Further, the second concave portion 25 of the frame 20 is composed of a second horizontal flat surface portion 21b, a third horizontal flat surface portion 21c, and a second connecting portion 21e. That is, the first concave portion 24 and the second concave portion 25 have a common second horizontal plane portion 21b, and the first concave portion 24 and the second concave portion 25 are continuously formed. Therefore, the first recess 24 and the second recess 25 have a structure that is bent left and right so that the U-shape and the inverted U-shape are continuous in a substantially S-shape in the XZ cross section. There is. Specifically, in the fixed portion between the frame 20 and the panel 30, the first recess 24 and the second recess 25 of the frame 20 have a labyrinth structure having five bent portions.

Then, the convex portion 33 of the panel 30 is inserted into the first concave portion 24. Since the first recess 24 is recessed inward so as to have an opening on the outside, the convex portion 33 of the panel 30 is configured to project from the outside to the inside in the first recess 24. .. Specifically, since the second concave portion 25 exists on the first concave portion 24, the panel 30 has the frame 20 so as to sandwich the second concave portion 25 from the side between the side plate portion 32 and the convex portion 33 of the panel 30. It is fixed to.

At this time, in the fixed portion between the frame 20 and the panel 30, the side surface of the frame 20 and the side surface of the panel 30 are flush with each other. Specifically, the outer surface of the first side plate portion 21 of the frame 20 and the outer surface of the side plate portion 32 of the panel 30 are flush with each other.

Therefore, the second recess 25 located above the first recess 24 is formed so that the outer surface of the second recess 25 recedes inward from the outer surface of the first side plate portion 21. .. That is, the outer surface of the second connecting portion 21e is located inside the outer surface of the first side plate portion 21. The second recess 25 and the side plate portion 32 of the panel 30 are close to each other. Specifically, the second connecting portion 21e and the side plate portion 32 of the panel 30 are in close proximity to each other.

Further, the surface where the first concave portion 24 of the frame 20 and the convex portion 33 of the panel 30 are close to each other is at least two or more. Specifically, the surfaces in which the first concave portion 24 and the convex portion 33 are close to each other are the upper surface of the first horizontal plane portion 21a and the lower surface of the second horizontal plane portion 21b. Further, in the present embodiment, the outer side surface (bottom surface of the first concave portion 24) of the first connecting portion 21d exists as a surface where the first concave portion 24 and the convex portion 33 are close to each other.

Next, one of the effects of the lighting fixture 1 according to the present embodiment will be described with reference to FIG. 7. FIG. 7 is a diagram for explaining the waterproof effect of the lighting fixture 1 according to the embodiment.

As described above, in the lighting fixture 1 according to the present embodiment, the panel 30 has a convex portion 33 protruding inward on the light source unit 10 side of the panel 30, and the frame 20 has this convex portion 33. It has a first concave portion 24 into which the convex portion 33 is inserted.

With this configuration, when the luminaire 1 is installed so that the illuminating light is irradiated on the upper side (vertically upper side), even if the luminaire 1 is splashed with water due to rainwater or the like, the water on the luminaire 1 is applied. Is drained along the outer surface of the luminaire 1 by the path indicated by the arrow in FIG. 7 without invading the inside of the luminaire 1.

For example, as shown in FIG. 7, when water splashes on the upper surface of the panel 30, the water moves laterally along the outer surface of the main body portion 31 of the panel 30 and with the outer surface of the side plate portion 32 of the panel 30. , The outer surface of each of the first side plate portion 21, the second side plate portion 22, and the third side plate portion 23 of the frame 20 flows in order to the lower part of the body 50.

At this time, since the third side plate portion 23 of the frame 20 covers the side plate portion 51 of the body 50 from the outside, water flowing downward along the surface of the third side plate portion 23 of the frame 20 reaches the frame 20 and the body 50. It is possible to suppress the infiltration into the inside through the gap of.

As described above, according to the luminaire 1 according to the present embodiment, even if the luminaire is installed so that the illuminating light is irradiated on the upper side, the infiltration of water from above can be effectively suppressed. Can be done. Therefore, it is possible to realize the lighting fixture 1 with waterproof measures without using the waterproof packing.

