Description

[Technical field]

[0001] The present invention relates to a lighting device, in particular to a linear lighting device with a counterbore fixing structure. [Background technology]

[0002] The inverted Fuji type (mountain type) lighting device has unique shape and lighting characteristics, and its main feature is the design of the triangular base or the inverted cone base. The above designs are advantageous for uniform distribution of light and efficient use of space, so they are widely applied in various buildings.

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

[0004] In addition, when installing a conventional inverted Fuji-type lighting device, the internal components are susceptible to interference from the fixing bolts, requiring the user to appropriately cut the fixing bolts, which is extremely inconvenient during installation and requires a relatively large amount of effort, resulting in increased labor costs. Summary of the Invention [Problem to be solved by the invention]

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a linear lighting device with a counterbore fixing structure. [Means for solving the problem]

[0006] According to an embodiment of the present invention, there is provided a linear lighting device with a counterbore fixing structure, including a tubular globe, a support plate, a light source substrate and a base. The tubular globe has a light emitting part and a light shielding part. The light emitting part includes a light emitting surface and two flat plates. The two flat plates are disposed on both sides of the light emitting surface. The light emitting surface is a curved surface. A lower opening is formed between the two flat plates, and the upper part of the light shielding part has an upper opening. The light emitting part is disposed in the light shielding part, and the width of the lower opening is larger than the width of the upper opening. The support plate is disposed in the light shielding part and adjacent to the upper opening. The light source substrate is disposed on one side of the support plate and faces the light emitting part. The base has a fixing hole, and the tubular globe is disposed on the base. The bottom of the light shielding part has a counterbore corresponding to the fixing hole, and the counterbore extends in a direction toward the support plate. Effect of the Invention

[0007] Based on the above, the linear lighting device with the countersunk hole fixing structure according to the embodiment of the present invention can have the following advantages: According to the embodiment of the present invention, the linear lighting device has a countersunk hole fixing structure. The fixing bolt passes through the corresponding fixing hole and enters the opening of the corresponding countersunk hole. The other end of the countersunk hole is closed, so that the fixing bolt does not contact the internal members of the light shielding part (the power supply module and other members). Therefore, the internal members of the light shielding part are not interfered with by the fixing bolt, and the user does not need to cut the fixing bolt. Therefore, the installation of the linear lighting device is more convenient, and the labor cost can be effectively reduced. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] In the following embodiments, the detailed features and advantages of the present invention are described, the contents of which are sufficient to enable those skilled in the art to understand the technical contents of the present invention and implement them accordingly, and the disclosure contents of this specification, the claims and drawings of the utility model registration can enable those skilled in the art to easily understand the objectives and advantages of the present invention.

[0010] Hereinafter, the embodiment of the lighting device with current self-balancing function of the present invention will be described with reference to the related drawings. For the sake of clarity and ease of description in the drawings, the dimensions and ratios of each member in the drawings may be exaggerated or reduced. In the following description and / or the claims, when a member is described as being "connected" or "coupled" to another member, it may be directly connected or coupled to the other member, or an intermediate member may be present. When a member is described as being "directly connected" or "directly coupled" to another member, there is no intermediate member, and other terms for describing the relationship between members or layers should be interpreted in the same manner. For ease of understanding, the same members in the following embodiments will be denoted and described with the same reference numerals.

[0011] Please refer to Fig. 1, Fig. 2 and Fig. 3. Fig. 1 is a perspective view of a linear lighting device with a counterbore fixing structure of the first embodiment of the present invention. Fig. 2 is a first cross-sectional view of a linear lighting device with a counterbore fixing structure of the first embodiment of the present invention (without a support plate, a light source board and a power module). Fig. 3 is a second cross-sectional view of a linear lighting device with a counterbore fixing structure of the first embodiment of the present invention (with a support plate, a light source board and a power module). Fig. 4 is a third cross-sectional view of a linear lighting device with a counterbore fixing structure of the first embodiment of the present invention. As shown in the figures, the linear lighting device 1 includes a tubular globe 11, a light source board 12, a support plate 13, a power module 14 and two end caps 15.

