Description

Technical Field

[0001] This invention relates to the field of lighting devices, specifically to a modular stadium light with adjustable illumination angle and anti-glare properties. Background Technology

[0002] As the core lighting equipment of a stadium, stadium lights not only need to provide the field with high illuminance, high uniformity and low glare lighting effects, but also need to be able to flexibly adapt to the lighting effect requirements of different sports such as basketball, tennis, badminton and training scenarios; however, with the large-scale deployment of stadium lights in cities, the light pollution problem caused by stadium lights is increasing day by day.

[0003] Currently, stadium lights with angle adjustment functions can only achieve a wide range of pitch or horizontal rotation of the entire light, but cannot independently and precisely adjust the local illumination direction of multiple light-emitting modules inside the light fixture. This results in dark areas or excessive overlap in the illuminated area, failing to meet the strict requirements of professional competitions for the shape of the light spot and the transition of the boundary.

[0004] Secondly, in pursuit of high luminous flux, people often adopt symmetrical optical designs at the light-emitting end of stadium lights. This means that the technical defects in glare control of the lights still exist. A large amount of light is scattered directly upwards or to the sides, which not only causes serious glare, affecting the athletes' vision and broadcast quality, but also produces upward light spill, exacerbating light pollution in the night sky and seriously affecting people living in high-rise buildings around the stadium.

[0005] In addition, when adjusting the illumination angle of existing stadium lights, operators usually rely on their own operating experience or measuring tools to know the angle change. The stadium lights lack precise calibration and marking structures, which leads to poor consistency of illumination direction among the light sources when installing lights with multiple light source combinations. Furthermore, the illumination angle adjustment process is cumbersome and inefficient. Summary of the Invention

[0006] To address the technical deficiencies in the prior art, this invention proposes a modular anti-glare stadium light with adjustable illumination angle, solving the aforementioned technical problems and meeting practical needs. The specific technical solution is as follows: A modular, anti-glare stadium light with adjustable illumination angle, comprising: The support module consists of a fixed frame and an adjustable frame. The fixed frame has an adjustable frame at the end that is not fixed to an external object. The adjustable frame is connected to the left and right sides of the fixed frame through a first adjusting structure, and its tilt angle relative to the fixed frame is adjusted by the first adjusting structure. A light source module is disposed between two adjustment frames, and the number of such modules is at least one. The left and right sides of the light source module are connected to the adjustment frames through a second adjustment structure, and the tilt angle of the module relative to the adjustment frame is adjusted by the second adjustment structure. A light-shielding module is connected to the light-emitting end of the light source module and is distributed at at least two positions in the light source module. The light-shielding module reflects light emitted from the surface of the light-emitting end with an upward component relative to the horizontal plane through a portion distributed at any position in the light source module or through all portions distributed in the light source module, and the light is emitted in any direction where the surface of the light-shielding module above the light emission point of the light-emitting end forms an angle greater than 0° with the horizontal direction. The calibration components are distributed on the outside of the first adjustment structure, the outside of the second adjustment structure, and on the top of the light source module. They provide a visual reference when the first adjustment structure adjusts the tilt angle of the adjustment frame relative to the fixed frame, when the second adjustment structure adjusts the tilt angle of the light source module relative to the adjustment frame, and when the light source module is irradiated at an absolutely parallel or specific angle.

[0007] As a further improvement of the present invention, the first adjusting structure includes a first connecting hole, a first shaft-like connector, a second connecting hole, a third connecting hole, and a second shaft-like connector. The fixed frame, both at its non-fixed ends to the external object and the adjusting frame, are provided with first connecting holes. The adjusting frame is movably connected to the fixed frame via the first shaft-like connectors to the two first connecting holes whose central axes are on the same straight line. The fixed frame has a second connecting hole with an arc-shaped cross-section on its wall surface outside the first connecting hole. The adjusting frame has at least two third connecting holes on its wall surface outside the first connecting hole. The third connecting holes are formed on a plane perpendicular to their central axes. The projection of the second connecting hole is located within the projection formed by the second connecting hole on a plane perpendicular to its central axis. The adjustment frame is fixedly connected to the fixed frame by sequentially fitting the second connecting hole and the third connecting hole through the second shaft-type connector. The calibration components are distributed at the end of the fixed frame near the second connecting hole and on the wall of the adjustment frame outside the third connecting hole. The portion of the calibration components distributed on the adjustment frame outside the first adjustment structure consists of a first pointer and a first scale value. The first pointer is integrally formed at the end of the fixed frame near the second connecting hole and its tip extends outward from the fixed frame. The first scale value is set on the wall of the adjustment frame outside the third connecting hole and is distributed in an arc shape.

