The trapezoidal shape and the outer shape in the left-right direction are formed into a bowl shape that is a U-shape, and the hollow portion 24 is formed. The lower ends of the partition plates 22 and 23 have a constant height to form an outer peripheral portion 25, and strength retaining ribs 26 are disposed in the hollow portion 24 so as to partition the hollow portion 24.

  FIG. 3 is a perspective view from above showing the bottom plate. The bottom plate 5 is provided with vertical plates 52 and 53 on the outer edges of the flat plate-like lower plate 51 in the front-rear direction and the left-right direction, and has a bowl-like shape. Two mounting portions 55 each having two bolt holes 54 for mounting are provided.

  4 and 5 are perspective views of the bottom side showing the attachment of the case main body 2 and the bottom plate 5 to the cover 1. In FIG. 4, the cover 1 has the front and rear inclined surfaces 11 and the upper plate 12 to the case main body 2 as shown in FIG. Light paths 111 and 121 that transmit light from the case body 2 or the case body 2 are provided, and a space 15 is formed by the inclined surfaces 11 and 13 and the upper plate 12. At the upper edge of the space 15, a notch 16 for attaching a bottom plate is drilled, and a screw hole 17 in which a screw thread is threaded is formed in the bottom of the notch 16. The lower surface 14 of the cover 1 has a constant height, and is stable when installed on the road surface using the bolt holes 132. In the space 15, the case main body 2 in which the device 6 including the solar cell 3, the light emitting body 4, and the like is arranged in a part of the hollow portion 24 partitioned by the ribs 26 is arranged.

  Further, in FIG. 5, the bottom plate 5 is attached to the cover 1 so as to cover the hollow portion 24 of the case body 2. The bottom plate 5 is attached upside down from the state shown in FIG. The notch portion 16 provided on the lower surface of the cover 1 has a shape into which the attachment portion 55 of the bottom plate 5 can be inserted, and the attachment portion 55 is inserted into the notch portion 16 and the bolt inserted into the bolt hole 54, Fastening means T such as a screw is screwed into a screw hole 17 formed in the bottom of the notch 16 so that the cover 1 and the bottom plate 5 are fixed. The cover 1 and the bottom plate 5 are fixed, the case body 2 is held by the cover 1 and the bottom plate 5, and the lower plate 51 of the bottom plate 5 is in contact with the entire circumference of the outer peripheral portion 25 of the case body 2. The The lower surface of the lower plate 51 of the bottom plate 5 is approximately the same as the height of the lower surface 14 of the cover 1 in the attached state.

  Further, as shown in FIG. 6, the water blocking material 7 is sandwiched between the lower plate 51 of the bottom plate 5 and the outer peripheral portion 25 of the case body 2 in FIG. 5, and the lower plate 51 and the outer peripheral portion 25 are interposed via the water blocking material 7. You may make it contact. By providing the water stop material 7, the water stop material 7 is pressed against the lower plate 51 and the outer peripheral portion 25 by tightening the fastening means T, and the device 6 is more reliably protected from water and dust. The water stop material 7 is not particularly limited as long as it has high resistance to salt water, but if it is formed using an elastic body that generates deformation and repulsion by tightening the fastening means T. Since the minute gap between the lower plate 51 and the outer peripheral portion 25 can be closed, the device 6 can be protected over a long period, which is preferable.

  Examples of the elastic body used to form the water-stopping material 7 include natural rubber, butadiene styrene rubber, neoprene, butadiene acrylonitrile rubber, chloroprene polymer, butyl rubber, ethylene propylene terpolymer, and urethane resin that are highly resistant to salt water. , Using polyisobutylene resin, polyethylene resin, ethylene vinyl acetate copolymer, silicone resin, soft and hard vinyl chloride resin, elastic materials made of various synthetic rubbers such as elastomers, synthetic resins, etc. Good. In addition, it is preferable to use a double-sided tape having an adhesive layer formed on both sides using an acrylic resin or the like as a base material, which can prevent salt water and dust from entering more reliably.

  FIG. 7 shows an example of a state after the fastening means T is screwed, in which A) is a cross-sectional view taken along line AA in FIG. 5, and B) is a cross-sectional view taken along line BB. 1), the cover 1 covering the translucent case main body 2 is provided with a light passage 121 in the upper surface plate 21 portion of the case main body 2 so that the solar cell 3 accommodated in the case main body 2 receives sunlight. The incident is not disturbed. In the hollow portion 24 of the case body 2, devices such as the solar cell 3, the light emitter 4 attached to the substrate 61, and the power storage means 62 are accommodated, and the outer peripheral portion 25 of the case body 2 contacts the lower plate 51 of the bottom plate 5. By doing so, intrusion of salt water, dust, or the like is prevented, and the device stored in the hollow portion 24 is protected. Since the ribs 26 are erected in the hollow portion 24 from the upper surface plate 21, the strength against impact and load from above such as riding on the vehicle is increased. Further, the upper surface plate 21 of the case body 2 is provided with a convex portion 211 and can be fitted to the light path 121 of the cover 1, so that the case body 2 can be easily positioned and the case body 2 can be shaken. Can be suppressed.

