Description

Technical Field

[0001] The present invention relates to a lighting device, particularly a linear lighting device having a built-in power module.

Background Art

[0002] The reverse Fuji type (mountain type) lighting device has a unique shape and lighting characteristics, and the main feature is the design of a triangular base or an inverted conical base. The above design is advantageous for the uniform distribution of light rays and can efficiently utilize space, so it is widely applied to various buildings.

[0003] However, the conventional reverse Fuji type lighting device still has many drawbacks to be improved.

[0004] In addition, in the conventional reverse Fuji type lighting device, an external power module is usually used, so the structure is complex and there is still room for further improvement in safety.

[0005] In addition, the installation process of the conventional reverse Fuji type lighting device is relatively complex, requiring a lot of labor and causing an increase in labor costs.

The base plate is fixed to the bottom of a central groove, the two protrusions are respectively installed on the two side walls, and the light-shielding portion has two grooves, each installed on either side of the light-shielding portion, and the two protrusions are embedded in the two grooves, respectively, to fix the clip to the light-shielding portion.

The protruding column is fixed to the bottom of the end cover and is located on one side of the entrance. The rope body passes through the central hole of the fixing hook and the position of the protruding column and fixing hook is regulated by the ball head. [Effects of the Invention]

[0017] Based on the above, a linear lighting device having a built-in power supply module according to an embodiment of the present invention can have one or more of the following advantages. (1) In one embodiment of the present invention, a linear lighting device having a built-in power supply module includes a tubular globe, a support plate, a light source substrate, and a power supply module. The tubular globe has a light-emitting section and a light-shielding section. The light-emitting surface of the light-emitting section is curved. The bottom of the light-emitting section has a lower opening, and the upper part of the light-shielding section has an upper opening. The bottom of the light-emitting section is connected to the upper part of the light-shielding section. The support plate is installed inside the light-shielding section and is adjacent to the upper opening. The light source substrate is installed on one side of the support plate and faces the light-emitting section. The power supply module is installed on the other side of the support plate and is located inside the light-shielding section. The power supply module is electrically connected to the light source substrate, and one end of the power supply module is adjacent to one end of the tubular globe. From the above, it can be seen that electronic components such as the light source substrate and power supply module of the linear lighting device are all mounted inside the tubular globe. The above-mentioned tubular globe is made of plastic, and the tubular globe can be made of an all-plastic structure. The above-mentioned all-plastic structure can effectively prevent the generation of reverse voltage and improve safety, thereby significantly improving the safety of the linear lighting device. (2) In one embodiment of the present invention, the power supply module of the linear lighting device is installed in a 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-described built-in power supply module design not only effectively prevents the generation of reverse voltage and improves safety, but can also greatly simplify the structure of the linear lighting device. (3) In one embodiment of the present invention, the width of the bottom of the light-emitting portion of the tubular globe of the linear illumination 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 rays emitted from the light source substrate can pass through the light-emitting portion without being obstructed by the light-shielding portion. The above optical structure design effectively reduces the light loss of the light source substrate and significantly improves the light efficiency of the linear illumination device. (4) In one embodiment of the present invention, the linear lighting device further comprises a base and a plurality of clips, and the tubular globe is installed on the base. The base has a central groove, and the tubular globe is installed on the central groove, closing the central groove, positioning the light-shielding portion within the central groove, and exposing the light-emitting portion from the central groove. Each 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 light-shielding portion has two grooves installed on both sides of the light-shielding portion, and the two protrusions are embedded in the two grooves, respectively, fixing the clip and the light-shielding portion to each other. With the above-described one-sided fixing structure, the tubular globe can be fixed to the base without the need to install a fixing structure, simplifying the structure of the tubular globe. In addition, the plurality of clips are not exposed from the central groove, which simplifies the structure of the base. With the above structural design, the linear lighting device is easier to transport and less likely to be damaged during transport. (5) In one embodiment of the present invention, the light source substrate of the linear lighting device is mounted on a support plate, the support plate may be made of a material with high thermal conductivity (various metals such as copper, iron, aluminum, and stainless steel), and is installed inside a tubular globe. Therefore, the support plate not only provides a heat dissipation effect but also achieves a support function and can increase the structural strength of the tubular globe. Furthermore, the light source substrate may have a light-reflective coating to further increase the light efficiency. In this way, the service life of the linear lighting device can be effectively extended, the light efficiency can be further improved, and the requirements of actual applications can be met. (6) In one embodiment of the present invention, the linear lighting device further comprises two end covers and two safety ropes. The two end covers are installed at both ends of the tubular globe and are connected to both ends of the base via the two safety ropes. Each end cover 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 end of the base. The fixing structure includes a protruding column and a fixing hook. One end of the fixing hook is fixed to the bottom of the end cover, and the other end of the fixing hook forms an entrance with a gap from the bottom of the end cover. The protruding column is fixed to the bottom of the end cover and is located on one side of the entrance. The rope body passes through a hole in the center of the fixing hook, causing the ball head to be positioned according to the position of the protruding column and the fixing hook. The design of the fixing structure allows the two end covers to be stably and quickly connected to both ends of the base via the two safety ropes, preventing the tubular globe from falling. Furthermore, the user can temporarily suspend the tubular globe from the base via the two safety ropes and perform wiring work. This significantly simplifies the installation process of the linear lighting fixture and reduces labor costs. At the same time, it further improves the safety of the linear lighting device.

