Description

Technical Field

[0001] This invention belongs to the field of aiming scope technology, and particularly relates to a multi-pattern differentiation graphic illumination system and device for aiming scopes. Background Technology

[0002] In the field of scopes, the pattern is the core of the aiming reference, and its display effect directly affects aiming accuracy and environmental adaptability. Traditional scopes mostly have fixed pattern designs, usually using a single graphic structure and fixed color, which can only meet the aiming needs of specific scenarios and cannot adapt to complex and changing usage environments (such as strong light, low light, fog, etc.) and different target types (such as long-range accurate aiming, close-range rapid acquisition, etc.).

[0003] In existing technologies, some scopes attempt to illuminate differentiated patterns using a single light source or employ a non-switchable composite pattern structure, but this has significant drawbacks: First, the pattern combination is fixed, making it impossible to select only the central aiming point or the outer auxiliary pattern according to actual needs, resulting in insufficient flexibility; second, the colors are unchangeable, and a single color is prone to low visibility under different lighting conditions (e.g., red light has poor visibility in strong light, and green light has insufficient penetration in low light); third, the differentiated patterns are not expandable, and changing the pattern style requires replacing the entire core component of the scope, which is complex and costly; fourth, when multiple patterns are illuminated, light source interference is prone to occur, resulting in blurred patterns and unclear boundaries, affecting aiming accuracy.

[0004] Furthermore, traditional multi-pattern sights lack effective light-blocking and isolation structures. When multiple light sources illuminate different patterns, the light rays are prone to crosstalk, causing ghosting of other patterns to appear even when only one pattern is illuminated, reducing aiming accuracy. Therefore, there is an urgent need for a sight pattern illumination solution that allows for free combination and multi-color switching of differentiated patterns, possesses anti-interference capabilities, and is flexibly expandable, in order to solve the problems of poor flexibility, weak environmental adaptability, and insufficient accuracy in existing technologies. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-pattern differentiation graphic illumination system and apparatus for a scope, so as to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a multi-patterned pattern illumination system for a sight, including an optical reflection component, a pattern carrier component, a multi-source light source component, and an optical transmission component;

[0007] The differentiation support component is disposed on the first surface of the optical reflection component, the multi-source component is configured correspondingly to the optical reflection component, and the optical transmission component is configured correspondingly to the light emission path of the optical reflection component;

[0008] The differentiation bearing component is provided with at least two concentrically arranged differentiation pattern units, the differentiation pattern unit includes a first pattern unit located at the center and a second pattern unit located on the outer ring, and the surface of the second pattern unit is provided with a light-shielding structure;

[0009] The multi-light source component includes at least two independently controlled light sources, each of which is adapted to a different differentiation pattern unit to achieve selective illumination of different differentiation pattern units;

[0010] Each of the light sources can switch to output different colors of light. Through independent switching control and color switching of the light sources, the combination selection of differentiated graphic units and the free adaptation of multi-color display can be realized.

[0011] In a further embodiment of the present invention, the first graphic unit and the second graphic unit are concentrically arranged, and the size of the first graphic unit is smaller than the size of the second graphic unit.

[0012] In a further embodiment of the present invention, the light-shielding structure is a light-shielding coating applied to the upper surface of the second graphic unit. The light-shielding coating is made of an opaque material and is used to block the ineffective illumination of the second graphic unit by non-corresponding light sources.

[0013] In a further embodiment of the present invention, the light-shielding coating is a black coating, and the light transmittance of the black coating is ≤0.01%.

[0014] In a further embodiment of the present invention, the multi-light source assembly includes a first LED lamp and a second LED lamp;

[0015] The first LED light is concentrically positioned directly above the first graphic unit to provide directional illumination to the first graphic unit.

[0016] The second LED is disposed on the outer side of the second surface of the optical reflective component, and is used to penetrate into the optical reflective component to directionally illuminate the second graphic unit.

[0017] In a further embodiment of the present invention, the first graphic unit is a dot, a cross, or other preset graphic, and the second graphic unit is a solid line, a dashed line, or other preset graphic.

