FIG. 7 is a cross-sectional view showing the state of the outer frame during construction.

  In the drawings, 1 is a main body. As shown in FIGS. 1 and 2, the main body 1 is provided with a colorless and transparent cover material 12 so as to block the upper surface of the main body frame 11 opened upward, and a step is provided on the side edge of the cover material 12. At the same time, a fixing member 13 that is fitted from above is provided at the step, and the fixing member 13 is fixed to the main body frame 11 by bolts (not shown), so that the cover member 12 is fixed to the main body frame 11. The fixing member 13 is attached over the entire periphery of the side edge of the cover member 12. The main body frame 11 may be a synthetic resin injection-molded product, but an aluminum casting is used in the present embodiment. The cover material 12 is a transparent polycarbonate resin injection molded product. The fixing material 13 is an aluminum casting.

  A light source 16, which is a chip-type light emitting diode, is attached to the light emitting substrate below the lower surface of the cover member 12. The optical axis of the light source 16 is set to a direction in which the cover material 12 is disposed or a direction substantially perpendicular to the ground surface at the time of installation. A power storage unit 15, which is a lead storage battery, is provided between the cover material 12 and the light emitting substrate, and the electric power generated by the solar cell 14 provided at an appropriate position below the cover material 12 is stored, so that the nighttime In FIG. 2, the power stored in the light source 16 is supplied to cause the light source 16 to emit light.

  Here, the light source 16 uses a chip-type light emitting diode, so that the viewing angle of light emission can be set to 80 to 160 ° which is much larger than that of the bullet type, and the optical axis of the light source 16 is the cover material 12 or Even if it is substantially perpendicular to the ground surface at the time of installation, the light from the light source 16 can be seen at least from the direction of 40 to 80 ° which is half the viewing angle when viewed from obliquely above, Compared with the case of using a type of light emitting diode having a viewing angle of about 20 to 40 °, the visibility from all directions is improved.

  Further, side wall portions 18 are provided on both sides of the light source, and the side wall portions 18 are provided so as to surround the light source 16. The side wall portion 18 extends to near the lower surface of the cover material 12, and when viewed from above the cover material 12, it appears that the portion surrounded by the side wall portion 18 of the cover material 12 emits light. The side wall 18 is a reflector such as a mirror body. By making the side wall portion 18 a reflecting plate, the light from the light source 16 is guided to the cover material 12 without waste, and the light emission luminance of the cover material 12 is increased, and the visibility from above is further enhanced.

  A light diffusion sheet 17 is attached to the lower surface of the cover material 12 so as to be surrounded by the side wall portion 18. The light emitted from the light source 16 by the light diffusion sheet 17 is diffused when it is transmitted, so that the light emitted from the cover material 12 is emitted to the entire light diffusion sheet 17 with uniform luminance. In addition, the visibility from all directions can be improved, and the stimulation when the light emitted from the light source 16 is dispersed and visually recognized can be reduced.

  The light diffusing sheet 17 can set the transmittance by selecting the material, amount, or thickness of the light diffusing substance, but if the light transmittance is 50 to 80% or more, the diffused light L2 Therefore, it is possible to achieve both visibility from all directions and sufficient presence evoke by the light from the light source 16.

  Furthermore, the light diffusion on the lower surface of the cover material 12 is not limited to that by the light diffusion sheet 17, and the light diffusion material is blended and molded in a range where light from the light source 16 on the lower surface of the cover material 12 is transmitted. Light diffusion can be performed by this method.

  2 is an outer frame. When the main body 1 in which the main body frame 11, the cover material 12, and the fixing material 13 are integrated is housed in the outer frame 2, the upper surface of the fixing material 13 becomes substantially the same height as the upper end surface of the side wall of the outer frame 2. The outer frame 2 uses an aluminum casting.

  3 is a sealing material. When the sealing material 3 is filled in the gap between the main body 1 and the outer frame 2, it is filled so as to close the gap between the outer peripheral surface of the side wall of the fixing material 13 and the main body frame 11 and the inner peripheral surface of the side wall of the outer frame 2. In this case, since the main body 1 is fixed to the outer frame 2 by the adhesive force of the sealing material 3, it is not necessary to use a fastening member such as a bolt or a screw. The sealing material 3 is filled so that the upper surface of the fixing material 13, the upper end surface of the side wall of the outer frame 2, and the upper surface of the sealing material 3 are substantially flush when filled. Filling the sealing material 3 so that they are flush with each other does not form a recess for storing sand, dust, or the like in the upper part of the gap between the fixing material 13 and the outer frame 2. Further, it is possible to prevent the seal material 3 from coming into contact with the wear or damage. The material used for the sealing material 3 is not particularly limited as long as it is an indeterminate sealing agent that is in a paste form before filling and is cured after filling to become a rubber-like material. Silicone and the like are preferable, but other sealing agents such as silicone, polysulfide, acrylic urethane, polyurethane, acrylic, and butyl rubber can be used.

  Further, when removing the main body 1 filled with the sealing material 3 in the gap with the outer frame 2 from the outer frame 2, the sealing material 3 fulfills the sealing function because the sealing material 3 is cut out with a cutter or the like. Since it is preferable to be filled to such a depth that it can be easily cut off, the outer frame 2 is formed so that the gap between the main body 1 and the outer frame 2 has a groove shape with an appropriate depth. .

