Description

Technical Field

[0001] This utility model relates to the field of LED light source module technology, and in particular to a modular multi-light source light-shielding and anti-glare structure and a light source module using the structure. Background Technology

[0002] While LED light source modules are widely used in public lighting scenarios due to their high luminous efficiency and energy-saving advantages, the glare caused by their high brightness severely affects spatial positioning performance. Direct glare can cause temporary visual impairment, while indirect glare creates a light curtain effect through environmental reflection, leading to reduced visibility of obstacles, signs, and paths for pedestrians or drivers in public areas (such as roads, squares, and transportation hubs), and even causing safety accidents due to visual misalignment. This "poor positioning" problem has become a prominent bottleneck restricting the in-depth application of LED lighting in complex public scenarios.

[0003] Existing anti-glare structures mostly rely on diffusers or light shields, which limit the angle of light diffusion through geometric blocking to reduce the interference of stray light on the surrounding environment. However, they have the following problems:

[0004] (1) Traditional light shields, honeycomb baffles and other structures require multiple physical barriers around the light source, which leads to volume expansion. The excessive light shielding structure forces the overall size of the lamp to increase.

[0005] (2) In multi-source matrix modules, traditional shading components are difficult to match the spatial position of each light source in sync, which weakens the ability to suppress far-field light. Furthermore, the overlap of light spots and cross-interference of diffuse reflection between adjacent light sources cannot be eliminated, which exacerbates the disorder of the light environment and significantly reduces the reliability of positioning.

[0006] The aforementioned shortcomings make it difficult for existing technologies to achieve synergistic optimization of precise glare suppression and spatial positioning performance in complex lighting scenarios. Utility Model Content

[0007] To address the problems of existing technologies, this utility model provides a modular multi-source light-shielding and anti-glare structure and a light source module. This structure physically limits the light diffusion angle by using light-blocking panels arranged around each light source, precisely constraining the illumination area while suppressing stray light overflow, achieving an integrated design of high-precision localized lighting and low glare.

[0008] The specific technical solution of this utility model is as follows:

[0009] This utility model provides a modular multi-source light-shielding and anti-glare structure for a light source module. Multiple light sources are arranged in a matrix on the light-emitting surface of the light source module. The modular multi-source light-shielding and anti-glare structure includes a substrate mounted on the light-emitting surface of a light source module using a detachable connection mechanism. Multiple light sources are arranged in a matrix on the light-emitting surface of the light source module. The substrate has multiple through holes, each corresponding to at least one light source in the light source module. The opening size of each through hole is adapted to the outer dimensions of the corresponding light source. The substrate is provided with a light-blocking mechanism, which includes a light-blocking panel fixed to the surface of the substrate and arranged vertically or inclined along at least one side of the circumferential edge of the through hole.

[0010] In some preferred technical solutions, the through hole is a small through hole opened for each light source on the light source module; or, several adjacent light sources in the same horizontal row, the same vertical column or the same diagonal direction are combined into a light source group, and the opening size of each through hole is adapted to the outer contour size of the corresponding light source group.

[0011] In some preferred technical solutions, the light-blocking mechanism includes two configurations: a single-sided light-blocking unit and a ring-shaped light-blocking unit;

[0012] The single-sided light-blocking unit is a configuration in which a light-blocking panel is provided on one side edge of a single through hole, or on the same side edge of multiple through holes linearly arranged along the length / radial direction of the substrate.

[0013] The annular light-blocking unit is a configuration in which multiple light-blocking panels surround a single through-hole, or surround a group of through-holes arranged linearly along the length / radial direction of the substrate to form a multi-faceted light-blocking frame.

[0014] In a preferred embodiment, the light-blocking mechanism is a four-sided light-blocking frame formed by four light-blocking panels surrounding a group of through holes arranged linearly along the radial direction of the substrate, wherein the number of through holes in the group of through holes is two or more.

