Description

Technical Field

[0001] This utility model relates to the field of linear industrial and mining lamp technology, and more specifically, to an LED linear industrial and mining lamp. Background Technology

[0002] LED industrial and mining lamps are high-power lighting fixtures installed in large factories, warehouses, supermarkets, and other similar locations. Traditional industrial and mining lamps are generally divided into two types: circular and linear. Linear industrial and mining lamps typically consist of two LED light source components and a driver component, with the driver component installed between the two LED light source components. Because industrial and mining lamps generally have high power, the LED light source components and driver components generate significant heat. Therefore, existing industrial and mining lamps typically enlarge the LED light source components or incorporate multiple heat dissipation fins on the outer surface of the LED light source component's base (i.e., heat sink) to increase the heat dissipation area. Additionally, heat dissipation channels are often created between the LED light source components and the driver component.

[0003] However, the above-mentioned industrial and mining lamps still have the following problems:

[0004] 1. Increasing the area of ​​LED light source components will lead to increased costs;

[0005] 2. Due to the small distance between the LED light source component and the driver component, the heat generated by the two components will mix together, resulting in insufficient heat dissipation, which will affect the lifespan of the LED light source component and the driver component;

[0006] 3. Because the driving component is located between the two light source components, and the driving component is often large in order to match the light source components, a dark area will be formed on the driving component when the entire industrial and mining lamp is emitting light, resulting in uneven light output.

[0007] Therefore, a new solution is needed to address the above problems. Utility Model Content

[0008] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an LED linear industrial and mining lamp.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] An LED linear industrial and mining lamp includes a lamp body, a folding mechanism, and a power supply assembly. The lamp body includes at least two sets of LED light source assemblies, and a heat dissipation channel is provided between adjacent LED light source assemblies. The folding mechanism is installed between the lamp body and the power supply assembly. When the industrial and mining lamp is working, the folding mechanism unfolds to suspend the power supply assembly above the back of the lamp body. When the industrial and mining lamp is being packaged, the folding mechanism folds the power supply assembly to place it on one side of the back of the lamp body.

[0011] Furthermore, the lamp body includes a base and an LED light source assembly. The base has at least two sets of receiving cavities for mounting the LED light source assembly, and a heat dissipation channel is provided between adjacent receiving cavities. The LED light source assembly includes an LED light source board and a light-transmitting plate. The LED light source board is installed in the receiving cavity of the base, and the light-transmitting plate is installed above the LED light source board.

[0012] Furthermore, each set of the receiving cavities has two opposing inner sides provided with a first limiting plate and a second limiting plate for installing a light-transmitting plate. The light-transmitting plate is installed between the first limiting plate and the second limiting plate, and the upper and lower sides of the light-transmitting plate respectively abut against the first limiting plate and the second limiting plate.

[0013] Furthermore, one side of the base is provided with a notch for installing the cover plate, and the inner wall of the cover plate is provided with a third limiting plate for positioning its installation position, and a first buckle corresponding to the slot on the base. The cover plate is installed on one side of the base by the snap-fit ​​of the first buckle and the slot.

[0014] Furthermore, the folding mechanism includes a mounting plate and a folding plate for connecting the mounting plate and the power supply assembly, the mounting plate being mounted on the back of the base on the lamp body.

[0015] Furthermore, the mounting plate has an L-shaped structure, with the horizontal section of the mounting plate mounted on the back of the base, the vertical section of the mounting plate hinged to one end of the folding plate, and the other end of the folding plate hinged to the power supply assembly.

[0016] Furthermore, the folding plate includes a first connecting plate connected to the mounting plate, a second connecting plate connected to the power supply assembly, and a third connecting plate connected between the first connecting plate and the second connecting plate, wherein the first connecting plate and the second connecting plate are not located on the same plane.

[0017] Furthermore, the folding mechanism also includes a limiting component, which includes a baffle and a guide block. The guide block is located on one side of the baffle and has an inclined surface for the folding plate to pass over. The folding plate passes over the guide block by rotation and is constrained between the baffle and the guide block.

[0018] Furthermore, the power supply assembly includes a power supply box and a drive power supply installed inside the power supply box. The power supply box has a heat dissipation groove on its side and wiring holes on its side and top.

[0019] Furthermore, it also includes a sensor assembly, which includes a sensor and a mounting bracket. The mounting bracket includes a horizontal mounting part for mounting the sensor and a vertical mounting part for connecting to the lamp body. The sensor is screwed into the mounting hole of the horizontal mounting part. The vertical mounting part is provided with a hook. The horizontal mounting part is provided with a second buckle on the side facing the lamp body. The mounting bracket is installed on the lamp body by hooking onto the upper side wall of the lamp body and the second buckle engaging with the lower side wall of the lamp body.

