The floodlight 100 includes a heat dissipation shell 10, an end cover 20 and a reflector 30. Among them, the heat dissipation shell 10 is in the shape of a trough body, and the end cover 20 is arranged on the opposite sides of the heat dissipation shell 10, connected to the heat dissipation shell 10, so as to cover the two ends of the heat dissipation shell 10 in the shape of a trough body, and then form an assembly cavity 110 with the heat dissipation shell 10, the end cover 20 is provided with a first positioning portion 21, and the reflector 30 is arranged in the assembly cavity 110, and the reflector 30 is provided with a second positioning portion 31 that is positioned and matched with the first positioning portion 21.

In the embodiment of the present invention, end covers 20 are provided on opposite sides of the heat dissipation housing 10, and a first positioning portion 21 is provided on the surface of the end cover 20 facing the assembly cavity 110, and a second positioning portion 31 is provided on the reflector 30.

When the cover plate 40 of the floodlight 100 is covered on the assembly cavity 110, the cover plate 40 will abut against the reflector 30, thereby limiting the movement of the reflector 30 in the emission direction of the emitted light, and then fixing the reflector 30 in the assembly cavity 110, thereby improving the disassembly and assembly efficiency of the reflector 30.

Please refer to Figures 5 and 6, Figure 5 is a schematic diagram of the three-dimensional structure of the heat dissipation housing in Figure 1, and Figure 6 is a schematic diagram of the planar structure of the heat dissipation housing in Figure 5. The heat dissipation housing 10 includes a main body plate 12 and side frames 14, and the side frames 14 are connected to the opposite sides of the main body plate 12 to form a trough-shaped heat dissipation housing 10.

The main body plate 12 includes a first main body plate 121, a second main body plate 122, a third main body plate 123, a fourth main body plate 124 and a fifth main body plate 125 which are bent and connected in sequence. The first main body plate 121, the second main body plate 122 and the third main body plate 123 form a power supply assembly groove 112 for assembling a power supply assembly 50 (shown in FIG. 2 ), and the fourth main body plate 124 and the fifth main body plate 125 form a light source assembly assembly groove 114 for assembling a light source assembly 60 (shown in FIG. 2 ).

Specifically, in this embodiment, as shown in FIG. 6 , the second main body plate 122 and the fourth main body plate 124 are arranged in parallel and spaced apart along the first direction (X direction), and are arranged side by side along the second direction (Y direction). The first direction is perpendicular to the second direction. The first main body plate 121 and the fifth main body plate 125 are connected to the two side frames 14, respectively. By arranging the second main body plate 122 and the fourth main body plate 124 to be parallel to each other, the height of the heat dissipation housing 10 in the first direction (X direction) can be reduced to reduce the volume of the floodlight 100.

In this embodiment, the first main plate 121 and the third main plate 123 are obliquely arranged on opposite sides of the second main plate 122 to form a trapezoidal power assembly slot 112 with the second main plate 122. Since the opening of the trapezoidal power assembly slot 112 is relatively large, it is convenient to install the power assembly 50.

Of course, in other embodiments, the first main plate 121 and the third main plate 123 may also be vertically connected to the second main plate 122 to reduce the length of the heat dissipation housing 10 in the second direction (Y direction), thereby reducing the volume of the floodlight 100.

Optionally, as shown in FIG. 2 and FIG. 7 , FIG. 7 is a schematic diagram of the three-dimensional structure of the heat dissipation housing in FIG. 5 at another viewing angle. A through hole 16 is also provided on the heat dissipation housing 10, and the through hole 16 is used to assemble components such as a waterproof wiring head 162 or an air pressure valve 164. For example, in the present embodiment, two through holes 16 are provided on the first main body plate 121, one of the through holes 16 is used to install the waterproof wiring head 162, and the other through hole 16 is used to install the air pressure valve 164. The power cord is connected to the power supply assembly 50 via the waterproof wiring head 162. The air pressure valve 164 is used to adjust the atmospheric pressure in the assembly cavity 110 to prevent the atmospheric pressure in the assembly cavity 110 from being unbalanced with the external atmospheric pressure due to the heat generated by the light source assembly 60, thereby damaging the floodlight 100.

