園等に設置するものには適用できないのが実情である。However, the above-mentioned steel lighting device has a problem that it is expensive, rusts easily and impairs aesthetic appearance. Further, the conventional wooden lighting device is easily rotten due to containing water such as rainwater and must be replaced frequently, so that maintenance is not only costly but also results in loss of wood resources. It was also considered to apply a preservative to the wooden lighting device, but the preservative is highly toxic, as represented by CCA (chromium / copper / arsenic compound), and may have an adverse effect on the human body. For this reason, it cannot be applied to a device installed in a park or the like that is a place for children to play.
【０００４】本発明は、このような事情に鑑みなされた
もので、安価で外観がよい照明装置の提供を目的とす
る。The present invention has been made in view of such circumstances, and an object of the present invention is to provide a lighting device which is inexpensive and has a good appearance.

常に安価であるうえ、木材資源の保護にも寄与すること
ができる。That is, in the lighting device of the present invention, a notch is formed in a part of a log, and an electric lamp is provided in the notch. For this reason, the grain of the log is decoratively projected on the inner surface of the notch recess, and the portion of the decorative surface is illuminated by the electric lamp, so that the appearance is beautiful and the appearance is extremely excellent. In addition, since the waste material generated in the lumbering process can be used, it is very inexpensive and can contribute to the protection of wood resources.

腐性能を飛躍的に高めることができる。In the lighting device of the present invention, by infiltrating and solidifying the synthetic resin liquid into the surface layer of the log in which the notch recess is formed, it is possible to prevent moisture from entering the inside of the log and to evaporate the water inside the log. If it is reduced, decay fungi and bacteria hardly enter the log. In addition, the interior of the log creates an environment where bacteria and termites are unlikely to inhabit. Then, since the synthetic resin permeates and solidifies in the surface layer portion, the log does not repeatedly dry and wet. As a result, the decay rate of the log can be greatly reduced, and the preservative performance can be dramatically improved.

させることができる。Furthermore, since no toxic preservatives are used unlike the prior art, there is no concern about environmental pollution due to the dissolution of the chemicals into the surrounding environment. Furthermore, since the evaporation of the water inside the log is reduced, the shrinkage deformation of the log can also be reduced. This prevents cracks and the like due to aging, prevents the inside of the log that is not impregnated with resin from being exposed to the surface, and can maintain the antiseptic effect for an extremely long time. In addition, since the synthetic resin liquid permeates and solidifies the log surface layer, the occurrence of mold can be reduced.

優れた耐候性も得ることが出きる。In the lighting device of the present invention, when the synthetic resin liquid is a synthetic rubber or a synthetic resin emulsion, the antiseptic treatment is performed using a synthetic rubber liquid or a synthetic resin emulsion which is easily available and relatively inexpensive. Processing costs can be reduced. In addition, there is almost no problem of environmental pollution such as scattering of solvents, and the safety is extremely high.
Excellent weather resistance can also be obtained.

０．００１μｍ程度である。The emulsion liquid preferably has a particle diameter of dispersed particles of 10 μm or less, more preferably 5 μm or less. If the particle size exceeds 10 μm, the size of the voids in the wood is about 10 μm, and thus the dispersed particles of the synthetic resin do not sufficiently penetrate into the wood, making it difficult to obtain the desired preservative effect. . Further, as the above-mentioned particle diameter, the most preferable is that the size of the voids in the annual ring portion where the density of the wood is high is about 1 μm, so that 1 μm or less where the dispersed particles of the synthetic resin can sufficiently penetrate the annual ring portion. is there. The lower limit of the particle size of the dispersed particles,
It is about 0.001 μm from the characteristics of the emulsion liquid that the colloid is dispersed.
