US 10,309,600 B2 · Daylight transmission system for building

Abstract

A daylight transmission system that can be used in buildings, the system including: dual-axis implementation device, CPU-controller, light position sensor and optical components that include moving and fixed optical components; with the moving optical components including optical light collector and the fixed optical components including first receiver and consecutive receivers. The invented system transmits sunlight in a form of parallel light after it is concentrated and therefore does not rely on expensive medium such as optic fibers, with the entire process being efficient in light transmission and economically viable. With the help of a tracking device, sunlight of any incident angle will be reflected in a fixed direction and to a fixed point where the light is reflected further on to the desired destination inside of a building. The invented system can be installed directly onto the external wall of any building, and be applied within a wide range of buildings.
