Description

[Technical Field]

[0001] The present invention relates to a lighting device, and more particularly to a linear lighting device having a one-sided fixed structure. [Background technology]

[0002] The inverted Fuji (mountain) lighting fixture has a unique shape and lighting characteristics, and its main feature is the design of a triangular base or an inverted cone base. This design is advantageous for uniform light distribution and efficient space utilization, so it is widely used in various buildings.

[0003] However, the conventional inverted Fuji lighting device still has many drawbacks that need to be improved. For example, the optical structure of the conventional inverted Fuji lighting device causes a portion of the light generated by the light source board to be lost, which significantly reduces the light efficiency of the lighting device.

[0004] Furthermore, the globe and base of the conventional inverted Fuji type lighting device must have a fixed structure, which makes the globe and base structures complicated and prone to damage during transportation.

[0005] Furthermore, the installation process of the conventional inverted Fuji-type lighting device is relatively complicated and requires a lot of labor, resulting in increased labor costs. Summary of the Invention [Problem to be solved by the invention]

[0006] SUMMARY OF THE INVENTION An object of the present invention is to provide a linear lighting device with a one-sided fixed structure. [Means for solving the problem]

[0007] According to one embodiment of the present invention, there is provided a linear lighting device having a one-sided fixing structure comprising a tubular globe, a support plate, a light source substrate, a base, and a clip. The tubular globe has a light-emitting portion and a light-shielding portion. The light-emitting portion has a curved light-emitting surface. The bottom of the light-emitting portion has a lower opening, and the top of the light-shielding portion has an upper opening, which are respectively installed in two grooves on both sides. The bottom of the light-emitting portion is connected to the upper part of the light-shielding portion, and the width of the bottom of the light-emitting portion is greater than the width of the upper part of the light-shielding portion. The support plate is installed within the light-shielding portion and adjacent to the upper opening. The light source substrate is installed on one side of the support plate and faces the light-emitting portion. The base has a central groove, and the tubular globe is installed in the central groove and closes it. The clip is U-shaped and includes a bottom plate, two side walls, and two protrusions. The bottom plate is fixed to the bottom of the central groove, and the two protrusions are installed on the two side walls, respectively. The two protrusions are respectively embedded in the two grooves to fix the clip and the light blocking part together.

[0008] In one embodiment, the width of the bottom of the light emitting portion is greater than the width of the top of the light blocking portion.

[0009] In one embodiment, the tubular glove is formed from plastic.

[0010] In one embodiment, the light-blocking portion is positioned within the central groove, and the light-blocking portion is exposed to the central groove.

[0011] In one embodiment, the bottom of the central groove has a mounting hole, which has a keyhole shape.

[0012] In one embodiment, the linear lighting device further comprises a power supply module, which is disposed on the other side of the support plate, located within the light blocking portion, and electrically connected to the light source board.

[0013] In one embodiment, each end of the base has a knock-down hole.

[0014] In one embodiment, the linear lighting device further comprises two end caps and two safety ropes, which are respectively installed at opposite ends of the tubular globe and connected to opposite ends of the base via the two safety ropes.

[0015] In one embodiment, each of the end caps has a fixed structure, and each safety rope includes a rope body and a ball head connected to one end of the rope body, the ball head being fixed to the fixed structure, and the other end of the rope body being fixed to one of the ends of the base.

[0016] In one embodiment, the fixing structure includes a protruding post and a fixing hook. One end of the fixing hook is fixed to the bottom of the end cap, and the other end of the fixing hook and the bottom of the end cap are spaced apart to form an entrance. The protruding post is fixed to the bottom of the end cap and is located on one side of the entrance. The rope body passes through a central hole in the fixing hook, and the ball head is positioned relative to the protruding post and the fixing hook. [Effects of the Invention]