Furthermore, as shown in FIG. 4 , the depth of the power supply assembly groove 112 is greater than the depth of the light source assembly groove 114 , so that the light source assembly 60 installed in the light source assembly groove 114 is closer to the cover plate 40 , thereby avoiding blocking the direction of the emitted light of the light source assembly 60 .

Optionally, as shown in Fig. 6 and Fig. 7, a plurality of heat dissipation fins 17 are provided on the surface of the fourth main body plate 124 and the fifth main body plate 125 on the side away from the light source assembly 60, and the plurality of heat dissipation fins 17 are parallel to each other to form spaced heat dissipation channels. By providing a plurality of heat dissipation fins 17 on the surface of the light source assembly groove 114, on the one hand, the contact area between the heat dissipation housing 10 and the air can be increased, and on the other hand, the flow speed of the air in the heat dissipation channel can be accelerated, thereby accelerating the heat dissipation and further extending the service life of the light source assembly 60.

In this embodiment, as shown in FIG6 and FIG7, the heat dissipation fins 17 are disposed on both the fourth main body plate 124 and the fifth main body plate 125. Of course, in other embodiments, the heat dissipation fins 17 may also be disposed only on the fourth main body plate 124 or the fifth main body plate 125. The present invention does not specifically limit the location and number of the heat dissipation fins 17, and they can be flexibly disposed as needed.

Optionally, the cross section of the heat dissipation fin 17 is in a straight strip shape, an L shape, or a T shape.

Specifically, the heat sink fins 17 can be straight, L-shaped, T-shaped, or partially straight, L-shaped, or T-shaped. Of course, the cross-section of the heat sink fins 17 can also be triangular or arc-shaped, etc., which is not specifically limited in the present invention.

In this embodiment, the cross section of the heat sink fin 17 on the fourth main body plate 124 is L-shaped, and the cross section of the heat sink fin 17 on the fifth main body plate 125 is straight. By setting the heat sink fin 17 on the fourth main body plate 124 to be L-shaped, not only can the strength of the heat sink fin 17 be enhanced to prevent the heat sink fin 17 from being deformed by force when it touches the ground, but also the end of the heat sink fin 17 can be prevented from cutting or scratching the object in contact with it, and the heat sink area of the heat sink fin 17 can be increased to accelerate heat dissipation.

In this embodiment, the ends of the heat dissipation fins 17 disposed on the fourth main body plate 124 are flush with the surface of the second main body plate 122 on the side away from the power supply assembly slot 112 .

Specifically, as shown in FIG6 , in this embodiment, the second main body plate 122 and the fourth main body plate 124 are arranged in parallel and spaced apart, and the height of the heat dissipation fins 17 arranged on the fourth main body plate 124 is equal to the distance between the second main body plate 122 and the fourth main body plate 124, so that the end of the heat dissipation fins 17 away from the fourth main body plate 124 is located on the same plane as the surface of the second main body plate 122. In this way, when the back of the floodlight 100 is placed on the ground, that is, when the side of the heat dissipation housing 10 away from the cover plate 40 is placed on the ground, the second main body plate 122 and the heat dissipation fins 17 are used together to support the floodlight 100, which makes the various parts of the floodlight 100 evenly stressed and has better grounding stability.

Further, as shown in FIG5 , the main body plate 12 is provided with an assembly hole 125 for fixing and installing other components such as the light source assembly 60 and the power supply assembly 50. According to different assembly forms, the assembly hole 125 can be a through hole and/or a blind hole. The thickness of the main body plate 12 at the position where the assembly hole 125 is provided is greater than or equal to the thickness at the position where the assembly hole 125 is not provided, so as to improve the rigidity of the heat dissipation housing 10 and prevent the heat dissipation housing 10 from breaking at the position where the assembly hole 125 is provided.

