Technical Field

[0001] The utility model relates to a lighting device, in particular to a floodlight. Background Art

[0002] The floodlight includes an outer frame for surrounding and protecting the light source and a radiator for dissipating heat from the light source. In order to control production costs and reduce overall weight, the outer frame is usually made of plastic, and the light output plate installed in the outer frame is fixed to the outer frame with a clip. After long-term use, plastic is prone to aging, and the position where the clip is connected to the outer frame is prone to damage, which poses a safety risk of the light output plate falling off. Especially for outdoor floodlights, the plastic outer frame ages faster. Therefore, a floodlight with a more stable connection structure is urgently needed. Utility Model Content

[0003] The utility model aims to provide a floodlight to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve the technical problem is:

[0005] A floodlight comprises: a heat sink having a heat sink disposed therein, and heat dissipation ports respectively disposed on two mutually opposite side surfaces of the heat sink; a surrounding frame connected to the top side of the heat sink, and first connecting ears respectively disposed on the outer sides of the surrounding frame close to the two heat dissipation ports; a light source assembly located in the surrounding frame, and a light emitting plate is disposed at a position of the light source assembly located at the top side of the surrounding frame; a connecting buckle having a pressing portion, a first clamping portion and a second clamping portion, a plurality of the first clamping portions are respectively clamped to a plurality of the first connecting ears, a plurality of the pressing portions are respectively pressed against the top side of the light emitting plate, and a plurality of the second clamping portions are respectively clamped to the heat sink at a position on the top side of the heat dissipation port.

[0006] The technical scheme has at least the following beneficial effects: a heat sink is installed in the heat dissipation shell, and the heat sink is used to increase the heat exchange area with the air, thereby realizing heat dissipation of the light source, a frame is arranged on the top side of the heat dissipation shell to form a cavity, and the light source assembly is installed in the cavity. At this time, the light output plate of the light source assembly is located on the top side of the frame, and multiple connecting buckles are respectively installed in the first connecting ears on both sides of the heat dissipation shell, and the connection between the connecting buckle and the first connecting ear is mainly achieved by the first clamping part on the connecting buckle to achieve relative positioning with the first connecting ear, the light output plate is pressed downward to the top side of the heat dissipation shell by the pressing part on the connecting buckle, and the second clamping part on the connecting buckle is clamped to the position of the heat dissipation shell on the top side of the heat dissipation port, so that the connecting buckle is connected to the surrounding frame and the heat dissipation shell respectively, so as to realize multi-point positioning of the light output plate connection structure, greatly improving the stability of the light output plate when it is pressed down and positioned, and the heat dissipation shell used for heat dissipation is mostly made of metal, which is not easy to age, which is conducive to ensuring the structural firmness during long-term use and has higher safety.

[0007] As a further improvement of the above technical solution, the connecting buckle includes a plate body extending in the up and down directions, the pressing portion is arranged at the top of the plate body, the second clamping portion is arranged at the bottom of the plate body, and a first clamping block is arranged in the middle of the plate body and extends upward and obliquely toward one side of the plate body, the first clamping block is the first clamping portion, and the first connecting ear is surrounded by the outer side of the frame to form a connecting channel, the first clamping block passes downward through the connecting channel, and the top side of the first clamping block abuts against the bottom side of the first connecting ear. The first connecting ear is connected to the outside of the frame, and a connecting channel is formed on the outside of the frame that runs through the frame in the up and down directions. When the connecting buckle and the first connecting ear are opposite to each other, the plate body is inserted downward into the connecting channel. Since the first card block on the plate body extends upward at an angle, when the first card block passes through the connecting channel, the first card block will elastically deform in the direction close to the plate body. When the first card block passes through the connecting channel downward, the first card block will elastically reset in the direction away from the plate body. At this time, the top side of the first card block abuts against the bottom side of the first connecting ear, limiting the upward movement of the plate body, thereby maintaining the downward pressing position of the pressing portion at the top position of the plate body on the light output plate.