[0017] Based on the above, a linear lighting device with a one-sided fixed structure 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, a linear lighting device includes a tubular globe, a support plate, a light source substrate, a base, and a clip. The tubular globe has a light-emitting portion and a light-shielding portion. The light-emitting surface of the light-emitting portion is curved. The bottom of the light-emitting portion has a lower opening, and the top of the light-shielding portion has an upper opening, which are respectively installed in two grooves on both sides. The bottom of the light-emitting portion is connected to the upper part of the light-shielding portion, and the width of the bottom of the light-emitting portion is greater than the width of the top of the light-shielding portion. The support plate is installed within the light-shielding portion and adjacent to the upper opening. The light source substrate is installed on one side of the support plate and faces the light-emitting portion. The base has a central groove, and the tubular globe is installed in the central groove and closes it. The clip is U-shaped and includes a bottom plate, two side walls, and two protrusions. The bottom plate is fixed to the bottom of the central groove, and the two protrusions are installed on the two side walls, respectively. The two protrusions are respectively embedded in the two grooves, fixing the clip and the light shielding part to each other. The one-sided fixing structure allows the tubular globe to be fixed to the substrate without the need for a fixing structure, further simplifying the structure of the tubular globe. Furthermore, the multiple clips are exposed in the central groove, further simplifying the structure of the base. The above structural design makes the linear lighting device more convenient to transport and less susceptible to damage during transportation. (2) In one embodiment of the present invention, the width of the bottom of the light-emitting portion of the tubular globe of the linear lighting device is greater than the width of the top of the light-shielding portion. Because the width of the bottom of the light-emitting portion is greater than the width of the top of the light-shielding portion, most of the light emitted by the light source substrate can pass through the light-emitting portion without being blocked by the light-shielding portion. This optical structure design effectively reduces the light loss of the light source substrate and significantly improves the light efficiency of the linear lighting device. (3) In one embodiment of the present invention, the light source substrate and electronic components of the linear lighting device, such as the power module, are both mounted within a tubular globe. The tubular globe is made of plastic, allowing the tubular globe to have an all-plastic structure. This all-plastic structure effectively prevents reverse voltage generation, improving safety and significantly improving the safety of the linear lighting device. (4) In one embodiment of the present invention, the power supply module of the linear lighting device is installed in the tubular globe, and the power supply module is not installed in the power supply case, but is simply covered with a plastic film. The above-mentioned built-in power supply module design not only effectively prevents reverse voltage generation and improves safety, but also greatly simplifies the structure of the linear lighting device. (5) In one embodiment of the present invention, the light source substrate of the linear lighting device is mounted on a support plate, which may be made of a highly thermally conductive material (such as copper, iron, aluminum, stainless steel, or other metals) and is mounted within the tubular globe. Therefore, the support plate not only provides heat dissipation, but also provides support and increases the structural strength of the tubular globe. Furthermore, the light source substrate is coated with a light-reflective coating to enhance light efficiency. This effectively extends the service life of the linear lighting device, further improving light efficiency and meeting the requirements of practical applications. (6) In one embodiment of the present invention, the linear lighting device further includes two end caps and two safety ropes. The two end caps are respectively installed at both ends of the tubular globe and connected to both ends of the base via the two safety ropes. Each end cap has a fixing structure. Each safety rope includes a rope body and a ball head connected to one end of the rope body. The ball head is fixed to the fixing structure, and the other end of the rope body is fixed to one of the ends of the base. The fixing structure includes a protruding post and a fixing hook. One end of the fixing hook is fixed to the bottom of the end cap, and the other end of the fixing hook is spaced apart from the bottom of the end cap to form an entrance. The protruding post is fixed to the bottom of the end cap and located on one side of the entrance. The rope body passes through a central hole in the fixing hook, allowing the ball head to regulate the position of the protruding post and the fixing hook. The design of the fixing structure allows the two end caps to be stably and quickly connected to both ends of the base via the two safety ropes, preventing the tubular globe from falling. In addition, users can temporarily suspend the tubular globe from the base using the two safety ropes to perform wiring work, which greatly simplifies the installation process of the linear lighting fixture and reduces labor costs, while further improving the safety of the linear lighting device.

DETAILED DESCRIPTION OF THE INVENTION

[0019] In the following embodiments, detailed features and advantages of the present invention are described, the contents of which are sufficient to enable those skilled in the art to understand the technical contents of the present invention and implement them accordingly, and the disclosure contents, claims and drawings of this specification allow those skilled in the art to easily understand the objectives and advantages of the present invention.

