The sun is the main source of daylight, so it is necessary to make use of it as much as possible in the interior spaces, mainly in dim spaces to save energy. The problem occurs in houses surrounded by high buildings that block sunlight/ daylight. To overcome this issue the study presents a modern technology that provides the following two methods:
-          The first method is Parans solar panels.
-          The second method is the solar tubes that allow polarizing sunlight.
The research method is a descriptive approach that clarifies the components of modern technological systems and guarantees the role of the interior designer in lighting dim spaces, as well as the importance of daylight in reducing the demand for industrial energy. The first method of modern technology is the Parans plate system, which are lenses that follow the mechanisms of the sun to reflect light in interior dark areas. Those plates are attached and fixed to the ceiling by lens, then directed inside a building using optical fibers; they are also equipped with sensors that allow automatic movement depending on the movement of the sun. This system is installed on surfaces or façades to allow architectural integration. As for the second proposed method, the solar tubes that allow polarization of sunlight by a dome made of polyethylene and aluminum tube coated from the inside with highly reflective materials.
The following results are concluded from the study:

It is easy to link interior spaces to the exterior surrounding environment with the use of modern methods.
Solar tubes and other reflective systems have long allowed daylight to pass to the lower levels of the basement interior.
Solar tubes vary in areas (elastic - solid), all of which are subject to the idea of introducing natural lighting, and the longer the length of the solar tubes, the lesser the reflections.

Therefore, the author recommends introducing natural lighting into dark interior spaces by developing production of other new systems in addition to the herewith studied Parans panels and solar tubes.