[0015] The four-sided light-blocking frame is formed by sequentially connecting and enclosing a first trapezoidal light-blocking surface, a first side trapezoidal light-blocking surface, a second trapezoidal light-blocking surface, and a second side trapezoidal light-blocking surface around the through-hole group. The first trapezoidal light-blocking surface and the second trapezoidal light-blocking surface have the same shape and size and are symmetrically arranged. The first side trapezoidal light-blocking surface and the second side trapezoidal light-blocking surface are symmetrically arranged.

[0016] The axial heights of the first trapezoidal light-blocking surface, the second trapezoidal light-blocking surface, the first side trapezoidal light-blocking surface, and the second side trapezoidal light-blocking surface are all equal.

[0017] Furthermore, the upper edges of the first trapezoidal light-blocking surface and the first side trapezoidal light-blocking surface respectively extend outward along their planar direction to form rectangular extension portions.

[0018] In some preferred technical solutions, the tilt angles formed between the first trapezoidal light-blocking surface, the first side trapezoidal light-blocking surface, the second trapezoidal light-blocking surface, and the second side trapezoidal light-blocking surface and the corresponding non-through-hole side substrate surface respectively satisfy any of the following conditions:

[0019] The first trapezoidal light-blocking surface, the first side trapezoidal light-blocking surface, the second trapezoidal light-blocking surface, and the second side trapezoidal light-blocking surface each form an equal tilt angle with the corresponding non-through-hole side substrate surface;

[0020] The first trapezoidal light-blocking surface and the second trapezoidal light-blocking surface form equal tilt angles α with the substrate surface on the corresponding non-through-hole side, and the first trapezoidal light-blocking surface and the second trapezoidal light-blocking surface form equal tilt angles β with the substrate surface on the corresponding non-through-hole side, while the tilt angles α and β are not equal.

[0021] The first trapezoidal light-blocking surface and the second trapezoidal light-blocking surface form equal tilt angles with the substrate surface on the corresponding non-through-hole side, and the first trapezoidal light-blocking surface and the second trapezoidal light-blocking surface form unequal tilt angles with the substrate surface on the corresponding non-through-hole side.

[0022] In a preferred embodiment, the substrate has screw holes at both ends along its length, and the substrate is connected to the light source module by fasteners passing through the screw holes; a pair of vertical cuts are provided on the first trapezoidal light-blocking surface and / or the second trapezoidal light-blocking surface corresponding to the axial projection area of ​​the screw holes, and the bottom of the same pair of vertical cuts extends toward the opposing surfaces to form an arc-shaped segment.

[0023] In a preferred embodiment, the substrate has vertically downward bent edges on both sides of its axial direction that cover the sidewalls of the light source module; and a display through hole is provided on the substrate at the position corresponding to the light source illumination direction marking on the upper surface of the light source module.

[0024] Both the substrate and the light-blocking mechanism are made of aluminum alloy, black glass fiber reinforced PC, or ABS plastic.

[0025] The second aspect of this utility model also discloses a light source module, including a heat sink, a circuit board attached to the upper surface of the heat sink, a cover plate covering the circuit board, and a fixed frame connected to the heat sink and pressing the cover plate onto the heat sink. A plurality of LED beads are disposed on the upper surface of the circuit board, and an optical lens covering the LED beads is formed on the cover plate. Each LED bead and its covering optical lens constitute a light source. The module also includes the aforementioned modular multi-light source light-shielding and anti-glare structure. The substrate is mounted on the cover plate of a light source module using a detachable connection mechanism.

[0026] In some preferred technical solutions, the detachable connection mechanism includes at least one connection structure selected from threaded fastening components, elastic snap-fit ​​components, and pressing components; the threaded fastening component includes bolt holes and matching fasteners corresponding to the edge of the substrate and the fixing frame of the light source module; the elastic snap-fit ​​component includes a snap hook on the periphery of the substrate and a snap groove corresponding to the fixing frame of the light source module; the pressing component includes a pressure strip along the edge of the substrate and a limiting groove that cooperates with the fixing frame of the light source module.

