In addition, the terminal block cover 30 has a wiring hole on the side surface, and the external wiring 35 is connected to the terminal block 31 from the outside through the wiring hole. For example, after the lighting device 1 is installed, the terminal block cover 30 is installed by a builder. Furthermore, the terminal block cover 30 may be omitted.

The terminal block 31 includes, for example, a power terminal block 31a connected to the power line 35a of the external wiring 35 drawn in from the back of the ceiling, and a signal terminal block 31b connected to the signal line 35b. In the following description, the power terminal block 31a and the signal terminal block 31b may be collectively referred to as the terminal block 31. In addition, in the following description, a case where there are two terminal bases 31 will be described, but there may be one terminal base 31 or three or more terminal bases.

Here, in the lighting device 1 of the embodiment, when the lighting device 1 is installed In this case, the terminal block 31 is installed in a position where the operator can easily see it. The detailed description of this point will be described later using the figures of FIG. 2 and later.

However, when the lighting device 1 is to be installed on a high ceiling such as a gymnasium or a factory, the constructor 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 builder, the builder must grasp the position of the terminal block 31 by fumbling. In this case, it is not easy for the builder to perform the work of connecting the external wiring 35 to the terminal block 31 or the work of confirming whether the external wiring 35 is connected to the terminal block 31 or not.

Therefore, in the lighting device 1 of the embodiment, the terminal block 31 is installed in a position that is easy for a worker to see, so that the lighting device 1 can be easily installed. Hereinafter, the position where the terminal block 31 is installed in the lighting device 1 of the embodiment will be described in detail using FIGS. 2 to 4.

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

As shown in FIG. 2, in the lighting device 1 of the embodiment, viewed from the side surface (direction perpendicular to the Z axis in FIG. 2), the end of the back surface 20a close to the side surface 20c that is the side surface on which the support portion 10 does not overlap A terminal block 31 is provided on the part R. Furthermore, when viewed from the side surface, a terminal block 31 may be provided on the end R of the back surface 20a close to the side surface 20e that is the other side surface on which the support portion 10 does not overlap.

Here, when the terminal base 31 is installed on the end R of the back surface 20a, it is preferable to install the terminal base 31 as close to the side surface 20c or the side surface 20e as possible. The reason is that as described above, the terminal block 31 can be easily seen by a builder who works from below the lighting device 1.

Therefore, the end R is preferably, for example, a range that is less than 30% of the length in the X-axis direction of the back surface 20a from the side surface 20c or the side surface 20e. However, it is not limited to this, and the end R may be an area where the operator can see the terminal block 31 from below the lighting device 1.

In addition, the terminal block 31 only needs to be provided on the end R at least partially. That is, the terminal block 31 may be installed in a position where at least a part of the terminal block 31 can be seen from below the lighting device 1 by the constructor.

In this way, by installing the terminal block 31 on the end R of the back surface 20a, the operator can see the terminal block 31. Therefore, the builder can easily connect the external wiring 35 to the terminal block 31, and therefore can easily install the lighting device 1.

In addition, by providing the terminal block 31 on the back surface 20a, the terminal block 31 or the wiring 26 (refer to FIG. 3) is arranged in a position invisible from below the lighting device 1. Therefore, the lighting device 1 can be easily installed without impairing the aesthetics of the lighting device 1.

In addition, when viewed from the back side 20a side, the terminal block 31 can be arranged such that a part of the terminal block 31 protrudes from the power supply box 20. Alternatively, a base may be provided on the back side 20a of the power supply box 20, and a terminal base 31 may be provided on the base, so that the operator can easily see the terminal base 31. In addition, for example, a sliding mechanism capable of sliding in the X-axis direction may be provided on the back surface 20a, and the terminal block 31 may be provided on the sliding mechanism.

In addition, as described above, in the lighting device 1 of the embodiment, the terminal block 31 is provided on the end portion R of the back surface 20a close to the side surface 20c or the side surface 20e that does not overlap with the support portion 10. Therefore, when a worker looks up and works on the lighting device 1, it is possible to prevent the terminal block 31 from being blocked by the support part 10.

Therefore, the builder can see the terminal block 31 reliably. In addition, the direction of the terminal block 31 when the terminal block 31 is installed on the back surface 20a is mentioned later using FIG. 3. 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. In this way, when the terminal block 31 is installed on the side surface 20c, the side surface 20e, or the side surface 20b or the end portion R of the side surface 20d, it is easier for the operator to see the terminal block 31 than when it is installed on the back surface 20a. .

Furthermore, in this case, the installation direction of the terminal block 31 is not limited, but it is preferable that the connection port 32 of the terminal block 31 faces the downward side (the Z-axis negative direction side) or the upper side (the Z-axis positive direction side). Set up.

For example, if the connection port 32 is provided in the downward direction, the connection port 32 is arranged at a position close to the worker, and therefore the connection of the external wiring 35 becomes easy. In addition, if the terminal block 31 is provided in the direction of the connection port 32 toward the upper side of the power supply box 20, the builder can directly connect the terminal (not shown) of the external wiring 35 extending from the ceiling to the connection port in this direction 32 on.

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

As shown in FIG. 3, a power terminal block 31a and a signal terminal block 31b are provided as a terminal block 31 on the back surface 20a of the power supply box 20. In addition, the power terminal block 31a and the signal terminal block 31b respectively have a connection port 32a and a connection port 32b to which the external wiring 35 is connected.

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

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

As shown in FIG. 3, the power terminal block 31a and the signal terminal block 31b are attached with the posture in which the connection port 32a and the connection port 32b faced the side surface 20c, for example. Furthermore, when the power terminal block 31a and the signal terminal block 31b are installed on the back surface 20a on the side surface 20e side, they are attached with the connection port 32a and the connection port 32b facing the side surface 20e.

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

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

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

Next, a case where the illuminating device 1 is installed while tilting the posture will be described using FIG. 4. Fig. 4 is a schematic diagram when the illuminating device 1 of the embodiment is installed at an angle. Here, a case where the lighting 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 part 40 is preferably supported by the support part 10 in a horizontal posture or a posture inclined downward toward the end R side where the terminal block 31 is provided. In this way, the main body 40, that is, the power supply box 20, is tilted so that the end R side where the terminal block 31 is provided is lowered, so that the operator can more easily see the terminal block 31. Furthermore, at this time, the terminal block 31 is brought close to the builder only by tilting the power supply box 20. Therefore, the builder can connect the external wiring 35 at a closer position.

In this way, when the main body 40 is inclined, the terminal block 31 of the power supply box 20 is preferably located on the lower end R side. That is, when mounting the lighting device 1 on a ceiling or the like, it is only necessary to install the lighting device 1 in the direction in which the terminal block 31 is located on the lower end R side.

Furthermore, the swing range of the main body portion 40 with respect to the support portion 10 may be set to only become a direction inclined downward toward the end R side where the terminal block 31 is provided.

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

In addition, in the said embodiment, although the case where the lighting device 1 is equipped with the power supply box 20 and the main body part 40, it is not limited to this. That is, the lighting device 1 may include one power supply box 20 and a plurality of main body portions 40, or may include a plurality of power supply boxes 20 and one main body portion 40. In addition, a plurality of light emitting parts 60 may be arranged side by side on the main body part 40.

Although the embodiment of the present invention has been described, the embodiment is proposed as an example and does not intend to limit the scope of the invention. This embodiment can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. In the same way as they are included in the scope and spirit of the invention, these embodiments and modifications thereof are included in the invention described in the scope of the patent application and the equivalent scope thereof.
