Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, specifically a floodlight. Background Technology

[0002] Lighting plays a crucial role in sports facilities, as it determines the experience for athletes and fans. To ensure that athletes and spectators can track fast-moving athletes and clearly see their detailed movements, sports lighting systems must provide high levels of illumination. Stadium lighting needs to offer clear, uniform light without shadows or blind spots, especially in large stadiums where spectators are far from the field. Furthermore, the lighting equipment must be glare-free to easily record on-field movements and ensure that viewers at home can clearly see the game unfolding on the field.

[0003] However, existing lighting fixtures share a common problem: regardless of the height of the light pole, the area illuminated by a single fixture will exhibit uneven lighting, shadows, or blind spots—a phenomenon commonly known as "dark spots under the light." Assuming the fixtures themselves are of good quality, clean, and the wiring is functioning correctly, reducing shadows in a given area typically involves using multiple fixtures simultaneously, optimizing their arrangement, and adjusting their angles. This requires optimizing the arrangement and angles of multiple fixtures for a single area, necessitating a larger investment in lighting fixtures and subsequent power supply for a sports stadium. Furthermore, glare from lighting equipment is also a prevalent issue.

[0004] To address the aforementioned issues, reduce the number of light fixtures used, eliminate the need for simultaneous use of multiple fixtures, optimize their arrangement and angle adjustments to save costs, a floodlight was developed and designed. This floodlight provides uniform light intensity and enhanced brightness in its projection area while avoiding glare. Summary of the Invention

[0005] The purpose of this utility model is to provide a floodlight that solves the problems mentioned in the background art. The floodlight provides uniform light intensity and enhanced light brightness in the projection area, while avoiding glare.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows.

[0007] A floodlight includes two oppositely arranged side panels 1, a front cover 2, and a power supply box 7. A reflector 3 is provided on the bottom surface of the front cover 2, and the front ends of the two side panels 1 are connected through the front cover 2. The floodlight also includes an LED assembly A4 and several LED assemblies B6, and the rear ends of the two side panels 1 are connected through the LED assembly A4. Several LED assemblies B6 are arranged between the two side panels 1 along the length of the side panels.

[0008] LED component A4 has a heat sink A41 on its backlight surface, and an LED light panel A42 and a lens A44 are arranged sequentially on the inner side of the heat sink A41A; LED component B6 has a heat sink B61 on its backlight surface, and an LED light panel B62 and a lens B63 are arranged sequentially on the inner side of the heat sink B61; the light-emitting surface of LED light panel B6 faces downward, and the light-emitting surface of LED light panel A42 faces forward and downward; the included angle between the two light panels, LED light panel A42 and LED light panel B62, is in the range of 95-130 degrees.

[0009] The power supply box contains circuit components that power LED component A4 and LED component B6.

[0010] Through the above scheme, the combined structure of reflector 3, two side plates 1 and LED light panel A42 plays a role in constraining and reflecting the light emitted by LED light panel B62, so that it no longer shines directly into people's eyes, avoiding glare, and concentrating the light on the area that needs to be illuminated, thus preventing spillover and reducing light pollution.

[0011] The combined structure of reflector 3, two side plates 1 and LED light panel B62 constrains and reflects the light emitted by LED light panel A42, preventing it from shining directly into people's eyes and avoiding glare. It concentrates the light on the area that needs to be illuminated, thus preventing light spill and reducing light pollution.

[0012] The combined use of LED components A4 and B6, along with the constraints and reflections of the reflector 3 and the two side plates 1, and the mutual constraints and reflections of LED components A4 and B6, result in a large overlap (up to 90%) of the light projection areas of the two light panels A42 and B62. The light rays in this overlapping area intersect each other and complement each other's illumination angles, resulting in uniform brightness and enhanced light intensity in the overlapping light projection areas.

[0013] The angle between LED light panels A42 and B62 ranges from 95 to 130 degrees. This angle is adjusted based on the actual building area, light pole height, the size of the area requiring illumination, and the distance from the light pole. This angle setting also facilitates natural convection cooling of LED components A4 and B6 in different directions through their respective heat sinks.

