Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0032] This invention provides a lamp; please refer to [link / reference]. Figures 1 to 8 The present invention provides a lamp fixture comprising a mounting frame 100, a first lamp body 101 mounted on the mounting frame 100, a first side rotating frame 200, a second lamp body 201 mounted on the first side rotating frame 200, a second side rotating frame 300, and a third lamp body 301 mounted on the second side rotating frame 300. The mounting frame 100 includes a first end 111 and a second end 112 disposed opposite to each other. The first side rotating frame 200 is rotatably connected to the first end 111, and the second side rotating frame 300 is rotatably connected to the second end 112.

[0033] In this embodiment, the lamp further includes a drive assembly 400, a movable member 420, a first side transmission frame 430, and a second side transmission frame 440. The first side transmission frame 430 and the second side transmission frame 440 are disposed opposite to each other on both sides of the movable member 420. One end of the first side transmission frame 430 is rotatably connected to the movable member 420, and the other end is rotatably connected to the first side rotating frame 200. One end of the second side transmission frame 440 is rotatably connected to the movable member 420, and the other end is rotatably connected to the second side rotating frame 300. The drive assembly 400 is connected to the movable member 420 and is used to drive the movable member 420 to move.

[0034] Understandably, when the lighting direction of the lamp needs to be changed, the drive assembly 400 drives the movable part 420 to move. The movement of the movable part 420 can drive the first side transmission frame 430 and the second side transmission frame 440 to move respectively. In turn, the movement of the first side transmission frame 430 drives the first side rotating frame 200 to rotate, and the movement of the second side transmission frame 440 drives the second side rotating frame 300 to rotate. Since the second lamp body 201 is mounted on the first side rotating frame 200 and the third lamp body 301 is mounted on the second side rotating frame 300, the lighting direction of the second lamp body 201 and the lighting direction of the third lamp body 301 can be changed by changing the position of the movable part 420 to adapt to the lighting needs of the work scene. The drive assembly 400 has high driving efficiency for the movable part 420, which improves the adjustment efficiency of the lighting direction of the lamp and can improve the efficiency of nighttime construction operations.

[0035] In addition, both the second lamp body 201 and the third lamp body 301 are driven by the same set of drive components 400 and moving parts 420, making the drive structure of the lamp simple and reliable.

[0036] In this embodiment, the rotational connection between the relevant components can be a hinge connection. For example, the first side rotating frame 200 is connected to the first end 111 by a hinge, and the second side rotating frame 300 is connected to the second end 112 by a hinge.

[0037] Furthermore, in this embodiment, the first lamp body 101, the second lamp body 201, and the third lamp body 301 can be selected as floodlights or spotlights, and each lamp body can be selected as a high-power or low-power lighting device.

[0038] In one embodiment, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 When the movable component 420 is in the first position 411, the lighting direction of the second lamp body 201 and the third lamp body 301 are the same as the lighting direction of the first lamp body 101, and the lamp is in a direct illumination state. Further, the drive assembly 400 can drive the movable component 420 from the first position 411 to the second position 412, so that the first side transmission frame 430 drives the first side rotating frame 200 to rotate relative to the first end 111 of the fixed frame 100, so that the second side transmission frame 440 drives the second side rotating frame 300 to rotate relative to the second end 112 of the fixed frame 100, so that the first lamp body 101, the second lamp body 201, and the third lamp body 301 are arranged in a ring, thereby changing the lighting direction of the second lamp body 201 and the third lamp body 301 in the horizontal plane, and the lamp switches from a direct illumination state to a ring illumination state. Please refer to [link to relevant documentation]. Figure 3 , Figure 4 , Figure 7 and Figure 8 When the movable part 420 is in the second position 412, the lamp is in a state of all-around illumination.

[0039] Of course, the drive assembly 400 can also drive the movable part 420 to move from the second position 412 to the first position 411, so that the first side transmission frame 430 drives the first side rotating frame 200 to rotate relative to the first end 111 of the fixed frame 100, so that the second side transmission frame 440 drives the second side rotating frame 300 to rotate relative to the second end 112 of the fixed frame 100, so that the lighting direction of the second lamp body 201 and the lighting direction of the third lamp body 301 are the same as the lighting direction of the first lamp body 101, so as to change the lighting direction of the second lamp body 201 and the third lamp body 301 on the horizontal plane, and the lamp switches from the ambient lighting state to the direct lighting state.

[0040] The position of the moving part 420 is driven by the drive component 400 to switch between direct illumination and ambient illumination modes. The lighting direction of the lamp on the horizontal plane is changed by horizontal rotation, so as to efficiently complete the switching of the lamp's lighting state and adapt to different working environments.

