Description

Technical Field

[0001] The utility model relates to a lighting device, in particular to a linear lighting device with a single-side locking structure. Background Art

[0002] The inverse Fuji-shaped (mountain-shaped) lighting device has a unique shape and lighting characteristics, and its main feature is the design of its triangular base or inverted cone base. The above design is conducive to the uniform distribution of light and can efficiently use space, so it has been widely used in various buildings.

[0003] However, the existing inverse Fuji-shaped lighting devices still have many disadvantages to be improved. For example, the optical structure of the existing inverse Fuji-shaped lighting devices may cause a portion of the light generated by the light source panel to be lost, which greatly reduces the light efficiency of the lighting device.

[0004] In addition, both the lampshade and the base of the existing inverse Fuji-shaped lighting device need to have a locking structure, which makes the structures of the lampshade and the base more complicated and easy to be damaged during transportation.

[0005] In addition, the installation procedure of the existing reverse Fuji-shaped lighting device is relatively complicated and requires a lot of manpower, resulting in an increase in labor costs. Utility Model Content

[0012] In one embodiment, both ends of the base have knockout holes.

[0013] In one embodiment, the linear lighting device further comprises two end covers and two safety ropes. The two end covers are respectively arranged at two ends of the tubular lampshade and are respectively connected to two ends of the base through the two safety ropes.

[0016] As described above, the linear lighting device with a single-side locking structure according to the embodiments of the present invention may have one or more of the following advantages:

[0017] (1) In one embodiment of the utility model, a linear lighting device with a single-side locking structure includes a tubular lampshade, a support plate, a light source plate, a base and a clamp. The tubular lampshade has a light-emitting portion and a light-shielding portion. The light-emitting surface of the light-emitting portion is a curved surface. The bottom of the light-emitting portion has a lower opening, and the top of the light-shielding portion has an upper opening and two grooves respectively arranged on both sides thereof. The bottom of the light-emitting portion is connected to the top of the light-shielding portion. The support plate is arranged in the light-shielding portion and is adjacent to the upper opening.

The base has a central groove, and the tubular lampshade is arranged on the central groove and closes the central groove. The clamp 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 respectively arranged on the two side walls. The two protrusions are respectively embedded in the two grooves, so that the clamp and the light-shielding portion are fixed to each other. Through the above-mentioned single-side locking structure, the tubular lampshade can be fixed to the base without providing a locking structure, so that the structure of the tubular lampshade is more simplified. In addition, the plurality of clips are not exposed in the central groove, so that the structure of the base can be simplified. The above structural design makes the linear lighting device more convenient to transport and less likely to be damaged during transportation.

[0018] (2) In one embodiment of the utility model, the width of the bottom of the light-emitting portion of the tubular lampshade of the linear lighting device is greater than the width of the top of the light-shielding portion. Since 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 board can pass through the light-emitting portion without being blocked by the light-shielding portion. The above optical structure design can effectively reduce the light loss of the light source board, thereby greatly improving the light efficiency of the linear lighting device.

[0019] (3) In one embodiment of the utility model, the light source board and the power module and other electronic components of the linear lighting device are all arranged in the tubular lampshade. The above-mentioned tubular lampshade can be made of plastic, so that the tubular lampshade is a full plastic structure. The above-mentioned full plastic structure can effectively prevent the generation of reverse voltage, so that the safety of the linear lighting device can be greatly improved.

[0020] (4) In one embodiment of the present invention, the power module of the linear lighting device is disposed in the tubular lampshade thereof, and the power module is not disposed in the power box, but is only covered by a plastic film. The above-mentioned built-in power module design can not only effectively prevent the generation of reverse voltage to improve safety, but also greatly simplify the structure of the linear lighting device.