[0008] As a further improvement of the present invention, the second adjustment structure includes a fourth connecting hole, a fifth connecting hole, a third shaft-type connector, a sixth connecting hole, a seventh connecting hole, and a fourth shaft-type connector. The adjustment frame has several fourth connecting holes arranged linearly along its length. The light source module has fifth connecting holes on both sides. The light source module is movably connected to the adjustment frame by sequentially fitting the third shaft-type connectors into the fourth and fifth connecting holes. The adjustment frame has a sixth connecting hole with an arc-shaped cross-section on the wall surface outside the fourth connecting holes. The light source module has a seventh connecting hole on both sides of the wall surface outside the fifth connecting holes. The light source module is sequentially fitted to the sixth connecting hole by the fourth shaft-type connectors. The adjustment frame is fixedly connected to the connecting hole and the seventh connecting hole. The calibration component is distributed on the part of the adjustment frame located outside the second adjustment structure, including a shim, a second pointer, and a second scale value. The shim is located outside the fourth connecting hole and the sixth connecting hole and is penetrated by the third shaft-type connector and the fourth shaft-type connector. The second pointer is integrally formed on the end of the shim near the sixth connecting hole and its tip extends outward from the shim. The second scale value is set on the wall of the adjustment frame located outside the sixth connecting hole and is distributed in an arc shape. The angle formed by the second scale value and the center point of the fourth connecting hole is angle c, and the angle formed by the sixth connecting hole and the fourth connecting hole is angle d. The angles c and d are the same.

[0009] As a further improvement of the present invention, the adjustment frame is provided with a first groove near the light source module side, and a connecting wire extending into the first groove is provided on one side of the light source module. A plurality of first connecting posts are provided inside the first groove near the connecting wire side. An eighth connecting hole is provided in the middle of the first connecting post. A first connecting plate is provided in the space outside the first connecting post of the first groove, which can be fixedly connected to the adjustment frame by fitting with a fastener into the eighth connecting hole. A through connector communicating with the first groove is provided at the long end of one adjustment frame near the connecting wire side.

[0010] As a further improvement of the present invention, the light source module includes a housing with several heat dissipation fins on the back, a light-emitting element, and a PC lens. A mating groove is provided on the front of the housing, and a light source circuit board is fixedly connected within the mating groove. Several light-emitting elements are embedded on the surface of the light source circuit board. The PC lens is located outside the light-emitting elements and is fixedly connected to the housing. The PC lens has several first protrusions that bulge away from the light-emitting elements and are hemispherical. The ends of the first protrusions near the light-emitting elements are recessed to form a direct projection surface. The projection of the direct projection surface in the direction of the first protrusions protruding outward from the PC lens is semi-elliptical, and its area decreases as the distance to the light-emitting element increases. The projection of the direct projection surface on a plane perpendicular to the straight line of the direction of the first protrusions protruding outward from the PC lens is an elliptical arc. Below the first protrusions, a second protrusion with a wedge-shaped cross-section and a length protruding outward from the PC lens that decreases progressively from bottom to top is integrally formed. The end face of the second protrusion away from the light-emitting element is an arc-shaped surface, and the end face of the second protrusion near the first protrusion is a plane. The recessed end face of the second protrusion near the light-emitting element forms a first reflection. The projection of the first reflective surface onto the PC lens in the direction of the first protrusion is an elliptical arc. The light-shielding module includes a grid-shaped first reflector and an extension member. The first reflector has several connecting portions protruding away from the light-emitting element. The PC lens has several protruding pillars protruding away from the light-emitting element. Both the connecting portions and the protruding pillars have a ninth connecting hole in their middle. The first reflector is disposed on the outside of the PC lens through the connecting portions that fit outside the protruding pillars, and is secured by fasteners fitting into the ninth connecting holes of both the connecting portions and the protruding pillars. In connection with the PC lens, the first protrusion and the second protrusion are both located within the mesh of the first reflector. The first reflector is integrally formed with a plurality of first reflective blocks protruding away from the light-emitting element on the outside of the second protrusion. The projection of the first reflective block on a plane perpendicular to the length direction of the first reflective block is L-shaped. The front end face and the lower end face of the first reflective block are transitioned by rounded corners. The two sides of the first reflective block extend towards the front end face of the first reflector. The outer wall surface of the first reflective block is the second reflective surface. The extension member is disposed outside the top of the PC lens.

[0011] As a further improvement of the present invention, the extension member is a second reflector, which includes a second reflective block, a positioning block, and a second connecting plate. At least two first reflectors are provided on the outer side of the PC lens. The second reflective block is disposed outside the PC lens above the first reflector. The top of the first reflector has several second grooves. The bottom of the positioning block has a first protrusion that mates with the second groove. The middle of the positioning block has a tenth connecting hole. The positioning block is fixedly connected to the PC lens by a connector that passes through the tenth connecting hole and into the PC lens. The top of the positioning block has a third groove. The structure of the second reflective block is the same as that of the first reflective block. The length of the lower end of the second reflective block is greater than the length of the lower end of the first reflective block. The end of the second reflective block near the PC lens has several paired first through slots. The second reflective block is connected to the positioning block by mates with the positioning block at the outer end of the third groove through the first through slots. The top of the second connecting plate is provided with several pairs of second through slots. The second connecting plate is movably connected to the end of the second reflector near the first through slot by cooperating with the positioning block located at the outer end of the third groove through the second through slots. There is a gap between the two first reflectors. The middle and bottom ends of both sides of the second connecting plate are provided with extension plates. The extension plate in the middle of the second connecting plate is located in the gap and extends outward from the gap. The top sides and the middle sides of the first reflector are recessed to form a curved part. The wall surface of the first reflector located in the curved part is integrally formed with a second protrusion with a wedge-shaped cross-section. The wall surface of the extension plate near the curved part is integrally formed with a third protrusion with a wedge-shaped cross-section. The third protrusion is located in the curved part and its inclined surface fits with the inclined surface of the second protrusion. The wall surface of the second reflector located on the outer side of the top of the second connecting plate and the wall surface of the top of the positioning block located on the outer side of the third groove are provided with at least one eleventh connecting hole for connecting the fixing member.

