A solar lighting apparatus (10) includes a transparent dome (16). The transparent dome (16) is provided, at its ceiling center, with a control box (50) accommodating a stepping motor (42), a controller (46) for controlling the motor and a secondary battery (48). The stepping motor (42) has a motor shaft coupled with a rotary shaft (34). On the rotary shaft (34) is coupled a support frame member (20) through a universal joint. The rotary shaft (34) is driven by the motor (42) to turn a reflection mirror (22,24) held on the support frame member (20) over a predetermined angle while tracking the sun. <IMAGE>
