Description

Technical Field

[0001] The present invention relates to a lighting device, particularly a linear lighting device with a base reinforcement structure.

Background Art

[0002] The inverted Fuji type (mountain type) lighting device has a unique shape and lighting characteristics. Its 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 inverted Fuji type lighting device still has many drawbacks to be improved. For example, in the optical structure of the conventional inverted Fuji type lighting device, part of the light generated by the light source substrate is lost, greatly reducing the light efficiency of the lighting device.

[0004] In addition, due to structural limitations, the base of the conventional inverted Fuji type lighting device suffers from insufficient structural strength, and the cost is excessively high, making it unable to meet the requirements of actual applications.

The tubular globe has a light-emitting section and a light-shielding section. The light-emitting section includes a light-emitting surface and two flat plates. The two flat plates are installed on both sides of the light-emitting surface. The light-emitting surface is curved.

[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 equipped with the base reinforcement 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 directly connected or joined 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 reinforcement 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 reinforcement 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 reinforcement 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 reinforcement 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 section 111 includes a light-emitting surface LS and a flat plate FP. The light-emitting surface LS is a curved surface. The flat plate FP has a lower opening PH1, and the bottom of the light-emitting section 111 has an upper opening PH2. The light-shielding section 112 has two grooves Rs installed on both sides thereof. The light-emitting section 111 is installed in the light-shielding section 112, and the flat plate FP protrudes from both sides of the light-shielding section 112, making the cross-section of the tubular globe 11 mushroom-shaped. The width of the lower opening PH1 is greater than the width of the upper opening PH2. The width of the flat plate FP is W1. The width of the lower opening PH1 is equal to the width of the upper opening PH2 minus the total width of the two flat plates FP (W1 × 2). Furthermore, the all-plastic structure described above can prevent the generation of reverse voltage, significantly improving the safety of the linear lighting device 1. The light-emitting section LS has a central section MP, two side sections LP, and two buffer sections BP. The central section MP is installed between the two buffer sections BP. One side section LP is installed on one side of one buffer section BP. The other side section LP is installed on one side of the other buffer section BP. The curvature of the side section LP is greater than the curvature of the central section MP, and the curvature of the central section MP is greater than the curvature of the buffer section BP. The sum of the curvature of the central section MP and the curvature of the two buffer sections BP is less than or equal to the curvature of either one of the side sections LP.

[0013] The support plate 13 is installed within the light-shielding section 112 and is adjacent to the upper opening PH2. 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 on both sides 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 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.

[0015] The power supply module 14 is installed on the other side of the support plate 13 and is located within the light-shielding section 112. The power supply module 14 is electrically connected to the light source substrate 12. The power supply module 14 can be installed directly in the light-shielding section 112 and does not require a separate power supply case. Alternatively, the power supply module 14 may be simply 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 another conventional light source. 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 significantly simplifies the structure of the linear lighting device 1.

[0016] As described above, since the width L1 of the lower opening PH1 is larger than the width L2 of the upper opening PH2, most of the light rays emitted by the light source plate 12 can pass through the light emitting portion 111 and will not be blocked by the light shielding portion 112. Through 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 significantly improved. Also, the design of the curvature of the light emitting portion LS optimizes the above optical structure design, further making the emitted light rays uniform, and making the light rays

[0017] Referring to FIGS. 5, 6, 7, 8, 9 and 10, and simultaneously referring to FIGS. 1 to 4. FIG. 5 is a perspective view of a linear lighting device with a base reinforcement structure according to the second embodiment of the present invention. FIG. 6 is an exploded view of a linear lighting device with a base reinforcement structure according to the second embodiment of the present invention. FIG. 7 is a perspective view of the base of a linear lighting device with a base reinforcement structure according to the second embodiment of the present invention. FIG. 8 is a side view of the base of a linear lighting device with a base reinforcement structure according to the second embodiment of the present invention. FIG. 9 is an explanatory view of the combination of the base and the tubular globe of a linear lighting device with a base reinforcement structure according to the second embodiment of the present invention. FIG. 10 is an explanatory view of the electrical connection wire of a linear lighting device with a base reinforcement 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 those in the above embodiment. The difference from the previous embodiment is that in this example 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, 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. The base 16 includes a bottom plate 161, two end cover walls 162, and two body walls 163. The two end cover walls 162 are installed at both ends of the bottom plate 161, and the two body walls 163 are installed on both sides of the bottom plate 161, making the base 16 trapezoidal. In this embodiment, the base 16 further includes two vertical walls 164, and the two main walls 163 are each connected to the bottom plate 161 via the two vertical walls 164. The thickness of each end cover wall 162 is greater than the thickness of each main wall 163 and less than twice the thickness of each main wall 163. Each end cover wall 162 further has a flange FS, the width of which is greater than twice the thickness of each main wall 163. Each flange FS is installed between the two main walls 163 and is located at both ends of the central groove Cs. The thickness of each end cover wall 162 is 1.4 to 1.7 times the thickness of each main wall 163. The width of each flange FS is 4 to 6 times the thickness of each end cover wall 162. For example, the thickness of the main wall 163 may be 0.35 to 0.4 mm. The thickness of the end cover wall 162 is 4 to 6 times. For example, the thickness of the main wall 163 may be 0.35 to 0.4 mm. The thickness of the end cap wall 162 may be 0.5 to 0.6 mm. The width of the flange FS may be 2 to 3 mm. The structural design that reinforces the base 16 as described above allows the end cap wall 162 to have a relatively large thickness, improving the overall strength of the base 16. The combined structure of the two vertical walls 164 and the two main walls 163 further improves the strength of the sides, thus reducing the thickness of the main wall 163 and the amount of material used in the base 16. Furthermore, the design of the flange FS and the overall thickness / width ratio design can further improve the overall strength of the structure.Therefore, base 16 can save costs by using the least amount of material, while achieving higher overall structural strength.

[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 L1 of the lower aperture PH1 is larger than the width L2 of the upper aperture PH2, 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. 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.

[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 11, 12, and 13, and also to Figures 1 to 10. Figure 11 is an explanatory diagram of the mounting process of a linear lighting device equipped with a base reinforcement structure of a second embodiment of the present invention. Figure 12 is a first enlarged view of the K1 region of Figure 10. Figure 13 is a second enlarged view of the K1 region of Figure 10. As shown in Figure 11, 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 keyholes.

[0030] As shown in Figure 12, 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 13, 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] 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 base reinforcement structure of this embodiment 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 structural design that reinforces the base 16, the end cap wall 162 has a relatively large thickness, and the overall strength of the base 16 can be improved. The combined structure of the two vertical walls 164 and the two main body walls 163 can further improve the strength of the sides, thus reducing the thickness of the main body wall 163 and the amount of material used in the base 16. Furthermore, the design of the flange FS and the overall thickness / width ratio design can further improve the overall strength of the structure.

[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.