[0020] Hereinafter, embodiments of a linear lighting device having a one-sided fixed structure of the present invention will be described with reference to the associated drawings. However, for clarity and ease of description in the drawings, the dimensions and proportions of each component in the drawings may be exaggerated or reduced. In the following description and / or claims, when a component is described as being "connected" or "coupled" to another component, this may be directly connected or coupled to the other component, or an intervening component may be present. When a component is described as being "directly connected" or "directly coupled" to another component, this does not mean that an intervening component is present, and other terms describing the relationship between components or layers should be interpreted similarly. For ease of understanding, the same components in the following embodiments will be denoted and described with the same reference numerals.

[0021] Please refer to Figures 1, 2, and 3. Figure 1 is a perspective view of a linear lighting device having a one-sided fixed structure according to a first embodiment of the present invention. Figure 2 is a first cross-sectional view of a linear lighting device having a one-sided fixed structure according to the first embodiment of the present invention (without a support plate, light source substrate, or power supply module). Figure 3 is a second cross-sectional view of a linear lighting device having a one-sided fixed structure according to the first embodiment of the present invention (with a support plate, light source substrate, and power supply module). Figure 4 is a third cross-sectional view of a linear lighting device having a one-sided fixed structure according to the first embodiment of the present invention. As shown in the figures, the linear lighting device 1 comprises a tubular globe 11, a light source substrate 12, a support plate 13, a power supply module 14, and two end caps 15.

[0022] The tubular globe 11 has a light-emitting portion 111 and a light-shielding portion 112. The two end caps 15 are respectively installed at both ends of the tubular globe 11. In this embodiment, the tubular globe 11 is an all-plastic structure made of plastic (which may be any conventional plastic material, such as PMMA or PC, but is not limited to these). The light-emitting surface LS of the light-emitting portion 111 is curved. The bottom of the light-emitting portion 111 has a lower opening, and the top of the light-shielding portion 112 has an upper opening. The light-shielding portion 112 has two grooves Rs installed on both sides thereof. The bottom of the light-emitting portion 111 is connected to the upper part of the light-shielding portion 112. In addition, the width L1 of the bottom of the light-emitting portion 111 is greater than the width L2 of the top of the light-shielding portion 112. The all-plastic structure described above effectively prevents reverse voltage from occurring, significantly improving the safety of the linear lighting device 1.

[0023] The support plate 13 is installed within the light-shielding portion 112 and adjacent to the upper opening. The cross section of the support plate 13 is U-shaped, and both sides of the support plate 13 are fixed to two inner walls of the light-shielding portion 112, respectively. Each inner wall has an L-shaped hook portion V1 and a positioning plate V2. The positioning plate V2 is installed above the L-shaped hook portion V1. Two L-shaped hook portions V1 are embedded on both sides of the support plate 13, respectively. The two positioning plates V2 provide a positioning function and prevent the support plate 13 from detaching from the two L-shaped hook portions V1. The support plate 13 may be made of a material with high thermal conductivity. This material may be various metals such as copper, iron, aluminum, and stainless steel. Therefore, the support plate 13 not only provides a heat dissipation effect, but also achieves a support function and increases the structural strength of the tubular globe 11.

[0024] The light source substrate 12 is installed on one side of the support plate 13 and faces the light emitting portion 111. The light source substrate 12 may include a circuit board 121 and a plurality of light sources 122, and the plurality of light sources 122 are installed on the circuit board 121. In this embodiment, the plurality of light sources 122 may be light emitting diodes (LEDs). In another embodiment, the light source substrate 12 may be replaced with other light emitting units (such as fluorescent lamps or light bulbs). The light source substrate 12 may further have a light reflective paint on it to provide a light reflective effect and improve light efficiency.

