 190, an inner locking cover 189, an outer locking cover 190, and a pen body 194. The pen body 194 has multiple holes, and the spring 190 is installed in the holes. The pen tip 192, which has a shoulder, presses against the spring 190. The pen tip 192 passes through the multiple holes in the inner locking cover 189, and the inner locking cover 189 is threadedly connected to the outer locking cover 190. A multi-headed pen 193 writes text on wax paper 173. A clip holds the wax paper 173 with the text written on it and hangs it on a bracket. An lighting device 187 with a light source 186 is placed behind the bracket 172. The lighting device 187 is equipped with a dimmer 188. The light source 186 is an incandescent lamp.

[0079] Another embodiment of waxed paper 173 is cloth 193, cloth 196, with a colored background 194 and white line graphics 195, preferably a blue background, the white lines being the cloth's own color, not an attached color.

[0080] Another embodiment of waxed paper 173 is a screen 197, which has the same shape and structure as the screen used for doors and windows. Its characteristic is that the material can be plastic or metal, and the matching tool is a brush or paintbrush. The brush is dipped in ink to write the text 198 which is attached to the stripes of the screen 197.

[0081] The principle of the naked-eye distance vision device 171, as illustrated in the illustrations, is as follows: light shines from the back onto the wax paper 173, cloth 193, and mesh 197. Some of the light passes through the text on the wax paper, through the white of the cloth, and through the square holes of the mesh, making it easier to be perceived visually.

[0082] A multi-layered, naked-eye, distance viewing device 199 includes: a support 204, a transparent film 203, a display film 200, and a base plate 201.

The display film 200 is adhered to the base plate 201, and the transparent film 203 is adhered to the display film 200. The film can be adhered entirely with transparent adhesive or directly attached, with transparent tape used around the edges. The adhered base plate is then installed in the guide groove 202 of the support. A lighting device 187 is placed in front of the support 204, and the lighting device 187 is equipped with a light source 186 and a dimmer 188.

[0083] The principle of the multi-layered structure graphic display naked-eye distance viewer 199 is that the light reflected from the light background is like mirror reflection. Most of the light is reflected in one direction. If you are not looking at the reflection path, the perception is not obvious. The light yellow and brown backgrounds are diffuse reflections, which are easily perceived. Especially when the path boundaries of the two types of reflected light are obvious, the light interference at the boundary of the graphic is reduced, making the graphic clearly visible and more clearly perceived.

[0084] A naked-eye distance viewer 205 with a rear-mounted tube plate and graphic display includes: a mesh screen 197, a bracket 209, an illumination device 187, a reflector tube 207, a back plate 206, and a bracket 208. The back plate 206 is mounted on the bracket 208, and the back plate 206 is covered with equally spaced parallel reflector tubes 207. The reflector tubes 207 are coated bright metal tubes, and can be connected by welding, bonding, or adding external fixing strips. Alternatively, corrugated plates can be used to replace the back plate 206 and reflector tube 207 assembly. The illumination device 187 is placed to the side front of the bracket 208, and the bracket 209 is placed in front of the illumination device 187. The mesh screen 197 is mounted on the bracket 209, and text 198 is attached to the mesh screen 197.

[0085] The principle of the naked-eye long-distance viewing device 205 for the rear lining pipe plate graphic display is: parallel and equidistant focused reflected light is easily perceived by the eyes. The mesh of the gauze 197 evenly separates the light, making the mesh lines easily perceived by the eyes. The combined use of the two easily perceived components makes the graphics and text easier to see.

[0086] A tree-shaped body-mounted naked-eye distance viewing device 211 includes: a base 147, a main rod 148, support rods 149, and leaf-shaped pieces 150.

[0091] The principle of the naked-eye distance viewer 226, which adjusts the brightness and distance of the display from a distance, is to adjust the distance of the display, the display content, the size and brightness of the display content in a timely manner to meet the needs of clear viewing.

[0092] A detachable, adjustable dot-pitch incandescent lamp matrix naked-eye distance viewing device 236 includes: a bracket 250, an incandescent lamp 238, a diode 240, a lamp holder 239, a support mesh 241, a negative electrode wire 242, a positive electrode wire 243, a controller 247, a low-voltage DC power supply 248, a brightness adjustment potentiometer 237, and a remote control 249. The incandescent lamp 238 is mounted on the dot-pitch lamp holder 239, and the connection points of the incandescent lamp 238 and the lamp holder 239... The connection points are correspondingly in contact. The positive and negative wires connected to the connection points of the lamp holder 239 pass through the bottom of the lamp holder 239. The positive wire 254 is connected to the negative pin of the diode 240. The positive pin of the diode 240 is connected to the positive wire 243. The negative wire 253 is connected to the negative wire 242. The positive wire 243 and the negative wire 242 are fixed together by screws between the clamping block 252 and the lamp holder 239. The rope buckle 251 connects the negative wire 242 and the positive wire 243 to the support. The grid strips of the support net 241 are wound and fixed. The rope buckle 251 is made of metal or fiber. The support net 241 is a mesh made of metal or plastic. The connection parts and methods of each point in the dot matrix are the same. The distance between the lamp holders 239 can be disassembled, adjusted, and re-fixed according to actual needs. The support net 241 is installed on the bracket 250. The edge can be fixed to the frame with a pressure strip. The positive wire 243 and negative wire 242 converge at the frame of the bracket and are grouped and connected to the row seat 244 according to their corresponding positions. The wire harness 246 of the row pin 245 corresponding to the row seat 244 is connected to the output port of the controller 247. The input port of the controller 247 is connected to the output port of the low voltage DC power supply 248. The input port of the low voltage DC power supply 248 is connected to the brightness adjustment potentiometer 237 and the AC 220V power plug. The remote control 249 is model 315. The matching remote control receiver motherboard is installed in the controller and controls the opening and closing of the main chip AT89C52. Figure 45 The circuit schematic shows that the outputs of the AT89C52 are connected to the data driver chip 74HC595 and the scan driver chip 74HC138, respectively. The output of the 74HC595 is connected to the current-limiting resistor R = 200Ω, and then to the row corresponding header 244. The 74HC138 is connected to the resistor R = 1500Ω and the PNP... s After connecting 8550, connect it to the corresponding row seat 244.

[0093] The principle of the adjustable dot pitch incandescent lamp dot matrix naked-eye long-distance viewer 236 is as follows: when a row line is at a high level and a column line is at a low level, the intersection of the row and column is lit. When a row line is at a low level, regardless of the column line, the corresponding dots are all dark. The display is achieved by scanning line by line at a certain frequency. Data is continuously input and displayed. As long as the scanning frequency is high enough, due to the visual persistence effect of the human eye, complete text or graphic information can be seen. The main feature of the adjustable dot pitch incandescent lamp dot matrix display device 236 is that the distance of the incandescent lamps can be adjusted separately, thereby eliminating the interference of edge light caused by close distance between light sources. This makes the information and graphics displayed clearly when viewed at a distance. The light source is incandescent lamp instead of LED lamp to make the light source closer to natural light, which is more comfortable for vision and less likely to cause stimulation and fatigue. The brightness of the incandescent lamp can be adjusted in time to achieve a visual effect that allows for clear viewing at a distance without stimulating the eyes.