[0012] The tubular globe 11 has a light-emitting portion 111 and a light-shielding portion 112. The two end caps 15 are respectively installed at both ends of the tubular globe 11. In this embodiment, the tubular globe 11 is an all-plastic structure made of plastic (which may be various conventional plastic materials, such as PMMA, PC, etc., but is not limited thereto). The light-emitting portion 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 is formed with a lower opening PH1, and the bottom of the light-emitting portion 111 has an upper opening PH2. The light-shielding portion 112 has two grooves Rs installed on both sides thereof. The light-emitting portion 111 is installed in the light-shielding portion 112, and the flat plate FP protrudes on both sides of the light-shielding portion 112, making the cross section of the globe 11 mushroom-shaped. In addition, the width of the lower opening PH1 is larger 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 (W1×2) of the two flat plates FP. The all-plastic structure described above can prevent the occurrence of reverse voltage, and can greatly improve the safety of the linear lighting device 1. The light emitting part LS has a central part MP, two side parts LP, and two buffer parts BP. The central part MP is disposed between the two buffer parts BP. One side part LP is disposed on one side of one of the buffer parts BP. The other side part LP is disposed on one side of the other buffer part BP. The curvature of the side part LP is greater than that of the central part MP, and the curvature of the central part MP is greater than that of the buffer part BP. The sum of the curvature of the central part MP and the curvature of the two buffer parts BP is less than or equal to the curvature of any one of the side parts LP.

[0013] The support plate 13 is installed in the light-shielding part 112 and 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 respectively fixed to two inner walls of the light-shielding part 112. Each inner wall has an L-shaped hook part V1 and a position restriction plate V2. The position restriction plate V2 is installed above the L-shaped hook part V1. Two L-shaped hook parts V1 are embedded respectively on both sides of the support plate 13, and the two position restriction plates V2 provide a position restriction function and prevent the support plate 13 from being separated from the two L-shaped hook parts V1. The support plate 13 may be formed of a material with high thermal conductivity. This material may 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 function and increase the structural strength of the tubular globe 11.

[0014] The light source substrate 12 is disposed on one side of the support plate 13 and faces the light emitting portion 111. The light source substrate 12 may include a circuit board 121 and a plurality of light sources 122, and the plurality of light sources 122 are disposed on the circuit board 121. In this embodiment, the above-mentioned plurality of light sources 122 may be light emitting diodes (LEDs). In another embodiment, the light source substrate 12 may be replaced with other light emitting units (such as fluorescent lamps, light bulbs, etc.). The light source substrate 12 may further have a light reflective paint on it to provide a light reflective effect and improve light efficiency.

[0015] The power supply module 14 is installed on the other side of the support plate 13 and located within the light shielding portion 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 portion 112, and does not require a separate power supply case. The power supply module 14 may also be merely covered with a plastic film. In one embodiment, the power supply module 14 is a light emitting diode driver. In another embodiment, the power supply module 14 may be a driver for other conventional light sources. The above design of the built-in power supply module 14 not only improves the safety of the linear lighting device 1, but also greatly simplifies the structure of the linear lighting device 1.

[0016] As a result, the width L1 of the lower opening PH1 is greater than the width L2 of the upper opening PH2, so that most of the light emitted by the light source plate 12 can pass through the light-emitting part 111 and is not blocked by the light-shielding part 112. The above-mentioned 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. In addition, the curvature design of the light-emitting part LS optimizes the above-mentioned optical structure design, further making the emitted light uniform and shading the light.

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

[0018] The above components are the same as those in the above embodiment. Different from the above embodiment, 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 to close the central groove Cs, position the light-shielding part 112 in the central groove Cs, and expose the light-emitting part 111 from the central groove Cs. In addition, the base 16 may have knock-down holes Bs at both ends. When connecting multiple linear lighting devices 1 in series, the covers of the multiple knock-down holes Bs can be removed. Then, an electrical connection wire can pass through the knock-down holes Bs to electrically connect the multiple linear lighting devices 1.