Specifically, a plurality of assembly holes 125 are provided on the second main body plate 122 for fixing the power supply assembly 50 on the heat dissipation housing 10 in cooperation with screws. A plurality of assembly holes 125 are provided on the fourth main body plate 124 for fixing the light source assembly 60 on the heat dissipation housing 10 in cooperation with screws.

Optionally, the assembly hole 125 is disposed at a position of the main body plate 12 where no heat dissipation fins 17 are disposed, that is, the assembly hole 125 is disposed at a gap between the heat dissipation fins 17 to prevent the assembly hole 125 from affecting the rigidity of the heat dissipation housing 10 .

Furthermore, the heat dissipation housing 10 also includes an enclosure plate 18 , one side of the enclosure plate 18 is connected to the main plate 12 , and the other side of the enclosure plate 18 is connected to the side frame 14 , so as to enclose the side frame 14 and the main plate 12 to form a through groove 182 .

Specifically, as shown in Fig. 5 and Fig. 6, the two opposite sides of the enclosure plate 18 are respectively connected to the surfaces of the main plate 12 and the side frame 14 away from the assembly cavity 110, so as to form a through groove 182 on the side away from the assembly cavity 110. On the one hand, the inner surface and the outer surface of the through groove 182 are in contact with the air, which can increase the heat dissipation area; on the other hand, it can also form convection of the air outside the heat dissipation housing 10, thereby increasing the air flow speed and further accelerating the heat dissipation efficiency; on the other hand, it can also enhance the strength of the side frame 14, making it easier to assemble components such as the bracket 70 (shown in Fig. 2) on the heat dissipation housing 10.

Optionally, screw assembly grooves 184 are provided at both ends of the enclosing plate 18, and the screw assembly grooves 184 include a first screw assembly groove 185 and/or a second screw assembly groove 186. The first screw assembly groove 185 is used to receive screws to be screwed in to assemble the end cover 20, and the second screw assembly groove 186 is used to receive screws to be screwed in to assemble the bracket 70.

Specifically, in this embodiment, as shown in FIGS. 1 , 5 and 6 , a first screw assembly groove 185 and a second screw assembly groove 186 are formed on the inner wall of the through groove 182. The first screw assembly groove 185 is formed at the connection between the enclosing plate 18 and the side frame 14 to facilitate the assembly of the end cover 20. The second screw assembly groove 186 is formed on the enclosing plate 18 to facilitate the assembly of the bracket 70.

Among them, in this embodiment, the aperture of the second screw assembly slot 186 is larger than the aperture of the first screw assembly slot 185, so that the connection between the heat dissipation housing 10 and the bracket 70 is more stable. Of course, in other embodiments, the size of the screw assembly slot 184 can also be reasonably set according to the size and weight of the components installed on the heat dissipation housing 10, and the embodiment of the present invention does not make specific limitations.

In another embodiment, a first screw assembly slot 185 or a second screw assembly slot 186 may be provided respectively according to the assembly requirements of the end cover 20 and the bracket 70. Of course, if the heat dissipation housing 10 needs to assemble more components, more screw assembly slots 184 may be provided on the heat dissipation housing 10, which is not specifically limited in the embodiment of the present invention.

Optionally, the screw assembly groove 184 is formed in a cylindrical shape by a plate extending from the enclosing plate 18. The length of the screw assembly groove 184 may be equal to the length of the through groove 182, that is, a screw assembly groove 184 is formed on the through groove 182 to pass through the length direction of the through groove 182. The screw assembly groove 184 may also be set to a length that matches the length of the screw used for assembly, so as to cooperate with the screw to connect the heat dissipation housing 10 with other components.