[0025] The power supply module 14 is installed on the other side of the support plate 13 and is located within the light shielding portion 112. The power supply module 14 is electrically connected to the light source substrate 12 and can be installed directly in the light shielding portion 112, eliminating the need for a separate power supply case. Alternatively, the power supply module 14 may simply be covered with a plastic film. In one embodiment, the power supply module 14 is a light-emitting diode driver. In another embodiment, the power supply module 14 may be a driver for other conventional light sources. The above-described design of the built-in power supply module 14 not only improves the safety of the linear lighting device 1, but also greatly simplifies the structure of the linear lighting device 1.

[0026] As a result, the width L1 of the bottom of the light-emitting portion 111 is greater than the width L2 of the top of the light-shielding portion 112, so most of the light emitted by the light source plate 12 can pass through the light-emitting portion 111 and is not blocked by the light-shielding portion 112. The above-mentioned optical structure design effectively reduces the light loss of the light source substrate 12 and greatly improves the light efficiency of the linear lighting device 1.

[0027] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the linear lighting device with one-sided fixed structure of this embodiment should still fall within the protection scope of the present invention.

[0028] Please refer to Figures 5, 6, 7, 8, and 9, and also to Figures 1 to 4. Figure 5 is a perspective view of a linear lighting device having a one-sided fixed structure according to a second embodiment of the present invention. Figure 6 is an exploded view of a linear lighting device having a one-sided fixed structure according to the second embodiment of the present invention. Figure 7 is a side view of the base of a linear lighting device having a one-sided fixed structure according to the second embodiment of the present invention. Figure 8 is an explanatory diagram of the combination of the base and tubular globe of a linear lighting device having a one-sided fixed structure according to the second embodiment of the present invention. Figure 9 is an explanatory diagram of electrical connection wires of a linear lighting device having a one-sided fixed structure according to the second embodiment of the present invention. As shown in the figures, a linear lighting device 1 includes a tubular globe 11, a light source substrate 12, a support plate 13, a power supply module 14, and two end covers 15.

[0029] The above components are the same as those in the previous embodiment. The difference from the previous embodiment is that in this embodiment, the linear lighting device 1 further includes a base 16, two clips 17, and two safety ropes 18.

[0030] The base 16 has a central groove Cs. The tubular globe 11 is installed in the central groove Cs to close the central groove Cs, positioning the light-shielding portion 112 within the central groove Cs and exposing the light-emitting portion 111 through the central groove Cs. The base 16 may also have knock-down holes Bs at both ends. When connecting multiple linear lighting devices 1 in series, the covers of the knock-down holes Bs can be removed. Electrical connecting wires can then pass through the knock-down holes Bs to electrically connect the multiple linear lighting devices 1.

[0031] The two clips 17 may be made of metal, such as copper, iron, aluminum, or stainless steel. Each clip 17 is U-shaped and includes a bottom plate 171, two side walls 172, and two protrusions 173. The bottom plate 171 is fixed to the bottom of the central groove Cs, and the two protrusions 173 are respectively installed on the two side walls 172. Each clip 17 is not exposed to the central groove Cs. As described above, the light-shielding portion 112 has two grooves Rs installed on both sides of the light-shielding portion 112, and the two protrusions 173 are inserted into the two grooves Rs, respectively, to secure the clip 17 and the light-shielding portion 112 to each other. In this way, the tubular globe 11 is fixed to the base 16 via the two clips 17. The number of clips 17 can be adjusted according to actual needs. In another embodiment, the linear lighting device 1 may include only one clip 17 or three or more clips 17. The one-sided locking structure described above allows the tubular globe 11 to be fixed to the base 16 without the need for a fixing structure, simplifying the structure of the tubular globe 11. Furthermore, the clips 17 are not exposed in the central groove Cs, further simplifying the structure of the base 16. The above structural design makes the linear lighting device 1 more convenient to transport and less susceptible to damage during transportation.

[0032] The two end caps 15 are provided at both ends of the tubular globe 11, respectively, and are connected to both ends of the base 16 via the two safety ropes 18. The two end caps 15 achieve waterproof and dustproof effects, thereby improving the safety and service life of the linear lighting device 1.

