Background Art

[0002] As one aspect of an LED lighting device, there is known one in which the light source in a fluorescent lamp having a straight tubular fluorescent tube is replaced with an LED. In this case, a power control circuit for converting an AC voltage into a DC voltage is required. A proposal has been made to provide a housing portion incorporating the power control circuit at one end of a lighting portion having an appearance and form of a straight tubular fluorescent tube, and to attach this housing portion to one socket portion of the straight tubular fluorescent tube. In recent years, an LED lighting device in which functions such as a sensor and a camera are incorporated into the housing portion of such an LED lighting device has been proposed.

[0003] For example, Patent Document 1 proposes an LED lighting device in which a housing portion accommodating a sensor, a camera, etc. is rotatable with respect to a lighting portion.

[0004] Patent Document 2 proposes an LED lighting system that analyzes external information acquired by an LED lighting device and generates notification information based on the analysis result.

Problems to be Solved by the Invention

[0007] When the LED lighting device proposed in Patent Document 1 is attached to the socket of a straight tubular fluorescent lamp provided in the passenger compartment of a railway vehicle, for example, if the housing part is installed at a position accessible to passengers, the rotation angle of the housing part with respect to the lighting part may be changed due to mischief or the like. Therefore, in the LED lighting device of Patent Document 1, a pair of engaging convex portions provided at both ends of the inner peripheral surface of the intermediate connecting portion constituting the rotation guide portion are engaged with any one of a plurality of engaging concave portions provided along the circumferential direction at both axial ends of the resin wall portion constituting the housing part. As a result, the rotation angle of the housing part with respect to the lighting part is set in advance, and the rotation angle cannot be adjusted unless the housing part is removed.

[0008] In the LED lighting systems proposed in Patent Document 2 and Patent Document 3, the housing part of the LED lighting device constituting the system cannot be rotated with respect to the lighting part.

[0014] Hereinafter, an example of an embodiment of the present invention will be described with reference to the accompanying drawings.

[0015] [LED Lighting Device] The LED lighting device 1 of the present embodiment is attached to two sockets of a straight tube fluorescent lamp having an existing straight tube fluorescent tube installed near the ceiling of a railway vehicle, a building, or the like.

[0016] As shown in FIGS. 1 to 3, the LED lighting device 1 includes a lighting unit 2 that is a lighting portion for emitting light of an LED, a functional unit 7 having functions other than lighting such as a camera, a chassis portion 12 in which the functional unit 7 is disposed, a joint portion 4 to which the lighting unit 2 and the chassis portion 12 are respectively connected, and a housing portion 3 that houses the joint portion 4, the functional unit 7, and the chassis portion 12 and is attached to the joint portion 4 so as to be rotatable in the circumferential direction about the axis of the joint portion 4.

[0017] (Lighting Unit) The lighting unit 2 includes a straight tube cover portion 2a including a light-transmissive portion for emitting the light of the LED provided inside to the outside, an LED support portion (not shown) that extends from one end side to the other end side in the horizontal axis direction of the straight tube cover portion 2a and is disposed inside the straight tube cover portion 2a and to which the LED is installed, and a first base portion 5 that is connected to be powered from one socket of the straight tube fluorescent lamp and is fixed to one end portion of the LED support portion.

[0018] The straight tube cover portion 2a is a light-transmissive straight tube portion in which the outer peripheral surface of a straight tube glass member is covered with a scattering prevention film such as PET (polyethylene terephthalate). Note that the straight tube cover portion 2a is not limited to a glass member and may be made of other materials such as polycarbonate as long as it is a member including a light-transmissive portion for emitting the light of the LED to the outside.

[0019] In the straight tubular cover portion 2a, there is accommodated a power control circuit portion (not shown) in a box, which includes an LED support portion with a plurality of LEDs (not shown) installed inside, and a circuit that converts an AC voltage (for example, AC100V - 254V) supplied from one socket of the straight tubular fluorescent lamp into a predetermined DC voltage.

[0020] The power control circuit portion is electrically connected to the first base portion 5 and the plurality of LEDs, and is also electrically connected to the functional portion 7 via a connector (not shown).

[0021] The power control circuit portion converts the power supplied from the first base portion 5 into a predetermined DC voltage for the plurality of LEDs and a predetermined DC voltage (for example, DC5V) for the functional portion 7, and supplies it.

[0022] The power control circuit portion is, for example, such that a connector connected to the functional portion 7 can be drawn out of the straight tubular cover portion 2a via an electric wire.

[0023] The LED support portion is, for example, a cylindrical member made of an aluminum material with excellent heat dissipation properties, and is connected and fixed to one - end side fixing portion 4a of the joint portion 4 shown in FIG. 4.