As shown in Fig. 4, Fig. 5 and Fig. 6, in this embodiment, the side frame 14 includes a first plate 141, a second plate 142 and a third plate 143 which are bent and connected in sequence, and the first plate 141 is connected to the main plate 12 to support the cover plate 40. The first plate 141 is recessed downward on the surface facing the cover plate 40 to form a first glue sealing groove 144, and the third plate 143 is spaced apart from the first plate 141 through the second plate 142. The first plate 141, the second plate 142 and the third plate 143 form a first glue overflow groove 145 on the side of the first glue sealing groove 144.

In the embodiment of the present invention, a first overflow glue groove 145 is formed on the side of the first glue sealing groove 144. When the cover plate 40 is covered on the first plate 141, excess glue overflowing from the first glue sealing groove 144 will enter the first overflow glue groove 145 and be blocked by the third plate 143, so that the surface of the cover plate 40 will not be exposed. This not only makes the appearance of the floodlight 100 more beautiful, but also avoids the need to set up a separate workstation to clean the overflowed glue, thereby reducing the production complexity of the floodlight 100 and speeding up production efficiency.

Specifically, the side frames 14 are arranged on opposite sides of the main body plate 12 along the second direction (Y direction), the first plate 141 on one side frame 14 is connected to the first main body plate 121 on the heat dissipation housing 10, and the first plate 141 on the other side frame 14 is connected to the fifth main body plate 125 on the heat dissipation housing 10. The first main body plates 121 on the two first side blocks are parallel to each other and located on the same plane, so as to facilitate the installation of the cover plate 40.

Among them, in this embodiment, as shown in Figures 4 and 6, the first sealing groove 144 is opened on the side where the first plate 141 is connected to the main plate 12. When the cover plate 40 is covered on the first plate 141, the first sealing groove 144 can accommodate more glue to enhance the bonding strength between the first plate 141 and the cover plate 40.

Further, as shown in Figures 3 and 8, Figure 8 is a schematic diagram of the three-dimensional structure of the end cover in Figure 2. The end cover 20 includes a connecting plate 22, a first lap plate 24, and a second lap plate 26. The connecting plate 22 is connected to the heat dissipation housing 10, the first lap plate 24 is used to carry the cover plate 40, and the second lap plate 26 is buckled on the surface of the heat dissipation housing 10 facing the assembly cavity 110.

Specifically, as shown in Fig. 3 and Fig. 8, the two connecting plates 22 in the two end covers 20 are respectively arranged on the other opposite sides of the heat dissipation housing 10 where the side frame 14 is arranged, and are used to cover the two sides of the trough-shaped heat dissipation housing 10 to form the assembly cavity 110. The first lap plate 24 and the second lap plate 26 are arranged on the surface of the connecting plate 22 facing the inside of the assembly cavity 110, the first lap plate 24 and the side frame 14 work together to carry the cover plate 40, and the second lap plate 26 is used to connect with the main plate 12.

Optionally, as shown in Fig. 8, a plurality of reinforcing ribs 28 are provided between the first lap plate 24 and the second lap plate 26 to enhance the strength of the end cover 20. Specifically, in the present embodiment, a portion of the reinforcing ribs 28 are provided in a direction perpendicular to the first lap plate 24 and the second lap plate 26, and another portion of the reinforcing ribs 28 are provided in a direction parallel to the first lap plate 24 and the second lap plate 26 to form a grid-like reinforcing rib structure to prevent the end cover 20 from being deformed after being subjected to external force.

As shown in FIG. 8 , a second sealing groove 242 is formed on the surface of the first lap plate 24 facing the cover plate 40 , which is concave downward. The second sealing groove 242 is used to receive glue to seal and bond the cover plate 40 .

Specifically, the second sealing groove 242 is opened on the side of the first lap plate 24 close to the assembly cavity 110 . When the cover plate 40 is covered on the first lap plate 24 , the second sealing groove 242 can accommodate more glue to enhance the bonding strength between the first lap plate 24 and the cover plate 40 .

