[0008] The first embodiment will be described below with reference to FIGS.

[0009] 1 to 5 show a lighting device 10. The lighting device 10 is a camera-equipped downlight that has both a lighting function and a camera function. The lighting device 10 is installed by embedding it into an embedding hole provided in an installation surface, such as a ceiling board.

[0010] The lighting device 10 includes a cylindrical housing 11, a light source 12 which is a light source unit disposed in the center of the housing 11, and a camera unit 13 which is disposed radially adjacent to the light source 12 on the periphery of the housing 11, with the light source 12 and the camera unit 13 being disposed within the same housing 11. The housing 11 of the first embodiment has an open-top fixture structure.

[0011] The housing 11 includes a decorative frame 16, which is the main body of the fixture, and a light source holder 17 disposed on the decorative frame 16. A plurality of mounting springs 18 are attached to the periphery of the decorative frame 16.

[0012] Decorative frame 16 is made of metal such as aluminum die-cast or resin. Decorative frame 16 is formed in a cylindrical shape centered on an imaginary center line in the vertical direction, and is provided with a tubular light source insertion portion 19 at the center, through which light source 12 is inserted, and a cylindrical reflective surface portion 20 that expands downward from the periphery of light source insertion portion 19. A tubular outer periphery 21 that is inserted into a recessed hole in the ceiling board protrudes upward from the lower side of reflective surface portion 20, and an edge portion 22 that is located on the underside of the ceiling board protrudes in the outer diameter direction.

[0013] The decorative frame 16 has a camera housing section 23 formed by a vertically penetrating opening in a portion of the reflective surface section 20, which houses the camera section 13. The camera housing section 23 has an inner peripheral section 24 formed in an arc shape along the lower part of the outer peripheral section 21, and side wall sections 25 provided between both circumferential ends of the inner peripheral section 24 and the outer peripheral section 21, and a camera housing space 26 formed by a vertically penetrating opening and which houses the camera section 13 is formed between the inner peripheral section 24, the side wall sections 25 on both sides, and the outer peripheral section 21. At least the inner peripheral section 24 of the camera housing section 23 is configured as a partition section 27 arranged between the light source 12 and the camera section 13.

[0014] The multiple mounting springs 18 are attached to the outer periphery 21 of the decorative frame 16, and when the lighting device 10 is installed, they are inserted into the embedding hole while being elastically deformed upward, and then they elastically expand sideways to engage with the upper side of the ceiling board, sandwiching the ceiling board between them and the edge 22 of the decorative frame 16, and attaching the lighting device 10 to the ceiling board.

[0015] The light source holder 17 is made of, for example, metal, has a cylindrical shape that opens downward, and is fixed onto the light source insertion portion 19 of the decorative frame 16. The light source holder 17 is provided with openings 28 at multiple locations in the circumferential direction, extending from the top surface to the side surface. A plurality of mounting portions 29 protrude from the inner periphery of the light source holder 17, to which the light sources 12 are detachably attached. The light source insertion portions 19 of the decorative frame 16 and the light source holder 17 are configured as a light source accommodating portion 30 that forms a light source accommodating space that accommodates the light source 12.

[0016] The light source 12 is cylindrical and detachably (replaceably) attached to the light source holder 17 through the light source insertion portion 19 of the decorative frame 16. The light source 12 includes a lower light source unit 32 and a heat dissipation unit 33 disposed above the light source unit 32. The light source unit 32 includes a light source module 34, which includes a light-emitting element such as an LED or an organic EL mounted on a substrate, and a translucent cover 35 that covers the light source module 34. The light source module 34 is thermally connected to the lower surface of the heat dissipation unit 33. A plurality of insertion grooves 36 are formed on the circumferential surface of the heat dissipation unit 33 along the insertion direction into the housing 11, and an attachment groove 37 is formed from the lower end of the insertion grooves 36 toward one side in the circumferential direction. The heat dissipation unit 33 is made of metal such as aluminum die-cast, and a plurality of heat dissipation fins 39 protrude from the upper portion of a base 38 to which the light source module 34 is attached. A light source connector 40 is disposed on the heat dissipation unit 33 and is electrically connected to the light source module 34 via wiring. Then, by aligning each insertion / removal groove 36 with the position of each mounting portion 29, and inserting the light source 12 into the light source holder 17 and then rotating it, each mounting groove 37 engages with each mounting portion 29, and the light source 12 is detachably attached to the light source holder 17. Note that the light source 12 may not be detachable from the housing 11, but may be provided integrally with the housing 11.