[0008] As a further improvement of the above technical solution, the bottom of the plate body is provided with a second card block extending obliquely upward from the other side of the plate body, the second card block is the second clamping portion, the second card block extends into the heat dissipation shell and abuts against the inner top side of the heat dissipation shell. Since the second card block on the plate body also extends obliquely upward, when the plate body is inserted downward into the connecting channel, the second card block first contacts the heat dissipation shell, at which time the second card block undergoes elastic deformation, and when the second card block reaches the heat dissipation port position, the second card block elastically resets and extends into the heat dissipation shell and abuts against the inner top side of the heat dissipation shell, so that the plate body can be limited from moving upward at the heat dissipation shell position, and the pressing portion at the top position of the plate body can be kept pressing down on the light output plate.

[0009] As a further improvement of the above technical solution, the top of the plate body is bent toward the light output plate to form a bent section, and the bent section is the pressing portion. The top of the plate body is directly bent to form the pressing portion, which simplifies the production process and helps improve the overall production efficiency.

[0010] As a further improvement of the above technical solution, the bending section elastically deforms upward and presses against the top side of the light output plate. When the bending section presses the light output plate downward, due to elastic deformation, it can provide downward pre-pressure to the light output plate, so that the light output plate is more firmly pressed into the frame.

[0011] As a further improvement of the above technical solution, the plate body is provided with a reinforcing groove at the bending position of the bending section. The reinforcing groove can improve the structural stability of the bending section during elastic deformation, so that the bending section is not easy to directly undergo plastic deformation during elastic deformation.

[0012] As a further improvement of the above technical solution, the frame is provided with second connecting ears on both sides adjacent to the heat dissipation port, and the second connecting ears are matched with the fixing buckles, and the top of the fixing buckles is pressed against the top side of the light output board. At the positions on both sides of the frame adjacent to the heat dissipation port, the fixing buckles can be relatively fixed to the outside of the frame through the cooperation between the second connecting ears and the fixing buckles, and the top of the fixing buckles is used to press against the top side of the light output board, thereby increasing the pressure points on the light output board and further improving the effect of positioning the light output board.

[0013] As a further improvement of the above technical solution, a step is provided on the inner side of the enclosure, the step extends around the enclosure, and the light output board is located on the top side of the step. When the light output board is installed in the enclosure, the step supports and positions the light output board, which is conducive to the rapid installation of the light output board, and the step provides support for the light output board, thereby improving the stability when the lower pressing part presses the side of the light output board.

[0014] As a further improvement of the above technical solution, a sealing groove is provided on the top side of the step, the sealing groove extends along the length direction of the step, a sealing strip is connected in the sealing groove, and the sealing strip abuts against the top side of the light output board. When the light output board is installed in the enclosure, the light output board abuts against the sealing strip, and the sealing strip is used to fill the assembly gap between the light output board and the step, thereby improving the sealing of the light output board installation.

[0015] As a further improvement of the above technical solution, a connector is provided downwardly on the step, and the bottom end of the connector is connected to the heat dissipation shell. The connector is driven into the step and connected to the heat dissipation shell, so that the surrounding frame and the heat dissipation shell can be further tightened, and the stability of the overall connection structure can be further enhanced.