[0033] The linear lighting device 1 further includes an electrical connection line 19 and a connection terminal 20. The power supply module 14 is connected to the electrical connection line 19, which passes through a connection hole and then connects to the connection terminal 20. The connection hole is located near one end cap 15. A seal ring SR (e.g., a rubber ring) can be installed in this connection hole to achieve waterproof and dustproof effects. The connection terminal 20 can be located on the back side of the tubular globe 11. In this embodiment, the electrical connection line 19 can be fixed to the back side of the tubular globe 11 by tape TP or other similar methods, but is not limited to this.

[0034] As a result, the width of the bottom of the light-emitting portion 111 is greater than the width of the top of the light-shielding portion 112, so most of the light emitted by the light source plate 12 can pass through the light-emitting portion 111 and is not blocked by the light-shielding portion 112. The above-mentioned optical structure design can effectively reduce the light loss of the light source substrate 12 and greatly improve the light efficiency of the linear lighting device 1.

[0035] The linear lighting device 1 includes electronic components such as a light source board 12 and a power supply module 14, which are mounted within the tubular globe 11. The tubular globe 11 may be made of plastic, making the tubular globe 11 an all-plastic structure. This all-plastic structure effectively prevents reverse voltage from occurring, significantly improving the safety of the linear lighting device 1.

[0036] In addition, the power supply module 14 of the linear lighting device 1 can be installed inside the tubular globe 11, not inside a power supply case, but simply covered with a plastic film. The above-mentioned built-in power supply module design not only effectively prevents reverse voltage generation and improves safety, but also greatly simplifies the structure of the linear lighting device 1.

[0037] Furthermore, the one-sided fixing structure described above allows the tubular globe 11 to be fixed to the base 16 without the need for a fixing structure, simplifying the structure of the tubular globe 11. In addition, the clips 17 are not exposed in the central groove Cs, further simplifying the structure of the base 16. The above structural design makes the linear lighting device 1 more convenient to transport and less susceptible to damage during transportation.

[0038] The light source substrate 12 of the linear lighting device 1 is mounted on a support plate 13, which may be made of a highly thermally conductive material (such as copper, iron, aluminum, stainless steel, or other metals) and is mounted within the tubular globe 11. Therefore, the support plate 13 not only provides heat dissipation, but also provides support and enhances the structural strength of the tubular globe 11. The light source substrate 12 also has a light-reflective coating to enhance light efficiency. This effectively extends the service life of the linear lighting device 1 and further improves light efficiency, meeting the requirements of practical applications.

[0039] In this way, the linear lighting device 1 is suitable for application to an inverted Fuji (mountain) type lighting device and achieves high performance. The linear lighting device 1 can also be applied to various other conventional lighting devices.

[0040] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the linear lighting device with one-sided fixed structure of this embodiment should still fall within the protection scope of the present invention.

[0041] However, conventional inverted-mounted lighting devices still have many drawbacks that need to be improved. For example, the optical structure of conventional inverted-mounted lighting devices results in the loss of a portion of the light generated by the light source board, significantly reducing the lighting efficiency of the lighting device. Furthermore, the globe and base of conventional inverted-mounted lighting devices require fixed structures, which makes the globe and base structures complex and prone to damage during transportation. Furthermore, the installation process of conventional inverted-mounted lighting devices is relatively complicated, requiring a lot of labor and increasing labor costs. In contrast, according to an embodiment of the present invention, a linear lighting device includes a tubular globe, a support plate, a light source board, a base, and a clip. The tubular globe has a light-emitting portion and a light-shielding portion. The light-emitting portion has a curved light-emitting surface. The bottom of the light-emitting portion has a lower opening, and the top of the light-shielding portion has an upper opening, which are respectively installed in two grooves on both sides. The bottom of the light-emitting portion is connected to the upper part of the light-shielding portion, and the width of the bottom of the light-emitting portion is greater than the width of the upper part of the light-shielding portion. The support plate is installed within the light-shielding portion and adjacent to the upper opening. The light source substrate is installed on one side of the support plate and faces the light-emitting portion. The base has a central groove, and the tubular globe is installed in the central groove and covers it. The clip is U-shaped and includes a bottom plate, two side walls, and two protrusions. The bottom plate is fixed to the bottom of the central groove, and the two protrusions are installed on the two side walls, respectively. The two protrusions are embedded in the two grooves, respectively, to secure the clip and the light-shielding portion to each other. The one-sided fixing structure allows the tubular globe to be fixed to the base without the need for a fixing structure, further simplifying the tubular globe structure. In addition, the multiple clips are exposed in the central groove, further simplifying the base structure. The above structural design makes the linear lighting device more convenient to transport and less susceptible to damage during transportation.