Further, in the present embodiment, since the outer surface of the main body portion 31 of the panel 30 is inclined, it is possible to suppress the accumulation of water on the outer surface of the panel 30. As a result, it is possible to prevent the light distribution characteristics of the illumination light emitted from the luminaire 1 from being deteriorated or the luminous flux from being lowered by the water existing on the outer surface of the panel 30.

Further, in the lighting fixture 1 according to the present embodiment, as shown in FIG. 3, the first concave portion 24 of the frame 20 and the convex portion 33 of the panel 30 are located between the lens 40 and the light source unit 10. There is. That is, the fixed portion between the frame 20 and the panel 30 is located between the lens 40 and the light source unit 10.

With this configuration, the light source module 11 is located below the mounting surface of the panel 30, so that if the luminaire 1 is installed upside down in an environment exposed to water (for example, the illumination light is on the lower side). Even if water infiltrates the inside of the luminaire 1 and collects on the surface of the lens 40 (when the light is installed so as to be irradiated to the lens 40), the water collected in the lens 40 comes from the fixed portion between the frame 20 and the panel 30. Go through. As a result, it is possible to prevent water from infiltrating into the charging portion (electrical parts, etc.) of the lighting fixture 1. That is, it is possible to suppress an unsafe event when the lighting fixture 1 is reversely mounted.

Moreover, since the fixing portion between the frame 20 and the panel 30 is located between the lens 40 and the light source unit 10, the frame 20 and the panel 30 can be fixed by using the lower portion of the lens 40. , It is possible to reduce the height of the lighting fixture 1.

Further, in the lighting fixture 1 according to the present embodiment, as described above, there are at least two or more surfaces in which the first concave portion 24 of the frame 20 and the convex portion 33 of the panel 30 are close to each other.

With this configuration, the fixed portion between the frame 20 and the panel 30 can be made into a labyrinth structure, so that it is possible to further suppress the infiltration of water from the fixed portion between the frame 20 and the panel 30.

Moreover, by forming the fixed portion between the frame 20 and the panel 30 into a labyrinth structure, it becomes difficult for the light from the light source module 11 to reach the inlet portion of the gap between the panel 30 and the frame 20. As a result, it is possible to prevent insects from invading the inside of the lighting fixture 1 by attracting insects by the light leaking from the gap between the panel 30 and the frame 20. Further, since the fixed portion between the frame 20 and the panel 30 has a labyrinth structure, the gap between the frame 20 and the panel 30 is inserted like a maze. As a result, even if insects enter through the gap between the frame 20 and the panel 30, it is possible to prevent the insects from invading the inside of the lighting fixture 1 through the gap between the frame 20 and the panel 30.

As a result, even if water enters the bottom portion 52 of the body 50, it can be drained from the drain hole 55. For example, the drain hole 55 is provided at the lower end of the end fitting 53 in the width direction.

Further, in the lighting fixture 1 of the present embodiment, as shown in FIG. 3, the power supply unit 61 and the light source unit 10 are arranged with a gap, and the power supply unit 61 and / or the light source unit are arranged in this gap. An internal conductive wire connected to 10 is arranged. Specifically, the internal conductive wire connected to the power supply unit 61 and / or the light source unit 10 is arranged in the space inside the power supply mounting bracket 62 arranged between the power supply unit 61 and the light source unit 10. ..

With this configuration, even if water infiltrates from the fixed portion between the frame 20 and the body 50, the gap between the power supply unit 61 and the light source unit 10 does not serve as an inundation path. It is possible to ensure the electrical safety of the connector. The internal conductive wire will be described later.

Moreover, by arranging the power supply unit 61 and the light source unit 10 with a gap, the power supply unit 61 and the light source unit 10 (light source module 11) as a heat source can be separated from each other, and the power supply unit 61 can be separated from the light source unit 10. You can keep it away. As a result, it is possible to prevent the power supply unit 61 from failing due to the heat of the light source unit 10.

As described above, since the luminaire 1 according to the present embodiment is installed so that the illuminating light is irradiated on the upper side, there is basically no danger of falling downward, but the luminaire 1 is oriented in the direction. Since it is assumed that the lighting fixture 1 will be used without restrictions, the lighting fixture 1 in the present embodiment is provided with fall prevention measures.