[0020] The beneficial effects of this utility model are:

[0021] 1. In this utility model, by setting a folding mechanism between the lamp body and the power supply component, when the industrial and mining lamp is working, the folding mechanism is unfolded to suspend the power supply component above the lamp body and away from the lamp body, so that the heat dissipation of the lamp body and the power supply component do not affect each other, and the power supply component will not interfere with the light emission of the lamp body, making the light emission of the lamp body more uniform; when packaging, the folding mechanism is used to fold the power supply component to place it on one side of the back of the lamp body, so as to reduce the volume of the packaging box.

[0022] 2. In this utility model, heat dissipation channels are set between adjacent LED light source components to enhance the heat dissipation effect of the LED light source components. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example: An LED linear industrial and mining lamp, such as Figures 1-9 As shown, the lamp includes a lamp body 1, a folding mechanism 2, and a power supply assembly 3. The lamp body 1 includes at least two sets of LED light source assemblies 12, and a heat dissipation channel 14 is provided between adjacent LED light source assemblies 12 to dissipate the heat generated by the LED light source assemblies 12 during operation. The folding mechanism 2 is installed between the lamp body 1 and the power supply assembly 3, and the folding mechanism 2 has two states: unfolded and retracted.

[0035] When the industrial and mining lamp is working, such as Figure 6 As shown, unfolding the folding mechanism 2 allows the power supply component 3 to suspend above the back of the lamp body 1. On one hand, by distancing the lamp body 1 and the power supply component 3, their heat dissipation is prevented from interfering with each other. On the other hand, placing the power supply component 3 on the back of the lamp body 1 prevents interference when the lamp body 1 is emitting light. When packaging industrial and mining lamps, such as... Figure 7 As shown, by folding the folding mechanism 2, the power supply assembly 3 is placed on one side of the back of the lamp body 1, thereby reducing the volume of the packaging box.

[0036] Furthermore, such as Figure 2As shown, the lamp body 1 includes a base 11, an LED light source assembly 12, and a cover plate 15 installed on one side of the base 11. The base 11 has a rectangular structure and can be integrated. The base 11 has at least two sets of receiving cavities 13 for installing the LED light source assembly 12. A heat dissipation channel 14 is provided between adjacent receiving cavities 13. Each set of receiving cavities 13 is provided with one set of LED light source assembly 12.

[0037] The LED light source assembly 12 includes an LED light source board 121 and a light-transmitting plate 122. The LED light source board 121 is installed inside the receiving cavity 13 of the base 11, and the light-transmitting plate 122 is installed above the LED light source board 121. Specifically:

[0038] The LED light source board 121 is fixedly mounted on the inner bottom wall of the receiving cavity 13 by screws. Each set of receiving cavities 13 has two opposite inner sides provided with a first limiting plate 131 and a second limiting plate 132 for mounting the light-transmitting plate 122. The first limiting plate 131 is located above the second limiting plate 132. The area between the first limiting plate 131 and the second limiting plate 132 is formed for mounting the light-transmitting plate 122. When the light-transmitting plate 122 is mounted between the first limiting plate 131 and the second limiting plate 132, the upper and lower sides of the light-transmitting plate 122 respectively abut against the first limiting plate 131 and the second limiting plate 132. The light-transmitting plate 122 is constrained by the cooperation of the first limiting plate 131 and the second limiting plate 132 and is limited above the LED light source board 121.

[0039] like Figure 2 and Figure 3 As shown, a notch 111 for mounting the cover plate 15 is provided on one side of the base 11. A third limiting plate 151 is provided on the inner wall of the cover plate 15. The installation position of the cover plate 15 can be positioned by the third limiting plate 151, so that the first buckle 152 on the cover plate 15 corresponds to the slot 112 on the base 11, thereby facilitating the first buckle 152 to engage with the slot 112.

[0040] like Figure 3 As shown, the inner wall of the cover plate 15 is provided with multiple sets of first buckles 152, and the base 11 is provided with a slot 112 that is compatible with the first buckles 152. The cover plate 15 is fixedly installed on one side of the base 11 through the snap-fit ​​of the first buckles 152 and the slot 112.