[0021] (5) In one embodiment of the utility model, the light source board of the linear lighting device is arranged on its support plate, and the support plate can be made of a high thermal conductivity material (various metals, such as copper, iron, aluminum, stainless steel, etc.) and is arranged in the tubular lampshade. Therefore, the support plate can not only provide a heat dissipation effect, but also achieve a supporting effect to improve the structural strength of the tubular lampshade. In addition, the light source board also has a reflective coating to improve the light effect. In this way, the service life of the linear lighting device can be effectively improved and the light effect can be further improved to meet the needs of practical applications.

[0022] (6) In one embodiment of the utility model, the linear lighting device further comprises two end caps and two safety ropes. The two end caps are respectively arranged at the two ends of the tubular lampshade and are respectively connected to the two ends of the base through the two safety ropes. Each end cap has a fixing structure. Each safety rope comprises 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 two ends of the base. The fixing structure comprises a 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 is spaced from the bottom of the end cap to form an entrance. The column is fixed to the bottom of the end cap and is located on one side of the entrance. The rope body passes through the central hole of the fixing hook so that the ball head is limited by the column and the fixing hook at the same time. Through the design of the fixing structure, the two end caps can be firmly and quickly connected to the two ends of the base through the two safety ropes to prevent the tubular lampshade from falling. In addition, the user can also temporarily hang the tubular lampshade on the base through the two safety ropes to perform wiring operations. Therefore, the installation procedure of the linear lighting device can be greatly simplified to reduce labor costs. At the same time, the safety of the linear lighting device can also be further improved. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 1 It is a three-dimensional view of a linear lighting device with a single-side locking structure according to the first embodiment of the utility model. Figure 2 It is a first cross-sectional view of the linear lighting device with a single-side locking structure according to the first embodiment of the utility model (without the supporting plate, the light source plate and the power module). Figure 3 It is a second cross-sectional view of the linear lighting device with a single-side locking structure according to the first embodiment of the utility model (including a support plate, a light source plate and a power module). Figure 4The third cross-sectional view of the linear lighting device with a single-side locking structure of the first embodiment of the utility model is shown in FIG.

[0046] The tubular lampshade 11 has a light-emitting portion 111 and a light-shielding portion 112. The two end covers 15 are respectively arranged at the two ends of the tubular lampshade 11. In the present embodiment, the tubular lampshade 11 is a full plastic structure made of plastic (this material can be various existing plastic materials, which can be but not limited to PMMA, PC, etc.). The light-emitting surface LS of the light-emitting portion 111 is a curved surface. 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 respectively arranged on both sides thereof. The bottom of the light-emitting portion 111 is connected to the top 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 above-mentioned full plastic structure can effectively prevent the generation of reverse voltage, so that the safety of the linear lighting device 1 can be greatly improved.

[0047] The support plate 13 is disposed in the shading portion 112 and adjacent to the upper opening. The cross section of the support plate 13 is U-shaped, and the two sides of the support plate 13 are respectively fixed to the two inner walls of the shading portion 112. Each inner wall has an L-shaped hook portion V1 and a limit plate V2. The limit plate V2 is disposed above the L-shaped hook portion V1. The two sides of the support plate 13 can be respectively embedded in the above-mentioned two L-shaped hook portions V1, and the above-mentioned two limit plates V2 can provide a limit function to prevent the support plate 13 from being separated from the above-mentioned two L-shaped hook portions V1. The support plate 13 can be a high thermal conductivity material. This material can be various metals, such as copper, iron, aluminum, stainless steel, etc. Therefore, the support plate 13 can not only provide a heat dissipation effect, but also achieve a supporting effect to enhance the structural strength of the tubular lampshade 11.

[0048] The light source board 12 is disposed on one side of the support board 13 and faces the light emitting portion 111. The light source board 12 may include a circuit board 121 and a plurality of light sources 122, and the plurality of light sources 122 are disposed on the circuit board 121. In the present embodiment, the plurality of light sources 122 may be light emitting diodes (LEDs). In another embodiment, the light source board 12 may also be replaced by other light emitting units (such as fluorescent lamps, light bulbs, etc.). The light source board 12 also has a reflective coating, which can provide a reflective effect to enhance the light effect.

