Description

Technical Field

[0001] This invention relates to a lighting device, and more particularly to a high-efficiency industrial lighting device. Background Technology

[0002] Existing industrial and mining lamps generally use spherical lenses, but spherical lenses need to be manufactured through an injection molding process. Therefore, to ensure that the curvature of the lens surface meets the design requirements, a long holding time is required, which significantly increases the manufacturing cost of industrial and mining lamps.

[0003] In addition, the assembly process for spherical lenses is quite complex. Whether it is installed by clips or fixed with screws, it requires a lot of manpower, which further increases the manufacturing cost of industrial and mining lamps.

[0004] In addition, insufficient holding time during the injection molding process will greatly affect the light emission angle of the spherical lens, and also affect the brightness of the industrial and mining lamp. Summary of the Invention

[0005] According to an embodiment of the present invention, a high-efficiency industrial lighting device is provided, comprising at least one lighting module. The lighting module includes a base, a light source plate, and a lens. The light source plate is disposed on the base. The lens is disposed on the base and covers the light source plate. The lens includes an optical module, which includes a central portion and two side portions. The two side portions are respectively disposed on both sides of the central portion, forming an accommodating space between the central portion and the two side portions. The light source plate is located in the accommodating space and faces the central portion.

[0006] In one embodiment, the curvature of the side of the central portion adjacent to the light source plate is smaller than the curvature of the other side of the central portion.

[0007] In one embodiment, the side portion includes an incident surface, a reflecting surface, and an emitting surface. Light emitted from the light source plate passes through the incident surface, is then reflected by the reflecting surface, and finally passes through the emitting surface.

[0008] In one embodiment, the angle between the incident surface and the vertical reference line is smaller than the angle between the reflecting surface and the vertical reference line.

[0009] In one embodiment, the side portion further includes a first connecting surface, a second connecting surface, and a third connecting surface. The first connecting surface is located between the light-incident surface and the reflective surface and contacts the base. The second connecting surface is located between the light-incident surface and the light-emitting surface and is connected at the center. The third connecting surface is located between the reflective surface and the light-emitting surface.

[0010] In one embodiment, the lens further includes two arcuate arms. One arcuate arm is connected to a third connecting surface of one of the side portions, while the other arcuate arm is connected to a third connecting surface of the other side portion.

[0011] In one embodiment, the base includes a housing and a base plate connected to each other. A cavity is formed between the housing and the base plate, and the two sides of the housing are respectively fitted into the two arc-shaped arms.

[0012] In one embodiment, the industrial lighting device further includes two side covers. The side covers are respectively disposed at both ends of the base.

[0013] In one embodiment, the industrial lighting device further includes a bracket. Both ends of the bracket are connected to the aforementioned side covers.

[0014] In one embodiment, the industrial lighting device further includes two-way adjustment plates. Both ends of the bracket are connected to the two side covers via these two-way adjustment plates.

[0015] As described above, the high-efficiency industrial lighting device according to embodiments of the present invention may have one or more of the following advantages:

[0016] (1) In one embodiment of the present invention, the industrial lighting device includes at least one lighting module. The lighting module includes a base, a light source plate, and a lens. The light source plate is disposed on the base. The lens is disposed on the base and covers the light source plate. The lens includes an optical module, which includes a central portion and two side portions. The two side portions are respectively disposed on both sides of the central portion, forming an accommodating space between the central portion and the two side portions. The light source plate is located in the accommodating space and faces the central portion. The curvature of the side of the central portion adjacent to the light source plate is smaller than the curvature of the other side of the central portion. The side portions include a light-incident surface, a reflective surface, and a light-exiting surface. The light emitted by the light source plate passes through the light-incident surface and is then reflected by the reflective surface, and then passes through the light-exiting surface. Therefore, the central portion can achieve a light-focusing effect, while the two side portions can achieve a reflective effect. Through the above-mentioned composite optical structure and the design of the asymmetrical central portion, the light-focusing effect of the optical module can be greatly improved to reduce light loss, so that the light emitted by the light source plate can be uniformly concentrated on the target area. Therefore, the luminous efficacy and brightness of the industrial lighting device can be greatly improved.