[0042] In addition, according to an embodiment of the present invention, the width of the bottom of the light-emitting portion of the tubular globe of the linear lighting device is greater than the width of the top of the shading portion. Because the width of the bottom of the light-emitting portion is greater than the width of the top of the shading portion, most of the light emitted by the light source substrate can pass through the light-emitting portion without being blocked by the shading portion. The above optical structure design effectively reduces the light loss of the light source substrate and greatly improves the light efficiency of the linear lighting device.

[0043] In addition, according to an embodiment of the present invention, the light source substrate and electronic components of the linear lighting device, such as the power module, are both mounted within a tubular globe. The tubular globe is made of plastic, allowing the tubular globe to have an all-plastic structure. This all-plastic structure effectively prevents reverse voltage generation, improving safety and significantly improving the safety of the linear lighting device.

[0044] In addition, according to an embodiment of the present invention, the power supply module of the linear lighting device is installed in the tubular globe, and the power supply module is not installed in a power supply case, but is only covered with a plastic film. The above-mentioned built-in power supply module design not only effectively prevents reverse voltage generation and improves safety, but also greatly simplifies the structure of the linear lighting device.

[0045] Furthermore, according to an embodiment of the present invention, the light source substrate of the linear lighting device is mounted on a support plate, which may be made of a highly thermally conductive material (such as copper, iron, aluminum, stainless steel, or other metals) and is mounted within the tubular globe. Therefore, the support plate not only provides heat dissipation, but also provides support and increases the structural strength of the tubular globe. Furthermore, the light source substrate may further include a light-reflective coating to enhance light efficiency. This effectively extends the service life of the linear lighting device, further improves light efficiency, and meets the requirements of practical applications. From the above, it can be seen that the linear lighting device with a one-sided fixed structure according to an embodiment of the present invention can indeed achieve excellent technical effects.

[0046] Please refer to Figures 10, 11, and 12, and also to Figures 1 to 9. Figure 10 is a first explanatory view of the installation process of a linear lighting device having a one-sided fixed structure according to a second embodiment of the present invention. Figure 11 is a first partial enlarged view of area K1 in Figure 10. Figure 12 is a second partial enlarged view of area K1 in Figure 10. As shown in Figure 10, the base 16 further has a mounting hole Gs at the bottom of the central groove Cs, and the mounting hole Gs may be shaped like a keyhole.

[0047] As shown in Figure 11, a user can first secure a fixing member FX (a screw, nail, or other similar member) to the ceiling. Then, the user places the base 16 on the ceiling, aligns the mounting hole Gs with the fixing member FX, and inserts the head of the fixing member into one end of the mounting hole Gs. Then, the user can push the base 16 to move it in a direction toward the other end of the mounting hole Gs (arrow A1 in the figure).

[0048] 12, the base 16 moves toward the other end of the mounting hole Gs, causing the head of the fixing member FX to enter the other end of the mounting hole Gs. In this way, the user can fix the base 16 to the ceiling via the fixing member 16, and fix both ends of the base 16 to the ceiling via other fixing members FX.

[0049] Without the mounting holes Gs, the user must first fix one end of the base 16 to the ceiling, but then the other end of the base 16 must be held by another installer, making installation extremely inconvenient. With the mounting holes Gs, the user can temporarily fix the base 16 to the ceiling and then fix both ends of the base 16, making the installation process more convenient and labor-saving.

[0050] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the linear lighting device with one-sided fixed structure of this embodiment should still fall within the protection scope of the present invention.

