Description

Technical Field

[0001] The utility model relates to the technical field of lamps, and particularly relates to a lamp assembly and a lighting device.

Background Art

[0002] An explosion-proof lamp is a lighting lamp with special design and functions, mainly used in environments where flammable and explosive gases or dust exist, to prevent electric arcs, sparks or high temperatures that may be generated inside the lamp from igniting the surrounding flammable environment, thus ensuring safety. In some usage scenarios, such as large workshops, warehouses, outdoor operation areas, etc., the illumination brightness of a single explosion-proof lamp is not sufficient to provide enough light, and its illumination range is limited, so multiple explosion-proof lamps need to be combined and connected for use.

[0003] However, the connection structures of some existing lamp assemblies are simple and unstable, which is not convenient for disassembling multiple groups of explosion-proof lamps.

Content of the Utility Model

[0004] To solve the technical problem of the unstable connection structure of the existing lamp assembly, the utility model provides a lamp assembly and a lighting device.

[0005] The solution of the utility model to solve the technical problem is to provide a lamp assembly. The lamp assembly includes a second connecting member and a first connecting member for connecting at least two lamps. The second connecting member passes through the gaps between at least two lamps and is detachably connected to at least two lamp bodies. The first connecting member passes through the through holes on at least two power boxes and connects at least two power boxes.

[0006] The lamp assembly further includes a mounting bracket and a third connecting member connecting the mounting bracket and the lamp body.

[0007] Preferably, the first connecting member is threadedly connected to the power box. The first connecting member includes a connecting rod and a nut threadedly engaged with the connecting rod.

[0008] Preferably, the first connecting member further includes a plugging member for plugging the through hole in cooperation with the nut.

[0009] Preferably, the through hole is provided on the side wall of the power box, and two symmetrical through holes are provided on the power box relative to the central axis of the lamp. The through holes are defined as a first through hole and a second through hole. One end of the first connecting member is threadedly connected to the power box through the first through hole, and one end is threadedly connected to the power box through the second through hole.

[0010] Preferably, a terminal block is provided inside the power supply box. Define the terminal block in one power supply box as the first terminal block, and the terminal block in the other power supply box as the second terminal block. The first terminal block and the second terminal block are connected by the first connecting member.

[0011] Preferably, the second connecting member is threadedly connected to the lamp body.

[0012] Preferably, there are at least two groups of the second connecting members, and the two groups of the second connecting members are symmetrically arranged with respect to the length direction axis of the lamp assembly.

[0013] Preferably, the length of the second connecting member is greater than the diameter of one lamp in the horizontal direction and less than the sum of the diameters of two lamps.

[0014] The present utility model further provides a lighting device, including the lamp assembly as described above. The mounting bracket includes a fourth connecting member that connects at least two groups of the lamp assemblies in the vertical direction.

[0015] Preferably, the fourth connecting member is threadedly connected to the third connecting member.

[0016] Compared with the prior art, a lamp assembly and a lighting device provided by the present utility model have the following advantages:

[0017] 1. For a lamp assembly provided by the present utility model, the second connecting member, the first connecting member and the third connecting member provide stable connection and support between two lamps. The second connecting member is connected through the gap of the lamp body, ensuring the overall structural stability of the lamp and not damaging the connection relationship between the lamp body and the power supply box; the first connecting member ensures the connection and electrical safety between the first connecting member and the power supply box through the through hole provided on the power supply box; the third connecting member connects the lamp body and the mounting bracket, making the installation process simpler and more efficient, and avoiding direct intervention on the lamp body.

[0018] 2. For a lamp assembly provided by the present utility model, the first connecting member provides stable connection for the power supply box arranged on one side of the lamp body. Usually, in order to achieve good heat dissipation effect between the lamp body and the power supply box, a gap is provided between the lamp body and the power supply box. Although the gap provides good heat dissipation, when multiple lamps are combined and connected, due to the existence of the gap, the connection between multiple power supply boxes relying only on the connection between the lamp bodies is slightly insufficient. Therefore, the first connecting member provides sufficient connection between different power supply boxes of multiple lamps, ensuring the normal use of multiple lamps after connection. At the same time, the threaded fit between the nut and the connecting rod provides tight fixation.