[0012] As a further improvement of the present invention, the extension member is a third reflector, which is distributed in a semi-enclosed manner on the top outside of the PC lens. The projection of the third reflector on a plane perpendicular to the length direction of the PC lens is wedge-shaped. The inner wall of the third reflector near the PC lens is covered with a reflective layer that can refract light. The inner wall of the third reflector near the reflective layer is provided with several extensions. The extensions are provided with several twelfth connecting holes for connecting the fixing member. The third reflector is fixed on the outer side of the top of the PC lens by sequentially passing through the twelfth connecting hole, the PC lens and the outer shell.

[0013] As a further improvement of the present invention, a transparent light-transmitting plate made of glass is fixedly connected to the outside of the PC lens.

[0014] As a further improvement of the present invention, the portion of the calibration component distributed at the top of the light source module is a laser calibrator. The laser calibrator is fitted with a sleeve, and the bottom end of the sleeve is integrally formed with a clamp-shaped fixing part. A fixing block is fixedly connected to the top of the light source module. A snap-fit ​​hole is provided in the middle of the fixing block. A snap-fit ​​block extending outside the snap-fit ​​hole is snapped into the snap-fit ​​hole. The bottom end of the fixing part abuts against the top surface of the snap-fit ​​block and is fitted with a clamping block on its outer side. The end of the clamping block near the fixing part is clamp-shaped and snaps into the outer wall of the fixing part and the bottom surface of one end of the snap-fit ​​block. At least two through holes are provided on both sides of the fixing part and in the middle of the clamping block. Screws are fitted through the through holes on both sides of the fixing part and in the clamping block, where the central axis is on the same straight line.

[0015] As a further improvement of the present invention, a second connecting post is provided on the wall surface of the light source module away from the light-emitting end, and a safety rope is provided on the outer side of the light source module away from the light-emitting end. The safety rope has several branch segments, and a thirteenth connecting hole is provided in the middle of the second connecting post. The ends of the branch segments are located in the thirteenth connecting hole and are fixedly connected to the light source module. Matching holes are provided on both sides of the light source module, and a respirator is fitted in the matching hole.

[0016] The beneficial effects of this invention are as follows: the lighting angle adjustment of the entire lamp and the local lighting angle adjustment of the lamp can be flexibly utilized according to the needs of the site, so that the stadium lamp can meet the lighting needs of different scenarios. By optimizing the structure of the light-emitting end of the lamp, an asymmetrical optical design is formed on the light-emitting end, so that the light emitted from the light-emitting end is concentrated as much as possible towards the ground, while avoiding upward light spillage. This gives the lamp good anti-glare capability while minimizing light pollution. In addition, the setting of the calibration component improves the adjustment accuracy of the illumination range and makes the angle adjustment operation simpler, improving the flexibility and convenience of lamp use.

[0043] The embodiments of the present invention will now be described in conjunction with the accompanying drawings and related examples: This invention discloses a modular anti-glare stadium light with adjustable illumination angle, such as... Figure 1 and Figure 2 As shown, it includes: The bracket module 1 consists of a fixed frame 11 and an adjusting frame 12. The fixed frame 11 is provided with an adjusting frame 12 at the end that is not fixed to an external object. The adjusting frame 12 is connected to the left and right sides of the fixed frame 11 through a first adjusting structure 2, and its tilt angle relative to the fixed frame 11 is adjusted through the first adjusting structure 2. A light source module 3 is disposed between two adjustment frames 12, and the number of such modules is at least one. The left and right sides of the light source module 3 are connected to the adjustment frame 12 through a second adjustment structure 4, and the tilt angle of the module relative to the adjustment frame 12 is adjusted by the second adjustment structure 4. A light-shielding module 5 is connected to the light-emitting end 31 of the light source module 3 and is distributed at at least two positions in the light source module 3. The light-shielding module 5 reflects the light emitted from the surface of the light-emitting end 31 with an upward component relative to the horizontal plane through a portion distributed at any position in the light source module 3 or through all portions distributed in the light source module 3. The light is emitted in any direction where the surface of the light-shielding module 5 above the light emission point of the light-emitting end 31 forms an angle greater than 0° with the horizontal direction. The calibration component 6 is distributed on the outside of the first adjustment structure 2, the outside of the second adjustment structure 4, and the top of the light source module 3. It provides a visual reference when the first adjustment structure 2 adjusts the tilt angle of the adjustment frame 12 relative to the fixed frame 11, when the second adjustment structure 4 adjusts the tilt angle of the light source module 3 relative to the adjustment frame 12, and when the light source module 3 is illuminated at an absolutely parallel or specific angle.