Specifically, as shown in FIGS. 13 and 14, the frame 20 and the body 50 are connected by a wire 100. Specifically, one end of the wire 100 is connected to the power supply mounting bracket 62 attached to the frame 20, and the other end of the wire 100 is connected to the wire fixing member 101 attached to the body 50. .. That is, the frame 20 and the body 50 are indirectly connected by the wire 100. The wire 100 is a metal wire or the like having high rigidity. In this embodiment, two wires 100 are used.

In this way, by connecting the frame 20 and the body 50 with the wire 100, even when the luminaire 1 is installed upside down (for example, when the luminaire 1 is installed so as to irradiate the lower side). , The frame 20 can be prevented from falling from the body 50.

Further, as shown in FIG. 13, the luminaire 1 includes an internal conductive wire 92 whose one end is connected to the power supply unit 61 and / or the light source unit 10. The internal conductive wire 92 has an internal power supply line 92a having one end connected to the power supply unit 61 and the other end connected to the input power supply power line 91a, and one end connected to the light source unit 10 and the other end being for input control.

The internal power supply power line 92a and the internal control signal line 92b are composed of, for example, one or more lead wires in which a lead wire serving as a core wire is insulated and coated.

A connector 92a1 is provided at the end of the internal power supply power line 92a, and a connector 91a1 is provided at the end of the input power supply power line 91a. By connecting the connector 92a1 and the connector 91a1, the internal power supply power line 92a and the input power supply power line 91a are connected.

Further, a connector 92b1 is provided at the end of the internal control signal line 92b, and a connector 91b1 is provided at the end of the input control signal line 91b. By connecting the connector 92b1 and the connector 91b1, the internal control signal line 92b and the input control signal line 91b are connected.

Specifically, the length of each of the two wires 100 is the internal power supply power line 92a or the internal control signal line from the portion held by the tension stop member 81 in the input power supply power line 91a or the input control signal line 91b. It is shorter than the total length of the length to the connecting portion with the 92b and the total length of the internal power supply line 92a or the internal control signal line 92b.

With this configuration, even if tension is applied to the wire 100 when the frame 20 is attached to the body 50, tension is not applied to the input conductive wire 91 and the internal conductive wire 92, so that the input conductive wire 91 and the internal conductive wire 91 are not tensioned. It is possible to prevent the 92 from being disconnected. As a result, it is possible to reduce the risk that the input conductive wire 91 and the internal conductive wire 92 are disconnected and the user receives an electric shock.

It is preferable that the length of the wire 100 is further shorter than the length of the internal conductive wire 92. That is, the length of the wire 100 may be shorter than the length of the internal power supply power line 92a or the internal control signal line 92b.

Next, the wiring layout of the lighting fixture 1 according to the embodiment will be described with reference to FIG. FIG. 15 is a schematic diagram showing a wiring layout of the lighting fixture 1 according to the embodiment.

As shown in FIG. 15, the input conductive wire 91 is connected to the internal conductive wire 92. Specifically, the input power supply power line 91a, which is one of the input conductive lines 91, and the internal power supply power line 92a, which is one of the internal conductive lines 92, are connected to each other, and the other one of the input conductive lines 91. The input control signal line 91b is connected to the internal control signal line 92b, which is one of the other internal conductive lines 92.

First, the flow of electric power will be explained. When commercial AC power is input as power from the input power line 91a, the power is branched by the branch connector 94 via the internal power line 92a, and each is one of the internal conductive lines 92. It is branched into a certain first branch internal power supply line 92c and a second branch internal power supply line 92d.

Since the end of the first branch internal power supply line 92c is connected to the power supply unit 61, the power supply supplied to the first branch internal power supply line 92c is input to the power supply unit 61.

The power supply power input to the power supply unit 61 via the first branch internal power supply power line 92c is converted into DC power by the power supply unit 61, and the DC power is inside the light source supply which is one of the internal conductive lines 92. It is supplied to the light source module 11 via the power supply line 92e. As a result, the light source module 11 emits light.

The DC power supplied to the light source module 11 is supplied to the light source module 11 adjacent to the light source module 11 via the feed internal power supply power line 92f, which is one of the internal conductive lines 92. As a result, the adjacent light source module 11 also emits light.