[0019] 3. A lamp assembly provided by the present utility model, the first connecting member further includes a plugging member that cooperates with the nut to plug the through hole. The plugging member ensures a tight fit with the nut. Using a plugging member made of high-strength, high-temperature resistant, and fireproof materials such as stainless steel, special alloy, or flame-retardant plastic can maintain stability under high-temperature and pressure conditions, completely seal the through hole, prevent gas or dust from entering the through hole, and reduce the explosion risk.

[0020] 4. A lamp assembly provided by the present utility model, two symmetrical through holes are connected. The first connecting member can evenly apply torque on both sides of the power supply box, evenly distribute the load, effectively disperse the stress from the first connecting member, and improve the stability and durability of the overall connection structure.

[0021] 5. A lamp assembly provided by the present utility model, the first connecting member enables the two power supply boxes to achieve mechanical connection through the through holes and connecting rods, and also provides an electrical parallel channel for the terminal blocks in the power supply boxes. The parallel configuration can simplify the wire routing in the power supply boxes, reduce complex wire connection steps, integrate the two lamps into a unified system, facilitate user use. Even if one power supply box fails, the system can still continue to operate through other power supply boxes, reducing the impact of single-point failures.

[0022] 6. A lamp assembly provided by the present utility model, the installation sequence of the second connecting member is after the third connecting member. After the third connecting member ensures the horizontal alignment between different lamps, it is threadedly connected to the lamp shade through the first connecting member to strengthen the connection stability between different lamps.

[0023] 7. A lamp assembly provided by the present utility model, there are at least two groups of the second connecting members, and they are symmetrically arranged with respect to the length direction of the lamp assembly, evenly distributing the force on the lamp assembly, reducing the structural stress caused by unbalanced loads, enhancing the overall stability. The symmetrical configuration enhances the strength, provides a larger support surface and resistance, and improves the durability and shock resistance of the lamp assembly.

[0024] 8. A lamp assembly provided by the present utility model, the second connecting member passes through two lamp bodies, and different parts thereof are threadedly connected to the two lamp bodies respectively. Therefore, the length of the second connecting member needs to be greater than the diameter of one lamp body and less than the sum of the diameters of the two lamp bodies. Being greater than the diameter of one lamp body ensures that the second connecting member has space to connect with both lamp bodies, while being less than the sum of the diameters of the two lamp bodies ensures that the second connecting member does not protrude beyond the area where the two lamp bodies are located, ensuring the aesthetics of the overall structure.

[0025] 9. The present utility model further provides a lighting device. The mounting bracket includes a fourth connecting member that connects at least two sets of the lamp assemblies in the vertical direction. The aforementioned first connecting member, second connecting member, and third connecting member all provide horizontal connections for different lamps, and can only ensure the horizontal series connection of multiple lamps. However, the fourth connecting member provides a vertical connection for the lamps, enabling the lamps to form an array arrangement, further increasing the illumination area and facilitating user use.

[0026] 10. The present utility model further provides a lighting device. The fourth connecting member is threadedly connected to the third connecting member. Threaded connection is applicable to a variety of materials and applications, can withstand large mechanical loads and pressures, and improves the durability of the lighting device.

[0044] Please refer to Figure 1 , to better illustrate the specific implementation manner of the lamp assembly, the lamp 200 will be described first here. The lamp 200 includes a lamp body 21 and a power supply box 22 provided on the lamp body 21. A through hole 24 is formed on the power supply box 22, and there is a gap 23 between the power supply box 22 and the lamp body 21.

