Description

Technical Field

[0001] This utility model relates to the field of sights, and more particularly to a light-emitting device and a sight. Background Technology

[0002] A reflex sight is a non-magnified optical aiming device, typically mounted on firearms, used to assist in aiming at targets. A reflex sight contains a light-emitting mechanism and a reflector. The light emitted by the light-emitting mechanism is reflected by the reflector to form an aiming point, which the operator can align with the target point to perform firing operations.

[0003] The light-emitting mechanism includes an LED module and an aperture. The aperture only allows paraxial light emitted from the LED module to enter the imaging channel. In existing technology, an LED module generally includes two LEDs of different colors, which are typically arranged horizontally, vertically, or at other angles. Taking a horizontal arrangement of two different colored LEDs as an example, due to the limited distance between them, only the portion of the light emitted by each LED close to the aperture passes through it. Because there is a distance between the two LEDs and the aperture's through-hole, the aiming point formed by the light emitted from the LED on the left after passing through the aperture will be offset to the left, while the aiming point formed by the light emitted from the LED on the right after passing through the aperture will be offset to the right. When switching between two colors of LED lights, the two different colors of light will shine on the reflector after passing through the aperture. As a result, the aiming points of the two colors will not be in a fixed position, causing the two aiming points to deviate. Consequently, the two target points cannot be focused on the same target at the same time, resulting in the loss of the final target during shooting.

[0004] Therefore, those skilled in the art are dedicated to developing a light-emitting device and a sight that can improve aiming accuracy. Utility Model Content

[0058] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0059] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the illustrations only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0060] Some exemplary embodiments of the present invention have been described for illustrative purposes. It should be understood that the present invention may be implemented in other ways not specifically shown in the accompanying drawings.

[0061] like Figures 1 to 8 As shown, in a preferred embodiment of this utility model, a light-emitting device 1 is mounted on a sight to assist the operator in aiming at a target. The sight includes the light-emitting device 1 and a reflector 2. The specific path of the light emitted by the light-emitting device 1 is as follows: the light emitted by the light-emitting device 1 is reflected by the reflector 2 and projected into an aiming point in the operator's line of sight, thereby enabling the operator to acquire the target more quickly and improve the accuracy of shooting.

[0062] Specifically, the light-emitting device 1 includes a light-emitting mechanism 11 and a light-guiding mechanism 12. The light-emitting mechanism 11 is used to emit light, and the light-guiding mechanism 12 is disposed on the light-emitting side of the light-emitting mechanism 11 and has a light-guiding section. The light-guiding section is configured to allow the running light beam of the light-emitting mechanism 11 to follow a preset path.

[0063] The operating beam of the aforementioned light-emitting mechanism 11 is the beam emitted when the light-emitting mechanism 11 is powered on and illuminated. The aforementioned preset route is the route by which the operating beam, after passing through the light guide, is projected onto the reflector 2 and reflected by the reflector 2 into the operator's line of sight.

[0064] In one embodiment, the light guiding mechanism 12 includes an aperture 121 with a light-passing hole 122, which serves as a light guide. The aperture 121 is an important component in the optical system, primarily used to control the light beam. In this embodiment, since the light-passing hole 122 serves as a light guide, the light beam emitted by the light-emitting mechanism 11 is limited by the light-passing hole 122, thus limiting the light flux (light intensity).

[0065] The aperture of the aperture 122 in the aperture 121 can be changed to directly adjust the amount of light passing through. A larger aperture 122 results in a larger amount of light passing through, while a smaller aperture results in a smaller amount of light passing through. In this embodiment, the aperture 121 is not specifically limited and is determined based on actual conditions.

[0066] Furthermore, the aperture 121 can also block stray light, scattered light or emitted light that deviates from the preset path and / or is unwanted from entering the imaging surface, thereby significantly improving the contrast and sharpness of the image, reducing glare and ghosting, and improving the image quality.

[0067] Specifically in this embodiment, the aperture 121 can block part of the light emitted by the light-emitting mechanism 11, so that the running light beam near the light-transmitting hole 122 of the aperture 121 can be projected onto the reflector 2 through the light-transmitting hole 122, while the running light beam away from the light-transmitting hole 122 is blocked by the aperture 121.