[0049] The power module 14 is disposed on the other side of the support plate 13 and is located in the light shielding portion 112. The power module 14 is electrically connected to the light source plate 12, and the power module 14 can be directly disposed in the light shielding portion 112 without the need for an additional power box. In addition, the power module 14 can be wrapped only by a plastic film. In one embodiment, the power module 14 is a light emitting diode driver. In another embodiment, the power module 14 can also be a driver for other existing light sources. The above-mentioned built-in power module 14 design can not only improve the safety of the linear lighting device 1, but also greatly simplify the structure of the linear lighting device 1.

[0050] As can be seen from the above, since 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, most of the light emitted by the light source board 12 can pass through the light emitting portion 111 without being blocked by the light shielding portion 112. The above optical structure design can effectively reduce the light loss of the light source board 12, and greatly improve the light efficiency of the linear lighting device 1.

[0051] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the linear lighting device with a single-side locking structure according to this embodiment should still be included in the patent scope of the present invention.

[0052] See also Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 , and please also refer to Figures 1 to 4 . Figure 5 It is a three-dimensional view of a linear lighting device with a single-side locking structure according to a second embodiment of the present invention. Figure 6 It is an exploded view of a linear lighting device with a single-side locking structure according to the second embodiment of the present invention. Figure 7 It is a side view of a base of a linear lighting device with a single-side locking structure according to a second embodiment of the present invention. Figure 8 It is a schematic diagram of a combination of a base and a tubular lampshade of a linear lighting device with a single-side locking structure according to a second embodiment of the present invention. Fig. 9 The schematic diagram of the electrical connection line of the linear lighting device with a single-side locking structure of the second embodiment of the present invention is shown in the figure. As shown in the figure, the linear lighting device 1 includes a tubular lampshade 11, a light source plate 12, a support plate 13, a power module 14 and two end covers 15.

[0053] 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 .

[0054] The base 16 has a central groove Cs. The tubular lampshade 11 is disposed on the central groove Cs and closes the central groove Cs, so that the light shielding portion 112 is located in the central groove Cs and the light emitting portion 111 is exposed outside the central groove Cs. In addition, both ends of the base 16 may also have knockout holes Bs. If multiple linear lighting devices 1 are to be connected in series, the covers of the knockout holes Bs may be removed. Then, the electrical connection wires may pass through the knockout holes Bs to electrically connect the multiple linear lighting devices 1.

[0055] The two clips 17 can be made of metal materials, such as copper, iron, aluminum, stainless steel, etc. 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 arranged on the two side walls 172. Each clip 17 is not exposed in the central groove Cs. As mentioned above, the shading portion 112 has two grooves Rs respectively arranged on both sides of the shading portion 112, and the two protrusions 173 are respectively embedded in the two grooves Rs, so that the clip 17 and the shading portion 112 are fixed to each other. In this way, the tubular lampshade 11 is fixed to the base 16 through the two clips 17. The number of clips 17 can be adjusted according to actual needs; in another embodiment, the linear lighting device 1 can include only one clip 17 or more than three clips 17. Through the above-mentioned single-side locking structure, the tubular lampshade 11 can be fixed on the base 16 without providing a locking structure, so that the structure of the tubular lampshade 11 is further simplified. In addition, the above-mentioned multiple clips 17 are not exposed in the central groove Cs, so that the structure of the base 16 can also be further simplified. The above-mentioned structural design makes the linear lighting device 1 more convenient to transport and is not easily damaged during transportation.

[0056] The two end covers 15 are respectively disposed at the two ends of the tubular lampshade 11, and are respectively connected to the two ends of the base 16 through the two safety ropes 18. The two end covers 15 can achieve waterproof and dustproof effects to improve the safety and service life of the linear lighting device 1.