[0045] Please refer to Figure 2 - Figure 4 , the first embodiment of the present utility model provides a lamp assembly 100. The lamp assembly 100 includes at least two horizontally connected lamps 200. The lamp assembly 100 includes a second connector 12 and a first connector 11 for connecting at least two lamps 200. The second connector 12 horizontally passes through the gap 23 and is detachably connected to at least two lamp bodies 21. The first connector 11 passes through the through holes 24 on at least two power supply boxes 22 and connects at least two power supply boxes 22; the lamp assembly 100 further includes a mounting bracket 14 and a third connector 13 connecting the mounting bracket 14 and the lamp body 21.

[0046] It can be understood that the second connector 12 realizes the horizontal connection of at least two lamps 200.

[0047] Specifically, the second connector 12 serves as the main connection and support part on the side of the lamp where the power supply box is provided. It cooperates with the first connector 11 passing through the through hole 24 of the power supply box 22 to form a complete and stable connection between two lamps 200. The mounting bracket 14 and the third connector 13 cooperate to share the weight of the two lamps, reduce the burden on other connectors, and fix the connected lamp assembly 100 at a predetermined position to ensure that the lamp assembly is stable and does not move during use.

[0048] Furthermore, the mounting bracket 14 and the third connector 13 are arranged on the same side as the first connector 11 and the second connector 12.

[0049] It can be understood that a lamp assembly 100 provided by the utility model is particularly suitable for explosion-proof lamps that are usually installed on ceilings or walls and are commonly seen in factory workshop warehouse scenes. It can be fixed on the wall through a mounting bracket 14. The explosion-proof lamp usually has a regular and symmetrical backlight surface and a low light surface. The first connecting member 11 and the second connecting member 12 are arranged away from the light source to prevent excessive connection structures from affecting the divergence of light. The third connecting member 13 is connected to the mounting bracket 14 while enhancing the contact stability between the lamps 200 and the lamps 200, reducing the impact of vibration on multiple connected lamps 200. The first connecting member 11, the second connecting member 12 and the third connecting member 13 are arranged in coordination, making it easier to align multiple lamps 200 when connected and coordinated, simplifying the installation process, and also meeting the requirements of explosion-proof lamps for light distribution and heat dissipation.

[0050] Specifically, the power box 22 is in a cubic shape, and the lamp body 21 is usually circular in design to accommodate a larger irradiation area. In order to achieve a good heat dissipation effect, a gap 23 is set between the lamp body 21 and the power box 22. The power box 22 is fixedly connected to the side of the lamp body 21 away from the light source by screws. Screws of different lengths and models form gaps 23 of different sizes. The second connecting member 12 passes through the gap 23 between at least two lamps 200 and is respectively connected to the two lamp bodies 21. The second connecting member 12 provides stable mechanical support between different lamp bodies 21 of the multiple lamps 200, which helps to keep the lamp bodies 21 of the multiple lamps 200 horizontally aligned during installation.

[0051] Specifically, in the present invention, the shape of the second connecting member 12 can be a long strip, an oblate circle or other special structures, as long as the second connection can pass through the gap 23 between the lamp body 21 and the power box 22, and provide sufficient stability and compatibility for connecting multiple lamps 200.

[0052] Furthermore, there are at least two groups of second connecting members 12 to improve the reliability of the connection between different lamp bodies 21 .

[0053] It can be understood that the use of the second connecting member 12 can simplify the installation process of multiple lamps 200, and the second connecting member 12 provides multiple centralized and stable connection points.

[0054] Specifically, see Figure 2 The two groups of second connecting members 12 are symmetrically arranged relative to the length direction of the lamp assembly 100.

[0055] Understandably, the two sets of second connectors 12 are respectively placed on both sides of the central axis in the length direction of the lamp assembly 100, symmetrically distributed in the horizontal direction. Each set of second connectors 12 is located on both sides of the central axis and at equal intervals. At the same time, the two sets of second connectors 12 should be installed parallel to each other in the horizontal direction, with the same size and shape, so as to maintain uniform stress and ensure the consistency and stability of the lamp assembly 100 after connection.