[0017] (2) In one embodiment of the present invention, the lens of the illumination module includes an optical module, and the side portion of the optical module further includes a first connecting surface, a second connecting surface, and a third connecting surface. The first connecting surface is located between the light-incident surface and the reflective surface and contacts the base. The second connecting surface is located between the light-incident surface and the light-emitting surface and is connected at the center. The third connecting surface is located between the reflective surface and the light-emitting surface. Through the above structural design, the lens can be fixed on the base, so that there is a distance between the central part of the optical module and the light source board, thereby ensuring that the performance of the above-mentioned composite optical structure can be optimized.

[0018] (3) In one embodiment of the present invention, the lens of the lighting module includes two arc-shaped arms. One arc-shaped arm is connected to a third connecting surface of one side portion, and the other arc-shaped arm is connected to a third connecting surface of another side portion. The base includes a housing and a base plate connected to each other, with the two sides of the housing respectively fitted into the two arc-shaped arms. Through the above structural design, there can be a distance between the two arc-shaped arms and the base plate to provide some flexible space for the assembly process, effectively compensating for processing errors and improving the assembly effect, thereby reducing the need for manpower. Therefore, the industrial lighting device can effectively reduce manufacturing costs.

[0019] (4) In one embodiment of the present invention, the base of the lighting module includes a housing and a base plate connected to each other. A cavity is formed between the housing and the base plate, which can be used to accommodate the power module, wires, and other necessary components. Thus, users can place additional components in the cavity according to actual needs. Therefore, the use of industrial lighting devices can be more flexible and the applications can be more extensive.

[0020] (5) In one embodiment of the present invention, the base of the lighting module includes a housing and a base plate connected to each other. The surface of the housing has multiple grooves. These multiple grooves can effectively increase the heat dissipation area, thereby significantly improving the heat dissipation efficiency of the lighting module. In this way, the service life of the industrial lighting device can be greatly extended. In addition, the multiple grooves can also achieve a scratch-resistant effect, making scratches on the housing less noticeable. Therefore, the industrial lighting device is more in line with the needs of practical applications.

[0021] (6) In one embodiment of the present invention, the industrial lighting device further includes two side covers and two directional adjustment plates. The two side covers are respectively disposed at both ends of the base, and both ends of the bracket are respectively connected to the two side covers through the two directional adjustment plates. Through the structural design of the directional adjustment plates, the user can appropriately adjust the illumination angle of the industrial lighting device. Therefore, the industrial lighting device can meet the needs of different applications. Attached Figure Description

For ease of understanding, the same components in the following embodiments are indicated by the same symbols.

[0036] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 . Figure 1 A combination diagram of a high-efficiency industrial lighting device according to an embodiment of the present invention. Figure 2 An exploded view of a high-efficiency industrial lighting device according to an embodiment of the present invention. Figure 3 A side view of the light source plate of a high-efficiency industrial lighting device according to an embodiment of the present invention. Figure 4 A perspective view of a lens of a high-efficiency industrial lighting device according to an embodiment of the present invention. As shown, the industrial lighting device 1 includes multiple lighting modules 11, two side covers 12, a bracket 13, and two-way adjustment plates 14. One end of each lighting module 11 is fixed to one side cover 12, and the other end is fixed to the other side cover 12. Both ends of the bracket 13 are connected to the two side covers 12 via the two-way adjustment plates 14. In this embodiment, the industrial lighting device 1 has four lighting modules 11. In another embodiment, the industrial lighting device 1 may have only one lighting module 11 or more than four lighting modules 11. The number of lighting modules 11 can be adjusted according to actual needs. In another embodiment, both ends of the bracket 13 may also be directly connected to the two side covers 12.

[0037] Each lighting module 11 includes a base 111, two light source boards 112, and a lens 113. The two light source boards 112 are mounted on the base 111. The two side covers 12 are respectively mounted at both ends of the base 111. Each light source board 112 includes a circuit board 1121 and multiple light sources 1122. The multiple light sources 1122 can be light-emitting diodes (LEDs). In addition, each lighting module 11 also includes two sealing gaskets 114. The two sealing gaskets 114 are respectively mounted at both ends of the lens 113 to achieve waterproof and dustproof effects.

[0038] Lens 113 is disposed on base 111 and covers light source plate 112. Lens 113 includes two optical modules 1131 and two arc-shaped arms 1132. The two optical modules 1131 correspond to the two light source plates 112 respectively. In another embodiment, lens 113 may include only one optical module 1131 or more than two optical modules 1131 (the number of light source plates 112 is the same as the number of optical modules 1131). The number of optical modules 1131 can be adjusted according to actual needs. Lens 113 can be made of transparent or translucent materials, such as plastic, glass, etc.