[0018] The differentiation support component is a detachable and replaceable structure. By replacing the differentiation support component with a different differentiation pattern design, the differentiation pattern can be diversified and expanded.

[0019] In a further embodiment of the present invention, the color switching range of the light source includes at least two of red light, green light, blue light, and yellow light, and the color switching of each light source is independently controllable.

[0020] A multi-pattern differentiation pattern illumination device for a sight includes a multi-pattern differentiation pattern illumination system for a sight, wherein the optical reflection component is a prism, the optical transmission component is a lens, and the differentiation support component is a differentiation plate;

[0021] The first face of the prism is fixedly equipped with the differentiation plate, on which the first pattern unit and the second pattern unit are etched. The upper surface of the second pattern unit is coated with a light-shielding coating, which is a black opaque material with a light transmittance of ≤0.01%.

[0022] The second LED light is fixedly installed on the outer side of the second surface of the prism. The first LED light is concentrically fixed above the first graphic unit by a bracket, and the light-emitting center of the first LED light coincides with the geometric center of the first graphic unit.

[0023] The light-shielding coating is used to block the light emitted by the first LED from illuminating the second graphic unit, ensuring that the first LED only acts on the first graphic unit, and the light emitted by the second LED only acts on the second graphic unit after being transmitted through the inside of the prism.

[0024] In a further embodiment of the present invention, the light emitted by the first LED lamp is reflected by the first graphic unit and then reflected by the reflective surface of the prism to form parallel light, which is then clearly received by the human eye after passing through the lens.

[0025] After the light emitted by the second LED enters the prism, it is conducted through the inside of the prism to the second graphic unit and reflected. Then, it is reflected by the prism's reflective surface to form parallel light. The parallel light passes through the lens and is clearly received by the human eye.

[0026] The light-shielding coating ensures that when a single light source is working, it only images the corresponding differentiated graphic unit, and when multiple light sources are working simultaneously, it achieves the composite imaging of the complete differentiated graphic.

[0027] In a further embodiment of the present invention, the lens and the light-emitting surface of the prism are coaxially arranged, the focal length of the lens is adapted to the reflected light path length of the prism, and the effective aperture of the lens covers the maximum outer diameter of the second graphic unit to ensure complete imaging of the differentiated pattern.

[0028] The differentiation board is a detachable structure. By disassembling and replacing differentiation boards with different first graphic units and second graphic units, combined with independent switching control of the light source and color switching, the free expansion of differentiation graphic combination and multi-color display can be realized.

[0029] The beneficial effects of this invention are:

[0030] 1. Flexible and diverse graphic combinations to adapt to various aiming needs: This invention, by setting at least two concentrically arranged differentiated graphic units (a central first graphic unit and an outer second graphic unit), combined with independently controlled multi-light source components, can freely switch between illuminating a single graphic unit and illuminating multiple graphic units in combination. When only the first graphic unit is illuminated, it is suitable for long-range precision aiming; when only the second graphic unit is illuminated, it is suitable for close-range rapid target acquisition; when both are illuminated, a complete differentiated graphic is formed, adapting to auxiliary aiming in complex environments, greatly improving the scene adaptability of the scope.

[0031] 2. Multi-color switching function enhances recognition in all environments: Each light source supports independent color switching, allowing selection of appropriate colors (such as red, green, blue, yellow, etc.) based on different lighting environments (strong light, weak light, foggy weather, etc.). This solves the problem of low recognition of traditional fixed-color differentiation patterns in specific environments. For example, switching to red or green light in low light environments enhances penetration; switching to blue or yellow light in strong light environments avoids glare interference, ensuring clear recognition of differentiation patterns in all scenarios and improving aiming reliability.

[0032] 3. Light-shielding structure design to eliminate light source crosstalk and ensure aiming accuracy: By setting an opaque light-shielding coating (transmittance ≤0.01%) on the surface of the second graphic unit, invalid illumination from non-corresponding light sources can be effectively blocked, preventing the light from the first LED from interfering with the second graphic unit, or vice versa. This ensures that when a single light source is working, only the corresponding graphic unit is clearly imaged, without ghosting or crosstalk; when multiple light sources are working simultaneously, the boundaries of each graphic unit are clear and the superposition is accurate, significantly improving aiming accuracy.