[0027] Reference Figure 1 , Figure 2 and Figure 3 A floodlight comprises a heat sink 100, a surrounding frame 200, a light source assembly 300 and a connecting buckle 400, wherein a heat sink 110 is arranged inside the heat sink 100. In practical applications, the heat sink 110 can be installed on the inner top side of the heat sink 100, closer to the light source, so as to extract the heat faster, and a plurality of heat sinks 110 can be arranged at intervals in the horizontal direction, and two mutually opposite sides of the heat sink 100 are respectively provided with heat dissipation ports, so as to form a channel for airflow to pass through in the heat sink 100, so as to further improve the heat exchange efficiency of the heat sink 110; the surrounding frame 200 is connected to the top side of the heat sink 100, The outer sides of the frame 200 close to the two heat dissipation ports are respectively provided with first connecting ears 210; the light source assembly 300 is located in the frame 200, and the light source assembly 300 is provided with a light output plate 310 at the top side of the frame 200; the connecting buckle 400 has a pressing portion 410, a first clamping portion 420 and a second clamping portion 430, a plurality of the first clamping portions 420 are respectively clamped to a plurality of the first connecting ears 210, a plurality of the pressing portions 410 are respectively pressed against the top side of the light output plate 310, and a plurality of the second clamping portions 430 are respectively clamped to the heat dissipation shell 100 at the top side of the heat dissipation port.

[0028] As can be seen from the above, the heat sink 110 is installed in the heat dissipation shell 100, and the heat sink 110 is used to increase the heat exchange area with the air, so as to achieve heat dissipation of the light source. The frame 200 is formed with a cavity on the top side of the heat dissipation shell 100, and the light source assembly 300 is installed in the cavity. At this time, the light output plate 310 of the light source assembly 300 is located on the top side of the frame 200, and multiple connecting buckles 400 are respectively installed in the first connecting ears 210 on both sides of the heat dissipation shell 100. The connection between the connecting buckle 400 and the first connecting ear 210 is mainly achieved by the first clamping part 420 on the connecting buckle 400 to achieve relative positioning with the first connecting ear 210. The pressing portion 410 on the connecting buckle 400 presses the light emitting plate 310 downwards to the top side of the heat dissipation shell 100, and the second clamping portion 430 on the connecting buckle 400 is clamped to the position of the heat dissipation shell 100 on the top side of the heat dissipation port, so that the connecting buckle 400 is respectively connected to the surrounding frame 200 and the heat dissipation shell 100, thereby realizing multi-point positioning of the connecting structure of the light emitting plate 310, greatly improving the stability of the light emitting plate 310 when being pressed down to position, and the heat dissipation shell 100 used for heat dissipation during use is mostly made of metal, which is not easy to age, which is conducive to ensuring the structural firmness during long-term use and has higher safety.

[0029] There are many ways to connect the connecting buckle 400 to the first connecting ear 210. For example, the connecting buckle 400 is connected to the surrounding frame 200 by the cooperation between the buckle and the slot. In this embodiment, Figure 4 As shown, the connecting buckle 400 includes a plate body 440 extending in the up-down direction, the pressing portion 410 is arranged at the top of the plate body 440, the second clamping portion 430 is arranged at the bottom of the plate body 440, and a first clamping block is arranged in the middle of the plate body 440, which extends upward and obliquely toward one side of the plate body 440, and the first clamping block is the first clamping portion 420. The first connecting ear 210 is surrounded by the outer side of the frame 200 to form a connecting channel, and the first clamping block passes downward through the connecting channel, and the top side of the first clamping block abuts against the bottom side of the first connecting ear 210. In actual applications, the first clamping block can be a block structure connected and fixed on the plate body 440, or a block structure integrally formed on the plate body 440. For example, a part of the plate body 440 is cut off, one side of the cut part is retained to be connected to the plate body 440, and the cut part is bent to form the first clamping block.

[0030] In the embodiment in which the connecting buckle 400 is connected to the first connecting ear 210, the first connecting ear 210 is connected to the outside of the frame 200, and a connecting channel is formed on the outside of the frame 200 to penetrate in the up-down direction. When the connecting buckle 400 and the first connecting ear 210 are opposite to each other, the plate body 440 is inserted downward into the connecting channel. Since the first card block on the plate body 440 extends upward at an angle, when the first card block passes through the connecting channel, the first card block will elastically deform in the direction close to the plate body 440. When the first card block passes through the connecting channel downward, the first card block will elastically reset in the direction away from the plate body 440. At this time, the top side of the first card block abuts against the bottom side of the first connecting ear 210, limiting the upward movement of the plate body 440, so that the pressing portion 410 at the top position of the plate body 440 can be kept pressed down to position the light output plate 310.