Embodiments for Carrying Out the Invention

[0019] The following embodiments describe the detailed features and advantages of the present invention, which are sufficient to enable those skilled in the art to understand and implement the technical aspects of the invention, and which, through the disclosures, claims, and drawings herein, will be readily understood by those skilled in the art.

[0020] The following describes embodiments of a linear lighting device having a built-in power supply module of the present invention, with reference to the relevant drawings. 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 described as “connected” or “joined” to another component, it may be a direct connection or coupling to that other component, or there may be an intermediary component. When a component is described as “directly connected” or “directly coupled” to another component, there is no intermediary component, and other terms used to describe relationships between components or layers should be interpreted similarly. For ease of understanding, the same components in the following embodiments are denoted by the same reference numerals.

[0021] Refer to Figures 1, 2, and 3. Figure 1 is a perspective view of a linear lighting device having a built-in power supply module according to a first embodiment of the present invention. Figure 2 is a first cross-sectional view of a linear lighting device having a built-in power supply module according to a first embodiment of the present invention (without support plate, light source substrate, and power supply module). Figure 3 is a second cross-sectional view of a linear lighting device having a built-in power supply module according to a first embodiment of the present invention (with support plate, light source substrate, and power supply module). Figure 4 is a third cross-sectional view of a linear lighting device having a built-in power supply module according to a 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 covers 15.

[0022] The tubular globe 11 has a light-emitting section 111 and a light-shielding section 112. The two end caps 15 are installed at both ends of the tubular globe 11, respectively. In this embodiment, the tubular globe 11 is an all-plastic structure made of plastic (this material may be various conventional plastic materials, such as PMMA or PC, but is not limited to these). The light-emitting surface LS of the light-emitting section 111 is curved. The bottom of the light-emitting section 111 has a bottom opening, and the top of the light-shielding section 112 has an top opening. The light-shielding section 112 has two grooves Rs installed on both sides thereof. The bottom of the light-emitting section 111 is connected to the top of the light-shielding section 112. Also, the width L1 of the bottom of the light-emitting section 111 is greater than the width L2 of the top of the light-shielding section 112. The all-plastic structure described above can effectively prevent the generation of reverse voltage, and the safety of the linear lighting device 1 can be greatly improved.

[0023] The support plate 13 is installed inside the light-shielding section 112 and is 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 the two inner walls of the light-shielding section 112, respectively. Each inner wall has an L-shaped hook section V1 and a position-regulating plate V2. The position-regulating plate V2 is installed above the L-shaped hook section V1. Two L-shaped hook sections V1 are embedded in each side of the support plate 13, and the two position-regulating plates V2 provide a position-regulating function, preventing the support plate 13 from detaching from the two L-shaped hook sections 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, or stainless steel. Therefore, the support plate 13 can not only provide a heat dissipation effect but also achieve a support function and increase 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 section 111. The light source substrate 12 may include a circuit board 121 and a plurality of light sources 122, the plurality of light sources 122 being 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 (fluorescent lamps, light bulbs, etc.). The light source substrate 12 may further have a light-reflective coating to provide a light-reflecting effect and improve light efficiency.

