Description

Technical Field

[0001] This invention relates to a method for manufacturing an industrial lighting device, and more particularly to a method for manufacturing a common mold for an industrial lighting device. Background Technology

[0002] With industrial development, the demand for industrial lighting equipment (such as mining lamps and explosion-proof lamps) used in mines, oil fields, and factories is gradually increasing. Some existing industrial lighting equipment uses a separate design, meaning the heat sink and driver need to be manufactured using different molds, significantly increasing manufacturing costs. Other existing industrial lighting equipment uses an integrated design, where the heat sink and driver are manufactured using the same mold. However, if the driver fails, the lighting equipment cannot be repaired. Users must replace it with another lighting equipment, which significantly increases maintenance costs.

[0003] Product information for existing industrial lighting equipment is recorded in the product manual, which is usually placed inside the equipment's packaging. Therefore, if a user accidentally loses this manual, they can only search for product information online or obtain it from the manufacturer (or distributor), which is extremely inconvenient and negatively impacts the user experience. Summary of the Invention

[0004] According to an embodiment of the present invention, a method for manufacturing a common mold for an industrial lighting device is provided, comprising the following steps: placing metal material into a mold for die casting to produce a blank having a plate-shaped portion and a box-shaped portion disposed on the plate-shaped portion; removing the blank from the mold and performing a cooling step to cool the blank; performing a separation step to separate the plate-shaped portion from the box-shaped portion; performing a reprocessing step on the plate-shaped portion and the box-shaped portion to obtain a heat sink and a driver respectively; and performing an assembly step to assemble the heat sink and the driver.

[0006] In one embodiment, the common mold manufacturing method for industrial lighting devices further includes the following steps: fixing a nameplate to a heat sink.

[0007] In one embodiment, the common mold manufacturing method for industrial lighting devices further includes the following steps: forming a barcode on a nameplate.

[0008] In one embodiment, the barcode is a one-dimensional barcode, a two-dimensional barcode, or a three-dimensional barcode.

[0009] In one embodiment, the separation step is machining with a punch or numerical control tool.

[0010] In one embodiment, the reprocessing step includes one or more of drilling, tapping, and spraying.

[0011] In one embodiment, the step of reprocessing the plate-shaped portion and the box-shaped portion to obtain a heat sink and a driver respectively includes: forming a driver including a rectangular substrate having multiple fixing holes, an upper housing and a lower housing, the upper housing and the lower housing being disposed on the upper surface and the lower surface of the rectangular substrate respectively; and forming a heat sink having a central hole and multiple fixing posts disposed around the central hole, the shape of the central hole corresponding to the shape of the rectangular substrate.

[0012] In one embodiment, the assembly step of assembling the heat sink and the driver includes passing multiple fasteners through multiple fastening holes and multiple fastening posts to fix the driver and the heat sink to each other and to suspend the driver on the heat sink.

Therefore, when the driver of the industrial lighting device fails, the user can remove the driver for repair or replacement, which significantly reduces the maintenance cost of the industrial lighting device. Therefore, the industrial lighting device is more likely to meet the needs of practical applications.

[0017] (3) In one embodiment of the present invention, the shared mold manufacturing method can simultaneously install a nameplate on the industrial lighting device, which can enhance the overall visual effect of the industrial lighting device.

[0032] The following description, with reference to the accompanying drawings, illustrates an embodiment of the common mold manufacturing method for industrial lighting devices according to the present invention. For clarity and ease of illustration, the dimensions and proportions of the components in the drawings may be exaggerated or reduced. In the following description and / or claims, when a component is referred to as "connected" or "coupled" to another component, it may be directly connected or coupled to that other component, or an intervening component may be present; while when a component is referred to as "directly connected" or "directly coupled" to another component, no intervening component is present. Other terms used to describe the relationship between components or layers should be interpreted in the same manner. For ease of understanding, the same components in the following embodiments are indicated by the same symbols.

[0033] Please see Figures 1-5 These are first, second, third, fourth, and fifth schematic diagrams illustrating a common mold manufacturing method for industrial lighting devices according to an embodiment of the present invention. The common mold manufacturing method of this embodiment can be used to manufacture industrial lighting devices (such as mining lamps, explosion-proof lamps, etc.) suitable for hazardous workplaces (such as mines, oil fields, factories, etc.). Figure 1 As shown, the first step is to place the metal material into the mold 11 through the feed port 111 and perform a die-casting process. In one embodiment, the metal material may be an aluminum alloy or other existing metal materials.