[0068] In another embodiment, the light guiding mechanism 12 includes a light guide column having a light-blocking element and a light guide column that passes through the light-blocking element, the light guide column serving as a light guiding part. Accordingly, part of the running light beam is blocked by the light-blocking element, while the remaining running light beam that is not blocked is transmitted through the light guide column and projected onto the reflector, and then reflected by the reflector into the operator's line of sight.

[0069] The size of the light-blocking component is greater than or equal to the illumination range of the running beam. Furthermore, the light guide post is positioned at the center of the light-blocking component to facilitate the arrangement of the light-emitting mechanism 11 and to concentrate the running beam of the light-emitting mechanism 11, thereby ensuring that the light energy of the running beam guided by the light guide post is sufficiently large to meet the visual needs of different scenarios.

[0070] The light guide can be made of optical-grade polymethyl methacrylate, which has a light transmittance close to that of glass, resulting in minimal light loss and high efficiency during internal propagation of the light beam; alternatively, the light guide can be made of optical-grade cyclic olefin polymer, which has both extremely high light transmittance and extremely low birefringence, resulting in minimal distortion of light and clearer imaging. No specific limitations are made here, and the choice depends on the actual situation.

[0071] In the following description, the light guide mechanism 12 is specifically illustrated using the aperture 121 as an example.

[0072] Conventional sights typically use a single-color light source (11) for their light emission mechanism, limiting their application scenarios. If the operator needs to use the sight in different environments, a separate light source (1) of a different color is required. Therefore, sights with two-color aiming points have been developed to adapt to various scenarios. These two colors are usually green and red. The red aiming point uses a red-emitting point light source, while the green aiming point uses a green-emitting point light source. The red aiming point is suitable for backgrounds with a color significantly different from red light, such as cool-toned environments like forests or oases; the green aiming point is suitable for backgrounds with a color significantly different from green light, such as warm-toned environments like deserts or Gobi. Red and green aiming points can essentially cover all usage scenarios.

[0073] Both the red-emitting and green-emitting point light sources mentioned above are LED lights.

[0074] In existing technology, two LEDs of different colors are generally arranged horizontally, vertically, or at other angles. Taking two LEDs of different colors arranged horizontally as an example, due to the limited distance between the two LEDs, only the portion of the light emitted by each LED near the aperture 121 passes through the aperture 121. Since there is a distance between the two LEDs and the through-hole of the aperture 121, the aiming point formed by the light emitted from the LED on the left after passing through the aperture 121 will be biased to the left, while the aiming point formed by the light emitted from the LED on the right after passing through the aperture 121 will be biased to the right. When switching between the two colors of LEDs, the aiming points of the two colors will not be in a fixed position when they shine onto the reflector 2 after passing through the aperture 121. This deviation in aiming points prevents the two target points from being simultaneously focused on the same target, resulting in the loss of the final target during shooting.

[0075] The phenomenon described above, where the aiming points of the two colors are not in a fixed position, is also known as POI (point of aim). A larger POI value indicates a greater distance between the aiming points of the two colors, which exacerbates the deviation from the target. Conversely, a smaller POI value indicates a smaller distance between the aiming points of the two colors, making it easier for the operator to aim at the target.

[0076] To address the aforementioned technical problems, the light-emitting mechanism 11 in this embodiment includes a substrate 111 and a first light module and a second light module disposed on the substrate 111. Of course, in other embodiments, the light-emitting mechanism 11 may also include a first light module, a second light module, a third light module, a fourth light module, etc., and is not specifically limited here, depending on the actual situation. In this embodiment, the first light module and the second light module correspond to the two different color light modules mentioned above. When the number of colors increases, the number of light modules also increases accordingly for each additional different color. Therefore, this embodiment does not specifically limit the number of light modules; the first light module and the second light module are used for illustrative purposes in this specific embodiment.