[0014] In one embodiment, the heat sink A41 includes a base plate A and multiple heat sinks A; the multiple heat sinks A are arranged side by side on the back of the base plate A; an LED light panel A42, a waterproof rubber ring A43, a lens A44 and a grille 45 are sequentially arranged on the inner plane of the base plate A;

[0015] The heat sink B61 includes a base plate B and multiple heat sinks B; the multiple heat sinks B are arranged side by side on the back of the base plate B; the inner surface of the base plate B has a groove, on which LED light panel B62, lens B63, waterproof rubber ring B64, tempered glass panel 65 and glass pressure block 66 are installed in sequence.

[0016] In one embodiment, a plurality of hemispherical protrusions B631 are provided on the outer side of the lens B63, and the protrusions B631 are arranged one-to-one with the LED beads on the LED light panel B62. An axial groove B632 is provided at the center of the bottom surface of the protrusions B631 on the inner side of the lens B63, and the LED beads on the LED light panel B62 are arranged in the axial groove B632.

[0017] In one embodiment, a plurality of hemispherical protrusions A441 are provided on the inner side of the lens A44. The protrusions A441 are arranged one-to-one with the LED beads on the LED light panel A42. An axial groove A442 is provided at the top center of the protrusions A441, and the LED beads on the LED light panel A42 are arranged in the axial groove A442.

[0018] In one embodiment, a grille 45 covers a lens A44. The grille 45 contains a row of equally spaced grid strips, each strip corresponding to the gap between adjacent rows of protrusions 441 on the lens A44. The grille 45 can constrain the light emitted from the LED light panel A42, thus preventing diffuse reflection.

[0019] In one embodiment, the floodlight has one LED component A4 and one LED component B6.

[0020] In one embodiment, the floodlight has one LED component A4 and two LED components B6 arranged side by side, wherein the light-emitting surfaces of the two LED light panels B62 are on the same plane and both face downwards.

[0021] In one embodiment, the floodlight includes two oppositely arranged side plates 1, a front cover 2, an upper cover 9, a rear cover 10, and a power supply box 7. The bottom surface of the front cover 2 is provided with a reflector 3.

The rear cover 10 has several ventilation holes. The upper cover 9 covers the upper edge of the two side plates 1. Several groups of L-shaped LED components with reflectors are arranged sequentially along the length of the side plates between the two side plates 1 and below the upper cover 9. The L-shaped LED components with reflectors include a reflector 31 and an LED component A4. The rear edge of the reflector 31 is connected to the upper edge of the LED component A4 in the same group. The first group of reflectors 31 is arranged side by side behind the reflector 3. The lower edge of the previous group of LED components A4 in two adjacent groups of LED components with reflectors is connected to the front edge of the next group of reflectors 31. All reflectors 31 are relatively parallel.

[0022] In one embodiment, the floodlight includes two oppositely arranged side plates 1, a front cover 2, a rear cover, a power supply box 7, and a bracket. The bottom surfaces of the front cover 2 and the rear cover are provided with reflectors. The front ends of the two side plates 1 are connected through the front cover 2, and the rear ends of the two side plates 1 are connected through the rear cover. Several LED components B6 are arranged side by side between the two side plates along the length direction of the side plates.

[0023] In one embodiment, a bracket 5 is also provided on the two side plates. The bracket 5 is U-shaped, and the two open ends 51 of the bracket 5 are set on the two side plates 1 by two infinitely rotating components 8.

[0024] In one embodiment, the infinitely rotating assembly 8 includes a rotating base 81, a wheel cover 82, and a wheel pressure block 83;

[0025] An opening end groove 822 is made from the inner edge of the upper side of the rotating wheel cover 82 to fit into the opening end 51 of the bracket;

[0026] The top cover 82 of the rotating wheel, the open end 51 of the bracket, and the center of the rotating base 81 are all provided with a central hole, and are installed on the side plate 1 in sequence by bolts; several holes are provided around the central hole on the rotating base 81, and are fixedly installed on the side plate 1 by bolts.

[0027] The center holes of the upper cover 82 of the rotating wheel and the open end 51 of the bracket are not provided with internal threads, while the center hole of the rotating base 81 is provided with internal threads. The upper cover 82 of the rotating wheel and the rotating base 81 are rotatably connected.