[0027] Based on the above-mentioned principles of the utility model, the beneficial effects of this utility model are as follows:

[0028] This utility model's modular multi-source light-shielding and anti-glare structure physically isolates the light paths of adjacent light sources by independently equipping each light source with a light-blocking mechanism. This directly blocks light spot overlap and diffuse reflection interference, significantly improving the luminous purity of the local lighting area. Compared to traditional large light-blocking covers, the one-to-one light-blocking design eliminates edge light leakage caused by tolerance accumulation in multi-source light source modules, preventing the generation of secondary glare sources.

[0029] The modular multi-source light-shielding and anti-glare structure of this utility model has good geometric adaptability. The tilt angle, vertical height and other parameters of the light-shielding mechanism can be customized. By physically blocking the light source to limit the divergence angle, the light diffusion range is constrained to the target area, thus achieving precise control of light distribution.

[0030] This utility model's light-blocking mechanism and substrate are quickly connected to the light source module via a detachable mechanism. The light-blocking mechanism is a split design, positioned close to each through-hole, reducing the module's size. This avoids the bulky problem of traditional integrated light shields and is suitable for compact space deployment. This design ensures independent maintainability of the optical path control components (such as cleaning or replacing the light-blocking mechanism) without affecting the heat dissipation path of the light source itself, thus balancing functionality and engineering practicality.

[0041] This utility model provides a modular multi-source light-shielding and anti-glare structure and a light source module. It adapts the position of the light source through the through holes on the detachable substrate, and sets a vertical or inclined light-blocking mechanism along the edge of the through hole. The split design of the light-blocking mechanism reduces the module volume, achieving a compact size and precise shading. The height and tilt angle of the light-blocking mechanism can be customized to constrain the light diffusion range within the target area.

[0042] The following embodiments further illustrate the content of this utility model, but should not be construed as limiting the scope of this utility model. Any modifications or substitutions made to the methods, steps, or conditions of this utility model without departing from its spirit and essence are within the scope of this utility model.

[0043] refer to Figure 1 , Figure 2This utility model discloses a modular multi-source light-shielding and anti-glare structure for a light source module, comprising a substrate 10 mounted on the light-emitting surface of a light source module 2 using a detachable connection mechanism. Multiple light sources 20 are arranged in a matrix on the light-emitting surface of the light source module 2. The substrate 10 has multiple through holes 11, each through hole 11 corresponding to at least one light source 20 in the light source module 2. The opening size of each through hole 11 is adapted to the outer dimensions of the corresponding light source 20. The light source whose opening size is adapted to the through hole 11 should be understood as at least one light source 20. When hole 11 corresponds to two or more light sources, the opening size of the through hole 11 should be adapted to the outer dimension range included by the two or more light sources; the opening size of the through hole 11 should ensure that the corresponding light source 20 is fully exposed and the orthographic projection area of ​​the corresponding light source 20 in the normal direction of the substrate plane is not blocked by the substrate 10; the substrate 10 is provided with a light blocking mechanism 12, the light blocking mechanism 12 includes a light blocking panel fixed to the surface of the substrate 10 and arranged vertically or inclinedly along at least one side of the circumferential edge of each through hole 11.

[0044] This structure replaces the traditional external light-shielding grille with a detachable substrate, reducing the overall thickness of the module. It is particularly suitable for embedded installations or space-constrained scenarios, avoiding positioning deviations caused by lamp misalignment. The substrate design in this structure can handle multiple light sources simultaneously, with each through-hole corresponding to one or more light sources. The light-blocking panel independently acts to physically block the light path of each light source, preventing light spot overlap and diffuse reflection cross-interference between adjacent light sources.

