[0034] like Figure 1-Figure 7As shown, the present embodiment provides a floodlight, which includes a carrier frame 1, an illumination module 2 and a support frame 3. A plurality of illumination modules 2 are provided, and the plurality of illumination modules 2 are arranged in sequence along the circumference of the carrier frame 1. The illumination module 2 is detachably connected to the carrier frame 1, and includes a fixing frame 21, a light emitting member 22 and a plurality of dimming members 23. The fixing frame 21 is arranged on the carrier frame 1, and the light emitting member 22 is arranged in the fixing frame 21. The plurality of dimming members 23 are arranged at intervals on the fixing frame 21. A light passage 231 is arranged through the dimming member 23. One end of the light passage 231 is arranged toward the light emitting member 22, and the other end is arranged toward the outside. The dimming member 23 is connected to the fixing frame 21 with an adjustable angle, and can adjust the illumination angle. The support frame 3 is rotatably connected to the carrier frame 1.

[0035] In this embodiment, a plurality of illumination modules 2 are provided, and the plurality of illumination modules 2 are sequentially arranged along the circumference of the support frame 1. The illumination modules 2 are detachably connected to the support frame 1, and the user can adjust the number and position of the illumination modules 2 according to actual needs to adapt to the illumination intensity requirements of different scenes. The illumination module 2 includes a fixing frame 21, a light emitting member 22, and a plurality of dimming members 23. The fixing frame 21 is arranged on the support frame 1, and the light emitting member 22 is arranged in the fixing frame 21, which not only protects the light emitting member 22 from the influence of the external environment, but also ensures the stable output of light. The plurality of dimming members 23 are arranged at intervals on the fixing frame 21, and a light passage 231 is arranged through the dimming member 23. One end of the light passage 231 is arranged toward the light emitting member 22, and the other end is arranged toward the outside, so that the light emitted by the light emitting member 22 can pass through the light passage 231 and be emitted to the outside. The dimming element 23 is connected to the fixing frame 21 in an adjustable angle. By adjusting the angle of the dimming element 23 relative to the fixing frame 21, the lighting angle can be accurately adjusted to meet the lighting requirements in different scenes. The support frame 3 is rotatably connected to the carrier frame 1, so that the carrier frame 1 can rotate, further expanding the adjustment space of the lighting range. Through the above settings, the floodlight of this embodiment can adjust the intensity and irradiation angle of the light, which is convenient for disassembly and maintenance and has a wider adaptability.

[0036] It is understandable that when a larger lighting range or higher brightness is required, the user can increase the number of lighting modules 2 , and when a specific lighting mode is required, it can be achieved by adjusting the layout of the lighting modules 2 .

[0037] Specifically, Figure 1-Figure 3 As shown, in the present embodiment, the support frame 1 includes a support plate and two extending plates, the two extending plates are parallel to each other and spaced apart at opposite ends of the support plate, so that the cross-sectional shape of the support frame 1 is U-shaped, and the two extending plates are rotatably connected to the support frame 3, so that the user can adjust the rotation angle of the support plate relative to the support frame 3, thereby driving the light-emitting component 22 to adjust the lighting direction.

[0038] More specifically, in other embodiments, the carrier 1 includes a carrier block, which is a cubic structure as a whole, so as to provide a stable foundation for the light-emitting element 22, making its operation safer and more stable. It is understandable that the specific structure of the carrier 1 is not limited, as long as it can achieve the above functions.

[0039] Specifically, Figure 1-Figure 4 As shown, the illumination module 2 further includes a power supply 28, which is disposed at one end of the fixing frame 21 facing the supporting frame 1, so that the structure of the entire illumination module 2 is more compact. Moreover, the output end of the power supply 28 is connected to the light-emitting element 22, which reduces the loss of energy during the transmission process. Each illumination module 2 includes a corresponding power supply 28, so that when the user assembles the illumination module 2, the independent control and illumination operation of each illumination module 2 can be ensured, without interference, and the operation is more convenient and reliable.

[0040] Specifically, in this embodiment, the fixing frame 21 includes a bracket, and the bracket is detachably connected to the carrier frame 1 by bolts to facilitate installation and removal. Baffles are respectively provided at both ends of the bracket, and the baffle at one end of the bracket extends into the hole opened in the carrier plate to limit the excessive movement of the bracket, while the baffle at the other end of the bracket is arranged along the extension direction of the extension plate, thereby playing a certain protective role for the corresponding components. In other embodiments, the bracket is detachably connected to the carrier frame 1 by buckles, that is, the specific method of detachably connecting the above components is not limited.

[0041] Specifically, Figure 1-Figure 5 As shown, the illumination module 2 also includes a heat sink 24, which is arranged between the bracket of the fixing frame 21 and the light-emitting element 22, and the light-emitting element 22 is arranged against the heat sink 24, ensuring that the heat generated by the light-emitting element 22 during operation can be quickly and effectively transferred to the heat sink 24, and the heat dissipation is accelerated by the heat sink 24. Such an arrangement not only prolongs the service life of the light-emitting element 22, but also ensures the continuous and stable operation of the floodlight, avoiding performance degradation or damage caused by overheating. Among them, the heat sink 24 is a conventional device in this field, so the technicians in this field are clear about its specific structure and working principle, which will not be repeated here.