[0057] The linear lighting device 1 also has an electrical connection line 19 and a terminal 20. The power module 14 is connected to the electrical connection line 19, and the electrical connection line 19 is connected to the terminal 20 after passing through the connection hole. The connection hole is set at a position close to one of the end caps 15. The connection hole can be provided with a sealing ring SR (such as a rubber ring) to achieve waterproof and dustproof effects. The terminal 142 can be set at the back of the tubular lampshade 11. In this embodiment, the electrical connection line 19 can be fixed to the back of the tubular lampshade 11 by means of tape TP or other similar methods, but it is not limited thereto.

[0058] As can be seen from the above, since 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, most of the light emitted by the light source board 12 can pass through the light emitting portion 111 without being blocked by the light shielding portion 112. The above optical structure design can effectively reduce the light loss of the light source board 12, and greatly improve the light efficiency of the linear lighting device 1.

[0059] In addition, the light source board 12 and the power module 14 and other electronic components of the linear lighting device 1 are all disposed in the tubular lampshade 11. The tubular lampshade 11 can be made of plastic, so that the tubular lampshade 11 is a full plastic structure. The full plastic structure can effectively prevent the generation of reverse voltage, so that the safety of the linear lighting device 1 can be greatly improved.

[0060] In addition, the power module 14 of the linear lighting device 1 is disposed in the tubular lampshade 11 thereof, and the power module 14 is not disposed in a power box, but can be only covered by a plastic film. The above-mentioned built-in power module design can not only effectively prevent the generation of reverse voltage to improve safety, but also greatly simplify the structure of the linear lighting device 1.

[0061] Furthermore, through the above-mentioned single-side locking structure, the tubular lampshade 11 can be fixed on the base 16 without providing a locking structure, so that the structure of the tubular lampshade 11 is further simplified. In addition, the above-mentioned multiple clips 17 are not exposed in the central groove Cs, so that the structure of the base 16 can also be further simplified. The above-mentioned structural design makes the linear lighting device 1 more convenient to transport and is not easily damaged during transportation.

[0062] In addition, the light source board 12 of the linear lighting device 1 is arranged on its support board 13, and the support board 13 can be made of a high thermal conductivity material (various metals, such as copper, iron, aluminum, stainless steel, etc.), and is arranged in the tubular lampshade 11. Therefore, the support board 13 can not only provide a heat dissipation effect, but also achieve a supporting effect to improve the structural strength of the tubular lampshade 11. In addition, the light source board 12 is also provided with a reflective coating to improve the light effect. In this way, the service life of the linear lighting device 1 can be effectively improved and the light effect can also be further improved to meet the needs of practical applications.

[0063] Thus, the linear lighting device 1 is very suitable for use in an inverse Fuji-shaped (mountain-shaped) lighting device to achieve high efficiency. The linear lighting device 1 can also be used in various other existing lighting devices.

[0064] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the linear lighting device with a single-side locking structure according to this embodiment should still be included in the patent scope of the present invention.

[0065] It is worth mentioning that the existing inverse Fuji-shaped lighting device still has many shortcomings to be improved. For example, the optical structure of the existing inverse Fuji-shaped lighting device will cause part of the light generated by its light source board to be lost, which greatly reduces the light efficiency of this lighting device. In addition, the lampshade and base of the existing inverse Fuji-shaped lighting device need to have a locking structure, which makes the structure of the lampshade and the base more complicated and easy to be damaged during transportation. In addition, the installation procedure of the existing inverse Fuji-shaped lighting device is more complicated, which requires more manpower, resulting in increased labor costs. In contrast, according to an embodiment of the utility model, the linear lighting device includes a tubular lampshade, a support plate, a light source plate, a base and a clamp. The tubular lampshade has a light-emitting portion and a shading portion. The light-emitting surface of the light-emitting portion is a curved surface. The bottom of the light-emitting portion has a lower opening, and the top of the shading portion has an upper opening and two grooves respectively arranged on both sides thereof. The bottom of the light-emitting portion is connected to the top of the shading portion. The support plate is arranged in the shading portion and adjacent to the upper opening. The light source board is arranged on one side of the support plate and faces the light-emitting portion. The base has a central groove, and the tubular lampshade is arranged on the central groove and closes the central groove. 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 respectively arranged on the two side walls. The two protrusions are respectively embedded in the two grooves, so that the clip and the shading part are fixed to each other. Through the above-mentioned single-sided fixing structure, the tubular lampshade can be fixed on the base without setting a locking structure, so that the structure of the tubular lampshade is simpler. In addition, the above-mentioned multiple clips are not exposed in the central groove, so that the structure of the base can also be simplified. The above-mentioned structural design makes the linear lighting device more convenient to transport and not easy to be damaged during transportation.

