This paper presents a novel design for the controller of the solar-luminaire daylighting system which is fully utilized as
the indoor illuminance source with no other power assisted. The controller could precisely trace the sun azimuth to drive
reflectors which insure the system collecting the sun light in the most extend, and it is usually worked in the mode of
ultra low power consumption via the solar panel, because the low-power consumption method is specially adopted,
which realizes green lighting.