[0017] 1 to 6 show camera section 13. Camera section 13 includes camera body 43, camera case 44 that houses camera body 43, and holding member 45 that holds camera body 43 within camera case 44. Camera section 13 is attached to housing 11 by attachment member 46 so that the angle can be adjusted. Camera section 13 and attachment member 46 form a camera unit that is placed in housing 11.

[0018] The camera body 43 has an imaging unit 48 having an imaging element disposed inside a cylindrical main body 47, a lens 49 that forms an image of a subject on the imaging unit 48 disposed at the front end of the main body 47, and a camera cable 50 electrically connected to the imaging unit 48 extending to the rear end of the main body 47. The imaging unit 48 is positioned below the heat dissipation unit 33 of the light source 12 (and further below the light emitting element of the light source unit 32).

[0019] The camera case 44 is provided in a rectangular cylindrical shape, with an open top surface to allow the camera body 43 to be inserted, and a window hole 51 formed in the bottom surface to face the lens 49 of the camera body 43 .

[0020] The holding member 45 is formed with a generally U-shaped cross section, with leg portions 53 bent downward from both sides of an intermediate portion 52. A holding hole 54 that holds the rear end side of the camera body 43 is formed in the intermediate portion 52, and the legs 53 on both sides are arranged on the outer surfaces of both sides of the camera case 44 and are attached to the camera case 44 with screws 55 that are inserted from the outside of each leg 53 and screwed into the camera case 44. One of the screws 55 is inserted through the mounting member 46 and the leg portion 53 and screwed into the camera case 44, and the central axis of this one screw 55 serves as an angle adjustment axis 56, which is a fulcrum around which the camera body 43 rotates relative to the mounting member 46 to adjust the angle.

[0021] The mounting member 46 is formed in a generally L-shape and has a fixing portion 57 that is fixed to the upper surface of the light source holder 17 by screws, and a support portion 58 that is bent downward from the tip of the fixing portion 57 and supports the camera body 43. A cable insertion hole 59 through which the camera cable 50 is inserted is formed in the fixing portion 57. The support portion 58 has a screw insertion hole 60 through which the screw 55 is inserted, and an arc-shaped elongated hole 61 centered on the screw insertion hole 60 above the screw insertion hole 60. An adjustment screw 62 that is inserted through the elongated hole 61 is screwed into the leg portion 53 of the holding member 45.

[0022] The camera unit 13 can rotate together with an adjustment screw 62 around an angle adjustment axis 56, which is a screw 55, relative to the mounting member 46, and the angle of the shooting direction can be adjusted within a range in which the adjustment screw 62 abuts against one end or the other end of the long hole 61 and rotation is restricted.

[0023] Camera unit 13 can rotate around angle adjustment shaft 56, which faces in the radial direction (radial direction) from the center (center line) of housing 11, in a direction perpendicular to the radial direction of housing 11 (a tangential direction to the circumferential direction of housing 11), making it possible to adjust the shooting direction. Silicon washers, through which adjustment screws 62 are inserted, are interposed between camera case 44 and mounting member 46 and between mounting member 46 and adjustment screws 62, making it possible to change the angle of camera unit 13 even when adjustment screws 62 are tightened.

[0024] 3, a power supply unit 64 is connected to the light source 12, and a camera drive unit 65 is connected to the camera section 13. The power supply unit 64 and the camera drive unit 65 are inserted through the recessed holes and placed on the ceiling board when the lighting device 10 is installed. The power supply unit 64 and the camera drive unit 65 may be provided integrally.

[0025] The power supply unit 64 is connected to the light source 12 via a power cable connected to the light source connector 40 of the light source 12, inputs AC power as external power, converts this AC power into lighting power as a predetermined DC power, and supplies it to the light source module 34 of the light source 12, thereby lighting the light source 12.