[0066] Furthermore, according to the embodiment of the utility model, the width of the bottom of the light-emitting portion of the tubular lampshade of the linear lighting device is greater than the width of the top of the light-shielding portion. Since 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 board can pass through the light-emitting portion without being blocked by the light-shielding portion. The above optical structure design can effectively reduce the light loss of the light source board, and greatly improve the light efficiency of the linear lighting device.

[0067] In addition, according to the embodiment of the utility model, the light source board and the power module and other electronic components of the linear lighting device are all arranged in the tubular lampshade. The above-mentioned tubular lampshade can be made of plastic, so that the tubular lampshade is a full plastic structure. The above-mentioned full plastic structure can effectively prevent the generation of reverse voltage, so that the safety of the linear lighting device can be greatly improved.

[0068] In addition, according to the embodiment of the utility model, the power module of the linear lighting device is disposed in its tubular lampshade, and the power module is not disposed in the power box, but can only be covered by a plastic film. The above-mentioned built-in power module design can not only effectively prevent the generation of reverse voltage to improve safety, but also greatly simplify the structure of the linear lighting device.

[0069] Furthermore, according to an embodiment of the present invention, the light source board of the linear lighting device is arranged on its support plate, and the support plate can be made of a high thermal conductivity material (various metals, such as copper, iron, aluminum, stainless steel, etc.) and is arranged in the tubular lampshade. Therefore, the support plate can not only provide a heat dissipation effect, but also achieve a supporting effect to improve the structural strength of the tubular lampshade. In addition, the light source board also has a reflective coating to improve the light effect. In this way, the service life of the linear lighting device can be effectively improved and the light effect can be further improved to meet the needs of practical applications. From the above, it can be seen that the linear lighting device with a single-sided locking structure according to the embodiment of the present invention can indeed achieve excellent technical effects.

[0070] See also Fig.10 , Fig.11 and Fig.12 , and please also refer to Figures 1 to 9 . Fig.10 It is a first schematic diagram of an installation procedure of a linear lighting device with a single-side locking structure according to a second embodiment of the utility model. Fig.11 for Fig.10 The first partial enlargement of the K1 area. Fig.12 for Fig.10 The second partial enlarged image of the K1 area. Fig.10 As shown, the bottom of the central recess Cs of the base 16 also has a mounting hole Gs, and the mounting hole Gs may be in the shape of a key hole.

[0071] like Fig.11 As shown, the user can first fix the fastener FX (such as a screw, nail or other similar component) on the ceiling. Then, the user can place the base 16 on the ceiling and align the mounting hole Gs with the fastener FX so that the head of the fastener FX enters one end of the mounting hole Gs. Then, the user can push the base 16 to move the base 16 toward the other end of the mounting hole Gs (as shown by arrow A1 in the figure).

[0072] Then, the base 16 moves toward the other end of the mounting hole Gs, so that the head of the locking member FX enters the other end of the mounting hole Gs. Fig.12 In this way, the user can fix the base 16 to the ceiling through the fastener 16, and then fix the two ends of the base 16 to the ceiling through other fasteners FX respectively.

[0073] Without the design of the mounting hole Gs, the user needs to first fix one end of the base 16 on the ceiling, but the other end of the base 16 needs to be held by another installer, which is very inconvenient for installation. With the design of the mounting hole Gs, the user can temporarily fix the base 16 on the ceiling, and then fix the two ends of the base 16 separately, so that the installation process is more convenient and labor can be saved.