[0041] When the light-transmitting plate 122 needs to be replaced, firstly, the first buckle 152 on the cover plate 15 is disengaged from the slot 112, then the cover plate 15 is removed from the base 11, and then the light-transmitting plate 122 is removed from the area formed by the combination of the first limiting plate 131 and the second limiting plate 132 for replacement; when the faulty LED light source board 121 needs to be replaced, after removing the light-transmitting plate 122, the LED light source board 121 is disassembled from the receiving cavity 13 for replacement, which is convenient to operate.

[0042] As a preferred option, such as Figure 2 As shown, the heat dissipation channel 14 is provided with multiple sets of partitions 141, which divide the entire heat dissipation channel 14 into multiple small heat dissipation channel units 14. By setting the partitions 141, on the one hand, the heat dissipation area of ​​the heat dissipation channel 14 can be increased, heat dissipation can be accelerated, and heat dissipation effect can be improved; on the other hand, adjacent receiving cavities 13 can be connected to enhance the stability between adjacent receiving cavities 13.

[0043] Preferably, a heat sink is provided on the back of the base 11 to increase the heat dissipation area of ​​the base 11 and accelerate the heat dissipation of the LED light source board 121.

[0044] Furthermore, such as Figure 1 As shown, the folding mechanism 2 has two sets, located on the left and right sides of the power supply assembly 3 respectively; when the power supply assembly 3 is suspended, both sets of folding mechanisms 2 unfold simultaneously to improve the stability of the power supply assembly 3 when suspended. Figure 4 As shown, each folding mechanism 2 includes a mounting plate 21 and a folding plate 22 for connecting the mounting plate 21 and the power supply assembly 3. The mounting plate 21 is mounted on the back of the base 11.

[0045] The mounting plate 21 has an L-shaped structure, including a horizontal section and a vertical section. The horizontal section of the mounting plate 21 is mounted on the back of the base 11, and the vertical section of the mounting plate 21 is hinged to one end of the folding plate 22. The other end of the folding plate 22 is hinged to the power supply assembly 3. Specifically:

[0046] The horizontal section of the mounting plate 21 has a through hole 211, and the back of the base 11 has a mounting post 113. A screw passes through the through hole 211 and is threaded onto the mounting post 113 to fix the horizontal section of the mounting plate 21 onto the back of the base 11. One end of the folding plate 22 is mounted on the vertical section of the mounting plate 21 by a rivet or bolt, and can rotate on the vertical section of the mounting plate 21 around the rivet or bolt. The other end of the folding plate 22 is mounted on the power supply assembly 3 by a rivet or bolt, and can rotate on the power supply assembly 3 around the rivet or bolt.

[0047] like Figure 4As shown, each folding mechanism 2 has two sets of folding plates 22, which simultaneously support the power assembly 3 to improve the stability of the power assembly 3 when suspended. Each set of folding plates 22 includes a first connecting plate 221 connected to the vertical section of the mounting plate 21 and a second connecting plate 222 connected to the power assembly 3. At the same time, when the folding mechanism 2 is folded up, in order to avoid interference between the second connecting plate 222 of one set of folding plates 22 and the first connecting plate 221 of the other set of folding plates 22, which would cause the folding mechanism 2 to not fold up properly and thus prevent the power assembly 3 from being placed on the back of the base 11, a third connecting plate 223 is provided between the first connecting plate 221 and the second connecting plate 222. The third connecting plate 223 is inclined outward, and its two ends are respectively connected to the first connecting plate 221 and the second connecting plate 222.

[0048] By setting an outwardly inclined third connecting plate 223, the first connecting plate 221 and the second connecting plate 222 in the same group of folding plates 22 are not located on the same plane. This prevents interference between the second connecting plate 222 of one group of folding plates 22 and the first connecting plate 221 of another group of folding plates 22 when the folding mechanism 2 is closed. Figure 7 As shown; at the same time, as Figure 9 As shown, by utilizing the fact that the first connecting plate 221 and the second connecting plate 222 are not located on the same plane, it is convenient for the two sets of industrial and mining lamps to be placed together in opposite directions. That is, when the two sets of industrial and mining lamps are placed together in opposite directions, the first connecting plate 221 on one set of industrial and mining lamps will not interfere with the second connecting plate 222 on the other set of industrial and mining lamps.

[0049] Furthermore, such as Figure 4 As shown, the folding mechanism 2 also includes a limiting component 23, which includes a baffle 231 and a guide block 232. The guide block 232 is located on one side of the baffle 231. The baffle 231 and the guide block 232 work together to constrain the vertical folding plate 22, keeping the folding mechanism 2 in the unfolded state, thereby maintaining the suspended state of the power supply component 3. The limiting component 23 can be installed on the power supply component 3 or on the mounting plate 21.

