LIGHTING SYSTEM FOR SUNLIGHT, AND TOP LIGHT WITH POWER GENERATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive top light with good construction efficiency that has a tracking mechanism for sunlight and is constituted to have a photovoltaic power generation panel in a camp shape installed at a periphery of a riser base where the tracking mechanism for sunlight is mounted.

SOLUTION: After an opening part edge riser member is provided and fixed on a roof part on four sides of a lighting device body for sunlight, the photovoltaic power generation panel is installed on four sides between a top end of the riser member and a reflecting plate duct frame through a photovoltaic power generation panel frame, and electric power of the photovoltaic power generation panel in the camp shape is accumulated in a storage battery to drive the tracking mechanism for sunlight.
