It can prevent infiltration into areas where electrical components are densely packed. Therefore, it is possible to improve the waterproofing effect against rainwater intrusion into the area where electrical components are densely packed.

Next, a structure for attaching the lighting device 1 to the gatepost 50 will be described. Referring again to FIG. 6, the mounting structure includes a mounting fitting 60, an engagement recess 56, and a gate post mounting piece 57. FIG. 10 is a perspective view of the gatepost 50 to which the mounting bracket 60 is attached, and FIG. 11 is a perspective view of the gatepost 50 to which the light source 20 is attached. As shown in FIG. 10, the mounting bracket 60 has a first flat plate part 61, a second flat plate part 62, and a connecting part 63. The first flat plate portion 61 is fixed to the gate post 50 with screws 64 with its longitudinal direction substantially aligned with the X direction.

As shown in FIG. 6, the engagement recess 56 and the gate post attachment piece 57 are provided in the main body 5 of the case 2. Specifically, the engagement recess 56 is provided above the orthogonal protrusion 3 and on the gatepost 50 side in the Y direction, and opens downward in the Z direction. The engagement recess 56 is an engagement recess that protrudes from the upper side of the orthogonal protrusion 3 on the gatepost 50 side in the Y direction toward the gatepost 50 in the Y direction, and then bends downward in the Z direction and extends downward in the Z direction. It has a stopper piece 67. The engagement recess 56 is defined by a side surface 69 of the orthogonal protrusion 3 on the gate post side in the Y direction and a locking piece 67 .

Moreover, the gate post attachment piece 57 protrudes from the lower side of the orthogonal direction protrusion 3 toward the lower side in the Z direction. The gate post attachment piece 57 has a flat plate portion 57a and a connecting portion 57b. The flat plate portion 57a is located closer to the gatepost 50 in the Y direction than the side surface of the orthogonal protrusion 3 on the gatepost 50 side in the Y direction, and is located below the lower surface of the orthogonal protrusion 3 in the Z direction. The flat plate portion 57a extends substantially parallel to the XZ plane. Further, the connecting portion 57b connects the lower side of the orthogonal protruding portion 3 and the upper end of the flat plate portion 57a, and extends in the X direction. As shown in FIG. 6, the upper end of the second flat plate part 62 in the Z direction is fitted into the engagement recess 56 from below, and as shown in FIG. By fixing to the gatepost 50, the lighting device 1 is fixed to the gatepost 50.

FIG. 12 is a diagram illustrating a suitable wiring structure in the lighting device 1. In the example shown in FIG. 12, the cable that supplies power from the commercial power source enters the basement from the house, extends upward in the Z direction inside the pillar section 52 of the gatepost 50, and then connects to the EE (Electric Eye) switch. (Automatic flasher) 72 is electrically connected. The wiring 73 indicates a wiring portion extending upward in the Z direction inside the pillar portion 52 of the gatepost 50. The EE switch 72 includes an illuminance sensor and the like, and automatically turns on when it gets dark and turns off automatically when it gets bright.

A wiring 74 that electrically connects the EE switch 72 to the power supply device 30 extends downward in the Z direction inside the column portion 52 of the gatepost 50, and extends outside the gatepost 50 through a hole 75 provided in the gatepost 50. Further, the wiring 77 extending outward extends to a bush 78 (see FIG. 2) attached to the case 2 while being covered with a pipe-like covering part (not shown), and then passes through the bush 78 into the case 2. and is electrically connected to the power supply device 30.

In this way, power from a commercial power source is connected to the power supply device 30, and DC power appropriately converted by the power supply device 30 is supplied to the LED 22 (see FIG. 5). In this embodiment, the wiring from the commercial power source is electrically connected to the power supply device 30 after passing through the EE switch 72, so that the lighting device 1 can be automatically turned on or off depending on the darkness. . Note that instead of the EE switch, a switch that allows a person to select whether or not to turn on the lighting device may be used.

As described above, the lighting device 1 is attached above the ground below the gate post 50 having one or more pillar parts 52 extending from the ground in the X direction. In addition, the lighting device 1 includes an orthogonal protruding portion (protruding from the gate post 50 to a location away from the gate post 50 in the Y direction perpendicular to both the width direction (X direction) and the vertical direction (Z direction) of the gate post 50. A case 2 including an outer protrusion 3 is provided. Furthermore, the lighting device 1 includes a light source 20 that is disposed within the case 2 at a position away from the gatepost 50 in the Y direction and emits light upward in the Z direction.

Therefore, the illumination light emitted upward from the light source 20 is less likely to be blocked by the column part 52 of the gatepost 50 or the post 53, and the illumination light can reliably illuminate the upper part. In addition, since the light source 20 installed below the gatepost 50 and located away from the gatepost 50 in the Y direction emits light upward, the illumination light from the light source 20 illuminates the gatepost 50. The upper side of the pillar part 52 can be easily illuminated, and the shadow of the pillar part 52 of the gatepost 50 can be highlighted. Therefore, the effect of illumination light can be enhanced. Furthermore, since the lighting device 1 is attached above the ground on the gatepost 50, it is possible to prevent the lighting device 1 from deteriorating due to rainwater on the ground.