[0041] For example, when the lights are in direct illumination, each light can illuminate the work area at maximum power to improve construction efficiency. When the lights are in ambient illumination, each light can adjust its lighting power appropriately to save energy and provide full-area illumination for designated areas such as squares.

[0042] Furthermore, in this embodiment, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 When the movable component 420 is in the first position 411, the first side rotating frame 200, the fixed rod 110, and the second side rotating frame 300 are arranged in a straight line, so that the lighting direction of the second lamp body 201 and the lighting direction of the third lamp body 301 are the same as the lighting direction of the first lamp body 101. Please refer to [link / reference]. Figure 3 , Figure 4 , Figure 7 and Figure 8 When the movable part 420 is in the second position 412, the first side rotating frame 200, the fixed rod 110 and the second side rotating frame 300 form a triangle, so that the first lamp body 101, the second lamp body 201 and the third lamp body 301 are arranged in a circle, and the three lamp bodies illuminate from the center position of the lamp.

[0043] In one embodiment, the drive assembly 400 includes a drive motor 401 and a lead screw 402. A movable component 420 is sleeved on the lead screw 402 and threadedly connected to it. One end of the lead screw 402 is connected to the output shaft of the drive motor 401, and the other end is rotatably connected to the fixed frame 100, thereby driving the position of the movable component 420 and enabling the second lamp body 201 and the third lamp body 301 to rotate and swing horizontally, thus changing their respective lighting directions. Through the drive assembly 400, the lamps can be quickly switched between direct illumination and ambient illumination.

[0044] Specifically, the forward rotation of the output shaft of the drive motor 401 drives the lead screw 402 to rotate, causing the movable part 420 to move from the first position 411 to the second position 412. Conversely, the reverse rotation of the output shaft of the drive motor 401 drives the lead screw 402 to rotate in the opposite direction, causing the movable part 420 to move from the second position 412 to the first position 411. This displacement drive method using the lead screw 402 provides high precision in controlling the specific travel distance of the movable part 420.

[0045] In this embodiment, a limit switch is provided inside the drive motor 401. After the limit switch is preset with a travel limit, the forward and reverse travel of the drive motor 401 can be limited, so as to control the movable part 420 to work between the first position 411 and the second position 412 according to the preset travel limit. That is, when the drive motor 401 is working in the forward direction, after the drive motor 401 drives the movable part 420 from the first position 411 to the second position 412, the limit switch automatically acts to turn off the drive motor 401. When the drive motor 401 is working in the reverse direction, after the drive motor 401 drives the movable part 420 from the second position 412 to the first position 411, the limit switch automatically acts to turn off the drive motor 401.

[0046] Of course, in other embodiments, the drive component 400 may also employ other drive methods such as hydraulic cylinders.

[0047] In one embodiment, please continue reading Figures 1 to 4 The first lamp body 101 is rotatably connected to the fixed frame 100 so that the lighting direction of the first lamp body 101 can be changed relative to the horizontal plane, that is, the first lamp body 101 can be tilted to change the lighting direction of the first lamp body 101. The second lamp body 201 is rotatably connected to the first side rotating frame 200 so that the lighting direction of the second lamp body 201 can be changed relative to the horizontal plane, that is, the second lamp body 201 can be tilted to change the lighting direction of the second lamp body 201. The third lamp body 301 is rotatably connected to the second side rotating frame 300 so that the lighting direction of the third lamp body 301 can be changed relative to the horizontal plane, that is, the third lamp body 301 can be tilted to change the lighting direction of the third lamp body 301.

[0048] Therefore, the second lamp body 201 and the third lamp body 301 can not only change the lighting direction of the lamp on the horizontal plane by rotating horizontally, but also change the lighting angle of the lamp relative to the horizontal plane by the pitching motion formed by the rotation, so as to provide all-round lighting angle transformation of the lamp; it can further improve the lighting angle range of the lamp and make the lighting adaptability higher.

[0049] The position of each lamp facing the ground is adjusted by controlling the pitch and oscillation of the first lamp body 101, the second lamp body 201, and the third lamp body 301; please refer to [link to relevant documentation]. Figure 2 and Figure 4 Adjusting the downward tilt of each lamp will allow it to illuminate the ground closer to the lamp. Please refer to [link / reference needed]. Figure 1 and Figure 3 Adjusting the upward tilt of each lamp body can illuminate the ground at a distance from the lamp.