[0056] Preferably, the second connector 12 is threadedly connected to the lamp body 21. The second connector 12 passes through the gap 23 between at least two lamps 200 and is detachably connected to at least two lamp bodies 21, tightly fixing the second connector 12 to the lamp body 21 and being easy to disassemble and install.

[0057] Furthermore, the length of the second connector 12 is greater than the diameter of one lamp 200 in the horizontal direction and less than the sum of the diameters of two lamps 200.

[0058] Understandably, the length of the second connector 12 must be long enough to completely pass through the gap 23 between the lamp body 21 and the power supply box 22, and form sufficient contact area on two different lamp bodies 21 to make a firm connection with at least two lamp bodies 21, while being less than the sum of the diameters of two lamps 200 to keep the connection of the lamps 200 beautiful and tidy.

[0059] Furthermore, the power supply box 22 is connected in parallel with the lamp body 21. Two communicating through holes 24 are provided on the two side walls of the power supply box 22 in the horizontal direction, and the through holes 24 on adjacent different power supply boxes 22 are arranged correspondingly.

[0060] Specifically, please refer to Figure 4 , the first connector 11 includes a connecting rod 111 and a first nut 112 that cooperates with the connecting rod 111.

[0061] Specifically, the through hole 24 is provided on the side wall of the power supply box 22, and two symmetrical through holes 24 are provided on the power supply box 22 opposite to the central axis of the lamp 200. The through hole 24 is defined as a first through hole 241 and a second through hole 242. One end of the connecting rod 111 of the first connector 11 is threadedly connected to one power supply box 22 through the first through hole 241, and one end is threadedly connected to another power supply box 22 through the second through hole 242.

[0062] The first connector 11 further includes a plugging member 113 that cooperates with the first nut 112 to plug the through hole 24. The through hole 24 can be an extension protruding from the side wall surface of the power supply box 22 or a notch extending into the inner wall of the power supply box 22. No specific limitation is made in this embodiment.

[0063] Preferably, a first nut 112 with an appropriate thread specification is selected, such as an M26 first nut 112, etc. The plugging member 113 can be an aluminum plugging member 113 or other metal materials with good plugging performance, which is not specifically limited herein. By tightening the aluminum plugging member 113, compression is achieved, thereby realizing the fastening and sealing among the connecting rod 111, the first nut 112, and the through hole 24.

[0064] Furthermore, in the connection of two lamps 200, in addition to stabilizing the connection between the two lamps 200, the first connecting member 11 also serves to parallelize the two power boxes 22.

[0065] Furthermore, please refer to Figure 4 , a wiring terminal 221 is provided in the power box 22. It can be understood that during the connection process of the two lamps 200, in addition to the mechanical connection achieved through the second connecting member 12 and the third connecting member 13, the electrical connection between the wiring terminals 221 in the two power boxes 22 also needs to be realized.

[0066] Define the wiring terminal 221 in one power box 22 as the first wiring terminal 2211, and the wiring terminal 221 in the other power box 22 as the second wiring terminal 2212. The first wiring terminal 2211 and the second wiring terminal 2212 are electrically connected through the first connecting member 11.

[0067] Specifically, first, fix the third connecting member 13 to the lamp body 21. Secondly, pass the second connecting member 12 through the gap 23 between the two lamps 200 and fixedly connect it to the lamp body 21. Finally, the wire passes through the first through hole 241 of one power box and is connected to the first wiring terminal 2211 in the power box 22, and then sequentially passes through the plugging member 113, the second through hole 242, the connecting rod 111 of the same power box 22, and the first through hole 241 of the other power box 22 and enters the other power box 22 to be connected to the second wiring terminal 2212 in the other power box 22, realizing the parallel connection between the wiring terminals 221 of the two power boxes 22.

