Description

Field of invention

[0001] The present invention relates to a method for manufacturing industrial lighting devices and in particular to a method for manufacturing jointly usable mold tools for industrial lighting devices. State of the art

[0002] With the development of industry, the demand for industrial lighting equipment (such as high-bay lights, explosion-proof lights, etc.) used in mines, oil fields, and factories is steadily increasing. Some existing industrial lighting equipment uses a separate design, meaning the heat sink and driver are manufactured using different tooling, which significantly increases manufacturing costs. Other existing industrial lighting equipment uses an integrated design, meaning the heat sink and driver are manufactured using the same tooling. However, if the driver fails, the lighting equipment cannot be repaired. The user can only replace the entire lighting unit, which significantly increases repair and maintenance costs.

[0003] From German patent application DE 10 2010 044 770 A1, molds for injection molding or die casting, in particular for the production of plastic articles, are known in which the material is introduced into the mold cavity in a flowable state and hardens. The mold is equipped with a nozzle-side mold plate having a U-shaped frame into which a mold insert can be interchangeably placed, and with an ejector-side mold plate having a U-shaped frame into which a mold insert can be interchangeably placed.

[0004] The German patent application DE 10 2015 114 563 A1 describes a method for manufacturing a microlens for an LED module, in which a lens frame is first produced from a first material that is temperature-stable and light-suppressing, then the lens frame is positioned in a mold, and finally a second material that is temperature-stable and transparent is introduced into the cavity formed by the lens frame and the mold to form a lens structure.

[0005] German patent application DE 10 2021 129 753 A1 deals with semiconductor packages, i.e., encapsulated electronic components with electrical connections extending from the encapsulation and mounted on an electronic peripheral, for example, on a printed circuit board, and methods for manufacturing them. German patent application DE 10 2019 121 012 A1 also describes a method for manufacturing a package.

[0006] The publication DE 10 2013 106 459 A1 describes electronic components and in particular electrothermal cooling devices and methods for their manufacture.

[0007] Product information for existing industrial lighting equipment is contained in the product manual. This manual is typically included in the lighting equipment's packaging. Therefore, if the user accidentally loses the manual, they can only search for product information online or request it from the manufacturer (or distributor), which is extremely inconvenient and detracts from the user experience.

[0008] The application of machine-readable information in the form of barcodes to a surface is known, for example, from the publication DE 20 2021 001 643 U1 and the newspaper article in the Süddeutsche Zeitung of November 30, 2014, “My code, it has three corners - Inventor's prize for developer of the QR symbol”, Christoph Neidhart, Tokyo, which deal with a 3D code and a QR code respectively. Technical solution according to the invention

[0009] According to the present invention, a method for manufacturing industrial lighting devices using a common mold for industrial lighting devices with the features of claim 1 is proposed, comprising the following steps: inserting a metallic material into a mold and performing a die-casting step to produce a semi-finished product, wherein the semi-finished product has a plate section and a box section provided on the plate section; removing the semi-finished product from the mold and performing a cooling step to cool the semi-finished product; performing a separation step to separate the plate section from the box section, wherein the separation step comprises machining; performing a reconditioning step on the plate section and box section to obtain a heat sink and a driver;and performing a combination step to combine the heatsink and the driver.;

[0011] In one embodiment, the method for manufacturing jointly usable mold tools for industrial lighting devices further comprises the following step: attaching a nameplate to the heat sink.

[0012] In one embodiment, the method for manufacturing jointly usable mold tools for industrial lighting devices further comprises the following step: generating a barcode on the nameplate.

[0013] In one embodiment, the barcode is a 1D barcode, 2D barcode, or 3D barcode.

[0014] In one embodiment, the separation step includes punching or numerically controlled tool machining.

[0015] In one embodiment, the reprocessing step comprises one or more of the following processes: drilling, thread cutting and painting.