[0028] At the corresponding positions on the inner and outer sides of the upper cover 82 of the rotating wheel, and on the outer side of the groove 822 at the opening end, a semi-circular positioning groove 823 and a semi-circular sliding groove 824 are sequentially opened from the inner side to the outer side of the upper cover 8 of the rotating wheel. The width of the positioning groove 823 is narrower than the width of the sliding groove 824.

[0029] A positioning hole A814 with a diameter smaller than the width of the positioning groove 823 is made on the rotating base 81 at a position corresponding to the positioning groove 823;

[0030] The rotating pressure block 83 is arc-shaped, with its inner and outer sides respectively conforming to the inner and outer sides of the sliding groove 824 and sliding within the sliding groove 824. The length of the rotating pressure block 83 is less than that of the sliding groove 824. A positioning hole B831 is provided in the middle of the rotating pressure block 83. The positioning hole A814 and the positioning hole B831 are connected by bolts, so that the position of the rotating pressure block 83 is relatively fixed relative to the rotating base 81 and the rotating pressure block 83 does not slide in the sliding groove 824. At the same time, the rotating upper cover 82 is relatively fixed relative to the rotating base 81.

[0033] The above method fixes the lamps to the lamp post using brackets, and uses a stepless rotation assembly.

[0034] The lamp body can rotate 180 degrees with the center hole at the open end of the bracket as the axis.

[0035] The overall design of the floodlight in this application has a relatively small windward area, so it is less susceptible to wind force. For floodlights used on outdoor high poles, the probability of wind damage is relatively lower compared to other lighting fixtures. Attached Figure Description

[0060] 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.

[0061] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0062] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0063] like Figure 1-3As shown, a floodlight includes two oppositely arranged side panels 1, a front cover 2, and a power supply box 7. A reflector 3 is provided on the bottom surface of the front cover 2, and the front ends of the two side panels 1 are connected through the front cover 2. The floodlight also includes LED assembly A4 and LED assembly B6, and the rear ends of the two side panels 1 are connected through LED assembly A4. An LED assembly B6 is arranged between the two side panels 1 along the length of the side panels.

[0064] LED component A4 has a heat sink A41 on its backlight surface, and an LED light panel A42 and a lens A44 are arranged sequentially on the inner side of the heat sink A41. LED component B6 has a heat sink B61 on its backlight surface, and an LED light panel B62 and a lens B63 are arranged sequentially on the inner side of the heat sink B61. The light-emitting surface of LED light panel B62 faces downward, and the light-emitting surface of LED light panel A42 faces forward and downward. The included angle between the two light panels, LED light panel A42 and LED light panel B62, is in the range of 95-130 degrees.

[0065] The power supply box contains circuit components that power LED component A4 and LED component B6.

[0066] Through the above scheme, the combined structure of reflector 3, two side plates 1 and LED light panel A42 plays a role in constraining and reflecting the light emitted by LED light panel B62, so that it no longer shines directly into people's eyes, avoiding glare, and concentrating the light on the area that needs to be illuminated, thus preventing spillover and reducing light pollution.

[0067] The combined structure of reflector 3, two side plates 1 and LED light panel B62 constrains and reflects the light emitted by LED light panel A42, preventing it from shining directly into people's eyes and avoiding glare. It concentrates the light on the area that needs to be illuminated, thus preventing light spill and reducing light pollution.

[0068] The combined use of LED light panels A42 and B62, along with the constraining and reflecting effects of the reflector 3 and the two side plates 1, and the mutual constraining and reflecting effects of LED components A4 and B6, results in a significant overlap (up to 90%) between the two projection areas of LED light panels A42 and B62. The light rays from this overlapping area intersect and complement each other's illumination angles, leading to uniform brightness and enhanced light intensity in the overlapping projection areas. Figure 9As shown, the light projection area of ​​LED light panel A42 is between A1 and A2, and the light projection area of ​​LED light panel B62 is between B1 and B2. The light projection areas between B1 and A2 are overlapping areas, with uniform light intensity and enhanced light brightness. The light projection area between A1 and B2 is the total area of ​​the light projection areas of LED light panels A and B. Due to the combined structure of the entire lighting fixture, which plays a role in preventing light spill and reducing light pollution, the area of ​​the light projection area between B1 and A2 is close to the area of ​​the light projection area between A1 and B2.