[0068] It can be understood that the wiring terminals 221 in the two power boxes 22 are paralleled through the through holes 24 and the connecting rod 111, simplifying the circuit wiring of the power box 22, reducing complex wire connection steps, integrating multiple power boxes 22 into a unified system, facilitating user use. Even if one power box 22 fails, the other lamp 200 can still continue to operate, reducing the impact of single-point failures.

[0069] It can be understood that the first connecting member 11 passes through two symmetrical through holes 24 on the power box 22 and connects multiple power boxes 22, effectively dispersing the connection force and enhancing the stability and durability of the mechanical connection.

[0070] Further, the connecting rod 111 and the plugging member 113 are hollow, facilitating the passing of wires.

[0071] Understandably, the wire passes through the plugging member 113 which is hollow, preventing gas or dust from entering the through hole 24. The plugging member 113 maintains the dryness and cleanliness of the internal environment of the power supply box 22, effectively isolating the wire from contact with other metal components, improving electrical safety and reducing the explosion risk.

[0072] Further, please refer to Figure 2 and Figure 3 , the third connecting member 13 is L-shaped, and the mounting bracket 14 is rotatably connected to the lamp body 21 through the third connecting member 13.

[0073] Furthermore, the mounting bracket 14 is detachable from the lamp body 21.

[0074] Understandably, the mounting bracket 14 improves the flexibility of use of the lamp assembly 100.

[0075] Specifically, the L-shaped third connecting member 13 has a long arm and a short arm. The long arm is fixed to the mounting bracket 14, and the short arm is fixedly connected to the lamp body. A connecting hole 131 and a rotating hole 132 are provided on the long arm connected to the mounting bracket 14. A second nut 133 is connected and provided corresponding to the rotating hole 132 on the mounting bracket 14. A sliding space for accommodating the sliding of the second nut 133 is provided in the rotating hole 132. The sliding space provides a certain angle of displacement, and the second nut 133 slides in the rotating hole 132 to achieve the rotational connection between the mounting bracket 14 and the third connecting member 13.

[0076] Specifically, the short arm and the lamp body 21 have a contact space with sufficient area, providing uniform support and connection and having a certain symmetry.

[0077] Preferably, the third connecting member 13 can also adopt threaded connection, snap connection or other fixing methods to achieve a stable connection between the third connecting member 13 and the mounting bracket 14.

[0078] Further, the lamp 200 further includes an upper cover, and the upper cover is arranged on the side of the lamp body 21 away from the power supply box 22.

[0079] Understandably, the upper cover seals the lamp body 21, protects the components inside the lamp body 21 such as important components like the light source, and prevents external environmental substances such as dust and water vapor from entering the inside of the lamp body 21.

[0080] Please refer to Figure 5 , the second embodiment of the present utility model provides an illumination device 300, including the lamp assembly 100 as described above.

[0081] Furthermore, a lighting device 300 provided in this embodiment is different from a lighting fixture assembly 100 provided in the first embodiment in that: the mounting bracket 14 includes a fourth connecting member 141 that connects at least two sets of lighting fixture assemblies 100 in the vertical direction, and a fixing member 142 fixedly connected to the fourth connecting member 141 on the fourth connecting member 141.

[0082] Furthermore, the fixing member 142 and the fourth connecting member 141 are connected to the central position of the fourth connecting member 141 in the horizontal direction relative to the lighting device 300.

[0083] It can be understood that placing the fixing member 142 at the central position can evenly distribute the force, enhance stability, reduce stress concentration, and facilitate fine adjustment during installation.

[0084] Specifically, the fixing member 142 and the fourth connecting member 141 are connected by threading.