[0039] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the high-efficiency industrial lighting device according to this embodiment should still be included within the patent scope of the invention.

[0040] Please see Figure 5 and Figure 6 Please also refer to Figures 1 to 4 . Figure 5 This is a cross-sectional view of the optical module of a lens in a high-efficiency industrial lighting device according to an embodiment of the present invention. Figure 6 This is a partially enlarged view of the optical module of a lens in a high-efficiency industrial lighting device according to an embodiment of the present invention. As shown, each optical module 1131 includes a central portion CP and two side portions LP. The two side portions LP are respectively disposed on both sides of the central portion CP, forming an accommodating space between the central portion CP and the two side portions LP. The light source plate 112 corresponding to this optical module 1131 is disposed in the accommodating space and faces the central portion CP.

[0041] Taking the optical module 1131 on the left as an example, the curvature of the side S1 of the central portion CP of this optical module 1131 adjacent to the light source plate 112 is smaller than the curvature of the other side S2 of the central portion CP; therefore, the optical module 1131 adopts an asymmetrical structural design and is not limited by the holding time. The side portion LP on the left side of this optical module 1131 includes an incident light surface IS, a reflecting surface FS, an emitting light surface ES, a first connecting surface CS1, a second connecting surface CS2, and a third connecting surface CS3 that are interconnected. The first connecting surface CS1 is located between the incident light surface IS and the reflecting surface FS and is in contact with the base 111. The second connecting surface CS2 is located between the incident light surface IS and the emitting light surface ES and is connected to the central portion CP. The third connecting surface CS3 is located between the reflecting surface RF and the emitting light surface ES and is connected to one of the arc-shaped arms 1132. The angle θ1 between the incident light surface IS and the vertical reference line VR is smaller than the angle θ2 between the reflecting surface FS and the vertical reference line VR.

[0042] The right-side portion LP (the other side portion LP of this optical module 1131) also has the same structure. However, since the lens 113 in this embodiment has two optical modules 1131, the third connecting surface CS3 of the right-side portion LP of this optical module 1131 is connected to the right-side optical module 1131, and the right-side optical module 1131 is connected to another arc-shaped arm 1132. If the lens 113 has only one optical module 1131, the third connecting surface CS3 of the right-side portion LP of this optical module 1131 is connected to another arc-shaped arm 1132. The number of optical modules 1131 can vary according to actual needs; in another embodiment, the lens 113 may also have three or more optical modules 1131.

[0043] Through the above structural design, the lens 113 can be fixed on the base 111, so that there is a distance between the central part CP of the optical module 1131 and the light source plate 112.

[0044] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the high-efficiency industrial lighting device according to this embodiment should still be included within the patent scope of the invention.

[0045] Please see Figure 7 This is a schematic diagram illustrating the operational state of the optical module of the lens in a high-efficiency industrial lighting device according to an embodiment of the present invention. Please also refer to... Figures 5 to 6 As shown in the figure, a portion of the light emitted by the light source plate 112 (as indicated by arrow A1 in the figure) passes through the central part CP. After passing through the central part CP, the light emitted by the light source plate 112 will concentrate towards the center to a certain extent, thereby achieving a focusing effect.

[0046] Another portion of the light emitted from the light source plate 112 passes through the two side portions LP mentioned above. This other portion of the light emitted from the light source plate 112 passes through the incident surface IS of either side portion LP, is reflected by its reflecting surface FS, and then passes through its exit surface ES. As mentioned earlier, the angle θ2 between the reflecting surface FS and the vertical reference line VR is greater than the angle θ1 between the incident surface IS and the vertical reference line VR. Thus, when the light reaches the reflecting surface FS, the angle of incidence of this light can be greater than the critical angle, so the light will not pass through the reflecting surface FS, but will be reflected by the reflecting surface FS (total internal reflection). The light will also concentrate towards the center to some extent. Because the two side portions LP are symmetrical, the light can be made more uniform.

[0047] As described above, the central portion CP of each optical module 1131 achieves a light-focusing effect, while its two side portions LP achieve a reflective effect. Through the aforementioned composite optical structure and the design of the asymmetrical central portion CP, the light-focusing effect of the optical module 1131 can be significantly improved to reduce light loss, allowing the light emitted by the light source board 112 to be uniformly concentrated on the target area. Therefore, the luminous efficacy and brightness of the industrial lighting device 1 can be significantly improved.

