The holder 20 has an axial portion 201 having an outer diameter smaller than a portion between both ends of the holder 20 at each of both axial ends. The shaft body 7 is inserted into each hole 204 of the pair of shaft portions 201 of the holder 20.

  The hinge device 5 can rotate the light source unit 3 between the first position (hereinafter also referred to as “reference position”) and the second position (hereinafter also referred to as “deployed position”) around the first axis 50. The light source unit 3 is connected to the base 2 in the following manner. The reference position is a position at which the other light source unit 3 and the tip end are closest to each other in each of the plurality of light source units 3 (the position of the light source unit 3 indicated by a solid line in FIG. 11). The development position is a position (a position of the light source unit 3 indicated by a two-dot chain line in FIG. 11) rotated by the maximum rotation angle from the reference position in each of the plurality of light source units 3.

  The hinge device 5 includes a bearing portion 51, a ring portion 52, a connection portion 53, a hinge portion 54, and an arm 55.

The click projection 572 can be moved into and out of each of the plurality of recesses 561 of the click plate 56. The return spring is a coil spring. The return spring applies a force in the direction of causing the click projection 572 to protrude from the shaft portion 201 to the flange portion of the click member 57. Thereby, the click projection 572 is movable between a position where it protrudes from the shaft portion 201 and a position where it does not protrude. In the luminaire 1, when the user rotates the light source unit 3 around the first axis 50, the position of the light source unit 3 can be easily maintained at a desired rotational position. Moreover, in the lighting fixture 1, when the user rotates the light source unit 3, the user can obtain a click feeling.

  The luminaire 1 includes the plurality of hinge devices 5 as described above, and is configured such that the rotational directions when the plurality of light source units 3 rotate from the reference position to the deployed position are different. More specifically, in the lighting fixture 1, the two hinge devices 5 are arranged such that the click plates 56 do not overlap in the direction of the first axis 50. Hereinafter, for convenience of explanation, one of the two light source units 3 may be referred to as a light source unit 3A, and the other light source unit 3 may be referred to as a light source unit 3B. In the example of FIG. 11, the light source unit 3A is at the reference position of the light source unit 3A, and the light source unit 3B is at the reference position of the light source unit 3B. In FIG. 11, the light source unit 3A rotated to the unfolded position of the light source unit 3A is indicated by a two-dot chain line, and the light source unit 3B rotated to the unfolded position of the light source unit 3B is indicated by a two-dot chain line. The rotation angle from the reference position of the light source unit 3 around the first axis 50 to the deployed position by the hinge device 5 is approximately 90 degrees.

  The rotation mechanism 6 couples the light source unit 3 to the hinge device 5 so that the light source unit 3 can rotate about a second axis 60 intersecting the first axis 50.

  The rotation mechanism 6 has a shaft 61 and a bearing 62. The shaft 61 is connected to the light source unit 3 at one end in the longitudinal direction of the light source unit 3. The shaft portion 61 protrudes from the surface of the light source unit 3 facing the arm 55 of the hinge device 5. The shaft 61 is cylindrical. The bearing portion 62 is provided on the arm 55 and rotatably holds the shaft portion 61. In the luminaire 1, the second shaft 60 is defined by the bearing portion 62. In the lighting device 1, a pair of power supply lead wires and the like are passed through the shaft portion 61. The pair of feed lead wires are a pair of lead wires for electrically connecting the light source unit 3 and the lighting circuit.

  In the rotation mechanism 6, the shaft portion 61 is connected to the arm 55 so as to be rotatable around a second axis 60 in a prescribed angle range (for example, 330 degrees) smaller than 360 degrees. The rotation angle of the light source unit 3 around the second axis 60 by the rotation mechanism 6 is approximately 330 degrees.