2), the cover 1 is further provided with light paths 111 on the inclined surface 22 portions provided on the left and right sides of the case body 2 so that the light emission from the light emitter 4 in the case body 2 is not hindered. ing. The light emitter 4 is provided horizontally in the opposite direction, and the lights L1 and L2 emitted from the light emitter 4 pass through the translucent case body 2 and the light passage 111 and are emitted in the left and right directions. . Therefore, when the self-luminous indicator lamp 10 is installed on the quay, wharf, jetty, etc., if the inclined surface 22 of the case body 2 is installed facing the ocean side and the land side, light is emitted toward the ocean side and the land side. This makes it possible to clarify the boundary between the ocean and land.
In addition, in the said form, the same thing is used for the light-emitting body 4 of the ocean side, and the light-emitting body 4 of the land side, and the elevation angle and the wide angle of those lights are made the same, However, Visibility from the ocean side Since the visibility from the land side is not always the same, it is preferable to change them appropriately. For example, the light from the light emitter on the ocean side may be made wider than the light on the land side, the emission color may be changed, the number may be changed, and the elevation angle may be changed as necessary. Furthermore, the visibility of the self-luminous marker lamp 10 may be further improved by providing a concave lens in front of the ocean-side light emitter 4 and expanding the light emitted from the light emitter 4.

  With the above-described structure, the case body 2 is held by the cover 1 and the bottom plate 5. However, when holding the case body 2, it is not necessary to directly drill and fix a screw hole or the like in the case body 2, and due to temperature changes. It is possible to prevent the case main body 2 from being cracked or deformed due to expansion or contraction of the case main body 2 or stress concentration on the screw hole or the like due to the vehicle getting on. In addition, since the device 6 is protected by the contact between the outer peripheral portion 25 of the case body 2 and the lower plate 51 of the bottom plate 5, even when maintenance of the device 6 becomes necessary, the device 6 is inserted into the bolt hole 132 and automatically. The device 6 can be easily taken out and maintained by removing the bolt for fixing the light-emitting marker lamp 10 to the road surface and further removing the fastening means T screwed into the screw hole 17 of the cover 1.

  Further, by using the fastening means T, the force with which the lower plate 51 of the bottom plate 5 comes into contact with the outer peripheral portion 25 of the case main body 2 can be adjusted by the tightening torque of the fastening means T, and water or dust can be applied to the hollow portion 24. Intrusion can be prevented more reliably. In order to further improve the water stop effect, the notch 16 of the cover 1 may be filled with a sealing agent after the fastening means T is screwed. Further, the bottom plate 5 is formed into a bowl shape by the vertical plates 52 and 53, and a mounting portion 55 having a bolt hole 54 formed at the upper end of the vertical plate 53 is provided, so that the height of the vertical plates 52 and 53 is increased. Thus, the mounting bolt or the like does not protrude from the bottom surface 14 of the cover 1 and the space in the vertical direction of the hollow portion 24 can be widened. Further, even when the self-luminous marker lamp 10 is fixed to the ground surface or the like by using an adhesive without using the bolt holes 132, the lower surface can be flattened and the adhesion can be made smooth. Further, the cover 1 and the bottom plate An anchor effect due to a gap with 5 can also be expected.

  It is preferable that the cover 1 is formed of a metal material because it can resist an impact and a load caused by riding on a vehicle or mischief, and can increase the effect of the cover 1. The formation may be performed by assembling a plurality of parts made of metal, etc., but by using a cast product or a die-cast product using aluminum, zinc, etc., a complicated shape as described above can be easily formed integrally. This is preferable. In addition, because it is installed on quay, wharf, jetty, etc., in consideration of rust prevention surface, polycarbonate, polyethylene terephthalate, polyethylene, polyethylene naphthalate, polyphenylene sulfide, polyamide, polyurethane, polymethacrylate, polypropylene, acrylic resin, poly A molded article made of a synthetic resin material such as vinyl chloride or ABS may be used, but among them, a polycarbonate that is less susceptible to cracking or deformation due to impact or load can be suitably used.

  The case body 2 is not particularly limited as long as it is translucent. Glass, tempered glass, polycarbonate, polyethylene terephthalate, polyethylene, polyethylene naphthalate, polyphenylene sulfide, polyamide, polyurethane, polymethacrylate, polypropylene, Transparent synthetic resin materials such as acrylic resin, polyvinyl chloride, and ABS may be used. However, since it is possible to ride on the vehicle, etc., polycarbonate that has high transparency and is resistant to cracking and deformation against impact and load is suitable. Can be used. The molding may be performed by fitting or bonding a member made of the above material to the shape of the case main body, but there is a possibility that a gap may be generated due to an impact or a load caused by riding on the vehicle. It is preferable to form integrally by vacuum forming or the like.

The light-emitting body 4 is a light-emitting diode having high brightness and a long lifetime. Further, the directivity angle may be expanded by using a wide-angle type light emitting diode.

  Since the bottom plate 5 is fixed to the cover 1 and holds the case body 2, it may be formed using a metal material having high strength. Forming may be performed by casting, die casting, etc., but impregnation treatment for cutting or waterproofing of convex parts such as molded products by casting or die casting by cutting a metal plate into an appropriate shape and bending it. Such post-processing is not necessary, and the combination with the case main body 2 can reliably prevent water and dust from entering the hollow portion 24 of the case main body 2. In addition, because it is installed on quay, wharf, jetty, etc., in consideration of rust prevention surface, polycarbonate, polyethylene terephthalate, polyethylene, polyethylene naphthalate, polyphenylene sulfide, polyamide, polyurethane, polymethacrylate, polypropylene, acrylic resin, poly Molded products of synthetic resin materials such as vinyl chloride and ABS may be used, but the function of the self-luminous indicator lamp 10 can be extended over a long period of time by using polycarbonate that is not easily cracked or deformed due to impact or load. This is preferable because it can be maintained.

  As described above, the sealing agent for filling the notch portion 16 of the cover 1 used for improving the water-stopping effect in the case body 2 is that the cover 1, the case body 2 and the bottom plate 5 are made of a polycarbonate resin material. Assuming the case where it is formed, it is preferable to use an alcohol-type silicone resin-based sealing agent that is unlikely to cause adverse effects such as causing cracks in the polycarbonate resin.