[0050] In one embodiment, the lamp further includes a driving device 500, wherein the first lamp body 101, the second lamp body 201 and the third lamp body 301 are all connected to the driving device 500 in a transmission manner, so that the driving device 500 can drive the first lamp body 101, the second lamp body 201 and the third lamp body 301 to rotate, thereby changing the lighting direction of the first lamp body 101, the lighting direction of the second lamp body 201 and the lighting direction of the third lamp body 301.

[0051] The drive device 500 automatically drives the first lamp body 101, the second lamp body 201 and the third lamp body 301 to rotate, which has high driving efficiency and can quickly complete the adjustment of the lighting angle of the first lamp body 101, the second lamp body 201 and the third lamp body 301 relative to the horizontal plane.

[0052] Furthermore, in this embodiment, please continue to refer to... Figures 1 to 4 The drive device 500 includes a first drive mechanism 510, a second drive mechanism 520, and a third drive mechanism 530. One end of the first drive mechanism 510 is movably connected to the fixed frame 100, and the other end is movably connected to the first lamp body 101. One end of the second drive mechanism 520 is movably connected to the first side rotating frame 200, and the other end is movably connected to the second lamp body 201. One end of the third drive mechanism 530 is movably connected to the second side rotating frame 300, and the other end is movably connected to the third lamp body 301. Each of the first lamp body 101, the second lamp body 201, and the third lamp body 301 is equipped with a separate drive mechanism, which allows for more flexible control of the pitch drive angle of each lamp body, enabling different illumination angles relative to the horizontal plane for each lamp body to adapt to the specified working environment.

[0053] For example, the lighting direction of the first lamp body 101 can be controlled to be set at a 45-degree angle relative to the horizontal plane, the lighting direction of the second lamp body 201 can be controlled to be set at a 50-degree angle relative to the horizontal plane, and the lighting direction of the third lamp body 301 can be controlled to be set at a 55-degree angle relative to the horizontal plane. By controlling the different angles of each lamp body, a preset lighting trajectory can be formed.

[0054] Specifically, the first drive mechanism 510, the second drive mechanism 520, and the third drive mechanism 530 are all electric push rods. The extension and retraction of each electric push rod can drive the first lamp body 101, the second lamp body 201, and the third lamp body 301 to rotate respectively, thereby realizing the pitch angle change of the first lamp body 101, the second lamp body 201, and the third lamp body 301. At the same time, the electric push rod has a built-in limit switch, which can control the pitch angle change with high precision.

[0055] Of course, in other embodiments, a driving mechanism can be set to simultaneously drive the pitch movement of the first lamp body 101, the second lamp body 201 and the third lamp body 301. In this case, the angle of the illumination direction of each lamp body relative to the horizontal plane is the same.

[0056] In one embodiment, the fixing frame 100 includes a fixing rod 110 and a connecting rod 120. A first end 111 and a second end 112 are the two ends of the fixing rod 110. A first lamp body 101 is mounted on the fixing rod 110. One end of the connecting rod 120 is connected to the fixing rod 110, and the other end is a free end 121. Further, the first side rotating frame 200 includes a first rotating end 220 and a first abutting end 210. The first rotating end 220 is rotatably connected to the first end 111. The second side rotating frame 300 includes a second rotating end 320 and a second abutting end 310. The second rotating end 320 is rotatably connected to the second end 112. The first side rotating frame 200 can rotate relative to the first end 111, and the first abutting end 210 abuts against the free end 121. The second side rotating frame 300 can rotate relative to the second end 112, and the second abutting end 310 abuts against the free end 121. With the above settings, the positional changes of the first side rotating frame 200 and the second side rotating frame 300 relative to the two ends of the fixed rod 110 can be realized.

[0057] In one embodiment, the first abutting end 210 is provided with a first inclined surface for cooperating with the free end 121, and the second abutting end 310 is provided with a second inclined surface for cooperating with the free end 121. By having the inclined surfaces contact the outer wall surface of the free end 121, the contact area between the first abutting end 210 and the free end 121 can be increased, thereby improving the stability and reliability of the first abutting end 210 and the free end 121. Similarly, the contact area between the second abutting end 310 and the free end 121 can be increased, thereby improving the stability and reliability of the luminaire structure under ambient illumination.

[0058] In one embodiment, the mounting bracket 100 further includes a column 130, one end of which is fixedly connected to the connecting rod 120, and the other end of which is used for external installation connections. The column 130 is used to install the luminaire on designated equipment or work surfaces. The lighting height of the luminaire can be adjusted by adjusting the length of the column 130. For example, the luminaire can be installed on a fixed site or a mobile lighthouse using the column 130, making it widely applicable.

[0059] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