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

[0026] As described above, since the width L1 at the bottom of the light-emitting section 111 is greater than the width L2 at the top of the light-shielding section 112, most of the light rays emitted by the light source plate 12 can pass through the light-emitting section 111 and are not blocked by the light-shielding section 112. With the optical structure design described above, the light loss of the light source substrate 12 can be effectively reduced, and the light efficiency of the linear illumination device 1 can be greatly improved.

[0027] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and equivalent modifications or changes made based on the linear lighting device having the built-in power supply module of this embodiment should still be within the scope of protection of the present invention.

[0028] Refer to Figures 5, 6, 7, 8, and 9, and also refer to Figures 1 to 4. Figure 5 is a perspective view of a linear lighting device having a built-in power supply module according to a second embodiment of the present invention. Figure 6 is an exploded view of a linear lighting device having a built-in power supply module according to a second embodiment of the present invention. Figure 7 is a side view of the base of a linear lighting device having a built-in power supply module according to a 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 built-in power supply module according to a second embodiment of the present invention. Figure 9 is an explanatory diagram of the electrical connection lines of a linear lighting device having a built-in power supply module according to a second 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 covers 15.

[0029] Each of the above components is the same as in the above embodiment. The difference from the above embodiment is that in this example, 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, closing the central groove Cs, positioning the light-shielding portion 112 within the central groove Cs, and exposing the light-emitting portion 111 from the central groove Cs. The base 16 may also have knockdown holes Bs at both ends. When connecting multiple linear lighting devices 1 in series, the covers of the multiple knockdown holes Bs can be removed. After that, electrical connection wires can pass through the knockdown holes Bs to electrically connect the multiple linear lighting devices 1.

[0031] The two clips 17 described above may be made of a metal material such as copper, iron, aluminum, or stainless steel. Each clip 17 is U-shaped and includes a base plate 171, two side walls 172, and two protrusions 173. The base 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, each installed on either side of the light-shielding portion 112, and the two protrusions 173 are respectively inserted into the two grooves Rs, fixing the clips 17 and the light-shielding portion 112 together. 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 requirements. In another embodiment, the linear illumination device 1 may include only one clip 17 or three or more clips 17. Due to the aforementioned one-sided locking structure, the tubular globe 11 can be fixed to the base 16 without the need to install a fixing structure, thereby simplifying the structure of the tubular globe 11. Furthermore, the multiple clips 17 are not exposed in the central groove Cs, further simplifying the structure of the base 16. With the above structural design, the linear lighting device 1 becomes more convenient to transport and less susceptible to damage during transport.

[0032] The two end covers 15 are provided at both ends of the tubular globe 11 and are connected to both ends of the base 16 via the two safety ropes 18. The two end covers 15 provide waterproofing and dustproofing, 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 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 cover 15. A sealing ring SR (such as a rubber ring) can be installed in this connection hole to achieve waterproof and dustproof effects. The connection terminal 20 can be installed on the back of the tubular globe 11. In this embodiment, the electrical connection line 19 can be fixed to the back of the tubular globe 11 by tape TP or other similar methods, but is not limited thereto.

[0034] As a result, since the width of the bottom of the light-emitting section 111 is greater than the width of the top of the light-shielding section 112, most of the light emitted by the light source plate 12 can pass through the light-emitting section 111 and is not blocked by the light-shielding section 112. The above optical structure design effectively reduces the light loss of the light source substrate 12 and significantly improves the light efficiency of the linear illumination device 1.

[0035] Furthermore, electronic components such as the light source substrate 12 and power module 14 of the linear lighting device 1 are installed inside 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 the generation of reverse voltage, significantly improving the safety of the linear lighting device 1.