[0077] The first light module is symmetrically arranged along the light guide and has a first arrangement path, while the second light module is symmetrically arranged along the light guide and has a second arrangement path. The first and second arrangement paths intersect. By making the first and second arrangement paths intersect, the first and second light modules are staggered, allowing the operating beams of the first and second light modules to be projected onto the guiding mechanism at different angles. This results in a larger range of operating beams concentrated at the light guide of the guiding mechanism, leading to greater light energy and greater brightness at the aiming point reflected in the operator's line of sight. Furthermore, the operating beams of both the first and second light modules can be concentrated at the light guide to form a larger operating beam range, reducing the occurrence of the operating beam deviating from one side of the light guide. This also facilitates the overlap of the aiming points reflected from the operating beams of the two different colored first and second light modules in the operator's line of sight, thereby improving aiming accuracy.

[0078] In this embodiment, the operating beam of the first light module is red, and the operating beam of the second light module is green. Correspondingly, the aiming points formed by the first and second light modules are red and green, respectively, to meet the needs of different environmental scenarios. Of course, in other embodiments, the operating beam of the first light module may also be green, and the operating beam of the second light module may also be red; no specific limitation is made here, and it depends on the actual situation.

[0079] The first lighting module and the second lighting module are arranged alternately so that the first arrangement path of the first lighting module intersects with the second arrangement path of the second lighting module.

[0080] The first lighting module includes two first light-emitting devices, and the second lighting module includes two second light-emitting devices. A first connection is provided between each of the first light-emitting devices and the other first light-emitting device, and a second connection is provided between each of the second light-emitting devices and the other second light-emitting device. The first and second connections intersect.

[0081] At this time, the intersection of the first and second lines indicates that the two first light-emitting devices are arranged diagonally, and the two second light-emitting devices are arranged diagonally. This allows the running beams of the two first light-emitting devices and the two second light-emitting devices to converge at the light guide 122. Therefore, the running beams of the two diagonally arranged light-emitting elements can coincide or substantially coincide with the aiming point in the operator's line of sight after passing through the light guide 122 and the reflector 2. At this time, the POI value is equal to 0 or approximately equal to 0, which makes it easier for the operator to aim at the target.

[0082] Of course, the first lighting module mentioned above may also include three or more first light-emitting devices, and the second lighting module may also include three or more second light-emitting devices. In this case, any one of the first light-emitting devices and another first light-emitting device arranged adjacent to it have a first connecting line, and the second light-emitting device arranged on one side of the first light-emitting device and another second light-emitting device arranged adjacent to the first light-emitting device have a second connecting line. The first connecting line and the second connecting line intersect. At this time, the intersection of the first connecting line and the second connecting line indicates that the three or more first light-emitting devices are staggered and the three or more second light-emitting devices are staggered. Alternatively, the intersection of the first connecting line and the second connecting line indicates that the three or more first light-emitting devices and the three or more second light-emitting devices are staggered. The above-mentioned technical effect can be achieved in the same way.

[0083] Specifically, the first arrangement route of the first lighting module and the second arrangement route of the second lighting module intersect to form an intersection point 31. The intersection point 31 coincides with the center point of the light guide section 122, or the intersection point 31 is symmetrically arranged along the light guide section 122, or any intersection point is symmetrically arranged along the light guide section with the line connecting two adjacent intersection points.

[0084] In one embodiment, the first lighting module includes two first light-emitting devices, and the two first light-emitting devices are arranged diagonally along the light guide portion. The second lighting module includes two second light-emitting devices, and the two second light-emitting devices are arranged diagonally along the light guide portion. At this time, the first and second arrangement paths intersect to form an intersection point, and the intersection point coincides with the center point of the light guide portion 122.

[0085] The beams of light from the two first light-emitting devices arranged diagonally can converge at the light guide 122, and the beams of light from the two second light-emitting devices arranged diagonally can also converge at the light guide 122. Therefore, the beams of light from the two first light-emitting devices arranged diagonally are reflected by the light guide 122 and the reflector 2 to the aiming point in the operator's line of sight. The beams of light from the two second light-emitting devices arranged diagonally are reflected by the light guide 122 and the reflector 2 to the aiming point in the operator's line of sight, and can coincide or substantially coincide. At this time, the value of POI is equal to 0 or approximately equal to 0, which makes it easier for the operator to aim at the target.