[0042] More specifically, if Figure 1-Figure 6 As shown, the illumination module 2 further includes a transparent cover 25, which is disposed on the radiator 24 and forms a receiving space 251 with the radiator 24. The light-emitting element 22 is disposed in the receiving space 251, which can effectively isolate the light-emitting element 22 from the external environment, prevent dust, water vapor and other impurities from corroding the light-emitting element 22, and extend the service life of the light-emitting element 22. The fixing frame 21 further includes a cover plate, which is connected to the radiator 24 through the transparent cover 25, thereby providing an installation basis for the dimming element 23, and at the same time, can also protect the transparent cover 25 to prevent scratches by foreign objects.

[0043] In addition, the transparent cover 25 is usually made of a material with high light transmittance, such as glass or special plastic, which can ensure that light will not be significantly scattered or absorbed when passing through, thereby maintaining the purity and brightness of the light emitted by the light emitting element 22. The light emitting element 22 can be an LED light board or an OLED light board. Those skilled in the art are aware of the specific structure of the light emitting element 22, and no further explanation is given here.

[0044] More specifically, Figure 6 As shown, the illumination module 2 further includes a waterproof ring 26, which is sandwiched between the transparent cover 25 and the radiator 24, effectively preventing water, moisture or other liquids from penetrating into the accommodating space 251 from the gap between the transparent cover 25 and the radiator 24, thereby protecting key components such as the light-emitting element 22 and the radiator 24 from damage in a humid environment. The waterproof ring 26 can be made of silicone or rubber.

[0045] Specifically, Figure 3-Figure 6 As shown, a plurality of connection holes 211 are provided at one end of the fixing frame 21 away from the supporting frame 1, and the plurality of connection holes 211 are arranged in sequence and spaced apart along the circumference of the fixing frame 21. A plurality of dimming elements 23 are correspondingly passed through and connected to the plurality of connection holes 211 one by one, so that the dimming elements 23 can be stably passed through and connected to the fixing frame 21, and the uniformity and effectiveness of the illumination are ensured.

[0046] Specifically, Figure 1-Figure 7 As shown, the illumination module 2 also includes an elastic member 27, which is arranged on the fixing frame 21 and is provided with a movable groove 271. The light passage 231 is arranged along the extension direction of the dimming member 23, and one end of the dimming member 23 facing the light-emitting member 22 abuts against the movable groove 271, so that its own angle can be adjusted. Through the above arrangement, the dimming member 23 can be freely rotated or tilted within a certain range, so as to adjust its angle. The user only needs to gently adjust the dimming member 23 to change the illumination direction, and the operation is simple and quick. In addition, the elastic member 27 provides a certain supporting force and restoring force for the dimming member 23, so that the dimming member 23 can maintain a stable motion trajectory when adjusting the angle, avoiding damage or failure caused by excessive adjustment. It can be understood that the elastic member 27 can be a rubber ring or a silicone ring, and no excessive restrictions are made here.

[0047] It should be noted that, in this embodiment, the dimming element 23 is a cylinder, and a light passage 231 extending along its axial direction is provided inside the cylinder, so that the light emitted by the light-emitting element 22 can be concentrated through the cylinder and the angle can be adjusted. In other embodiments, the dimming element 23 is a cone structure, which can further concentrate the light beam. The specific structure and shape of the dimming element 23 are not further limited here, as long as the above-mentioned functions can be achieved.

[0048] More specifically, if Figure 6 As shown, along the extension direction of the elastic member 27, the diameter of the movable groove 271 first increases and then decreases in the direction away from the dimming member 23. An expanded diameter end 232 is provided at one end of the dimming member 23, and the expanded diameter end 232 abuts against the inner wall of the movable groove 271. This not only improves the ability of the dimming member 23 to maintain a stable state after a fixed angle to avoid light shaking, but also limits the angle adjustment range of the dimming member 23 to a reasonable range, thereby ensuring the normal use of the floodlight and preventing the dimming member 23 from being damaged or the lighting effect from being out of control due to excessive adjustment by the user.

[0049] More specifically, Figure 6 and Figure 7 As shown, the elastic member 27 is provided with a plurality of ribs 272 at intervals along its circumference. The ribs 272 are provided in the movable groove 271 along the extension direction of the elastic member 27 and abut against the outer peripheral wall of the dimming member 23. The contact area and friction force between the dimming member 23 and the elastic member 27 are increased by providing the ribs 272, so that the dimming member 23 is more stable when adjusting the angle and is not easily moved accidentally due to external force or vibration.

[0050] Specifically, Figure 1-Figure 3 As shown, the support frame 3 includes a support plate 31 and two extension plates 32. The support plate 31 can be abutted against the ground, providing a stable foundation for the entire floodlight. The two extension plates 32 are respectively arranged at both ends of the support plate 31, and the carrier frame 1 is rotatably connected between the two extension plates 32. The support plate 31 and the extension plates 32 are arranged at an angle, so that the support frame 3 can provide stable support force in both the horizontal and vertical directions, effectively preventing the lighting module 2 from shaking or tipping over during use.

[0051] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