[0048] As mentioned above, the lens 113 of the illumination module 11 includes an optical module 1131, and the side portion LP of the optical module 1131 further includes a first connecting surface C1, a second connecting surface C2, and a third connecting surface C3. The first connecting surface C1 is located between the incident light surface IS and the reflecting surface FS and contacts the base 111. The second connecting surface C2 is located between the incident light surface IS and the emitting light surface ES and is connected to the central portion CP. The third connecting surface C3 is located between the reflecting surface FS and the emitting light surface ES. Through the above structural design, the lens 113 can be fixed on the base 111, so that there is a distance between the central portion CP of the optical module 1131 and the light source plate 112, thereby ensuring that the performance of the above-mentioned composite optical structure can be optimized.

[0049] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the high-efficiency industrial lighting device according to this embodiment should still be included within the patent scope of the invention.

[0050] Please see Figure 8 This is a schematic diagram of the lighting module of a high-efficiency industrial lighting device according to an embodiment of the present invention. As shown, the base 111 of the lighting module 11 includes a housing 1111 and a base plate 1112 connected to each other. A cavity EB is formed between the housing 1111 and the base plate 1112. This cavity EB can be used to accommodate the power module, wires, and other necessary components. Thus, the user can install additional components in the cavity EB according to actual needs. Therefore, the industrial lighting device 1 can be used more flexibly and its application can be more extensive.

[0051] The housing 1111 has two flanges PN, which are respectively disposed on both sides of the housing 1111. Each arcuate arm 1132 has a slot LT on one side, which corresponds to one of the flanges PN. Each flange PN can be engaged with the corresponding slot LT. Therefore, both sides of the housing 1111 can be engaged with the two arcuate arms 1132 respectively.

[0052] The base plate 1112 includes a central flat plate M1 and two oblique wings M2, with the two oblique wings M2 respectively disposed on both sides of the central flat plate M1. Thus, the shape of the base plate 1112 can match the shape of the lens 113. Through the above structural design, a distance can be provided between the two arc-shaped arms 1132 and the base plate 1112, providing some flexibility for the assembly process, effectively compensating for processing errors, improving assembly efficiency, and reducing manpower requirements. Therefore, the industrial lighting device 1 can effectively reduce manufacturing costs.

[0053] On the other hand, the surface of the housing 1111 has multiple grooves GV. These grooves GV effectively increase the heat dissipation area, significantly improving the thermal efficiency of the lighting module 11. This greatly extends the service life of the industrial lighting device 1. Furthermore, the grooves GV also provide scratch resistance, making scratches on the housing 1111 less noticeable. Therefore, the industrial lighting device 1 better meets the needs of practical applications.

[0054] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the high-efficiency industrial lighting device according to this embodiment should still be included within the patent scope of the invention.

[0055] It is worth mentioning that existing industrial and mining lamps generally use spherical lenses, but spherical lenses need to be manufactured through an injection molding process. Therefore, to ensure that the curvature of the lens surface meets the design requirements, a long holding time is required, which significantly increases the manufacturing cost of industrial and mining lamps. In addition, the assembly process of spherical lenses is relatively complex. Whether it is installation by snap-fit ​​or fixing by screws, it requires a lot of manpower, which further increases the manufacturing cost of industrial and mining lamps. Furthermore, if the holding time of the injection molding process is insufficient, it will have a significant impact on the light emission angle of the spherical lens, and at the same time affect the brightness of the industrial and mining lamp. In contrast, according to an embodiment of the present invention, the industrial lighting device includes at least one lighting module. The lighting module includes a base, a light source plate, and a lens. The light source plate is disposed on the base. The lens is disposed on the base and covers the light source plate. The lens includes an optical module, and the optical module includes a central portion and two side portions. The two side portions are respectively disposed on both sides of the central portion, so that an accommodating space is formed between the central portion and the two side portions. The light source plate is located in the accommodating space and faces the central portion. The curvature of the central section adjacent to the light source board is smaller than that of the other side of the central section. The side sections include an incident surface, a reflecting surface, and an emitting surface. Light emitted from the light source board passes through the incident surface, is reflected by the reflecting surface, and then passes through the emitting surface. Therefore, the central section achieves a focusing effect, while the aforementioned side sections achieve a reflecting effect. Through the aforementioned composite optical structure and the asymmetrical central section design, the light concentration effect of the optical module can be significantly improved to reduce light loss, allowing the light emitted from the light source board to be uniformly concentrated on the target area. Therefore, the luminous efficacy and brightness of the industrial lighting device can be significantly improved.