[0085] It can be understood that a lighting fixture assembly 100 provided in the first embodiment provides connection stability in the horizontal direction for at least two lighting fixtures 200, and can only ensure the horizontal series connection of multiple lighting fixtures 200. However, the fourth connecting member 141 provided by the lighting device 300 provides connection in the vertical direction for multiple lighting fixtures 200, simplifies the installation process of multiple sets of lighting fixtures 200, enhances the stability of the lighting fixtures 200 in the vertical direction, enables the lighting fixtures 200 to form an array arrangement, avoids tilting or instability caused by gravity, forms a unified lighting system, provides a wider lighting coverage, and is suitable for places that require uniform lighting.

[0086] Compared with the prior art, a lighting fixture assembly and a lighting device provided by the present utility model have the following advantages:

[0087] 1. For a lighting fixture assembly provided by the present utility model, the second connecting member, the first connecting member, and the third connecting member provide a firm connection and support between two lighting fixtures. The second connecting member is connected through the gap of the lighting fixture body to ensure the overall structural stability of the lighting fixture without damaging the connection relationship between the lighting fixture body and the power supply box; the first connecting member ensures the connection and electrical safety between the first connecting member and the power supply box through the through hole provided on the power supply box; the third connecting member connects the lighting fixture body and the mounting bracket, making the installation process more simple and efficient, and avoiding direct interference with the lighting fixture body.

[0088] 2. A lamp assembly provided by the present utility model, the first connecting member provides a stable connection for the power supply box disposed on one side of the lamp body. Generally, in order to achieve a good heat dissipation effect between the lamp body and the power supply box, a gap is provided between the lamp body and the power supply box. Although the gap provides good heat dissipation, when multiple lamps are combined and connected, due to the existence of the gap, the connection between multiple power supply boxes relying only on the connection between the lamp bodies is slightly insufficient. Therefore, the first connecting member provides sufficient connection between different power supply boxes of multiple lamps to ensure the normal use after multiple lamps are connected. At the same time, the threaded fit between the nut and the connecting rod provides a tight fixation.

[0089] 3. A lamp assembly provided by the present utility model, the first connecting member further includes a plugging member that cooperates with the nut to plug the through hole. The plugging member ensures a tight fit with the nut. The plugging member made of materials such as stainless steel, special alloy or flame-retardant plastic with high strength, high temperature resistance and fire prevention can maintain stability under high temperature and pressure conditions, completely seal the through hole, prevent gas or dust from entering the through hole, and reduce the explosion risk.

[0090] 4. A lamp assembly provided by the present utility model, two symmetrical through holes are connected. The first connecting member can evenly apply torque on both sides of the power supply box, evenly distribute the load, effectively disperse the stress from the first connecting member, and improve the stability and durability of the overall connection structure.

[0091] 5. A lamp assembly provided by the present utility model, the first connecting member enables two power supply boxes to achieve mechanical connection through the through hole and the connecting rod, and also provides an electrical parallel connection channel for the wiring terminals in the power supply box. The parallel configuration can simplify the wire routing in the power supply box, reduce complex wire connection steps, integrate two lamps into a unified system, facilitate user use, and even if one power supply box fails, the system can still continue to operate through other power supply boxes, reducing the impact of single-point failures.

[0092] 6. A lamp assembly provided by the present utility model, the installation sequence of the second connecting member is after the third connecting member. After the third connecting member ensures the horizontal alignment between different lamps, it is threadedly connected to the lamp shade through the first connecting member to strengthen the connection stability between different lamps.

[0093] 7. A lamp assembly provided by the present utility model, there are at least two groups of the second connecting members, and they are symmetrically arranged with respect to the length direction of the lamp assembly, evenly distributing the force on the lamp assembly, reducing the structural stress caused by unbalanced loads, enhancing the overall stability. The symmetrical configuration enhances the strength, provides a larger supporting surface and resistance, and improves the durability and impact resistance of the lamp assembly.

[0094] 8. A lamp assembly provided by the present utility model, wherein a second connecting member passes through two lamp bodies and is threadedly connected to the two lamp bodies at different parts. Therefore, the length of the second connecting member needs to be greater than the diameter of one lamp body and less than the sum of the diameters of the two lamp bodies.