[0044] It should be noted that: the end of the fixed frame 11 that is not connected to the adjustable frame 12 has several mounting holes for fixing to external objects such as lamp poles, lamp holders, and walls, so that it can be fixed to the external objects with mounting bolts; at least one light source module 3 can be connected to the adjustable frame 12, and the number can be adjusted according to the actual needs of the lighting installation site. The first adjustment structure 2 not only realizes the fixed connection of the adjustable frame 12 to the left and right sides of the fixed frame 11, but also adjusts the tilt angle of the adjustable frame 12 relative to the fixed frame 11 by adjusting the connection state of the first adjustment structure 2, thereby simultaneously adjusting the illumination angle of all light source modules 3 to achieve the illumination angle adjustment of the whole lamp; the second adjustment structure 4 not only realizes the fixed connection of the light source module 3 to the adjustable frame 12, but also adjusts the tilt angle of the light source module 3 relative to the adjustable frame 12 by adjusting the connection state of the second adjustment structure 4, thereby adjusting the illumination angle of a single light source module 3. The illumination angle of the light source module 3 is adjusted to achieve the effect of adjusting the illumination angle of a local position of the lamp. The asymmetrical optical design formed by the light source module 3 and the light shielding module 5 connected to its light-emitting end 31 can reflect the light emitted from the light-emitting end 31 of the lamp with an upward component relative to the horizontal plane. With the surface of the light shielding module 5 located above the light emission point of the light-emitting end 31 forming an angle greater than 0° with the horizontal direction in any emission direction, the light emitted from the light-emitting end 31 of the lamp is concentrated towards the ground, giving the lamp the ability to control the light spillage of zero upward light, so as to achieve the effect of anti-glare. In addition, the calibration component 6 distributed on the first adjustment structure 2, the second adjustment structure 4 and the light source module 3 not only improves the accuracy of the lamp's illumination range, but also makes the operation of adjusting the connection state of the first adjustment structure 2 and the second adjustment structure 4 simpler, and makes the control of the lamp's illumination range more flexible.

[0045] It needs to be further explained that, such as Figure 1 , Figure 3 and Figure 4As shown, the first adjustment structure 2 includes a first connecting hole 21, a first shaft-like connector 22, a second connecting hole 23, a third connecting hole 24, and a second shaft-like connector 25. The fixed frame 11, on both sides of the end not fixed to the external object, and the adjustment frame 12 are both provided with first connecting holes 21. The adjustment frame 12 is movably connected to the fixed frame 11 via the first shaft-like connector 22 through two first connecting holes 21 whose central axes are on the same straight line. The fixed frame 11 has a second connecting hole 23 with an arc-shaped cross-section on the wall surface outside the first connecting hole 21. The adjustment frame 12 has at least two third connecting holes 24 on the wall surface outside the first connecting hole 21. The projection of each third connecting hole 24 onto a plane perpendicular to its central axis is... Within the projection of the second connecting hole 23 onto a plane perpendicular to its central axis, the adjusting frame 12 is sequentially fitted into the second connecting hole 23 and the third connecting hole 24 via the second shaft connector 25 and fixedly connected to the fixing frame 11. The calibration components 6 are distributed at the end of the fixing frame 11 near the second connecting hole 23 and on the wall of the adjusting frame 12 outside the third connecting hole 24. The portion of the calibration components 6 distributed on the adjusting frame 12 outside the first adjusting structure 2 consists of a first pointer 61 and a first scale value 62. The first pointer 61 is integrally formed on the end of the fixing frame 11 near the second connecting hole 23 and its tip extends outward from the fixing frame 11. The first scale value 62 is set on the wall of the adjusting frame 12 outside the third connecting hole 24 and is distributed in an arc shape.

[0046] In this configuration, after the first shaft-type connector 22 is fitted into the first connecting hole 21 with two central axes aligned on the same straight line, the adjusting frame 12 is movably connected to the fixed frame 11. With the first shaft-type connector 22 not locked, the adjusting frame 12 can rotate outside the fixed frame 11 around the central axis of the first shaft-type connector 22 to adjust its tilt angle relative to the fixed frame 11, thereby simultaneously adjusting the illumination angle of all light source modules 3 on the adjusting frame 12, thus achieving overall lamp illumination angle adjustment. During the rotation of the adjusting frame 12, the first... The position of a pointer 61 outside the first scale value 62 changes, so that the pointer 61 points to a certain angle value on the first scale value 62, allowing the operator to know the tilt angle of the adjusting frame 12 relative to the fixed frame 11; after adjusting the tilt angle of the adjusting frame 12 relative to the fixed frame 11, the second shaft connector 25 is sequentially fitted into the second connecting hole 23 and the third connecting hole 24, and the first shaft connector 22 and the second shaft connector 25 are locked, thereby fixing the position of the adjusting frame 12 on the fixed frame 11.

