[0001] This application relates to the field of lighting technology, and more particularly to a hoop lamp. Background Technology

[0002] A clamp light is a lighting fixture that is fixedly installed on a cylindrical object using a clamp structure. It is widely used in road, landscape, or emergency lighting scenarios.

[0003] Light clamps typically employ a clamp structure with a semi-circular corner design. This type of clamp consists of two semi-circular clamp parts connected by bolts or other locking devices, allowing the clamp to fit snugly and securely onto the surface of the cylindrical object being mounted. Clamps usually have a pre-set standard fitting diameter range.

[0004] However, such clamp lights have limitations. When the clamp light is installed on a cylinder with a diameter exceeding the fit range, the clamp may not close completely or may open excessively, causing the clamp light to be unstablely fixed to the cylindrical object. Summary of the Invention

The first limiting member and the second limiting member are respectively connected to the corresponding ends of the two clamping members, and are used to change the size of the closed frame formed by the clamping members by the relative movement of the first limiting member and the second limiting member.

[0007] Optionally, one of the first limiting member and the second limiting member is a rack, and the other is a gear meshing with the rack. The gear can rotate under external force and drive the rack to move, thereby causing the two clamping members to move relative to each other.

[0008] Optionally, the connecting assembly further includes an elastic connector, which is detachably connected between the corresponding ends of the two clamps, and the elastic connector is extendable and retractable along the line connecting the ends of the two clamps to change the distance between the corresponding ends of the two clamps.

[0025] Clamp-on lights are lighting fixtures that are fixed to a cylindrical object using a clamp structure. They are widely used in road, landscape, and emergency lighting scenarios. Clamp-on lights typically employ a semi-circular clamp design with a pre-defined standard diameter range. The clamp usually consists of two semi-circular clamp parts connected by bolts or other locking devices, ensuring a close fit and fixation to the surface of the cylindrical object. However, when such clamp-on lights are installed on a cylinder with a diameter exceeding their suitable range, the two clamp parts may not close completely or may open excessively, resulting in the clamp-on light not being stably fixed to the cylindrical object.

[0026] This application proposes a clamp-on light fixture, which uses a connecting component with an adjustable length to connect directly to the corresponding ends of two clamp pieces. By adjusting the length of the connecting component, that is, by adjusting the distance between the interconnected ends of the two clamp pieces, the circumferential length of the clamp structure formed by the two clamp pieces is changed, thereby enabling the clamp-on light fixture to adapt to mounting columns with different cross-sectional dimensions.

[0027] like Figure 1 As shown, the clamp lamp 100 according to an embodiment of this application may include a load-bearing frame 1, a lamp 2 and a connecting component 3.

[0028] The load-bearing frame 1 serves as the main supporting structure, capable of supporting the weight of the external light fixture 2. The load-bearing frame 1 may include two clamping members 11. The two clamping members 11 can be joined together to form a closed frame. The closed frame can be various shapes such as circular or polygonal. This closed frame is fitted and clamped to the outer periphery of the mounting column, allowing the clamped light fixture 100 to be fixed to the mounting column.

[0029] The luminaire 2 can be mounted on the load-bearing frame 1 to provide a light source. The luminaire 2 can be various lighting components such as light bulbs and LEDs, and can have electrical connection parts such as cables to connect the luminaire 2 to a power source.

[0030] The connecting assembly 3 may include a limiting unit 31. The limiting unit 31 has a first limiting member 311 and a second limiting member 312 respectively connected to the corresponding ends 111 of the two clamping members 11. The connection between the first limiting member 311 and the second limiting member 312 and the ends 111 of the clamping members 11 can be by hinge or welding. The first limiting member 311 and the second limiting member 312 are capable of relative movement. Through the relative movement of the first limiting member 311 and the second limiting member 312, the length of the limiting unit 31 connected between the corresponding ends 111 of the two clamping members 11 can be adjusted, and the distance between the corresponding endpoints of the two clamping members 11 can be changed, thereby changing the size of the closed frame formed by the clamping members 11. Thus, the load-bearing frame 1 assembled from the two clamping members 11 can adapt to mounting columns with different circumferential dimensions by changing its circumferential size.

[0031] In the clamp lamp 100 according to an embodiment of this application, two clamp members 11 of the load-bearing frame 1 are connected by a connecting assembly 3 having a limiting unit 31. The first limiting member 311 and the second limiting member 312 of the limiting unit 31 are respectively connected to the corresponding ends 111 of the two clamp members 11. By causing relative displacement between the first limiting member 311 and the second limiting member 312, the distance between the corresponding ends 111 of the two clamp members 11 connected to the first limiting member 311 and the second limiting member 312 can be changed, thereby changing the circumferential size of the load-bearing frame 1. Thus, the load-bearing frame 1 can be adapted to mounting columns of different sizes, realizing the stable installation of the clamp lamp 100 on mounting columns with different circumferential sizes.