[0045] The through-hole 11 structure includes two technical solutions; the first is that the through-hole 11 is a small through-hole opened for each light source on the light source module 2, as shown in the reference. Figure 1 The number of small through holes is equal to the number of light sources 20. The opening shape and size of each small through hole match the outer contour of the corresponding light source 20, ensuring that the light source is fully exposed and not blocked by the substrate 10. The second method involves grouping several adjacent light sources 20 in the same horizontal row, vertical column, or diagonal direction into a light source group. For example, two light sources 20 side-by-side form a light source group. (Refer to...) Figure 3 The opening size of each of the vias 11' is adapted to the outer contour size of the corresponding light source group, and the opening size of each via 11' on the substrate 10 is adapted to the total outer contour size of the entire light source group, that is, to cover the maximum boundary range of all combined light sources.

[0046] The light-blocking mechanism 12 is used to physically block stray light from the side of the light source, and its configuration is designed according to the requirements of actual application scenarios. The light-blocking mechanism 12 mainly includes two configurations: a single-sided light-blocking unit 120 and a ring-shaped light-blocking unit 130.

[0047] The single-sided light-blocking unit 120 is configured such that a light-blocking panel is provided on one side edge of a single through-hole, or on the same side edge of multiple through-holes linearly arranged along the length / radial direction of the substrate 10. Its basic form is as follows:

[0048] The single-sided light-blocking unit 120 is a light-blocking panel disposed on one edge of a single through-hole 11'. In this case, the light-blocking panels for each through-hole 11' are discontinuous. (Refer to...) Figure 3 The light-blocking panel only blocks one edge of each 11' through-hole, such as the left, right, top, or bottom edge;

[0049] Alternatively, the single-sided light-blocking unit 120' is a light-blocking panel disposed on the same side edge of a plurality of through holes 11 linearly arranged along the length or radial direction of the substrate 10, as shown in the reference. Figure 4 The light-blocking panel extends continuously along the same side edge of the through-hole 11 in the same linear direction, forming a long strip-shaped light-blocking panel. The light-blocking panel can be a vertical plate or a light-blocking plate with a certain tilt angle. The single-sided light-blocking mechanism reduces stray light diffusion from non-target directions and eliminates glare by physically blocking lateral light from the light source. It should be noted that the radial direction mentioned in this text refers to the direction perpendicular to the long side of the substrate.

[0050] The annular light-blocking unit 130 is a multi-faceted light-blocking frame formed by multiple light-blocking panels surrounding a single through-hole 1, or surrounding a group of through-holes linearly arranged along the length / radial direction of the substrate. The through-hole group includes at least two through-holes 11. Its basic form is as follows:

[0051] The annular light-blocking unit 130 is a closed frame structure in which multiple light-blocking surfaces surround a single through hole 11 to form a multi-faceted light-blocking frame;

[0052] Alternatively, a closed frame configuration of a multifaceted light-blocking frame formed around the periphery of a group of through holes linearly arranged along the length or radial direction of the substrate 10, refer to... Figure 1 The annular light-blocking unit 130 surrounds the two through holes 11 that are linearly arranged along the radial direction of the substrate 10.

[0053] In addition to forming a multi-faceted light-blocking frame structure, it can also be configured with a circular or other curved cross-section as needed, while ensuring its functionality. The annular frame structure enclosed by the annular light-blocking unit physically blocks the diffusion range of light that would otherwise be scattered in all directions to the effective illumination area, reducing stray light loss in non-target directions, and blocking the propagation of light from the light source in unexpected directions by setting the tilt angle of each light-blocking panel.