[0074] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the linear lighting device with a single-side locking structure according to this embodiment should still be included in the patent scope of the present invention.

[0075] See also Fig.13 , Fig.14 , Fig.15 and Fig.16 , and please also refer to Figures 1 to 12 . Fig.13 It is a second schematic diagram of an installation procedure of a linear lighting device with a single-side locking structure according to a second embodiment of the utility model. Fig.14 for Fig.13 The first partial enlargement of the K2 area. Fig.15 for Fig.13 Second partial enlarged view of the K2 area. Fig.16 for Fig.13 The third partial enlarged image of the K2 area. Fig.13 As shown, after the base 16 is fixed on the ceiling, the user can temporarily hang the tubular lampshade 11 on the base 16 through the two safety ropes 18 to perform wiring operations.

[0076] like Fig.14 As shown, 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 fixed structure, and the fixed structure includes a column 151 and a fixed hook 152. One end of the fixed hook 152 is fixed to the bottom of the end cover 15, and the other end of the fixed hook 152 is spaced from the bottom of the end cover 15 to form an entrance Es. The column 151 is fixed to the bottom of the end cover 15 and is located on one side of the entrance Es.

[0077] The user can move the ball head 182 toward the direction of the space between the column 151 and the fixing hook 152 (as shown by arrow A2 in the figure).

[0078] like Fig.15 As shown, the user moves the ball head 182 toward the space between the column 151 and the fixing hook 152, so that the end of the rope 181 close to the ball head 182 enters the space between the column 151 and the fixing hook 152. Then, the user can pull the rope 181 toward the entrance Es, so that the rope 181 enters the central hole of the fixing hook 152 through the entrance Es.

[0079] like Fig.16 As shown, after the rope body 181 enters the central hole of the fixing hook 152 through the entrance Es, the rope body 181 can pass through the central hole of the fixing hook 152. In this way, the ball head 182 can be limited by the column 151 and the fixing hook 152 at the same time. In this way, the ball head 182 can be fixed on the fixing structure, and the other end of the rope body 181 is fixed to one of the two ends of the base 16.

[0080] Through the design of the fixing structure, the two end covers 15 can be firmly and quickly connected to the two ends of the base 16 through the two safety ropes 18. The user can temporarily hang the tubular lampshade 11 on the base 16 through the two safety ropes 18 to perform wiring operations. Therefore, the installation procedure of the linear lighting device 1 can be greatly simplified to reduce labor costs.

[0081] In addition, since the fixing structure is disposed on the two end covers 15 instead of the tubular lampshade 11, the structure of the tubular lampshade 11 can be further simplified.

[0082] When the installation process is completed, the two safety ropes 18 can also prevent the tubular lampshade 11 from falling. Therefore, the safety of the linear lighting device 1 can be further improved.

[0083] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the linear lighting device with a single-side locking structure according to this embodiment should still be included in the patent scope of the present invention.

[0084] See also Fig.17 and Fig.18 . Fig.17 It is a three-dimensional view of a linear lighting device with a single-side locking structure according to the third embodiment of the present invention. Fig.18 FIG. 1 is a perspective view of a linear lighting device with a single-side locking structure according to a fourth embodiment of the present invention. As shown in the figure, the tubular lampshade 11 can be connected to different bases (such as Figure 5 The base 16 shown, Fig.17 The base 16' and Fig.18 The base 16 ″) shown in the figure enables the linear lighting device 1 to have different appearances and functions.

[0085] Therefore, the tubular lampshade 11 can be sold separately as an independent product, which is more flexible in use. At the same time, the above structural design can also effectively reduce inventory, thereby reducing costs.

[0086] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the linear lighting device with a single-side locking structure according to this embodiment should still be included in the patent scope of the present invention.