[0086] The angle between the line connecting the two diagonally arranged first light-emitting devices to the light guide 122 and the horizontal line is 45°. This allows the beams of light from the two diagonally arranged first light-emitting devices to be better concentrated in the light guide 122. Similarly, the angle between the line connecting the two diagonally arranged second light-emitting devices to the light guide 122 and the horizontal line is 45°. This also allows the beams of light from the two diagonally arranged second light-emitting devices to be better concentrated in the light guide 122. Through this method, while ensuring that aiming points of different colors can coincide, the brightness of the aiming points is also maintained, further improving aiming accuracy.

[0087] In other embodiments, the angle between the line connecting the two diagonally arranged first light-emitting devices and the light guide portion 122 and the horizontal line can also be other values, such as 15°, 30°, 60°, 75°, etc. Similarly, the angle between the line connecting the two diagonally arranged first light-emitting devices and the light guide portion 122 and the horizontal line can also be other values, such as 15°, 30°, 60°, 75°, etc., without being specifically limited here, and can be determined according to the actual situation.

[0088] Furthermore, the spacing between the two first light-emitting devices is greater than 0 nm and less than or equal to 200 nm, which can further ensure the brightness of the formed aiming point. Preferably, the spacing between the two first light-emitting devices is greater than or equal to 50 nm and less than or equal to 150 nm to further meet the requirements.

[0089] Similarly, the spacing between the two second light-emitting devices is greater than 0 nm and less than or equal to 200 nm, which can further ensure the brightness of the formed aiming point. Preferably, the spacing between the two second light-emitting devices is greater than or equal to 50 nm and less than or equal to 150 nm, to further meet the requirements.

[0090] It is worth noting that the above values ​​include all lower and upper values ​​that increase by one unit from the lower limit to the upper limit, with at least a two-unit interval between any lower value and any higher value.

[0091] For example, the spacing range between the two first light-emitting devices and the spacing range between the two second light-emitting devices are both 0nm-200nm, preferably 50nm-150nm, in order to illustrate values ​​such as 60nm, 70nm, 80nm, 90nm, 100nm, 110nm, 120nm, 130nm, 140nm, etc., which are not explicitly listed above.

[0092] As mentioned above, the example range with intervals of 10 does not preclude growth with intervals of appropriate units such as 5, 15, 20, etc. These are merely examples intended to clarify the point, and it can be assumed that all possible combinations of values ​​listed between the minimum and maximum values ​​are explicitly described in this specification in a similar manner.

[0093] Unless otherwise stated, all ranges include the endpoints and all numbers between them. The terms "approximately" or "about" used with ranges apply to both endpoints of the range. Thus, "approximately 20 to 30" is intended to cover "approximately 20 to approximately 30," including at least the specified endpoints.

[0094] Other limitations on numerical ranges mentioned in this article can be found in the above description and will not be repeated here.

[0095] Alternatively, the first light module includes two first light-emitting devices, and the second light module includes two second light-emitting devices. In this case, the first arrangement of the two first light-emitting devices, which is diagonally arranged along the light guide, can also be described as the first arrangement of the two first light-emitting devices being symmetrically arranged along the light guide, and the two first light-emitting devices not being located on the same side. Similarly, the second arrangement of the two second light-emitting devices, which is diagonally arranged along the light guide, can also be described as the second arrangement of the two second light-emitting devices being symmetrically arranged along the light guide, and the two second light-emitting devices not being located on the same side.

[0096] The connection between the two first light-emitting devices passes through the center point of the light guide section 122, which also allows the beams from the two first light-emitting devices to be better concentrated in the light guide section 122. This ensures that the aiming points of different colors can coincide while also maintaining the brightness of the aiming points, further improving aiming accuracy. Similarly, the connection between the two second light-emitting devices passes through the center point of the light guide section 122, which also allows the beams from the two second light-emitting devices to be better concentrated in the light guide section 122. This ensures that the aiming points of different colors can coincide while also maintaining the brightness of the aiming points, further improving aiming accuracy.