[0047] It needs to be further explained that, such as Figure 2 , Figure 5 and Figure 6As shown, the second adjustment structure 4 includes a fourth connecting hole 41, a fifth connecting hole 42, a third shaft-type connector 43, a sixth connecting hole 44, a seventh connecting hole 45, and a fourth shaft-type connector 46. The adjustment frame 12 has several fourth connecting holes 41 arranged linearly along its length in the middle. The light source module 3 has fifth connecting holes 42 on both sides. The light source module 3 is movably connected to the adjustment frame 12 via the third shaft-type connector 43, which sequentially engages with the fourth connecting holes 41 and the fifth connecting holes 42. The wall surface of the adjustment frame 12 located outside the fourth connecting holes 41 has a sixth connecting hole 44 with an arc-shaped cross-section. The walls on both sides of the light source module 3 located outside the fifth connecting holes 42 have... The light source module 3 is fixedly connected to the adjustment frame 12 via the fourth shaft connector 46 and the sixth and seventh connection holes 44. The calibration component 6 is distributed on the part of the adjustment frame 12 located outside the second adjustment structure 4, including a shim 63, a second pointer 64, and a second scale value 65. The shim 63 is located outside the fourth and sixth connection holes 41 and is penetrated by the third and fourth shaft connectors 43 and 46. The second pointer 64 is integrally formed on the end of the shim 63 near the sixth connection hole 44 and its tip extends outward from the shim 63. The second scale value 65 is set on the wall surface of the adjustment frame 12 located outside the sixth connection hole 44 and is distributed in an arc shape.

[0048] Specifically, the third shaft connector 43 is sequentially fitted into the fourth connecting hole 41 and the fifth connecting hole 42, completing the initial connection between the light source module 3 and the adjustment frame 12. Then, the fourth shaft connector 46 is sequentially fitted into the sixth connecting hole 44 and the seventh connecting hole 45, strengthening the connection between the light source module 3 and the adjustment frame 12. With both the third shaft connector 43 and the fourth shaft connector 46 not locked, the light source module 3 can rotate around the central axis of the third shaft connector 43 outside the adjustment frame 12 to adjust the tilt angle of the light source module 3 relative to the adjustment frame 12, thereby achieving the illumination angle adjustment of a single light source module 3 and realizing the illumination angle adjustment effect of a local position of the lamp. Due to the shape and structure of the sixth connecting hole 44 and the fourth shaft connector 46 penetrating the gasket 63 and connecting to the light source module 3... During the rotation of the light source module 3, the fourth shaft connector 46 moves within the sixth connecting hole 44, and the end of the shim 63 through which the fourth shaft connector 46 passes rotates around the central axis of the third shaft connector 43 under the drive of the fourth shaft connector 46. This causes the end of the shim 63 near the second pointer 64 to move outside the second scale value 65, changing the position of the second pointer 64 outside the second scale value 65. Thus, the second pointer 64 points to a certain angle value on the second scale value 65, allowing the operator to know the tilt angle of the light source module 3 relative to the adjustment frame 12. After adjusting the tilt angle of the light source module 3 relative to the adjustment frame 12, the position of the light source module 3 on the adjustment frame 12 is fixed by locking the third shaft connector 43 and the fourth shaft connector 46.

[0049] It needs to be further explained that, such as Figure 7 and Figure 8 As shown, the adjustment bracket 12 has a first groove 121 near the light source module 3. One side of the light source module 3 has a connecting wire 32 extending into the first groove 121. The first groove 121 near the connecting wire 32 has a plurality of first connecting posts 33. The middle of the first connecting post 33 has an eighth connecting hole 331. The space outside the first connecting post 33 in the first groove 121 has a first connecting plate 34 that can be fixedly connected to the adjustment bracket 12 by fitting with a fastener into the eighth connecting hole 331. The long end of one adjustment bracket 12 near the connecting wire 32 has a wire connector 35 that communicates with the first groove 121.

[0050] The wiring connector 35 allows external power lines (not shown in the figure) to pass into one of the adjustment brackets 12 of the lamp. The first groove 121 in the adjustment bracket 12 provides a position for the wiring 32 of the light source module 3 and the external power lines. The wiring connected to the lamp is hidden in the adjustment bracket 12, making the lamp more aesthetically pleasing and protecting the lamp wiring. In addition, the first connecting plate 34 provides an installation position for the power terminal (not shown in the figure) on the lamp, so that the external power lines and wiring 32 can be connected through the power terminal to provide the power required for the light source module 3 to work, simplify the power connection operation of the light source module 3, and also shield the opening side of the first groove 121 through the first connecting plate 34, thereby further protecting the lamp wiring.