[0024] Also, the LED support portion is connected and fixed to the first base portion 5 and the one - end side fixing portion 4a of the joint portion 4, enabling it to be linearly connected and fixed along the horizontal axis direction including the joint portion 4 which serves as the rotation axis of the housing portion 3, from the first base portion 5 which is one end side of the LED lighting device 1 to the second base portion 6 which is the other end side.

[0025] The first base portion 5 is connected to one socket of the straight tubular fluorescent lamp. The first base portion 5 has a base body 5a which is a portion fixed to one end portion of the LED support portion, and two pins 5b which are electrical connection portions, and the two pins 5b are shaped to be attachable to the socket of the straight tubular fluorescent lamp.

[0026] The base body 5a is formed with an insertion hole (not shown) through which two pins 5b are inserted, and two screw insertion holes (not shown) through which screws for screwing and fixing one end of the LED support portion are inserted.

[0027] (Second base portion) The second base portion 6 has a base body 6a which is a portion fixed to the other end side fixing portion 4b of the joint portion 4, and two pins 6b. The two pins 6b are shaped so as to be attachable to the socket of a straight tube fluorescent lamp. In this embodiment, since the first base portion 5 serves as a power supply, the second base portion 6 is a dummy terminal.

[0028] (Joint portion) As shown in FIG. 4, the joint portion 4 has an end side fixing portion 4a which is a portion for fixing the other end portion of the LED support portion at one end side, and an other end side fixing portion 4b which is a portion for fixing the second base portion 6 connected to the other socket of the straight tube fluorescent lamp at the other end side, and an intermediate connecting portion 4c which connects between the end side fixing portion 4a and the other end side fixing portion 4b and has a notch portion formed with an arcuate cross section in a part of the cylinder so as to leave a ceiling side region.

[0029] The end side fixing portion 4a has a fitting portion 4e fitted into the cylindrical inner space of the LED support portion, an end side contact surface 4f contacting the end surface of the LED support portion, and a screw hole 4g for screwing and fixing to the LED support portion.

[0030] The end side fixing portion 4a is screwed and fixed to the LED support portion in a state where the fitting portion 4e is fitted into the cylindrical inner space of the LED support portion, a screw is inserted into the screw hole 4g from the other end side in the direction of the one end side, and the end surface of the LED support portion is abutted against the end side contact surface 4f. An opening 4h for drawing out the power line drawn from the lighting portion 2 to the inside is formed in the end side fixing portion 4a.

[0031] The intermediate connecting portion 4c is a portion connecting between the end side fixing portion 4a and the other end side fixing portion 4b, and a notch portion 4d having an arcuate cross section is formed in a part of the cylinder so as to leave a ceiling side region.

[0032] As shown in FIG. 4, a pair of engaging protrusions 4l that engage with engaging recesses 13g of a cylindrical body 13 that constitutes a chassis portion 12 described later are formed at both end portions of the inner peripheral surface of the intermediate connecting portion 4c.

[0033] The pair of engaging protrusions 4l are formed at the same positions in the circumferential direction of the intermediate connecting portion 4c, that is, at positions facing each other in the horizontal axis direction of the joint portion 4. By each engaging with the engaging recess 13g of the cylindrical body 13, the cylindrical body 13 is fixed to the intermediate connecting portion 4c as shown in FIG. 10(a).

[0034] The LED lighting device 1 is configured in a substantially integral straight tubular shape from the first base portion 5 to the second base portion 6 because the end portion of the LED support portion of the lighting portion 2 is connected and fixed to one end side of the joint portion 4 and the base body 6a of the second base portion 6 is fixed to the other end side. Therefore, it has rigidity from the first base portion 5 to the second base portion 6 and is supported and fixed between both sockets of a straight tubular fluorescent lamp.

[0035] (Functional unit) As shown in FIG. 3, the functional unit 7 includes a first circuit board 15 and a second circuit board 25 on which a control circuit for executing a camera function and related functions is formed, and a camera module 24 including the second circuit board 25.

[0036] On the first circuit board 15, a connector (not shown) that is a connection portion for power supplied through the lighting portion 2, a USB interface connector 17 (see FIG. 11) that is a portion for connecting a USB cable, an interface slot 18 (see FIG. 11) as a storage portion using a memory card such as a micro SD card as a storage medium 19, a communication module (not shown) as a wireless communication portion, a connector (not shown) connected to the camera module 24, etc. are mounted.

[0037] The USB interface connector 17 is wired-connected to a USB cable 50 as shown in FIG. 11, communicates with a client terminal 48 described later, and acquires various parameters for controlling the functions of the functional unit 7.