[0087] In summary, according to an embodiment of the utility model, a linear lighting device includes a tubular lampshade, a support plate, a light source plate, a base and a clamp. The tubular lampshade has a light-emitting portion and a light-shielding portion. The light-emitting surface of the light-emitting portion is a curved surface. The bottom of the light-emitting portion has a lower opening, and the top of the light-shielding portion has an upper opening and two grooves respectively arranged on both sides thereof. The bottom of the light-emitting portion is connected to the top of the light-shielding portion. The support plate is arranged in the light-shielding portion and is adjacent to the upper opening. The light source plate is arranged on one side of the support plate and faces the light-emitting portion. The base has a central groove, and the tubular lampshade is arranged on the central groove and closes the central groove. The clamp 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 respectively arranged on the two side walls. The two protrusions are respectively embedded in the two grooves, so that the clamp and the light-shielding portion are fixed to each other. Through the above-mentioned single-sided fixing structure, the tubular lampshade can be fixed on the base without providing a locking structure, so that the structure of the tubular lampshade is more simplified. In addition, the plurality of clips are not exposed in the central groove, so that the structure of the base can be simplified. The above structural design makes the linear lighting device more convenient to transport and less likely to be damaged during transportation.

[0088] According to the embodiment of the utility model, the width of the bottom of the light-emitting portion of the tubular lampshade of the linear lighting device is greater than the width of the top of the light-shielding portion. Since 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 board can pass through the light-emitting portion without being blocked by the light-shielding portion. The above optical structure design can effectively reduce the light loss of the light source board, and greatly improve the light efficiency of the linear lighting device.

[0089] Furthermore, according to the embodiment of the utility model, the light source board and the power module and other electronic components of the linear lighting device are all arranged in the tubular lampshade. The above-mentioned tubular lampshade can be made of plastic, so that the tubular lampshade is a full plastic structure. The above-mentioned full plastic structure can effectively prevent the generation of reverse voltage, so that the safety of the linear lighting device can be greatly improved.

[0090] In addition, according to the embodiment of the utility model, the power module of the linear lighting device is disposed in its tubular lampshade, and the power module is not disposed in the power box, but can only be covered by a plastic film. The above-mentioned built-in power module design can not only effectively prevent the generation of reverse voltage to improve safety, but also greatly simplify the structure of the linear lighting device.

[0091] In addition, according to an embodiment of the utility model, the light source board of the linear lighting device is arranged on its support plate, and the support plate can be made of a high thermal conductivity material (various metals, such as copper, iron, aluminum, stainless steel, etc.) and is arranged in the tubular lampshade. Therefore, the support plate can not only provide a heat dissipation effect, but also achieve a supporting effect to improve the structural strength of the tubular lampshade. In addition, the light source board also has a reflective coating to improve the light effect. In this way, the service life of the linear lighting device can be effectively improved and the light effect can be further improved to meet the needs of practical applications.

[0092] Furthermore, according to an embodiment of the utility model, the linear lighting device further comprises two end caps and two safety ropes. The two end caps are respectively arranged at the two ends of the tubular lampshade and are respectively connected to the two ends of the base through the two safety ropes. Each end cap has a fixed structure. Each safety rope comprises a rope body and a ball head connected to one end of the rope body. The ball head is fixed to the fixed structure, and the other end of the rope body is fixed to one of the two ends of the base. The fixed structure comprises a column and a fixed hook. One end of the fixed hook is fixed to the bottom of the end cap, and the other end of the fixed hook is spaced from the bottom of the end cap to form an entrance. The column is fixed to the bottom of the end cap and is located on one side of the entrance. The rope body passes through the central hole of the fixed hook so that the ball head is limited by the column and the fixed hook at the same time. Through the design of the fixed structure, the two end caps can be firmly and quickly connected to the two ends of the base through the two safety ropes to prevent the tubular lampshade from falling. In addition, the user can also temporarily hang the tubular lampshade on the base through the two safety ropes to perform wiring operations. Therefore, the installation procedure of the linear lighting device can be greatly simplified to reduce labor costs. At the same time, the safety of the linear lighting device can also be further improved.

[0093] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structural or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