[0054] In some specific examples of this utility model, the light-blocking mechanism uses a ring-shaped light-blocking unit 130, specifically a four-sided light-blocking frame formed by four light-blocking panels surrounding a group of through holes linearly arranged along the radial direction of the substrate. The number of through holes in the group is two; the spacing between the two through holes is designed according to the optical requirements of the light source module. Specifically, such as... Figure 5a The four-sided light-blocking frame is formed by sequentially connecting and enclosing a first trapezoidal light-blocking surface 1301, a first side trapezoidal light-blocking surface 1302, a second trapezoidal light-blocking surface 1303, and a second side trapezoidal light-blocking surface 1304 around the through-hole group. The first trapezoidal light-blocking surface 1301 and the second trapezoidal light-blocking surface 1303 have the same shape and size and are symmetrically arranged, while the first side trapezoidal light-blocking surface 1302 and the second side trapezoidal light-blocking surface 1304 are symmetrically arranged.

[0055] The axial heights of the first trapezoidal light-blocking surface 1301, the first side trapezoidal light-blocking surface 1302, the second trapezoidal light-blocking surface 1303, and the second side trapezoidal light-blocking surface 1304 are set according to the application scenario, and can be set to be all equal, all unequal, or partially equal. The tilt angles formed between the first trapezoidal light-blocking surface 1301, the first side trapezoidal light-blocking surface 1302, the second trapezoidal light-blocking surface 1303, and the second side trapezoidal light-blocking surface 1304 and the corresponding non-through-hole side substrate surface are set according to the application scenario, and can be set to be all equal, all unequal, or partially equal tilt angles. That is, the axial heights of the first trapezoidal light-blocking surface 1301, the first side trapezoidal light-blocking surface 1302, the second trapezoidal light-blocking surface 1303, and the second side trapezoidal light-blocking surface 1304 of the four-sided light-blocking frame and the tilt angles formed between them and the corresponding non-through-hole side substrate surfaces are non-limiting design parameters, and their specific values ​​can be dynamically adjusted according to the optical requirements, space constraints, and performance indicators of the actual application scenario. Design logic: Glare level control is achieved by increasing the height of the light-blocking surface or adjusting the tilt angle of the light-blocking surface to enhance the physical blocking effect of direct light from a specific viewing angle; Light distribution pattern: The tilt angle formed between the light-blocking surface and the substrate surface on the non-through-hole side affects the light diffusion range. A small tilt angle (such as 30°) can expand the blocking coverage area, while a large angle (such as 75°) can reduce the light diffusion angle.

[0056] As a light-blocking structure for a light source module with multiple light sources, to ensure the consistency of the blocking boundaries of the multiple light sources, the four rectangular inclined surfaces can be defined as follows: The axial heights of the first trapezoidal light-blocking surface, the first side trapezoidal light-blocking surface, the second trapezoidal light-blocking surface, and the second side trapezoidal light-blocking surface satisfy any of the following conditions:

[0057] (1) The axial height of the first trapezoidal light-blocking surface, the axial height of the second trapezoidal light-blocking surface, the axial height of the first side trapezoidal light-blocking surface and the axial height of the second side trapezoidal light-blocking surface are all equal, the height of the light-blocking surface in each direction is consistent, the blocking intensity in each direction is balanced, and a uniform light spot is formed.

[0058] (2) The axial heights of the first trapezoidal light-blocking surface and the second trapezoidal light-blocking surface are equal, and the axial heights of the first side trapezoidal light-blocking surface and the second side trapezoidal light-blocking surface are equal, while the axial heights of the trapezoidal light-blocking surface and the side trapezoidal light-blocking surface are not equal. See also Figure 6a and Figure 6b The upper edges of the first trapezoidal light-blocking surfaces 1301' and 1301'' and the second trapezoidal light-blocking surfaces 1303' and 1303'' respectively extend outward along their planar direction to form rectangular extension portions 1305' and 1305''. For example, the axial height of both the first and second trapezoidal light-blocking surfaces is 3cm, and the axial height of both the first and second side trapezoidal light-blocking surfaces is 2cm. The higher trapezoidal light-blocking surfaces enhance the constraint on light diffusion in the illumination direction, while the lower side trapezoidal light-blocking surfaces allow for partial lateral light diffusion to meet wide-area lighting requirements.