[0026] Camera drive unit 65 is connected to camera unit 13 via camera cable 50, receives AC power as external power, converts this AC power into predetermined drive power to drive imaging unit 48 of camera unit 13, and acquires and stores images captured by camera unit 13. Camera drive unit 65 communicates with the outside world via wired or wireless communication, and transmits the acquired images to a destination such as a predetermined personal computer or the cloud.

[0027] Next, the operation of the lighting device 10 of the first embodiment will be described.

[0028] When installing lighting device 10, the shooting direction of camera unit 13 is adjusted. The angle of camera unit 13 is adjusted based on the relationship between the installation position of lighting device 10 and the direction of the subject, which is the direction in which shooting is desired. At this time, because silicone washers through which adjustment screws 62 are inserted are interposed between camera case 44 and mounting member 46 and between mounting member 46 and adjustment screws 62, the shooting direction of camera unit 13 can be adjusted even when adjustment screws 62 are tightened.

[0029] Illumination device 10 is installed in the recessed hole in the ceiling board so that the shooting direction of camera unit 13 faces in the direction of the subject from the position of the recessed hole in the ceiling board. At this time, first, the power lines drawn out from the recessed hole are connected to power supply unit 64 and camera drive unit 65, and power supply unit 64 and camera drive unit 65 are inserted through the recessed hole and installed on the ceiling board.

[0030] The lighting device 10 emits light downward by turning on the light source 12, and shoots an image of a subject in the shooting direction by driving the camera unit 13.

[0031] However, if the angle of camera unit 13 can be adjusted in the radial direction of housing 11, depending on the angle of camera unit 13, it may block the light from light source 12, affecting the light distribution. In order to prevent camera unit 13 from blocking the light from light source 12, light source 12 must be made small (small diameter), but making it small may result in a decrease in luminous flux.

[0032] In the lighting device 10, the shooting direction of the camera unit 13 can be adjusted in a direction perpendicular to the radial direction of the housing 11, so that the shooting direction of the camera unit 13 can be adjusted without having to block the light of the light source 12 with the camera unit 13 or making the light source 12 small (small diameter), that is, without affecting the light distribution or luminous flux of the light source 12.

[0033] In the first embodiment, the light source 12 is arranged in the center of the housing 11, so that when the lighting device 10 is installed, the housing 11 can be rotated in a circumferential direction to orient the shooting direction of the camera unit 13 toward the subject, with little effect on the light distribution.

[0034] Furthermore, when light source 12 is turned on, heat generated by the light-emitting elements is transferred to heat dissipation section 33 and dissipated into the air. Because imaging section 48 of camera section 13 is located below heat dissipation section 33 of light source 12 (and further below the light-emitting elements of light source section 32), heat dissipated from heat dissipation section 33 is less likely to be transferred to imaging section 48, a temperature rise in imaging section 48 due to heat generated by light source 12 is suppressed, and the quality of the video captured by imaging section 48 can be maintained.

[0035] Since the partition wall 27 is disposed between the light source 12 and the camera unit 13, the partition wall 27 can prevent the heat generated by the light source 12 from being transmitted to the camera unit 13.

[0036] Next, a second embodiment is shown in Figures 7 to 12. Note that the same components as those in the first embodiment are given the same reference numerals and their description will be omitted.

[0037] The lighting device 10 includes a cylindrical housing 11, a light source 12 arranged in the housing 11, and a camera unit 13 arranged inside the housing 11 radially aligned with the light source 12, with the light source 12 and the camera unit 13 arranged inside the same housing 11. The housing 11 of the second embodiment has a top-closed fixture structure, whereas the housing 11 of the first embodiment has a top-open fixture structure.

[0038] The housing 11 has a fixture body 70 , a decorative plate 71 disposed on the lower surface side of the fixture body 70 , and a light source housing portion 72 provided inside the fixture body 70 .

[0039] The device body 70 is made of metal and has a disk-shaped upper surface portion 73, a peripheral surface portion 74 provided around the periphery of the upper surface portion 73, and a rim portion 75 protruding radially outward from the lower end of the peripheral surface portion 74. A plurality of mounting springs 18 are attached to the outer surface of the peripheral surface portion 74.