[0034] like Figure 2 As shown, the aforementioned die-casting process produces a blank 12. Then, the second step involves removing the blank 12 from the mold 11 and performing a cooling step to cool the blank 12. The structure of the mold 11 allows the blank 12 to have a plate-shaped portion 121 and a box-shaped portion 122; the box-shaped portion 122 is disposed on the plate-shaped portion 121.

[0035] like Figure 3 As shown, the third step is a pre-treatment step to remove the slag head X1 and slag bag X2 from the blank 12. In one embodiment, the pre-treatment step can be performed by mechanical processing, such as punching, numerical control machine tool processing, etc.

[0036] like Figure 4 As shown, the fourth step is a separation step to separate the plate-shaped portion 121 and the box-shaped portion 122 of the blank 12. In one embodiment, the separation step can also be performed by machining, such as by punching, numerical control machine tool machining, etc. Then, the fifth step is to reprocess the plate-shaped portion 121 and the box-shaped portion 122 to obtain the heat sink 121' and the driver 122' respectively. In one embodiment, the reprocessing step includes one or more of drilling, tapping, and spraying to form heat sink fins, screw holes, studs, fixing plates, and other necessary components; the structure of the heat sink 121' and the driver 122' can be varied according to actual needs.

[0037] In this embodiment, the driver 122' may have a rectangular substrate 1221, an upper housing 1222, and a lower housing 1223; the rectangular substrate 1221 may be square, rectangular, or rhomboid. The upper housing 1222 and the lower housing 1223 are respectively disposed on the upper and lower surfaces of the rectangular substrate 1221. The rectangular substrate 1221 has a plurality of fixing holes FH, which are respectively disposed at the four corners of the rectangular substrate 1221. The heat sink 121' has a central hole CH and a plurality of fixing posts PT, the shape of the central hole CH corresponding to the shape of the rectangular substrate 1221. The plurality of fixing posts PT are disposed around the central hole CH; wherein, each fixing post PT is disposed at the center point of one of the sides adjacent to the central hole CH.

[0038] like Figure 5 As shown, the final step is a combination step to assemble the heat sink 121' and the driver 122' to obtain a module integrating the heat sink 121' and the driver 122'. In this embodiment, multiple fasteners Fx pass through multiple fastening holes FH and multiple fastening posts PT to fix the driver 122' and the heat sink 121' to each other. Thus, the driver 122' can suspend above the heat sink 121'. The structural design of the heat sink 121' and the driver 122' allows them to be easily reassembled into a module integrating the heat sink 121' and the driver 122' after being separated in the separation step. Then, a packaging process can be performed to package the module.

[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 heat sink 121' and driver 122' according to this embodiment should still be included within the patent scope of the invention.

[0040] As described above, the shared mold manufacturing method of this embodiment first performs a die-casting step to form a blank 12 having a plate-shaped portion 121 and a box-shaped portion 122 through a mold 11, and then performs a separation step to separate the plate-shaped portion 121 and the box-shaped portion 122. Finally, this method performs an assembly step to assemble the heat sink 121' and the driver 122'. The above manufacturing process can manufacture the heat sink 121' and the driver 122' of an industrial lighting device through a shared mold 11. In this way, the manufacturing cost of the industrial lighting device can be effectively reduced, thereby improving the product competitiveness of the industrial lighting device. Therefore, the industrial lighting device manufactured by this shared mold manufacturing method is more in line with market demands.

[0041] Furthermore, when the driver 122' of the industrial lighting device malfunctions, the user can directly remove the driver 122' for repair or replacement, enabling the industrial lighting device to operate normally. This allows users to conveniently and efficiently repair or maintain the device, thus reducing maintenance costs. Therefore, industrial lighting devices manufactured using this shared mold manufacturing method are more likely to meet the needs of practical applications.

[0042] Therefore, industrial lighting devices manufactured using this shared mold manufacturing method possess the advantages of existing technologies without their disadvantages. This shared mold manufacturing method can indeed achieve the desired effect at a lower cost.

[0043] In another embodiment, the industrial lighting device may also have a nameplate, which enhances the overall visual appeal of the device. Furthermore, this nameplate may contain a barcode (such as a repair code, 2D barcode, or 3D barcode), allowing users to quickly obtain product information and other relevant details by scanning the barcode using an electronic device (such as a smartphone or tablet). Therefore, even if the user has lost the product manual, they can easily and quickly install and use the industrial lighting device. Thus, the above structural design significantly improves the quality of the industrial lighting device, effectively enhancing the user experience and increasing user satisfaction.