[0097] Correspondingly, the angle between the line connecting the two first light-emitting devices symmetrically arranged along the light guide section and not located on the same side and the light guide section 122 and the horizontal line is 45°. At this time, the running beams of the two first light-emitting devices arranged diagonally can be better concentrated in the light guide section 122, ensuring that the aiming points of different colors can coincide while also ensuring the brightness of the aiming points, thereby further improving the aiming accuracy.

[0098] The angle between the line connecting the two second light-emitting devices symmetrically arranged along the light guide section and not located on the same side and the horizontal line of the light guide section 122 is 45°. At this time, the running beams of the two second light-emitting devices arranged diagonally can be better concentrated in the light guide section 122. While ensuring that the aiming points of different colors can coincide, the brightness of the aiming points can also be guaranteed, further improving the aiming accuracy.

[0099] In other embodiments, the angle between the line connecting the two first light-emitting devices symmetrically arranged along the light guide portion and not located on the same side and the light guide portion 122 and the horizontal line can also be other values, such as 15°, 30°, 60°, 75°, etc., which are not specifically limited here and are determined according to the actual situation.

[0100] In other embodiments, the angle between the line connecting the two second light-emitting devices symmetrically arranged along the light guide portion and not located on the same side and the light guide portion 122 and the horizontal line can also be other values, such as 15°, 30°, 60°, 75°, etc., which are not specifically limited here and are determined according to the actual situation.

[0101] In another embodiment, the first lighting module includes three or more first light-emitting devices, which are staggered. The second lighting module includes three or more second light-emitting devices, which are staggered. In this case, the intersection points formed by the first arrangement path of the first lighting module and the second arrangement path of the second lighting module are symmetrically arranged along the light guide portion 122, or the line connecting any one intersection point with two adjacent intersection points is symmetrically arranged along the light guide portion.

[0102] Specifically, when the first light module includes three first light-emitting devices, the three first light-emitting devices are arranged in a triangular shape. As mentioned above, the first arrangement route and the second arrangement route intersect. Correspondingly, when the second light module includes three second light-emitting devices, the three second light-emitting devices are also arranged in a triangular shape. The operating beams of each first light module and the second light module can converge at the light guide 122. The operating beams of the three triangularly arranged first light-emitting devices, after passing through the light guide 122 and being reflected by the reflector 2, can overlap or substantially overlap at the aiming point in the operator's line of sight. At this time, the POI value is equal to 0 or approximately equal to 0, which facilitates the operator's aiming at the target. The operating beams of the three triangularly arranged second light-emitting devices, after passing through the light guide 122 and being reflected by the reflector 2, can overlap or substantially overlap at the aiming point in the operator's line of sight. At this time, the POI value is equal to 0 or approximately equal to 0, which facilitates the operator's aiming at the target.

[0103] At this time, the triangle of the first arrangement path of the three first light-emitting devices of the first light module is an equilateral triangle, and the triangle of the second arrangement path of the three second light-emitting devices of the second light module is an inverted triangle. The first arrangement path of the equilateral triangle and the second arrangement path of the inverted triangle form two intersection points on both sides of the light guide, and the two intersection points are symmetrical with respect to the light guide, so as to achieve the effect that the two color aiming points formed in the end can coincide or basically coincide.

[0104] When the first light module includes four first light-emitting devices and the second light module includes four second light-emitting devices, the first arrangement path of the four first light-emitting devices is in a square or rectangular distribution, and the second arrangement path of the four second light-emitting devices is in a square or rectangular distribution. Accordingly, the square or rectangular first arrangement path and the square or rectangular second arrangement path respectively form four intersection points on both sides of the light guide section. The four intersection points are symmetrical about each other relative to the light guide section, so as to achieve the effect that the two color aiming points formed in the end can coincide or basically coincide.