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

[0037] Furthermore, the aforementioned one-sided fixing structure eliminates the need for a separate fixing structure for the tubular globe 11, allowing it to be fixed to the base 16 and simplifying the structure of the tubular globe 11. In addition, the multiple clips 17 are not exposed in the central groove Cs, further simplifying the structure of the base 16. This structural design makes the linear lighting device 1 more convenient to transport and less susceptible to damage during transport.

[0038] Furthermore, the light source substrate 12 of the linear lighting device 1 is mounted on its support plate 13. The support plate 13 may be made of a highly thermally conductive material (various metals such as copper, iron, aluminum, and stainless steel) and is installed inside the tubular globe 11. Therefore, the support plate 13 not only provides a heat dissipation effect but also achieves a support function, thereby increasing the structural strength of the tubular globe 11. In addition, the light source substrate 12 may have a light-reflective coating to further improve light efficiency. In this way, the service life of the linear lighting device 1 can be effectively extended, light efficiency can be further improved, and the requirements of actual applications can be met.

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

[0040] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and equivalent modifications or changes made based on the linear lighting device having the built-in power supply module of this embodiment should still be within the scope of protection of the present invention.

[0041] Conventional inverted-V-shaped lighting devices still have many shortcomings that need improvement. For example, the optical structure of conventional inverted-V-shaped lighting devices causes some of the light generated by the light source substrate to be lost, significantly reducing the light efficiency of the lighting device. Also, conventional inverted-V-shaped lighting devices usually use an external power supply module, resulting in a complex structure and room for further improvement in safety. Furthermore, the installation process of conventional inverted-V-shaped lighting devices is relatively complex, requiring a lot of labor and leading to increased labor costs. In contrast, according to an embodiment of the present invention, the linear lighting device includes a tubular globe, a support plate, and a light source substrate. The tubular globe has a light-emitting part and a light-shielding part. The light-emitting surface of the light-emitting part is curved. The bottom of the light-emitting part has a lower opening, and the top of the light-shielding part has an upper opening. The bottom of the light-emitting part is connected to the top of the light-shielding part. The support plate is installed inside the light-shielding part and is adjacent to the upper opening. The light source substrate is installed on one side of the support plate and faces the light-emitting part. The power supply module is installed on the other side of the support plate and is located inside the light-shielding part. The power supply module is electrically connected to the light source substrate, and one end of the power supply module is adjacent to one end of the tubular globe. From the above, it can be seen that the electronic components of the linear lighting device, such as the light source substrate and the power supply module, are all mounted inside the tubular globe. The aforementioned tubular globe is made of plastic, and the tubular globe can be made entirely of plastic. This all-plastic structure effectively prevents the generation of reverse voltage, improving safety and significantly enhancing the safety of the linear lighting device.

[0042] Furthermore, according to embodiments of the present invention, the power supply module of the linear lighting device is installed in a tubular globe, and the power supply module is not installed in a power supply case but is simply covered with a plastic film. The above-described built-in power supply module design not only effectively prevents the generation of reverse voltage and improves safety, but also significantly simplifies the structure of the linear lighting device.

[0043] Furthermore, 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 illumination 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 rays emitted from the light source substrate can pass through the light-emitting portion without being obstructed by the light-shielding portion. With the above-described optical structure design, the light loss of the light source substrate can be effectively reduced, and the light efficiency of the linear illumination device can be greatly improved.

[0044] Furthermore, according to an embodiment of the present invention, the linear lighting device further comprises a base and a plurality of clips, and the tubular globe is installed on the base. The base has a central groove, and the tubular globe is installed on the central groove, closing the central groove, positioning the light-shielding portion within the central groove, and exposing the light-emitting portion from the central groove. Each 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 light-shielding portion has two grooves installed on both sides of the light-shielding portion, and the two protrusions are embedded in the two grooves, respectively, fixing the clip and the light-shielding portion to each other. With the above-described one-sided fixing structure, the tubular globe can be fixed to the base without the need to install a fixing structure, simplifying the structure of the tubular globe. In addition, the plurality of clips are not exposed from the central groove, which simplifies the structure of the base. With the above structural design, the linear lighting device is more convenient to transport and less prone to damage during transport.