Furthermore, a second glue overflow groove 224 is formed on the surface of the connecting plate 22 adjacent to the first lap plate 24. Specifically, as shown in FIG8 , a second glue overflow groove 224 is provided on the surface of the connecting plate 22 adjacent to the surface of the first lap plate 24 on which the second glue sealing groove 242 is formed. By forming the second glue overflow groove 224 on the side of the second glue sealing groove 242, when the cover plate 40 is covered on the first lap plate 24, excess glue overflowing from the second glue sealing groove 242 will enter the second glue overflow groove 224, so that the surface of the cover plate 40 will not be exposed, which not only makes the appearance of the floodlight 100 more beautiful, but also avoids the need to set up a separate workstation to clean the overflowed glue, thereby reducing the production complexity of the floodlight 100 and speeding up production efficiency.

Among them, in this embodiment, the second lap plate 26 is buckled on the surface of the heat dissipation shell 10 facing the assembly cavity 110 to increase the contact area at the connection between the end cover 20 and the heat dissipation shell 10, which is convenient for sealing the gap between the end cover 20 and the heat dissipation shell 10 and preventing external impurities from entering the assembly cavity 110 through the gap between the second lap plate 26 and the heat dissipation shell 10.

Further, as shown in FIG9 , FIG9 is a schematic diagram of the three-dimensional structure of the end cover in FIG8 at another viewing angle. A third sealing groove 262 is formed on the surface where the second lap plate 26 contacts the heat dissipation housing 10, and the third sealing groove 262 is used to receive glue to seal and bond the heat dissipation housing 10. By forming the third sealing groove 262 on the surface where the second lap plate 26 contacts the heat dissipation housing 10, the gap between the second lap plate 26 and the heat dissipation housing 10 can be sealed.

Optionally, as shown in Fig. 8, a connecting portion 264 is provided on the second lap plate 26, and an assembly hole 125 is provided at a position of the heat dissipation housing 10 corresponding to the connecting portion 264, and the connecting portion 264 is fixedly connected to the assembly hole 125 by a screw. By respectively providing the connecting portion 264 and the assembly hole 125 on the second lap plate 26 and the heat dissipation housing 10, the connection stability between the end cover 20 and the heat dissipation housing 10 can be enhanced.

Specifically, a plurality of connection portions 264 are spaced apart along the length direction of the second lap plate 26 , and the surface of the connection portion 264 for contacting the heat dissipation housing 10 is flush with the surface of the second lap plate 26 for contacting the heat dissipation housing 10 to enhance the connection stability between the connection portion 264 and the heat dissipation housing 10 .

In this embodiment, as shown in FIG. 8 , the first positioning portion 21 is connected to the first lap plate 24 and the second lap plate 26 , and protrudes from the surface of the first lap plate 24 and the second lap plate 26 facing the assembly cavity 110 , so as to be positioned and matched with the second positioning portion 31 .

8, part of the first positioning portion 21 is sandwiched in the gap between the first lap plate 24 and the second lap plate 26, and another part of the first positioning portion 21 protrudes from the first lap plate 24 and the second lap plate 26. By sandwiching part of the first positioning portion 21 between the first lap plate 24 and the second lap plate 26, the strength of the end cover 20 can be further enhanced.

In this embodiment, as shown in FIG. 2 and FIG. 8 , the first positioning portion 21 includes two parallel and spaced baffles 212 to increase the volume of the first positioning portion 21 and reduce the material of the first positioning portion 21. The second positioning portion 31 is a notch formed on the reflector 30. By increasing the volume of the first positioning portion 21, the positioning stability of the first positioning portion 21 and the second positioning portion 31 can be higher and the positioning effect can be better.

