However, when the lighting device 1 is to be placed on a high ceiling such as a gymnasium or a factory, the implementer sometimes looks up to install the lighting device 1. At this time, if the terminal block 31 cannot be seen from the position of the implementer, the implementer must grasp the position of the terminal block 31 by groping. In this case, it is not easy for the operator to perform an operation of connecting the external wiring 35 to the terminal block 31 or to confirm whether or not the external wiring 35 is connected to the terminal block 31.

Therefore, in the illuminating device 1 of the embodiment, the terminal block 31 is provided at a position that is easily seen by the implementer, whereby the illuminating device 1 can be easily mounted. Hereinafter, the position at which the terminal block 31 is provided in the illuminating device 1 of the embodiment will be described in detail with reference to Figs. 2 to 4 .

First, the setting range of the terminal block 31 will be described using FIG. Fig. 2 is a view showing an installation range of the terminal block 31 of the embodiment. In FIG. 2, in order to simplify the description, the description of the main body portion 40, the heat dissipation portion 50, and the like is omitted. Further, the terminal block 31 is, for example, a rectangular parallelepiped frame, and includes a connection port 32 (see FIG. 3) for connecting the external wiring 35, which will be described later with reference to FIG. 3.

As shown in Fig. 2, in the illuminating device 1 of the embodiment, the end surface 20a of the side surface 20c which is a side surface which does not overlap the support portion 10 is viewed from the side surface side (direction perpendicular to the Z-axis of Fig. 2). A terminal block 31 is provided on the portion R. Further, the terminal block 31 may be provided on the end portion R of the rear surface 20a of the side surface 20e which is the other side surface which does not overlap the support portion 10 as viewed from the side surface side.

Here, when the terminal block 31 is provided on the end portion R of the back surface 20a, it is preferable to provide the terminal block 31 at a position as close as possible to the side surface 20c or the side surface 20e. This is because, as described above, the constructor who operates from below the illuminating device 1 can easily see the terminal block 31.

Therefore, the end portion R is preferably in a range of, for example, 30% of the length of the back surface 20a in the X-axis direction from the side surface 20c or the side surface 20e. However, the end portion R is not limited to the region where the constructor can see the terminal block 31 from the lower side of the illumination device 1.

Further, the terminal block 31 may be provided on at least a part of the terminal portion R. That is, the terminal block 31 may be provided at a position where the constructor can see at least a part of the terminal block 31 from below the illumination device 1.

Thus, by providing the terminal block 31 on the end portion R of the back surface 20a, the constructor can see the terminal block 31. Therefore, the constructor can easily connect the external wiring 35 to the terminal block 31, so that the lighting device 1 can be easily provided.

Further, by providing the terminal block 31 on the back surface 20a, the terminal block 31 or the wiring 26 (see FIG. 3) is placed at a position that is not visible from the lower side of the illumination device 1. Therefore, the lighting device 1 can be easily mounted without impairing the aesthetics of the lighting device 1.

Further, the terminal block 31 can be disposed such that a part of the terminal block 31 protrudes from the power supply box 20 as viewed from the back surface 20a side. Alternatively, a pedestal may be provided on the back surface 20a of the power supply box 20, and the terminal block 31 may be provided on the pedestal to make it easy for the constructor to see the terminal block 31. Further, for example, a slide mechanism that can slide in the X-axis direction can be provided on the back surface 20a, and the terminal block 31 is provided on the slide mechanism.

Further, as described above, in the illuminating device 1 of the embodiment, the terminal block 31 is provided on the end portion R of the side surface 20c which is the side surface which does not overlap the support portion 10 or the rear surface 20a of the side surface 20e. Therefore, when the implementer looks up to the illuminating device 1, it is possible to prevent the terminal block 31 from being blocked by the support portion 10.

Therefore, the constructor can surely see the terminal block 31. The direction of the terminal block 31 when the terminal block 31 is placed on the back surface 20a will be described later using FIG.

However, the terminal block 31 is not limited to the back surface 20a of the power supply box 20, and may be provided on the side surface. As described above, when the terminal block 31 is provided on the side surface 20c, the side surface 20e, or the side surface 20b or the end portion R of the side surface 20d, the constructor can more easily see the terminal block 31 than when it is provided on the back surface 20a. .

In this case, the direction in which the terminal block 31 is disposed is not limited, but it is preferable that the connection port 32 of the terminal block 31 faces the lower side (the Z-axis negative direction side) or the upper side (the Z-axis positive direction side). Set on.