[0033] 4. Expandable pattern, reduced cost of use: The differentiation support component (differentiation plate) adopts a detachable and replaceable structure. By replacing the differentiation plate with different graphic designs (such as the first graphic unit being a dot or a cross, and the second graphic unit being a solid line or a dashed line), the differentiation pattern can be diversified without replacing the core components of the scope. This adapts to different target types and aiming habits. Compared with the traditional whole replacement method, it is more convenient to operate and has a lower cost of use.

For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Additionally, features described with reference to certain examples may be combined in other examples.

[0041] This embodiment provides a multi-style differentiation pattern illumination system for a sight, including an optical reflection component 1, a differentiation support component A, a multi-source light source component, and an optical transmission component 7;

[0042] The differentiation support component A is detachably fixed to the first surface of the optical reflection component 1. The two are fitted together to ensure the stability of optical transmission. The multi-source component is adapted to different sides of the optical reflection component 1 to ensure that the light from each source can be accurately transmitted to the target differentiation graphic unit. The optical transmission component 7 is coaxially corresponding to the light emission path of the optical reflection component 1 and is used to optimize the reflected parallel light to improve the clarity received by the human eye.

[0043] The differentiation bearing component A is integrally formed with at least two concentrically arranged differentiation graphic units. The differentiation graphic unit includes a first graphic 2 located in the central region and a second graphic 3 surrounding the outside of the first graphic 2. The upper surface of the second graphic 3 is completely covered with a light-shielding structure 4, which can achieve precise isolation of light from the light source and avoid crosstalk between different light sources.

[0044] The multi-light source component includes at least two independently controlled light sources. Each light source is independently controlled in its switching state through a circuit module. The illumination direction of each light source is precisely matched with different differentiated graphic units, thereby realizing individual or combined lighting control of different differentiated graphic units.

[0045] Each of the light sources has a built-in color switching module, which can switch the output of monochromatic light of different wavelengths according to the usage requirements. Through independent switching control and color switching operation of each light source, multiple combinations of the differentiation graphic units and free adaptation of multi-color display modes can be realized, which greatly improves the system's adaptability to different usage scenarios and solves the technical defects of fixed differentiation graphics and single color in traditional sights.

[0046] In this embodiment, the first graphic 2 and the second graphic 3 are designed to be concentric and coaxial, with their geometric centers completely overlapping. The overall size of the first graphic 2 is smaller than that of the second graphic 3, wherein the maximum outer diameter of the first graphic 2 does not exceed 1 / 3 of the minimum inner diameter of the second graphic 3. This size design ensures that the first graphic 2 does not obstruct the auxiliary aiming function of the second graphic 3 when used as the core aiming reference, while also ensuring visual coordination when the two are displayed together, thus improving the convenience and accuracy of aiming operations.

[0047] In this embodiment, the light-shielding structure 4 is a light-shielding coating uniformly coated on the upper surface of the second graphic 3. The coating thickness is controlled between 0.05-0.1mm, which ensures the light-shielding effect without affecting the overall flatness of the differentiation support component A. The light-shielding coating is a high-density opaque material, and its material composition includes a mixture of carbon black powder and high-temperature resistant resin. The main function of the light-shielding coating is to block the ineffective illumination of the second graphic 3 by non-corresponding light sources (i.e., the light source used to illuminate the first graphic 2), and to prevent the second graphic 3 from showing ghost images or reflections when the first graphic 2 is lit, thereby ensuring the display purity when a single graphic unit is lit, and thus improving aiming accuracy.

[0048] In this embodiment, the light-shielding structure 4 is a black coating. By optimizing the coating formula and coating process, the light transmittance of the black coating is ≤0.01%. Such low light transmittance can achieve a near-complete light-shielding effect. Even under strong light irradiation, it can completely block the penetration of light from non-corresponding light sources, ensuring that when the first graphic 2 is lit alone, the second graphic 3 does not emit light at all. When the second graphic 3 is lit alone, the light is only transmitted through its own reflection path and will not interfere with the display of the first graphic 2. This extreme light-shielding effect brings unexpected advantages, namely, the display boundaries of different differentiated graphic units are clear and distinct, without any overlapping or blurry areas, which significantly improves the accuracy of aiming.

