Description

Technical Field

[0001] This utility model relates to the field of grid screen technology, and more specifically to a light source emitter for an outdoor grid screen. Background Technology

[0002] Currently, outdoor grid screens are widely used in many fields such as advertising displays, stage performances, and building facade decoration. Traditional outdoor grid screen light source emitters have some problems, such as uneven light distribution, low luminous efficiency, and when some light rays are emitted at an angle close to parallel to the plane, those rays are blocked by the plane and cannot be emitted, resulting in insufficient light utilization. This leads to insufficient brightness at the edges of the light source emitter, unclear image display, and is especially inconvenient for pedestrians to view from the side.

[0003] Therefore, how to provide a light source emitter that can make full use of the light emitted from the edge to improve the viewing effect and brightness is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides a light source emitter for an outdoor grid screen. The lens consists of two refractive surfaces, which can deflect light rays incident on the edge of the lens toward its center, so that this part of the light is fully utilized. The lens consists of three parts, and the first and third refractors are closer to the light source emitter than the second refractor. This allows some of the light rays that pass through the first and second refractors to be refracted toward the third refractor, converging at the third refractor, and then being refracted again together with the light rays that have been incident on the third refractor, thereby improving the brightness of the light and solving the problem of low luminous efficiency in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A light source emitter for an outdoor mesh screen, comprising:

[0007] A supporting housing, the supporting housing including a first plate and a second plate that are parallel to each other, the outer side of the first plate is a light source mounting surface, and the outer side of the second plate is an assembly surface;

[0008] A light source emitting light with wide-angle scattering, the light source emitting head being mounted on the light source mounting surface;

[0009] The lens covers the light source emitting head and is mounted on the light source mounting surface. The lens has a symmetrical structure and has an inner refractive surface and an outer refractive surface of the same shape to refract light rays incident on the edge of the lens before they are emitted. The lens consists of three refractive bodies from top to bottom along the axis of symmetry: refractive body one, refractive body two, and refractive body three. Refractive body one and refractive body three both contract toward the light source mounting surface, while refractive body two bulges away from the light source mounting surface so that some light rays converge at refractive body two, thereby increasing brightness.

[0010] According to the above technical solution, this utility model discloses a light source emitter for an outdoor mesh screen. The light source emitter head is installed on the light source mounting surface and located inside the lens. When the light source emitter head emits light, the light is emitted in a wide-angle scattering manner. Since the lens is a bilaterally symmetrical hemisphere containing two parallel layers of refractive surfaces, when the light is emitted from the light source emitter head, the light rays that are incident on the edge of the lens will be deflected towards the center of the lens, increasing the light-gathering range and allowing more light to be refracted and effectively utilized. The lens consists of three refractive bodies from top to bottom along the axis of symmetry: refractive body one, refractive body two, and refractive body three. Refractive bodies one and three both converge towards the light source mounting surface. When light enters the lens from the light source mounting surface... When light first comes into contact with the light source, it first encounters refractors one and three, which converge the light from both sides of the light source towards the center. After passing through refractors one and three, the light continues to propagate to refractor two. Refractor two bulges away from the light source mounting surface, allowing it to directly emit the light from the central area as well as the light refracted from refractors one and two. Through this lens structure, the wide-angle scattered light emitted from the light source is redistributed, making the light propagate more evenly in space, better controlling the direction of light propagation, and reducing light loss at the lens edge, thereby improving light utilization, enhancing the lighting effect, and thus improving the display effect of the outdoor grid screen.

[0011] Furthermore, the diameter of the sphere corresponding to the first refractor is larger than the diameter of the sphere corresponding to the third refractor.