[0105] Similarly, when the first light module includes five, six, or seven first light-emitting devices, the first arrangement path of the five first light-emitting devices is pentagonal, the first arrangement path of the six first light-emitting devices is hexagonal, and the first arrangement path of the seven first light-emitting devices is heptagonal, etc. The second light module is set up in the same way. At this time, the first and second arrangement paths form multiple intersection points on both sides of the light guide, and the multiple intersection points are symmetrical with respect to the light guide, so as to achieve the effect that the two color aiming points formed in the end can coincide or basically coincide. This will not be elaborated in detail here.

[0106] As can be seen from the above, when the first light module includes three or more first light-emitting devices, and the three or more first light-emitting devices are staggered; and the second light module includes three or more second light-emitting devices, and the three or more second light-emitting devices are staggered, then the line connecting any intersection point to the two adjacent intersection points is symmetrically arranged along the light guide.

[0107] In this embodiment, a first line connects any one of the first light-emitting devices and another first light-emitting device disposed adjacent to it, and a second line connects a second light-emitting device disposed on one side of the first light-emitting device and another second light-emitting device disposed adjacent to it. The first line and the second line intersect. In this embodiment, the first line and the second line intersect with a first included angle α, where the first included angle α is greater than 0° and less than 180°.

[0108] Preferably, the first included angle α is greater than or equal to 30° and less than or equal to 90°. Similarly, it is worth noting that the above values ​​include all lower and upper values ​​that increase by one unit from the lower limit to the upper limit, with at least a two-unit interval between any lower value and any higher value.

[0109] For example, the range of the first included angle α is 0°-180°, preferably 30°-90°, in order to illustrate values ​​such as 40°, 50°, 60°, 70°, 80°, etc., which are not explicitly listed above.

[0110] As mentioned above, the example range with intervals of 10 does not preclude growth with intervals of appropriate units such as 5, 15, 20, etc. These are merely examples intended to clarify the point, and it can be assumed that all possible combinations of values ​​listed between the minimum and maximum values ​​are explicitly described in this specification in a similar manner.

[0111] Unless otherwise stated, all ranges include the endpoints and all numbers between them. The terms "approximately" or "about" used with ranges apply to both endpoints of the range. Thus, "approximately 20 to 30" is intended to cover "approximately 20 to approximately 30," including at least the specified endpoints.

[0112] Any first light-emitting device and the line connecting it to two adjacent first light-emitting devices are symmetrically arranged along the light guide section to further improve aiming accuracy. At this time, the first arrangement route of the first light module includes multiple first route segments, and there is a second included angle b between two adjacent first route segments, the second included angle b being greater than 0° and less than 180°.

[0113] Any second light-emitting device is symmetrically arranged along the light guide section with the line connecting it to two adjacent second light-emitting devices, further improving aiming accuracy. At this time, the second arrangement path of the second light module includes multiple second path segments, and there is a third included angle c between two adjacent second path segments, where the third included angle c is greater than 0° and less than 180°.

[0114] Taking a first lighting module with three first light-emitting devices as an example, one first light-emitting device and the line connecting it to the two adjacent first light-emitting devices form a first arrangement route, and the line connecting the first light-emitting device to the two adjacent first light-emitting devices is symmetrically arranged along the light guide. The first arrangement route includes two first route segments, and the second included angle b between two adjacent first route segments is 60°.

[0115] As the number of first light-emitting devices in the first light module increases, the number of first route segments in the first arrangement route also increases, and the second included angle b between two adjacent first route segments also increases, thus achieving the effect of improving aiming accuracy.

[0116] Similarly, taking a second light-emitting module with three second light-emitting devices as an example, one second light-emitting device and the line connecting it to the two adjacent second light-emitting devices form a second arrangement route, and the line connecting the second light-emitting device to the two adjacent second light-emitting devices is symmetrically arranged along the light guide. This second arrangement route includes two second route segments, and the included angle c between two adjacent second route segments is 60°.

[0117] As the number of second light-emitting devices in the second light module increases, the number of second route segments in the second arrangement route also increases, and the third included angle c between two adjacent second route segments also increases, thus achieving the effect of improving aiming accuracy.

