Description

The present invention relates to a high-performance solar light collecting system, and more particularly to a high-performance solar light collecting system that can directly collect sunlight and energy and can be used for a system inside a house or office building.

The use of solar energy to develop science is the most environmental protection and does not destroy nature. The sun itself contains abundant light energy and heat energy, and this kind of energy can not only be used directly, but also can be stored or converted into new energy. For this reason, it can be used as an energy tool for horticulture, landscape creation, indoor lighting, power generation (heat), etc. in houses and office buildings. it can.

Many large buildings in places where people are concentrated, such as communities and office buildings, have a courtyard to make life easier. In the courtyard, there are plants and ponds. In order to be as close as possible to nature, a semi-transparent ceiling and glass material are used at the top of the courtyard. However, when the sunlight rays from the outside pass through the translucent plate and reach the courtyard, there is a drawback that the brightness of the illumination is not sufficient, and the courtyard is humid and dark. Also, in order to pursue brightness, lighting fixtures and light bulbs may be attached, which requires power and increases costs. Therefore, if there is a device that can use solar energy, not only can a natural light source be used, but also heat energy can be collected and used for other heating and power generation, with much energy and cost. Can be saved.

Conventional devices for collecting sunlight are disclosed in US Pat. Nos. 6,128,905 and 6,691,701. This device collects a lot of sunlight with a large main reflector and projects it onto a secondary reflector in front, which further reflects the light beam into a hole in the center of the large main reflector. In addition, the light beam is guided to the inside by an adjustable plane reflecting mirror and used. The apparatus described above has the following drawbacks.
1. Reflection and guidance of light are directly projected and transmitted from the reflecting mirror piece, both of which do not converge and conduct efficiently, and are susceptible to the effects of dust and dust from the outside air, so the loss of light is large. The collection efficiency of light energy and heat energy is low. This is a major drawback of the prior art.
2. The opening angle of the sun is approximately positive and negative 0.26 degrees, and adding the accuracy and error of the tracking platform to it, the total error reaches 0.5 degrees positive and negative. That's not true. The most important point of the conventional technique is that a two-dimensional space design that adjusts the elevation angle is adopted for the function of chasing the sun. For this reason, there is a limit to the adjustment that is accurately directed to the sun. In addition, by setting the installation to a three-dimensional adjustment angle design, it can be accurately directed to the moving sun, and high-performance sunlight can be collected efficiently. However, conventional devices do not have this function.
3. All conventional systems consist of a single medium reflector or a plurality of small Fresnel lenses. Therefore, the total light amount of the entire system is limited and cannot be changed. This is also one of the drawbacks of the prior art.

And, since it is transmitted to the application tube member 40 in a sealed state, the light beam is not lost. At the same time, it is one of the advantages of the present invention that necessary energy (UV or IR) can be stored and sunlight can be used efficiently.
3. Since the present invention is equipped with an optical filter (UV or IR) at a special position, it adjusts the room temperature by inducing infrared rays to light or energy that needs to be removed or increased. It is also one of the advantages of the present invention that it can be connected to a solar energy storage board to make the architectural design more human, and realize energy saving and environmental protection.