[0051] It needs to be further explained that, such as Figure 1 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13As shown, the light source module 3 includes a housing 36 with several heat dissipation fins on the back, light-emitting elements 37, and a PC lens 38. The front of the housing 36 has a mating groove 361, within which a light source circuit board 39 is fixedly connected. Several light-emitting elements 37 are embedded on the surface of the light source circuit board 39. The PC lens 38 is located outside the light-emitting elements 37 and is fixedly connected to the housing 36. The PC lens 38 has several hemispherical first protrusions 381 that bulge away from the light-emitting elements 37. The ends of the first protrusions 381 near the light-emitting elements 37 are recessed to form a direct-projection surface 3811, which bulges outward from the first protrusions 381 towards the PC lens 38. The projection formed in the direction of light emission is semi-elliptical, and the area decreases as the distance to the light-emitting element 37 increases. The projection of the direct projection surface 3811 on the plane perpendicular to the straight line of the first protrusion 381 protruding outward from the PC lens 38 is an elliptical arc. Below the first protrusion 381, a second protrusion 382 with a wedge-shaped cross-section and a length that continuously decreases from bottom to top as it protrudes outward from the PC lens 38 is integrally formed. The end face of the second protrusion 382 away from the light-emitting element 37 is an arc-shaped curved surface, and the end face of the second protrusion 382 near the first protrusion 381 is a plane. The end face of the second protrusion 382 near the light-emitting element 37 is recessed to form a first reflective surface 3821. The projection of a reflective surface 3821 onto the PC lens 38 in the direction of the first protrusion 381 is an elliptical arc. The light-shielding module 5 includes a grid-shaped first reflector 51 and an extension member. The first reflector 51 has several connecting portions 512 protruding away from the light-emitting element 37. The PC lens 38 has several protruding pillars 383 protruding away from the light-emitting element 37. Both the connecting portions 512 and the protruding pillars 383 have a ninth connecting hole 52 in their middle. The first reflector 51 is disposed on the outside of the PC lens 38 through the connecting portions 512 that fit outside the protruding pillars 383, and a fixing member is fitted into the ninth connecting holes 52 of both the connecting portions 512 and the protruding pillars 383. To achieve connection with the PC lens 38, the first protrusion 381 and the second protrusion 382 are both located within the mesh of the first reflector 51. The first reflector 51 has a plurality of first reflective blocks 511 integrally formed outside the second protrusion 382, ​​protruding away from the light-emitting element 37. The projection of the first reflective block 511 on a plane perpendicular to the length direction of the first reflective block 511 is L-shaped. The front end face and the lower end face of the first reflective block 511 are transitioned by rounded corners. The two sides of the first reflective block 511 extend towards the front end face of the first reflector 511. The outer wall of the first reflective block 511 is the second reflective surface 5111. The extension is disposed outside the top of the PC lens 38.

[0052] When the light-emitting element 37 emits light, the light emitted from the upper part of the light-emitting element 37 illuminates the direct-light surface 3811. After passing through the direct-light surface 3811, the light rays maintain a straight line and pass through the first protrusion 381. When passing through the outer surface of the first protrusion 381, the outer surface of the first protrusion 381 refracts the light rays, thereby refracting the light emitted from the upper part of the light-emitting element 37 onto the first reflective block 511. Then, the second reflective surface 5111 reflects the light rays, and the light rays are emitted horizontally at an angle greater than 0° towards the ground. When the light emitted from the lower part of the light-emitting element 37 illuminates the junction of the first protrusion 381 and the second protrusion 382, ​​the light rays maintain a straight line and pass through the junction of the first protrusion 381 and the second protrusion 382 after passing through the direct-light surface 3811. At the junction of the outer surfaces of the first protrusion 381 and the second protrusion 382, ​​the light rays illuminate the ground in a direction collinear with the incident direction. The light emitted from the lower part of the light-emitting element 37, after passing through the second protrusion 382, ​​refracts the light rays. After the light is incident on the plane near the first protrusion 381, it passes through the second protrusion 382 in a straight line and is refracted after reaching the first reflective surface 3821. After being refracted, the light exits the second protrusion 382 in a straight line with a reflection angle of the same size as the incident angle. After exiting the second protrusion 382, ​​the light is blocked by the inner wall of the first reflective block 511, which is located at a lower position. By reflecting the light above the light-emitting element 37 through the reflective block on the first reflector 51 towards the ground, the lamp can achieve the effect of zero upward light and achieve the best overflow light control effect. The maximum illuminance of the whole lamp can reach 165 lm / w. Moreover, the first light shield can be detachably connected to the PC lens 38 through the cooperation of the connecting part 512 and the protrusion 383 and the cooperation of the fixing part (not shown in the figure) in the ninth connecting hole 52. Thus, according to the requirements of different venues for the overflow light control effect of the lamp, different sizes of first light shields can be selected for use to minimize light pollution during the use of the lamp.