[0049] In this embodiment, the multi-light source assembly includes a first LED 6 and a second LED 5. Both the first LED 6 and the second LED 5 are high-brightness, low-power surface-mount LEDs, and have a built-in constant current drive module to ensure light emission stability. The first LED 6 is fixedly mounted above the first graphic 2 via an adjustable bracket, with its light emission center coaxially aligned with the geometric center of the first graphic 2. The light emission angle is controlled between 15-30° to achieve directional and concentrated illumination of the first graphic 2, avoiding energy waste and interference caused by light diffusion. The second LED 5 is mounted on the outer side of the second surface of the optical reflection component 1 via a mounting base. Its mounting position corresponds to the position of the second graphic 3, and its light emission direction is perpendicular to the second surface of the optical reflection component 1. The second surface is on the side of the optical reflection component 1, and the first surface is on the top of the optical reflection component 1. It is used to penetrate into the interior of the optical reflection component 1 and then directionally illuminate the second graphic 3 through the internal conduction of the optical reflection component 1. This layout design can fully utilize the light transmission characteristics of the optical reflection component 1 to ensure that the light from the second LED 5 acts efficiently on the second graphic 3, thereby improving light utilization.

[0050] In this embodiment, the first graphic 2 can be designed as a dot, a cross, a triangle, or other preset aiming graphic, and the second graphic 3 can be designed as a solid ring line, a segmented dashed line, a scale line, or other preset auxiliary graphic. Different graphic designs are adapted to different usage scenarios such as long-distance precise aiming, close-range rapid acquisition, and dynamic target tracking. The differentiation support component A is a snap-on detachable and replaceable structure. Its edge is provided with a positioning slot and optical reflection component 1 to achieve precise positioning and assembly. By disassembling and replacing the differentiation support component A with different designs of the first graphic 2 and the second graphic 3, the core optical components of the scope do not need to be replaced, and the differentiation pattern can be diversified and expanded, reducing the user's usage cost and greatly expanding the scope of application of the scope. Compared with the traditional scope solution that requires the replacement of the entire core component, it has significant advantages in convenience and economy.

[0051] In this embodiment, the color switching range of the light source includes at least two of the following: red light (wavelength 620-660nm), green light (wavelength 520-550nm), blue light (wavelength 450-475nm), and yellow light (wavelength 580-595nm). The color switching of each light source is independently controllable through an independent control button or wireless remote control module. Red light is suitable for long-distance aiming in low-light environments and has strong penetration; green light is suitable for medium-light environments and has high visual recognition; blue light is suitable for strong light environments and can effectively avoid reflection interference; yellow light is suitable for complex weather conditions such as fog and sandstorms and can improve the clarity of graphic outlines. This multi-color independent switching design enables the system to adapt to various harsh environments such as strong light, low light, and complex weather, achieving clear aiming in all scenarios and bringing unexpected environmental adaptability.