[0051] Please refer to Figures 13, 14, 15, and 16, and also to Figures 1 to 12. Figure 13 is a second explanatory view of the installation process of a linear lighting device having a one-sided fixed structure according to a second embodiment of the present invention. Figure 14 is a first partial enlarged view of area K2 in Figure 13. Figure 15 is a second partial enlarged view of area K2 in Figure 13. Figure 16 is a third partial enlarged view of area K2 in Figure 13. As shown in Figure 13, after fixing the base 16 to the ceiling, the user can temporarily suspend the tubular globe 11 from the base 16 via two safety ropes 18 and perform wiring work.

[0052] 14, each safety rope 18 includes a rope body 181 and a ball head 182 connected to one end of the rope body 181. Each end cap 15 has a fixing structure including a protruding post 151 and a fixing hook 152. One end of the fixing hook 152 is fixed to the bottom of the end cap 15, and the other end of the fixing hook 152 is spaced from the bottom of the end cap 15 to form an entrance Es. The protruding post 151 is fixed to the bottom of the end cap 15 and is located on one side of the entrance Es.

[0053] The user can move the ball head 182 in the direction toward the space between the protruding post 151 and the fixed hook 152 (arrow A2 in the figure).

[0054] 15, the user moves the ball head 182 in a direction toward the space between the convex post 151 and the fixed hook 152, and causes one end of the rope body 181 closer to the ball head 182 to enter the space between the convex post 151 and the fixed hook 152. Thereafter, the user pulls the rope body 181 toward the entrance Es (arrow A3 in the figure), thereby causing the rope body 181 to enter the central hole of the fixed hook 152 through the entrance Es.

[0055] 16 , the rope body 181 can pass through the central hole of the fixed hook 152 after passing through the entrance Es and entering the central hole of the fixed hook 152. In this way, the position of the ball head 182 can be restricted by the protruding post 151 and the fixed hook 152. In this way, the ball head 182 can be fixed to a fixed structure, and the other end of the rope body 181 is fixed to one of the ends of the base 16.

[0056] The design of the fixing structure allows the two end caps 15 to be stably and quickly connected to both ends of the base 16 via the two safety ropes 18. The user can temporarily hang the tubular globe 11 on the base 16 via the two safety ropes 18 and perform wiring work. This greatly simplifies the installation process of the linear lighting device 1 and reduces labor costs.

[0057] Furthermore, since the fixing structure is installed on the two end caps 15 rather than on the tubular globe 11, the structure of the tubular globe 11 can be further simplified.

[0058] After the installation process is completed, the two safety ropes 18 can also prevent the tubular globe 11 from falling, thereby further improving the safety of the linear lighting device 1.

[0059] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the linear lighting device with one-sided fixed structure of this embodiment should still fall within the protection scope of the present invention.

[0060] Please refer to Figures 17 and 18. This is a perspective view of a linear lighting device having a one-sided fixed structure according to a third embodiment of the present invention. Figure 18 is a perspective view of a linear lighting device having a one-sided fixed structure according to a fourth embodiment of the present invention. As shown in the figures, the tubular globe 11 can be combined with different bases (base 16 shown in Figure 5, base 16' shown in Figure 17, and base 16'' shown in Figure 18), allowing the linear lighting device 1 to have different appearances and functions.

[0061] Therefore, the tubular globe 11 can be sold separately as an independent product, which allows for more flexible use. At the same time, the above structural design can effectively reduce inventory, thereby reducing costs.

[0062] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the linear lighting device with one-sided fixed structure of this embodiment should still fall within the protection scope of the present invention.