[0016] According to the invention, the step “performing a reprocessing step on the plate section and box section to obtain a heat sink and a driver” comprises the following steps: forming a driver having a rectangular substrate with multiple mounting holes, an upper shell and a lower shell, wherein the upper shell and the lower shell are arranged on the upper surface and the lower surface of the rectangular substrate, respectively; and forming a heat sink with a central hole and multiple mounting bars arranged around the central hole, wherein the shape of the central hole is adapted to the shape of the rectangular substrate.

[0017] According to the invention, the combination step for combining the heat sink and the driver further comprises the following step: passing the multiple fastening pieces through the multiple fastening holes and inserting them into the multiple fastening rods to fasten the driver and the heat sink to each other, and suspending the driver on the heat sink.

[0018] In one embodiment, the metallic material is an aluminum alloy.

[0019] Based on the above description, the method for manufacturing jointly usable molds for industrial lighting devices according to an embodiment of the present invention may have one or more of the following advantages: (1) In one embodiment of the present invention, the method for manufacturing jointly usable molds can first carry out the die-casting step, in which a semi-finished product with a plate section and a box section is formed using a mold; then the separation step is carried out, in which the plate section is separated from the box section; finally, the combination step is carried out, in which the heat sink is combined with the driver. In this manufacturing method, the heat sink and the driver can be produced using a jointly usable mold for industrial lighting devices; therefore, the manufacturing costs of the industrial lighting devices can be significantly reduced, the product competitiveness of the industrial lighting devices can be improved, and market demand can be better met. (2) In one embodiment of the present invention, in the method for manufacturing jointly usable molds, the die-casting step can be carried out first, in which a semi-finished product with a plate section and a box section is formed using a mold; then the separation step is carried out, in which the plate section is separated from the box section; finally, the combination step is carried out, in which the heat sink is combined with the driver. Therefore, if the driver of the industrial lighting device fails, the user can remove the driver for repair and maintenance or replacement, thus greatly reducing the repair and maintenance costs of the industrial lighting device. Therefore, the industrial lighting device can better meet the requirements of practical applications. (3) In one embodiment of the present invention, a nameplate can be simultaneously arranged on the industrial lighting device during the method for manufacturing jointly usable molds, whereby the overall visual effect of the industrial lighting device's appearance can be improved by the nameplate.

[0020] The detailed features and advantages of the present invention are described in detail below in exemplary embodiments, so that the present invention can be easily implemented by a person skilled in the art according to the description. Based on the content, claims, and drawings disclosed in this description, a person skilled in the art can easily understand the purpose and advantages of this invention. Detailed description of the exemplary implementations

[0021] The exemplary embodiments of the inventive method for manufacturing jointly usable molds for industrial lighting devices are described below with reference to the drawings. For clarity and the purpose of the description, the sizes and proportions of the various components shown in the drawings are not necessarily drawn to scale. When a component is described as "connected" or "coupled" to another component in the following description and / or the claims, it may be directly connected or coupled to the other component, or there may be intermediate components. When a component is described as "directly connected" or "directly coupled" to another component, there are no intermediate components.Other terms used to describe the relationship between components or layers should be interpreted in the same way. For ease of understanding, the same components are designated with the same reference symbols in the following examples.

[0022] It will be directed to the Fig. Reference is made to Figures 1 to 5, which show a first, second, third, fourth, and fifth schematic view of the exemplary embodiment of the inventive method for manufacturing jointly usable molds for industrial lighting devices. The method for manufacturing jointly usable molds according to the present exemplary embodiment can be used to produce industrial lighting devices (e.g., high-bay lights and explosion-proof lights) suitable for hazardous workplaces (e.g., mines, oil fields, and factories). It is referred to Fig. 1. Reference is made to the following. The first step consists of inserting the metallic material into the mold 11 through the feed inlet 111 of the mold 11 and carrying out the die-casting step. In one embodiment, the metallic material can be an aluminum alloy or another available metallic material.

[0023] It will be on Fig. 2. The above die-casting step produces a semi-finished product 12. The second step then consists of removing the semi-finished product 12 from the mold 11 and performing a cooling step to cool the semi-finished product 12. Due to the structure of the mold 11, the semi-finished product 12 can have a plate section 121 and a box section 122, with the box section 122 being located on the plate section 121.