[0059] In a further definition, the tilt angles formed between the first trapezoidal light-blocking surface, the first side trapezoidal light-blocking surface, the second trapezoidal light-blocking surface, and the second side trapezoidal light-blocking surface and the corresponding non-through-hole side substrate surface satisfy any of the following conditions:

[0060] (1) The first trapezoidal light-blocking surface, the first side trapezoidal light-blocking surface, the second trapezoidal light-blocking surface and the second side trapezoidal light-blocking surface each form an equal tilt angle with the corresponding non-through hole side substrate surface.

[0061] (2) The first trapezoidal light-blocking surface and the second trapezoidal light-blocking surface form equal tilt angles α with the substrate surface on the corresponding non-through hole side, and the first trapezoidal light-blocking surface and the second trapezoidal light-blocking surface form equal tilt angles β with the substrate surface on the corresponding non-through hole side. Meanwhile, the tilt angles α and β are not equal. This solution can enhance the physical shielding effect on non-target areas for specific ambient light interference directions (such as streetlights needing to shield the illumination of roadside residential areas).

[0062] (3) The first trapezoidal light-blocking surface and the second trapezoidal light-blocking surface form equal tilt angles with the substrate surface on the corresponding non-through-hole side, and the first trapezoidal light-blocking surface and the second trapezoidal light-blocking surface form unequal tilt angles with the substrate surface on the corresponding non-through-hole side. By combining the angles of the asymmetrical trapezoidal light-blocking surfaces, the light diffusion range can be constrained to form a shielding boundary suitable for irregularly shaped illumination areas; for multi-view application scenarios (such as multi-seat lighting in stadiums), the differentiated tilt angle settings achieve glare suppression at specific viewing angles.

[0063] The substrate of this invention is connected to the light source module using a detachable connection mechanism. In one example, the substrate is connected to the light source module at both ends along its length using screw holes and fasteners. A pair of vertical slits are provided on the first trapezoidal light-blocking surface and / or the second trapezoidal light-blocking surface corresponding to the axial projection area of ​​the screw holes. (Reference) Figure 2 A pair of vertical slits 14 are provided on the first or second trapezoidal light-blocking surface corresponding to the axial projection area of ​​the screw hole 13. The bottom of the same pair of vertical slits 14 extends towards the opposing surface to form an arc-shaped segment 15. The substrate is connected to the frame of the light source module by fasteners 16. When the angle between the first or second trapezoidal light-blocking surface and the substrate on the non-through-hole side is a small acute angle, the orthographic projection of the first or second trapezoidal light-blocking surface partially overlaps with the axial projection area of ​​the screw hole 13. At this time, the disassembly and assembly operation is partially blocked by the substrate, making the operation difficult. By providing a pair of vertical slits 14 on the first or second trapezoidal light-blocking surface, when the substrate 10 needs to be disassembled or assembled, an inward pressing action can be performed before the pair of vertical slits 14 to push the substrate 10 between the vertical slits 14 apart, and then the disassembly and assembly operation can be performed.

[0064] The substrate 10 has vertically downward bent edges 17 on both axial sides to cover the sidewalls of the light source module. To further ensure the substrate is securely installed, the edges 17 and the corresponding sidewalls of the light source module can be connected by a locking block or a slot or by screw fastening.

[0065] The substrate 10 is generally flat, but its shape can be changed according to the shape of the corresponding assembled light source module to adapt to the specific light source module; in one example, refer to Figure 7 and Figure 8 To accommodate the convex cuboid cover plate of the light source module, the substrate 10 has downward folded edges on all four sides to form a cuboid structure with an open bottom. The entire substrate wraps around the cuboid cover plate of the light source module. At this time, secondary folded edges 10' are formed by horizontally extending outward on both sides of the bottom of the cuboid of the substrate 10. Screw holes are provided at the secondary folded edges 10' to fasten to the frame of the light source module.

