Description

Technical Field

[0001] The utility model relates to the field of floodlights, and more specifically, to a modular floodlight. Background Art

[0002] A floodlight is a lighting fixture with high brightness and strong focusing properties. It usually uses high-intensity light sources, such as LEDs, metal halide lamps, etc., which can focus light on a specific area to achieve long-distance lighting. Floodlights have a wide range of applications and can be used for architectural lighting, landscape lighting, stadiums, billboard lighting, etc. Its features include waterproof, dustproof, and corrosion-resistant, and it can adapt to various harsh outdoor environments. The beam angle of the floodlight can be adjusted to meet different lighting needs. At the same time, it also has the advantages of high efficiency, energy saving, and long life, providing people with a bright and safe lighting environment at night.

[0003] At present, the light source module of a floodlight is usually a whole, equipped with only one driving power supply. This means that when the circuit inside the light source module is damaged, due to its integrity, the damaged part cannot be repaired separately, and only the entire light source module can be repaired, which will undoubtedly have a great impact on the normal use of the floodlight. For example, in some places that require continuous lighting, the failure of the floodlight may cause safety hazards or affect work efficiency. Moreover, an oversized light source module can easily cause energy waste when working.

[0004] Therefore, in order to solve the above technical problems, the present application proposes a modular floodlight. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a modular floodlight.

[0006] To achieve the above object, the utility model provides the following technical solution: a modular floodlight, comprising a mounting frame and a plurality of light source modules, the back of the mounting frame being fixedly connected to a central support rod, the surface of the central support rod being embedded with a plurality of insertion slots arranged in a vertical array;

[0007] The light source module includes a light source panel and a driving power source located at the back of the light source panel, and the driving power source can be inserted into the insertion slot for limiting;

[0008] Pressing components are installed on both sides of the installation frame to fix the light source module in the installation frame.

[0009] Preferably, the clamping assembly is clamped by a concave-convex fit, which has a better fixing effect than contact clamping, thereby preventing loosening of the assembly.

[0010] Preferably, grooves are provided at positions close to the surface on both sides of the light source module. A plurality of through grooves A arranged vertically in an array are provided on both sides of the mounting frame. The pressing assembly includes connecting groove seats fixed on both sides of the mounting frame and communicating with the through grooves A. A moving plate is slidably connected inside the connecting groove seats. A convex block that can be inserted into the groove is fixedly connected to the surface of the moving plate. A threaded member for pressing the moving plate towards the mounting frame is installed on the connecting groove seats.

[0011] Preferably, the threaded member is a screw rod threadedly connected to the side end of the connecting groove seat.

[0012] Preferably, a rotating plate is fixedly connected to the head of the screw rod. The end of the screw rod is rotatably connected to a pressing plate through a bearing. Limiting plates are fixedly connected to both sides of the surface of the pressing plate. Through grooves B for the limiting plates to pass through and linearly limit them are provided on the surface of the mounting frame, which can effectively reduce the friction of contact and prevent damage to the moving plate.

[0013] Preferably, a mounting bracket is detachably connected to the back of the mounting frame by bolts, and in case of damage to the mounting bracket and the mounting frame, single replacement can also be carried out.

[0014] Preferably, guide rails are fixedly connected to both sides inside the connecting groove seats. Both sides of the moving plate are slidably connected to the guide rails through sliders to maintain the linear movement of the moving plate.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] 1. The present utility model divides the light source module into multiple parts. When in use, the driving power supplies on the appropriate number of light source modules are inserted into the insertion groove seats for positioning, and are placed from the middle to the upper and lower sides. The lighting effect is the best at the middle position. Then, the light source module is pressed and fixed through the pressing assembly, and the assembly of the floodlight can be completed. The light source panel is driven by the driving power supply for lighting. Such a modular assembly design enables the repair of a single damaged light source module by detaching it alone without affecting the normal use of the floodlight. At the same time, the installation quantity of the lighting modules can be selected according to needs to avoid energy waste, thereby solving the problems in the background technology that when the circuit inside the light source module is damaged, due to its integrity, the damaged part cannot be repaired alone, and only the entire light source module can be repaired, affecting the normal use of the floodlight, and that when the light source module is too large during operation, it is easy to cause energy waste.

[0017] 2. The light source module of the present utility model adopts the method of first positioning and then clamping, which can help the user quickly find the installation position of the light source module, thus making it more convenient for the user to carry out the assembly operation of the floodlight.

[0018] 3. In this utility model, the pressing component is pressed in a concave-convex matching manner. Compared with the contact pressing, its fixing effect is better, thus avoiding loosening during assembly.

[0019] 4. When the screw is rotated clockwise in this utility model, the screw will drive the pressing plate to move towards the installation frame, thereby squeezing the moving plate. The pressing plate drives the movement of the limiting plate, and the limiting plate slides along the through groove B, thus maintaining the linear movement of the pressing plate relative to the connecting groove seat. In this way, by squeezing and moving the moving plate with the pressing plate, compared with the rotational contact of the screw, the contact friction can be effectively reduced, and damage to the moving plate can be avoided.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] As Figures 1-4 shown, the present utility model provides a modular floodlight, including an installation frame 1 and a plurality of light source modules 4. A central support rod 2 is fixedly connected to the back of the installation frame 1, and a plurality of insertion groove seats 3 arranged in a vertical array are fixedly embedded on the surface of the central support rod 2;

[0027] The light source module 4 includes a light source panel 401 and a driving power source 402 located at the back of the light source panel 401. The driving power source 402 can be inserted into the insertion slot 3 for positioning.

[0028] Pressing components 5 are installed on both sides of the installation frame 1 to fix the light source module 4 in the installation frame 1 .