[0024] It will be on Fig. 3. The third step consists of performing a pretreatment step in which the material head X1 and the overflows X2 of the semi-finished product 12 are removed. In one embodiment, the pretreatment step can be carried out by machining, such as punching, numerically controlled tooling, and the like.

[0025] It will be on Fig. 4. The fourth step consists of performing a separation step in which the plate section 121 and the box section 122 of the semi-finished product 12 are separated from each other. In one embodiment, the separation step can also be performed by machining, such as punching, CNC machining, and the like. The fifth step consists of performing a reconditioning step on the plate section 121 and box section 122 to obtain a heat sink 121' and a driver 122'. In one embodiment, the reconditioning step includes one or more of the following processes: drilling, tapping, and painting to form other necessary components such as cooling fins, screw holes, bolts, and mounting plates. The structures of the heat sink 121' and the driver 122' can be varied according to the actual requirements.

[0026] In the present embodiment, the driver 122' can have a rectangular substrate 1221, an upper shell 1222, and a lower shell 1223, wherein the rectangular substrate 1221 can be square, rectangular, or rhomboid, and the upper shell 1222 and the lower shell 1223 are arranged on the upper and lower surfaces of the rectangular substrate 1221, respectively. The rectangular substrate 1221 has several mounting holes FH, each provided at one of the four corners of the rectangular substrate 1221. The heat sink 121' has a central hole CH and several mounting bars PT, the shape of the central hole CH being adapted to the shape of the rectangular substrate 1221. The several mounting bars PT are arranged around the central hole CH, with each mounting bar PT being located adjacent to the midpoint of one side of the central hole CH.

[0027] It will be on Fig. 5. Reference is made to this. The final step consists of performing a combination step in which the heat sink 121' is combined with the driver 122', thus obtaining a module that unites the heat sink 121' and the driver 122'. In the present embodiment, the multiple mounting pieces Fx are inserted through the multiple corresponding mounting holes FH and into the multiple corresponding mounting rods PT to fasten the driver 122' and the heat sink 121' to each other. In this way, the driver 122' can be suspended from the heat sink 121'. Due to the structural design of the heat sink 121' and the driver 122', the heat sink 121' and the driver 122' can be easily recombined to form a module that unites the heat sink 121' and the driver 122' after they have been separated by the separation step.A packaging process can then be carried out to package the module.

[0028] The present embodiment serves only for illustration and is not intended to limit the scope of the present invention. Equivalent modifications or changes made according to the heat sink 121' and the driver 122' of the present embodiment are also within the scope of protection of the present invention.

[0029] As can be seen from the above description, in the method for manufacturing jointly usable molds according to the present embodiment, the die-casting step can first be carried out, in which a semi-finished product 12 with a plate section 121 and a box section 122 is formed using a mold 11. Subsequently, the separation step is carried out, in which the plate section 121 is separated from the box section 122. Finally, the combination step is carried out, in which the heat sink 121' is combined with the driver 122'. With this manufacturing method, the heat sink 121' and the driver 122' can be manufactured for industrial lighting devices using a single, jointly usable mold 11. Therefore, the manufacturing costs of the industrial lighting devices can be effectively reduced, and the product competitiveness of the industrial lighting devices can be improved.In this way, the industrial lighting device produced by the process for manufacturing jointly usable mold tools can better meet market demand.

[0030] Furthermore, if the driver of the industrial lighting device fails, the user can remove the driver 122' for repair, maintenance, or replacement, allowing the industrial lighting device to operate normally. This allows the user convenient and effective repair or maintenance, thus reducing the repair or maintenance costs of the industrial lighting device. Therefore, the industrial lighting device manufactured using the method of producing shared molds can better meet the requirements of practical applications.

[0031] This makes it possible to achieve a situation where the industrial lighting device produced by the method for manufacturing shared molds exhibits the advantages of the prior art without its disadvantages. The desired beneficial effects can indeed be achieved through lower costs with the method for manufacturing shared molds.