  The plurality of light source units 3 are gathered when the plurality of light source units 3 are at the reference position, and the plurality of rotation mechanisms 6 are in the reference state in which the light emission surfaces 3222 of the plurality of light source units 3 face outward. Thus, the range of rotation about the second axis 60 of each of the plurality of light source units 3 is defined. The plurality of light source units 3 are individually rotatable around the first axis 50 and around the second axis 60. However, when each of the plurality of light source units 3 is at the reference position, each of the plurality of light source units 3 can only rotate around the first axis 50 and rotation around the second axis 60 is prohibited. . When at least one light source unit 3 of the plurality of light source units 3 is in a position rotated about the first axis 50 from the reference position, each of the plurality of light source units 3 can rotate about the second axis 60 Become. FIG. 12 shows an example in which each of the plurality of light source units 3 is rotated by 90 degrees around the second axis 60.

  In the lighting device 1, the light emitting surfaces 3222 of the two light source units 3 can be made to face each other by the connecting device 4.

  In the lighting device 1, the above-described circuit unit is configured to be able to receive power from the battery pack 8 attached to the attachment portion 9 and to light the light sources 30 of the plurality of light source units 3.

In addition, the circuit unit has a power supply circuit that DC-DC converts a DC voltage supplied from the battery pack 8 into a predetermined power supply voltage and supplies the DC voltage to the lighting circuit. The power supply circuit is, for example, a boost chopper circuit. The lighting circuit is, for example, a constant current circuit including a switching element, a resistor, and a control IC (Integrated Circuit) as a component. Therefore, the lighting circuit can supply a constant current to the LED module 31. The constant current circuit is, for example, a step-down chopper circuit. The switching element is, for example, an enhancement type n-channel MOSFET. The control IC controls the on / off of the switching element. The control IC is configured to adjust the magnitude of the current value of the constant current supplied from the constant current circuit to the LED module 31 by controlling the on / off of the switching element. The current value at the time of rated lighting of the LED module 31 is, for example, 280 mA. In addition, the current value when the light modulation lighting is performed so that the LED module 31 has a light output of 10% of the light output at the time of rated lighting is, for example, 28 mA.

  The circuit unit also includes a control power supply circuit that DC-DC converts the DC voltage supplied from the battery pack 8 into a predetermined control voltage (for example, 5 V) and supplies the control voltage to the control unit. The control power supply circuit includes, for example, a three-terminal regulator and a capacitor. The control unit includes a microcomputer (Microcontroller). The microcomputer is configured as a one-chip device including a processor that operates according to a program, a memory for storing a program that operates the processor, and a working memory. The control unit can be realized by causing a microcomputer to execute a program.

  In the lighting device 1, when the operation switch is operated, the control unit of the circuit unit acquires the operation signal. Here, “the control unit acquires the operation signal” may be that the control unit detects that the operation switch has been operated. The control unit acquires an operation signal each time the operation switch is operated. The control unit is configured to change the plurality of light source units 3 in the order of the full lighting state, the first light control lighting state, the second light control lighting state, and the light off state each time the operation signal is acquired. Thereby, the lighting fixture 1 can realize various lighting scenes. The light output in the first dimming control state of the light source unit 3 is, for example, 50% of the light output in the full lighting state, and the light output in the second dimming control state is, for example, all lighting It is 10% of the light output in the state, and the light output in the off state is 0% of the light output in the full lighting state. The control unit has an output unit that outputs a light adjustment signal for instructing the lighting circuit to have the light output of the light source unit 3.

  The lighting fixture 1 includes a fixture body 11 and a base 12. The instrument body 11 includes a base 2, a coupling device 4, a mounting portion 9, and two light source units 3.

The base 12 is formed of, for example, an ABS resin or the like.

  The luminaire 1 further comprises a hanging hook 18 rotatably held by the instrument body 11 and the base 12. Here, the base 12 includes a pair of side walls 120 along the longitudinal direction of the base 2. Further, the pair of side walls 120 has a pair of grooves 17 in which both sides in the direction along the instrument body 11 side and the short direction of the base 2 are open.

  The suspension hook 18 has a pair of shaft portions 181. More specifically, as shown in FIG. 9, the suspension hooks 18 have a pair of J-shaped hook main body portions 180 and a pair of shafts projecting in the direction toward each other from the proximal ends of the pair of hook main body portions 180.
