Therefore, the cover 112 is formed of a material having light transmittance. Specifically, the cover 112 is formed using glass, acrylic resin, or the like.

  On the other hand, the base portion 111 can be formed using various materials such as a metal material and a resin material. However, in order to reduce the weight, it is preferable to form the resin material. Further, when used outdoors as in the present embodiment, it is preferable to form the base portion 111 using an ASA resin having excellent weather resistance.

  The light source unit 120 includes a light bulb 121 in which an LED chip as a light source is arranged, and a socket 122 to which the light bulb 121 is attached. In this embodiment, the socket 122 is attached to the upper portion of the base 111 with the receiving opening opened upward. The light source unit 120 is formed by attaching the base of the light bulb 121 to the socket of the socket 122.

  In addition, in the present embodiment, the light bulb 121 including the LED chip is illustrated, but an incandescent light bulb can be used, and a light emitting element such as a semiconductor light source can be used as a light source.

  A switch 130 is formed on the base 111, and the lighting device can be switched on and off by operating the switch 130. It should be noted that power is supplied to the light source unit 120 by the power cord 140.

  Further, in this embodiment, the base portion 111 includes a flange portion 113 formed at the lower end, and the support portion 150 is connected to the flange portion 113. In addition, the flange portion 113 is formed with a pair of through holes 113a.

  The support part 150 has a spike part 151 penetrating the installed part 41, and the spike part 151 is continuously provided so as to project downward on the lower surface side of the flange part 113. In the present embodiment, the spike portion 151 is formed in a tapered shape in which the tip side is narrower than the root side (flange portion 113 side), and the cross-sectional shape is a cross shape.

  The spike portion 151 can also be formed using various materials such as a metal material and a resin material, but it is preferable to use an ASA resin in consideration of weight reduction and outdoor use.

  The spike portion 151 (support portion 150) may be formed as a separate component from the flange portion 113 (main body portion 100), or may be integrally formed with the flange portion 113. When the spike portion 151 is formed as a separate component from the flange portion 113, the spike portion 151 is fixed to the flange portion 113 using a fixture such as a bolt.

  When the existing lighting device 10A having such a configuration is used as it is, the main body 100 is supported on the ground (installed part 41) by penetrating the spike part 151 into the ground (in the installed part 41). Will be.

  In addition, as described above, the through hole 113a is formed in the flange portion 113 of the existing illumination device 10A. An anchor member such as a peg is inserted into the through hole 113a when the existing lighting device 10A is normally used.

  That is, in the existing lighting device 10A, an anchor member such as a peg is inserted into the through hole 113a with the spike portion 151 penetrating into the ground and the main body portion 100 is fixed to the ground, and penetrates into the installed portion 41. It is configured to be able to. An anchor member such as a peg is used to firmly fix the main body 100 to the ground, for example, when the main body 100 is slightly wobbled only by penetrating the spike 151 into the ground. ..

  As described above, the through hole 113a is a hole provided to enable the lighting device 10A to be more firmly supported on the ground by the anchor effect of the anchor member, and the existing lighting device 10A shown in the present embodiment is The lighting device has a relatively high degree of freedom of installation location.

  However, even if the existing lighting device 10A has a relatively high degree of freedom of installation location, if it is installed on the ground having relatively low hardness or on snow, its own weight (the weight of the existing lighting device 10A is reduced). ), The main body 100 may be tilted. In addition, the weight of the lighting device may cause the existing lighting device 10A to sink into snow or dirt (in the installed portion 41).

  In this way, even with the existing lighting device 10A having a relatively high degree of freedom of installation location, it is difficult to install it on the ground or snow having a relatively low hardness.

  Therefore, in the present embodiment, the illumination device 10 that can be installed on the ground or the snow having a relatively low hardness is provided.

  Specifically, the lighting device 10 includes the subsidence suppressing unit 160. The subsidence suppressing portion 160 contacts the installation surface 41a of the installed portion 41 in a state where the spike portion 151 penetrates the installed portion 41, and suppresses the subsidence into the installed portion 41.

  In the present embodiment, the subsidence suppressing unit 160 is a separate component from the existing lighting device 10A, and the subsidence suppressing unit 160 is attached to the existing lighting device 10A to form the lighting device 10 (see FIG. 6).

  The subsidence suppressing portion 160 is formed of a steel plate, SUS or the like, and has a substantially disc shape. Although it is possible to reduce the weight by forming the subsidence suppressing portion 160 using a resin material, it is preferable to use a steel plate, SUS, or the like to suppress deformation during carrying. ..

  In the present embodiment, the subsidence suppressing portion 160 includes a strip-shaped portion 161 that is substantially annular in a plan view, and a pair of mounting pieces 163 that are continuously provided inside the strip-shaped portion 161 and project toward the center. ing. A through hole 162 extending along the strip-shaped portion 161 is formed on the inner peripheral side of the strip-shaped portion 161. The strip-shaped portion 161 may be formed in a substantially C shape in plan view with a part cut away.

