Problems solved by technology

However, the conventional shading device is operated manually rather than automatically, so it cannot quickly adjust the light transmittance as the sunlight intensity changes
Also, the blackout function will not work when no one is in the building

Abstract

An auto light-shading system is disclosed, which includes a photovoltaic module for providing an electric power, a liquid crystal panel connected to and driven by the photovoltaic module, and a UV filter applied on the liquid crystal panel. A light transmittance of the light-shading device is determined by an output power of the electric power of the photovoltaic module.

Description

technical field [0001] The invention relates to a shading device. More particularly, the present invention relates to an automatic shading system. Background technique [0002] The conventional shading device may be blinds or curtains. Shading devices can be placed on the windows to prevent excess sunlight from passing through the windows directly into the building. However, the conventional shading device is operated manually rather than automatically, and thus cannot quickly adjust the light transmittance as the intensity of sunlight changes. Also, the blackout function will not work when no one is in the building. [0003] Therefore, there is a need to provide an automatic shading system. Contents of the invention [0004] A technical problem to be solved by the present invention is to provide an automatic shading system. [0005] An embodiment of the present invention provides an automatic shading system, which includes a photovoltaic module for providing electric...