[0012] The beneficial effects of adopting the above technical solution are as follows: The diameter of the sphere corresponding to refractor one is relatively large, that is, the arc surface of refractor one is relatively gentle, and the divergence effect of light is relatively strong. This allows the light that has been focused by refractor one to diffuse more evenly when it exits the lens, which helps to expand the illumination range and allows some light to be refracted to refractor two, thereby increasing the brightness of the light at that point. The diameter of the sphere corresponding to refractor three is relatively small, that is, the arc surface of refractor three is relatively steep, and the converging ability of light is strong. This allows the light to converge more quickly towards the optical axis of the lens, reducing the degree of divergence of light inside the lens. This allows the light to be more concentrated at refractor two, which is beneficial to improving the local brightness and making it easier for pedestrians to view the content of the grid screen from an upward angle, thus improving the clarity.

[0013] Furthermore, the mirror thickness of both the first and third refractors is less than that of the second refractor, and the thickness of both sides of the second refractor is the same as its center thickness.

[0014] The beneficial effects of adopting the above technical solution are as follows: the thinner thickness of refractive bodies one and three reduces light loss in these areas, allowing more light to effectively participate in the formation of optical effects. The thicker thickness of refractive body two ensures the concentration and enhancement of light in key areas, thereby improving the overall light efficiency. Furthermore, the thinner refractive bodies one and three can reduce reflection and absorption losses when light enters and leaves the lens, while the thicker thickness of refractive body two can better control the focusing of light, allowing light to be used more effectively for illumination or display.

[0015] Furthermore, the light source mounting surface is provided with a plurality of embedding grooves corresponding to the outer edge of the lens, and the edge end of the lens extends with a plurality of mounting protrusions corresponding to the plurality of embedding grooves, and the plurality of mounting protrusions are respectively fixedly embedded in the plurality of embedding grooves.

[0016] The beneficial effects of adopting the above technical solution are: the multiple mounting protrusions cooperate with the embedding groove, increasing the contact points and fixed positions between the lens and the light source mounting surface, making the lens more stable after installation, and less prone to loosening or displacement due to external force or vibration, ensuring that the lens maintains accurate optical position and angle during long-term use, thereby ensuring the stable optical performance of the light source emitter.

[0017] Furthermore, the support housing is hollow inside, and multiple heat dissipation holes are provided on the mounting surface.

[0018] The beneficial effects of adopting the above technical solution are: the hollow interior of the support housing forms a heat dissipation space, which, together with the heat dissipation holes on the assembly surface, can effectively promote air circulation, accelerate the dissipation of internal heat, help reduce the heat accumulation generated by components such as the light source emitter and lens during operation, thereby improving the heat dissipation efficiency of the entire light source emitter and ensuring the stability and reliability of the equipment during long-term operation.

[0019] Furthermore, a snap-fit ​​component is fixed on the assembly surface in a direction perpendicular to its surface.

[0020] The beneficial effects of adopting the above technical solution are: the snap-fit ​​component is vertically fixed on the assembly surface, providing a fast and convenient installation method. Installers can quickly connect the light source emitter to the wall or other supporting structure through the snap-fit ​​component without the need for traditional fixing methods such as bolts, thus saving installation time and labor costs.

[0021] Furthermore, wiring holes are provided at both the top and bottom ends of the support housing.

[0022] The beneficial effects of adopting the above technical solution are: the wiring hole provides a channel for the entry and exit of power lines, signal lines and other lines, which facilitates the connection of the light source emitter to the external power supply and control system, and ensures that the light source emitter can work normally.

[0023] Furthermore, an outdoor grid screen includes multiple light source emitters as described above, all of which are mounted on mounting brackets on the sidewall of the wall and are distributed in a grid pattern.

[0024] The beneficial effects of adopting the above technical solution are: the mounting bracket provides a stable and reliable support foundation for multiple light source emitters, ensuring that each light source emitter can work normally in the appropriate position; the grid-like distribution enables the light source emitters to form a uniform and regular arrangement on the plane, establishing an orderly display matrix, providing a spatial basis for displaying complete image or text information.