  A through hole 163a is formed on the tip side of each mounting piece 163. That is, a pair of through holes 163a are formed in the subsidence suppressing portion 160. The pair of through holes 163a are formed at positions corresponding to the pair of through holes 113a formed in the existing illumination device 10A described above. Then, the subsidence suppressing portion 160 is attached to the existing illumination device 10A by fastening the bolts 171 and the nuts 172 in a state where the through holes 163a are communicated with the through holes 113a. By doing so, the illumination device 10 according to the present embodiment is formed.

  Here, in the present embodiment, the center of the subsidence suppressing section 160 and the center of the main body section 100 are substantially aligned with each other in a plan view with the subsidence suppressing section 160 attached to the existing illumination device 10A. The outer diameter of the belt-shaped portion 161 is made larger than the outer diameter of the main body portion 100.

  It is preferable that the outer diameter of the band-shaped portion 161 be larger than 1 times and not larger than 3 times the outer diameter of the main body 100. If it is 1 time or less, the subsidence of the main body 100 cannot be suppressed, and if it is more than 3 times, the subsidence of the main body 100 can be suppressed, but the weight increases and it becomes difficult to carry. This is because. Further, in order to more surely suppress the sinking of the main body 100 and facilitate the carrying, the outer diameter of the belt-shaped portion 161 is set to be 1.5 times or more and 2 times or less the outer diameter of the main body 100. Is more preferable.

  In addition, in the present embodiment, the inner diameter of the belt-shaped portion 161 (the diameter of the through hole 162) is also larger than the outer diameter of the main body portion 100. Therefore, the illumination device 10 has a shape in which the entire periphery of the main body 100 is surrounded by the band-shaped portion 161 in a plan view.

  As described above, in the present embodiment, the subsidence suppressing portion 160 is arranged such that the entire outer edge 160a is located outside the main body portion 100 in a plan view.

  When the illuminating device 10 having such a configuration is installed on the installed portion 41, the lower surface of the sinking suppression portion 160 comes into contact with the installation surface 41 a of the installed portion 41. Therefore, the contact area with the installation surface 41a becomes large as compared with the case where the existing illumination device 10A is installed as it is. As described above, when the contact area with the installation surface 41a increases, the force pressed by the main body 100 is dispersed, and the pressing force applied per unit area decreases. As a result, it is possible to prevent the main body 100 from sinking into the installed portion 41 due to its own weight, and it is possible to install the main body 100 on the ground, snow, or the like having a relatively low hardness.

  As described above, the illumination device 10 according to the present embodiment is installed on the ground as shown in FIG. 8A when the snow is not accumulated in the summer, and when the snow is accumulated in the winter, as shown in FIG. It can be installed on snow, as shown in b). Note that in FIG. 8A, the ground corresponds to the installed portion 41 on which the lighting device 10 is installed, and in FIG. 8B, the snow-covered portion on the ground is the installed surface on which the lighting device 10 is installed. It corresponds to the installation unit 41.

  As described above, the lighting device 10 according to the present embodiment includes the main body 100 having the light source 121, the support portion 150 having the spike portion 151 penetrating the installed portion 41 and supporting the main body portion 100. , Are provided. Further, the lighting device 10 contacts the installation surface 41 a of the installed portion 41 with the spike portion 151 penetrating the installed portion 41, and suppresses the sinking into the installed portion 41. Is equipped with. The subsidence suppressing portion 160 is arranged such that the outer edge 160a is located outside the main body portion 100 in a plan view.

  By doing this, the contact area with the installation surface 41a in a state where the illumination device 10 is installed on the installation target 41 becomes large, so that the force with which the installation surface 41a is pressed by the main body 100 is dispersed, and the installation surface 41a is distributed. The pressing force applied per unit area can be reduced. As a result, it is possible to prevent the main body 100 from sinking into the installed portion 41 due to its own weight, and it is possible to install the main body 100 on the ground, snow, or the like having a relatively low hardness.

  As described above, according to the present embodiment, it is possible to obtain the lighting device 10 that can further improve the degree of freedom of the installation place.

  In addition, in the present embodiment, the subsidence suppressing portion 160 includes the strip-shaped portion 161 arranged so as to surround the main body portion 100 in a plan view, and along the strip-shaped portion 161 on the inner peripheral side of the strip-shaped portion 161. A through hole 162 that extends is formed.

  This makes it possible to secure the contact area between the subsidence suppressing section 160 and the installation surface 41a while suppressing an increase in the weight of the subsidence suppressing section 160. Further, when the contact area with the installation surface 41a is the same, the size (outer diameter, etc.) of the subsidence suppressing portion 160 is larger than in the case where the through hole 162 is not provided, so that the body portion 100 is prevented from falling more. It can be surely suppressed. That is, the main body 100 can be supported more stably.

  Further, in the present embodiment, the subsidence suppressing portion 160 is formed as a member different from the main body portion 100 and the supporting portion 150.

  With this, the subsidence suppressing section 160 can be attached to and detached from the main body section 100 and the supporting section 150, and the subsidence suppressing section 160 can be selectively used. Further, the existing lighting device 10A can be used to form the lighting device 10 that can be installed on the ground having a relatively low hardness, on snow, or the like. By doing so, it is possible to obtain the lighting device 10 that is easier and cheaper and can improve the degree of freedom of the installation place.