[0032] In another embodiment, the industrial lighting device can also be equipped with a nameplate. The overall visual appearance of the industrial lighting device can be enhanced by the nameplate. Furthermore, the nameplate can be provided with a barcode (1D, 2D, or 3D), allowing the user to quickly access product information and other related information about the industrial lighting device by scanning the barcode with an electronic device (such as a smartphone or tablet). Therefore, even if the user has lost the product manual for the industrial lighting device, they can still install it conveniently and quickly.Thus, the structural quality of the industrial lighting device can be greatly improved through this structural design, effectively improving the user experience and increasing user satisfaction.

[0033] The present embodiment serves only for illustration and is not intended to limit the scope of the present invention. Equivalent modifications or changes made according to the method for manufacturing jointly usable molds for industrial lighting devices of the present embodiment are also within the scope of protection of the present invention.

[0034] It will be on Fig. Reference is made to Figure 6, which shows a flowchart of the exemplary embodiment of the inventive method for manufacturing jointly usable molds for industrial lighting devices. As shown in the figure, the method for manufacturing jointly usable molds for industrial lighting devices according to the present exemplary embodiment comprises the following steps: Step S61: Inserting a metallic material into a mold and performing a die-casting step to produce a semi-finished product, wherein the semi-finished product has a plate section and a box section provided on the plate section; Step S62: Removing the semi-finished product from the mold and performing a cooling step to cool the semi-finished product; Step S63: Perform a pretreatment step to remove overflows and the material head of the semi-finished product; Step S64: Perform a separation step to separate the plate section from the box section; Step S65: Performing a reprocessing step on the plate section and box section to obtain a heat sink and a driver; The reprocessing step allows the formation of a driver 122' comprising a rectangular substrate 1221 with multiple mounting holes FH, an upper shell 1222, and a lower shell 1223, wherein the upper shell 1222 and the lower shell 1223 are arranged on the upper and lower surfaces of the rectangular substrate 1221, respectively. The reprocessing step also allows the formation of a heat sink 121' with a central hole CH and multiple mounting bars PT arranged around the central hole CH, wherein the shape of the central hole CH is adapted to the shape of the rectangular substrate 1221; Step S66: Perform a combination step to combine the heat sink and the driver. The combination step allows the multiple mounting pieces Fx to be inserted through the multiple mounting holes FH and into the multiple mounting bars PT to attach the driver 122' and the heat sink 121' to each other, with the driver 122' suspended from the heat sink 121'. In one embodiment, the mounting pieces Fx can be screws, bolts, or other similar components. Subsequently, a packaging procedure can be performed to package the module.

[0035] The present embodiment serves only for illustration and is not intended to limit the scope of the present invention. Equivalent modifications or changes made according to the method for manufacturing jointly usable molds for industrial lighting devices of the present embodiment are also within the scope of protection of the present invention.

[0036] It is worth noting that some existing industrial lighting devices use an integrated design, meaning the heat sink and driver are manufactured using the same mold. However, if the driver fails, the lighting device cannot be repaired. The user can only replace the lighting device with another one, which significantly increases repair and maintenance costs. Furthermore, product information for existing industrial lighting devices is contained in the product manual. This manual is usually included in the lighting device's packaging. Therefore, if the user accidentally loses the manual, they can only search for product information online or request it from the manufacturer (or distributor), which is extremely inconvenient and detracts from the user experience.In contrast, according to one embodiment of the present invention, in the method for manufacturing jointly usable molds, the die-casting step can first be carried out, in which a semi-finished product with a plate section and a box section is formed using a mold; subsequently, the separation step is carried out, in which the plate section is separated from the box section; finally, the combination step is carried out, in which the heat sink is combined with the driver. With this manufacturing method, the heat sink and the driver can be produced using a single, jointly usable mold for industrial lighting devices; therefore, the manufacturing costs of the industrial lighting devices can be significantly reduced, the product competitiveness of the industrial lighting devices can be improved, and market demand can be better met.