For example, when the connection port 32 is provided in the downward direction, the connection port 32 is disposed at a position close to the constructor, and thus the connection of the external wiring 35 is facilitated. Further, when the terminal block 31 is provided in the direction in which the connection port 32 faces the upper side of the power supply box 20, the constructor can directly connect the terminal (not shown) of the external wiring 35 extending from the ceiling to the connection port in this direction. 32.

Next, an example of arrangement of the terminal block 31 will be described using FIG. 3 is a view showing an arrangement example of the terminal block 31 of the embodiment. Further, the power supply terminal block 31a and the signal terminal block 31b shown in FIG. 3 are simplified, and are not limited in size or shape.

As shown in FIG. 3, a power supply terminal block 31a and a signal terminal block 31b are provided as the terminal block 31 on the back surface 20a of the power supply box 20. Further, each of the power supply terminal block 31a and the signal terminal block 31b has a connection port 32a and a connection port 32b that connect the external wiring 35.

The power supply terminal block 31a has a power supply wiring 26a that supplies power to a control substrate provided inside the power supply box 20. Further, the signal terminal block 31b has a signal wiring 26b for supplying a signal such as a dimming signal to the control substrate.

In the following description, the power supply wiring 26a and the signal wiring 26b are collectively referred to as the wiring 26. Moreover, the wiring 26 is introduced into the inside of the power supply box 20 via the through hole 28 provided in the center part of the back surface 20a, for example.

As shown in FIG. 3, the power supply terminal block 31a and the signal terminal block 31b are attached, for example, in a posture in which the connection port 32a and the connection port 32b face the side surface 20c. In addition, when the power terminal block 31a and the signal terminal block 31b are provided on the back surface 20a on the side surface 20e side, the connection port 32a and the connection port 32b are attached to the side surface 20e.

Therefore, in addition to the positions of the power terminal block 31a and the signal terminal block 31b, the constructor can see the connection port 32a and the connection port 32b. Further, the constructor may connect the external wiring 35 to the connection port 32a and the connection port 32b without being hindered by the support portion 10.

Therefore, the constructor can easily connect the external wiring 35 to the connection port 32a and the connection port 32b. Further, as shown in FIG. 3, the terminal block 31 need not be strictly mounted in parallel with the boundary line between the back surface 20a and the side surface 20c, and may be a direction in which the connection port 32a and the connection port 32b face the side surface 20c.

Further, as shown in FIG. 3, the power terminal block 31a and the signal terminal block 31b are arranged side by side along the end portion R on the back surface 20a. Thereby, when the external wiring 35 is connected to the power supply terminal block 31a and the signal terminal block 31b, the constructor can perform work without changing the position or posture in which the constructor itself stands.

Next, a case where the posture of the illumination device 1 is tilted and mounted will be described with reference to FIG. 4 . Fig. 4 is a schematic view showing a state in which the illuminating device 1 of the embodiment is tilted. Here, a case where the illumination device 1 adopts the posture shown in FIG. 4 in a state where the support portion 10 is fixed to the ceiling will be described.

The main body portion 40 is preferably supported by the support portion 10 so as to be in a horizontal posture or a posture inclined downward toward the end portion R side where the terminal block 31 is provided. In this manner, the main body portion 40, that is, the power supply box 20 is tilted so that the end portion R side of the terminal block 31 is lowered, whereby the operator can more easily see the terminal block 31. Further, at this time, the terminal block 31 is brought close to the constructor only by tilting the power supply box 20. Therefore, the constructor can connect the external wiring 35 at a closer position.

As described above, when the body portion 40 is tilted, the terminal block 31 of the power supply box 20 is preferably located on the lower end portion R side. That is, when the illuminating device 1 is mounted on a ceiling or the like, the illuminating device 1 may be mounted in the direction in which the terminal block 31 is located on the lower end portion R side.

Further, the swing range of the main body portion 40 with respect to the support portion 10 may be changed to a direction that is inclined downward toward the end portion R side on which the terminal block 31 is provided.

In addition, when the illuminating device 1 is placed on the inclined ceiling, the rear surface 20a of the power supply box 20 may be in a horizontal posture or inclined downward toward the end portion R side of the terminal block 31.

In the above-described embodiment, the lighting device 1 is provided with one power supply case 20 and one main unit 40, but the present invention is not limited thereto. In other words, the illumination device 1 may include one power supply box 20 and a plurality of main body portions 40, and may include a plurality of power supply boxes 20 and one main body portion 40. Further, the plurality of light emitting portions 60 may be arranged side by side on the main body portion 40.