[0066] The example further refines the structure of the substrate 10. A display through-hole 18 is provided on the substrate 10 at the position corresponding to the light source illumination direction marking on the upper surface of the light source module. (Refer to...) Figure 2 The triangular display through-hole 18 shown makes it easy for installers to clearly see the marking information. In addition, the substrate 10 has arc-shaped inner grooves 19 at the middle of both ends of its edges to accommodate the mounting screws of the light source module frame.

[0067] The second aspect of this utility model also discloses a light source module with the above-mentioned modular multi-light source light-shielding and anti-glare structure, see reference. Figure 9As shown, the light source module 2 includes a heat sink 21, a circuit board 22 attached to the upper surface of the heat sink 21, a cover plate 23 covering the circuit board 22, and a fixed frame 24 connected to the heat sink 21 and fixing the cover plate 23 to the heat sink 21. Multiple LED beads are disposed on the upper surface of the circuit board 22, and an optical lens covering the LED beads is formed on the cover plate 23. Each LED bead and the optical lens covering it form a light source 20. It also includes the above-mentioned modular multi-light source light-shielding and anti-glare structure 1. The substrate 10 is installed on the cover plate 23 of a light source module 2 using a detachable connection mechanism.

[0068] The detachable connection mechanism may employ a mechanical structure conventionally used in the art, specifically including at least one connection structure selected from threaded fastening components, resilient snap-fit ​​components, and clamping components. (See reference) Figure 9 The threaded fastening assembly includes bolt holes and matching fasteners corresponding to the edges of the substrate 10 and the fixing frame 24 of the light source module. In other embodiments, the elastic snap-fit ​​assembly includes a snap hook disposed on the periphery of the substrate and a snap groove corresponding to the fixing frame of the light source module; the pressing assembly includes a pressing strip disposed along the edge of the substrate and a limiting groove that cooperates with the fixing frame of the light source module.

[0069] It should be noted that the overall shape of the modular multi-source light-shielding and anti-glare structure can be adapted to the shape and size of the emitting surface of one light source module of the lamp; or it can be adapted to the shape and size of the emitting surfaces of all light source modules of the lamp. The latter can be understood as follows: when the lamp has only one light source module, the anti-glare structure is short, and the overall shape of the modular multi-source light-shielding and anti-glare structure is adapted to the emitting surface of one light source module; when the lamp has two or more light source modules, the anti-glare structure is long, ensuring that the overall shape of the modular multi-source light-shielding and anti-glare structure is adapted to the shape after the emitting surfaces of the corresponding multiple light source modules are connected. Figure 10a , Figure 10b .

[0070] It should also be noted that the substrate of this modular multi-source light-shielding and anti-glare structure needs to have sufficient mechanical strength to support the light-blocking mechanism, and also needs heat dissipation, as it is close to the light source module, and the light source usually generates heat. The light-blocking panel needs to have good shading performance and reduce reflected glare through surface anti-glare treatment (such as frosted texture or light-absorbing coating). Both the substrate and the light-blocking mechanism can be made of aluminum alloy or high-temperature resistant engineering plastics (such as black PC, PBT, PA, ABS, etc.), possessing sufficient mechanical strength and heat dissipation, while being easy to process and install. When the substrate and the light-blocking mechanism are aluminum alloys, they are connected by welding; when the substrate is PC or glass fiber reinforced PC, the light-blocking panel is black PC or light-absorbing PBT, and is integrally molded by injection molding or mechanically connected. In other solutions, the substrate is made of aluminum alloy and the light-blocking panel is made of plastic. In this case, welding is not applicable, and the light-blocking panel is fixed by clips or glue.

[0071] This utility model features a light source module with a modular multi-source light-shielding and anti-glare structure. Utilizing its physical blocking function, it effectively suppresses glare and restricts the light diffusion range. The asymmetrical light-blocking structure further enhances light blocking in non-target areas. For example, in street lighting applications, the asymmetrical light-blocking structure prevents light from reaching roadside residential areas while ensuring effective road lighting.