[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 common mold manufacturing method of the industrial lighting device according to this embodiment should still be included within the patent scope of the invention.

[0045] Please see Figure 6The figure shows a flowchart of a common mold manufacturing method for an industrial lighting device according to an embodiment of the present invention. As shown, the common mold manufacturing method for the industrial lighting device of this embodiment includes the following steps:

[0046] Step S61: The metal material is placed into the mold for die casting to produce a blank, the blank having a plate-shaped portion and a box-shaped portion disposed on the plate-shaped portion.

[0047] Step S62: Remove the blank from the mold and perform a cooling step to cool the blank.

[0048] Step S63: Perform a pretreatment step to remove slag bales and material heads from the blank.

[0049] Step S64: Perform a separation step to separate the plate-shaped portion from the box-shaped portion.

[0050] Step S65: A reprocessing step is performed on the plate-shaped portion and the box-shaped portion to obtain a heat sink and a driver, respectively. The reprocessing step can form a driver 122' with a rectangular substrate 1221 having multiple fixing holes FH, an upper housing 1222, and a lower housing 1223. The upper housing 1222 and the lower housing 1223 are respectively disposed on the upper and lower surfaces of the rectangular substrate 1221. Additionally, the reprocessing step can form a heat sink 121' having a central hole CH and multiple fixing posts PT disposed around the central hole CH. The shape of the central hole CH corresponds to the shape of the rectangular substrate 1221.

[0051] Step S66: Perform the assembly step to assemble the heat sink and the driver. Through the assembly step, multiple fasteners Fx can pass through the multiple fastening holes FH and the multiple fastening posts PT respectively to fix the driver 122' and the heat sink 121' to each other, and to suspend the driver 122' above the heat sink 121'. In one embodiment, the fasteners Fx can be screws, bolts, or other similar components. Then, a packaging process can be performed to package the module.

[0052] 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 common mold manufacturing method of the industrial lighting device according to this embodiment should still be included within the patent scope of the invention.

[0053] It is worth noting that some existing industrial lighting devices employ an integrated design, where the heat sink and driver are manufactured using the same mold. However, if the driver fails, the lighting device cannot be repaired. Users must replace it with another lighting device, significantly increasing maintenance costs. Furthermore, product information for existing industrial lighting devices is recorded in the instruction manual, which is usually included in the device's packaging. Therefore, if a user loses the manual, they must search for product information online or obtain it from the manufacturer (or distributor), which is extremely inconvenient and negatively impacts the user experience. In contrast, according to embodiments of the present invention, the shared mold manufacturing method first performs a die-casting step to form a blank with a plate-like portion and a box-like portion using a single mold, then performs a separation step to separate the plate-like portion from the box-like portion, and finally performs an assembly step to assemble the heat sink and driver. This manufacturing process allows the heat sink and driver of the industrial lighting device to be manufactured using a single mold, thus significantly reducing the manufacturing cost of industrial lighting devices, enhancing their product competitiveness, and better meeting market demands.

[0054] Furthermore, according to embodiments of the present invention, the shared mold manufacturing method can first perform a die-casting step to form a blank having a plate-like portion and a box-like portion through a mold, then perform a separation step to separate the plate-like portion and the box-like portion, and finally perform an assembly step to assemble the heat sink and the driver. Therefore, when the driver of the industrial lighting device fails, the user can remove the driver for repair or replacement, significantly reducing the maintenance cost of the industrial lighting device. Thus, the industrial lighting device is more reliably able to meet the needs of practical applications.

[0055] Furthermore, according to embodiments of the present invention, the shared mold manufacturing method can simultaneously install a nameplate on the industrial lighting device, which can enhance the overall visual appeal of the industrial lighting device. Therefore, the above-described structural design can significantly improve the quality of the industrial lighting device, effectively enhancing the user experience and increasing user satisfaction.

[0056] Furthermore, according to embodiments of the present invention, the shared mold manufacturing method can simultaneously affix a nameplate to the industrial lighting device, and this nameplate can have a barcode (such as a repair code, a two-dimensional barcode, or a three-dimensional barcode). Therefore, users can quickly obtain product information and other relevant information about the industrial lighting device by scanning this barcode using an electronic device (such as a smartphone, tablet computer, etc.). Thus, even if the user loses the product manual for the industrial lighting device, they can still easily and quickly install and use it, thereby further enhancing the user experience and satisfaction.

