Achieving efficient solar lighting, spectroscopically with reflectors of various configurations, achieves solar lighting in multiple places, and maintains the overall water tightness so that it can be used in water.

In general, solar energy is heat energy and light energy that radiant energy radiated from the sun penetrates the atmospheric layer and reaches the earth's surface.

Solar energy is not only a clean energy resource that can be obtained indefinitely without energy sources such as fossil fuels being exhausted, but also has the advantage of not causing pollution and environmental pollution. Is being used.

For example, in the case of solar lighting that draws sunlight into an indoor or dark basement for lighting, a condenser that collects sunlight is installed outdoors, and an illuminator is installed in the room, and then The condensed light is transmitted by connecting the condenser and the lighting unit by an optical cable (or an optical fiber) that is a transmission means, so that the indoor or underground are illuminated.

The optical cable is a configuration in which the concentrated solar light is incident to one end of the optical cable within a predetermined angle, the solar light is totally reflected at the core and cladding interface and transmitted to the lighting unit, the concentrated solar light must be incident within a certain angle to one end of the optical cable. Therefore, not only a lens is required for the light collecting portion, but the diameter of the optical cable is mostly about tens of micrometers to about 1mm, which causes a problem in that solar transmission efficiency and lighting efficiency are greatly reduced.

In addition, even if bundles of optical cables are bundled in bundles to increase their diameter, construction may not be possible due to factors such as low bending stress and weight increase due to the characteristics of glass or acrylic materials.