[0037] In one embodiment of the present invention, the method for manufacturing jointly usable molds can begin with a die-casting step in which a semi-finished product consisting of a plate section and a box section is formed using a mold. This is followed by a separation step in which the plate section is separated from the box section. Finally, a combination step is performed in which the heat sink is combined with the driver. With this manufacturing method, the heat sink and the driver can be produced using a single, jointly usable mold for industrial lighting devices. Therefore, the manufacturing costs of industrial lighting devices can be significantly reduced, the product competitiveness of industrial lighting devices can be improved, and market demand can be better met.Therefore, if the driver of the industrial lighting device fails, the user can remove the driver for repair, maintenance, or replacement, thus significantly reducing the repair and maintenance costs of the industrial lighting device. This allows the industrial lighting device to better meet the requirements of practical applications.

[0038] Furthermore, in one embodiment of the present invention, a nameplate can be simultaneously arranged on the industrial lighting device during the method for manufacturing jointly usable molds, thereby improving the overall visual appearance of the industrial lighting device. Therefore, the structural quality of the industrial lighting device can be significantly improved by this structural design, effectively enhancing the user experience and simultaneously increasing user satisfaction.

[0039] Furthermore, in an embodiment of the present invention, a nameplate can be simultaneously arranged on the industrial lighting device during the method for manufacturing shared molds. This nameplate can be provided with a barcode (1D barcode, 2D barcode, or 3D barcode), allowing the user to quickly obtain product information and other related information about the industrial lighting device by scanning the barcode with an electronic device (such as a smartphone or tablet computer). Therefore, even if the user has lost the product manual for the industrial lighting device, they can still install it conveniently and quickly. In this way, the user experience and satisfaction can be further improved and increased.

[0040] Furthermore, in one embodiment of the present invention, the method for producing shared molds can simultaneously reduce the manufacturing costs and the repair and maintenance costs of the industrial lighting device. Therefore, the popularity of the industrial lighting device can be effectively increased and its range of applications expanded. It is evident from the above description that excellent technical results can indeed be achieved with the embodiment of the inventive method for producing shared molds for industrial lighting devices.

[0041] It will be directed to the Fig. 7 and Fig. 8 and simultaneously on the Fig. Reference is made to 1 to 5. Fig. Figure 7 shows a flowchart of another embodiment of the inventive method for manufacturing jointly usable mold tools for industrial lighting devices; Fig. Figure 8 shows a schematic view of the other embodiment of the inventive method for manufacturing jointly usable molds for industrial lighting devices. As shown in the figures, the method for manufacturing jointly usable molds for industrial lighting devices according to the present embodiment comprises the following steps: Step S71: Inserting a metallic material into a mold and performing a die-casting step to produce a semi-finished product, wherein the semi-finished product has a plate section and a box section provided on the plate section; Step S72: Removing the semi-finished product from the mold and performing a cooling step to cool the semi-finished product; Step S73: Perform a pretreatment step to remove overflows and the material head of the semi-finished product; Step S74: Perform a separation step to separate the plate section from the box section; Step S75: Performing a reprocessing step on the plate section and box section to obtain a heat sink and a driver; The reprocessing step allows the formation of a driver 122' comprising a rectangular substrate 1221 with multiple mounting holes FH, an upper shell 1222, and a lower shell 1223, wherein the upper shell 1222 and the lower shell 1223 are arranged on the upper and lower surfaces of the rectangular substrate 1221, respectively. The reprocessing step also allows the formation of a heat sink 121' with a central hole CH and multiple mounting bars PT arranged around the central hole CH, wherein the shape of the central hole CH is adapted to the shape of the rectangular substrate 1221; Step S76: Generating a barcode on the nameplate; Step S77: Attaching a nameplate to the heat sink; Step S78: Perform a combination step to combine the heatsink and the driver. The combination step allows the multiple mounting pieces Fx to be inserted through the multiple mounting holes FH and into the multiple mounting bars PT to attach the driver 122' and the heatsink 121' to each other, with the driver 122' suspended from the heatsink 121'.