[0050] The guide block 232 is provided with an inclined surface 2321 for the folding plate 22 to pass over. There are two sets of inclined surfaces 2321 arranged opposite to each other. One set of inclined surfaces 2321 is used for the folding plate 22 to pass between the guide block 232 and the baffle 231, and the other set of inclined surfaces 2321 is used for the folding plate 22 to pass out between the guide block 232 and the baffle 231. The two sets of inclined surfaces 2321 on the guide block 232 are used to realize the switching between the unfolded and retracted states of the folding mechanism 2.

[0051] A region adapted to the folding plate 22 is formed between the guide block 232 and the baffle 231. When the folding plate 22 rotates, it can move along the surface of the guide block 232. After passing the guide block 232, the folding plate 22 moves into the region formed by the guide block 232 and the baffle 231, and is limited between the guide block 232 and the baffle 231 by its two sides respectively abutting against the guide block 232 and the baffle 231. At this time, due to the obstruction of the baffle 231, the folding plate 22 cannot continue to rotate in the same direction, and the power supply assembly 3 is suspended directly above the lamp body 1. To improve the limiting effect of the folding plate 22, the inclination of the other set of inclined surfaces 2321 is controlled. While ensuring that the folding plate 22 can pass between the guide block 232 and the baffle 231, the inclination of the other set of inclined surfaces 2321 is increased as much as possible.

[0052] Furthermore, such as Figure 5 As shown, the power supply assembly 3 includes a power supply box 31 and a drive power supply 32 installed in the power supply box 31. The side of the power supply box 31 is provided with a heat dissipation groove 311 for heat dissipation. The side and top of the power supply box 31 are provided with wiring holes 312. The mains power wire and the drive power supply 32 wire are connected to the drive power supply 32 and the LED light source board 121 respectively through the wiring holes 312.

[0053] Furthermore, such as Figure 1 and Figure 8 As shown, to enhance the energy-saving effect of the industrial and mining lamp, a sensor assembly 4 is also provided on the lamp. The sensor assembly 4 is detachably installed on one side of the lamp. The sensor assembly 4 includes a sensor 41 and a mounting bracket 42. The mounting bracket 42 serves as the mounting carrier for the sensor 41, and the sensor 41 is installed on the lamp through the mounting bracket 42. The sensor 41 can be one of infrared sensing, microwave sensing, or radar sensing. When the sensor 41 detects someone passing under the lamp, the lamp will light up or be in a high-brightness state. When the sensor 41 does not detect anyone under the lamp within a certain period of time, the lamp will be off or dimly lit.

[0054] like Figure 8As shown, the mounting bracket 42 includes a horizontal mounting portion 421 for mounting the sensor 41 and a vertical mounting portion 422 for connecting to the lamp body 1. The horizontal mounting portion 421 has a mounting hole 4211 adapted to the sensor 41. The inner surface of the mounting hole 4211 has an internal thread, and the sensor 41 has an external thread. The sensor 41 is screwed into the mounting hole 4211 by the thread. The vertical mounting portion 422 has a hook 4221, and the side of the horizontal mounting portion 421 facing the lamp body 1 has a second buckle 4212. When the mounting bracket 42 is installed on the industrial lamp, the hook 4221 is hooked on the upper side wall of the base 11, and the second buckle 4212 is snapped on the lower side wall of the base 11. After installation, the sensor connection wire on the power supply assembly 3 is connected to the sensor 41.

[0055] When using the above-mentioned industrial and mining lamp, rotate the folding plate 22 to move it along the surface of the guide block 232. After passing the guide block 232, the folding plate 22 is limited between the guide block 232 and the baffle 231. At this time, the power supply assembly 3 is suspended directly above the lamp body 1. If it is necessary to install the sensor assembly 4, install the sensor assembly 4 on the side of the industrial and mining lamp, and connect the drive power supply 32 to the sensor 41 through the sensor connection wire. Figure 1 and Figure 6 As shown; during packaging, if sensor assembly 4 is installed, first remove sensor assembly 4 from the industrial lamp, then reverse the folding plate 22 so that it passes over the guide plate, then rotate the folding plate 22 in the opposite direction so that the power supply assembly 3 is placed on one side of the back of the lamp body 1, as shown. Figure 7 As shown, then perform the same operation on the other set of working lights, and place them in reverse on top of the previous working light, as shown. Figure 9 As shown, the two mining lamps stacked together are then placed into the same packaging box.

[0056] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