[0038] The interface slot 18 uses a memory card as a storage medium 19 to store videos, still images captured by the camera module 24, and information acquired by sensors that implement various other functions.

[0039] In this embodiment, during normal times, shooting information and the like are stored in the memory card, and when necessary, data such as shooting information can be directly extracted via wireless communication.

[0040] The communication module employs a communication system using a fourth-generation mobile communication system capable of stable communication even inside a mobile body, such as a communication method based on LTE (registered trademark), or a communication system using a communication method based on WiFi (registered trademark). In addition, a communication module using a fifth-generation mobile communication system as the communication method, or a communication module having both communication function limitations and switching functions of LTE and WiFi and capable of switching between the communication methods of LTE and WiFi can also be used.

[0041] The communication module is connected to antennas 21A to 21D mounted on the first circuit board 15 via a chassis portion 12 and a holding member 20 shown in FIGS. 3, 5, and 12 described later.

[0042] In this embodiment, the antennas 21A to 21D are film-shaped antennas, and the communication module can transmit and receive radio signals through these antennas 21A to 21D.

[0043] Also, a pilot lamp 23 as shown in FIG. 5 is mounted on the first circuit board 15 via the chassis portion 12. The pilot lamp 23 displays various execution states of the functional unit 7 outside the housing portion 3.

[0044] The first circuit board 15 having such a configuration is installed in the chassis portion 12 and is fixed by screwing with screws 33A and 33B shown in FIG. 3(b).

[0045] The second circuit board 25 constitutes a camera module 24 by mounting a camera unit 27 including a lens of the camera and a CMOS image sensor or the like. In this embodiment, a wide-angle fisheye lens with a maximum viewing angle of 180 degrees is adopted for the lens of the camera. Further, the camera unit 27 has functions such as a pan-tilt-zoom function, and functions for processing such as distortion correction and trimming of the captured video.

[0046] The first circuit board 15 and the second circuit board 25 are connected by a connector via a wiring cable 26 drawn out from the second circuit board 25. Further, the second circuit board 25 is installed in the chassis portion 12, and a holding member 20 which is a holder unit shown in FIG. 12 is mounted thereon, and screws 33B and 33C shown in FIG. 3(b) are inserted into screw holes 20b and 20c shown in FIG. 12 and fixed by screwing.

[0047] In addition, a plurality of function expansion slots 28 are provided on the second circuit board 25. The function expansion slots 28 are connectors to which modules having functions other than the camera module 24 can be connected, for example, a microphone for acquiring external sound, a speaker for outputting sound externally, a module for adjusting dimming and color adjustment of an LED, a module for detecting smoke, a module for acquiring an external infrared image, a module for measuring external temperature and humidity, a module for detecting components of air such as carbon dioxide and formaldehyde, a module for detecting 3D acceleration, a module for push-notifying various information to an external communication terminal, and the like.

[0048] The plurality of function expansion slots 28 are arranged side by side, and it is possible to easily replace modules with functions according to the requirements of the changing market.

[0049] In this embodiment, as shown in FIG. 13, four function expansion slots 28 are provided on the second circuit board 25, and a microphone 29, a smoke sensor 30, a temperature and humidity sensor 31, and a thermosensor 32 are arranged in each function expansion slot 28. As shown in FIG. 5, the speaker 22 is mounted on the first circuit board 15 via the chassis portion 12.

[0050] (Chassis section) The chassis section 12 is provided with a functional section 7, is housed in a space including a notch 4d on the inner surface side of the intermediate connection section 4c of the joint section 4, and a part thereof is fixed to the inner surface side of the joint section 4 and the inside of the housing section 3. Using the part fixed to the inner surface of the intermediate connection section 4c with respect to the joint section 4 as a support portion, it has a rotation function that can rotate in the circumferential direction around a horizontal axis extending from one socket of the straight tubular fluorescent lamp toward the other socket.

[0051] In the present embodiment, as shown in FIG. 5, the chassis section 12 has a chassis main body 12a formed in a shape necessary for providing the functional section 7. Further, the chassis section 12 includes one-end-side cylindrical portions 12b and the other-end-side cylindrical portions 12c formed at both ends of the chassis main body 12a (hereinafter, the one-end-side cylindrical portion and the other-end-side cylindrical portion may be collectively referred to as a "cylindrical portion"), cylindrical bodies 13 attached to the cylindrical portions 12b and 12c, and a rotation adjustment member 14 disposed between the cylindrical portions 12b and 12c and the cylindrical bodies 13, and has a rotation mechanism.

