A skylight is a window on the roof. Why did it open? What did it open?

Skylights are windows on the roof for lighting and ventilation.

Open a small square hole in the roof and install glass. This is called "skylight". Because the room is dark after the wooden window is closed, the main function of opening the skylight is to illuminate the room and make it scattered and bright. Skylight lighting and ventilation efficiency is high.

Skylights are widely used in modern buildings. According to their structure, location and relationship with the roof, they can be classified into three types: zenith type, convex type and concave type.

Advantages and disadvantages of skylight

Advantages of skylight: after using skylight, it can increase the amount of lighting and make the light evenly distributed. It has the advantages of simple structure, convenient layout, low cost and clear light direction, which is beneficial to the formation of shadows and is suitable for viewing objects with strong three-dimensional sense and outdoor landscapes.

Disadvantages of skylight: the illuminance distribution of skylight is uneven, the illuminance near the window is high, and the horizontal illuminance far away from the window drops rapidly. When the lighting area is equal and the elevation of the window bottom is the same, the square window has the largest lighting quantity, followed by the vertical rectangle and the horizontal rectangle.