[0069] like Figure 4-6 As shown, the angle between LED light board A42 and LED light board B62 ranges from 95 to 130 degrees. The angle should be adjusted based on the actual building area, light pole height, the size of the area to be illuminated, and the distance from the light pole. For areas requiring maximum and most uniform illumination, and where the area is relatively large, a slightly larger angle is needed, with a maximum of 130 degrees. For areas requiring maximum and most uniform illumination, and where the area is relatively small, a slightly smaller angle is needed, with a minimum of 95 degrees. A suitable angle is 105 degrees.

[0070] The aforementioned angle setting also facilitates natural convection heat dissipation of LED component A4 and LED component B6 in different directions through the heat sink.

[0071] One embodiment, such as Figure 7 As shown, the radiator A41 includes a base plate A and multiple heat sinks A; the multiple heat sinks A are arranged side by side on the back of the base plate A; an LED light panel A42, a waterproof rubber ring A43, a lens A44 and a grille 45 are arranged sequentially on the inner plane of the base plate A;

The protrusions B631 are arranged one-to-one with the LED beads on the LED light panel B62. An axial groove B632 is provided at the center of the bottom surface of the protrusions B631 on the inner side of the lens B63. The LED beads on the LED light panel B62 are arranged in the axial groove B632.

[0074] One embodiment, such as Figure 11 As shown, multiple hemispherical protrusions A441 are provided on the inner side of lens A44.

An axial groove A442 is provided at the top center of the protrusion A441, and the LED beads on LED light board A42 are arranged in the axial groove A442.

[0075] One embodiment, such as Figure 7 As shown, the grille 45 covers the lens A44. The grille 45 contains a row of equally spaced grid strips, each corresponding to the gap between any two adjacent rows of protrusions 441 on the lens A44. The grille 45 can constrain the light emitted by the LED light panel A42, preventing diffuse reflection.

[0076] One embodiment, such as Figure 10 As shown, the floodlight has one LED component A4 and two LED components B6 arranged side by side, wherein the emitting surfaces of the two LED panels B62 are on the same plane and both face downwards. Alternatively, the floodlight may have one LED component A4 and three or more LED components B6 arranged side by side, wherein the emitting surfaces of the LED panels B62 are on the same plane and all face downwards.

[0077] One embodiment, such as Figure 14-17 As shown, the floodlight includes two oppositely arranged side plates 1, a front cover 2, an upper cover 9, a rear cover 10, and a power supply box 7. The bottom surface of the front cover 2 is provided with a reflector 3. The front ends of the two side plates 1 are connected through the front cover 2, and the rear ends of the two side plates 1 are connected through the rear cover 10. The rear cover 10 has several ventilation holes. The upper cover 9 covers the upper edge of the two side plates 1. Below the upper cover 9, two sets of L-shaped LED components with reflectors are arranged sequentially along the length of the two side plates 1. The L-shaped LED components with reflectors include a reflector 31 and an LED component A4. The rear edge of the reflector 31 is connected to the upper edge of the LED component A4 in the same group. The first set of reflectors 31 is arranged side by side behind the reflector 3. The lower edge of the upper set of LED components A4 in two adjacent sets of LED components with reflectors is connected to the front edge of the next set of reflectors 31. All reflectors 31 are relatively parallel. Alternatively, three or more sets of L-shaped LED components with reflectors can be arranged sequentially along the length of the two side panels 1.

[0078] One embodiment, such as Figure 18-19As shown, the floodlight includes two oppositely arranged side panels 1, a front cover 2, a rear cover, a power supply box 7, and a bracket. The bottom surfaces of both the front cover 2 and the rear cover are equipped with reflectors. The front ends of the two side panels 1 are connected via the front cover 2, and the rear ends of the two side panels 1 are connected via the rear cover. Two LED components B6 are arranged side-by-side between the two side panels along their length. Alternatively, three or more LED components B6 may be arranged side-by-side between the two side panels along their length.