[0052] The ceiling-side portion of the chassis main body 12a is formed to be curved in an arc shape along the inner peripheral surface of the intermediate connection section 4c.

[0053] As shown in FIGS. 6(b) and 6(c), the one-end-side cylindrical portion 12b has an opening at one end, a bottom portion 12d at the other end, and a protrusion 12e protruding from the bottom portion 12d toward the opening. Further, two claw portions 12f, 12f extending in the radial direction are formed at the top of the protrusion 12e.

[0054] As shown in FIGS. 6(a) and 6(c), the other-end-side cylindrical portion 12c has an opening at the other end, a bottom portion 12d at one end, and a protrusion 12e protruding from the bottom portion 12d toward the opening. Further, two claw portions 12f, 12f extending in the radial direction are formed at the top of the protrusion 12e.

[0055] As shown in FIGS. 7 and 8, the cylindrical body 13 has a hollow shape with openings at one end and the other end, and has a cylindrical outer peripheral wall 13a that is a reduced-diameter outer peripheral wall compared to the cylindrical inner peripheral wall 12g which is the inner peripheral wall of the cylindrical portions 12b and 12c, a flange portion 13c that is a larger-diameter portion than the cylindrical outer peripheral wall 13a, and a bottom reduced-diameter portion 13d that is a reduced-diameter portion compared to the cylindrical inner peripheral wall 13b which is the inner peripheral wall.

[0056] On the cylindrical outer peripheral wall 13a, a stepped portion 13f that slopes in the direction from the flange portion 13c to the bottom reduced-diameter portion 13d is formed. As shown in FIG. 7(c), the rotation adjustment member 14 is held on this stepped portion 13f.

[0057] On the outer peripheral surface of the flange portion 13c, engaging concave portions 13g that engage with a pair of engaging protrusions 4l formed at both ends of the inner peripheral surface of the intermediate connecting portion 4c of the joint portion 4 are formed.

[0058] In the bottom reduced-diameter portion 13d, a groove portion 13e having a shape corresponding to the shape of the claw portions 12f of the cylindrical portions 12b and 12c is formed.

[0059] The rotation adjustment member 14 adjusts the rotation angle of the chassis portion 12 with respect to the joint portion 4 in the circumferential direction about the horizontal axis. In the present embodiment, an elastic O-ring having an annular shape is used as the rotation adjustment member 14. The rotation adjustment member 14 is attached to and held on the stepped portion 13f formed on the cylindrical outer peripheral wall 13a of the cylindrical body as described above.

[0060] As shown in Fig. 8, the cylindrical body 13 is attached to the cylindrical portions 12b and 12c. In this embodiment, the cylindrical body 13 is inserted into the cylindrical portions 12b and 12c such that the groove portion 13e of the cylindrical body 13 passes through the claw portions 12f of the cylindrical portions 12b and 12c (see Figs. 8(a) and (b)). After insertion, the cylindrical body 13 is rotated so that it cannot come out of the cylindrical portions 12b and 12c, and the bottom diameter-reduced portion 13d is locked between the claw portion 12f and the bottom portion 12 (see Figs. 8(c) and 9). From this state, as shown in Fig. 10(a), the cylindrical body 13 is fixed to the joint portion 4 by fitting a pair of engaging protrusions 4l formed at both ends of the inner peripheral surface of the intermediate connecting portion 4c of the joint portion 4 into the engaging concave portions 13g formed in the flange portion 13c of the cylindrical body 13.

[0061] In this state, the rotation adjustment member 14 is disposed between the inner peripheral wall 12g of the cylindrical portion of the cylindrical portions 12b and 12c and the outer peripheral wall 13a of the cylindrical body 13. By utilizing the resistance due to the frictional force of the rotation adjustment member 14 against the cylindrical portions 12b and 12c and the cylindrical body 13, the chassis portion 12 can be rotated circumferentially about a horizontal axis extending from one end side to the other end side of the joint portion 4 with respect to the joint portion 4 and the cylindrical body 13. In this embodiment, as shown in Figs. 10(b) and (c), the chassis portion 12 can be adjusted and held at an arbitrary angle within a range of 45 degrees in the circumferential direction about a horizontal axis extending from one end side to the other end side of the joint portion 4.

[0062] (Housing portion) The housing portion 3 is formed of a flame-retardant resin and is a portion that houses the chassis portion 12 and the joint portion 4 in which the functional portion 7 is provided and fixes a part of the chassis portion 12, and has a circular cross-sectional portion or an arc-shaped cross-sectional portion along the outer peripheral surface of the ceiling-side region of the joint portion 4. The housing portion 3 is attached to the outer peripheral surface so as to be rotatable in the circumferential direction about a horizontal axis extending from one socket of the straight tubular fluorescent lamp to the other socket together with the chassis portion 12 in which the functional portion 7 is provided, with the circular cross-sectional portion or the arc-shaped cross-sectional portion as a support portion for the joint portion 4.

