Light collecting device

Abstract

Equipped with a solar power generation device that includes a light collecting member that collects and irradiates sunlight, a drive device that drives the light collecting member, and a control device that controls the drive device, and that has at least one solar cell panel. A light collecting device that irradiates light to a parked vehicle using a light concentrating member, the control device determining the power generation efficiency of solar power generation by the solar power generation device based on the position of the solar cell panel. The drive device is controlled so that the power generation efficiency is equal to or higher than the initial power generation efficiency that is the power generation efficiency at the initial position of the light collecting member.
