[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 incorporating the concealed intelligent module of the present invention, with reference to the relevant drawings. For clarity and ease of illustration, the dimensions and proportions of the components in the drawings may be exaggerated or reduced. In the following description and / or claims, where it is stated that a component is “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. Where it is stated that a component is “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 with a concealed intelligent module according to a first embodiment of the present invention. Figure 2 is a first cross-sectional view of a linear lighting device with a concealed intelligent module according to a first embodiment of the present invention (without support plate, light source substrate, and power supply module). Figure 3 is a second cross-sectional view of a linear lighting device with a concealed intelligent module according to a first embodiment of the present invention (with support plate, light source substrate, and power supply module). Figure 4 is a third cross-sectional view of a linear lighting device with a concealed intelligent module according to a first embodiment of the present invention. As shown in the figures, the linear lighting device 1 comprises a tubular globe 11, a light source substrate 12, a support plate 13, a power supply module 14, and two end covers 15.

[0012] The tubular glove 11 has a light-emitting part 111 and a light-shielding part 112. The two end caps 15 are respectively installed at both ends of the tubular glove 11. In this embodiment, the tubular glove 11 is an all-plastic structure formed of plastic (this material may be various conventional plastic materials, such as PMMA, PC, etc., but is not limited thereto). The light-emitting surface LS of the light-emitting part 111 is a curved surface. The bottom of the light-emitting part 111 has a lower opening, and the upper part of the light-shielding part 112 has an upper opening. The light-shielding part 112 has two grooves Rs respectively installed on both sides thereof. The bottom of the light-emitting part 111 is connected to the upper part of the light-shielding part 112. Also, the width L1 of the bottom of the light-emitting part 111 is larger than the width L2 of the upper part of the light-shielding part 112. With the above-described all-plastic structure, the generation of reverse voltage can be effectively prevented, and the safety of the linear lighting device 1 can be greatly improved.

[0013] The support plate 13 is installed in the light-shielding part 112 and 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 respectively fixed to the two inner walls of the light-shielding part 112. Each inner wall has an L-shaped hook part V1 and a position regulating plate V2. The position regulating plate V2 is installed above the L-shaped hook part V1. Two L-shaped hook parts V1 are respectively embedded on both sides of the support plate 13, and the two position regulating plates V2 provide a position regulating function to prevent the support plate 13 from detaching 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 further achieve a supporting effect and enhance the structural strength of the tubular glove 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 reflection paint on it, which can provide a light reflection 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 on 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 above 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 board 12 can pass through the light emitting part 111 and will not be blocked by the light shielding part 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 greatly improved.

[0017] Refer to Figures 5, 6, 7, 8, and 9, and also refer to Figures 1 to 4. Figure 5 is a perspective view of a linear lighting device equipped with a concealed intelligent module according to a second embodiment of the present invention. Figure 6 is an exploded view of a linear lighting device equipped with a concealed intelligent module according to a second embodiment of the present invention. Figure 7 is a side view of the base of a linear lighting device equipped with a concealed intelligent module according to a second embodiment of the present invention. Figure 8 is an explanatory diagram of the combination of the base and the tubular globe of a linear lighting device equipped with a concealed intelligent module according to a second embodiment of the present invention. Figure 9 is an explanatory diagram of the electrical connection lines of a linear lighting device equipped with a concealed intelligent module according to a second embodiment of the present invention. As shown in the figures, the linear lighting device 1 comprises a tubular globe 11, a light source substrate 12, a support plate 13, a power supply module 14, and two end covers 15.

[0018] Each of the above components is the same as in the above embodiment. The difference from the above embodiment is that in this example, the linear lighting device 1 further includes a base 16, two clips 17, and two safety ropes 18.

[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.

[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 (the outer surface of the light-shielding portion 112) 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, and 12, and also to Figures 1 to 9. Figure 10 is a first explanatory diagram of the installation process of a linear lighting device equipped with a concealed intelligent module according to a second embodiment of the present invention. Figure 11 is a first partial enlarged view of area K1 in Figure 10. Figure 12 is a second partial enlarged view of area K1 in Figure 10. As shown in Figure 10, the bottom of the central groove Cs of the base 16 further has mounting holes Gs, which may have the shape of keyholes.

[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] Refer to Figures 13, 14, 15, and 16. Figure 13 is an explanatory diagram of the end cover of a linear lighting device equipped with a concealed intelligent module according to a third embodiment of the present invention. Figure 14 is a first partial structural diagram of a linear lighting device equipped with a concealed intelligent module according to a third embodiment of the present invention. Figure 15 is a second partial structural diagram of a linear lighting device equipped with a concealed intelligent module according to a third embodiment of the present invention. Figure 16 is a cross-sectional view of a linear lighting device equipped with a concealed intelligent module according to a third embodiment of the present invention. As shown in the figures, the differences from the previously described embodiments are as follows: One of the two end covers 15 of the linear lighting device 1 includes an end cover body 151 and an end cover extension 152 connected to each other. The linear lighting device 1 also further includes a control circuit board 21 and a plurality of intelligent modules. These intelligent modules may include a sensor module 22, a communication module 23, and a switch module 24. The control circuit board 21 may include a controller. In one embodiment, the controller may be a microcontroller (CPU), a central processing unit (MCU), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other similar component. In one embodiment, the sensor module 22 may be a microwave sensor, an infrared sensor, or other similar component. In one embodiment, the communication module 23 may be a Bluetooth module, a ZigBee module, a WiFi module, or other similar component. In one embodiment, the switch module 24 may be a DIP switch, a button, a knob, or other similar component.

[0034] The end cover body 151 covers one end of the light-emitting section 111, and the end cover extension 152 covers one end of the light-shielding section 112 and extends toward the light-shielding section 112, forming a mounting space TS. The sensor module 22, communication module 23, and switch module 24 are all installed in the mounting space TS. Of these, the control circuit board 21 is installed in the mounting space TS and is electrically connected to the power supply module 14. The sensor module 22, communication module 23, and switch module 24 are installed on the control circuit board 21 and are electrically connected to the control circuit board 21. The bottom of the end cover extension 152 has an opening, exposing the switch module 24 from the bottom of the end cover extension 152.

[0035] As can be seen from the above, the control circuit board 21, sensing module 22, communication module 23, and switch module 24 are all installed within the end cover extension 152 and therefore do not affect the illumination of the light-emitting unit 11 (see Figure 15). The sensor module 22 can be used to detect moving objects and generate detection signals. The communication module 23 can be used to send and receive various signals. The switch module 24 can be used for group configuration. The above multiple intelligent modules can be used to perform different intelligent functions.

[0036] Since the control circuit board 21, sensor module 22, communication module 23, and switch module 24 are all installed within the end cover extension 152, the structural design of this hidden intelligent module does not obstruct the light rays emitted by the linear lighting device 1, and therefore the linear lighting device can still achieve a good lighting effect.

[0037] 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 with the concealed intelligent module of these embodiments should still be within the scope of protection of the present invention.

[0038] In summary, according to embodiments of the present invention, the linear lighting device has a structural design of a concealed intelligent module. Because this concealed intelligent module's structural design does not obstruct the light rays emitted by the linear lighting device, the linear lighting device can still achieve a good lighting effect. Furthermore, these intelligent modules can perform different intelligent functions and can meet the needs of different intelligent applications.

[0039] 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.
