[Modes for carrying out the invention]

[0009] 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.

[0010] The following describes embodiments of a linear lighting device with a base suspension structure 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 joining to that other component, or there may be an intermediary component. When a component is described as “directly connected” or “directly joined” 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.

[0011] Refer to Figures 1, 2, and 3. Figure 1 is a perspective view of a linear lighting device equipped with a base suspension structure according to a first embodiment of the present invention. Figure 2 is a first cross-sectional view of a linear lighting device equipped with a base suspension structure 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 equipped with a base suspension structure 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 equipped with a base suspension structure 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.

[0012] 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.

[0013] 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.

[0014] The light source substrate 12 is installed on one side of the support plate 13 and faces the light emitting part 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 described above 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, light bulbs, etc.). The light source substrate 12 further has a light reflecting paint on it, which can provide a light reflecting effect and improve the light efficiency.

[0015] The power supply module 14 is installed on the other side of the support plate 13 and is located within the light shielding part 112. The power supply module 14 is electrically connected to the light source substrate 12. The power supply module 14 can be directly installed in the light shielding part 112 and does not require a separate power supply case. Also, the power supply module 14 may only 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 design of the built-in power supply module 14 not only improves the safety of the linear lighting device 1 but can also greatly simplify the structure of the linear lighting device 1.

[0016] From the above, since the width L1 at the bottom of the light emitting part 111 is larger than the width L2 at the upper part of the light shielding part 112, most of the light rays emitted by the light source plate 12 can pass through the light emitting part 111 and will not be blocked by the light shielding part 112. With the above optical structure design, the light loss of the light source substrate 12 can be effectively reduced, and the light efficiency of the linear lighting device 1 can be greatly improved.

[0017] Refer to FIGS. 5, 6, 7, 8 and 9, and at the same time refer to FIGS. 1-4. FIG. 5 is a perspective view of a linear lighting device with a base suspension structure according to the second embodiment of the present invention. FIG. 6 is an exploded view of a linear lighting device with a base suspension structure according to the second embodiment of the present invention. FIG. 7 is a side view of the base of a linear lighting device with a base suspension structure according to the second embodiment of the present invention. FIG. 8 is an explanatory view of the combination of the base and the tubular globe of a linear lighting device with a base suspension structure according to the second embodiment of the present invention. FIG. 9 is an explanatory view of the electrical connection line of a linear lighting device with a base suspension structure according to the second embodiment of the present invention. As shown in the figures, the linear lighting device 1 includes a tubular globe 11, a light source substrate 12, a support plate 13, a power module 14, and two end caps 15.

[0018] Each of the above components is the same as in the above 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.

[0019] The base 16 has a central groove Cs. The tubular globe 11 is installed in the central groove Cs, closes the central groove Cs, positions the light-shielding portion 112 within the central groove Cs, and exposes the light-emitting portion 111 from the central groove Cs. Also, both ends of the base 16 may have knockdown holes Bs. When connecting a plurality of linear lighting devices 1 in series, the covers of the plurality of knockdown holes Bs can be removed. Then, the electrical connection line can pass through the knockdown holes Bs to electrically connect the plurality of linear lighting devices 1.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] As described above, 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 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] Refer to Figures 10, 11, 12, and 13, and also refer to Figures 1 to 9. Figure 10 is a first explanatory diagram of the installation process of a linear lighting device equipped with a base suspension structure 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. Figure 13 is an explanatory diagram of the mounting holes for a linear lighting device equipped with a base suspension structure according to a second embodiment of the present invention. As shown in Figure 10, the base 16 has mounting holes Gs at the bottom of the central groove Cs. As shown in Figure 13, the mounting holes Gs include through holes G1 and fixing holes G2 that are connected to each other. The length J1 of the through hole G1 is less than the length J2 of the fixing hole G2, and the width W1 of the through hole G1 is greater than the width W2 of the fixing hole. In another embodiment, the length J1 of the through hole G1 may be greater than or equal to the length J2 of the fixing hole G2, and the width W1 of the through hole G1 may be less than or equal to the width W2 of the fixing hole. The through hole G1 is circular, and the fixing hole G2 is strip-shaped. Thus, the mounting holes Gs may be keyhole-shaped. In another embodiment, the through hole G1 may be square, and the fixing hole G2 may be rectangular. The above shapes are illustrative and not limiting. The area of ​​the through hole G1 is less than the area of ​​the fixing hole G2. In another embodiment, the area of ​​the through hole G1 may be greater than or equal to the area of ​​the fixing hole G2. The mounting holes Gs are located in the center of the central groove Cs. In another embodiment, the mounting holes Gs may be located in a position close to the center of the central groove Cs.

[0030] 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).

[0031] As shown in Figure 12, the base 16 then 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.

[0032] 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.

[0033] The above embodiments are for illustrative purposes only and do not limit the scope of the present invention. Equivalent modifications or changes made based on the linear lighting device having the base suspension structure of these embodiments should still be within the scope of protection of the present invention.

[0034] In summary, according to embodiments of the present invention, the linear lighting device has a special mounting hole design that includes through holes and fixing holes connected to each other. The length of the through holes is shorter than the length of the fixing holes, and the width of the through holes is longer than the width of the fixing holes. The mounting hole design makes the installation process more convenient and saves labor costs, as the user can temporarily fix the base to the ceiling panel and then fix both ends of the base.

[0035] While the embodiments described herein are explained, it should be noted that this does not limit the scope of the claims of the present invention. Therefore, any changes and modifications to the embodiments described herein, or substitution of equivalent structures or processes using the contents of the specification and drawings of the present invention, or direct or indirect application of the above-described technology to other related technical fields, based on the innovative concept of the present invention, are all included within the scope of the claims of the present invention.