In this embodiment, as shown in Figures 9 and 10, Figure 10 is a partial enlarged schematic diagram of the structure in Figure 3. The length of the first lap plate 24 is less than the length of the connecting plate 22, the end of the first lap plate 24 is spaced apart from the end of the connecting plate 22, and the length of the second overflow glue groove 224 is greater than the length of the second sealing glue groove 242.

After the end cover 20 is assembled with the heat dissipation housing 10, the first glue sealing groove 144 and the first glue overflow groove 145 are connected with the second glue overflow groove 224. The first lap plate 24 and the first plate 141 are spaced apart, and the second glue sealing groove 242 and the second glue overflow groove 224 can be connected with the third glue sealing groove 262 through the gap between the first lap plate 24 and the first plate 141. Thus, the glue overflowing from the first glue sealing groove 144 and the first glue overflow groove 145 can be connected with the third glue sealing groove 262 through the second glue overflow groove 224.

During the assembly process, firstly, glue is applied in the third glue sealing groove 262 to seal the end cover 20 and the heat dissipation housing 10 to form the assembly cavity 110. Subsequently, glue is applied in the first glue sealing groove 144 and the second glue sealing groove 242 to seal and fix the cover plate 40. If there is too much glue in the third glue sealing groove 262, the overflowed glue will flow into the second glue sealing groove 242. If there is more glue in the first glue sealing groove 144 and the second glue sealing groove 242, part of the excess glue will flow into the first overflow glue groove 145 and the second overflow glue groove 224, and part of it will flow into the third glue sealing groove 262 to strengthen the connection between the second lap plate 26 and the heat dissipation housing 10. Therefore, by providing the first glue sealing groove 144, the second glue sealing groove 242, the third glue sealing groove 262, the first glue overflow groove 145 and the second glue overflow groove 224 which are interconnected, not only can the excess glue be prevented from exposing the cover plate 40 and the heat dissipation shell 10, but also the amount of glue can be saved, so that the connection between the end cover 20 and the heat dissipation shell 10 is more stable and the sealing effect is better.

Further, as shown in Fig. 2 and Fig. 4, the floodlight 100 further includes a power supply assembly 50 and a light source assembly 60. The power supply assembly 50 is assembled in the power supply assembly groove 112, and the light source assembly 60 is assembled in the light source assembly assembly groove 114. In the embodiment of the present invention, the power supply assembly 50 is arranged inside the assembly cavity 110, which can reduce the damage of the external environment to the power supply assembly 50, thereby protecting the power supply assembly 50 and extending the service life of the power supply assembly 50.

Different from the prior art, the present invention provides a floodlight 100 on one hand, by arranging end covers 20 on opposite sides of the heat dissipation housing 10, and arranging a first positioning portion 21 on the surface of the end cover 20 facing the assembly cavity 110, and arranging a second positioning portion 31 on the reflector 30. When the reflector 30 is placed in the assembly cavity 110, the second positioning portion 31 is positioned and matched with the first positioning portion 21, thereby limiting the movement of the reflector 30 in two directions perpendicular to the emission direction of the emitted light. When the cover plate 40 of the floodlight 100 is covered on the assembly cavity 110, the cover plate 40 will abut against the reflector 30, thereby limiting the movement of the reflector 30 in the emission direction of the emitted light, and then fixing the reflector 30 in the assembly cavity 110, thereby improving the disassembly and assembly efficiency of the reflector 30. On the other hand, the present invention further provides a heat dissipation housing 10, by forming a first overflow glue groove 145 on the side of the first glue sealing groove 144, when the cover plate 40 is covered on the first plate 141, excess glue overflowing from the first glue sealing groove 144 will enter the first overflow glue groove 145 and be blocked by the third plate 143, so that the surface of the cover plate 40 will not be exposed. This not only makes the appearance of the floodlight 100 more beautiful, but also avoids the need to set up a separate workstation to clean the overflowed glue, thereby reducing the production complexity of the floodlight 100 and speeding up production efficiency.

The above description is only an implementation mode of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