[0020] The two clips 17 may be made of metal materials such as copper, iron, aluminum, and stainless steel. Each clip 17 is U-shaped and includes a bottom plate 171, two side walls 172, and two protrusions 173. The bottom plate 171 is fixed to the bottom of the central groove Cs, and the two protrusions 173 are respectively installed on the two side walls 172. Each clip 17 is not exposed to the central groove Cs. As described above, the light shielding part 112 has two grooves Rs respectively installed on both sides of the light shielding part 112, and the two protrusions 173 are respectively inserted into the two grooves Rs to fix the clip 17 and the light shielding part 112 to each other. In this way, the tubular globe 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 may only include one clip 17 or three or more clips 17. Due to the above-mentioned one-sided locking structure, the tubular globe 11 can be fixed to the base 16 without the need to install a fixing structure, which simplifies the structure of the tubular globe 11. In addition, the above-mentioned multiple clips 17 are not exposed to the central groove Cs, which further simplifies the structure of the base 16. Due to the above-mentioned structural design, the linear lighting device 1 is more convenient to transport and less likely to be damaged during transportation.

[0021] The two end caps 15 are provided at both ends of the tubular globe 11, respectively, and are connected to both ends of the base 16 via the two safety ropes 18. The two end caps 15 provide waterproof and dustproof effects, and improve 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 supply module 14 is connected to the electrical connection line 19, and the electrical connection line 19 is connected to the connection terminal 20 after passing through a connection hole. The connection hole is located near one end cap 15. This connection hole can be fitted with a seal ring SR (such as a rubber ring) to achieve waterproof and dustproof effects. The connection terminal 20 can be located on the rear surface of the tubular globe 11. In this embodiment, the electrical connection line 19 can be fixed to the rear part of the tubular globe 11 by a tape TP or other similar methods, but is not limited thereto.

[0023] As a result, the width L1 of the lower opening PH1 is greater than the width L2 of the upper opening PH2, so that most of the light emitted by the light source plate 12 can pass through the light-emitting portion 111 and is not blocked by the light-shielding portion 112. Through the above-mentioned 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.

[0024] In addition, electronic components such as the light source board 12 and the power module 14 of the linear lighting device 1 are installed inside the tubular globe 11. The above-mentioned tubular globe 11 may be made of plastic, making the tubular globe 11 an all-plastic structure. The above-mentioned all-plastic structure can effectively prevent the occurrence of reverse voltage, and greatly improve the safety of the linear lighting device 1.

[0025] In addition, the power supply module 14 of the linear lighting device 1 can be installed in the tubular globe 11, not installed in the power supply case, but only covered with a plastic film. The above-mentioned built-in power supply module design not only effectively prevents the occurrence of reverse voltage and improves safety, but also greatly simplifies the structure of the linear lighting device 1.

[0026] Furthermore, due to the one-sided fixing structure described above, the tubular globe 11 can be fixed to the base 16 without the need for a fixing structure, simplifying the structure of the tubular globe 11. In addition, the multiple clips 17 are not exposed to the central groove Cs, further simplifying the structure of the base 16. With the above structural design, the linear lighting device 1 is more convenient to transport and less likely to be damaged during transportation.

[0027] In addition, the light source substrate 12 of the linear lighting device 1 is installed on its support plate 13, which may be made of a highly thermally conductive material (such as various metals as copper, iron, aluminum, stainless steel, etc.) and is installed inside the tubular globe 11. Therefore, the support plate 13 not only provides a heat dissipation effect, but also achieves a supporting function and can increase the structural strength of the tubular globe 11. In addition, the light source substrate 12 further has a light reflective paint to increase the light efficiency. In this way, the service life of the linear lighting device 1 can be effectively extended and the light efficiency can be further improved, so as to meet the requirements of practical applications.

[0028] In this way, the linear lighting device 1 is suitable for application to an inverted Fuji type (mountain type) lighting device and achieves high performance. The linear lighting device 1 can also be applied to various other conventional lighting devices.

[0029] Please refer to Fig. 10, Fig. 11 and Fig. 12, and also refer to Fig. 1 to Fig. 9. Fig. 10 is an explanatory diagram of the installation process of a linear lighting device having a countersunk hole fixing structure according to a second embodiment of the present invention. Fig. 11 is a first partial enlarged view of the K1 area in Fig. 10. Fig. 12 is a second partial enlarged view of the K1 area in Fig. 10. As shown in Fig. 10, the bottom of the central groove Cs of the base 16 further has a mounting hole Gs, which may be in the shape of a keyhole.

