Abstract
A lighting apparatus includes a solar plate, a battery, a driver module, a light source, a lens tube, a main housing and a plugging bar. The solar plate converts a sunlight to an electricity. The battery stores the electricity. The driver module converts the electricity stored in the battery to a driving current. The solar plate is placed on a top side of the driver module and the light source is placed on a bottom side of the driver module. The lens tube has a top opening and a bottom opening. The top opening has a larger size than the bottom opening. The top opening is closer to the light source than the bottom opening. A light of the light source is emitted via a lateral lens surface of the lens tube between the top opening and the bottom opening.