[0079] One embodiment, such as Figure 20-23 As shown, the two side plates are also provided with brackets 5. The brackets 5 are U-shaped, and the two open ends 51 of the brackets 5 are set on the two side plates 1 through two infinitely rotating components 8.

[0080] One embodiment, such as Figure 20-22 As shown, the infinitely rotating assembly 8 includes a rotating base 81, a wheel cover 82, and a wheel pressure block 83;

[0081] An opening end groove 822 is made from the inner edge of the upper side of the rotating wheel cover 82 to fit into the opening end 51 of the bracket;

[0082] The top cover 82 of the rotating wheel, the open end 51 of the bracket, and the center of the rotating base 81 are all provided with center holes, and are installed on the side plate 1 in sequence by bolts;

[0083] The center holes of the upper cover 82 of the rotating wheel and the open end 51 of the bracket are not provided with internal threads, while the center hole of the rotating base 81 is provided with internal threads. The upper cover 82 of the rotating wheel and the rotating base 81 are rotatably connected.

[0084] The rotating base 81 has several holes around the central hole, and is fixedly mounted on the side plate 1 by bolts;

[0085] At the corresponding positions on the inner and outer sides of the upper cover 82 of the rotating wheel, on the outer side of the groove 822 at the opening end, a semi-circular positioning groove 823 and a semi-circular sliding groove 824 are sequentially opened from the inner side to the outer side of the upper cover 82 of the rotating wheel. The width of the positioning groove 823 is narrower than the width of the sliding groove 824.

[0086] A positioning hole A814 with a diameter smaller than the width of the positioning groove 823 is made on the rotating base 81 at a position corresponding to the positioning groove 823;

[0087] The rotating pressure block 83 is arc-shaped, with its inner and outer sides respectively conforming to the inner and outer sides of the sliding groove 824 and sliding within the sliding groove 824. The length of the rotating pressure block 83 is less than the length of the sliding groove 824. A positioning hole B831 is provided in the middle of the rotating pressure block 83. The positioning hole A814 and the positioning hole B831 are connected by bolts, which can fix the position of the rotating pressure block 83 relative to the rotating base 81 and prevent the rotating pressure block 83 from sliding in the sliding groove 824. At the same time, the rotating upper cover 82 is fixed relative to the rotating base 81.

[0088] One embodiment, such as Figure 20-22 As shown, a protruding arc-shaped slide rail 821 is provided on the outer side of the positioning groove 823 on the upper cover 82 of the rotating wheel. A groove 811 corresponding to the slide rail 821 is provided on the inner side of the side adjacent to the upper cover 82 of the rotating base 81. The slide rail 821 is embedded in the groove 811. The slide rail 821 and the groove 811 reduce the contact area between the upper cover 82 of the rotating wheel and the rotating base 81, which can reduce the friction when the two rotate relative to each other.

[0089] One embodiment, such as Figure 23 As shown, the inner edge of the groove 822 at the opening end of the upper cover 82 of the rotating wheel is provided with several protrusions 8221, and the outer edge of the opening end 51 of the bracket 5 is provided with several recesses 511 that fit into the protrusions 8221. The fitting design of the protrusions 8221 and the recesses 511 further enhances the stability of the bracket installed on the upper cover of the rotating wheel.

[0090] The lamp is fixed to the lamp post by the bracket. The lamp body can rotate 180 degrees around the center hole of the bracket opening using the stepless rotating assembly. When it is necessary to change the installation angle of the lamp body, unscrew the bolts in positioning holes A and B, rotate the rotating base 81 to the required angle position, and the rotating wheel pressure block 83 will slide in the slide groove 824 to the required angle position. Then, tighten the bolts in positioning holes A and B to fix the lamp body to the required angle.

[0091] The floodlight in this application has a relatively small windward area, thus reducing its susceptibility to wind damage. For outdoor high-mast floodlights, this lowers the probability of wind damage compared to other lighting fixtures. The entire fixture is simply secured with bolts and nuts, but other existing methods can also be used.

[0092] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