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] This utility model discloses a light source emitter for an outdoor grid screen, including a supporting shell 1. The supporting shell 1 includes a first plate and a second plate that are parallel to each other. The outer side of the first plate is a light source mounting surface 11, and the outer side of the second plate is an assembly surface 12. A light source emitter 3 that emits light with wide-angle scattering is mounted on the light source mounting surface 11. A lens 2 covering the light source emitter 3 is mounted on the light source mounting surface 11. The lens 2 has a left-right symmetrical structure and has an inner refractive surface 24 and an outer refractive surface of the same shape to refract light rays incident on the edge of the lens 2 before they are emitted. The lens 2 has, along the axis of symmetry, a refractive body 1 21, a refractive body 22, and a refractive body 3 23 from top to bottom. The refractive bodies 1 21 and 23 both contract toward the light source mounting surface 11, while the refractive body 22 bulges away from the light source mounting surface 11 so that some light rays are concentrated at the refractive body 22, thereby increasing the brightness.

[0036] Specifically, the light source emitter 3 uses RGB LEDs, and can be sized in three sizes: 30×30mm, 35×35mm, and 50×50mm. These three types of RGB LEDs are relatively small, which can better adapt to the size and spacing requirements of the mesh screen lens. They can be closely arranged within the pixel units of the mesh screen to achieve a high-density pixel layout, thereby improving the resolution and image clarity of the display screen. They also have good optical performance, namely high brightness, high luminous efficiency, and good color rendering, which can provide the mesh screen with a bright, clear, and color-accurate image display effect, meeting the high-quality display requirements of the mesh screen in various application scenarios.

[0037] In a specific embodiment of the refractive layout of lens 2 in this utility model, to improve the brightness of the local area viewed from below, the diameter of the sphere corresponding to refractive body 1 21 is larger than the diameter of the sphere corresponding to refractive body 3 23. The larger diameter of the sphere corresponding to refractive body 1 21 means that the arc surface of refractive body 1 21 is relatively gentle, resulting in a stronger divergence effect on light. This allows the light, after being focused by refractive body 1 21, to diffuse more evenly when exiting lens 2, helping to expand the illumination range and allowing some light to be refracted to refractive body 2 22, thus increasing the brightness at that location. The smaller diameter of the sphere corresponding to refractive body 3 23 means that the arc surface of refractive body 3 23 is relatively steep, resulting in a stronger converging ability on light. This allows light to converge more quickly towards the optical axis of the lens, reducing the degree of divergence within lens 2. This allows the light to be more concentrated at refractive body 2 22, improving local brightness and making it easier for pedestrians to view the content of the grid screen from below, thus improving clarity.

[0038] In this invention, specific embodiments regarding the dimensions of lens 2 are described. The thickness of refractive bodies 1 (21) and 3 (23) is less than that of refractive body 2 (22), and the thickness of both edges of refractive body 22 is the same as its center thickness. The thinner thickness of refractive bodies 1 (21) and 3 (23) reduces light loss in these areas, allowing more light to effectively participate in the formation of the optical effect. The thicker thickness of refractive body 2 (22) ensures the concentration and enhancement of light in key areas, thereby improving the overall light efficiency. Furthermore, the thinner refractive bodies 1 (21) and 3 (23) reduce reflection and absorption losses when light enters and exits lens 2, while the thicker refractive body 2 (22) better controls the focusing of light, allowing the light to be used more effectively for illumination or display.

[0039] Specifically, the thickness of the second refractive body 22 is 3mm, corresponding to a vertical distance of 6.5mm between the inner center of lens 2 and the light source mounting surface 11, and a vertical distance of 9.5mm between the outer center of lens 2 and the light source mounting surface 11. The major axis distance of the inner refractive surface 24 corresponding to the cross-section of the light source mounting surface 11 is 17.3mm, and the minor axis distance is 13mm. The major axis distance of the outer refractive surface 26 corresponding to the cross-section of the light source mounting surface 11 is 19.3mm, and the minor axis distance is 19mm. This allows lens 2 to achieve a light-gathering effect in the vertical direction and a light-scattering effect in the horizontal direction. This improves the projection effect, ensuring that even when the pedestrian's line of sight is close to the same plane as the grid display screen, the image at a horizontal 180-degree angle can still be clearly seen through lens 2.

