## Abstract

An energy-saving lighting masonry module is disclosed. The module is mainly composed of a structural part, a thermal insulation part and a light transmitting part. A lens on an inlet end of a refraction region of the light transmitting part changes an optical path so that the light enters a total reflection light channel, and a lens on an outlet end restores the optical path to provide indoor illumination. The present invention uses the lenses and light guide to change the optical path to compress the light channel. The insulation material and optical devices in the energy-saving lighting masonry module are combined to form a block to achieve the combination mode of dual purposes of lighting and energy saving.