[0042] The difference from the above embodiment is that in the present embodiment, the method for manufacturing jointly usable molds comprises the step "forming a barcode BD on the nameplate 13" and the step "attaching the nameplate 13 to the heat sink 121'". In one embodiment, the barcode BD can be a 1D barcode, 2D barcode, or 3D barcode. Subsequently, a packaging method can be carried out to package the module.

[0043] The nameplate 13 enhances the overall visual appearance of the industrial lighting device. Therefore, this structural design significantly improves the structural quality of the industrial lighting device, effectively enhancing the user experience and increasing user satisfaction.

[0044] Furthermore, the nameplate 13 can be provided with a barcode (1D barcode, 2D barcode, or 3D barcode) BD, allowing the user to quickly obtain product information and other related information about the industrial lighting device by scanning the barcode BD using an electronic device (such as a smartphone or tablet computer). For example, the user can quickly obtain the product name, product specifications, operating current, operating voltage, operating power, manufacturer, manufacturer's contact information, distributor, distributor's contact information, operating instructions, and precautions for using the industrial lighting device by scanning the barcode BD using an electronic device (such as a smartphone or tablet computer).Therefore, even if the user has lost the product manual for the industrial lighting device, they can still install it conveniently and quickly. This further improves and increases user experience and satisfaction.

[0045] The present embodiment serves only for illustration and is not intended to limit the scope of the present invention. Equivalent modifications or changes made according to the method for manufacturing jointly usable molds for industrial lighting devices of the present embodiment are also within the scope of protection of the present invention.

[0046] Although the steps of the method according to the invention are shown and described in a specific order, the order of the steps can be changed, and certain steps can be carried out in reverse order, or some steps can be carried out simultaneously with other steps. In another embodiment, the various steps can be carried out intermittently and / or alternately.

[0047] It will be on Fig.Reference is made to Figure 9, which shows an exploded view of the industrial lighting device of an embodiment according to the present invention. As shown in the figure, the industrial lighting device LD comprises a suspension ring D1, a heat sink 121', a driver 122', a light source board D2, a lens D3, a waterproof inner ring D4, and a waterproof outer ring D5, wherein the heat sink 121' and the driver 122' are connected to each other, the suspension ring D1 is arranged on the driver 122', the light source board D2 is arranged on the heat sink 121', the lens D3 is also arranged on the heat sink 121' and covers the light source board D2, and the waterproof inner ring D4 and the waterproof outer ring D5 are arranged between the heat sink 121' and the lens D3. The embodiment serves only to illustrate the manufacturing process of the heat sink 121' and the driver 122'.

[0048] The present embodiment serves only for illustration and is not intended to limit the scope of the present invention. Equivalent modifications or changes made according to the industrial lighting device of the present embodiment are also within the scope of protection of the present invention.

[0049] In summary, the method for manufacturing interchangeable molds according to an embodiment of the present invention involves first performing the die-casting step, in which a semi-finished product with a plate section and a box section is formed using a mold; then performing the separation step, in which the plate section is separated from the box section; and finally performing the combination step, in which the heat sink is combined with the driver. With this manufacturing method, the heat sink and the driver can be produced using a single interchangeable mold for industrial lighting devices. Therefore, the manufacturing costs of industrial lighting devices can be significantly reduced, the product competitiveness of industrial lighting devices can be improved, and market demand can be better met.

[0050] Furthermore, in the method for manufacturing jointly usable molds according to an embodiment of the present invention, the die-casting step can be carried out first, in which a semi-finished product with a plate section and a box section is formed using a mold; subsequently, the separation step is carried out, in which the plate section is separated from the box section; finally, the combination step is carried out, in which the heat sink is combined with the driver. Therefore, if the driver of the industrial lighting device fails, the user can remove the driver for repair, maintenance, or replacement, thus significantly reducing the repair and maintenance costs of the industrial lighting device. Consequently, the industrial lighting device can better meet the requirements of practical applications.