[0053] Specifically, such as Figures 14-17As shown, the extension member is a second reflector 53, which includes a second reflective block 531, a positioning block 532, and a second connecting plate 533. At least two first reflectors 51 are provided on the outer side of the PC lens 38. The second reflective block 531 is positioned above the first reflectors 51 on the outside of the PC lens 38. The top of each first reflector 51 has several second grooves 513. The bottom of the positioning block 532 has a first protrusion 5321 that mates with the second grooves 513. The middle of the positioning block 532 has a tenth connecting hole 5322. The positioning block 532 passes through the tenth connecting hole 532... A connecting piece that penetrates into the PC lens 38 achieves a fixed connection with the PC lens 38. The top of the positioning block 532 is provided with a third groove 5323. The structure of the second reflective block 531 is the same as that of the first reflective block 511. The length of the lower end of the second reflective block 531 is greater than that of the lower end of the first reflective block 511. The end of the second reflective block 531 near the PC lens 38 is provided with several pairs of first through slots 5311. The second reflective block 531 is connected to the positioning block 532 by engaging with the outer end of the positioning block 532 located in the third groove 5323 through the first through slots 5311. The top of the second connecting plate 533 is provided with several pairs of second through slots 5331. The second connecting plate 533 is movably connected to the end of the second reflector 531 near the first through slot 5311 by cooperating with the positioning block 532 located at the outer end of the third groove 5323 through the second through slots 5331. There is a gap between the two first reflectors 51. The middle part and the bottom ends of both sides of the second connecting plate 533 are provided with extension plates 5332. The extension plate 5332 in the middle of the second connecting plate 533 is located in the gap and extends outward from the gap. The top sides and the middle sides of the first reflector 51 are recessed. A curved portion 514 is formed. The wall surface of the first reflector 51 located within the curved portion 514 is integrally formed with a second protrusion 515 having a wedge-shaped cross-section. The wall surface of the extension plate 5332 near the curved portion 514 is integrally formed with a third protrusion 5333 having a wedge-shaped cross-section. The third protrusion 5333 is located within the curved portion 514 and its inclined surface is in contact with the inclined surface of the second protrusion 515. The wall surface of the second reflector 531 located on the outer side of the top of the second connecting plate 533 and the wall surface of the top of the positioning block 532 located on the outer side of the third groove 5323 are both provided with at least one eleventh connecting hole 534 for connecting the fixing member.

[0054] To ensure the luminaire achieves zero upward light effect, a second reflector 53 with a longer second reflective surface 5111 is provided at the top of the PC lens 38. This ensures that all light rays incident on the second reflector 53 from bottom to top are reflected by the second reflective surface 5111 on the bottom outer surface of the second reflector 53. The second reflector 53 is small in size, which reduces the size of the light source module 3 when used in the luminaire, offering high flexibility. When using the second reflector 53, the positioning block 532 is first fixed to the top of the PC lens 38. Then, the second reflector 531 is connected to the positioning block along the direction where the first through groove 5311 and the positioning block 532 are located at the outer end of the third groove 5323. Above 532, and on both sides of the top of the PC lens 38, a second reflector block 531 is provided. Then, a second connecting plate 533 is movably connected above the end of the second reflector block 531 near the first through groove 5311, in the direction where the second through groove 5331 and the positioning block 532 are located at the outer end of the third groove 5323. Finally, a first reflector 51 is connected to the outside of the PC lens 38 above the second reflector 53, in the direction where the connecting part 512 and the protrusion 383 are engaged. At this time, the extension plate 5332 located in the middle of the second connecting plate 533 is located between the two first reflectors 51, and the first protrusion 5321 is engaged in the second groove 513. Simultaneously, the third protrusion 5333 is located at the curved... The third protrusion 5333 presses against the second protrusion 515, and its inclined surface fits against the inclined surface of the second protrusion 515. Furthermore, as the operator pushes the extension plate 5332 located in the middle of the second connecting plate 533 upwards, the third protrusion 5333 will press against the second protrusion 515. Through the relative movement of the inclined surfaces of the third protrusion 5333 and the second protrusion 515, the guiding effect of the protrusion 383 on the connecting portion 512, and the guiding effect of the first protrusion 5321 on the portion of the first reflector 51 located on the side of the second groove 513, the first reflector 51 moves away from the PC lens 38, thereby adjusting the light reflection direction of the first reflector 51 and the second reflector 53, further controlling the first reflector... The position and area effect of the light reflected by the first reflector 51 and the second reflector 53 on the ground; after the adjustment of the light reflection direction of the first reflector 51 and the second reflector 53 is completed, the position of the second reflector 53 is fixed by connecting a fixing member (not shown in the figure) into the eleventh connecting hole 534, and the fixing member is pressed against the wall outside the eleventh connecting hole 534 on the top of the second connecting plate 533, thereby fixing the position of the second reflector 53 and the second connecting plate 533. Then, by engaging a fixing member in the ninth connecting hole 52 (not shown in the figure), the first reflector 51 and the PC lens 38 are fixedly connected to fix the position of the first reflector 51.