  Further, as shown in FIG. 3, when the main body 1 is fixed to the outer frame 2 using a fastening member such as a bolt or a screw, the fixing screw 4 is screwed into the outer frame 2 from above the fixing frame 13 and fixed. . At this time, an insertion portion of the fixing screw 4 of the fixing frame 13 is formed to be lower than other upper surface portions so that the head of the fixing screw 4 does not protrude upward from the upper surface of the fixing frame 13. Since the head of the fixing screw 4 is fixed so as to be embedded in the upper surface of the fixing frame 13, the head of the fixing screw 4 is protected from contact with an external object by the fixing frame 13, and the fixing screw 4 is deformed. And can be prevented from being damaged.

The head of the fixing screw 4 exposed on the upper surface of the fixing frame 13 is covered with the sealing material 3. The sealing material 3 is filled so as to be flush with the upper surface of the fixed frame 13, and a concave portion for storing sand or water is not formed in the upper portion of the sealing material 13. It is possible to prevent wear, damage, etc. from coming into contact with.

  As shown in FIG. 4, when the main body frame 1 and the outer frame 2 are fixed by a fastening member such as a fixing screw 4, the gap between the main body 1 and the outer frame 2 is filled with a sealing material 3, thereby It is possible to prevent sand and water from entering between the outer frames 2, and to prevent the main body 1, the outer frame 2, and the fixing screw 4 from being rusted, deformed or broken. At this time, the sealing material 3 filled in the gap between the main body 1 and the outer frame 2 and the sealing material 3 covering the exposed portion of the fixing screw 4 may be filled separately. Filling in such a manner is preferable because the sealing material 3 is shaped so as to bite into the main body 1 and the outer frame 2 and is less likely to peel off.

Further, as shown in FIG. 6, if a packing 6 formed in a shape that closes the gap is fitted in the gap between the main body 1 and the outer frame 2 instead of the sealing material 3, the main body 1 is removed from the outer frame 2. Since the process of excising the sealing material 3 at the time of removal can be omitted, the workability is improved. However, since the sealing material 3 has better sealing performance on the waterproof surface, it is preferable to select a sealing method in consideration of the installation environment of the self-light-emitting device. If the packing 6 is formed in a shape that closes the upper part of the gap between the main body 1 and the outer frame 2, and the lower part of the gap is filled with the sealing material 3, the packing 6 is fitted to the waterproof surface. In addition to improving the sealing performance, the amount of the sealing material 3 to be excised when removing the main body 1 from the outer frame 2 is reduced, and the workability is improved.

  Further, as shown in FIG. 3 again, the portion of the fixing frame 13 of the insertion hole 19 for passing the fixing screw 4 provided in the fixing frame 13 and the main body frame 11 has a larger diameter than the male screw portion of the fixing screw 4. The female thread is engraved. By providing the insertion hole 19 in which the female screw portion is engraved, when the main body 1 is removed from the outer frame 2, after the fixing screw 4 is removed, a removal jig provided with a male screw portion screwed to the female screw portion is provided. It can be easily removed by screwing into the female thread and pulling it up. The female screw portion is formed as a female screw having a diameter larger than that of the male screw portion of the fixing screw 4 so as to pass through the fixing screw 4 without screwing. The female screw portion engraved in the insertion hole 19 may be provided in the main body frame 11.

  Moreover, when using the cutting bolt 5 for the fastening member that fixes the main body 1 and the outer frame 2, an internal thread portion to be screwed to the cutting bolt 5 is provided at each bolt insertion portion of the fixing frame 13 and the outer frame 2, The cutting bolt 5 is screwed from above the fixed frame 13. At this time, by screwing until the upper end of the cutting bolt 5 is buried in the fixed frame 13 so that it does not protrude from the upper surface of the fixed frame 13, an object comes into contact with the upper part of the cutting bolt 5 from the outside and is deformed or damaged. Can be prevented. Further, by covering the exposed portion of the upper part of the dimensioning bolt 5 with the sealing material 3, it is possible to prevent sand, dirt, water, etc. from contacting the head of the dimensioning bolt 5. Deformation, wear and rusting in the head can be prevented. In addition, since the bolt insertion portion of the main body 1 is provided with a female thread portion that is screwed with the dimensioning bolt 5, when the main body 1 is removed from the outer frame 2, after the dimensioning bolt 5 is removed, The removal jig provided with the male screw portion having the same shape as the male screw portion 5 can be screwed in and pulled up and removed easily.

  Further, when the sealing material 3 is not filled in the gap between the main body 1 and the outer frame 2, water may enter between the main body 1 and the outer frame 2, so that water that has entered the outer frame 2 is drained. Therefore, it is preferable to provide a drain hole 21 at the bottom of the outer frame 2.

  When the outer frame 2 is buried, mortar material, cement, or the like is filled around the outer frame 2, so when the drain hole 21 is provided, the water drained from here is blocked by the mortar material. It is necessary to provide the drainage passage 71 so as not to exist. As a method of providing the drainage passage 71 in the mortar layer 7, when constructing the outer frame 2, a construction member 9 extending from the drainage hole 21 to the water permeable layer 8 is attached and projected from the inside of the outer frame 2, A method of removing the construction member 9 from the inside of the outer frame 2 after the mortar material is filled around the frame 2 and solidified can be used. The construction member 9 may be fixedly inserted into the drain hole 21 using a taper pin, but if the drain hole female thread 22 is formed on the side wall of the drain hole 21, the male thread can be screwed into the threaded hole 21. Can be easily attached to the outer frame 2 as a construction member 9. The material of the construction member 9 is preferably made of resin, so that the length can be easily adjusted by cutting according to the distance between the bottom bottom surface of the outer frame 2 and the water permeable layer 8. A wooden thing etc. may be used.