[0030] As shown in Fig. 11, a user can first fix a fixing member FX (a screw, a nail, or other similar member) to a ceiling. Then, the user can place the base 16 on the ceiling, align the mounting hole Gs with the fixing member FX, and insert the head of the fixing member into one end of the mounting hole Gs. Then, the user can push the base 16 to move the base 16 in a direction toward the other end of the mounting hole Gs (arrow A1 in the figure).

[0031] 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 manner, the user can fix the base 16 to the ceiling via the fixing member 16, and fix both ends of the base 16 to the ceiling via other fixing members FX.

[0032] Without the design of the mounting holes Gs, the user must first fix one end of the base 16 to the ceiling, but the other end of the base 16 must be held by another installer's hand, making installation extremely inconvenient. With the design of the mounting holes Gs, the user can temporarily fix the base 16 to the ceiling and then fix both ends of the base 16, respectively, making the installation process more convenient and saving labor.

[0033] Please refer to FIG. 13 and FIG. 14, and also refer to FIG. 1 to FIG. 12. FIG. 13 is a perspective view of a linear lighting device with a counterbore fixing structure according to a third embodiment of the present invention. FIG. 14 is an explanatory diagram of an installation process of a linear lighting device with a counterbore fixing structure according to a third embodiment of the present invention. As shown in FIG. 13, the bottom of the light-shielding part 112 has four counterbore holes SH. The number of the counterbore holes SH is only an example and can be changed according to needs. One end of each counterbore hole SH is open, and the other end is closed. The other end of each counterbore hole SH extends in a direction toward the support plate 13 (see FIG. 3). In this embodiment, the counterbore holes SH are circular. In another embodiment, the counterbore holes SH may be elliptical, rectangular, rod-like or other shapes. The shape of the counterbore holes SH can be changed according to actual needs.

[0034] As shown in FIG. 14, the base 16 has four fixing holes LH, and the four countersunk holes SH correspond to the four fixing holes LH, respectively. The number of the fixing holes LH is merely an example, and can be changed according to actual needs. The linear lighting device 1 can be fixed to the ceiling board CL via four fixing bolts SF. Each fixing bolt SF passes through the corresponding fixing hole LH and enters the opening of the corresponding countersunk hole SH. Since the other end of the countersunk hole SH is closed, the fixing bolt SF does not come into contact with the internal members (power supply module 14 and other members) of the light shielding part 112. Therefore, the internal members of the light shielding part 112 are not interfered with by the fixing bolts SF, and the user does not need to cut the fixing bolts SF.

[0035] 15 is a perspective view of a linear lighting device with a countersunk hole fixing structure according to a fourth embodiment of the present invention, and is also shown in FIG. 1 to FIG. 12. As shown in the figure, in this embodiment, the countersunk hole SH' is elliptical, can correspond to multiple fixing holes LH at the same time, and can accommodate multiple fixing bolts SF.

[0036] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or variations made based on the linear lighting device with the countersunk hole fixing structure of this embodiment should still fall within the protection scope of the present invention.

[0037] In summary, according to the embodiment of the present invention, the linear lighting device 1 has a countersunk hole fixing structure. The fixing bolt SF passes through the corresponding fixing hole LH and enters the opening of the corresponding countersunk hole SH. The other end of the countersunk hole SH is closed, so that the fixing bolt SF does not contact the internal members of the light shielding part 112 (the power supply module 14 and other members). Therefore, the internal members of the light shielding part 112 are not interfered with by the fixing bolt SF, and the user does not need to cut the fixing bolt SF. Therefore, the installation of the linear lighting device 1 is made more convenient and the labor cost can be effectively reduced.

[0038] It should be noted that, although the above embodiments are described in this specification, they do not limit the scope of the utility model registration claims of the present invention. Therefore, based on the innovative concept of the present invention, the changes and modifications to the embodiments described in this specification, or the replacement of equivalent structures or equivalent processes using the contents of the specification and drawings of the present invention, and the direct or indirect application of the above technical solutions to other related technical fields are all within the scope of the utility model registration claims of the present invention.