[0040] The upper surface 73 of the fixture body 70 is formed with a circular light source opening 76 through which the heat dissipation section 33 of the light source 12 protrudes upward, and also with a long hole-shaped camera opening 77 through which the camera cable 50 is inserted. The light source opening 76 and the camera opening 77 are arranged side by side in the radial direction (diameter direction) of the housing 11. The light source opening 76 does not need to protrude from the heat dissipation section 33 of the light source 12, as long as it is located above the heat dissipation section 33 of the light source 12.

[0041] A pair of hooks 78 for attaching the decorative panel 71 are cut and formed on the inner periphery of the peripheral surface portion 74 of the fixture body 70. The pair of hooks 78 are provided at two locations on the peripheral surface portion 74 in the circumferential direction.

[0042] Decorative plate 71 is made of metal and has a disk shape. Decorative plate 71 has a circular light source window 79 formed in a position facing light source housing section 72 in housing 11 and light source 12 housed in light source housing section 72, as well as a camera window 80 in which camera section 13 is disposed. Light source window 79 and camera window 80 are arranged side by side in the radial direction of housing 11.

[0043] The middle coil portion of the torsion spring 81 is attached to the upper surface of the decorative plate 71. A pair of ends of the torsion spring 81 are hooked onto a pair of hook portions 78 of the fixture body 70, and the decorative plate 71 is pulled up and attached to the fixture body 70 by the elasticity of the both ends of the torsion spring 81 that tends to expand.

[0044] The light source accommodating section 72 has a cylindrical reflector 82 that opens in the vertical direction, a light source holder 83 attached to the top of the reflector 82, and a fixing member 84 that fixes the light source holder 83 to the underside of the upper surface section 73 of the fixture body 70. The reflector 82 is arranged coaxially with the light source opening 76 of the fixture body 70 and the light source window 79 of the decorative plate 71, with the upper surface of the reflector 82 facing the light source opening 76 of the fixture body 70 and the lower surface of the reflector 82 facing the light source window 79 of the decorative plate 71. A plurality of mounting sections 85 for detachably mounting the light sources 12 are protruded from the inner peripheral side of the light source holder 83.

[0045] The light source 12 is configured in the same manner as in the first embodiment. The light source 12 is inserted into the light source holder 83 through the reflector 82 with the insertion / removal grooves 36 aligned with the positions of the mounting portions 85 of the light source holder 83, and then rotated, whereby the mounting grooves 37 engage with the mounting portions 85, and the light source 12 is detachably attached to the light source holder 83. A portion of the heat dissipation portion 33 of the light source 12 protrudes upward through the light source opening 76 of the fixture body 70.

[0046] Furthermore, camera unit 13 includes camera body 43, a rotating ball 88 attached to the tip of camera body 43, and a holding member 45 that holds camera body 43 between itself and rotating ball 88. Camera unit 13 is attached to the underside of upper surface 73 of fixture body 70 by an attachment member 46 so that the angle can be adjusted. Image capturing unit 48 of camera unit 13 is positioned below heat dissipation unit 33 of light source 12 (and further below the light emitting element of light source unit 32).

[0047] The rotating ball 88 has a spherical portion 89 on its tip side, and a flat portion is provided on the tip surface of this spherical portion 89, forming a window hole 90 that faces the lens 49 of the camera body 43. Flat portions are provided on both sides of the rotating ball 88, into which the tip sides of the legs 53 on both sides of the holding member 45 are inserted. Screws 91 are inserted from the side of the rotating ball 88 and threaded into the legs 53 of the holding member 45, and the camera body 43 is held by the rotating ball 88 and the holding member 45.

[0048] The mounting member 46 is formed in a generally L-shape and has a fixing portion 57 that is fixed to the underside of the upper surface portion 73 of the instrument body 70 by screws, and a support portion 58 that is bent downward from the fixing portion 57 and supports the camera body 43. A screw insertion hole 60 and an arc-shaped elongated hole 61 centered on the screw insertion hole 60 are formed above the screw insertion hole 60. A screw 55 that serves as a fulcrum for insertion through the screw insertion hole 60 is threaded into the leg portion 53 of the holding member 45, and an adjustment screw 62 that passes through the elongated hole 61 is threaded into the leg portion 53 of the holding member 45.

