Window structure with sunshade daylighting panel

Technical Field

The utility model belongs to the technical field of the building sunshade. In particular to a novel external window structure which can adjust the effects of shading and lighting of a room by changing the light path direction of natural light, comprising a shading and lighting board and skylight glass.

Background

For buildings, natural light comprises the characteristics of radiometry and photometry, wherein the radiometry characteristic is embodied in heat brought by radiation and determines the cold and hot loads in the building; the photometric characteristics are reflected in that the radiation intensity determines the illumination and uniformity of indoor lighting. In a building, light rays near a window are strong, and received radiation heat is also large; the light far away from the window is weaker, and the lighting uniformity of the room with larger depth is worse. The window is used as an important component of an enclosure structure for receiving solar radiation, is an important factor influencing indoor thermal environment, and is a determining factor influencing indoor luminous environment. Therefore, the window structure with the sun-shading and lighting effects is worthy of research, development and application.

The common window structure is divided into an upper window and a lower window or a left window and a right window according to the opening function except for a frame, and does not have any sun-shading and lighting facility. For the personnel that the room used like this, there is the photo-thermal environment even different, the comfortable and the comfortable relatively poor condition of experiencing of heat of vision. In recent years, designs of sunshade facilities for buildings have gradually appeared, and some students have started to use sunshade, etc. facilities to efficiently utilize sunlight to improve indoor light environment while reducing consumption of non-renewable energy for artificial lighting. However, in different areas, different seasons and different times, people have different requirements for indoor light and heat environments, and the current sun-shading facilities do not fully consider the use requirement. Therefore, it is important to dynamically improve the indoor light environment.