[0045] Furthermore, according to embodiments 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 material with high thermal conductivity (various metals such as copper, iron, aluminum, and stainless steel) and is installed inside a tubular globe. Therefore, the support plate not only provides a heat dissipation effect but also achieves a support function and can increase the structural strength of the tubular globe. In addition, the light source substrate may be further coated with a light-reflective paint to improve light efficiency. In this way, the service life of the linear lighting device can be effectively extended, light efficiency can be further improved, and the requirements of actual applications can be met. From the above, it can be seen that a linear lighting device having a built-in power supply module according to embodiments of the present invention can certainly achieve excellent technical effects.

[0046] Refer to Figures 10, 11, and 12, and also to Figures 1 to 9. Figure 10 is a first explanatory diagram of the mounting process of a linear lighting device having a built-in power supply module according to a second embodiment of the present invention. Figure 11 is a first partial enlarged view of the K1 region in Figure 10. Figure 12 is a second partial enlarged view of the K1 region in Figure 10. As shown in Figure 10, the bottom of the central groove Cs of the base 16 further has mounting holes Gs, and the mounting holes Gs may be in the shape of a keyhole.

[0047] As shown in Figure 11, the user can first fix the fixing member FX (screw, nail, or other similar member) to the ceiling. Then, the user can place the base 16 on the ceiling, align the mounting holes Gs with the fixing member FX, and insert the head of the fixing member into one end of the mounting holes Gs. After that, the user can push the base 16 and move it toward the other end of the mounting holes Gs (arrow A1 in the figure).

[0048] Subsequently, as shown in Figure 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 the other fixing members FX.

[0049] Without the design of mounting holes Gs, the user would first need to fix one end of the base 16 to the ceiling, while the other end of the base 16 would need to be grasped by another installer, making installation extremely inconvenient. The design of mounting holes Gs allows the user to temporarily fix the base 16 to the ceiling and then fix both ends of the base 16, thus making the installation process more convenient and saving effort.

[0050] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and equivalent modifications or changes made based on the linear lighting device having the built-in power supply module of this embodiment should still be within the scope of protection of the present invention.

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

[0052] As shown in Figure 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 cover 15 has a fixing structure, which includes a protruding column 151 and a fixing hook 152. One end of the fixing hook 152 is fixed to the bottom of the end cover 15, and the other end of the fixing hook 152 forms an entrance Es with a gap between it and the bottom of the end cover 15. The protruding column 151 is fixed to the bottom of the end cover 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 convex column 151 and the fixing hook 152 (arrow A2 in the figure).

[0054] As shown in Figure 15, the user moves the ball head 182 toward the space between the convex column 151 and the fixing hook 152, and inserts one end of the rope body 181 closest to the ball head 182 into the space between the convex column 151 and the fixing hook 152. The user then pulls the rope body 181 toward the entrance Es (arrow A3 in the figure), thereby inserting the rope body 181 through the entrance Es into the central hole of the fixing hook 152.

[0055] As shown in Figure 16, the rope body 181 enters the central hole of the fixing hook 152 through the entrance Es, and then the rope body 181 can pass through the central hole of the fixing hook 152. In this way, the ball head 182 can be subject to the positional constraints of the convex column 151 and the fixing hook 152. In this way, the ball head 182 can be fixed to the fixing structure, and the other end of the rope body 181 is fixed to one of the two ends of the base 16.

[0056] The above-described fixing structure design allows the two end covers 15 to be stably and quickly connected to both ends of the base 16 via the two safety ropes 18. The user can temporarily suspend the tubular globe 11 from the base 16 via the two safety ropes 18 and perform wiring work. Therefore, the installation process of the linear lighting device 1 can be greatly simplified and labor costs can be reduced.

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

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

[0059] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and equivalent modifications or changes made based on the linear lighting device having the built-in power supply module of this embodiment should still be within the scope of protection of the present invention.

[0060] Refer to Figures 17 and 18. Figure 18 is a perspective view of a linear lighting device having a built-in power supply module according to a third embodiment of the present invention. Figure 18 is a perspective view of a linear lighting device having a built-in power supply module 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 17 and base 16'' shown in Figure 18) to give the linear lighting device 1 different appearances and functions.