[0057] Furthermore, according to embodiments of the present invention, the shared mold manufacturing method can simultaneously reduce the manufacturing and maintenance costs of industrial lighting devices, thus effectively increasing the adoption rate of industrial lighting devices. Therefore, the application range of industrial lighting devices can be broadened. As can be seen from the above, the shared mold manufacturing method for industrial lighting devices according to embodiments of the present invention can indeed achieve excellent technical results.

Figure 8 This is a schematic diagram of a common mold manufacturing method for an industrial lighting device according to another embodiment of the present invention. As shown in the figure, the common mold manufacturing method for the industrial lighting device of this embodiment includes the following steps:

[0059] Step S71: The metal material is placed into the mold for die casting to produce a blank, the blank having a plate-shaped portion and a box-shaped portion disposed on the plate-shaped portion.

[0060] Step S72: Remove the blank from the mold and perform a cooling step to cool the blank.

[0061] Step S73: Perform a pretreatment step to remove slag bales and material heads from the blank.

[0062] Step S74: Perform a separation step to separate the plate-shaped portion from the box-shaped portion.

[0063] Step S75: A reprocessing step is performed on the plate-shaped portion and the box-shaped portion to obtain a heat sink and a driver, respectively. This reprocessing step can form a driver 122' with a rectangular substrate 1221 having multiple fixing holes FH, an upper housing 1222, and a lower housing 1223. The upper housing 1222 and the lower housing 1223 are respectively disposed on the upper and lower surfaces of the rectangular substrate 1221. Additionally, the reprocessing step can form a heat sink 121' having a central hole CH and multiple fixing posts PT disposed around the central hole CH. The shape of the central hole CH corresponds to the shape of the rectangular substrate 1221.

[0064] Step S76: Form a barcode on the nameplate.

[0065] Step S77: Attach the nameplate to the heat sink.

[0066] Step S78: Perform the assembly step to assemble the heat sink and the driver. Through the assembly step, multiple fasteners Fx can pass through the multiple fastening holes FH and the multiple fastening posts PT respectively to fix the driver 122' and the heat sink 121' to each other, and to make the driver 122' suspend on the heat sink 121'.

[0067] Unlike the previous embodiments, the common mold manufacturing method in this embodiment includes the steps of forming a barcode BD on the nameplate 13 and fixing the nameplate 13 to the heat sink 121'. In one embodiment, the barcode BD can be a one-dimensional barcode, a two-dimensional barcode, or a three-dimensional barcode. Then, a packaging process can be performed to package the module.

[0068] This nameplate 13 enhances the overall visual appeal of the industrial lighting fixture. Therefore, the aforementioned structural design significantly improves the perceived quality of the industrial lighting fixture, effectively enhancing the user experience and increasing user satisfaction.

[0069] Furthermore, this nameplate 13 can have a barcode BD (such as a repair code, two-dimensional barcode, or three-dimensional barcode), so users can quickly obtain product information and other relevant information about the industrial lighting device by scanning this barcode BD using electronic devices (such as smartphones, tablets, etc.). For example, users can quickly obtain the product name, specifications, operating current, operating voltage, operating power, manufacturer, manufacturer contact information, distributor, distributor contact information, instruction manual, and usage precautions by scanning this barcode BD. Therefore, even if the user has lost the product manual, they can still easily and quickly install and use the industrial lighting device, thus further improving the user experience and satisfaction.

[0070] 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 common mold manufacturing method of the industrial lighting device according to this embodiment should still be included within the patent scope of the invention.

[0071] Although the steps of the methods described in this invention are shown and described in a specific order, the order of operation of each method may be changed, some steps may be performed in reverse order, or some steps may be performed simultaneously with other steps. In another embodiment, different steps may be implemented intermittently and / or alternately.

[0072] Please see Figure 9This is an exploded view of the structure of an industrial lighting device according to an embodiment of the present invention. As shown, the industrial lighting device LD includes a hanging ring D1, a heat sink 121', a driver 122', a light source plate D2, a lens D3, an inner waterproof ring D4, and an outer waterproof ring D5. The heat sink 121' and the driver 122' are coupled together. The hanging ring D1 is disposed on the driver 122'.

[0073] 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 industrial lighting device according to this embodiment should still be included within the patent scope of the invention.