[0032] The technical solutions of this application will be described in detail below with reference to specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0033] In the clamp lamp 100 according to the embodiments of this application, the load-bearing frame 1 can be made of austenitic stainless steel, such as 304 stainless steel or 316L stainless steel. Austenitic stainless steel can provide the load-bearing frame 1 with excellent structural strength, corrosion resistance and long-term service stability. In addition, the surface of the load-bearing frame 1 can be customized according to the application requirements, including but not limited to wire drawing, polishing, sandblasting or spraying a weather-resistant coating of a specific color.

[0034] Since the two clamp members 11 of the load-bearing frame 1 have two pairs of corresponding ends 111, the limiting unit 31 can be two, and each is connected between the two pairs of corresponding ends 111 of the two clamp members 11. Alternatively, in other embodiments, one pair of the two pairs of corresponding ends 111 of the two clamp members 11 can be connected by the limiting unit 31, and the other pair can be connected by bolts or other locking devices.

[0035] The limiting unit 31, which enables the relative movement of the first limiting member 311 and the second limiting member 312, can be a threaded rod, a slider guide, etc. To facilitate control of the relative movement of the first limiting member 311 and the second limiting member 312, optionally, one of the first limiting member 311 and the second limiting member 312 can be a rack, and the other can be a gear meshing with the rack. The gear can be located at the end 111 of one clamp member 11 and rotate around the central axis of the gear in a fixed position. The rack can be fixedly connected to the corresponding end 111 of the other clamp member 100. The gear can be manually driven by a wrench or driven by a motor. Since the gear and rack are meshed, the rotation of the gear will drive the rack to move linearly, thereby causing the two clamp members 11 to move away from or closer to each other. Thus, by changing the size of the closed frame formed by the clamp members 11, the load-bearing frame 1 formed by the two clamp members 11 can adapt to mounting columns with different circumferential dimensions by changing its circumferential size.

[0036] Since the meshing of the gear and rack is continuous, the distance between the corresponding ends 111 of the two clamping parts 11 can be continuously and smoothly adjusted, which facilitates precise control of the distance adjustment.

[0037] Furthermore, when using gears with specific tooth profiles, such as helical gears, the gear rack can possess a certain degree of self-locking performance. Therefore, there is no need to design a complex locking mechanism to ensure that the distance between the corresponding ends 111 of the two clamping members 11 remains constant. In other embodiments, the first limiting member 311 and the second limiting member 312 can also be implemented using a worm gear and a worm.

[0038] A slight relative displacement may occur between the first limiting member 311 and the second limiting member 312 of the limiting unit 31, resulting in a slight change in the distance between the opposite ends 111 of the two clamping members 11 and a change in the circumferential length of the load-bearing frame 1. In this case, the load-bearing frame 1 is prone to detachment from the mounting post. To avoid the above situation, the connecting assembly 3 may optionally include an elastic connector 32. The elastic connector 32 may be a spring or the like. The elastic connector 32 is detachably connected between the corresponding ends 111 of the two clamping members 11, and the elastic connector 32 can extend and retract along the line connecting the ends 111 of the two clamping members 11, thereby changing the distance between the corresponding ends 111 of the two clamping members 11.

[0039] By providing a retractable elastic connector 32 connected between the corresponding ends 111 of the two clamp members 11, when the clamp lamp 100 is installed on the mounting post, the corresponding ends 111 of the two clamp members 11 are continuously acted upon by the elastic connector 32, which ensures that the two corresponding ends 111 are close to each other. Therefore, it is possible to avoid the load-bearing frame 1 from detaching from the mounting post due to relative displacement between the first limiting member 311 and the second limiting member 312 that causes them to move away from each other, or due to an increase in the circumferential length of the load-bearing frame 1.

[0040] Optionally, the length of the elastic connector 32 in its freely extended state is less than the minimum distance between the corresponding ends 111 of the two clamps 11, so that the elastic connector 32 is always in a stretched state.

[0041] The elastic connector 32 can be directly connected between the corresponding ends 111 of the two clamping members 11 and kept in a tensile state. The elastic connector 32 applies a tensile force to the corresponding ends 111 of the two clamping members 11, so that the two corresponding ends 111 are continuously subjected to a force that brings them closer together. Therefore, it is possible to easily prevent the load-bearing frame 1 from falling off the mounting column due to the relative displacement between the first limiting member 311 and the second limiting member 312, or the increase in the circumferential length of the load-bearing frame 1, by means of the elastic connector 32.

