This design focuses on solving the problem of night illumination for African children.As known, there is ample supply of sunshine while the
provided energy for daily use is quite insuffcient. Consequently, a large number of children are not able to study at night because shortage of
light. SUN-TRAY makes light material into a tray which absorbs and stores the solar energy in the daytime, and transforms the energy into
luminous energy at night. So studying at night is possible for African children.
