It relates to a visual display device using water sunlight.

Recently, various natural light lighting devices for illuminating a room using natural light have been developed.

As an example, a solar lighting system has been proposed. The solar lighting system collects sunlight through a mining device, and then transmits the collected sunlight to a desired place using an optical transmission means, for example, an optical fiber, a reflector, a light duct, and illuminates the transmitted sunlight. It is configured to illuminate the desired place through the device.

On the other hand, in such a natural light lighting system, it is an important task to efficiently collect sunlight, which is a light source, and transmit more sunlight into the room.

In accordance with this request, utility model registration application No. 20-2001-0023013 (lighting device using sunlight) dated July 26, 2001 was proposed,

This is a device for providing lighting in a room using sunlight, the device comprising: a light collecting unit for collecting light emitted from the sun; and a light collecting unit for dispersing the light incident from the light collecting unit; A light transmission unit for transmitting the light split by the spectrometer and an illumination unit for illuminating the light using the light transmitted from the light transmission unit are generally used.

On the other hand, in the past, it has been mainly used for buildings with a sacred religious atmosphere, such as cathedrals and churches, and in recent years, it can be seen that it is used a lot in domestic hotels, high-class restaurants, and popular cultural spaces such as department stores and subway premises. The stained glass in the room is made by matching the glass with various colors to the picture designed in advance to suit the atmosphere of the indoor space.

In addition, since the transparent characteristic of glass that allows light to pass through such stained glass and the ability to mosaic by combining glass of various colors can be used, it is possible to create a beautiful interior space in which colors are harmonized.

In addition, since the transparent characteristic of glass that allows light to pass through such stained glass and the ability to mosaic by combining glass of various colors can be used, it is possible to create a beautiful interior space in which colors are harmonized.

However, using the fact that the transparent property of the glass that allows light to pass through is one of the characteristics of the glass for manufacturing stained glass, it is currently in the spotlight as one of the lighting means.

However, since lighting devices using such stained glass are often used in buildings or basements, the time cannot be checked in many cases.