[0118] This utility model also provides a light-emitting device 1, which also includes a light-emitting mechanism 11 and a light-guiding mechanism 12, and the light-emitting mechanism 11 and the light-guiding mechanism 12 have the same structure. That is, the light-emitting mechanism 11 also includes a first light module and a second light module. The light-guiding mechanism 12 is disposed on the light-emitting side of the light-emitting mechanism 11; the light-guiding mechanism 12 has a light-guiding part 122, which is configured to allow the running light beams of the first light module and the second light module to follow a preset path. The light-emitting mechanism 11 and the light-guiding mechanism 12 will not be described in detail here; please refer to the above for details.

[0119] Unlike the embodiments described above, in this embodiment, the first light module is symmetrically arranged along the light guide and the running beam of the first light module forms a first intersecting beam at the light guide. The second light module is symmetrically arranged along the light guide and the running beam of the second light module forms a second intersecting beam at the light guide. The first intersecting beam and the second intersecting beam overlap, or the first intersecting beam covers the second intersecting beam.

[0120] That is, in this embodiment, the overlap of the first intersection beam and the second intersection beam means that the range of the first intersection beam formed by the first light module at the light guide 122 and the range of the second intersection beam formed by the second light module at the light guide 122 are the same. Therefore, the range and brightness of the beam projected onto the reflector through the light guide 122 are equal, and the aiming points of the two colors formed in the end also overlap. At this time, the POI value is 0.

[0121] Alternatively, in this embodiment, the first intersection beam of the first light module covering the second intersection beam of the second light module means that the first intersection beam formed by the first light module at the light guide 122 always covers the second intersection beam formed by the second light module at the light guide 122. Therefore, the range of the beam projected by the first light module onto the reflector through the light guide 122 also always covers the range of the beam projected by the second light module onto the reflector through the light guide 122. Finally, the aiming points of the two colors formed are always one group covering the other group, and the POI value is also 0.

[0122] Furthermore, at least 30% of the operating beam range in the first lighting module intersects at the light guide 122, forming a first intersecting beam. At least 30% of the operating beam range in the second lighting module intersects at the light guide 122, forming a second intersecting beam.

[0123] Furthermore, the preset path coincides with the central axis of the light guide 122. At this time, the first intersection beam of the first light module is guided by the light guide 122 and projected onto the target component along the central axis. The second intersection beam of the second light module is guided by the light guide 122 and projected onto the target component along the central axis. This concentrates the brightness and also allows the aiming point to be located at the center of the line of sight, making it easier to observe whether the aiming points formed by the two light modules coincide and facilitating aiming at the target component.

[0124] This utility model also provides a sight, including a housing and a light-emitting device 1. A reflector 2 is mounted on the housing, and the light-emitting device 1 is adapted to emit a running beam. The running beam can be reflected by the reflector 2 to form an aiming point. The light-emitting device 1 is the sight as described above, and will not be described in detail here.

[0125] In summary: the light-emitting device 1 includes a light-emitting mechanism 11 and a light-guiding mechanism 12. The light-guiding mechanism 12 is disposed on the light-emitting side of the light-emitting mechanism 11 and has a light-guiding section 122. The light-emitting mechanism 11 includes a first light module and a second light module. The light-guiding section 122 ensures that the running beams of the first light module and the running beams of the second light module follow a preset path, thereby forming a final aiming point. The first light module is symmetrically arranged along the light-guiding section 122 and has a first arrangement path. The second light module is symmetrically arranged along the light-guiding section 122 and has a second arrangement path. The first and second arrangement paths intersect, thereby ensuring that the first light module and the second light module... The staggered arrangement allows the beams of the first light module to form a first intersecting beam at the light guide 122, and the beams of the second light module to form a second intersecting beam at the light guide 122. The transmission directions of both the first and second intersecting beams coincide with the central axis of the light guide 122. This ensures that the aiming point formed by the first intersecting beam emitted by the first light module along the light guide 122 after reflection by the reflector 2 coincides with the aiming point formed by the second intersecting beam emitted by the second light module along the light guide 122 after reflection by the reflector 2. This avoids deviation between the aiming points formed by the first and second light modules, thereby improving aiming accuracy.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