Further, when connecting a plurality of lighting fixtures 1, two adjacent lighting fixtures 1 are connected by a connecting conductive wire 93. The connecting conductive wire 93 includes a connecting power supply power line 93a, which is a feed wiring for supplying DC power from one of two adjacent lighting fixtures 1 to the other, and a control signal line from one of the two adjacent lighting fixtures 1 to the other. Includes a connection control signal line 93b, which is a feed wiring for transmitting the above. The connection power line 93a supplies power from the lighting fixture 1 to the other lighting fixture 1. The connection control signal line 93b transmits a control signal from the luminaire 1 to another luminaire 1. The connection power supply line 93a and the connection control signal line 93b are composed of, for example, one or more lead wires in which a lead wire serving as a core wire is insulated and coated.

A connector 93a1 is provided at the end of the connecting power supply power line 93a, and a connector 92d1 is provided at the end of the second branch internal power supply line 92d. By connecting the connector 93a1 and the connector 92d1, the connection power line 93a and the second branch internal power line 92d are connected.

Therefore, the DC power branched by the branch connector 94 via the internal power supply power line 92a and supplied to the second branch internal power supply power line 92d is connected to the luminaire 1 via the connection power supply power line 93a. It is supplied to the adjacent lighting fixture 1.

Next, the flow of control signals will be described. When a control signal is input from the input control signal line 91b, the control signal is transmitted to the light source module 11 via the internal control signal line 92b. As a result, the light emitting state of the light source module 11 is controlled according to the control signal.

The control signal supplied to the light source module 11 is transmitted to the light source module 11 in the subsequent stage next to the light source module 11 via the first feed internal control signal line 92g, which is one of the internal conductive lines 92. As a result, the light emitting state of the light source module 11 in the subsequent stage is also controlled according to the control signal. That is, since the two light source modules 11 in the front stage and the rear stage are controlled by the same control signal, the light emitting state is controlled in the same manner.

Further, when connecting a plurality of lighting fixtures 1, the two adjacent lighting fixtures 1 are not only connected by the connecting power supply line 93a, which is one of the connecting conductive lines 93, as described above, but also connected. It is also connected by the connection control signal line 93b, which is one of the other conductive lines 93.

The connection control signal line 93b is connected to the second feed internal control signal line 92h, which is one of the internal conductive lines 92. Specifically, the connector 93b1 is provided at the end of the connection control signal line 93b, and the connector 92h1 is provided at the end of the second feed internal control signal line 92h. By connecting the connector 93b1 and the connector 92h1, the connection control signal line 93b and the second feed internal control signal line 92h are connected.

As a result, the control signal supplied to the light source module 11 in the subsequent stage is transmitted to the adjacent lighting fixture 1 connected via the second feed internal control signal line 92h and the connection control signal line 93b.

Further, the input power supply power line 91a and the input control signal line 91b, which are the input conductive lines 91, are pressed by the tension stop member 81 provided on the input portion side of the lighting fixture 1. Similarly, the connecting power line 93a and the connecting control signal line 93b, which are the connecting conductive lines 93, are pressed by the tension stop member 81 provided on the output portion side of the luminaire 1.

Then, in the present embodiment, the input conductive wire 91 and the connecting conductive wire 93 pressed by the tension stop member 81 and the internal conductive wire 92 are connected inside the tension stop member 81.

With this configuration, only the frame 20 can be removed without removing the tension stopper member 81. As a result, the lighting fixture 1 can be easily repaired and parts replaced.

Here, the case of connecting a plurality of lighting fixtures will be described with reference to FIGS. 16 and 17. FIG. 16 is a diagram for explaining a connection method when connecting a plurality of conventional lighting fixtures 1X. FIG. 17 is a diagram for explaining a connection method when a plurality of lighting fixtures 1 according to an embodiment are connected.

As shown in FIG. 16, when a plurality of conventional lighting fixtures 1X are connected, the input conductive wire 91X drawn from one of the two adjacent lighting fixtures 1X is inside the other lighting fixture 1X. The input conductive wire 91X drawn out from one of the luminaires 1X is connected to the internal conductive wire 92X of the other luminaire 1X.

On the other hand, as shown in FIG. 17, when connecting a plurality of lighting fixtures 1 according to the present embodiment, a connecting conductive wire 93 for connecting two adjacent lighting fixtures 1 is separately prepared. Inside each of the two adjacent lighting fixtures 1, the internal conductive wire 92 and the connecting conductive wire 93 are connected. That is, each of the input / output portions of each lighting fixture 1 is connected.