[0056] According to an embodiment of the present invention, the lens of the illumination module includes an optical module, and the side portion of the optical module further includes a first connecting surface, a second connecting surface, and a third connecting surface. The first connecting surface is located between the light-incident surface and the reflective surface and contacts the base. The second connecting surface is located between the light-incident surface and the light-emitting surface and is centrally connected. The third connecting surface is located between the reflective surface and the light-emitting surface. Through the above structural design, the lens can be fixed on the base, so that there is a distance between the central portion of the optical module and the light source board, thereby ensuring that the performance of the above-mentioned composite optical structure can be optimized.

[0057] Furthermore, according to an embodiment of the present invention, the lens of the lighting module includes two arc-shaped arms. One arc-shaped arm is connected to a third connecting surface of one side portion, while the other arc-shaped arm is connected to a third connecting surface of the other side portion. The base includes a housing and a base plate connected to each other, with both sides of the housing respectively fitted into the two arc-shaped arms. Through the above structural design, a distance can be provided between the two arc-shaped arms and the base plate to provide some flexibility in the assembly process, effectively compensating for processing errors and improving assembly results, thereby reducing manpower requirements. Therefore, the industrial lighting device can effectively reduce manufacturing costs.

[0058] Furthermore, according to embodiments of the present invention, the base of the lighting module includes a housing and a base plate connected to each other. A cavity is formed between the housing and the base plate, which can be used to accommodate the power module, wires, and other necessary components. Thus, users can place additional components in the cavity according to actual needs. Therefore, the use of industrial lighting devices can be more flexible, and their applications can be more extensive.

[0059] Furthermore, according to an embodiment of the present invention, the base of the lighting module includes a housing and a base plate connected to each other. The surface of the housing has multiple grooves. These grooves effectively increase the heat dissipation area, significantly improving the heat dissipation efficiency of the lighting module. This greatly extends the service life of the industrial lighting device. Additionally, the grooves also provide scratch resistance, making scratches on the housing less noticeable. Therefore, the industrial lighting device better meets the needs of practical applications.

[0060] Furthermore, according to an embodiment of the present invention, the industrial lighting device further includes two side covers and two directional adjustment plates. The two side covers are respectively disposed at both ends of the base, and both ends of the bracket are connected to the two side covers via the two directional adjustment plates. Through the structural design of the directional adjustment plates, the user can appropriately adjust the illumination angle of the industrial lighting device. Therefore, the industrial lighting device can meet the needs of different applications. As can be seen from the above, the high-efficiency industrial lighting device according to the embodiments of the present invention can indeed achieve excellent technical effects.

[0061] Please see Figure 9 and Figure 10 . Figure 9 This is a first schematic diagram showing the usage state of a high-efficiency industrial lighting device according to an embodiment of the present invention. Figure 10 This is a second schematic diagram illustrating the usage state of a high-efficiency industrial lighting device according to an embodiment of the present invention. Figure 9 As shown, both ends of the bracket 13 are connected to the two side covers 12 via two directional adjustment plates 14. Each end of the bracket 13 has multiple directional adjustment holes HX, and each directional adjustment plate 14 also has at least two holes. Therefore, the user can fix the bracket 13 to the two directional adjustment plates 14 using one or more fasteners FX.

[0062] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the high-efficiency industrial lighting device according to this embodiment should still be included within the patent scope of the invention.

[0063] like Figure 10As shown, users can select different direction adjustment holes HX to adjust the angle of the bracket 13, thereby changing the illumination angle of the industrial lighting device 1. Through the structural design of the aforementioned direction adjustment plate 14, users can appropriately adjust the illumination angle of the industrial lighting device 1. Therefore, the industrial lighting device 1 can meet the needs of different applications.

[0064] As described above, the lighting module 11 of the industrial lighting device 1 includes a base 111, a light source plate 112, and a lens 113. The light source plate 112 is disposed on the base 111. The lens 113 is disposed on the base 111 and covers the light source plate 112. The lens 113 includes an optical module 1131, which includes a central portion CP and two side portions LP. The two side portions P are respectively disposed on both sides of the central portion CP, forming an accommodating space between the central portion CP and the two side portions LP. The light source plate 112 is located in the accommodating space and faces the central portion CP. The curvature of the side of the central portion CP adjacent to the light source plate 112 is smaller than the curvature of the other side of the central portion CP. The side portions LP include an incident surface IS, a reflecting surface FS, and an emitting surface ES. The light emitted by the light source plate 112 passes through the incident surface IS, is then reflected by the reflecting surface FS, and then passes through the emitting surface ES. Therefore, the central portion CP can achieve a focusing effect, while the two side portions LP can achieve a reflecting effect. Through the aforementioned composite optical structure and the design of the asymmetrical central portion CP, the light concentration effect of the optical module 1131 can be significantly improved to reduce light loss, allowing the light emitted by the light source board 112 to be uniformly concentrated on the target area. Therefore, the luminous efficacy and brightness of the industrial lighting device 1 can be significantly improved.