[0031] There are many structural forms for forming the second clamping portion 430 on the plate body 440 to clamp with the heat dissipation shell 100. For example, a protruding structure is directly formed on the plate body 440, and the plate body 100 can be clamped by the protruding structure. In order to facilitate installation, in the present embodiment, a second clamping block extending obliquely upward from the other side of the plate body 440 is provided at the bottom of the plate body 440. The second clamping block is the second clamping portion 430. The second clamping block extends into the heat dissipation shell 100 and abuts against the inner top side of the heat dissipation shell 100. Similarly, the second clamping block can be a block structure connected and fixed on the plate body 440, or a block structure integrally formed on the plate body 440. For example, a part of the plate body 440 is cut off, one side of the cut part is retained to be connected to the plate body 440, and the cut part is bent to form the second clamping block. Since the second card block on the plate body 440 also extends upward at an angle, when the plate body 440 is inserted downward into the connecting channel, the second card block first contacts the heat dissipation shell 100, and the second card block is elastically deformed at this time. When the second card block reaches the heat dissipation port position, the second card block elastically resets and extends into the heat dissipation shell 100, and abuts against the inner top side of the heat dissipation shell 100, so that the plate body 440 can be limited from moving upward at the position of the heat dissipation shell 100, and the pressing portion 410 at the top position of the plate body 440 can be kept pressing down on the light output plate 310.

[0032] Furthermore, the top of the plate body 440 is bent toward the direction of the light output plate 310 to form a bent section, and the bent section is the pressing portion 410. The top of the plate body 440 is directly bent to form the pressing portion 410, which simplifies the production process and helps improve the overall production efficiency. In this way, the bending section, the first clamping block and the second clamping block are formed on the plate body 440, and the production process is simple, which can better control the production cost and is more practical.

[0033] The bent section can be directly attached to the top side of the light output plate 310, and the bent section directly presses down the light output plate 310 to rigidly press the light output plate 310, or the bent section can be directly bonded and fixed to the top side of the light output plate 310. In order to further improve the pressing effect on the light output plate 310, in this embodiment, the bent section elastically deforms upward and presses against the top side of the light output plate 310. When the bent section presses the light output plate 310 downward, due to the elastic deformation, the light output plate 310 can be provided with a downward pre-pressure, so that the light output plate 310 is more firmly pressed into the frame 200.

[0034] Furthermore, the plate body 440 is provided with a reinforcing groove 450 at the bending position of the bending section. The reinforcing groove 450 can improve the structural stability of the bending section during elastic deformation, so that the bending section is not prone to direct plastic deformation during elastic deformation.

[0035] In practical applications, two first connecting ears 210 may be disposed at intervals on one side of the frame 200 , and two first connecting ears 210 may be disposed at intervals on the other side of the frame 200 , so that the light output plate 310 is pressed and fixed at four points.

[0036] In order to further enhance the pressing effect on the light output plate 310, in the present embodiment, the second connecting ears 220 are respectively provided on both sides of the surrounding frame 200 adjacent to the heat dissipation port, and the fixing buckle 500 is matched and connected inside the second connecting ears 220, and the top of the fixing buckle 500 is pressed against the top side of the light output plate 310. At the positions on both sides of the surrounding frame 200 adjacent to the heat dissipation port, the fixing buckle 500 can be relatively fixed to the outside of the surrounding frame 200 through the cooperation between the second connecting ears 220 and the fixing buckle 500, and the top of the fixing buckle 500 is used to press against the top side of the light output plate 310, thereby increasing the downward pressure points on the light output plate 310 and further improving the positioning effect of the light output plate 310.