[0042] Under prolonged tension, the elasticity of the elastic connector 32 may fail. In this case, a cylinder or hydraulic cylinder can be used to replace the elastic connector 32 to connect and support the two clamps 11 between their corresponding ends 111, keeping the relative positions of the two corresponding ends 111 unchanged.

[0043] Optional, such as Figure 2 and Figure 3 As shown, Figure 2 and Figure 3 A schematic diagram of a clamp lamp 100 according to another embodiment of this application and Figure 2 In the enlarged view at point A, the connecting assembly 3 may also include a power cylinder 33. The power cylinder 33 has a cylinder body and a piston rod that can move relative to the cylinder body. The cylinder body and the piston rod are respectively connected to the corresponding ends 111 of the two clamping members 11. The power cylinder 33 may be a pneumatic cylinder or a hydraulic cylinder.

[0044] By connecting the power cylinder 33 with the limiting unit 31 between the corresponding ends 111 of the two clamping parts 11, it can be ensured that the relative positional relationship between the first limiting part 311 and the second limiting part 312 of the limiting unit 31 does not change, thereby preventing the length of the load-bearing frame 1 in the circumferential direction from changing, which would cause the load-bearing frame 1 to fall off the mounting column.

[0045] Optionally, the clamp light 100 may also include a pressure sensor, which can be disposed on the inner wall of the clamp 11 to monitor the pressure between the load-bearing frame 1 and the mounting column.

[0046] By setting a pressure sensor, the pressure between the load-bearing frame 1 and the mounting column can be obtained, thereby accurately controlling the limiting unit 31. This prevents the load-bearing frame 1 from being installed too tightly, which could damage the clamp 11 or the mounting column, or from being installed too loosely, which could lead to the clamp 100 detaching from the mounting column.

[0047] Optionally, an anti-slip pad 4 may be provided on the inner wall of the clamp 11. The anti-slip pad 4 may be completely attached to the inner wall of the clamp 11, or it may be attached to a part of the inner wall of the clamp 11. The anti-slip pad 4 may be made of engineering polymers with a high coefficient of friction (such as polyurethane, nitrile rubber) or vulcanized rubber.

[0048] Setting an anti-slip pad 4 on the inner wall of the clamp 11 can provide anti-slip capability and also protect the surface of the mounting column.

[0049] Optionally, there can be multiple anti-slip pads 4, and the multiple anti-slip pads 4 are arranged at equal intervals along the circumference of the clamp 11 on the inner wall of the clamp 11.

[0050] The multiple anti-slip pads 4, evenly distributed, ensure that the pressure of the load-bearing frame 1 is evenly transmitted to the entire circumference of the mounting column, thus providing a stable fixing effect. At the same time, the multiple anti-slip pads 4 are equivalent to establishing multiple high-friction anchoring points between the load-bearing frame 1 and the mounting column, which can more effectively resist the torque that causes the clamp lamp 100 to rotate or slide.

[0051] Optional, such as Figure 1 and Figure 2 As shown, a mounting plate 112 extending away from the center of the clamp 11 can be provided at one of the two opposite ends 111 of the two clamps 11. The two mounting plates 112 face each other, and the lamp 2 is fixed on the mounting plate 112.

[0052] By setting the mounting plate 112, the weight of the lamp 2 can be directly transferred to the load-bearing frame 1 through the mounting plate 112, avoiding the generation of additional bending moment or torque on the load-bearing frame 1, so that the overall structure of the clamp lamp 100 is stable.

[0053] Additionally, a mounting base for the luminaire 2 can be provided on the mounting plate 112 to meet the requirements for precise positioning of the light source and for light distribution, light intensity, and reliability. Furthermore, a cable tray 21 can be provided on the mounting plate 112 to accommodate the power and data cables for the luminaire 2.

[0054] The lamp 2 generates a large amount of heat during operation, affecting its lifespan and performance. Therefore, heat dissipation measures can be taken for the lamp 2. Optionally, the mounting plate 112 is equipped with heat sinks or a cooling fan. The heat sink can be installed on the surface of the mounting plate 112, with multiple fins integrally extended or fixed to increase the surface area in contact with air. The cooling fan can draw in surrounding air, accelerating airflow around the lamp 2 and achieving a heat dissipation effect.

[0055] Installing heat sinks or cooling fans on the mounting plate 112 can prevent the heat generated by the lamp 2 during operation from affecting the lifespan or performance of the lamp 2. At the same time, it prevents high temperatures from being conducted to the load-bearing frame 1, which could cause thermal expansion and deformation of the load-bearing frame 1 and affect the tightness of the load-bearing frame 1 to the mounting column.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