[0065] Of course, this embodiment is only for illustrative purposes and is not intended to limit the scope of the invention. Equivalent modifications or alterations made to the high-efficiency industrial lighting device according to this embodiment should still be included within the patent scope of the invention.

[0066] In summary, according to embodiments of the present invention, an industrial lighting device includes at least one lighting module. The lighting module includes a base, a light source plate, and a lens. The light source plate is disposed on the base. The lens is disposed on the base and covers the light source plate. The lens includes an optical module, which includes a central portion and two side portions. The two side portions are respectively disposed on both sides of the central portion, forming an accommodating space between the central portion and the two side portions. The light source plate is located in the accommodating space and faces the central portion. The curvature of the side of the central portion adjacent to the light source plate is smaller than the curvature of the other side of the central portion. The side portions include an incident surface, a reflecting surface, and an emitting surface. Light emitted from the light source plate passes through the incident surface, is reflected by the reflecting surface, and then passes through the emitting surface. Therefore, the central portion achieves a focusing effect, while the two side portions achieve a reflecting effect. Through the above-described composite optical structure and the design of the asymmetrical central portion, the light focusing effect of the optical module can be significantly improved to reduce light loss, allowing the light emitted from the light source plate to be uniformly concentrated on the target area. Therefore, the luminous efficacy and brightness of the industrial lighting device can be significantly improved.

[0067] According to an embodiment of the present invention, the lens of the illumination module includes an optical module, and the side portion of the optical module further includes a first connecting surface, a second connecting surface, and a third connecting surface. The first connecting surface is located between the light-incident surface and the reflective surface and contacts the base. The second connecting surface is located between the light-incident surface and the light-emitting surface and is centrally connected. The third connecting surface is located between the reflective surface and the light-emitting surface. Through the above structural design, the lens can be fixed on the base, so that there is a distance between the central portion of the optical module and the light source board, thereby ensuring that the performance of the above-mentioned composite optical structure can be optimized.

[0068] Furthermore, according to an embodiment of the present invention, the lens of the lighting module includes two arc-shaped arms. One arc-shaped arm is connected to a third connecting surface of one side portion, while the other arc-shaped arm is connected to a third connecting surface of the other side portion. The base includes a housing and a base plate connected to each other, with both sides of the housing respectively fitted into the two arc-shaped arms. Through the above structural design, a distance can be provided between the two arc-shaped arms and the base plate to provide some flexibility in the assembly process, effectively compensating for processing errors and improving assembly results, thereby reducing manpower requirements. Therefore, the industrial lighting device can effectively reduce manufacturing costs.

[0069] Furthermore, according to embodiments of the present invention, the base of the lighting module includes a housing and a base plate connected to each other. A cavity is formed between the housing and the base plate, which can be used to accommodate the power module, wires, and other necessary components. Thus, users can place additional components in the cavity according to actual needs. Therefore, the use of industrial lighting devices can be more flexible, and their applications can be more extensive.

[0070] Furthermore, according to an embodiment of the present invention, the base of the lighting module includes a housing and a base plate connected to each other. The surface of the housing has multiple grooves. These grooves effectively increase the heat dissipation area, significantly improving the heat dissipation efficiency of the lighting module. This greatly extends the service life of the industrial lighting device. Additionally, the grooves also provide scratch resistance, making scratches on the housing less noticeable. Therefore, the industrial lighting device better meets the needs of practical applications.

[0071] Furthermore, according to an embodiment of the present invention, the industrial lighting device further includes two side covers and two directional adjustment plates. The two side covers are respectively disposed at both ends of the base, and both ends of the bracket are connected to the two side covers via the two directional adjustment plates. Through the structural design of the directional adjustment plates, the user can appropriately adjust the illumination angle of the industrial lighting device. Therefore, the industrial lighting device can meet the needs of different applications.
