Next, the operation of the present embodiment will be described.
FIG. 12 shows a perspective view of the lighting device 1, and in particular shows an initial state of the angle adjustment device 2. In the initial state of the angle adjustment device 2, the horizontal rotational position of the horizontal rotary frame 5 (horizontal direction rotary portion) is 0 °, and in the vertical direction of the vertical rotary frame 9 (vertical direction rotary portion). Rotation position is 0 °. Further, in the initial state of the angle adjustment device 2, the irradiation direction of the illumination device 1 is the directly downward direction (vertical direction). Here, what is shown in FIG. 13 is a view when the lighting device 1 in the initial state of the angle adjustment device 2 is viewed from a different line of sight from FIG. 12.

  The operator can remotely control the irradiation direction of the illumination device 1 (hereinafter simply referred to as “irradiation direction”) by operating the remote controller (control unit). For example, in the case where the irradiation direction is inclined clockwise from 0 ° in the initial state from the line of sight in the A direction in FIG. 12, the second motor 34 rotates the rotational shaft 34A to the number of pulse inputs by the operation of the remote controller by the operator. It rotates in the specified direction by the corresponding rotation angle (angular displacement). Then, the rotation of the rotation shaft 34A of the second motor 34 is transmitted to the second gear mechanism 35 via the second pinion 41, and the large gear 40 of the second stepped spur gear 38 meshed with the second pinion 41 (second Gear), the small gear 39 (first gear) of the second stepped spur gear 38, and the external gear 42 meshed with the small gear 39, the speed is reduced and transmitted to the vertical rotation frame 9.

  Thereby, as shown in FIG. 14, the vertical rotation frame 9 can be rotated in the vertical direction, and as a result, the irradiation direction can be inclined at a designated angle. Here, what is shown in FIG. 15 is a perspective view of the lighting device 1 in a state corresponding to FIG. 14 and is a perspective view of the lighting device 1 when viewed from a different line of sight from FIG.

  On the other hand, for example, in the state shown in FIG. 15, the irradiation direction is rotated in the horizontal direction, in other words, the irradiation direction (irradiation axis) is the center line is the axis of the illumination device 1 (the center line of the embedding hole) When moving (rotating) along the side of the coincident cone, the first motor 24 is designated by the rotation angle (angular displacement amount) corresponding to the number of pulse inputs of the first motor 24 by the operation of the remote controller by the operator Rotate in the direction. Then, the rotation of the rotation shaft 24A of the first motor 24 is transmitted to the first gear mechanism 25 via the first pinion 31, and the small gear 29 of the first stepped spur gear 28 meshed with the first pinion 31 (first The speed is transmitted to the horizontal rotation frame 5 via the gear), the large gear 30 (second gear) of the first stepped spur gear 28, and the internal gear 32 meshed with the large gear 30.

  Thereby, the horizontal rotation frame 5 rotates in the horizontal direction, and as a result, the irradiation direction (the irradiation axis) can be rotated in the horizontal direction while maintaining the inclination angle with respect to the vertical line. In addition, although the rotation operation in the horizontal direction of the horizontal rotation frame 5 by the first drive unit 23 and the rotation operation in the vertical direction of the vertical rotation frame 9 by the second drive unit 33 have been described separately, the control unit The first drive unit 23 and the second drive unit 33 can be simultaneously controlled by the operation of the remote controller by the operator. That is, the angle adjustment device 2 can simultaneously perform the rotation operation of the horizontal rotation frame 5 in the horizontal direction and the rotation operation of the vertical rotation frame 9 in the vertical direction.

The following effects are achieved in this embodiment.
According to the present embodiment, on the horizontal rotation frame 5 (horizontal direction rotation portion), the first drive portion for rotating the horizontal rotation frame 5 in the horizontal direction and the vertical rotation frame 9 (vertical direction rotation portion) are vertically The angle adjustment device 2 is configured by disposing a second drive unit for rotationally driving in the direction.
By applying such an angle adjustment device 2, the lighting device 1 can be miniaturized, in particular, the overall length can be shortened, for example, suitable for a ceiling-mounted universal downlight with limited depth. The lighting device 1 can be provided. Further, by forming the inner teeth 32 constituting the first gear mechanism 25 on the inner periphery of the fixed frame 3, the horizontal direction of the angle adjusting device 2 is compared with the case where outer teeth are formed on the outer periphery of the fixed frame 3. Thus, it is possible to reduce the outer diameter of the fixed frame 3 and hence the fixed frame 3, and to provide the lighting device 1 capable of coping with smaller embedded holes.

Further, in the present embodiment, a stepped spur gear having the same shape is used for the first stepped spur gear 28 incorporated in the first gear mechanism 25 and the second stepped spur gear 38 incorporated in the second gear mechanism 35. By meshing the 28 small gears 29 (first gear) with the first pinion 31 fixed to the rotation shaft 24A of the first motor 24, and with the large gear 40 (second gear) of the second stepped spur gear 38 The angle adjustment device 2 was configured.
By using the stepped spur gears 28 and 38 of the same shape as described above for the acceleration side and the deceleration side, it is possible to use a stepping motor of the same shape (same model) for the first motor 24 and the second motor 34 Thus, the first drive unit 23 and the second drive unit 33, as well as the angle adjustment device 2 can be configured simply. In addition, productivity can be improved by achieving common parts that configure the apparatus, and at the same time, manufacturing costs can be reduced.
In addition, since most of the first drive unit 23 and the second drive unit 33 are configured by a common component, the first drive unit 23 and the second drive unit 33 can be used as the center line of the lighting device 1 (this embodiment In this case, by arranging them symmetrically with respect to the rotation axis of the horizontal rotation frame 5) or the optical axis of the illumination device 1, the weight balance of the entire device can be easily equalized, and smooth angle adjustment becomes possible.
Similarly, to arrange the first drive unit 23 and the second drive unit 33 symmetrically with respect to a straight line coinciding with the rotation axis of the horizontal rotation frame 5, the vertical rotation frame 9 corresponds to the first drive unit 23 or the This arrangement position allows the size of each component to be minimized while rotating in the vertical direction without interference with the driving unit 33.
In addition, the horizontal rotation angle (angular displacement amount) of the horizontal rotation frame 5 when the first motor 24 receives one pulse, and the vertical rotation frame 9 when the second motor 341 pulse is input. Since the shapes of the stepped spur gears 28 and 38 are selected so that the rotation angle (angular displacement amount) in the vertical direction matches or becomes equal, control by the control unit can be simplified and reliability And the manufacturing cost can be reduced.
Furthermore, the angle adjustment device 2 has a function of electrically detecting the rotation angles of the horizontal rotation frame 5 and the vertical rotation frame 9 and a function of mechanically limiting the rotation of the horizontal rotation frame 5 and the vertical rotation frame 9 I have it together. As a result, damage to the device can be reliably prevented, which in turn can improve the reliability of the device.

Adaptation to the type to be performed is also possible.
The motors 24 and 34 are not limited to the stepping motor, and a DC motor, a DC brushless motor, an AC motor or the like can be applied. Also in this case, the rotation angle (angle displacement amount) of the horizontal rotation frame 5 in the horizontal direction and the rotation angle (angle displacement amount) of the vertical rotation frame 9 in the vertical direction match or become equal to each other.