[0061] Therefore, the tubular globe 11 can be sold individually as a separate product, allowing for more flexible use. At the same time, the above structural design effectively reduces inventory, thus lowering costs.

[0062] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and equivalent modifications or changes made based on the linear lighting device having the built-in power supply module of this embodiment should still be within the scope of protection of the present invention.

[0063] In summary, according to embodiments of the present invention, the linear lighting device includes a tubular globe, a support plate, and a light source substrate. The tubular globe has a light-emitting section and a light-shielding section. The light-emitting surface of the light-emitting section is curved. The bottom of the light-emitting section has a lower opening, and the upper part of the light-shielding section has an upper opening. The bottom of the light-emitting section is connected to the upper part of the light-shielding section. The support plate is installed inside the light-shielding section and is adjacent to the upper opening. The light source substrate is installed on one side of the support plate and faces the light-emitting section. The power supply module is installed on the other side of the support plate and is located inside the light-shielding section. The power supply module is electrically connected to the light source substrate, and one end of the power supply module is adjacent to one end of the tubular globe. From the above, it can be seen that the electronic components of the linear lighting device, such as the light source substrate and the power supply module, are all mounted inside the tubular globe. The tubular globe described above is made of plastic, and the tubular globe can be made of an all-plastic structure. The aforementioned all-plastic structure effectively prevents the generation of reverse voltage, improving safety and significantly improving the safety of the linear lighting device.

[0064] Furthermore, according to embodiments of the present invention, the power supply module of the linear lighting device is installed in a tubular globe, and the power supply module is not installed in a power supply case but is simply covered with a plastic film. The above-described built-in power supply module design not only effectively prevents the generation of reverse voltage and improves safety, but also significantly simplifies the structure of the linear lighting device.

[0065] Furthermore, 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 illumination 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 rays emitted from the light source substrate can pass through the light-emitting portion without being obstructed by the light-shielding portion. With the above-described optical structure design, the light loss of the light source substrate can be effectively reduced, and the light efficiency of the linear illumination device can be greatly improved.

[0066] Furthermore, according to an embodiment of the present invention, the linear lighting device further comprises a base and a plurality of clips, and the tubular globe is installed on the base. The base has a central groove, and the tubular globe is installed on the central groove, closing the central groove, positioning the light-shielding portion within the central groove, and exposing the light-emitting portion from the central groove. Each 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 light-shielding portion has two grooves installed on both sides of the light-shielding portion, and the two protrusions are embedded in the two grooves, respectively, fixing the clip and the light-shielding portion to each other. With the above-described one-sided fixing structure, the tubular globe can be fixed to the base without the need to install a fixing structure, simplifying the structure of the tubular globe. In addition, the plurality of clips are not exposed from the central groove, which simplifies the structure of the base. With the above structural design, the linear lighting device is more convenient to transport and less prone to damage during transport.

[0067] Furthermore, according to embodiments 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 material with high thermal conductivity (various metals such as copper, iron, aluminum, and stainless steel) and is installed inside a tubular globe. Therefore, the support plate not only provides a heat dissipation effect but also achieves a support function, thereby increasing the structural strength of the tubular globe. In addition, the light source substrate may be further coated with a light-reflective paint to improve light efficiency. In this way, the service life of the linear lighting device can be effectively extended, light efficiency can be further improved, and the requirements of actual applications can be met.

[0068] Furthermore, according to embodiments of the present invention, the linear lighting device further comprises two end caps and two safety ropes. The two end caps are installed at both ends of the tubular globe and are 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 end of the base. The fixing structure includes a protruding column 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 forms an entrance with a gap from the bottom of the end cap. The protruding column is fixed to the bottom of the end cap and is located on one side of the entrance. The rope body passes through a hole in the center of the fixing hook, causing the ball head to be positioned according to the position of the protruding column 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. Furthermore, the user can temporarily suspend the tubular globe from the base via the two safety ropes and perform wiring work. This significantly simplifies the installation process of the linear lighting fixture and reduces labor costs. At the same time, it further improves the safety of the linear lighting device.