The lighting device 1 also includes a power supply device 30 that converts input power and generates output power to be supplied to the light source 20. Alternatively, the outer protrusion may be an orthogonal protrusion 3 that extends from the gate post 50 in approximately the Y direction. Further, the case 2 may include a vertical protrusion 4 having a substantially L-shaped side surface and protruding upward in the Z direction from the opposite side of the orthogonal protrusion 3 from the gate post 50 side. Further, the power supply device 30 is housed in a power supply housing chamber 3a provided in the orthogonal protrusion 3, while the light source 20 is housed in a light source housing chamber 4a provided in the vertical protrusion 4. Good too.

According to this configuration, the light source 20 can be arranged to overlap the power supply device 30 in the Z direction. Therefore, the lighting device 1 can be made to look more compact compared to the case where the light source and the power supply device are arranged so as to overlap in the Y direction, and a stylish lighting device 1 can be realized.

Further, as shown in FIG. 13, that is, a perspective view of the lighting device 1 installed on the gatepost 50 when viewed from a direction different from FIG. It may have a protrusion piece 81 that protrudes upward from the end on the side far away in the Y direction.

According to this configuration, part of the light that is emitted upward from the lighting device 1 and spreads to the side opposite to the gatepost 50 side in the Y direction can be reflected by the protruding piece 81 toward the gatepost 50 side in the Y direction. Therefore, the illumination light can be directed toward the gatepost 50, the post 53, and the delivery box 59, and can be illuminated by the light reflected from the protruding piece 81. Therefore, the shadow of the column part 52 of the gatepost 50 can be made more prominent, the effect of illumination light can be further enhanced, and the mailbox 53 and the delivery box 59 can be illuminated with brighter light.

Moreover, even if the light source 20 is not positioned with high precision, it is possible to suppress the illumination light from spreading to the side opposite to the gate post 50 side in the Y direction, and the degree of freedom in the arrangement of the light source 20 can be increased. Moreover, since the illumination light can be suppressed from spreading to the side opposite to the gatepost 50 side in the Y direction, people are less likely to feel dazzled by the illumination light from the illumination device 1.

Further, in the lighting device 1, the first flat plate portion 61 is attached to the gate post 50, and the upper end portion 62a is positioned above the first flat plate portion 61 in a state where the first flat plate portion 61 is attached to a predetermined position of the gate post 50. and a connecting portion 63 that connects the first flat plate portion 61 and a portion of the second flat plate portion 62 other than the upper end 62a. A mounting fitting 60 may also be provided. Further, the orthogonal direction protrusion 3 may have an engagement recess 56 that opens downward in the Z direction on the gate post 50 side in the Y direction, and may also have a gate post mounting piece 57 that projects downward in the Z direction. . Further, the upper end portion 62a may be engaged with the engagement recess 56, and the gate post attachment piece 57 may be fastened to the gate post 50 with a screw (fastening means) 71.

According to this configuration, the upper end 62a of the mounting bracket 60 attached to the gate post 50 is inserted into the engagement recess 56 provided on the gate post 50 side in the Y direction of the orthogonal direction protrusion 3 and opened downward. It is inserted and locked in place. Therefore, when a person views the lighting device 1 from above, it becomes difficult for a person to visually recognize the attachment point of the lighting device 1 to the gatepost 50. Therefore, the lighting device 1 can be made stylish and aesthetically pleasing. Furthermore, since the gatepost mounting piece 57, which is present on the lower side of the lighting device 1 and is difficult for people to see, is fixed to the gatepost 50 with the screw 71, the lighting device 1 can be securely fixed to the gatepost 50.

Note that the present disclosure is not limited to the above-described embodiments and their modifications, and various improvements and changes can be made within the scope of the claims of the present application and their equivalents.

For example, in the embodiment described above, a case has been described in which the light emitting section is composed of one or more LEDs 22, but the light source may be composed of one or more semiconductor laser elements. Alternatively, the light emitting section may be composed of one or more solid state light emitting elements such as one or more organic EL (Electro Luminescence) elements or one or more inorganic EL elements. Further, the light emitting section may be composed of an incandescent lamp.

In addition, although the case where the outer protrusion is the orthogonal protrusion 3 extending in the Y direction has been described, the outer protrusion only needs to extend in a direction that includes the orthogonal extension component, and with respect to the orthogonal direction. It may also extend in a direction that is inclined.

Furthermore, although the case 2 includes the vertical protrusion 4, the case does not need to include the vertical protrusion. Further, a case has been described in which the vertical protrusion 4 has the protrusion piece 81 that protrudes upward from the end portion of the upper surface 88 on the side away from the gatepost 50 in the Y direction. However, the vertically protruding portion does not need to have a protruding piece that protrudes upward at the end portion of the upper surface of the vertically protruding portion on the side away from the gate post 50 in the Y direction.

In addition, by locking the upper end 62a of the mounting bracket 60 fixed to the gate post 50 from below into the engagement recess 56 provided on the gate post 50 side in the Y direction of the case 2 and opening downward, the lighting The case where the device 1 is fixed to the gatepost 50 has been described. However, the case does not need to have an engagement recess that opens downward; for example, the lighting device may be fixed to the gatepost by fixing a protruding piece that projects upward in the case to the gatepost. .