[0040] In the above embodiment, to facilitate the installation of the lens 2, a plurality of embedding slots 14 are provided on the light source mounting surface 11 corresponding to the outer edge of the lens 2. A plurality of mounting protrusions 25 extend from the edge of the lens 2 corresponding to the plurality of embedding slots 14, and the plurality of mounting protrusions 25 are respectively fixedly embedded in the plurality of embedding slots 14. The plurality of mounting protrusions 25 cooperate with the embedding slots 14, increasing the contact points and fixing positions between the lens 2 and the light source mounting surface 11, making the lens 2 more stable after installation, and less prone to loosening or displacement due to external forces or vibrations. This ensures that the lens 2 maintains an accurate optical position and angle during long-term use, thereby ensuring the stable optical performance of the light source emitter.

[0041] In the above embodiment, to ensure stable operation of the light source emitter 3 inside, the support housing 1 is hollow, and multiple heat dissipation holes 121 are provided on the mounting surface 12. The hollow interior of the support housing 1 forms a heat dissipation space, which, together with the heat dissipation holes 121 on the mounting surface, can effectively promote air circulation and accelerate the dissipation of internal heat. This helps to reduce the heat accumulation generated by components such as the light source emitter 3 and lens 2 during operation, thereby improving the heat dissipation efficiency of the entire light source emitter and ensuring the stability and reliability of the equipment during long-term operation.

[0042] In the above embodiment, a snap-fit ​​component 122 is fixed on the assembly surface 12 in a direction perpendicular to its surface. The snap-fit ​​component 122 is vertically fixed on the assembly surface 12, providing a quick and convenient installation method. Installers can quickly connect the light source emitter to the wall or other supporting structure through the snap-fit ​​component without using traditional fixing methods such as bolts, saving installation time and labor costs.

[0043] In the above embodiment, to facilitate the series connection of multiple light source emitters and their connection to the control system, wiring holes 13 are provided through both the top and bottom ends of the support housing 1. The wiring holes 13 provide channels for the entry and exit of power lines, signal lines, and other lines, facilitating the connection of the light source emitters to external power supplies and control systems, and ensuring that the light source emitters can work normally.

[0044] In the above embodiments, multiple light source emitters are mounted on mounting brackets on the sidewall of the wall and arranged in a grid pattern to form an outdoor grid screen. The mounting brackets provide a stable and reliable support foundation for the multiple light source emitters, ensuring that each light source emitter can work normally in the appropriate position; the grid pattern allows the light source emitters to form a uniform and regular arrangement on the plane, establishing an orderly display matrix and providing a spatial basis for displaying complete image or text information.

[0045] The working principle of the light source emitter of this utility model is as follows:

[0046] This outdoor grid screen light source emitter achieves efficient light control through a uniquely designed lens structure. The lens consists of three refractors, which are symmetrical vertically and relatively thin, allowing light to quickly enter and initially converge at the thicker refractor, refractor 2, achieving light focusing and increasing brightness. The light then diverges wide-angle to the left and right via refractor 3, forming a 160-degree vertical and 180-degree horizontal illumination. Simultaneously, the light source emitter is located inside the lens, and its wide-angle light scattering, combined with the lens's optical design, ensures uniform light distribution. Furthermore, the supporting housing, mounting surfaces, and heat dissipation holes ensure the stability and heat dissipation of the equipment, while the snap-fit ​​connectors and wiring holes improve installation efficiency and wiring management. These multiple components work together to ensure the high performance and reliability of the outdoor grid screen.

[0047] Therefore, this lens structure redistributes the wide-angle scattered light emitted by the light source emitter, making the light propagate more evenly in space, better controlling the direction of light propagation, and reducing light loss at the upper and lower edges of the lens, thereby improving the utilization rate of light, enhancing the lighting effect, and thus improving the display effect of the outdoor grid screen.