[0049] The camera unit 13 can rotate together with an adjustment screw 62 around an angle adjustment axis 56, which is a screw 55, relative to the mounting member 46, and the angle of the shooting direction can be adjusted within a range in which the adjustment screw 62 abuts against one end or the other end of the long hole 61 and rotation is restricted.

[0050] Camera unit 13 can rotate around angle adjustment shaft 56, which faces in the radial direction (radial direction) from the center (center line) of housing 11, in a direction perpendicular to the radial direction of housing 11 (a tangential direction to the circumferential direction of housing 11), making it possible to adjust the shooting direction. Silicon washers 92, through which adjustment screws 62 are inserted, are interposed between rotating ball 88 and mounting member 46, and between mounting member 46 and adjustment screws 62, making it possible to change the angle of camera unit 13 even when adjustment screws 62 are tightened.

[0051] The rotating ball 88 of the camera unit 13 is inserted into and disposed in the camera window 80 of the decorative panel 71, protruding downward. The axis of the screw 55, which serves as the angle adjustment shaft 56 about which the camera unit 13 rotates, passes through the center of the spherical portion 89 of the rotating ball 88. Therefore, the spherical portion 89 of the rotating ball 88 is formed into an arc with the angle adjustment shaft 56 as its center with respect to the angle adjustment direction of the camera unit 13. This allows the camera unit 13 to rotate within the camera window 80 of the decorative panel 71.

[0052] The camera cable 50 of the camera unit 13 is inserted through the camera opening 77 of the device body 70. The camera opening is formed long along the direction in which the angle of the camera unit 13 can be adjusted so that the camera cable 50 can move by adjusting the angle of the camera unit 13.

[0053] The mounting member 46 and the reflector 82 are configured as a partition wall 27 disposed between the light source 12 and the camera unit 13 .

[0054] 9, a power supply unit 64 is connected to the light source 12, and a camera drive unit 65 is connected to the camera section 13. When the lighting device 10 is installed, the power supply unit 64 and the camera drive unit 65 are inserted through the recessed holes and placed on the ceiling board.

[0055] Next, the operation of the lighting device 10 of the second embodiment will be described.

[0056] When installing lighting device 10, the shooting direction of camera unit 13 is adjusted. The angle of camera unit 13 is adjusted based on the relationship between the installation position of lighting device 10 and the direction of the subject, which is the direction in which shooting is desired. At this time, because silicone washers 92, through which adjustment screws 62 are inserted, are interposed between rotating ball 88 and mounting member 46 and between mounting member 46 and adjustment screws 62, the shooting direction of camera unit 13 can be adjusted even when adjustment screws 62 are tightened.

[0057] Illumination device 10 is installed in the recessed hole in the ceiling board so that the shooting direction of camera unit 13 faces in the direction of the subject from the position of the recessed hole in the ceiling board. At this time, first, the power lines drawn out from the recessed hole are connected to power supply unit 64 and camera drive unit 65, and power supply unit 64 and camera drive unit 65 are inserted through the recessed hole and installed on the ceiling board.

[0058] The lighting device 10 emits light downward by turning on the light source 12, and shoots an image of a subject in the shooting direction by driving the camera unit 13.

[0059] In the lighting device 10 of the second embodiment, the shooting direction of the camera unit 13 can also be adjusted in a direction perpendicular to the radial direction of the housing 11, so that the shooting direction of the camera unit 13 can be adjusted without having to block the light of the light source 12 with the camera unit 13 or making the light source 12 small (small diameter), that is, without affecting the light distribution or luminous flux of the light source 12.

[0060] Furthermore, when light source 12 is turned on, heat generated by the light-emitting elements is transferred to heat dissipation section 33 and dissipated into the air. Because imaging section 48 of camera section 13 is located below heat dissipation section 33 of light source 12 (and further below the light-emitting elements of light source section 32), heat dissipated from heat dissipation section 33 is less likely to be transferred to imaging section 48, a temperature rise in imaging section 48 due to heat generated by light source 12 is suppressed, and the quality of the video captured by imaging section 48 can be maintained.

[0061] Since the partition wall 27 is disposed between the light source 12 and the camera unit 13, the partition wall 27 can prevent the heat generated by the light source 12 from being transmitted to the camera unit 13.

[0062] Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention.