[0037] The first connecting ear 210 and the second connecting ear 220 can adopt the same structure, and the fixing buckle 500 is mainly used to form a single point fixation outside the surrounding frame 200 to achieve compression of the light output plate 310. The fixing buckle 500 has a similar structure to the connecting buckle 400, and the fixing buckle 500 also includes a plate structure, such as Figure 5 As shown, the top of the plate structure is bent to form a portion that presses the light output plate 310, and a third clamping block inclined upward is formed at the bottom of the plate structure, which is used to pass through the space formed by the second connecting ear 220 and the outer side of the frame 200 and then clamped to the bottom side of the second connecting ear 220, so as to achieve the clamping fixation of the fixing buckle 500 and the second connecting ear 220.

[0038] In actual application, two second connecting ears 220 are also spaced apart on one side of the frame 200 and two are spaced apart on the other side of the frame 200. At this time, the four fixing buckles 500 form four fixing points, which press and position the light output plate 310 in a rectangular shape, further improving the effect of positioning the light output plate 310.

[0039] In the above embodiment, the light emitting board 310 can be directly connected to the top side of the enclosure 200. In order to better position the light emitting board 310 and improve the limiting effect of the light emitting board 310, in this embodiment, a step 230 is provided on the inner side of the enclosure 200. The step 230 extends around the enclosure 200, and the light emitting board 310 is located on the top side of the step 230. When the light emitting board 310 is installed in the enclosure 200, the step 230 supports and positions the light emitting board 310, which is conducive to the rapid installation of the light emitting board 310. The step 230 is used to provide support for the light emitting board 310, thereby improving the stability of the pressing portion 410 when pressing the side of the light emitting board 310.

[0040] Furthermore, a sealing groove is provided on the top side of the step 230, and the sealing groove extends along the length direction of the step 230. A sealing strip is connected in the sealing groove, and the sealing strip abuts against the top side of the light output plate 310. When the light output plate 310 is installed in the enclosure 200, the light output plate 310 abuts against the sealing strip, and the sealing strip is used to fill the assembly gap between the light output plate 310 and the step 230, so that the sealing performance of the light output plate 310 can be improved.

[0041] The light source assembly 300 is mainly used to realize outward light. The light source assembly 300 includes a lamp board, lamp beads and a lampshade. The lamp board is connected to the top side of the heat dissipation shell 100. The lamp beads are connected to the lamp board. There are multiple lamp beads. The lampshade is located on the top side of the lamp board. The lampshade is a cover structure with a large top and a small bottom. The bottom of the lampshade covers multiple lamp beads. In actual applications, in order to support the light output plate 310, a support plate can be provided on the top side of the lampshade. The support plate is horizontally arranged and abuts against the bottom side of the light output plate 310, which can further provide support for the light output plate 310. In addition, the support plate on the top side of the lampshade can abut against the inner side of the step 230, so as to quickly install and position the lampshade.

[0042] In the above embodiment, the frame 200 can be pressed against the heat dissipation shell 100 by pressing the light output plate 310 downward with the connecting buckle 400, and a connecting structure can be installed between the frame 200 and the heat dissipation shell 100 to improve the structural stability of the connection between the two. In this embodiment, the step 230 is provided with a connecting piece downward, and the connecting piece can be a structural piece such as a screw or a bolt, and the bottom end of the connecting piece is connected to the heat dissipation shell 100. The connecting piece is driven into the step 230 and connected to the heat dissipation shell 100, so that the frame 200 and the heat dissipation shell 100 can be further tightened, and the stability of the overall connection structure can be further enhanced. In practical applications, the connecting pieces can be installed at the four corners of the step 230, so that the frame 200 can be stably installed on the heat dissipation shell 100.

[0043] In some embodiments, a bracket can be rotatably connected to the outside of the heat dissipation shell 100, and the bracket can be used to conveniently fix the entire assembly to the structure of the external device, and the direction of the light emitting plate 310 can be flexibly adjusted to change the light emitting angle.

[0044] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