[0029] The utility model divides the light source module 4 into multiple ones. When in use, the driving power supplies 402 on the appropriate number of light source modules 4 are inserted into the insertion slot 3 for limiting, and placed from the middle to the upper and lower sides. The lighting effect is best in the middle part. Then, the light source module 4 is pressed and fixed by the clamping component 5 to complete the assembly of the floodlight. The driving power supply 402 drives the light source panel 401 for lighting. Conversely, the light source module 4 is fixed by the contact clamping component 5, and a single light source module 4 can be removed for disassembly or maintenance. With this modular assembly (dividing the light source module 4 into multiple small modules for assembly) design, even if a single light source module 4 is damaged, it can be disassembled and repaired separately without affecting the normal use of the floodlight. At the same time, the installation quantity of the lighting modules can be selected as needed to avoid energy waste. The method of limiting the light source module 4 first and then clamping it can help the user quickly find the installation position of the light source module 4, thereby making it more convenient for the user to perform the floodlight assembly operation.

[0030] At the same time, the back of the mounting frame 1 is detachably connected to the mounting bracket 8 by bolts, so that when the mounting bracket 8 and the mounting frame 1 are damaged, they can be replaced alone, thereby reducing the use cost.

[0031] Moreover, the clamping component 5 is clamped in a concave-convex matching manner, and compared with the contact clamping, its fixing effect is better, thereby avoiding loosening of the assembly. The following is the specific structure of the concave-convex matching method of clamping: grooves 6 are provided on both sides of the light source module 4 near the surface, and multiple through grooves A7 arranged in a vertical array are provided on both sides of the mounting frame 1. The clamping component 5 includes a connecting groove seat 501 fixed on both sides of the mounting frame 1 and communicated with the through groove A7, a movable plate 502 is slidably connected inside the connecting groove seat 501, and a protrusion 503 that can be inserted into the groove 6 is fixedly connected to the surface of the movable plate 502, and a threaded component for squeezing the movable plate 502 toward the mounting frame 1 is installed on the connecting groove seat 501, and the threaded component is a screw 504 threadedly connected to the side end of the connecting groove seat 501.

[0032] During use, rotate the screw 504 clockwise so that the screw 504 moves along the connecting groove base 501 towards the mounting frame 1. The screws 504 on both sides press against the moving plates 502 on both sides and move towards the middle. The moving plates 502 drive the movement of the bumps 503, causing the bumps 503 to pass through the through slot A7 and then insert into the groove 6 of the lighting module (after the driving power supply 402 of the lighting module is inserted into the insertion slot base 3, the through slots on it are exactly aligned with the corresponding through slots and the bumps 503), thereby clamping and fixing the lighting module. At this time, the moving plate 502 is in close contact with the surface of the mounting frame 1. On the contrary, rotate the screw 504 counterclockwise so that it no longer presses against the moving plate 502, and the moving plate 502 can be pushed in the opposite direction (the surface of the connecting groove base 501 is open, facilitating the user to push the moving plate 502), thereby pulling out the bump 503 from the groove 6 and the through slot A7 and releasing the fixation of the light source module 4.

[0033] Furthermore, on both sides inside the connecting groove base 501, there are fixed guide rails 509. Both sides of the moving plate 502 are slidably connected to the guide rails 509 through sliders 510. In this way, when the moving plate 502 moves back and forth, the moving plate 502 drives the movement of the sliders 510, and the sliders 510 move along the guide rails 509 to maintain the linear movement of the moving plate 502 and prevent the moving plate 502 from tilting, which may affect the normal insertion operation of the bump 503. The head of the screw 504 is fixedly connected with a rotating plate 505. The end of the screw 504 is rotatably connected with a pressing plate 506 through a bearing. On both sides of the surface of the pressing plate 506, there are fixed limit plates 507. On the surface of the mounting frame 1, there is a through slot B508 for the limit plates 507 to pass through for linear limiting. In this way, the screw 504 can be rotated through the rotating plate 505. When the screw 504 is rotated clockwise, the screw 504 drives the pressing plate 506 to move towards the mounting frame 1, thereby squeezing the moving plate 502. The pressing plate 506 drives the movement of the limit plates 507, and the limit plates 507 slide along the through slot B508. It should be noted that the cross-sections of the through slot B508 and the limit plates 507 are the same, and the limit plates 507 can only move linearly along the through slot B508, thereby maintaining the linear movement of the pressing plate 506 relative to the connecting groove base 501 (due to the rotational connection between the screw 504 and the pressing plate 506, there is the above limitation, and the screw 504 cannot drive the rotation of the pressing plate 506). In this way, the moving plate 502 is squeezed and moved through the pressing plate 506. Compared with the rotational contact of the screw 504, the contact friction can be effectively reduced, and the moving plate 502 can be prevented from being damaged.

[0034] And there is a heat dissipation port 9 inside the connecting groove base 501, which is convenient for dissipating heat from the driving power supply 402 placed inside. Moreover, the heat dissipation port 9 is relatively large, and the driving power supply 402 can be charged through this heat dissipation port 9.

[0035] The above are only the preferred embodiments of the present utility model, and do not impose any formal restrictions on the present utility model; any ordinary technician in the industry can smoothly implement the present utility model according to the illustrations in the specification and the above description; however, any minor changes, modifications and equivalent variations made by those skilled in the art within the scope of the technical solution of the present utility model by using the technical content disclosed above are all equivalent embodiments of the present utility model; at the same time, any changes, modifications and equivalent variations made to the above embodiments based on the essential technology of the present utility model still fall within the protection scope of the technical solution of the present utility model.
