technical field

The invention belongs to the technical field of building sunshade, in particular to a sunshade whose direction changes with the light.

Background technique

In hot summer areas, shading has a significant effect on reducing building energy consumption and improving indoor living comfort. The types of building shading include window shading, roof shading, wall shading, and greening shading. Among these groups of shading measures, The window is undoubtedly the most important.

Traditional sun visors need to be manually adjusted to change the angle of the sun visor. They do not have the ability to change the angle according to the light. Some areas such as offices or classrooms require a certain brightness and air permeability, and the sun visor needs to be adjusted when strong sunlight is not needed. However, the angle of the sunshade will change as time goes on, requiring the user to manually adjust the sun visor frequently, which is not convenient for the user and cannot satisfy the user's use effect.
