Compared with the prior art, the utility model has the beneficial effects that:

1. the sunlight of high incident angle is sheltered from in summer to through photovoltaic board reutilization, for the motor power supply, compare with prior art and save energy more, accord with green building theory.

2. Direct light is the diffuse light entering indoor for indoor light environment and space atmosphere are more comfortable, and shading performance obtains improving.

3. The light with low incident angle in winter is projected to the room again through the curved surface with high reflectivity, and the lighting efficiency is improved.

4. The light-shading angle is dynamically adjusted by the light-tracking system, so that the system is suitable for all-weather modification of comprehensive light shading in all dimensions and all seasons.

In conclusion, the utility model overcomes the problems that the existing shutter can not accurately adjust the shading angle according to the incident angle of sunlight and the existing shutter skylight can not convert direct light into diffused light (an intermediate state of direct light and no light), can build a comfortable light environment indoors and also improves the energy-saving and environment-friendly effects of buildings.