[0063] In this embodiment, as shown in FIG. 3, a front cover 8 having an arcuate cross-sectional portion, a rear cover 9, a bottom cover 10, and an interface cover 11 are fixed to a chassis portion 12 to constitute a single housing portion 3.

[0064] In the form shown in FIG. 3, the arcuate cross-sectional portions of the front cover 8 and the rear cover 9 are portions along the outer peripheral surface of the joint portion 4 so that the housing portion 3 is supported rotatably in the circumferential direction about the axis of the joint portion 4.

[0065] With the chassis portion 12 in which the functional portion 7 and the holding member 20 are disposed in the space including the notch portion 4d on the inner surface side of the intermediate connecting portion 4c of the joint portion 4 being accommodated, these are sandwiched between the front cover 8 and the rear cover 9. A screw 33D is inserted through the screw hole 8a of the front cover 8, the screw hole 12h of the chassis portion 12, and the screw hole 20a of the holding member 20, and the screw 33D is screwed into the nut portion 9a of the rear cover 9 to fix the chassis portion 12 to the inner surface sides of the front cover 8 and the rear cover 9. Further, the bottom cover 10 is fitted to the bottom surface side of the chassis portion 12, a screw 33E is inserted through the screw hole 10a of the bottom cover 10, and the screw 33E is screwed into a nut portion (not shown) formed at the bottom of the chassis portion 12 to fix the chassis portion 12 to the inner surface side of the bottom cover 10. Furthermore, the interface cover 11 is attached so as to cover the bottom cover 10.

[0066] By attaching the housing portion 3 in this manner, using the resistance due to the frictional force of the cylindrical portions 12b, 12c of the rotation adjustment member 14 and the cylindrical body 13, the housing portion 3 and the chassis portion 12 fixed to the inner surface side of the housing portion 3 can be rotated in the circumferential direction about the axis of the joint portion 4 with respect to the joint portion 4 and the cylindrical body 13.

[0067] Therefore, according to the LED lighting device 1 of this embodiment, the rotation angle of the camera module 24 and various sensors that exhibit other functions can be easily adjusted to a desired angle without removing the housing portion 3.

[0068] In this embodiment, as described above, as the rotation mechanism of the chassis portion 12, a rotation adjustment member 14 is disposed between the inner peripheral wall 12g of the cylindrical portions 12b and 12c and the outer peripheral wall 13a of the cylindrical body 13, and the cylindrical body 13 is fixed to the joint portion 4. However, for example, the structure described below may be adopted.

[0069] In the cylindrical body 13 shown in FIG. 8, a cylindrical inner peripheral wall having a diameter larger than the outer peripheral wall of the cylindrical portions 12b and 12c, which is the outer peripheral wall of the cylindrical portions, is formed. Further, a bottom portion is formed, and a protrusion portion that protrudes from the bottom portion to the opening portion is formed. Further, at the top of the protrusion portion, a claw portion extending in the radial direction is formed. That is, a cylindrical body 13 having the same shape as the cylindrical portions 12b and 12c shown in FIG. 8 is formed.

[0070] In the cylindrical portions 12b and 12c shown in FIG. 8, a hollow shape with both ends open is formed. Further, a bottom diameter-reduced portion having a diameter smaller than the inner peripheral wall 12g of the cylindrical portion, which is the inner peripheral wall, is formed. Further, in the bottom diameter-reduced portion, a groove portion having a shape corresponding to the shape of the claw portion of the cylindrical body 13 described in the previous paragraph is formed. Further, on the outer peripheral wall of the cylindrical portion, which is the outer peripheral wall, a stepped portion that steps down in the direction of the bottom diameter-reduced portion is formed. That is, a cylindrical portion having the same shape as the shape excluding the flange portion 13c of the cylindrical body 13 shown in FIG. 8 is formed. Therefore, the rotation adjustment member 14 is attached and held to the stepped portion formed on the outer peripheral wall of the cylindrical portions 12b and 12c, and is disposed between the outer peripheral wall of the cylindrical portions 12b and 12c and the inner peripheral wall of the cylindrical body 13.

[0071] In FIG. 4, instead of the engaging protrusions 4l formed at both ends of the inner peripheral surface of the intermediate connecting portion 4c, a pair of engaging recesses are formed.

[0072] In FIG. 7, instead of the engaging recess 13g formed on the outer peripheral surface of the flange portion 13c, an engaging protrusion is formed.