[0055] Specifically, such as Figure 18 and Figure 19As shown, the extension member is a third reflector 54, which is semi-enclosed on the top of the PC lens 38. The projection of the third reflector 54 on a plane perpendicular to the length direction of the PC lens 38 is wedge-shaped. The inner wall of the third reflector 54 near the PC lens 38 is covered with a reflective layer 541 that can refract light. The inner wall of the third reflector 54 near the reflective layer 541 is provided with several extensions 542. The extensions 542 are provided with several twelfth connecting holes 5421 for connecting and fixing components. The third reflector 54 is fixed on the top outside of the PC lens 38 by sequentially passing through the twelfth connecting holes 5421, the PC lens 38, and the outer shell 36.

[0056] To ensure the luminaire achieves zero upward light effect, a third reflector 54 with a large-area reflective function is set at the top of the PC lens 38. The semi-enclosed structure of the third reflector 54 and its length advantage in the same direction as the light output direction can reflect all the light rays that are shot towards the third reflector 54 from bottom to top by the reflective layer 541 on the inner surface of the third reflector 54. The third reflector 54 is connected to the top of the PC lens 38 by means of a fastener fitted into the twelfth connecting hole 5421, so that the third reflector 54 can be connected to the luminaire in a detachable manner.

[0057] More specifically, such as Figure 20 As shown, a transparent light-transmitting plate 10 made of glass is fixedly connected to the outside of the PC lens 38.

[0058] The lens used in the light source part of the lamp can be a PC lens 38 alone as the lens structure of the lamp, or a combined lens structure of PC lens 38 and transparent glass light-transmitting plate 10 can be used, which can protect the light-shielding module 5 on the outside of PC lens 38.

[0059] It needs to be further explained that, such as Figures 21-23As shown, the portion of the calibration component 6 distributed at the top of the light source module 3 is a laser calibrator 66. A sleeve 661 is fitted over the laser calibrator 66. A clamp-shaped fixing part 6611 is integrally formed at the bottom end of the sleeve 661. A fixing block 662 is fixedly connected to the top of the light source module 3. A snap-fit ​​hole 6621 is provided in the middle of the fixing block 662. A snap-fit ​​block 67 extending beyond the snap-fit ​​hole 6621 snaps into the snap-fit ​​hole 6621. The fixing part 66... The bottom end of 11 abuts against the top surface of the snap-fit ​​block 67 and is fitted with a clamping block 68 on its outer side. The end of the clamping block 68 near the fixing part 6611 is clamp-shaped and snaps into the outer wall of the fixing part 6611 and the bottom surface of one end of the snap-fit ​​block 67. At least two through holes 69 are provided on both sides of the fixing part 6611 and in the middle of the clamping block 68. Screws 610 are fitted through the through holes 69 on both sides of the fixing part 6611 and in the clamping block 68, where the central axis is on the same straight line.

[0060] By installing a laser calibrator 66 on the top of the light source module 3, the laser line can be used as a visual reference to calibrate the optical path of the lamp during optical path position correction, thereby guiding the physical positioning of the equipment and ensuring that the lamp beam is parallel. When installing the laser calibrator 66 on the top of the light source module 3, first, the sleeve 661 is fitted over the laser calibrator 66, then the fixing part 6611 abuts against the surface of one end of the snap-fit ​​block 67, and then the clamping block 68 is fitted to the outer side of both the outer wall of the fixing part 6611 and the snap-fit ​​block 67, and the through holes 6 in the clamping block 68 are aligned. With the screws 610 aligned, insert them through the holes 69 on both sides of the fixing part 6611 and the central axis of the clamping block 68, thus connecting the laser calibrator 66 to the snap-fit ​​block 67. Finally, insert the end of the snap-fit ​​block 67 away from the fixing part 6611 into the snap-fit ​​hole 6621 to snap it into the fixing block 662, thus completing the installation of the laser calibrator 66 on the top of the light source module 3. When the laser calibrator 66 needs to be replaced, the laser calibrator 66 can be removed from the top of the light source module 3 by pulling out the snap-fit ​​block 67 from the snap-fit ​​hole 6621. The operation is simple.

[0061] It needs to be further explained that, such as Figure 9 , Figure 24 and Figure 25 As shown, a second connecting post 310 is provided on the wall surface of the light source module 3 away from the light-emitting end 31. A safety rope 7 is provided on the outer side of the light source module 3 away from the light-emitting end 31. The safety rope 7 has several branch segments 71. A thirteenth connecting hole 3101 is provided in the middle of the second connecting post 310. The ends of the branch segments 71 are located in the thirteenth connecting hole 3101 and are fixedly connected to the light source module 3. Fitting holes 8 are provided on both sides of the light source module 3. A respirator 9 is fitted in the fitting holes 8.

[0062] Each light source module 3 on the lamp is connected to a safety rope 7. This prevents the light source module 3 from falling from a height due to human error during installation or maintenance, and also prevents it from falling from a height without human intervention during use. In addition, the light source module 3 has mating holes 8 on both sides, and the breather 9 installed in the mating holes 8 can achieve pressure balance inside and outside the lamp. In this process, it cleverly solves a series of problems such as waterproofing, heat dissipation, and condensation prevention. The use of both the safety rope 7 and the breather 9 enhances the safety of the lamp during use.

[0063] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