[0052] Another embodiment provides a multi-pattern illumination device for a sight, including the aforementioned multi-pattern illumination system for a sight. The optical reflection component 1 is a prism made of high-transmittance optical glass with a refractive index ≥1.52 to minimize light loss during transmission. The optical transmission component 7 is an achromatic cemented doublet lens, which effectively eliminates chromatic aberration and spherical aberration, improving image quality. The differentiation support component A is a high-precision etched differentiation plate. The first surface of the prism is fixedly mounted on the differentiation support component A by optical adhesive. The surface of component A is polished to a roughness Ra≤0.01μm. The first pattern 2 and the second pattern 3 are formed on it using laser etching, with the etching depth controlled between 0.02-0.03mm to ensure clear pattern outlines without affecting light reflection. The upper surface of the second pattern 3 is uniformly coated with a light-shielding structure 4 using a spraying process. The light-shielding structure 4 is a black, opaque material, primarily a composite of carbon black and epoxy resin, and undergoes high-temperature curing to ensure strong coating adhesion and resistance to peeling. The light transmittance of this black coating is ≤0.01%, enabling... The optical reflector 1 achieves complete light blocking. The second LED 5 is fixedly mounted on the outer side of its second surface via a metal bracket. A buffer pad is provided between the bracket and the optical reflector 1 to prevent vibration from affecting the optical components. The first LED 6 is concentrically fixed above the first graphic 2 via an adjustable-height bracket, with the light-emitting center of the first LED 6 completely coinciding with the geometric center of the first graphic 2, with a deviation of no more than 0.01mm. The light-blocking structure 4 precisely blocks the light emitted by the first LED 6 from illuminating the second graphic 3, ensuring that the light from the first LED 6 only affects the first graphic 2, achieving a clear display of the first graphic 2. The light emitted by the second LED 5, after penetrating the optical reflector 1, is transmitted to the second graphic 3 via a total internal reflection path and is reflected. Due to the isolation effect of the light-blocking structure 4, this light will not interfere with the first graphic 2, but only affects the second graphic 3. This precise light isolation design solves the light source crosstalk problem present in traditional multi-graphic sights, bringing unexpected technical effects of high graphic display purity and high aiming accuracy.

[0053] In this embodiment, the light emitted by the first LED 6 is reflected by the surface of the first pattern 2 and then incident perpendicularly on the reflective surface of the optical reflective component 1. Through total internal reflection, parallel light is formed, with a divergence angle ≤0.5°. This parallel light passes through the optical transmission component 7 along its light exit path and is then focused and optimized by the optical transmission component 7 to form a clear real image for the human eye to receive, ensuring that the first pattern 2 observed by the human eye is free of distortion and ghosting. The light emitted by the second LED 5 is perpendicularly transmitted into the second surface of the optical reflective component 1 and then directionally transmitted through the optical transmission path inside the optical reflective component 1 to the lower surface of the second pattern 3. The reflection of the second graphic 3 changes the propagation direction, and then the total internal reflection of the reflective surface of the optical reflection component 1 forms parallel light. After passing through the optical transmission component 7, the parallel light is coaxially superimposed with the parallel light reflected by the first graphic 2, allowing the human eye to receive it clearly. The light-shielding structure 4, through its extreme light-shielding performance, blocks the invalid illumination of non-corresponding light sources, ensuring that when a single light source is working, it only corresponds to the differentiated graphic unit with clear imaging, without any ghosting or interfering light spots. When multiple light sources work simultaneously, the imaging of each differentiated graphic unit is independent and the boundaries are clear, realizing the accurate synthesis imaging of the complete differentiated graphic. This design not only improves the accuracy of aiming, but also reduces the observation fatigue of the human eye, bringing a better user experience.

[0054] In this embodiment, the optical transmission component 7 and the optical reflection component 1 are coaxially arranged with a coaxiality deviation of ≤0.02mm. The focal length of the optical transmission component 7 is precisely matched with the reflected light path length of the optical reflection component 1, with the matching error controlled within ±0.5mm, ensuring that the reflected parallel light can form a clear image through the optical transmission component 7. The effective aperture of the optical transmission component 7 is larger than the maximum outer diameter of the second pattern 3, and the coverage area exceeds the maximum outer diameter of the second pattern 3 by at least 2mm, to ensure that the edge part of the differentiated pattern can be completely imaged without any cutting or missing parts; the differentiated bearing component A features a snap-on, detachable structure with positioning pins on its edges that engage with positioning holes on the optical reflection assembly 1, enabling quick disassembly and precise assembly. By disassembling and replacing the differentiated support assembly A with different first graphic 2 and second graphic 3 designs, combined with independent switch control and color switching functions for each light source, the combination of differentiated graphics and multi-color display modes can be infinitely expanded, adapting to various usage scenarios such as long-range shooting, close-range tactical combat, hunting, and outdoor observation. Compared to the fixed design of traditional scopes, its flexibility and applicability have been qualitatively improved, achieving the unexpected effect of "one scope adapting to all scenario needs".

[0055] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
