Abstract:
PURPOSE: To simplify a light admission device, and also to reduce the weight thereof by providing a plurality of light-screening bodies to the inside of the light admission part that has been provided in a dome-shaped roof, so that the amount of light to be admitted can be regulated by changing the space between light-screening bodies.
CONSTITUTION: A plurality of light-screening bodies 8 are provided to the inside of a light admission part 5 of a circular shape in plan view that has been provided in a fixed dome-shaped roof 1. There are various structures of the light- screening bodies 8; as an example, light-screening membranes are provided at intervals to the frames like umbrella ribs, and when the umbrella is opened, light is entirely intercepted all over the surface, and the amount of light to be admitted is regulated according to the opening of the umbrella. In other words, the light admission amount is regulated by moving a center frame 7 up and down. Thus, the amount of light to be admitted can be regulated by means of a simple and lightweight device.