[0063] In summary, according to an embodiment of the present invention, a linear lighting device includes a tubular globe, a support plate, a light source substrate, a base, and a clip. The tubular globe has a light-emitting portion and a light-shielding portion. The light-emitting portion has a curved light-emitting surface. The bottom of the light-emitting portion has a lower opening, and the top of the light-shielding portion has an upper opening, which are respectively installed in two grooves on either side of the lower opening. The bottom of the light-emitting portion is connected to the upper part of the light-shielding portion, and the width of the bottom of the light-emitting portion is greater than the width of the upper part of the light-shielding portion. The support plate is installed within the light-shielding portion and adjacent to the upper opening. The light source substrate is installed on one side of the support plate and faces the light-emitting portion. The base has a central groove, and the tubular globe is installed in the central groove and closes it. The clip is U-shaped and includes a bottom plate, two side walls, and two protrusions. The bottom plate is fixed to the bottom of the central groove, and the two protrusions are installed on the two side walls, respectively. The two protrusions are respectively embedded in the two grooves, fixing the clip and the light shielding part to each other. The one-sided fixing structure allows the tubular globe to be fixed to the substrate without the need for a fixing structure, further simplifying the structure of the tubular globe. Furthermore, the multiple clips are exposed in the central groove, further simplifying the structure of the base. The above structural design makes the linear lighting device more convenient to transport and less susceptible to damage during transportation.

[0064] In addition, according to an embodiment of the present invention, the width of the bottom of the light-emitting portion of the tubular globe of the linear lighting device is greater than the width of the top of the shading portion. Because the width of the bottom of the light-emitting portion is greater than the width of the top of the shading portion, most of the light emitted by the light source substrate can pass through the light-emitting portion without being blocked by the shading portion. The above optical structure design effectively reduces the light loss of the light source substrate and greatly improves the light efficiency of the linear lighting device.

[0065] In addition, according to an embodiment of the present invention, the light source substrate and electronic components of the linear lighting device, such as the power module, are both mounted within a tubular globe. The tubular globe is made of plastic, allowing the tubular globe to have an all-plastic structure. This all-plastic structure effectively prevents reverse voltage generation, improving safety and significantly improving the safety of the linear lighting device.

[0066] In addition, according to an embodiment of the present invention, the power supply module of the linear lighting device is installed in the tubular globe, and the power supply module is not installed in a power supply case, but is only covered with a plastic film. The above-mentioned built-in power supply module design not only effectively prevents reverse voltage generation and improves safety, but also greatly simplifies the structure of the linear lighting device.

[0067] Furthermore, according to an embodiment of the present invention, the light source substrate of the linear lighting device is mounted on a support plate, which may be made of a highly thermally conductive material (such as copper, iron, aluminum, stainless steel, or other metals) and is mounted within the tubular globe. Therefore, the support plate not only provides heat dissipation, but also provides support and increases the structural strength of the tubular globe. Furthermore, the light source substrate may further include a light-reflective coating to enhance light efficiency. This effectively extends the service life of the linear lighting device, further improves light efficiency, and meets the requirements of practical applications.

[0068] Furthermore, according to an embodiment of the present invention, the linear lighting device further includes two end caps and two safety ropes. The two end caps are respectively installed at both ends of the tubular globe and connected to both ends of the base via the two safety ropes. Each end cap has a fixing structure. Each safety rope includes a rope body and a ball head connected to one end of the rope body. The ball head is fixed to the fixing structure, and the other end of the rope body is fixed to one of the ends of the base. The fixing structure includes a protruding post and a fixing hook. One end of the fixing hook is fixed to the bottom of the end cap, and the other end of the fixing hook is spaced apart from the bottom of the end cap to form an entrance. The protruding post is fixed to the bottom of the end cap and located on one side of the entrance. The rope body passes through a central hole in the fixing hook, allowing the ball head to regulate the position of the protruding post and the fixing hook. The design of the fixing structure allows the two end caps to be stably and quickly connected to both ends of the base via the two safety ropes, preventing the tubular globe from falling. In addition, users can temporarily suspend the tubular globe from the base using the two safety ropes to perform wiring work, which greatly simplifies the installation process of the linear lighting fixture and reduces labor costs, while further improving the safety of the linear lighting device.

[0069] Although the above embodiments are described in this specification, it should be noted that they do not limit the scope of the claims of the present invention. Therefore, any changes and modifications to the embodiments described in this specification based on the innovative concept of the present invention, or the replacement of equivalent structures or equivalent processes made using the contents of the specification and drawings of the present invention, or the direct or indirect application of the above technical solutions to other related technical fields, are all within the scope of the claims of the present invention.
