An optical system for a solar lighting device to provide highly concentrated sunlight to interior spaces with minimal disruption of building envelope. The optical system includes an aplanatic optical imaging system mounted on a dual-axis sun tracker, a non-imaging solar concentrator coupled to the aplanatic system, a liquid light pipe to convey the very intense solar flux to the interior of a building, a diffusing light fixture to spread the daylight into the interior space, and a control system to regulate the light output to a constant and desired level.
